The Conceptual Design of LG Folding Screen and Rolling Screen Intelligent Machine Is Exposed Or Perf
The Conceptual Design of LG Folding Screen and Rolling Screen Intelligent Machine Is Exposed Or Perf
As early as last November, the conceptual design of LG's folding screen and rolling screen intelligent machine has been exposed on the network. During the online activity of LG wing rotary screen smartphone in September, the company also revealed more possibilities of the "Explorer project". Recently, letsgodigital, a Dutch technology blog, also found a design patent application for "scroll screen mobile device terminal" submitted by LG Electronics to the U.S. patent and Trademark Office (USPTO) in August 2019.(from: letsgodigital)On September 24, 2020, this document was finally released to the outside world and included in the database of the World Intellectual Property Organization (WIPO). It can be seen that a device with a flexible screen is depicted, and it can be partially rolled up for compact storage.(Figure via letsgodigital)Without stretching out, this concept device is about the size of an ordinary smart machine. However, if you stretch left or right, the border can also move synchronously. In addition to providing protection for the equipment, the rubber edge also has a fairly good hand feel.(Figure via letsgodigital)If you want to actually build such a device, LG will obviously adopt the design scheme of flexible OLED screen metal shell. In order to fill the gap of the metal frame, the flexible sub frame can also provide corresponding protection and support for the screen edges at the top and bottom.(Figure via letsgodigital)Since the screen extends from both sides, the occupation of fuselage space is relatively small, so that the equipment can accommodate all necessary related components. Compared with a patent obtained by LG last year, the design without stretching from the middle of the screen is obviously easier to achieve.(Figure via letsgodigital)As for the mechanical structure of the rolling screen, LG envisages the scheme of using gear elastic elements and preventing the screen from sliding out or retracting accidentally through a "chute" or locking mechanism. If the flexible screen is stretched or rolled up too quickly, it is likely to make the crease more obvious.(Figure via letsgodigital)However, compared with the current commercially available folding screen models, LG is expected to make the retractable screen more durable. LG may allow users to bend the device to a specific position to avoid the greatest risk of damage to the screen on the broken line.(Figure via letsgodigital)In terms of function, the extended screen can not only be used for parallel multitasking, but also for virtual keyboard, or simply provide the maximum viewing experience.(Figure via letsgodigital)In terms of photography, this concept device may adopt the combination of infinity-o perforated screen front photography rear three photography. In addition, the power / volume adjustment buttons are located on both sides of the device, and the bottom is a microphone / dual speaker / usb-c port.Finally, according to Neowin's report last weekend, LG is developing a rolling screen intelligent machine code named "B project". If all goes well, we may officially welcome it in March 2021.Original title: LG roll screen intelligent machine new design patent exposure or release in March 2021The source of the article: WeChat official account: Fuling Huaqiang electronic world] welcome to add attention!

Can the Laptop Power Adapter Be Universal
Can the Laptop Power Adapter Be Universal
We have all used the power adapter. The common one is to use the charging power of the laptop. At this time, we have a question: are notebook power adapters of different brands and manufacturers mixed? That is to ask whether the power adapter can be universal. Here is an analysis of this problem.Whether the power adapter can be universal depends on two factors: the first is the interface. First, the interface must be the same, otherwise it cannot be used. Second, the output current must be strictly consistent, otherwise it will be very dangerous. The laptop is very vulnerable to current overload. Finally, I personally think the output voltage can have a difference of 5V. Because of the voltage requirements of the battery, there can be 5V floating up and down.The main reasons why laptop power adapters of different brands cannot be used in common are as follows:1. Different interfaces, different interfaces. The interfaces between most laptop power adapter brands are different, which means that the power adapter of other brands can not be plugged into your laptop for power supply at all. Different interfaces are relatively safe, because at least you will not plug in a power adapter with inconsistent current or voltage to power the laptop, resulting in damage to the computer hardware.2. The voltages of notebook computer power adapters of different brands are different. For example, generally, IBM is 16V, Dell is 20V, HP is 18.5v, Sony is 19.5V, etc. It can be seen that even if the power adapter interfaces are the same, different brands of laptop power adapters cannot be used for power supply.3. The current of laptop power adapters of different brands varies with the current. For example, generally, IBM is 4.5a, Dell is 3.34a, HP is 2.7A, Sony is 4.1a, etc.Strictly speaking, the power adapters of notebook computers of different brands cannot be universal. Even if the voltage and current provided on the logo are the same, they should not be mixed, which will cause power interface or motherboard failure or even damage. Notebook power supplies of different models of the same brand can be used temporarily, but should not be used for too long. It's best not to buy and use the fake power adapter. There are too many hidden dangers, including spontaneous combustion and explosion. Try to use the original power adapter.

What Is a Compensating Cable_ How to Identify the Compensation Cable
The compensation cable can be used to transmit electric energy on submersible motors with AC voltage of 500V and below. It has good electrical insulation performance under long-term immersion and large water pressure. Waterproof rubber sheathed cable has good bending performance and can withstand frequent movement.The function of the compensation cable is to extend the cold end of the multi-point thermal electrode and mobile thermocouple, and connect with the display instrument to form a multi-point temperature measurement system. The insulating layer and protective layer of the compensation cable are imported high-quality fluoroplastics, and the new overall continuous extrusion process is adopted, so that the product has excellent acid resistance, alkali resistance, wear resistance and non burning performance, and can be immersed in oil and water for long-term use. The service temperature of compensation cable is - 60-260 , which belongs to the contemporary international advanced level. Thermocouple compensation cable is suitable for multi-point connection of automatic temperature measuring instruments in electric power, metallurgy, petroleum, chemical industry, light textile and other industries, as well as national defense, scientific research and other departments.Compensation cable: not less than 12 times the outer diameter of the cable with armor and not less than 6 times the outer diameter of the cable without armor;Insulation resistance (20 ): PVC insulation shall not be less than 25m · km; FEP or pea insulation shall not be less than 100m · km;Flame retardant characteristics: Class A (tested according to gb12666.5-90)Executive standardExecutive Standards for production of compensation cables and wires: GB / t4989-94 and JB / t7495-94Service conditions1. Operating temperature:Heat resistant: up to 200 and 260 .General use: up to 70 and 105 .2. Minimum ambient temperature:Fluoroplastic insulated and sheathed cables: fixed laying - 60 , non fixed laying - 20 .PVC insulated and sheathed cables: fixed laying - 40 , non fixed laying - 15 .3. Allowable bending radius:a) The compensation cable with copper tape shielding shall not be less than 16 times of the outer diameter of the cable;b) The compensation cable of other structures shall not be less than 10 times of the outer diameter of the cable.Model of compensation cableCode name and meaningCompensation cableIntrinsically safe compensation cableHow to identify the compensation cable_ Difference between compensation cable and ordinary cableThe conductors of compensation cables are alloy materials with thermoelectric EMF transmission. Generally, compensation cables are connected with thermocouples.Ordinary cables are electrical products used to transmit electric energy and power supply, so cable conductors are mostly electrolytic copper or electrolytic aluminum with excellent conductivity.This is the most fundamental difference between the two.

Manufacture of Toxic Gas Monitor Based on Internet of Things
Manufacture of Toxic Gas Monitor Based on Internet of Things
Step 1: implement with hardwarePart of the project is mainly handled by the MediaTek linkit one committee.The MediaTek linkit one board is connected with gas sensors, namely grove LPG sensor and grove air quality sensor. The sensor readings will be sent to the ubidots server.In the picture, you can see more gas sensors, such as mq-7, mq-135 and mq-138.However, the linkit one board has only three analog pins. A0, A1 and A2, so up to 3 sensors can be connected.Because the output of the gas sensor is analog voltage, and our board is a digital system (microcontroller).We need to convert analog voltage to digital value. This can be done by using an on-board 10 bit ADC.More information about ADC and gas sensor will be described later.Step 2: ADC analog to digital conversionADC represents analog-to-digital conversion, and the equipment performing the conversion is called analog-to-digital converter.The most widely used ADC chips are ADC0804 and ADC0808 of Texas Instruments (TI).Why do we need ADC?The world we live in is simulated, that is, everything is continuous in time. In order to make these analog signals compatible with digital devices such as microcontrollers, these controllers can only understand digital signals, such as' 0's and '1's.Therefore, in order to convert analog signals to digital form, we need to use ADC.How to perform a / D conversion?Converting an analog signal to digital form involves two steps-1) SamplingSampling means dividing the signal into smaller time slots. For example, if we have a sine wave with a continuous frequency in the time domain, we will sample it, that is, we will obtain the amplitude value of the sine wave at a certain equal time interval, so it looks a bit like the picture2) QuantificationThe second step is to quantify the obtained amplitude value. As with sampling, the amplitude obtained can be any irrational value, such as pi (22 / 7) or 1.33333 or sq.root (2), etc/ p》These values will never terminate, so if you want to store them, they will require an unlimited amount of memorySo we need to round the number to the nearest position.This completes the A / D conversion section.But is this just theory?How to actually execute ADC?The answer is by using an IC such as ADC0804 or ADC0808.The latest microcontroller series such as Arduino and AVR, linkit one, has an on-board ADC, which we will use in our project.Step 3: use linkit one onboard ADCA linkit board has three analog input pins, which means that up to three analog devices can be connected to the board.The word ADC resolution is also important.The onboard ADC has a 10 bit resolution, which means that the input analog voltage will be represented by values in the range of 0-1023, i.e. a total of 1024 valuesHow do I get it?It's simple. A 10 bit ADC means that we will get a 10 bit digital value. That is, 2 ^ 10 = 1024 values.In the decimal range, it will be 0 to 1023.How does it assign numeric values?For an analog input voltage of 0V, we will obtain the corresponding digital value of 0. Analog input voltage, i.e. 5V, we will get the maximum digital value, i.e. 1023.Any analog input voltage between 0v-5v will have a digital value between 0 and 1023.This is the formulaADC reading = (1024 * analog input voltage) / 5So, as you can see, for 0V, you'll get 1024 when the ADC reads 5V (actually 1023, because you start counting from 0 here.)Step 4: gas sensors: how do they work?There are many types of gas sensors. They are classified according to the way gases are detected in the atmosphere.1) Electrochemical typeThe MQ sensor family falls into the following categories: gas sensors. These gas sensors have sensing elements usually made of SnO2 or tin oxide (IV), which is the correct IUPAC name (International Federation of pure and Applied Chemistry) or commonly referred to as tin oxide (not Satan IC).SnO2 layer isIn this case, this phenomenon is called adsorption, which is very different from. This ceramic matrix is usually made of alumina (Al2O3). Absorption.Absorption is a surface phenomenon, which means that gas molecules only accumulate on the surface of SnO2 layer.To increase the adsorption rate, we need heating elements. This is done through the heating coil (wire mesh) on the MQ gas sensor.Heating can increase the adsorption rate. There is a specific pre heating time for each sensor before use.As the gas molecules begin to gather on the surface, we get a voltage proportional to the concentration as the outputThis is the voltage we will measure to detect the gas.Now, due to adsorption, that is, molecules accumulate on the sensing elements of the sensors, these sensors become useless after a few months and need to be replaced with new sensors. You cannot clean the sensor because everything happens at the molecular level.These are the most widely used and available sensors for electronics enthusiasts.In addition to these sensors, we have four other types2) Infrared3) Infrared imaging4) Semiconductor and5) HolographyNow, if you see any MQ gas sensor, it will have 6 pins, 4 for heating purposes and 2 for output voltage and ground.In the picture, you can see the 6 pins of mq-8 gas sensor.The second picture shows the mq-8 gas sensor which is highly sensitive to H2. It can also be used for the detection of liquefied petroleum gas.For reference, I attach this data sheet. It is clear from the data sheet that multiple types of gases can be detected using a single mq-8 sensor.Before continuing, I suggest you read how the gas sensors of the engineer's garage and seeed studio work and how to select gas sensors.Step 5: hardware requirementsTransmitter sideMediaTek linkit one boardGrove air quality sensorGrove LPG sensor ClickSoftware / servicesUbidotsStep 6: register on ubidotsThe first step is to create a free ubidots account!!Ubidots is the cloud service provider we will use.You are free to use any other service.If you re-use other services.Please go to http://www.ubidots.comRegister on the website.Then follow the instructions in the picture.Or follow the instructions below-1) Register on ubidots2) Click the symbol in the upper right corner to add a new source.3) Name your source, such as Intel Edison, Arduino, etc.4) Click source to add a new variable5) Select the type of variable as the meter and set the minimum and maximum limits6) Note the variable ID of each variable you create.7) Now go to your profile and write down the token ID in the API key.Please note that the pictures are from my other projects. Everything remains the same, except that you need to specify a different name and select the display type accordingly.Note the variable ID and auth. Token number. You must enter them in the program.Everyone's numbers are different. Do not copy the image.Step 7: transmitterGrove LPG sensor is connected to A0 pin and grove air quality sensor is connected to A1 pin of mediak linkit one board.The analysisread() function performs the necessary analog-to-digital conversion.The digital value obtained is between 0-1023 (1024 in total) because the resolution of the ADC is 10 bits.Use formulaReading% = (ADC reading / 1024) * 100The program for the transmitter is written in Arduino ide with. Ino files attached.Remember to make the following changes in your code.1) WiFi AP name2) WiFi password4) Token ID, and then upload the code to your development board.Step 8: TestThis is a short video of my general screen, showing you how the meter reading changes when any sensor value changes.For demonstration purposes, I connect A0 and A1 pins directly to the 3.3V and 5V pins on the board.Note: you can also see these values on the Arduino serial monitor as long as the development board is connected to the computer via USB. After removing the USB and using battery power, it will not print values in the serial monitor.

What If the Laptop Keyboard Fails
What If the Laptop Keyboard Fails
Computer keyboard is one of the most commonly used computer input devices, and it is also the most frequently used device. Due to the high frequency of use of computer keyboard, the failure of computer keyboard often occurs in the process of use. Today, I'll share with you the solutions after the computer keyboard fails.There are generally two cases of laptop keyboard failure:One is to press the letter key to turn it into a number. Many friends who know about notebook computers will know that the number keys and letter keys of notebook keypad are integrated. Generally, pressing fnnumlk key can intelligently switch to the number keypad. Some notebook brands may be different. You can refer to your own notebook operation manual.In another case, there is no response to pressing, or the key is not displayed regularly. Most of these are keyboard problems. You can try to clean the notebook keyboard and check each key to see if some keys don't pop up when pressed, resulting in the useless pressing of other keys. In addition, if the notebook keyboard is damaged, you can replace it (but the cost is very expensive), or it's good to buy an external interface keyboard, It's cheap.If none of the above methods can solve your problem, try the following solutions:1. Modify the driver of notebook keyboard.Open the system properties through "my computer", select the hardware tab, and open the device manager. We found that under the Chinese Windows XP operating system, the default keyboard driver is "standard 101 / 102 key or Microsoft natural PS / 2 keyboard". Right click to select update driver, and the hardware update wizard will appear: select "install from list or specified location (Advanced)", click "next", and select "do not search. I want to select the driver to install myself." click "next" to enter the "select device driver to install for this hardware" page, and remove the check box "display compatible hardware" Small hook in front of the. Select "Japanese PS / 2keyboard (106 / 109key)" in the "standard keyboard model" column, click "next", the "update driver warning" pops up, and click "yes". Click Yes in the confirm device installation window. Complete the hardware update wizard and restart your computer.2. Modify the registry.Click "start" menu, click "run", enter "regedit", open the registry and enter "hkey_local_machinesystemcontrolset001controlkeyboardlayouts", which has many subitems. Through observation, I found that the input methods ending with "0804" are simplified Chinese input methods. Open "e00e0804" and you can see that there is a sub item "layoutfile" in the sub item on the right. Double click to open the item, change "kbdus. DLL" in "numerical data" to "kbdjpn. DLL" and click OK. By analogy, you can change "layoutfile" in all sub items ending in "0804" to "kbdjpn. DLL", which is selected according to your common input method. Then restart the computer!There are many reasons for laptop keyboard failure. The more common ones are the two introduced to you at the beginning. In addition, some computer viruses will also destroy the computer keys. It is recommended that you first kill the computer when the laptop keyboard keys fail, and then use the above methods to solve it.Setting method and unlocking steps of laptop keyboard lockLaptop keyboard lock is a tool we often use in our daily life. It makes our work and study more efficient, so it can be widely praised by everyone. However, once we encounter the scene of forgetting the keyboard lock, it will inevitably bring many inconveniences to our life. Therefore, it is very necessary to master some relevant knowledge. Then you might as well learn a few words and pictures about the setting method of laptop keyboard lock and unlocking method with Xiaobian.1 How to unlock the laptop keyboard lockMethod for unlocking keyboard lock of notebook computerWhen starting up, you can directly press F10, and then enter a BIOS page, where you can set the password for the keyboard. Of course, you can set the password and unlock the password. However, it should be noted that different models of laptops have different ways to enter BIOS mode, some with F8 key and some with del key. In this way, you can observe whether the NumLock key of building materials is on. If it is not on, you can turn it on. You can also select the run button in the start menu to enter the run dialog box, enter the regdit command to enter the registry, and then press the following value to change it Defaultcontrolpanelkeyboard] "initialkeyboardindicators" = "2" enter it.Unlocking method 2 of laptop keyboard lockAfter restarting the laptop, observe whether the three LED lights on the keyboard are on. If not, you can try the "windons key" R key to call up the operation window, then enter "OSK" in the dialog box to call up the keyboard on the screen, select "open numeric keypad" in the options, and then click the OK button. Then check whether it is on through NumLock key, and the phenomenon is consistent with the appeal.Unlocking method 3 of laptop keyboard lockAnother simple inspection method is that sometimes it may be because your keyboard (external keyboard) is in poor contact. At this time, all you can do is turn on and off the laptop five times, so that you can release all the static electricity in the computer, then connect it to the keyboard and turn it on again. If it's really just a keyboard problem, then this problem can be eliminated. If the model is relatively new, many computers will have a FN key. If this key is combined with NumLock, it can also eliminate many computer keyboard lock errors.2 How to set the keyboard lock of notebook computer1. Restart the computer. During computer startup, press F2 to check whether BIOS settings can be entered.If the BIOS setting cannot be entered normally, it can be basically judged that the keyboard data connection is loose, and it needs to be sent to the local service network for inspection and maintenance.If you can enter the BIOS normally, it shows that it has little to do with the hardware. It is recommended to observe under what circumstances the keyboard will fail after entering the system.2. Press FN numlk in blue for notebook. Is either FN or shift or Ctrl numlk. The function key FN ESC of the notebook keyboard switches the volume.
Introduction to ADC Configuration by FPGA Through SPI - What Is SPI?
Introduction to ADC Configuration by FPGA Through SPI - What Is SPI?
SPI (serial peripheral interface), that is, serial peripheral interface. It is a high-speed, full duplex data communication bus, and the pins of the chip only account for 4 wires, which greatly facilitates the layout of PCB while saving chip pins. Because of this simple and easy-to-use feature, more and more chips integrate the communication protocol, such as ADC chips we often use.At present, most ADC chips on the market are embedded with special SPI configuration interface. By configuring its SPI interface, you can read and write the internal control register of ADC, so as to flexibly use various functions of ADC chip. Even for some ADCs, if they are not correctly and effectively configured in advance, the ADC cannot work normally.SPI interfaces for ADC configuration are divided into 4-wire mode (such as ad9639 of analog device) and 3-wire mode (ad9249 of analog device). For 4-wire mode, it has 4 signal lines, which are:The difference between 3-wire mode and 4-wire mode is that SDI and SDO signals are combined, which is called SDIO. In addition, the three wire mode of some ADCs is relatively simple. SDIO is only used as the input port SDI (such as ads5281 chip of Texas Instruments). It has no SDO function and is relatively simple to implement.4-wire mode:SDI - serial data is output from FPGA and enters ADC;SDO - serial data is output from ADC and enters FPGA;SCLK - clock signal is output from FPGA and enters ADC;CS - ADC enable signal is output from FPGA and enters ADC;3-wire mode:SDIO - when reading, SDIO is used as the output port SDO, and the serial data is output from ADC and enters FPGA; When writing, SDIO is used as the input port SDI, and the serial data is output from FPGA and enters ADC;SCLK - clock signal is output from FPGA and enters ADC;CS - ADC enable signal is output from FPGA and enters ADC;Compared with the 4-wire mode, the 3-wire mode superficially lacks only one signal line. In fact, the read-write operation involves the three-state conversion control of the SDIO interface between ADC and FPGA, which requires special attention.
