Anonymous users2024-02-05Huawei Glory3cThe distance sensing is an intelligent sensing device,The capacitive screen of the mobile phone is designed to make the mobile phone screen misoperate when the face is next to the screen when playing **,And the distance sensing is designed。 When the user's face is close to the screen, the screen light will go out, and the screen will be automatically locked, which can prevent the user's face from misoperation, when the user's face leaves, the screen light will be automatically turned on, and automatically unlocked.
Distance sensor principle:
This is a machine that detects the physical change of the object using various components and converts the change into a distance to measure the distance displacement from the sensor to the object. According to the different components used, it is divided into optical displacement sensors, linear proximity sensors, ultrasonic displacement sensors, etc. The distance sensor used in mobile phones is a sensor that uses time measurement to measure distance.
Infrared pulse sensors calculate the distance to an object by emitting a particularly short pulse of light and measuring the time it takes from the time this light pulse is emitted to the time it is reflected back by the object.

Anonymous users2024-02-03The capacitive screen of the mobile phone in order to hit the screen will not make the screen jump when the face is on the screen, and the design of the distance sensing, when the mobile phone is very close to the human body or objects when the screen light is turned off, this is the effect of the distance sensor.

Anonymous users2024-02-02Mobile phone sensors are divided into: light sensors, distance sensors, and gravity sensors.
Gravity sensing is now widely used in smartphones, such as Apple's iPhone 4, Samsung i9100 and other mobile phones have this function. What exactly is gravity sensing? For example, when a mobile phone is horizontally positioned, the screen also jumps to a horizontal display, and when playing racing games, you only need to swing left and right to control the direction, both of which are caused by the gravity sensor, which is more convenient for people to use in their daily lives.
What are light sensors and proximity sensors? As the name suggests, the light sensor is a component that is more sensitive to light, generally located at the top of the screen, it will adjust the screen brightness according to the intensity of the external light, so as to achieve the best vision and the dual effect of power saving, the automatic adjustment in the brightness adjustment option of the mobile phone is the use of this function.
In addition, the proximity sensor is mainly used in calls, when the mobile phone is close to the head, it will detect the distance between the mobile phone and the head, and after it is close to a certain extent, the screen light will go out, which is convenient for users to use and also saves power.
The settings of these mobile phone sensors are designed for the user to be more comfortable, I have to say that its existence is greatly convenient, mobile phone users use it daily, and the operation is also very convenient, basically no user to adjust, of course, you can also choose to turn off some of the sensor functions, such as automatic rotation of the screen.
Hello! Hopefully, the following will be helpful to you.

Losing is not normal, I have been playing Chenghai for a few months, playing on Haofang all day, I can win once or twice a day and be happy for 1 night, either a master, or Laipi, either run without principle, or run without principle, or run without a good run, the people on Haofang can be said to play the style that can't hide to the extreme, I personally think that losing is not afraid, that is, afraid of playing to affect the mood, playing too much on Haofang can make a patriot doubt the quality of the Chinese.
I haven't used the key elf.,But the words of the rebuild are all the same.,The reason why I want to rebuild,It's because the default control key in the inventory in Chenghai is the 784512 of the keypad.,The right hand controls the mouse.,The keypad is difficult to press.,If you use the mouse point alone,,The speed is very slow.,So use the remodeling tool to change the keypad 784512 to the left hand can be pressed to the key that doesn't conflict with the skill keys in Chenghai.,For example,I'm used to putting silence and teleportation at the top of the inventory.,The corresponding keypad is 7 and 8., I used the remodeling to change the 7 key, change the 8 to the space bar, so that it is very convenient to press, if with hurricane and purification, you can also change the keypad 4 or 5 to the q key, the specific modification should be the same: open the remodel, click on the default key, and then enter the key you want to change. And run the game after the change, don't forget to turn on the reconstruction, otherwise it's useless.
