Abstract:
A battery protection system applicable to an electronic device includes a battery, a control module, a message generating module and an input interface. The control module is electrically connected to the battery for detecting if the battery is in an abnormal state. The message generating module is electrically connected to the control module for generating a battery-error warning message when the control module detects that the battery is in the abnormal state. The input interface is electrically connected to the control module for transmitting a user command to the control module after the battery-error warning message is generated, thereby enabling the control module to release the abnormal state of the battery according to the user command. A battery protection method is also provided.
Abstract:
An optical touch module is disposed on a display. The display has two edges opposite to each other and a plurality of corners. The optical touch module includes two frames, a plurality of light-emitting units, a plurality of sensors, and two retro-reflectors. The frames are respectively disposed on the opposite edges. The light-emitting units are respectively disposed on the frames and correspond to different corners. The sensors are respectively disposed adjacent to the light-emitting units. The retro-reflectors are respectively disposed on the frames and reflect light emitted by the light-emitting units, such that after the light is reflected, the light travels in the reversed original direction and is captured by the corresponding sensors.
Abstract:
A tray assembly configured for carrying a storage device is provided. The tray assembly includes a carrier, a base frame, a handle and a connecting rod. The carrier carries the storage device. The base frame slidably connects with the carrier, allowing the carrier to slide between a first position and a second position relative to the base frame. The base frame includes a locking part and the handle pivots to the base frame. Two ends of the connecting rod respectively pivot to the carrier and the handle. When the handle rotates relative to the base frame and drives the carrier to slide to the first position, the carrier is carried on the base frame and the handle locks up with the locking part. When the handle rotates relative to the base frame and drives the carrier to slide to the second position, the carrier tilts relative to the base frame.

The controller sub-system performs a security information exchange procedure with a Wi-Fi AP radio access interface. The controller sub-system establishes a data transmission channel with the UE according to the security parameters.
Abstract:
A virtual control device is provided for an electronic device. The virtual control device includes a first lens, a second lens, a first photosensitive unit, a second photosensitive unit and a processor unit. The first photosensitive unit is arranged behind the first lens by a focal length, and obtains a first image via the first lens. The second photosensitive unit is arranged behind the second lens by the focal length, and obtains a second image via the second lens. The processor unit determines the object-position coordinates of a virtual control plane according to a first position of the projection of the object on the first photosensitive unit and a second position of the projection of the object on the second photosensitive unit, and the processor unit provides the object-position coordinates to the electronic device.
Abstract:
A capacitive touch panel provides a partially high-resolution by mixing multiple resolutions. The capacitive touch panel includes a first electrode layer, a second electrode layer, an insulating layer, and a single one integrated circuit chip. The first electrode layer and the second electrode layer respectively include multiple sensor electrodes disposed with uneven density, so that a part of the touch panel has higher resolution, and other part of the touch panel has lower resolution. The capacitive touch panel provides partially higher resolution by adjusting the distribution of the electrodes without increasing the number of pins of the integrated circuit chip.
Abstract:
A head mounted display and a control method thereof are disclosed. The control method comprises following steps. An application processor controls a pico projector unit to project a virtual image having a virtual object located on a virtual image coordinate in a virtual image coordinate system. An eye image sensing unit captures an eye image data. A sensing apparatus senses a touch object to output a sensing data. An ASIC obtains a real image coordinate of the touch object in a real image coordinate system according to the sensing data. The ASIC obtains a pupil position according to the eye image data, and controls the adjustment unit to adjust an imaging position of the virtual image according to the pupil position. The ASIC determines whether the touch object touched the virtual object according to the pupil position, the real coordinate and the virtual coordinate.
