Systems and methods for managing display power consumption are disclosed. In some embodiments first information is displayed in an available display area including a first portion of a display screen in a configuration having a set of portions. The set of portions includes the first portion of the display screen, which is configured in a powered-on state to perform display functions and receive user input, and a second portion of the display screen, which is configured in a powered-off state. Responsive to a user indication in the in the first portion, the second portion is added to the available display area by transitioning the second portion to the powered-on state to perform display functions and receive user input. Second information is displayed in the second portion.

A power-saving sensing module includes a light source, a first and a second sensor, a first and a second detection unit, and a controller. The first sensor detects a first image corresponding to a working plane in response to at least a part of the light ray from the light source to generate a first sensing signal. The first detection unit generates a displacement signal in response to the first sensing signal. The second sensor detects a second image corresponding to an object in response to at least a part of light ray to generate a second sensing signal. The second detection unit generates a touch signal corresponding to the object in response to the second sensing signal. The controller outputs a control signal in response to the touch signal. The first detection unit operates at a dormant state or a sensing state in response to the control signal.

There is provided a displacement detection device including an image sensor, a light source, a light control unit and a processing unit. The image sensor captures image frames at a sampling frequency. The light source provides, in a speed mode, light for the image sensor in capturing the image frames. The light control unit controls the light source with the speed mode to turn on at a lighting frequency or to turn off serially. The processing unit calculates a displacement according to the image frames captured when the light source turns on to be served as an estimated displacement for an interval during which the light source turns off. There is further provided an operating method of a displacement detection device.

A power-saving computer mouse having installed therein a switching transistor and a proximity sensor switch formed of a capacitive proximity sensor and a charge induction plate for controlling said switching transistor to switch on the power supply circuit when the user holds the computer mouse with a hand, or to switch off the power supply circuit when the user moves the hand away from the computer mouse.
摘要:
An electrical hand-held device is provided with improved proximity detection, which can be placed on a surface and has at least one transmission electrode, at least one reception electrode and at least one compensation electrode arranged between transmission electrode and reception electrode. The transmission electrode and the compensation electrode can be supplied with an electric switching signal of predetermined signal frequency and predetermined signal amplitude. Switching electric signal at the compensation electrode is phase-delayed with respect to the switching electric signal at the transmission electrode. Alternating electric fields radiated at the transmission electrode and the compensation electrode generate a current in the reception electrode, which is representative of an approach of a hand to the hand-held device. The transmission electrode and the reception electrode are arranged in such a way, that the impedance between the transmission electrode and the reception electrode exceeds a predetermined value, which is suitable to keep the current generated in the reception electrode under a predetermined value.
