Method for and device controlling screen backlight unit switch of portable electronic device

The invention provides a method for controlling the switching of a screen backlight unit for a portable electronic device, and a device thereof. When a system starts in the electronic device, if a microprocessing unit judges that no arbitrary key is touched, the system enters the power-saving mode, and the screen backlight unit is cut off; if the microprocessing unit judges that the arbitrary key is touched, the system enters the operation mode, and the screen backlight unit is continued to be lit up; then the microprocessing unit judges whether the stand-by time of the device exceeds the threshold value or not, and if the stand-by time of the device does not exceed the threshold value, the screen backlight unit is continued to be lit up; if the stand-by time of the device exceeds the threshold value, an image acquisition unit is started to acquire an image positioned in front of the image acquisition unit, and if the face characteristics exist in the image by the algorithm, the screen backlight unit of the screen is continued to be lit up; and if no face characteristic exists in the image by judgement, the system enters the power-saving mode, the screen backlight unit of the screen is close to reduce the power consumption.

Elder fall-down intelligent detection and positioning active and passive alarm system and method

The invention discloses an elder fall-down intelligent detection and positioning active and passive alarm system and method, and mainly solves the problems in the prior art that detection efficiency and accuracy are low and automatic alarm cannot be performed. The system comprises an elder fall-down detection module (1), a cloud server (2) and a client side (3). The elder fall-down detection module (1) is arranged at the waist part of an elder to acquire state data including position information and safety information and intermittently transmit the state data to the cloud server (2) or transmit the state data to the client side (3) in a point-to-point way. The cloud server receives the state data of the elder fall-down detector to store in a database and transmits the state data to the corresponding client side according to the control command of the client side. The client side transmits the control command to the cloud server or the elder fall-down detector and receives and processes the feedback state data. The success rate of fall-down detection is high, automatic alarm can be performed and short messages and a data network can be simultaneously used for communication so that stability is high, and the system and the method can be used for solving elder lost and fall-down rescue.
