    摘要: An operation method and a radio device for controlling a power switch of a radio based on moving speed. The radio device includes a speed estimator and an operator. The speed estimator is used for estimating the moving speed of the radio device, and the operator is used for comparing the moving speed of the radio device with a speed threshold value so as to turn on/off the power switch of the radio device. The power switch of the radio device can be controlled based on the moving speed so as to decrease the time the radio device stays on, thus reducing the power consumption of the radio device.

    摘要: The present invention relates to a system, and a method for time synchronization with low power consumption and high accuracy. The system comprises a plurality of devices for time synchronization. Each device comprises a GPS receiver, a microprocessor, and an oscillator. The microprocessor generates a drift per second according to the difference between the PPS signal and the clock signal, and calibrates the clock signal constantly according to drift per second. The GPS receiver is turned off when the drift per second is obtained, and then is turned on after a pre-determined time period for updating the drift per second.

    摘要: A method for inviting a challenged entity to provide input concerning a sinograph includes displaying, to the challenged entity, a first region having an image of a challenge sinograph; displaying at least a first event-sensitive region, the first event-sensitive region having an image of a real root of the challenge sinograph; and displaying at least a second event-sensitive region. The second event sensitive region has an image of a faux root of the challenge sinograph.
