Abstract: A physiology detecting garment is provided in the invention. The physiology detecting garment includes a garment, a first transmission line, a second transmission line, a first detecting device, a second detecting device, a first textile antenna and a second textile antenna. The first textile antenna is configured in the garment and receives a first sensing signal. The second textile antenna is configured in the garment and receives a second sensing signal. The first detecting device samples the first sensing signal to generate a first time index and the second detecting device samples the second sensing signal to generate a feedback signal. The first detecting device generates a second time index according to the feedback signal, and generates a time parameter according to the first time index and the second time index, and obtains physiological information according to the time parameter.

Abstract: A pulse radar ranging apparatus and a ranging algorithm thereof are provided. The pulse radar ranging apparatus includes a radio frequency pulse generator, a radio frequency filter, a radio frequency switch and a transceiver aerial. The radio frequency pulse generator generates a pulse signal. The radio frequency filter receives the pulse signal and generates a high-pass filter signal, wherein the high-pass filter signal includes a radio frequency pulse reference signal. The radio frequency switch controls an output of the radio frequency pulse reference signal. The transceiver aerial transmits the radio frequency pulse reference signal. The radio frequency pulse reference signal contacts an object and generates a return signal, and the transceiver aerial receives the return signal. The ranging algorithm processes and analyzes the signals obtained by the pulse radar ranging apparatus, and calculates a distance between pulse radar ranging apparatus and the object by using polynomial interpolation.

Abstract: A portable cushion device is provided, including a first cushion region, a second cushion region, a control interface module, and an alarm unit. The second cushion region includes an inflation inlet. The first cushion region is located on the outside of the second cushion region. The control interface module is connected to the second cushion region, and is able to inflate the second cushion region to a specific pressure through the inflation inlet. When an object is placed on the second cushion region, the control interface module measures the weight of the object and monitors the object continuously. The alarm unit is triggered to issue an alarm when the control interface module detects a sudden increase or decrease of the weight of the monitored object on the second cushion region.

Abstract: A DC frequency modulation circuit for modulating audio signals wherein the high frequencies of the audio signals are modulated by a first phase locked loop and the low frequencies of the audio signals, along with the DC signals, are filtered by a low pass filter, applied through an A/D converter, and modulated by a direct digital frequency synthesizer. The two modulated signals are then mixed by a second phase locked loop.
