Abstract: A probe monitoring system for riverbed elevation monitoring at bridge piers is revealed. The system includes a housing, a measuring rod, a moving member, a control module, a photographic unit and a sensing unit. The housing is fixed on the pier. Both the moving member for driving the measuring rod and the control module for control of the moving member are mounted in the housing. When the control module drives the measuring rod to move downward and the sensing unit on the bottom of the measuring rod approaches the riverbed, a sensing signal is sent to the control module. Thus the moving member stops moving the measuring rod and the photographic unit takes pictures of the measuring rod to generate an image. Then the riverbed elevation is obtained according to the image or the movement of the moving member and is sent to a remote monitor unit for real-time monitoring.
Abstract: A control circuit and method are proposed to generate a control signal to operate a buck-boost power stage of a buck-boost power converter to convert an input voltage to an output voltage. The control circuit and method detect the output voltage to generate an error signal, control the frequency of two ramp signals according to the error signal, generate two pulse width modulation signals according to the error signal and the two ramp signals, and generate the control signal according to the two pulse width modulation signals. When the loading of the buck-boost power converter transits from heavy to light, the frequency of the two ramp signals is decreased to improve the efficiency of the buck-boost power converter. The peaks and valleys of the two ramp signals may be adjusted by signals related to the input voltage and the output voltage.

Abstract: An improved structure of three-dimensional (3D) spectacles is provided, including a spectacle frame on which an RFID (Radio Frequency Identification) chip is mounted. The 3D spectacles are specifically for use in a 3D auditorium or 3D theater and are composed of a frame, lenses, and temples. The RFID chip is combined with the spectacle frame by being embedded in the frame or attached to a surface of the frame. With the RFID chip so mounted, a theater worker may use a reader to identify if a specific pair of 3D spectacles has already been sanitized. Also, the 3D spectacles can help in entrance and exit management, ticketing management, distribution of souvenirs, and toilet guiding service. In file-out, a reader may be used to confirm the returning of 3D spectacles. In this way, the theater service quality can be significantly improved.

Abstract: A treadmill roller structure comprises a motor, a gear set and a case. The motor is an out-runner motor. The power output section of the motor rotates about stationary spindle. The rotary power output section is engaged to the gear set, while the gear set is in turn engaged to the case, thus allowing the case to rotate relatively to the spindle of the motor as well. The roller structure does not require a driving belt to transfer power from the motor to the roller, thus reduces the power loss due to frictional force during power transfer through belt driving, which enhances the performance of the motor and offers a space-saving feature. In addition, the instant disclosure also provides a treadmill.
