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 method and system to compute the dose to a patient (2) given a captured integrated exit-transit image (5) of the radiation rays (4) traveling from the source of x-rays (1) through the patient (2) to the imaging device (3) to product the exit-transit image (5). Each radiation field image (5) is transformed (6,8,10,12) to multiple images (7,9,11,13) for each phantom thickness (26) that was measured with the imaging device (3) for a range of field sizes (21). Given the water equivalent path (22) through the patient for a ray (4) reaching a pixel (15, 16), the final pixel value (19) is interpolated from the images (9, 11) that bracket the water equivalent path through the patient (22).

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.

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 switching controller for power converter comprises a current-sense circuit and a PWM circuit. The current-sense circuit receives high-voltage signal across a first switch to generate a current-sense signal. The PWM circuit generates a switching signal to control the first switch in response to the current-sense signal. The switching controller further comprises a delay circuit. The delay circuit receives the switching signal to generate a delayed switching signal. The current-sense signal and the high-voltage signal ramp up with the same slope during the delayed switching signal is enabled. The current-sense signal will be pulled down to a level of a ground reference during the delayed switching signal is disabled. A delay time provided by the delay circuit avoids the high-voltage signal at the instance which the first switch is being turned off being conducted to a first comparator and a second comparator via a second switch.
