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 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.
