Abstract: A method and apparatus for providing a power supply for an amplifier is provided. The power conversion is achieved using synchronous rectifiers in a regulated half bridge power supply, taking the sum of the positive and negative rails as feedback, in order facilitate energy transfer between positive and negative output rails. This minimizes the effects of off side charging and rail sag, as well as achieving good line regulation, while allowing use of very small, low value output capacitors.

Abstract: The present invention is a speed control for a cable retractor. The cable retractor with which the speed control is used comprises a pulley that engages a cable that may be extended and retracted. A friction element configured to adjustably contact the cable adjacent to the pulley is attached to a movable linkage. The movement of the linkage is constrained to move along a predetermined path such that movement of the linkage along the path alters the distance between the friction element and the pulley. In one or more embodiments a cantilevered spring is attached to the linkage. An adjustable control, for example a thumbscrew, is configured to move the spring in relation to the linkage in a manner that alters the position of the friction element with respect to the cable and/or the pressure exerted by the friction element on the cable.

Abstract: A method and apparatus for automatic compensation of insertion loss in signals transmitted over conductors is presented. The present invention is particularly applicable to the transmission of signals over long lengths of CAT-5 or similar twisted-pair cables. A reference signal having a known form and strength (e.g. a pulse signal) is provided to each pair of conductors carrying a component of a signal from a transmitter to a receiver. The receiver includes adjustable gain amplifiers for each conductor pair over which a component of the signal is transmitted. The gains of the amplifiers are initially set at an initial level (e.g., their maximum gain) to allow detection of the reference signal. Once the reference signal is detected in a conductor pair, the amplifier gains are adjusted such that the level of the reference signal is restored approximately to its original form and strength.

Abstract: A triangular waveform generator includes a square waveform clock circuit and an integrating circuit. The integration circuit receives input from the square waveform clock circuit and generates a triangular waveform output. A feedback circuit is operatively connected to the integrating circuit to reduce the audio band noise content in the triangular waveform output. The feedback circuit acts as a DC balance without significant sacrifice in the linearity of the triangular waveform output.

Abstract: This invention describes a method and apparatus for vertically locking input and output video frame rates. The output vertical sync pulse is locked in phase with the input vertical sync pulse, regardless of the input format and frequency. The output resolution, horizontal refresh rate, and delay are all user selectable. Two Phase Locked Loops are connected in series to achieve vertical lock between the input and output frames. Locking the vertical sync pulses between the input and output frames will eliminate mixing of pixels from different input frames in one output frame. The first Phase Locked Loop generates the output pixel clock required to satisfy the user's display preferences but may not precisely represent the desired output pixel clock required for frame locking because current Phase Locked Loops use integer dividers. A second Phase Locked Loop adjusts its output, which is the reference frequency to the first Phase Locked Loop, until a lock is achieved. A free running oscillator measures the frequency of the incoming video and sends its output to a micro-controller that computes the divider required in the first Phase Locked Loop based on user selected output resolution. The user may also adjust the delay between the vertical input and output video frames.

Abstract translation: 本发明描述了用于垂直锁定输入和输出视频帧速率的方法和装置。 输出垂直同步脉冲与输入垂直同步脉冲同相锁定，无论输入格式和频率如何。 输出分辨率，水平刷新率和延迟均可由用户选择。 两相锁定环串联连接，实现输入和输出帧之间的垂直锁定。 锁定输入和输出帧之间的垂直同步脉冲将消除一个输出帧中来自不同输入帧的像素的混合。 第一个锁相环产生满足用户显示首选项所需的输出像素时钟，但可能不会精确地表示帧锁定所需的输出像素时钟，因为当前锁相环使用整数分频器。 第二个锁相环调整其输出，这是第一个锁相环的参考频率，直到达到锁定为止。 自由运行的振荡器测量输入视频的频率，并将其输出发送到微控制器，该微控制器根据用户选择的输出分辨率计算第一个锁相环中所需的分频器。 用户还可以调整垂直输入和输出视频帧之间的延迟。
