    摘要: The present invention introduces methods and circuits to amplify audio signals for driving speakers. An additional feedback circuit is added in an audio amplifier to couple the amplifier stage and output stage of the audio amplifier. The feedback circuit turned off as long as output voltages of the audio amplifier are not near saturation. The feedback circuit is turned on to reduce audible noises if output voltages of the audio amplifier are near saturation.

    摘要: An automated animal feeder is disclosed having a storage area with a top at one end and the second feeding into a dispensing module containing a dispensing tube. An auger, connected to a support and motor, extends into the second opening of the storage area. Preferably the auger support is movable along the dispensing module to vary a distance between the length of the auger at the proximal opening of the dispensing tube. A programmable control panel controls the motor and can have a display screen, speaker and programming members, or the control panel can be controlled by remote control. Power can be from at least one from the group of replaceable battery, rechargeable battery, solar or electricity, power the control panel and motor. A deflection tab extends into the dispensing tube, spaced from the auger, to prevent the accumulation food on the auger. The hanging member on the top can affixed to a stand with a post having a first end, a second end and a pivot point, the pivot point being affixed to the stand. The first end has a connection member for the hanging member and said second end has a rotation prevention member and an anchor. The post can rotate upon the release of the anchor to a predetermined distance from the ground as determined by the rotation prevention member or be locked in an upright position by said anchor.

    摘要: The described DC to AC inverter efficiently controls the amount of electrical power used to drive a cold cathode fluorescent lamp (CCFL). The output is a fairly pure sine wave which is proportional to an input control voltage. The output waveform purity is ensured by driving a symmetrical rectangular waveform into a second-order, low pass filter at the resonant frequency of the filter for all conditions of line voltage and delivered power. Operating stress on the step-up transformer is minimized by placing the load (lamp) directly across the secondary side of the transformer. When configured to regulate delivered power, the secondary side may be fully floated which practically eliminates a thermometer effect on the operation of the lamp. All of the active elements, including the power switches, may be integrated into a monolithic silicon circuit.
