Abstract: The present invention provides a power transmission apparatus for wind power generation and a wind power generator using the same. The power transmission apparatus includes a first magnetic member which is provided around a rotating shaft of an impeller, and a second magnetic member which is provided around a rotor shaft of a generating unit. The second magnetic member is disposed at a position facing the first magnetic member such that similar poles of the first and second magnetic members face each other. Thus, when the impeller is rotated by wind, the rotor shaft of the generating unit is rotated by magnetic repulsive force between the first magnetic member and the second magnetic member. Thereby, the rotating force of the impeller is transmitted to the generating unit.

Abstract: A comparator apparatus for comparing a first and a second voltage input includes a pair of cross-coupled inverter devices, including a pull up device and a pull down device, with output nodes defined between the pull up and pull down devices. A first switching device is coupled to the first input and a second switching device is coupled to the second input, with control circuitry configured for selective switching between a reset mode and a compare mode. In the reset mode, the first and second voltage inputs are coupled to respective output nodes so as to develop a differential signal thereacross, and the pull down devices in each inverter are isolated from the pull up devices. In the compare mode, the voltage inputs are isolated from the output nodes, and the pull down devices in each inverter are coupled to the pull up devices to latch the output nodes.
