    Abstract: The compact coin hopper for holding and dispensing coins in bulk includes a rotable disk for releasing individual coins to a sliding base beneath the rotable disk for ejection from the coin hopper. The upper surface of the rotable disk includes an upper step part and a lower step part connected by a riser part. The upper step part has a crescent arc shape with a radii smaller than the radius of the rotating disk in a planar view. One end of the crescent arc shape terminates adjacent an edge of the through hole while the other end of the crescent arc shape diverges away from the through hole and terminates adjacent a peripheral side edge of the lower step part. The configuration of the upper and lower step parts and the riser part assist in dispensing a coin.

    Abstract: Methods and apparatus to perform hard-disk drive head proximity detection in a preamplifier are described. One example method of detecting head position in a hard-disk drive includes obtaining a read signal from a head reading information from a disk; determining a signal envelope of the read signal; comparing the signal envelope to a first threshold to produce a first comparison; filtering the signal envelope; comparing the filtered signal envelope to a second threshold to produce a second comparison; combining the first comparison and the second comparison; and determining if the combination of the first comparison and the second comparison indicates head position oscillation.
