Latest Patents

One of Sandro Cerato's latest patents is a "Feedforward circuit and method for controlling the speed of a spindle." This invention is utilized in disk drives and features a feedforward circuit that connects the head position circuit to the speed control loop circuit. The feedforward circuit is designed to precompensate the speed control loop for variations in rotation drag caused by movements in the disk drive's head. Additionally, the circuit may include one or more deadband amplifiers and a filter circuit. The method disclosed in this patent involves controlling the speed of a spindle motor by precompensating the speed control loop circuit with a processed head positioning signal.

Another significant patent is for an "IC controlled DC motor." This invention describes a DC motor that includes a housing, a hub member rotatably supported by the housing, and a flexible printed circuit board that is fixedly mounted on the housing. An IC chip is mounted on the flexible printed circuit board, positioned to face a recess formed in the housing. The hub member features a shaft that is rotatably supported by a bearing within the recess. The flexible printed circuit board contains a metal layer for mounting the IC chip, which is isolated from the wiring pattern on the printed circuit board.
