Latest Patents
One of his latest patents is for a head cylinder for a recorder. This invention features a drum for a rotatable cylinder head that includes an opaque disc-shaped member with multiple opaque fins affixed to it. The fins are arranged substantially normal to the disc-shaped member, with varying widths to enhance functionality. Each fin has a distal end that is remote from the disc-shaped member, and an opaque circumferential ring is affixed to the distal end of each fin, creating a series of apertures around the drum.
Another significant patent is for a brushless DC motor system with an optically scannable member for commutation. This system includes a multi-pole DC motor equipped with coils and permanent magnets. Optically scannable markers are applied to the circumference of a rotating member in fixed association with the magnets. A scanner converts these markers into signals, which are evaluated for their phase position and moment of commutation, allowing for precise control of the commutation current supplied to the coils.
