Abstract: A light emitting diode illumination control system is disclosed for driving a current circuit for energizing one or more LED light sources. The system comprises a control system including a microprocessor arranged to control a pulse amplitude modulated (PAM) voltage controlled current circuit, and may employ a monitor for monitoring at least one ambient condition and a microprocessor operable to control the current circuit in response to the monitored condition.

Abstract: The present invention relates to a spindle motor with a magnetic seal. A method and an apparatus are described for sealing spindle motors, preferably those used for disk storage units.

Abstract: A cone-shaped outwear or disposable raingear of substantially waterproof material, having oppositely disposed front and back panels, with bottom edges, a bottom opening and sealed side edges terminating at said opening. The front panel having at least a partially perforated face opening disposed below where the side edges terminate at a top end, and at least two partially perforated openings disposed below the face opening. The method of fabricating the raincoat includes the steps of partially perforating a first elongated plastic sheet material with at least a partially perforated face opening and at least two partially perforated openings disposed below the face opening, and aligning another elongated plastic sheet material with the partially perforated plastic sheet material so that their elongated edges generally coincide with each other.
