US Patent:

6496549, Dec 17, 2002

Filed:

Jul 13, 1999

Appl. No.:

09/352428

Inventors:

Richard D. Crawford - Los Altos CA

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

H03D 124

US Classification:

375320, 327 18, 329347

Abstract:

An approved demodulator is disclosed for demodulating optical ASK data signals whose data bits are each characterized by either an absence of pulses or a burst of pulses at a predetermined frequency. The demodulator includes an amplifier tuned to this predetermined frequency, and it further includes an edge detector that produces an envelope of the amplified signal. A comparator then compares the envelope signal with a prescribed threshold, to produce a pulse signal for each received burst of pulses. The duration of this pulse signal is then stretched so as to correspond to the pulse bursts expected nominal duration. The demodulator is specially configured such that it can properly demodulate ASK data signals having power levels that vary over a range of several orders of magnitude.

Appl. No.:

10/698898

Inventors:

Richard Crawford - Los Altos CA, US

International Classification:

H04B003/00

US Classification:

375257000

Abstract:

An interface routes power and digital signals to a load. The interface includes a rectifier receiving the power and the digital signals over a single wire pair and producing rectified power and rectified digital signals, and a separator for separating the rectified power driving the load from the rectified digital signals controlling output of the load.

International Classification:

G06F 1/16

Abstract:

Magnetic force adjustment mechanisms are described herein. An electronic device includes a base, a first magnet carried by the base, a lid and a second magnet carried by the lid. The first and second magnets secure the base and the lid together with a holding force. A hinge pivotally couples the lid and the base. A slider displaces at least one of the first or second magnets relative to the other of the first or second magnets to reduce the holding force.
