US Patent:

58618422, Jan 19, 1999

Filed:

Aug 29, 1997

Appl. No.:

8/920739

Inventors:

Benjamin F. Hitch - San Jose CA
Kenneth Gilliland - Mountain View CA

Assignee:

Space Systems/Loral, Inc. - Palo Alto CA

International Classification:

G01S 502
H04B 7185

US Classification:

342357

Abstract:

An earth orbit satellite control system which provides automatic, continuous correction of phase and frequency in order to maintain synchronization between the satellite and a Global Positioning System (GPS). The system achieves phase and frequency synchronization by disciplining the satellite's reference oscillator by phase locking it to timing pulses received from the GPS. The system comprising a state machine controller which cycles the disciplined oscillator into both a closed-loop operation wherein the oscillator is phase-locked to the GPS timing pulses, and an open-loop operation wherein a previously stored GPS timing pulse, or commands from a ground station, drive oscillator phase and frequency synchronization.

Abstract:

Methods and systems for managing golf clubs and for collecting golf data, such as golf strokes, are described. In one embodiment, a golf data collection system includes a golf accessory worn on the golfer's wrist, such as a watch, equipped with a GPS receiver, impact sensing and motion sensing means, and a transceiver to communicate with golf club tags (e.g. at 2.4 GHz such as Bluetooth). The golf accessory senses the motion of the golf club being swung by the golf and/or senses the impact of the golf club striking the golf ball. When swinging motion or impact is sensed the device uses the transceiver to communicate with golf club tags. The closest golf club (i.e. the club in the golfer's hand during the swing) is captured as the club used by the swing based on RSSI (Received Signal Strength Indicator). Other embodiments are also described.
