US Patent:

6196932, Mar 6, 2001

Filed:

Sep 8, 1997

Appl. No.:

8/925234

Inventors:

Donald James Marsh - Dennis MA
Andrew John Marsh - Needham MA

International Classification:

A63B 5700
A63B 6936

US Classification:

473223

Abstract:

An instrumented sports apparatus includes a closely spaced array of discrete sensor elements coupled to a contact surface thereof for converting a contact force between the contact surface and an object into a plurality of discrete output signals. The signals are processed and information based thereon generated, which is representative of one or more parameters of interest. In an exemplary embodiment, as instrumented golf club displays information such as club head speed, club head angle, and club head elevation upon impact with a golf ball, permitting the golfer to adjust his swing on the next stroke. Since the instrumentation and display are entirely self-contained in the club, a golfer is not constrained in the use of the club and may enjoy the benefits thereof during play on a golf course.

Abstract:

A subscriber line circuit which truly implements all of the BORSCHT functions and which does not rely on an external ringing generator to provide the ringing voltage when needed is disclosed. This implementation is achieved by recognizing that supervisory and ringing signals occur in some sort of sequence and, therefore, do not have to be generated simultaneously. Based on this recognition, we provide a circuit which truly implements all of the BORSCHT functions and includes a power section that generates each of the supervisory signals, e. g. , -48 volts and -24 volts, and alerting signal, e. g. , ringing signal, in turn and as required.
