Golf club swing analyzers
First Claim
1. A golf club swing analyzer comprising:
- a light emission device configured to emit reference light toward a swung golf club;
a light reception device configured to receive reference light emitted from the light emission device and reflected from, the swung golf club; and
discrimination circuitry coupled with the light reception device and configured to discriminate the received reference light from incidental light and to generate an indication signal responsive to the discrimination of the received reference light and the incidental light, wherein the swung golf club blocks the incidental light from being received using the light reception device and the discrimination circuitry is configured to discriminate the received reference light from the incidental light responsive to the blocking.

Abstract
According to one aspect of the present invention, a golf club swing analyzer provides a housing; a light emission device configured to emit reference light toward a location in the path of a golf club swung adjacent the housing; a light reception device supported by the housing and configured to receive reference light emitted from the light emission device and reflected from the swung golf club; and discrimination circuitry coupled with the light reception device and configured to distinguish the reflected reference light received from the light emission device from incidental light, the discrimination circuitry being further configured to generate an indication signal responsive to the reception of reflected reference light.

13. A golf club swing analyzer comprising:
-
circuitry configured to receive reference light from a swung golf club, to receive incidental light, to discriminate the received reference light from the received incidental light, and to generate an indication signal to indicate the reception of the received reference light responsive to the discrimination; and
wherein the incidental light comprises light not generated for use in analyzing a golf swing, and the discrimination circuitry is configured to discriminate the received reference light from an entirety of all present incidental light. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A golf club swing analyzer comprising:
-
a light reception device configured to receive reference light from a swung golf club and to receive incidental light;
circuitry coupled with the light reception device and configured to generate an indication signal responsive to the reception of the received reference light and not to generate the indication signal responsive to the reception of the received incidental light; and
a display coupled with the circuitry and configured to indicate detection of the swung golf club responsive to the generated indication signal; and
wherein the circuitry is configured to generate a pulse corresponding to the swung golf club blocking reception of incidental light from the light reception device, and the circuitry is configured to compare the generated pulse with the at least one pulse of the reference light to filter the incidental light. - View Dependent Claims (24, 25, 26)

27. A golf club swing analyzer comprising:
-
a housing;
a light emission device configured to emit reference light in a substantially vertical direction toward a location in a path of a golf club swung adjacent the housing;
a light reception device supported by the housing and configured to receive reference light emitted from the light emission device and reflected from the swung golf club, wherein the light emission device is configured to emit the reference light in a plurality of pulses individually having a duration less than the duration of one of the rise time and fall time resulting from the golf club blocking incidental light from the light reception device; and
discrimination circuitry coupled with the light reception device and configured to discriminate the reflected reference light received from the light emission device from incidental light by generating a timed pulse responsive to reference light being received within the light reception device, the timed pulse having a duration greater than the duration of the reference light pulses and less than an individual one of the rise time and fall time.
