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.

Abstract: Apparatuses, methods and systems related to an improved golf data collecting and golf club notification system. The system reminds golfers when a club has been mistakenly left behind on the golf course and notifies the golfer when a golf club or clubs are in or out of the golf bag. The system can notify a golfer if a club or golf bag has been removed without authorization. In one preferred embodiment an apparatus that attaches to a golf club includes dual light sensors—one light sensor configured as a switch and one light sensor configured as a light meter. Algorithms make use of the light sensor data to determine whether a golf club is in or out of a golf bag.

Abstract: Golf balls and a system for finding golf balls and methods for making golf balls and methods for using such balls. In the case of one exemplary golf ball, the ball includes a shell and a core material which is encased in the shell and a tag which is disposed within the core material and which has at least one perforation. The tag includes a diode and an antenna which are coupled together. Another exemplary golf ball includes a shell and a core material which is encased within the shell and a tag which is within the core material and which includes an electrical element which is coupled to an antenna; the tag is detectable over a range of at least 20 feet from a handheld device, and the golf ball has high durability and substantially complies with the golf ball specifications of the United States Golf Association.

Abstract: Apparatuses, methods and systems relating to at least one or more of golf club reminding and golf data collecting and recording. In one embodiment an apparatus on a golf club includes an integrated reminder and a stroke cancellation system and is semi-automatic in that the recording of the stroke is directly in response to changing the state (e.g. activating) of a switch which indicates that the golfer has pressed a button on the golf club. The pressing of the button indicates that the golfer will or has taken a stroke with the golf club and that the stroke is to be recorded, with the location of the stroke and an identifier of the club (e.g. 9 iron). The system may also be equipped with a missing club reminder and theft prevention function that notifies the golfer is a golf club has been left behind or if a club or golf bag has been removed without authorization.

Abstract: Methods, apparatuses, machine readable non-transitory storage media, and systems which process measured light values in order to determine the status of a golf club relative to a golf club bag are described. In one embodiment, a system uses a floating threshold, which is between a running bright average and a running dark average, to determine whether to add a current light meter value to one or the other of these running averages. In another embodiment, a system resets or re-seeds the running averages so that re-seeded averages are used after exiting from a sleep state such as a dark sleep state. In another embodiment, a system uses light sensor information or other sensor information to determine when a club is in use. Other embodiments are also described.

Abstract: Golf ball locators and components of such locators and methods of operating such locators and processing signals within such locators. In one aspect of the inventions described herein, an exemplary method of initializing a golf ball locator includes receiving received RF signals while also transmitting signals used to locate balls and determining a parameter representative of received signal strength of the received RF signals and setting a threshold to determine when subsequent received signals are to cause an indication of golf ball detection. In another aspect of this disclosure, the golf ball locator is a handheld unit having a volume of less than about 150 inches cubed and includes a transmitter, a transmit antenna, a receiver, a receive antenna and a processor coupled to the transmitter and to the receiver, and the handheld unit achieves a signal isolation, between a second harmonic of a transmitted signal from the transmitter and the receiver's received signal, of greater than about 130 to 160 dB.
