A sports object comprises an electronic circuit having a power source and a transmitter and arranged to transmit a signal identifying the sports object. The sports object has an inner core encapsulating the electronic circuit. The inner core is configured such that the inner core and electronic circuit are balanced. There is at least one outer core layer encapsulating the inner core. The sports object is used in a system for providing sports game information. The system comprises the sports object and a portable computing device including a receiver responsive to the signal and a location means for determining the location of the computing device. The computing device records the signal received at two or more different locations and records the location of the computing device at each of the different locations to enable estimation of a location for the sports object identified by the received signal.

A sensor device includes at least one processor configured to execute processing including: communicating with a user terminal serving as a communication device, acquiring a current position by using prediction ephemeris, acquiring the prediction ephemeris from the user terminal, storing position information indicating the current position acquired, repeating, at intervals, acquiring communication device position information indicating the position of the user terminal and updating the position information based on the communication device position information, and shortening the interval for acquiring the communication device position information when a discrepancy, between the communication device position information and the stored position information prior to being updated is larger than a prescribed reference.

The disclosure herein provides a smart golf pin system and golf GPS device with a mechanism to automatically receive golf hole cup information and display the golf hole information on the golf GPS device. More specifically, the golf GPS device receives data from a plurality of GPS modules installed on the golf pins located throughout the golf course and based on its current location, selects a set of GPS coordinates corresponding to the current hole that the golfer is playing, and displays a distance from the golf GPS device to the actual hole cup location in the current hole, thereby allowing the golfer to fine tune his or her approach accordingly.

Embodiments are disclosed to calculate and store rock climbing navigational data using a rock climbing watch including a sensor array configured to measure an orientation of the rock climbing watch and a processor configured to calculate an angle between two rock face locations along a rock climbing route based upon an orientation of the rock climbing watch when it is pointed from a current rock face location towards another rock face location. A processor may determine route segments for traversing the rock climbing route. A processor may convert route climbing navigational data into a three-dimensional wireframe rock climbing navigational map including rock face locations, calculated distances and angles between rock face locations, and a rock climbing route. The rock climbing watch may present information to guide the user along a rock climbing route by displaying a graphical directional indicator and a distance to the next rock face location.

Techniques for music selection based on exercise detection are disclosed. In one aspect, a method of operating a wearable device may involve determining, based on output of one or more biometric sensors, that a user of the wearable device has started an exercise and playing music for the user of the wearable device in response to determining the start of the exercise. For example, playing the music may involve turning on a music player based on the start of the exercise. In another example, the wearable device includes the music player.

Systems and methods providing statistical analytics of golf performance for coaching including text, tabular, graphic, and image-based outputs that include trends information for the golfer, all based upon actual golf play on course situations, wherein the golfer inputs shot data during play, without interrupting the flow of the game, and uploads the shot data for analytics and review online, and wherein all information related to a given user are reviewable by an authorized coach user through a web-based coach access account. The system is further operable to provide the coach user rights for providing corrective or instructive feedback to the user, including visual recommendations such as modified target areas.
