A find it map system including: a server including a processor; and a memory in communication with the processor; the memory having a database comprising at least data related to positioning and tracking of a game ball; and a device capable of accessing GPS and including a user-interface configured to enable communication with the server via a software application. The device and software is useful for golfers.

A method for calculating the position of an athlete, referred to as target, on a sports field, including estimating an approximate position of the target using a radio-based positioning system, the system including tracking sensors attached to several athletes on the sports field and antennas installed around the sports field, defining a search space around the approximate position, detecting an athlete in the search space using an optical-based positioning system, the system including cameras installed above and/or around the sports field and image recognition device, determining an accurate position of the detected athlete, attributing the accurate position to the target.

A process to partition a video feed to segment live player activity includes receiving, on a first recurring basis, a transmission of a central video feed from a first camera. The central video feed is calibrated against a spatial region represented in at least two dimensions that is encompassed by the central video feed. The process includes receiving, on a second recurring basis, a respective time-stamped position information from each tracking device in a plurality of tracking devices. Each tracking device is worn by a corresponding subject on the spatial region and transmits positional information that describes a time-stamped position of the corresponding subject in the spatial region. The process uses the received information and the calibration to define a first sub-view of the central video feed associated with a first subject. The first sub-view comprises a corresponding sub-frame associated with the first subject.

A non-transitory computer-readable medium storing a plurality of computer-readable instructions executable by a processor, wherein execution of the instructions configures the processor to: obtain location data representing a ground path of a flight of an object; determine, from the location data, a first ground distance and a second ground distance traversed by the object during an ascent phase and a descent phase of the flight of the object, respectively; determine an initial angle of the flight of the object; determine an initial airspeed of the object based on the determined initial angle; determine an air drag value for the object during the flight based on the determined initial angle and the determined initial airspeed; output a flight path of the object, the flight path representing a three-dimensional path travelled by the object during the flight and determined based on the initial angle, the initial airspeed and the air drag value.

There is disclosed a system for local positioning. The system includes a plurality of anchors placed within a facility, the anchors in fixed positions following a calibration procedure, and a plurality of movable tags, attached to individuals and/or objects used to play a sport within the facility. A tracking server for using the plurality of anchors, in two-way-ranging communication with the plurality of movable tags, to track movement of the plurality of movable tags within the facility on an as-desired basis.

A system and method for simulating lead of a target includes a network, a simulation administrator and a user device connected to the network, a database connected to the simulation administrator, and a set of position trackers positioned at a simulator site. The user device includes a virtual or augmented reality unit and a computer connected to the network. A target may be simulated or may be a real-world object. The target and the user are tracked to generate a phantom target and a phantom halo. The phantom target and the phantom halo are displayed on the virtual or augmented reality unit at a lead distance and a drop distance from the target.

Methods, systems, and apparatus, including medium-encoded computer program products, for 3D flight tracking of objects include a method including: determining at least one three dimensional trajectory for at least one golf ball hit into a three dimensional physical space based on observations by at least one golf ball sensor placed adjacent to the three dimensional physical space; calculating systemic and stochastic errors for the at least one three dimensional trajectory in accordance with variations in golf ball launching position, variations in locations for the at least one golf ball sensor, or both; and presenting a report showing a summary of the calculated systemic and stochastic errors to indicate preferred hitting positions, a different location for the at least one golf ball sensor, or both.

System for detecting a person on an underground, which is provided with passive RFID tags (1) in a predetermined pattern, while the person is provided with a sensor module (2), which is adapted to determine the position thereof relative with respect of to the RFID tags and, preferably, the direction and/or the acceleration and/or the inclination thereof. The sensor module and/or further processing means are arranged to calculate the position of the sensor module by means of triangulation calculation. The tag pattern is formed by a regular pattern of tag clusters (4), each being formed by two tag strips, oriented in a T-shape with respect to each other. Of the T-shaped clusters, the first tag strip has an even identification code and the other tag strip has an odd Identification code. The RFID tags are applied to construction foil, which is positioned under the top layer of a floor.

Presented are intelligent electronic footwear and apparel with controller-automated features, methods for making/operating such footwear and apparel, and control systems for executing automated features of such footwear and apparel. A method for operating an intelligent electronic shoe (IES) includes receiving, e.g., via a controller through a wireless communications device from a GPS satellite service, location data of a user. The controller also receives, e.g., from a backend server-class computer or other remote computing node, location data for a target object or site, such as a virtual shoe hidden at a virtual spot. The controller retrieves or predicts path plan data including a derived route for traversing from the user's location to the target's location within a geographic area. The controller then transmits command signals to a navigation alert system mounted to the IES's shoe structure to output visual, audio, and/or tactile cues that guide the user along the derived route.
