Methods, systems, and apparatus, including medium-encoded computer program products, for 3D flight tracking of objects include a method including determining a golf ball trajectory based on observations by sensor(s), extrapolating the trajectory backward in time, calculating distance measure(s) between the extrapolated trajectory and physical locations, estimating a systemic error for observation(s), wherein the systemic error affects observed ball positions, estimating a stochastic error associated with the observation(s), wherein the stochastic error affects an angle of a trajectory determined from observed ball positions, combining the estimated systemic and stochastic errors to form error measure(s) for the distance measure(s), identifying one of the physical locations as an origin for the golf ball when the error measure(s) satisfy a criterion, and waiting for additional observations of the golf ball by the sensor(s) when the error measure(s) do not satisfy the criterion.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

There is provided an information processing device, an information processing method, and a computer program capable of more reliably recognizing positions of a plurality of detection targets. The information processing device includes a control unit for recognizing positions of a first detection target and a second detection target that are present on the same surface. The control unit recognizes the position of the first detection target based on sensing data obtained by a first sensor for sensing the first detection target from a first direction, and recognizes the position of the second detection target based on sensing data obtained by a second sensor for sensing the second detection target from a direction opposite to the first direction across the same surface.

There is provided a limb exercise device comprising: a force sensor configured to determine a weight applied to the device; a sliding component configured to facilitate the sliding movement of the device along a separate surface, wherein the separate surface is a surface that is separate to the device, wherein the sliding component comprises a part of an external housing of the device; a device movement sensor configured to determine a movement of the device on the separate surface; a limb position sensor configured to determine a position, in at least one dimension, of a limb of a user positioned above or adjacent to the device; and an output device configured to output an indication in dependence on a signal from at least one of: the force sensor, the device movement sensor and the limb position sensor.

Systems and methods for identifying golf equipment. The system may include one or more performance tracking devices, such as an optical sensor system or a radar sensor system for tracking at least one of a golf club swing or a golf ball flight. The system also may include at least one processor and memory storing instructions that, when executed by the at least one processor, cause the system to perform a set of operations. The operations include receiving current dynamic input for a golf shot from a golfer and current static input for the golfer. The operations also include executing a trained machine-learning model based on the received current dynamic input and current static input to generate predicted golf club properties and/or predicted golf ball properties for the golfer. The predicted golf club properties and/or predicted golf ball properties are displayed on a connected display.

A shoe includes: a heel portion; a toe portion; a sole portion; and an electrical assembly. The electrical assembly includes at least: a magnetometer configured to determine a direction of movement of the shoe; and an accelerometer configured to determine acceleration of the shoe. Direction and acceleration data are used to generate a display of a map indicating traversal of a route by a wearer of the shoe at user interface of a user device.

Systems, methods and computer-readable media are provided for determining an effective altitude in relation to a moving sports object. In some examples, a method includes determining respective values for an air temperature, an air pressure, and a relative humidity of an environment of interest. Based on the determined respective values of the air temperature, the air pressure, and the relative humidity, an air density for the environment of interest is calculated to derive a first air density value. A second air density value is derived for a reference environment. An absolute value of a difference between the first and second air densities is compared against a preset comparison value and, based on the comparison being equal to or smaller than the preset comparison value, an output including an indicator of the effective altitude is generated.

A ground traversing, electrically driven drone travels along a programmed path that corresponds to pass catcher's travel path during a play, matching the pass catcher's speed and run cuts. The play is wirelessly communicated to the drone by a handheld electronic device located remote of the drone. A target is located on the drone so that a quarterback can throw a football at the target in order to refine the quarterback's timing and accuracy for the play. Sensors located remote of the drone track both the football's and quarterback's speed and travel trajectories so that such data can be collected, along with the drone's travel path, and transmitted to the computer and eventually fed into 3-D reconstruction software for analysis by the quarterback and coaching staff. The target rotates so that the target either faces in a fixed direction or constantly faces the quarterback during execution of drone's maneuvers.

System and method for a golf cart to automatically proceed to the location of a struck golf ball. The system and method allow a golfer to play golf without the need to keep diligent track of the ball. The golf cart determines the location of the struck ball and the proceeds to the location of the ball. This reduces the time needed to find a struck ball and reduces the instances of lost balls.

A scoring system is disclosed for a shuffleboard table 2 having a sliding surface 4 on which a puck 6 can be thrown. A camera 26 is arranged to point in a direction 28 that is angled relative to the normal 30 of the sliding surface 4. A puck 6 can be thrown and a computer 32 can detect a moving object within a throwing zone 16. The computer 32 analyses whether the detected moving object corresponds to a valid puck. When all pucks are stationary on the sliding surface 4 the computer 32 can calculate a score.
