A basketball performance monitoring system comprising a local microprocessor in communication with a remote computational system. At least one sensor is coupled to the microprocessor. The at least one sensor is coupled to a basketball goal and is configured to sense at least one of an attempt to score a goal and a successful goal. A first display is coupled to the microprocessor and a second display is coupled to the remote computational system.

A basketball performance monitoring system sensor comprising a sensor housing coupled to a basketball goal proximate a net. The housing has a first end and a second end opposite the first end. The housing includes an arm proximate the second end and is configured extendable inside the net. A U-shaped appendage is located between the first end and the second end. The U-shaped appendage is configured to couple to the net; wherein the sensor is configured to sense a ball impact vibration and/or an angular orientation responsive to a basketball passing over the arm.

A training device for baseball and other sports includes layers for detecting different zones of contact. The device can detect position of impact and the velocity of impact of an object such as a baseball, lacrosse ball or hockey puck by a change in voltage due to the compression or pressuring of an interlayer positioned between two conductors. The device is used for individual training as well as for competition over a network.

We generally describe a detection system and a method for tracking a moving object. The detection system (101) comprises a sensor (102) which is configured to sense an event. The system further comprises a trigger detection module (108a) which is coupled to the sensor (102), wherein the trigger detection module (108a) is configured to identify the sensed event to be a trigger event. The system further comprises an imaging device (114) for imaging the trajectory of an object, and an imaging device control unit (112) for controlling the imaging device (114). The imaging device control unit (112) is coupled to the trigger detection module (180a), wherein the imaging device control unit (112) is configured to control the imaging device (114) in response to a trigger event being identified by the trigger detection module (108a). The imaging device (114) is coupled to the imaging device control unit (112) for providing a feedback from the imaging device (114) to the imaging device control unit (112), wherein the controlling of the imaging device (114) by the imaging device control unit (112) is responsive to the feedback.

Sport training apparatus (10) for improving the speed and skill of a user such as a footballer includes a plurality of target assemblies (12), each target assembly (12) including at least one target (14). Each target (14) includes a target member (16), an alert device (17) and a sensor (20). The apparatus (10) includes a controller (22) in signal communication with each alert device (17) and each sensor (20), the controller (22) including a sequencer (24) which controls the sequence in which the alert devices (17) are activated. The apparatus (10) is arranged so that in use, one alert device (17) is activated until the respective sensor (20) detects that the respective target member (16) has been hit, whereupon the sequencer (24) will deactivate the one alert device (17) and activate another alert device (17).

A system simultaneously tracks multiple objects. All or a subset of the objects includes a wireless receiver and a transmitter for providing an output. The system includes one or more wireless transmitters that send commands to the wireless receivers of the multiple objects instructing different subsets of the multiple objects to output (via their respective transmitter) at different times. The system also includes object sensors that receive output from the transmitters of the multiple objects and a computer system in communication with the object sensors. The computer system calculates locations of the multiple objects based on the sensed output from the multiple objects.
