A basketball shot counter includes a mounting shaped and sized to connect the basketball shot counter to a portion of a basketball goal having a basketball hoop; a vibration sensor; a processor in data communication with the vibration sensor, wherein the processor is configured to receive, from the vibration sensor, a datastream of vibration sensor readings; determine, from the datastream of vibration sensor readings, that a first basketball shot was attempted without successfully going through the basketball hoop; and determine, from the datastream of vibration sensor readings, that a second basketball shot was attempted and successfully went through the basketball hoop.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A system for illustrating the flight of a sports ball includes a radar, an imager, and a controller. The imager is configured to image a moving sports ball. The controller is configured to (i) receive, from the imager, an image including the moving sports ball, (ii) receive, from the radar, radar data associated with the moving sports ball, (iii) determine, from the radar data, a portion of a trajectory of the moving sports ball, (iv) alter the image to illustrate the portion of the trajectory relative to the moving sports ball, and (v) output the altered image.

It is disclosed a method, and a system (30) capable of localizing ball hit events on a sports court. From on acoustics data acquired (22) of ball hit events by individual distributed sensors or microphones, ball hitting patterns are identified (24) in the data from each individual sensor. Based on the identified ball hitting patterns and geometric constraints of a sports court and the distribution of sensors, ball hit events are detected (26). The localization of the detected ball bit events is determined (28) based on the geometrical constraints of the sports court and the sensor distribution. The system has a number of advantages of which some are that it is cheap to install, it is non-invasive, and that it can easily be extended to provide higher precision of ball hit event localization.

We generally describe an audio-based line fault detection system for a sports game. The audio-based line fault detection system comprises one or more audio sensors (102) for sensing an audio signal generated by a sports gaming device bouncing off a sports field. The sports field comprises surface modifications applied to a line and/or an area adjacent to the line on the sports field such that the generated audio signal is dependent on whether or not the sports gaming device bounces off the sports field where the surface modifications are applied. The detection system is configured to generate a sound profile from the audio signal sensed by the one or more audio sensors (102). The detection system is further configured to identify a bounce type based on the sound profile, wherein the bounce type is defined by whether or not the sports gaming device has bounced off the sports field where the surface modifications are applied.

Protective headgear includes, for example, a headgear body that is wearable on a head of a baseball umpire. At least one sensor is configured to generate imaging data that includes a batter in proximity to home plate. A processor analyzes the imaging data to determine a strike zone of the batter and to generate augmented reality data in response thereto. A display device generates a heads up display of the strike zone that is viewable to the baseball umpire during a pitch to the batter, based on the augmented reality data. Other embodiments are disclosed.

The two-part system includes a modified hockey puck and a set of goal units that can be mounted on a hockey goal. Within the puck are light sources, motion sensors, infrared'transmitters, and a power source. Within the goal units are light sources, infrared sensors, and a microcontroller. When the goal units are mounted on the hockey goal, the infrared sensors form a detection area through which the puck must pass in order to count as a goal. The infrared transmitter of the puck and the infrared sensors of the goal units communicate with one another, and when an infrared signal is received the microcontroller triggers the light sources mounted to the goal to illuminate and indicate that a goal has been scored. Additionally, both the puck and the goal units are designed to reduce power consumption by switching between a low-energy mode or an active mode of operation.

The present invention comprises a unique system and method for providing adaptable ball delivery and tracking, including appropriate sensor hardware, interactive gameplay user interfaces and point of sales systems. The system and method of the present invention are especially relevant to baseball and softball as, among other components, the system comprises a vertical, ground-up soft toss ball delivery mechanism, automated player and ball-tracking devices, and ball-collection and transport systems. The ball collection and return components eliminate the need for “fielders” and enable the creation of the first “batting range”. The vertical, ground-up soft-toss pitch machine further enables the first multi-story batting facility with player batting bays that open onto a sports field. Further, certain embodiments of the present invention integrate hitting screens, augmented reality display and simultaneous coordination of gameplay and communication between players, regardless of the players' physical location.

Examples are disclosed to track sport implements and/or objects of interest. An example apparatus includes a first coil to generate a first magnetic field having a first vertical component with a zero magnitude along a first line of interest and a second coil partially overlapped with the first coil, where the second coil is to generate a second magnetic field. The example apparatus also includes a sensor to measure a magnitude of the first magnetic field in the first line of interest and a processor to determine an object of interest has crossed the first line of interest based on the magnitude of the first magnetic field measured by the sensor.

The present invention provides a tennis training device used for tennis training with a tennis trainer, comprising a batting component and a rebounding net component which can be separated. The batting component comprises an adjustable bracket group and a batting cloth connected to the bracket group. An upper end of the batting cloth is provided with a ball receiving barrel and a ball guiding tube connected with the ball receiving barrel. Protecting nets are arranged on both sides of the batting cloth. The rebounding net component comprises a supporting rod and a rebounding net plate movably arranged on the supporting rod. The tennis training device further comprises a controller, and a microphone and an LED lamp which are connected with the controller. When the tennis trainer is training, the microphone and the LED lamp provide sound and light to increase the interest of the tennis trainer during training. The present invention also provides a tennis training system which conducts training information interaction with the tennis trainer through the above tennis training device. The tennis training device has the attributes of amusement equipment, is connected with an application program on a mobile device and expands the entertainment function of the tennis training device.
