A therapy and physical training system, comprising one or more movement sensors each of which positioned on a corresponding body part of a user, a first computer on a processor of which an application is running and a head mounted housing which is configured with a display on which images generated by the first computer are visible to the user. The application is configured to receive inputs from each of the sensors or from a second computer in data communication with each of the sensors, the application also configured to generate, in response to a real-time disposition of each of the corresponding body parts during performance of an exercise related body movement, a virtual reality object viewable by the user, the object being indicative of an additional body movement to be made by the user in order to conform with a user-specific exercise program.

A basketball training assembly includes a cart that is rollable along a support surface. The cart can be positioned a selected distance from a basketball hoop on a basketball court. A lift is coupled to and extends upwardly from the cart. The lift is turned on to extend a predetermined distance upwardly from a home position on the cart. A barrier is coupled to the lift and the lift lifts the barrier the predetermined distance from the home position when the lift is turned on to simulates a defensive basketball player. A plurality of motion sensors is each coupled to the barrier to sense motion of a basketball player approaching the barrier. The lift is turned on when one or more of the motion sensors senses motion. Thus, the lift lifts the barrier when the basketball player approaches the barrier to take a shot during basketball practice.

Methods, systems, and techniques for automated detection of goals and announcement of same are provided. The 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 automatically triggers one or more annunciator devices, such as visual, auditory, or haptic devices, to automatically indicate that a goal has been scored without human intervention.

The invention relates to a control device for controlling an engine driven transport apparatus. The control device comprises a fitness apparatus having a base part and at least one movable part movable with respect to the base part for enabling a user to perform a physical exercise. The control device further comprises a sensor device for sensing a degree of physical exercise. The control device is arranged for controlling engine power of an engine of the transport apparatus at least partly based on the sensed degree of physical exercise. The fitness apparatus comprises a flywheel rotatably connected to the base part. The fitness apparatus is arranged for setting the flywheel into motion by means of at least one of the one or multiple movable parts. The sensor device is arranged to sense the degree of performed physical exercise at least partly by sensing a degree of motion of the flywheel.

The present disclosure provides a heads up display (HUD) system configured for use with a pair of swimming goggles comprising first and second eye cups, a nose bridge connected to inner sides of the eye cups, and strap mounting portions on outer sides of the eye cups. The HUD system comprises an electronics and optics modules. The electronics module comprises a water tight housing and a processor, memory, power supply, sensors and a display within the water tight housing. The processor processes signals from the sensors to determine swimming performance data and controls the display to generate an image containing the swimming performance data. The optics module is mounted on one of the eye cups and is coupled to the electronics module for receiving the image from the display. The optics module extends from the electronics module and has one or more light directing features for redirecting the image toward an eye of a user to generate a redirected image.

A system for imparting a variable user force to a user, the system comprising: a line guide arrangement, including at least one moveable line guide which may move in both directions along a linear axis; wherein a force arrangement is arranged to apply at least one internal force to the at least one moveable line guide, wherein the at least one internal force opposes the motion of the at least one moveable line guide in a first direction along the linear axis; a member with which the user may interact so that the user force is applied to the user through the member; a line, having a distal end and a proximal end, with the distal end of the line attached to the member, the line being continuously threaded around the line guide arrangement; the system further comprising a line adjustment arrangement, wherein: the line adjustment arrangement is attached to the line, or is connected to move a component of the line guide arrangement; when the line adjustment arrangement is in a locked mode, there is a first ratio between distance moved by the member and distance moved by the force arrangement; and the line adjustment arrangement is operable to remove/introduce line between an entry point and the member, or actively move the component of the line guide arrangement, to alter the ratio between distance moved by the member and distance moved by the force arrangement during movement of the member.

A system and method for using a body joystick to interact with a virtual or mixed-reality machines or software applications that uses a support arm to hold a device for attaching the body joystick to a user's body, a sensor for detecting movement, and a tether and actuator for providing feedback to the user about interactions with the virtual or mixed-reality machines or software applications.

A method for motor training comprising: receiving from one or more sensors an orientation of a head mounted display of the subject; adapting a base video signal representing an avatar of the subject in a virtual reality to be displayed on the head mounted display wherein the avatar comprises a virtual limb corresponding to the limb that is injured; and sending the base video signal to the head mounted display for visualization. The method further comprises in response to a trigger signal from the subject, sending an exercise video signal representing the avatar in the virtual reality performing an exercise to start the visual rendering of the exercise in the head mounted display, even though the corresponding real limb is substantially immobile and provides no input at all. Such exercise is aimed at rehabilitation of the limb from the injury with the virtual limb corresponding to the immobile limb and it is displayed taking into account the orientation of the head mounted display. A computer program and computing systems for providing a treatment session for motor training are also disclosed.

A golf club head includes a top portion, a sole portion opposite the top portion, and a striking face configured to impact a golf ball. The striking face includes a face center and a variable thickness distribution such that the club head exhibits an Expected COR value of not less than 0.810, the Expected COR value being determined based on the following relationship $\mathrm{Expected}\mathrm{COR}=\underset{i=1}{\overset{n}{.Math.}}\underset{j=1}{\overset{m}{.Math.}}{p}_{\mathrm{ij}}*c_{\mathrm{ij}}$
The variable c.sub.ij corresponds to an average COR value associated with bin and the variable p.sub.ij corresponds to a bin-specific impact probability value. And the club head exhibits a characteristic time no greater than 257 microseconds.
