In one example, a muscle exercise device includes a first arm, a second arm rotatably connected to the first arm, and the second arm and first arm configured to cooperatively define a recess. The muscle exercise device also includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm, and a wireless transmitter disposed in either the first arm or the second arm, wherein the wireless transmitter is responsive to communications from an app residing on a user device.

A system for detecting a ball or strike in baseball.

A method for portable drill instruction for a sport can include: capturing a live video of a player of the sport in a venue for the sport playing a ball launched from a ball machine during a training drill for the player conducted in the venue; determining in response to the live video whether or not the player satisfies a training goal of the training drill when playing the ball; and providing a real-time feedback to the player during the training drill that indicates to the player whether or not the training goal is satisfied.

A wearable training apparatus has a vision-control assembly and a head-mounting assembly coupled to the vision-control assembly. The vision-control assembly has a see-through area corresponding to a central portion of the human field of vision (FOV), and a vision-blocking area for blocking the human peripheral FOV except the central portion thereof. The wearable training apparatus may be in the form of a pair of eyeglasses with lenses provided with reduced FOV or alternatively, may be in the form of a goggle with reduced FOV. A training system may comprise one or more wearable training apparatus, one or more imaging devices for recording images and/or video streams of the performance of users wearing the training apparatuses, and one or more computing devices for playing back and analyzing the recorded images and/or video streams.

A smart mirror can show live or recorded streaming video of an instructor performing a workout in a package that is attractive and unobtrusive enough to hang in a living room. The smart mirror includes a mirror surface with a fully reflecting section and a partially reflecting section. A display behind the partially reflecting section shows the video when the smart mirror is on and is almost invisible when the smart mirror is off. The smart mirror also has a speaker, a microphone, and a camera to enable a user to view the video content and interact with the instructor. The smart mirror may connect to the user's smart phone, a peripheral device (e.g., a Bluetooth speaker) to augment user experience, a biometric sensor to provide biometric data to assess user performance, and/or a network router to connect the smart mirror to a content provider, an instructor, and/or other users.

The present invention includes systems and methods for automated detection and visualization of offside positions. In soccer, offside is determined by the position of a player relative to the position of players on the opposing team and/or the soccer ball. The present invention provides systems and methods for tracking the location of players on a soccer field and for determining whether a player is in an offside position. The present invention further includes an imaging system for tracking the location of a boundary object that determines where offside positions begin. The system is then operable to enhance image and video data using the data collected during detection of offside positions.

According to one exemplary embodiment, an apparatus, system, method and/or computer program product may provide an athletic training performance analysis apparatus including at least one athletic training performance analysis device including at least one electronic sensor coupled to the at least one athletic training performance analysis device; at least one user interface coupled to the at least one athletic training performance analysis device configured to interact with a user to receive a user selection of at least one training performance analysis routine, the at least one user interface may include: at least one electronic computer processor coupled to the at least one electronic sensor; at least one input device coupled to the at least one electronic computer processor to receive the user selection; at least one output device coupled to the at least one electronic computer processor to provide output to the user; at least one electronic memory coupled to the at least one electronic computer processor; and at least one of: wherein the at least one electronic computer processor is configured to save or retrieve the at least one training performance analysis routine from the at least one memory; where the at least one electronic computer processor is configured to electronically monitor and electronically analyze the at least one training performance analysis routine based on the at least one electronic sensor; wherein the at least one electronic computer processor is configured to randomize at least one challenge by the at least one athletic training performance analysis device; or wherein the electronic computer processor is configured to at least one of: combine a plurality of previously saved of the at least one training performance analysis routine, or shuffle a plurality of previously saved of the at least one training performance analysis routine.

A gait evaluation apparatus that evaluates a training gait of a paralyzed patient suffering from paralysis in a leg includes an acquisition unit configured to acquire a plurality of motion amounts of a paralyzed body portion according to a gait motion and an evaluation unit configured to evaluate that the gait motion is an abnormal gait in a case where at least one of the motion amounts acquired by the acquisition unit meets any one of a plurality of abnormal gait criteria set in advance. The abnormal gait criteria include at least two or more first criteria, which are criteria relevant to motion amounts of different parts of the paralyzed body portion, or at least two or more second criteria, which are criteria relevant to motion amounts of the same part of the paralyzed body portion in different directions.

An electronic golf aid system for assisting users with reading greens on golf courses includes a camera that captures images of the user's field of view, and an electronic display device with a display screen that displays captured images. A processor, which communicates with the camera and display device, is programmed to: receive signals from the camera indicative of images of a golf ball and a cup on the green; determine respective locations for the golf ball and cup; determine a perspective view of the topology of the green between the golf ball and cup from the user's point of view; determine, based on the green's topology, a proposed trajectory line from the golf ball's location to the cup's location; and direct the electronic display device to display the proposed trajectory line superimposed on the surface of the green as the green is shown in real-time on the display screen.

A walking training system includes: a tension unit that pulls a leg of a trainee upward and forward; a sensor provided for determining a start timing of a swinging end phase of the leg; and a control unit that reduces a tensile force of the tension unit from the start timing of the swinging end phase.
