A portable smart hand grip according to an embodiment of the present disclosure includes a first housing, a guide part combined with the first housing and including a first receiving portion and a second receiving portion, a second housing facing the first housing and having a first pressing portion and a second pressing portion which are received in the first receiving portion and the second receiving portion, respectively, a first elastic member disposed between the first pressing portion and the first housing, a second elastic member disposed between the second pressing portion and the first housing, a sensor received in the first housing for detecting a user's operation of the portable smart hand grip, a control circuit unit received in the first housing to control an operation of the sensor, and a battery unit received in the first housing to provide power to the control circuit unit.

Disclosed is a rehabilitation training apparatus. The rehabilitation training apparatus includes a pair of first tracks formed parallel to each other along first axis, a second track disposed on the pair of first tracks, and moving along the first axis, and formed along second axis, a hand holder disposed on the second track, and moving along the second track, and on which at least one of hand and arm of a user is held, a stopper for a track disposed on the pair of first tracks for limiting a movement range of the second track, and a stopper for a holder disposed on the second track for limiting a movement range of the second pair of first tracks, wherein the first axis and the second axis are disposed with an inclination.

A sports training system includes an array of break beam sensors. Each sensor is configured to detect a passage of an object, such as a hockey puck, between adjacent posts and provide information for the passage to a controller communicatively attached to the array of sensors. A mobile application is configured to receive information from the controller and provide, for presentation to a user, passage statistics for the passages completed by one or more players. Servers are located in at least one data center. The servers are configured to receive and store the passage statistics and to provide access to the passage statistics.

An exercise apparatus includes a linear arm portion having an elongate arm member with proximal and distal ends and an elongate support member having proximal and distal ends. The arm member can be slidably mounted to the support member by a sliding joint. A linear arm brake assembly can be coupled to the arm member for resisting linear motion of the arm member. A torso portion can be included to which the linear arm portion is rotatably mounted about a second axis by rotary shoulder joint. The linear arm portion can be configured, and the rotary shoulder joint can be positioned along the length of the support member at a location that substantially balances the linear arm portion about the rotary shoulder joint at least when the arm member is in the retracted position.

A walking training system includes a treadmill, a center-of-gravity position detection unit that detects a center-of-gravity position of a trainee from a load received from a sole of the trainee on a belt of the treadmill, a posture detection unit that detects a posture of the trainee, a center-of-gravity position estimation unit that estimates the center-of-gravity position of the trainee from the detected posture of the trainee, a determination unit that determines whether a difference between the detected center-of-gravity position and the estimated center-of-gravity position exceeds a predetermined value, and a notification unit that sends, when the determination unit determines that the difference exceeds the predetermined value, a notification notifying that whether the difference exceeds the predetermined value.

Sensor data is collected from a sensor monitoring a tension generating device of an exercise machine. The sensor data is analyzed to determine whether the sensor data is within a specification. In the event the sensor data is not within the specification, an error stop mode is entered for the tension generating device.

A system for a quantitative detection of a movement. The system includes a signal emitter and two signal receivers, positioned in series, along a first axis parallel to a second axis of movement of a reflective marker provided on a moving object. The reflective marker is configured to reflect a signal emitted by the signal emitter towards the two signal receivers. The two receivers have a signal reception coverage such that allows existence of a reflective marker position, on the second axis, in which the reflective marker of a given size is recognized simultaneously by the two signal receivers.

A pegboard of the present disclosure includes: a main device including multiple unit modules; a board plate including multiple receiving portions; and multiple pegs to be inserted into the multiple receiving portions, and the multiple unit modules include multiple sensor modules configured to sense whether the multiple pegs are inserted into the multiple receiving portions and multiple light source modules configured to output light to the multiple receiving portions.

An electronic home plate system includes a home plate enclosure and at least one image sensor system disposed within the enclosure, each image sensor system including an image sensor, a lens and a first processor. The first processor is adapted to detect a motion of a ball by continuously capturing frames from the image sensor. The detected motion includes the ball passing over the home plate enclosure or the ball passing near and not over the home plate enclosure.

An interactive exercise apparatus for guiding a user to perform exercises includes a frame, a mirror, a display device, a driving mechanism, a determination unit, and a control unit. The mirror is movably mounted on the frame and configured to reflect an image of the user. The display device is disposed on a backside of the mirror and visible through the mirror. The driving mechanism is mounted between the frame and the mirror for electrically driving the mirror to move with respect to the frame. The determination unit is configured to determine location or posture of the user who performing the exercise. The control unit is operable to control the driving mechanism according to the location or posture of the user identified by the determination unit so as to control the mirror to move to a suitable position where the user can see their reflected image.
