There is provided a limb exercise device comprising: a force sensor configured to determine a weight applied to the device; a sliding component configured to facilitate the sliding movement of the device along a separate surface, wherein the separate surface is a surface that is separate to the device, wherein the sliding component comprises a part of an external housing of the device; a device movement sensor configured to determine a movement of the device on the separate surface; a limb position sensor configured to determine a position, in at least one dimension, of a limb of a user positioned above or adjacent to the device; and an output device configured to output an indication in dependence on a signal from at least one of: the force sensor, the device movement sensor and the limb position sensor.

An arrangement for aligning a pair of game boards as used in a tossing game such as cornhole, the arrangement including alignment fiducials located along a center line of each game board and an alignment system that uses a marking line that uses the fiducials to achieve alignment (and perhaps also proper spacing) between the pair of game boards. The marking line of the alignment system may be either a laser-based source or a non-elastic weighted string source.

A treadmill according to the present invention includes: a frame; an endless belt; an endless-belt drive unit; a plurality of cameras provided on the frame such that the orientations and/or locations thereof can be adjusted; a motion-data acquisition unit that markerlessly acquires motion data of a subject by using image information obtained with camera images; a motion analysis unit that analyzes the motion of the subject by using the motion data; and a control unit that controls the endless-belt drive unit based on the motion data.

An electronic device and method for detection of intentional contact between an object and a body part of a player are provided. An electronic device receives a plurality of frames of a video from an imaging device. The electronic device tracks a movement of the object and a movement of the body part across the plurality of frames. The electronic device determines, based on the tracked movement, a frame of interest from the plurality of first frames in which degree of overlap between position coordinates of the object and position coordinates of the body part of the player exceeds an overlap threshold. The electronic device detects a contact between the object and the body part of the player based on the frame of interest. The electronic device applies a machine learning model on the frame of interest and the tracked movement to determine whether the contact is intentional.

An exercise machine comprises a motor. The exercise machine comprises a lockable translatable mount. The exercise machine comprises a cable coupled to the motor via the lockable translatable mount. The exercise machine comprises a sensor coupled to the lockable translatable mount. The sensor is used at least in part to determine mount lock state.

A system and method for targeted neurological treatment using brainwave entrainment therapy with passive treatment that allows for targeted treatment of particular areas of the brain, particular neurological functions, particular neurological states, and combinations of areas, functions, and states. The system and method receive gait parameters for an individual and compare those against a database of historical gait data to determine if an onset neurodegenerative condition is present, and applies a brainwave entrainment therapy responsive to the determination of the condition. The system and method receive a neurological assessment identifying areas of the brain or neurological functions to be treated, select one or more treatment modalities and frequencies, select a treatment regimen, and apply brainwave entrainment using a treatment regimen while the subject engages in dual-task activities selected to stimulate the areas of the brain, neurological functions, or neurological states to be treated, enhanced, or altered.

Disclosed herein are robust disposable alternating tangential flow (ATF) housing and diaphragm pump units and associated methods of manufacturing, testing, wetting, and using the same.

A jump training apparatus and method designed to allow athletes to perform sets of standing vertical jumps. The apparatus is comprised of a mount, a T-tube, a notched post, and a plurality of vertically hanging rotational vanes of varying lengths. Each rotational vane has a longitudinal member with a planar surface. Each rotational vane has a cylindrical opening with a stop member. The plurality of rotational vanes are placed over the notched post by aligning the stop member with a channel cut in the notched post. When the stop member contacts the edges of the channel, it causes the rotational member to stop rotating. A central bump in the channel further inhibits motion.

A force detection system includes first and second sets of pressure sensors, memory, and a processing module. The first set of pressure sensors are in an insole of a shoe and the second set of pressure sensors are in an outsole of a shoe. The processing module receives first data regarding the first set of pressure sensors and generates a first digital representation of the first data. The processing module also receives second data regarding the second set of pressure sensors and generates a second digital representation of the second data. The processing module also writes the first and second digital representations to the memory.

Embodiments are directed to an electronic home plate system that 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 detecting motion includes capturing a first frame, capturing a second frame, subtracting the first frame from the second frame to create an image, and checking for pixel changes between the first frame and the second frame. The detected motion of the ball includes the ball passing over the home plate enclosure or the ball passing near and not over the home plate enclosure.
