Rowing machines are described that permit a rower to adjust the rowing resistance using a gear shift mechanism. The rowing machine includes a handle connected to a chain, which passes, sequentially, over a derailleur and then to the gears of the gear cassette. The gear cassette is coupled to a resistance unit, which may be similar to resistance units used in off wheel bicycle trainers. This configuration of derailleur and gear cassette permit the rower to smoothly select a gear.

This disclosure relates to using a hand held target (e.g. tae kwon do paddle) as a tool for providing physical performance instructions according to a digital workout performance template loaded in advance.

A method, including scanning a golf club to obtain scanning information; inputting the scanning information into a processing system; using at least one camera positioned behind and in-line to a golf swing direction and at least one lighting unit to obtain a series of images of a golf club during the golf swing; converting the series of images into parameterized motion representations; using at least one radar to obtain a radar signal; inputting the parameterized motion representations and the radar signal into the processing system; receiving golf club parameters and golf swing parameters as an output of the processing system; and generating a visual model of the golf club and the golf swing in a virtual space using the golf club parameters and the golf swing parameters.

The present embodiments provide systems and methods for aggregating measurements captured by different technologies during a golf swing. By capturing measurements using different technologies, more accurate measurements may be provided to a user by selecting from the measurements, offsetting measurements based on the technologies used, and aligning measurements between devices. Further, by aggregating measurements received from different devices, additional features and functionality may be provided to the user that is absent from any one device used alone. Additionally, by storing the aggregated measurements, users, club fitters and instructors may access and leverage larger databases of measurements to better understand the user's golf swing and to provide better recommendations and instruction to the user.

A system for creating and viewing indexed video snippets of a series of shots toward a goal comprising at least one sensor directly connected to a microprocessor, the microprocessor configured to trigger responsive to a ball-shooting detection of at least one of the series of shots toward the goal; electronic times that represent the accurate timing of a triggering event related to the ball-shooting detection; one or more video recordings captured by at least one recording source; wherein the electronic times are utilized to associate portions of the one or more video recordings with corresponding shots toward the goal; the associated portions are stored as separate video snippets; and the video snippets are indexed by the corresponding shots toward the goal.

An apparatus for remote controlled physical activity monitoring, the apparatus comprising: at least one orientation measurer, wearable on at least one body part of a user, configured to measure orientation of a body part wearing the orientation measurer during a physical activity of the user, at least one pressure meter, wearable on at least one body part of the user, configured to measure pressure applied by muscle of a body part wearing the pressure meter during the physical activity of the user, a computer processor, associated with the orientation measurer and pressure meter, configured to derive monitoring control data from the measured orientation and pressure, and a data transmitter, associated with the computer processor, configured to transmit the monitoring control data to a physical activity monitoring device, and thereby to remotely control a monitoring of the physical activity of the user by the physical activity monitoring device.

A shoe includes: a heel portion; a toe portion; a sole portion; and an electrical assembly. The electrical assembly includes at least: a magnetometer configured to determine a direction of movement of the shoe; and an accelerometer configured to determine acceleration of the shoe. Direction and acceleration data are used to generate a display of a map indicating traversal of a route by a wearer of the shoe at user interface of a user device.

A system for creating and viewing indexed video snippets of a series of shots toward a goal comprising at least one sensor directly connected to a microprocessor, the microprocessor configured to trigger responsive to a ball-shooting detection of at least one of the series of shots toward the goal; electronic times that represent the accurate timing of a triggering event related to the ball-shooting detection; one or more video recordings captured by at least one recording source; wherein the electronic times are utilized to associate portions of the one or more video recordings with corresponding shots toward the goal; the associated portions are stored as separate video snippets; and the video snippets are indexed by the corresponding shots toward the goal.

A computer-implemented method for displaying a predetermined sequence of exercise routines is provided. The method includes receiving a light sequence for the predetermined sequence of exercise routine from an application interface of a user device. The method further includes triggering one or more light emitting elements of a set of light emitting elements disposed on an exercising mat and detecting a movement on one or more touch buttons of a set of touch buttons on the exercising mat. The method includes determining a state of each of the corresponding one or more touch buttons upon detection of the movement. Furthermore, the method includes activating a debounce mechanism to delay in illuminating next one or more light emitting elements of the set of light emitting elements based on the state and displaying the light sequence on the exercising mat for guiding a user for performing the predetermined sequence of exercise routines.

A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.
