A system and method wherein ball spin rate and axis orientation are determined according to an electronic circuit that includes a magnetometer spin sensor module and, in the alternative, an electronic circuit that includes a spin sensor module with a plurality of accelerometers.

An exercise device includes a base defining an inner volume and a top supported by the base, the top defining an aperture. The exercise device further includes a force sensor configured to measure force on the top and a motor disposed within the base and below the top, the motor including a cable extendable through the aperture. The exercise deice further includes a controller communicatively coupled to each of the force sensor and the motor. The controller is adapted to actuate the motor in response to forces applied to the top as measured by the force sensor. The controller may also actuate the motor in response to one or more additional parameters related to the speed or force with which the cable is manipulated (e.g., pulled by a user).

Load data is received from a first exercise machine. An updated resistance for a second exercise machine is determined based on the load data received from the first exercise machine. A request to update a resistance associated with the second exercise machine is provided to the second exercise machine. The second exercise machine updates the resistance associated with the second exercise machine based on the request.

An electromechanical device for rehabilitation includes a motor and a control system including one or more processing devices operatively coupled to the motor. The one or more processing devices are configured to, responsive to a first trigger condition occurring, control the motor to operate in a passive mode, responsive to a second trigger condition occurring, control the motor to operate in an active-assisted mode, and responsive to a third trigger condition occurring, control the motor, by providing resistance, to operate in a resistive mode.

Systems, methods and computer readable media comprising a virtual exercise board, which is represented by images on the screen of a pad device; wearable devices configured to attach to each shoe of a user and to collect and transmit touch data to the pad device; cameras for tracking movement and calibrating with the data collected by the wearable devices; and computer programs for collecting user data, processing user data, and generating outputs. In embodiments, features include augmented reality; ratings of performance; automated workouts/protocols; real-time progress bar; multi-location database capabilities; and reports.

A weight machine sensor includes a force sensor, a position sensor, and a processor. The force sensor is programmed to output a force signal representing a force applied to a pulley-disposed on a cable incorporated into exercise equipment having a stack of weights. The position sensor is programmed to detect motion of the stack of weights and output a position signal representing the motion detected. The processor is programmed to receive the force signal and the rotation signal and determine, from the force signal and the position signal, exercise data including an amount of exercise resistance and a number of repetitions performed.

A system for rehabilitation is disclosed. The system for rehabilitation includes one or more electronic devices comprising one or more memory devices storing instructions, one or more network interface cards, and one or more sensors, wherein the one or more electronic devices are coupled to a user. The system for rehabilitation further includes one or more processing devices operatively coupled to the one or more memory devices, the one or more network interface cards, and the one or more sensors. The one or more processing devices are configured to execute the instructions to receive information from the one or more sensors. The one or more processing devices are further configured to execute the instructions to transmit the information to a computing device controlling an electromechanical device, via the one or more network interface cards.

An exercise device allows a user to move the mass of weights in various directions while mitigating the downward force of gravity on the weights. A telescoping pole includes a platform that supports weight plates in place during exercise, and may be assembled at different lengths depending upon the height of the user. A handle may be coupled to the telescoping pole to hold the weights on the platform and provide varying grips. The telescoping pole may be inserted into and moveably engaged with a base portion that holds a lower portion of the exercise device at a static position within the base while the handle is moved in varying directions.

An exercise device is portable and lightweight, where a user pushes levers (for example, handles or pedals) in a linear fashion. The levers may not be connected to each other and may be used alternately or both at the same time. Each lever is connected to a bearing mechanism inside of a housing, where the bearing mechanism reduces friction and creates stability when pushing the levers. The levers are attached to one or more sets of resistance bands that enable different levels of resistance by rotating a top dial to vary the intensity of physical activity. The device has a base having foldable base supports and foldable pedals, thus providing portability of the device. The exercise device may have a pedometer situated within one of the levers that counts the steps and may communicate with an application executing on a mobile device in order to measure the user's exercise performance.
