An indication is received from a user to rack or unrack a digital weight. A motor is signaled to apply or remove tension to a cable couple to the motor based at least in part on the indication. The actuator is connected to the cable and is physically arranged to deliver a force to the user. The motor selectively tensions a cable in accordance with an exercise program.

A smart ball (100) comprising: an inner sphere portion (12) consisting of a cork like material and an outer sphere (19) that ensconces said inner sphere, said inner sphere further comprising: a cylindrical cavity (14), located substantially at the core of said ball, said cavity formed by drilling into said cork from an operative top side; a sensor assembly (16) placed in the centre of said cylindrical cavity along a reference plane defined by a locus of points wherein said points being collinear points running from a first end of said seam (18) to a second end of said seam, thereby ensuring that orthogonal measurements of said sensor assembly being aligned with orthogonal axes of said ball; and a charging port on said seam, said charging port connected to a battery placed in said cylindrical cavity and said battery connected to said sensor assembly.

An exercise management and reporting system includes a weightlifting rack having a plurality of vertical members. Each of the vertical members include bar support brackets for receiving a barbell and weighted plate combination. Tracking sensors are positioned along the vertical members to track the movement of the barbell during an exercise. A control unit having a memory and wireless transmitter are provided along the rack. Weight sensors are positioned within each of the bar support brackets, and a wireless accelerometer is positioned along the barbell. The system also includes an exercise management application that receives the exercise data from the control unit and recommends and adjusts exercise workouts based on the received exercise data for each system user.

A method for determining a direction of a spin axis of a rotating apparatus which includes an XYZ-magnetic field sensor. The method includes determining a global direction of a magnetic field; rotating the rotating apparatus around the spin axis, measuring at least one magnetic field value as a function of time with the XYZ-magnetic field sensor when the rotating apparatus is rotating about the spin axis, computing a magnetic field component of the magnetic field in a direction of a local body co-ordinate of the spin axis of the rotating apparatus from the measured at least one magnetic field value and determining a direction of the spin axis using the computed magnetic field component of the magnetic field and the determined global direction of the magnetic field.

The invention relates to a system for collecting and processing data associated with players playing a ball game, where the ball comprises at least one RFID transmitter in the form of a passive RFID tag. For every player, an active RFID radio frequency sensor is worn on every limb authorized to come into contact with the ball, said RFID sensor being able to measure the instantaneous distance between the RFID sensor and the RFID transmitter from the strength of the radio frequency signal received from the RFID transmitter. An accelerometer measures the instantaneous acceleration of said limb. A microprocessor and a memory are used for time-stamping and storing the measurements output by the RFID sensor and the accelerometer for the purpose of post-processing. A central processing unit runs a program configured to read and process the data recorded in the memory units worn by the players and to deduce therefrom data representative of certain physical or technical information related to the play of the players.
