Abstract: An exercise machine component comprises a cable connection base adapted to attach to an end of a cable, a chamber adapted to receive a key through an opening of the chamber, a biasing mechanism within the chamber, and a receiving groove within the chamber wherein the biasing mechanism biases the key against the receiving groove so that the key is securely fixed within the chamber.

Abstract: An exercise machine comprises an arm support, including: a carriage configured to slide within a track attached to the exercise machine; and a support assembly that floats the carriage relative to the track, wherein the support assembly is disengaged by the application of force via the arm. An exercise machine comprises a rotatable column, wherein the column supports an arm, and a gear detent mechanism to support a discrete number of positions for the rotatable column. An exercise machine comprises a tiltable arm, and a mechanism to support a discrete number of positions for the tiltable arm.

Abstract: An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

Abstract: A resistance force is controlled such that a user's effort against the resistance force results in a first isokinetic seed movement, wherein the user is an exercise machine user using an exercise machine. The resistance force required to effect the first isokinetic seed movement is associated with a predetermined force-velocity profile. A strength determination of the user is made based at least in part on the required resistance force and the associated predetermined force-velocity profile.

Abstract: A request is received for a higher torque from a torque controller than is possible from a power supply. The torque controller is coupled to a motor and the power supply, and the motor is coupled to an actuator. The actuator ultimately establishes resistance for a user in an exercise. An energy storage device is discharged to the motor in order to generate the higher torque, wherein the energy storage device is indirectly coupled to the torque controller.

Abstract: An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.

Abstract: An exercise machine comprises a motor, a gearbox coupled to the motor, a spool coupled to the gearbox, and a cable wound about the spool. The gearbox comprises bevel gears.

Abstract: 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.

Abstract: An exercise machine comprises a tension generating device, a translatable arm mount coupled to the tension generating device, an arm coupled to the translatable arm mount, and a cable coupled to the tension generating device via the arm.
