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).

Strength training and exercise platform

Aspects of the present disclosure involve a power module, which may include an inverter circuit employing semiconductor switch dies. In the presence of a failure of a die, which may include an arc from a short, a sensor produces a signal responsive to the failure. The signal initiates an indirect fuse, such as a pyrotechnic element, that opens conductors associated with the die. For example, the die or a related die may be wire bonded to terminals of the module. The indirect element may therefore open the bonds to the terminals to isolate the failed die and/or related dies.

Self clearing power module

Aspects of the present disclosure involve an inverter employing switches of different types in parallel. In one example, an apparatus includes a voltage-source converter that may have a plurality of switch positions collectively coupled to convert an input to an output. At least one switch position may include a first switch of a first switch type and a second switch of a second switch type different from the first switch type. Also, the first and second switches may be coupled in parallel. The converter may also include a switch control circuit to generate, for each of the at least one of the switch positions, a first control signal to operate the first switch of the switch position, and a second control signal to operate the second switch of the switch position.

Systems and methods for dynamic resistance training are provided that include the use of a dynamic force module. The dynamic force module includes an actuator and controller adapted to control the actuator according to a force profile that specifies the relationship between an operational parameter of the actuator and a measured parameter associated with a user performing an exercise. The dynamic force module is also capable of communicating with a broader network system to facilitate storing and distribution of force profiles and user profile information. The network system further includes features for, among other things, generating and managing force profiles, uploading multimedia content, and tracking user progress.
