  • Management of wireless transmission rate of control signals for power assistive devices
    Patent number: 11672677
    Abstract: A system and method for transmission of a signal for a powered assistive device has a sensor node with a wireless transmitter adapted for digitally transmitting a transmitted signal, the sensor node adapted for receiving and monitoring a sensor signal from a sensor attached to a user, and a master node with a controller and a wireless receiver for receiving the transmitted signal from the wireless transmitter. The master node processes the transmitted signal and communicates a control signal to the powered assistive device. The wireless transmitter transmits the transmitted signal at a first rate when the wireless transmitter adapted to transmit the transmitted signal at a first rate when the sensor signal is indicative of the rest state and to transmit the transmitted signal at a second rate when the sensor signal is indicative of the active state, the second rate being greater than the first rate.

  • Prosthetic fingertip end effectors
    Patent number: 10869773
    Abstract: A prosthetic finger includes a main body and a terminal gripper at an end of the main body for enabling fine-motor grasping skills. The terminal gripper has at least two tongs movable relative to one another. The prosthetic finger includes a gripping mode and a flexion mode. In the gripping mode, the tongs of the terminal gripper are able to move relative to one another while the main body is not able to flex, and in the flexion mode, the main body is able to flex while the at two tongs is not able to move relative to one another.
