Patent number: 11931085Abstract: A driver-specific back-out prevention mechanism is disclosed that includes a screw and a body. A first driver can be used for coupling and decoupling the screw with the body, and a second driver can only be used for adjusting the position of the screw in the receiving body. The body includes a cavity for receiving a head of the screw, with the cavity having an inward flange. The screw includes upper and lower sockets, with a channel extending though the head from the lower socket and a lock body disposed in the channel. Engagement with the first driver allows the locking body to move such that the fastener can be inserted and removed from the body. Engagement with the second driver displaces the locking body such that the locking body interferes with the flange such that screw fastener cannot be removed from the body by the second driver.Type: GrantFiled: December 30, 2021Date of Patent: March 19, 2024Assignee: MEDOS INTERNATIONAL SÀRLInventors: Keanan R. Smith, Joshua Rodriguez, Raymond F. Murphy

Patent number: 11621583Abstract: A wireless power transfer system includes a transmitter configured to transmit power to a receiver, for example, through coupled resonators. The transmitter receives feedback from the receiver, and uses the feedback to control the power transmission, to control a parameter at the receiver, for example, a rectified voltage output by the receiver. The feedback to the transmitter may be provided, for example, by an out-of-band radio system between the transmitter and receiver, by a reflection coefficient at the transmitter, and/or by an encoded modulation of power in the receiver, for example, in an impedance matching module. The transmitter may control the transmitted power, for example, by controlling a transmitter signal generator voltage (VSIG), a transmitter gate driver voltage (VGD), a transmitter amplifier voltage (VPA), and/or an impedance setting in a transmitter impedance matching module.Type: GrantFiled: August 30, 2021Date of Patent: April 4, 2023Assignee: University of WashingtonInventors: Joshua R.
