Publication number: 20240090349Abstract: There is provided an electrical switch comprising a length of superconducting material. In some forms the electrical switch is configured to be controlled between a low-resistance state and a higher-resistance state by the selective application of one or more switching mechanisms. In the higher-resistance state, current flowing through the length of superconducting material may approach the critical current of the length of superconducting material, may be substantially equal to the critical current or may be greater than the critical current. In some forms, the length of superconducting material is a length of high temperature superconducting material.Type: ApplicationFiled: January 26, 2022Publication date: March 14, 2024Inventors: Rodney Alan Badcock, Christopher William Bumby, Jianzhao Geng, James Hamilton Palmer Rice

Publication number: 20220404622Abstract: Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. EM information from the sensor can be analyzed to determine location and/or orientation of the sensor and thereby the wearer's pose. The EM emitter and sensor may utilize time division multiplexing (TDM) or dynamic frequency tuning to operate at multiple frequencies. Voltage gain control may be implemented in the transmitter, rather than the sensor, allowing smaller and lighter weight sensor designs. The EM sensor can implement noise cancellation to reduce the level of EM interference generated by nearby audio speakers.Type: ApplicationFiled: August 24, 2022Publication date: December 22, 2022Inventors: Brian Bucknor, Christopher Lopez, Michael Janusz Woods, Aly H. M. Aly, James William Palmer, Evan Francis Rynk
