Abstract: 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.

Abstract: A fan assembly is disclosed. The fan assembly can include a first support frame. The fan assembly can comprise a shaft assembly having a first end coupled with the first support frame and a second end disposed away from the first end. A second support frame can be coupled with the first support frame and disposed at or over the second end of the shaft assembly. An impeller can have fan blades coupled with a hub, the hub being disposed over the shaft assembly for rotation between the first and second support frames about a longitudinal axis. Transverse loading on the shaft assembly can be controlled by the first and second support frames.
