Abstract: A water heater system includes a tank having internal capacity no greater than 1 gallon, a water inlet, and a water outlet. A flow of water into the tank through the water inlet and out of the tank through the water outlet is a downstream water flow. An absence of downstream water flow is a standby condition of the water heater. The water heater includes a heating element for heating water in the tank, a first temperature sensor positioned to sense a temperature of the water flowing into the tank, and a second temperature sensor positioned to sense a temperature of the water flowing out of the tank. The water heater further includes a damper upstream of the second temperature sensor to reduce fluctuations in the temperature readings of the second temperature sensor to reduce false detection of downstream water flow.

Abstract: Systems and methods for eye tracking calibration in a wearable system are described. The wearable system can present three-dimensional (3D) virtual content and allow a user to interact with the 3D virtual content using eye gaze. During an eye tracking calibration, the wearable system can validate that a user is indeed looking at a calibration target while the eye tracking data is acquired. The validation may be performed based on data associated with the user's head pose and vestibulo-ocular reflex.

Abstract: A breakaway support configured to selectively release an actuator from a fitting and a method of providing the breakaway support. The breakaway support includes a race positioned between the actuator and the fitting. The second end of the actuator is connected to the fitting via a ball joint is positioned within the race. The ball joint permits the actuator to pivot about the ball joint in a vertical plane between a first position and a second position. The breakaway support includes a first knuckle that causes the actuator to release from the fitting when the actuator moves in a first direction beyond the first position. A portion of the fitting or a second knuckle may cause the actuator to release from the fitting when the actuator moves in a second direction beyond the second position. A portion of the actuator may break to release the actuator from the fitting.

Abstract: The present application describes a computer-implemented method for frequency hopping including configuring a radio front end to operate on a first frequency; receiving a transmit signal in a first path in the radio front end; amplifying a transmit signal in the first path; phase shifting the transmit signal in a second path in the radio front end, the second path being different from the first path; coupling the amplified transmit signal to a third path in the radio front end; coupling the phase-shifted transmit signal in the second path to the amplified transmit signal in the third path to form a carrier-cancelled signal in a fourth path in the radio front end in the radio front end; phase shifting the carrier-cancelled signal in the fourth path; coupling the phase-shifted carrier-cancelled signal in the fourth path to the amplified transmit signal in the first path; and reconfiguring the radio front end to operate on a second frequency.

Abstract: An acoustic disdrometer is provided for measuring precipitation. The acoustic disdrometer has an acoustic transducer positioned within an acoustic chamber defined by an acoustic shell. Precipitation impacting the acoustic shell generates sound waves that are collected by the acoustic transducer for processing.

Abstract: A lightshow control system for generating a lightshow across a plurality of pixels or mobile devices comprises a controller configured to receive a lightshow operator's input and to generate a plurality of lightshow parameters. The system comprises a beacon transmitter in communication with the lightshow controller and configured to receive the lightshow parameters from the lightshow controller, encode the lightshow parameters on a beacon signal, and broadcast the beacon signal to the pixels, wherein each pixel is configured to receive and decode the beacon signal to perform one or more display actions. The decoded beacon signal includes reference timing information to facilitate synchronization of the pixels. The display actions may be based in part on the individual pixel location which is determined by the pixel based on TDOA multilateration and/or trilateration from distinct audio signals emitted by a plurality of speaker nodes.
