Abstract: The present disclosure provides a power switch for use in a power management system including a power source for supplying an electrical current, and a load for receiving the electric current upon establishing a circuit with the power source. The power switch includes a motion sensor, a timer, and a gate. The motion sensor is configured to sense a motion related to an operation of the load and generate an idle signal when the sensed motion is below a predetermined threshold. The timer is coupled with the motion sensor, and it is configured to activate a power-off signal upon detecting the idle signal for a predetermined time period. The gate is coupled with the timer, and it is configured to either complete the circuit when the power-off signal is inactive or break up the circuit when the power-off signal is active.

Abstract: A flow meter system includes a first ultrasonic transducer array to be flush-mounted to a pipe. The system also includes a second ultrasonic transducer array to be flush-mounted to the pipe. The system further includes a controller coupled to the first and second ultrasonic transducer arrays and configured to cause bidirectional beam steering between the first and second ultrasonic transducer arrays.
