| PURPOSE: A method for measuring the water level is provided to extend the available range of measurement by eliminating the need for receiving sonic pulses and to restrain the increase of an error even if the interval of sound pickups is lengthened. CONSTITUTION: A sonic wave oscillator oscillates a sonic pulse. The sonic pulse is propagated along waveguides toward the surface of water. Sound pickups sequentially outputs signals. The distance from the first sound pickup to the final pickup is calculated. The distance(theta L) from the final pickup to the surface of the water in the waveguides is calculated by measuring the time gap between the reception of an advancing wave by the final sound pickup and the reception of a reflected wave by the final sound pickup. The distance from the final pickup to the surface of the water in the waveguides is added to the distance from the first sound pickup to the final pickup to obtain the distance(Lx) from a starting point to the surface of the water. The distance from a starting point to the surface of the water is the water level. | ||||||

| A method of detecting objects includes transmitting toward an object a first acoustic signal including a first set of pulses including a first number of pulses, and checking if a first echo signal resulting from reflection of the first acoustic signal is received with an intensity reaching an echo detection threshold. If the intensity of the first echo signal reaches the echo detection threshold, the distance to the object is calculated as a function of the time delay of the first echo signal. If the intensity of the first echo signal fails to reach the echo detection threshold, one or more further acoustic signals are transmitted including a set of pulses wherein the number of pulses is increased with respect to the number of pulses in said first acoustic signal. | ||||||

| A proximity sensing function is implemented using a collection of core independent peripherals (CIPs) in a microcontroller without software overhead to the central processor during operation thereof. A pulse width modulation (PWM) peripheral generates a high frequency drive signal that is on for a short duration to an ultrasonic transmitting transducer. An ultrasonic receiving transducer receives reflected ultrasonic pulses during an integration time window. The received pulses are detected and integrated into a voltage value. The integrated voltage value is compared to a prior voltage value average, and if different, generates a proximity sense signal of an object. Direction, distance and speed of the object may also be determined from the voltage values. | ||||||

| Systems and methods are disclosed herein in which multi-level square wave excitation signals are used instead of or in addition to fully-analog excitation signals to drive an array of transceiver elements to create a sound field. Use of multi-level square wave excitation signals produces acceptable transceiver output with reduced complexity, cost, and/or power consumption as compared with use of fully-analog excitation signals. In addition, use of such signals facilitates system implementation using application-specific integrated circuits (ASICs) and is not as restricted in voltage level and speed. At the same time, the benefits and applications of fully-analog excitation signals (e.g., acoustic holography, beam superposition, signal-to-noise ratio (SNR) improvements, suppression of parasitic modes, increased material penetration, potential for coded pulsing algorithms and suppression of side lobes in ultrasonic field) can still be achieved with multi-level square wave excitation signals. | ||||||
