摘要： Various methods and systems are provided for a multi-frequency transducer array. In one example, ground recovery in the transducer array is enabled by configuring an acoustic stack of the transducer array with an interdigitated structure, a top layer coupled to a front side of the interdigitated structure, and a bottom layer coupled to a back side of the interdigitated structure, where the top layer and the bottom is electrically continuous with the interdigitated structure.

摘要： An ultrasonic detection circuit includes a transmitter circuit that provides excitation signals to an ultrasonic transducer during an excitation interval. A control circuit includes a port to receive a command. The control circuit controls the frequency and the duty cycle of the excitation signals of the transmitter circuit during the excitation interval. The control circuit generates a first excitation signal sequence of the excitation interval followed by a first monitoring period to receive a first echo signal in response to the command. The control circuit generates a second excitation signal sequence of the excitation interval followed by a second monitoring period to receive a second echo signal in response to the command. The control circuit outputs results via the port based on at least one of the first or second echo signals received.

摘要： A broadband ultrasonic transducer device (UTD) is disclosed that utilizes a plurality of narrow-band piezo electric elements grouped into single-frequency sub-arrays to provide a relatively simple, highly-reliable deterrent unit (DU) capable of emitting ultrasonic energy over a wide coverage area and at a sound pressure level that meets or exceeds other DU approaches. In an embodiment, the broadband UTD includes a housing portion configured to couple to a plurality of piezo sub-array plates. Each piezo sub-array plate includes a plurality of pockets or cavities to receive respective narrow-band (e.g., 1-3 kHz) piezo electro transducer elements with characteristics, e.g., geometries and material composition, that cause each to emit ultrasonic energy at a particular resonant frequency. A controller of the UTD implements a control scheme to emit ultrasonic energy in a plurality of output modes including a white noise node and a single-frequency mode for deterrence applications.

A plurality of elements are provided in the probe tip. Each element emits ultrasound waves using a long pulsed signal with each element having a different resonant frequency. Each element also receives ultrasound energy in a continuous mode. A selector is manually controlled by a practitioner to select the active element. The output may take a variety of forms. For example, the output may be printed, displayed, recorded to a memory, and/or played through a speaker or headset.
