The present invention is directed to a mounting device for a fish finding apparatus and, more particularly, to a motorized mounting device which includes an adjustable length pole used to mount a sonar transducer or other device an angler may be interested in mounting to the end of the pole that enters the water. The pole is used to spin the transducer or other apparatus in a clockwise and counterclockwise direction with a switch that is adapted to be operated by the angler's foot or a wireless remote. The mounting device is configured to be secured to a boat or mounted on a boat troll motor whereby the adjustable pole is secured and spins independent of the troll motor shaft.

An ultrasound energy delivery system is provided that includes a transducer and a housing.

A method of manufacturing a panel transducer scale package includes securing acoustic components at predetermined locations on a first carrier substrate with a first surface of the acoustic components positioned adjacent to the first carrier substrate. ASIC components are also secured at predetermined locations on the first carrier substrate with a first surface of the ASIC components positioned adjacent to the first carrier substrate. Photoresist resin is applied over the acoustic components and the ASIC components such that a second surface of the acoustic components is left exposed from the photoresist resin. The first carrier substrate is removed to expose the first surface of the acoustic components and the first surface of the ASIC components. A buildup layer is formed including electrical pathways between each of the acoustic components and the ASIC components, and the photoresist resin is removed.

The present invention relates to an ultrasound transducer assembly (10), in particular for intra vascular ultrasound systems. The assembly (10) comprises a transducer array (12) including a plurality of transducer elements (14) for transmitting and receiving ultrasound waves. Two support elements (16, 18) are provided for supporting the transducer array (12) in a curved or polygonal shape. The support elements (16, 18) are connected via a flexible connection layer (20) to the transducer array (12) for flexibly connecting the support elements (16, 18) to the transducer array (12).

An ultrasonic transducer includes a case, a piezoelectric element, a wiring member, a foaming member, and a vibration damping material. The case includes a bottom wall. The piezoelectric element is disposed on the bottom wall inside the case. The wiring member is electrically connected to the piezoelectric element. The foaming member is disposed on the piezoelectric element. The vibration damping material is disposed between the piezoelectric element and the foaming member. The foaming member has a bottom surface opposing the piezoelectric element in a thickness direction of the piezoelectric element. A plurality of depressions is formed on the bottom surface. The vibration damping material bonds the piezoelectric element and the bottom surface.

The invention relates to an ultrasonic sensor device (2) for a motor vehicle, having an ultrasonic sensor (3) which has a diaphragm (8) for emitting and/or receiving an ultrasonic signal, and having an attachment device which is configured, in a correct installation position of the ultrasonic sensor device (2) on an exterior panelling part (6) of the motor vehicle, to press the diaphragm (8) against an inner side (7) of the exterior panelling part (6) with a prestressing force, wherein the attachment device has a securing apparatus (5) and a cover apparatus (4), wherein the securing apparatus (5) can be arranged on the inner side (7) of the exterior panelling part (6) and has an opening (22) in which the diaphragm (8) is arranged, and wherein the cover apparatus (4) has a receptacle (24) in which a rear side (23), lying opposite the diaphragm (8), of the ultrasonic sensor (3) is secured, and wherein the cover apparatus (4) and the securing apparatus (5) are connected in a positively locking fashion.

A system for maintaining coherence of ultrasound waves emitted by multiple transducer arrays includes multiple retention arms, each for receiving one of the transducer arrays; a connecting frame for receiving and mechanically retaining the arms in fixed angular relation to each other; and a processor configured to determine relative locations of the transducer arrays with respect to one another and the connecting frame; determine a location of the connecting frame relative to an anatomic region of interest; determine a spatial arrangement of the transducer elements in each transducer array with respect to the anatomic region of interest; and adjust a transmission configuration of the transducer elements in the transducer arrays to achieve a desired focusing property with respect to the anatomic region of interest while maintaining coherence therebetween.

A stern operatively mounted universal transducer for boat includes a mounting device, having upper and lower brackets, for securement to the boat, preferably its transom, the upper and lower brackets secure a drive cylinder, which when operative, lowers a drive rod for shifting a sonic transducer upwardly above the water, or downwardly into the water to scope the surrounding underwater typography. A pair of guide rods shiftably extend through the upper and lower brackets, and at their upper ends, secure to a motor and gear housing, the guide rods at their lower ends secure to a base plate. A transducer shaft extends into the motor housing which provides for its pivoting, and at its lower end, extends downwardly through the base plate, and secures a transducer mounting plate, to which the transducer is affixed, in preparation for its usage. Electrical, pneumatic, or hydraulic pressure can be used to pivot the transducer shaft, and to raise and lower the base plate that connects with the drive shaft, the latter when operative, raises or lowers the entire transducer assembly into and out of the water, during application.
