The present invention provides a roadkill and bird strike prevention system comprising: an ultrasound generating circuit module generating a control signal that generates frequency waves within predetermined ultrasound range; a connection wire electrically connecting between the ultrasound generating circuit module and a ultrasound output pad and transmitting the control signal generated from the ultrasound generating circuit module into the ultrasound output pad; and the ultrasound output pad attached to a body of a vehicle, such as a motor vehicle, an aircraft, and a watercraft, and outputting ultrasound waves using the control signal transmitted from the ultrasound generating circuit module through the connection wire.

A removable and reversible sliding mount for a marine transducer has a C-shaped mounting channel affixed to the transom of a boat. A closed bottom end of the C-shaped mounting channel is proximal to the bottom of the boat and an open top end of the mounting channel is at or above the water line of the boat. A mounting board having a handle at one end and a transducer at the other end may be slid into the mounting channel so that the transducer is positioned just below the bottom of the boat. The mounting board may in be inverted so that the transducer is positioned above the waterline of the boat. A locking mechanism may be used to secure the mounting board in the mounting channel. The mounting board may also include cable guides to secure a transducer cable along its length.

A fish finder transducer mount apparatus for independently controlling a directional transducer and trolling motor includes a clamp body. A motor clamp is coupled to the clamp body. The motor clamp is selectively engageable with the clamp body and configured to secure the apparatus to a propeller shaft of a trolling motor. A directional transducer shaft is rotatably coupled to the clamp body and a directional transducer shaft bottom end of the directional transducer shaft to receive a directional transducer of a fish finder. A gearing system is coupled to the directional transducer shaft to rotate the directional transducer shaft. A handle is coupled to the gearing system. The handle comprises an extension portion secured by a user to manipulate the orientation of the directional transducer shaft.

A method for forming a sensing system responsive to a wavefield of acoustic or seismic signals. One embodiment includes providing a foil layer having first and second opposing surfaces and piezoelectric properties. The foil layer, configured as a sheet, is positioned about a frame surface which provides the foil layer a stable shape while permitting the sheet configuration of the foil layer to be responsive to a wavefield of seismic or acoustic energy. Coupling between the foil layer and the frame is so limited as to render direct coupling of the foil layer with signals of the wavefield the predominant means for stimulating the sensor element with seismic energy.

A sensor with a chamber comprises a base, a cavity body, a sensing element, and a porous gel material. The cavity body is disposed on the base and has a cavity wall and an inner space formed inside the cavity wall, the sensing element is disposed on the cavity wall, and the porous gel material is disposed between the base and the cavity body, the porous gel material has a porosity of not less than 80%, so that gas is capable of communicating between the inner space of the cavity body and an outside, thereby forming a passage for gas to enter and exit to balance a pressure in the sensor with the chamber, increase a support of the sensor with the chamber, and reduce the risk of conventional bonding between the sensing element and the base using die-bonding adhesive.

Systems, methods, and apparatuses for conducting heat from an ultrasound transducer and reducing drop impact forces are disclosed. A thermal management system including a thermally conductive compliant component in an ultrasound probe is disclosed. The thermal management system may include thermally conductive compliant component coupled to a transducer assembly. A printed circuit assembly (PCA) may be coupled to the compliant component. The thermally compliant component may conduct heat from the transducer assembly to the PCA. The PCA may be further coupled to a cable that may conduct heat from the PCA and away from the ultrasound probe.

According to at least one aspect, a monolithic sensor mount can include a first cylindrical portion and a second cylindrical portion. The first cylindrical portion can have a first diameter and the second cylindrical portion can have a second diameter larger than the first diameter. The second cylindrical portion defining a recess region to host an ultrasonic transducer. The second cylindrical portion can have an outer surface that defines a male thread to mechanically engage a female thread of a cavity within a fluid flow tube configured to host the sensor mount.
