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.

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.

Methods, systems and apparatuses are disclosed for non-destructively a substrate using ultrasound waves, and enhancing resolution of imaging created from ultrasound signals that are back reflected from a substrate surface second, or back surface by maintaining the incident angles of the ultrasonic beams at the substrate second surface such that the ultrasonic beams strike the substrate second surface at an angle that is substantially perpendicular to the complex geometric profile of the substrate second surface by supplying known spatial coordinates to the system to maintain the incident angles of the ultrasonic beams at a predetermined angle relative to the substrate second surface.

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.

An underwater detection apparatus is provided which includes a transmission transducer, a reception transducer, and a motor. The transmission transducer transmits a transmission wave within a given fan-shaped transmission space, the fan-shaped transmission space having a first transmission width in a given first plane and a second transmission width in a second plane perpendicular to the first plane. The reception transducer receives, as a reception wave, a reflection wave of the transmission wave within a given fan-shaped reception space, the fan-shaped reception space having a first reception width in the first plane and a second reception width in the second plane, the second reception width being wider than the second transmission width, and in the second plane, the fan-shaped transmission space being within the fan-shaped reception space. The motor rotates the fan-shaped transmission space and the fan-shaped reception space.

A method includes: an arrangement step of arranging a phased array probe including a plurality of oscillators each of which is capable of emitting ultrasonic waves on an end surface of the rotor disc, in a parallel state in which the plurality of oscillators are arranged along a circumferential direction of the rotor disc; a first transmission step of emitting ultrasonic waves from the plurality of oscillators in the parallel state, while a timing of emitting the ultrasonic waves from each of the oscillators is controlled in a first emission pattern, and receiving reflection waves of the ultrasonic waves; and a second transmission step of emitting ultrasonic waves from the plurality of oscillators in the parallel state, while the timing of emitting the ultrasonic waves from each of the oscillators is controlled in a second emission pattern different from the first emission pattern, and receiving reflection waves of the ultrasonic waves.

An ultrasound probe may include a mechanical transducer and a probe housing. The mechanical transducer may be rotatable about an axis. The mechanical transducer may be operable to acquire ultrasound image data at one or more rotational positions of a plurality of rotational positions. The probe housing may include a probe cap covering the mechanical transducer. The mechanical transducer may be directed toward the probe cap at each of the plurality of rotational positions. The probe cap may include a defined structure having a first thickness and a remainder portion having a second thickness different than the first thickness. In various embodiments, at least a portion of the defined structure is at a center section of the probe cap corresponding with a center rotational position of the mechanical transducer.

A dual frequency ultrasound transducer includes a high frequency ultrasound array and a low frequency transducer positioned behind or proximal to the high frequency ultrasound array. In one embodiment, a dampening material is positioned between a rear surface of the high frequency array and the a front surface of the low frequency array. The dampening preferably is high absorbing of signals at the frequency of the high frequency array but passes signals at the frequency of the low frequency transducer with little attenuation. In additional, or alternatively, the low frequency can angled with respect to the plane of the high frequency transducer to reduce inter-stack multipath reflections. Beamforming delays compensate for the differences in physical distances between the elements of the low frequency transducer and the plane of the high frequency transducer.

A sensor device includes: a probe body having a first end and a second end, the probe body defining a probe cavity within the probe body; a sensor located at the first end of the probe body, the sensor having a sensor surface in sensory communication with the probe cavity defined within the probe body; a permanent magnet located adjacent the second end of the probe body and at least partially circumscribing the probe cavity defined within the probe body; an isolating boundary portion located between the permanent magnet and a surface of the object of interest and having a passage formed therethrough, the passage in communication with the probe cavity defined within the probe body.
