    摘要: 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.

    摘要: A mounting assembly includes a mounting block. A first shaft is supported by the mounting block and movable about a first rotational axis of the first shaft and a first extension axis with respect to the mounting block. A clamp is attached to the first shaft, wherein the clamp interfaces with the mounting block to limit movement of the first shaft along the extension axis while allowing rotation of the first shaft about the first rotational axis. A second shaft is coupled to the first shaft and movable about a second rotational axis of the second shaft.

    摘要: A transducer (140) having a mechanical impedance over an operative frequency range and having a desired power coupling (145) to a load over the operative frequency range comprises a piezoelectric device (141) having a frequency distribution of modes in the operative frequency range; and an overmould (143). The overmould (143) is arranged to surround at least part of the piezoelectric device (141); and the parameters of the overmould (143) are selected to provide a required impedance matching between the mechanical impedance of the transducer (140) and the mechanical impedance of the load. An alternative transducer comprises a mounting means for holding a discrete portion of at least a part of the periphery of the piezoelectric device wherein the parameters of the mounting means are selected to provide a required boundary condition for the periphery of the piezoelectric device whereby the desired power coupling between the transducer and the load is provided.
