Abstract: A fishing net support assembly for releasably securing a pole of a fishing net to a boat includes a boat mount and a pole mount, which are configured to be mounted onto a hull of the boat and to a pole of a fishing net, respectively. A first mating member and a second mating member are attached to the boat mount and to the pole mount, respectively. Upon mating of the second mating member to the first mating member, the pole is positioned in a horizontal plane and a receiving net of the fishing net and a catch within the receiving net are positioned in the water and are rotatable within the horizontal plane.

Abstract: A fishing net support system includes a boat mount configured to be mounted onto a boat hull. A linkage is attached to the boat mount. A receiver can receive a pole of a fishing net. The receiver is mounted on the linkage, such that the linkage allows pivoting between the boat mount and the receiver within a vertical plane.

Abstract: A shaft comprises a hardened outer metallic layer having a first hardness level with a generally uniform radial depth. A first strip extends in a generally longitudinal direction in the outer metallic layer. The first strip has a second hardness level different from the first hardness level. A second strip in the outer metallic layer has the second hardness level. The first strip and the second strip are spaced apart from each other over at least a longitudinal region. A sensor senses an angular difference between a first magnetic field associated with the first strip and a second magnetic field associated with the second strip. A data processor references an established relationship between a position of the shaft and the angular difference between magnetic fields associated with the first strip and the second strip to detect a Position of the shaft with respect to a reference point.

Abstract: An improved proximity sensing circuit and method is provided. In particular, the proximity sensing system includes an improved controller comprising a programmable logic device (“PLD”). In one particular aspect of the invention, the controller includes a field programmable gate array (“FPGA”) controller. In general, the proximity sensing system measures the AC and DC resistances of a proximity sensor and a precision resistor and, from these measured values, calculates a compensated resistance. The compensated resistance may be used to determine the gap. The measured AC and DC resistances of the proximity sensor may be used to perform a self diagnostic on the sensing system and aid in determining a system fault.

Abstract: A battery system includes a battery with a pair of terminals extending from one side of the battery case, and a tray-like battery holder. The terminals have hollow sockets inserted therein which are engaged by posts extending from conductive plugs that extend through an end wall of the holder. A threaded connection is formed in the plug and opens to the outside of the holder. Alignment posts are formed in the holder to be disposed within cylindrical wells in the bottom of the battery case and ensure proper alignment of the battery in the holder. A hinged latch is formed in the holder and engages a projection on the battery case. When in place in the holder, the battery case rests on resilient pads located on a floor of the holder.

Abstract: The apparatus of the present invention provides a cover for venting gases from thin metal film battery cells having vents disposed at the center of one end of the cells. The vents comprise cylindrical wells that recess into, and substantially fill, the top portions of battery cell cavities within a battery housing. The cavities are sized to hold the battery cells securely and are configured to provide an electrical serial connection. The wells include pipes which extend outward from the bottom of the wells and lead from openings in the bases of the wells. The openings in the pipes are covered with flexible valve caps and well lids cover the wells. The center point arrangement of the recessed wells permit gases from the battery cells to escape through the openings, yet restrict the electrolyte from exiting the housing.

Abstract: A portable, tree mounted seat assembly includes a substantially rigid mounting bar embedded into a tree, a substantially rigid seat supporting frame removably secured to the mounting bar, and a seat mounted to swivel on the seat supporting frame. The mounting bar includes two 90 degree bends to form an anchoring segment embedded into the tree, a vertical medial segment and a horizontal handle segment. An elongate receiving sleeve is fixed to the medial segment, vertically disposed, and open at least at the top to receive an elongate coupling sleeve of the supporting frame for a nesting engagement with the receiving sleeve. The handle segment underlies the receiving sleeve, to support the coupling sleeve by gravity when the coupling sleeve is nested within the receiving sleeve. A seat is pivotally mounted to a distal region of the supporting frame.
