Abstract: A non-conductive substantially buoyant-in-water hand tool comprising an elongated handle portion formed of non-corrosive, non-conductive material having a density greater than water and an elongated working tool connected to and extending axially from a proximal end of said handle portion. The handle portion has one or more outwardly opening cavities formed into a side surface of the handle portion. An elongated tubular sheath formed of material buoyant in water covers and sealingly encloses and forms one or more airtight cavities whereby the effective density of the hand tool is less than that of water.

Abstract: An electronic fish scale comprising a molded housing having upper and lower portions for supported hand grasping. An electronically controlled weight-sensing member and a viewable digital output screen are mounted within the housing. The output screen is electronically connected to the weight-sensing member whereby a weight held by gravity causes a digital numeric display on the output screen equal to the fish weight. A fish-engaging assembly extends downwardly from the weight-sensing member through an aperture formed in the bottom of the housing, and includes a pair of opposed c-shaped jaws. A longitudinally moveable jaw actuator is operably connected through a jaw control member via a rotation pin through diagonally extending aligned slots in the jaws whereby the jaws are opened when the jaw actuator is manually moved upwardly. A lower lip of a fish securely held and unhurt between the closed jaws will produce a digital display of the weight of the fish on the output screen.

Abstract: A method for generating multiple high-resolution PWM signals in which software interrupts are introduced at predetermined intervals to generate multiple high-resolution PWM signals from a conventional microprocessor. The software determines the purpose of the interrupt in an interrupt subroutine. An interrupt occurs when a compare register equals the timer. Another interrupt occurs when the timer overflows. The interrupts are the key to generating the multiple high-resolution PWM signals.

Abstract: In a preferred embodiment, a single-sheet applique for use in a multi-level display, including: a first portion formed in a single planar sheet of applique material; a second portion formed in the single planar sheet of applique material; at least a first segment formed in the single planar sheet of applique material and joining the first portion and the second portion; and the at least a first segment being arranged so as to permit the first portion and the second portion to be folded away from each other such that the first portion will lie in a plane different from a plane in which the second portion lies.

Abstract: A multi-sectioned coilable shaft which can be turned into a rigid shaft if desired, or be loosened to allow for the coilable storage of the shaft. The device has a handle and a cam lever fastened to one end of a cable. Along the cable are a plurality of cable spacers. A cable stop is fastened to the other end of the cable which captures the spacers on the cable and acts as the attachment mounting device. Adjustment is provided near the handle to allow for loosening of the cable or to allow for tensioning of the cable, when the cam lever is activated to draw the spacers tightly together to form a rigid shaft.
