Abstract: A programmable array logic circuit whose temporary memory circuitry employs single bit non-volatile ferromagnetic memory cells. The ferromagnetic memory cells or bits store data even when there is no power provided to the circuitry, thus saving power during operation of the programmable logic circuitry, and ensuring that there is no loss of the data should there be a temporary power shut down. Additionally, the ferromagnetic cells provide for indefinite number of switching actions on the data without degradation to the capacity to store data therein. The invention provides an integrated circuit, comprising a programmable logic circuit array having product lines and input lines therein, and a storage register circuit. The storage register circuit has a ferromagnetic bit and sensor coupled to store a remnant control signal and an output transistor, coupled to be responsive to the remnant control signal on its gate, and coupled between an input and product line.

A frame attachment member is secured to an underside, typically the belly pan, of a front portion of a snowmobile, upon which a rack frame is removably attached. The rack frame includes at least two uprights, with a cradle formed into an upper portion of each upright, for secure placement of a snowboard. The snowboard is secured to the rack frame with a tie-down strap at each cradle.

Abstract: A boat mounted hunting blind to aid hunters in hunting game, particularly water fowl; wherein, at least two pontoons are connected together, preferably in parallel orientation, by way of a bridging platform. Above the platform there is hingedly attached a collapsible canopy, preferably camouflaged in design, within which the hunter may be concealed in a seated or standing position while scouting and shooting game. Above the canopy there is removably attached a detachable roof, preferably camouflage in design, for providing weather protection for the hunter and further concealment.

Abstract: A trolling motor steering linkage system with motor steering and speed controls mounted adjacent to a central or midship portion of a boat for ease of one-hand operability. The steering linkage system is mounted to a top surface or hull of a boat via a propeller tube, secured to a transom which spans the width of the craft and provides support for the propeller tube. A motor control head controls the direction and the speed of the trolling motor with an integrally attached grip throttle. A roll bar is attached to the motor control head, which roll bar is supported at a raised elevation from the mounting surface of the boat by roll bar stantions. The roll bar is further connected to a linkage rod, which linkage rod is connected to the propeller tube for rotating the propeller tube, with attached trolling motor and propeller, and thereby steers the boat.

Abstract: The invention generally related to registers or flip-flop circuits. More particularly, the present invention refers to the use of non-volatile ferromagnetic memory cell to store binary data in a register or flip-flop circuit. It is an advantage of the invention to have a flip-flop with a ferromagnetic memory cell or bit to store data even when there is no power provided to the circuitry. Thus, saving power during operation of any associated circuitry, and ensuring that there is no loss of the data should there be a temporary power shut down. Additionally, the ferromagnetic cells provide for indefinite number of switching actions on the data without degradation to the capacity to store data therein, or eliminating “write fatigue”.

More particularly, the present invention uses a non-volatile ferromagnetic memory cell to temporarily store binary data. It is an advantage of the invention to have the ferromagnetic memory cells or bits to store data even when there is no power provided to the circuitry, thus saving power during operation of the programmable logic circuitry, and ensuring that there is no loss of the data should there be a temporary power shutdown. Additionally, the ferromagnetic cells provide for indefinite number of switching actions on the data without degradation to the capacity to store data therein, thus eliminating “write fatigue”. The invention provides an integrated circuit, comprising a programmable OR array (24), a programmable AND array (28), coupled to the programmable OR array, and a macrocell output circuit (22).

Abstract: There is a walking cane, for supporting and balancing a user, and allowing a user to retard forward motion. The walking cane includes a base, having a wheel rotatably coupled thereto. The cane further includes a braking member, coupled to and positioned relatively above the base, having a contact portion that contacts the wheel to retard the wheel's rotation when a threshold downward force is applied to the cane.

Abstract: A lifting device made of a single piece of a flexible material, substantially forming a loop, is disclosed. The flexible material has a first and second edge, a fold between the first and second edge, such that the first edge rests substantially atop the second edge, and a seam securing the first edge to the second edge. A first handle is formed by a first end of the loop, and a second handle is formed by a second end of the loop, opposite the first end of the loop. A flexible support piece is coupled substantially within the loop, between the first and second end of the loop. A method of using a person lifting device is also disclosed. The first step of the method is to provide a lifting device. The lifting device includes a single piece of a flexible material, substantially forming a loop.

Abstract: A marking composition for placing a temporarily visible mark on a surface. The composition includes a paint base and a pigmented colorant. The pigmented colorant is dispersed within the paint base, and has characteristics that cause the mark to progressively become substantially invisible upon exposure to UV light. Additives, such as UV absorbers and anti-oxidants may be included to alter the rate at which the mark becomes invisible. The pigmented colorant may be a dispersion of dyed melamine-toluenesulfonamide-formaldehyde polymer in a mixture of alkyl based resins and aliphatic hydrocarbons. The colorant may be about 2 to 30 parts by weight of the composition.

Abstract: The device for the formation of skeined sections on thin metallic wires is of the type in which the wire to be skeined extends from an inlet point (9) to an anchor point (15) and is placed under traction by a wire-tightening device (2). A branch of said wire emerging from said anchor point is sent to a wire-tightening device (8) controlled by an electronic control system which controls the skeining operation. The wire-tightener being present the following parts: a pulley (28) connected to an electromagnetic brake (29) with electromagnetic hysteresis; a second pulley (27) located above the first pulley (28) sensitive to the load bearing and sending a signal signifying the load to the control system which regulates the braking action of the brake.
