Abstract: A bow sight automatically corrects and compensates for various dynamically changing aiming, shooting, and/or environmental conditions. The bow sight can perform situation-specific aim evaluations and corrections to correct or compensate for situation-specific shooting and environmental factors, at a given time and on a per-shot basis. The bow sight includes integrated sensor-type devices, such as a range finder, an inclinometer, and an anemometer, which detects values of situation-specific shooting and environmental factors and communicates such detected values with a processor or other control device. The processor uses the situational specific data, as well as bow and arrow performance data, and data from shot calibrations, to calculate precise vertical and horizontal aim compensations required to accurately hit the desired target point.

Abstract: A device for holding archery bows and/or other hunting accessories is provided. The hunting accessory holding device includes a base member that attaches to a mounting substrate such as a tree, an arm assembly that is configured to hold the archery bow, and a lift mechanism that connects the arm assembly to the base member. The lift mechanism automatically retracts the arm assembly upwardly, from an extended position to a retracted position, when the bow is removed from the arm assembly, thereby removing the arm assembly from the hunter's view and way. The lift mechanism can include a spring that provides a retracting force for moving the arm assembly. As desired, the lift mechanism can also provide an adjustable or variable braking force that opposes the retracting force and enables the hunter to determine a rate of arm retraction, as desired.

Abstract: A fencing system is constructed with thin-walled generally rectangular tubing. The large cross-section of the rectangular tubing provides significant structural strength. The posts can also be formed into rectangular cross-sections to achieve similar cross-sectional strength. The posts are provided with openings for the rails to be inserted. A compliant grommet is provided in each opening and allows for articulation in any direction, isolates the rail from the post to prevent metal-on-metal contact, provides cushioning to the rails upon impact, silences the rails in heavy wind, electrically isolates each fence section and centers the rail in the post opening. A system of clips or spring loaded lock pins attach to the ends of the rails allow the rails to be easily inserted into the posts, but prevents their removal.

Abstract: A composite tubing system is formed from an outer decorative tube along with inner reinforcing tube(s) that are progressively shorter and smaller reinforcing members having greater composite thickness and strength at the location of highest bending moment. The strength and thickness may be maximized toward the center of a beam, such as a fence rail or hand rail, that is subject to maximum bending moments at its center, or may be maximized toward one end of a cantilevered beam, such as at the base of a fence post.

Abstract: A golf car having a hydraulic fluid brake system. The hydraulic fluid brake system is implemented as a disk brake system which is responsive to hydraulic fluid pressure generated from a master cylinder. A brake pedal and associated linkage provides input to a master cylinder to generate a hydraulic fluid pressure to control a brake caliper assembly. The brake pedal has a range of travel, where a first portion of the range defines a service mode of operation and a second portion of the range defines a parking mode of operation. In the parking mode of operation, the brake pedal and linkage engages a detent to maintain application of the brake to provide a parking mode of operation. An accumulator in the brake system provides an input force to maintain hydraulic fluid pressure sufficient to retain a parking mode of operation.

Abstract: A connector for a steel fence or the like is provided. The connector is formed from a single, cast metallic piece yet can mount one or multiple adjacent rail sections on a post using only a single mount or piece of hardware attaching the connector to the post. It has a vertical throughbore for receiving the post and a horizontal throughbore that intersects with the vertical throughbore at approximately its mid-point. Each end of the horizontal throughbore forms a receptacle for receiving an end of an associated rail section. A grommet is mounted in each receptacle for centering the associated rail section end in the receptacle, locking the rail section from rotation. The grommet also accommodates limited pivoting of the rail section relative to the connector in both the horizontal and vertical planes, hence, accommodating both inclination and directional changes in the fence.

Abstract: Precision castings requiring a fine finish and having complex internal geometries can be produced by casting a semi-solid thixotropic metal alloy within or about a melt-away metal component in the form of a core and/or a die insert that has a lower melting point than the solid-to-semi-solid transition temperature of the thixotropic alloy The thixotropic alloy may be cast, e.g., by thixocasting, rheocasting, sub liquidus casting. Then, after the alloy solidifies to form a casting with a captured melt-away component, the component is melted from the casting, preferably using a liquid bath. Process robustness, speed, and versatility can be enhanced by coating the component with a thin, uniform, abrasion-resistant, and thermally resistant coating that prevents excessive heat from being transferred to the component from the alloy and that prevents the component from alloying with the casting.

Abstract: A hydraulic brake system includes a hydraulic accumulator that stores much of the energy generated upon brake pedal depression. The stored energy can be used to maintain the brakes in their fully engaged state and to help return an applied brake pedal to its released position, in which case return fluid flow to the master cylinder is damped to avoid undesirable severe kickback of the brake pedal. A booster is provided to automatically boost the energy storage capacity of the accumulator during normal brake and hold cycles in order to provide sufficient energy accumulation to compensate for relatively severe pressure drops occurring, e.g., during prolonged periods of storage at extremely low temperatures. The booster may comprise an indexing arm that is acted upon by the system's brake pedal to selectively move a variable thickness spacer on the indexing arm into and out of engagement with the accumulator.

Abstract: A hydraulic brake system (50) for a vehicle such as a golf car or the like uses the same brakes (52) and same brake pedal (80) for both service braking and park and hold braking. The brakes (52) are selectively engaged, locked in their engaged position, and released using an integrated control assembly including a brake pedal (80), an accelerator pedal (82), and a brake pedal locking mechanism (84). The brake pedal locking mechanism (84) is configured to automatically latch the brake pedal (80) in a locked position thereof and to automatically unlatch the brake pedal (80) from its locked position upon either subsequent movement of the brake pedal (80) into an overtravel position or subsequent actuation of the accelerator pedal (82). In addition, a hydraulic accumulator (62) stores part of the energy generated upon brake pedal depression and consequent manual actuation of a master cylinder (60) of the system to maintain the brakes (52) in their fully engaged state when the brake pedal (80) is latched.

Abstract: A golf car having a frame supported on a plurality of wheels and a bracket member fixedly coupled to the frame. A brake pedal assembly and an accelerator pedal assembly are pivotally coupled to the bracket member such that the brake pedal and accelerator pedal are disposed in a generally suspended position behind the cowling, rather than a floor mounted position. This arrangement maximizes the ergonomic placement of the pedals, and minimizes corrosion due to exposure to moisture and chemicals and damaged caused by contact with brush and debris.

Abstract: A golf car having a frame supported on a plurality of wheels, a pedal system, and a pedal arm assembly operably coupled to the pedal system for actuating either a brake system or drive system of the golf car. The pedal arm assembly includes an arm pivotally coupled at least indirectly to the frame and a pedal member extending therefrom. The pedal arm assembly is injection molded such that the arm and the pedal member are integrally molded as a single member that is generally resistant to corrosion. The pedal arm assembly may also include an internal reinforcement member that is encapsulated within the pedal arm assembly for improved structural rigidity.

Abstract: A brake caliper includes a cast metal housing having a bore extending perpendicularly to a disc located adjacent the housing, at least one piston slidably mounted in the bore, and a brake pad mounted on the piston. A coolant passage, formed through the housing in liquid isolation from the bore, coupled to a source of liquid coolant. The coolant passage is a single-pass passage having a coolant inlet and a coolant outlet. The coolant passage is configured to minimize turbulence of coolant flowing therethrough while still promoting effective heat transfer to the flowing coolant from the piston and brake fluid. Preferably, the housing is an aluminum housing formed from a single casting.
