Abstract: Master cylinder assemblies, particularly for operation of the brake or clutch of motorcycles or other ATVs, are susceptible to a reduction in pressure due to the introduction of unwanted gases within the hydraulic lines. As a result, the brake or clutch system may not operate as designed. The present disclosure describes master cylinder assemblies that include one or more fluid separators, with a separator at least at the compensating port of the fluid reservoir to inhibit or prevent air or other gases from entering the piston channel through the compensating or inlet ports.

Abstract: A brake assembly has a lever configured to press a knee against a pushrod of a piston of a master cylinder assembly. The knee is configured to receive removable inserts that allow a user to modify the angle at which the lever activates the master cylinder assembly. The master cylinder assembly can include protrusions on the outer surface of the cylinder to protect the cylinder from impact damage.

Abstract: A protective cover for a hydraulic clutch or brake assembly is provided. The protective cover can have a pressure tube portion sized to fit over at least a portion of a master cylinder of the hydraulic brake or clutch assembly. The protective cover can further include a reservoir portion sized to fit over at least a portion of a reservoir of the hydraulic brake or clutch assembly. The reservoir portion can extend away from the pressure tube portion along a second longitudinal direction. The protective cover can further include a pivot portion that extends away from the pressure tube portion along the first longitudinal direction. The pressure tube portion can include a plurality of ribs that reduce or eliminate the master cylinder of the hydraulic clutch or brake assembly becoming damaged or deformed due to rocks or debris impacting a front face of the protective cover.

Abstract: A system and method for detecting the presence or measuring the quantity of liquid within a tire assembly is disclosed. The system includes an energy source, an energy detector, a controller, and a determination indicator. The energy source is configured to direct energy towards the liquid, with the energy interacting with the liquid. The energy detector is configured to detect at least a portion of the energy after having interacted with the liquid and to generate signals indicative of the detected energy. The controller is configured to receive user input and to control at least one of the energy source and the energy detector in response to the user input. The controller is further configured to receive the signals generated by the energy detector, to respond to the signals by generating a determination regarding the liquid within the tire assembly, and to generate a signal indicative of the determination.

Abstract: A wheel brake for a bicycle or other vehicle has a pair of pivoting arms. Each arm is configured to support a brake pad. A first arm pivotally supports a cam. A second arm defines a cam surface and a cable guide. The cam has a first end for mounting of a cable and a second end having a roller which rests on the cam surface. When the cable is actuated, the cable pulls the first end of the cam, causing the cam to pivot and causing the second end of the cam to roll along the cam surface. Force applied by the cam compresses the arms, causing associated brake pads to move inwardly into engagement with the wheel. The brake is compact and efficient in design.

Abstract: A collapsible control lever suitable for use on a motorcycle includes a handlebar mount, an intermediate section and a lever section. The intermediate section and lever section are capable of rotation with respect to the handlebar mount between a relaxed position and an actuated position in order to provide control lever functions, such as disengaging a manual clutch. The lever section is capable of rotation with respect to the intermediate section between a normal position and a fully deflected position in order to avoid damage in the event of the motorcycle overturning. The lever section may be biased to its normal position.

Abstract: A modified toggle link assembly for a lever action rifle including a modified slide channel that, in at least one embodiment, produces a shorter lever stroke and smoother lever cycle. The modified toggle link may also include a modified profile which defines a hump on an upper surface of the rearward link of the toggle link and a corresponding recess on the forward link. This hump allows for the modified geometry of the slide channel. The slide channel may be a modified straight path or a compound, or non-linear path.

Abstract: A bicycle seat clamp arrangement including a bicycle seat having a mounting beam extending lengthwise on an underneath side of the bicycle seat and defining a first surface. A clamp assembly is configured to apply a clamping force to the mounting beam and defines a second surface. The first and second surfaces are configured to interlock in order to inhibit relative fore and aft movement of the bicycle seat and the clamp arrangement. In one arrangement, the surfaces comprise a plurality of interlocking gear teeth. In another arrangement, the surfaces comprise a corresponding plurality of projections and depressions. The first and second surfaces may cooperate to form a wedge configuration to inhibit rocking of the bicycle seat relative to the clamp assembly.
