Abstract: A hydraulic clutch system for a motorcycle includes a foot pedal for engaging and disengaging a hydraulic clutch via hydraulic fluid in a first hydraulic fluid conduit and a hand clutch lever for engaging and disengaging the hydraulic clutch via hydraulic fluid in a second hydraulic fluid conduit. A solenoid or similar article switches the system between foot pedal and hand clutch lever control based on pressure in hydraulic lines extending from the foot pedal and hand clutch lever to the hydraulic clutch. A pressure switch, micro-switch or similar article communicates with, and activates the solenoid or other article to switch between lines.

Abstract: A shoe having a hinge member incorporated between a footbed toe plate and footbed arch plate allowing the shoe to be configured as a flat or heeled shoe. The footbed toe plate and footbed arch plate are rotatably joined via one or more hinge pins inserted through interlaced teeth of each plate. A spring-biased hinge lock extending between the plates is controlled by a spring-biased pin having a notch for selectively receiving the hinge lock such that the hinge lock disengages the footbed arch plate allowing the footbed arch plate to rotate relative to the footbed toe plate. The heel block includes a spring-biased heel lock extending into a removable heel and is controlled by a spring-biased pin having a notch for selectively receiving the hinge lock such that the hinge lock disengages the heel allowing the heel to be removed from the heel block.

Abstract: A hinge member incorporated between a footbed toe plate and footbed arch plate allowing a shoe to be configured as a flat or heeled shoe. The footbed toe plate and footbed arch plate are rotatably joined via one or more hinge pins inserted through interlaced teeth of each plate. A spring-biased hinge lock extending between the two plates is controlled by a spring-biased pin in positioned with a notch selectively receiving the hinge lock such that the hinge lock disengages said footbed arch plate allowing said footbed arch plate to rotate relative to said footbed toe plate. The heel block includes a spring-biased heel lock extending into a removable heel and is controlled by a spring-biased pin positioned with a notch selectively receiving the hinge lock such that the hinge lock disengages said heel allowing said heel to be freely removed from said heel block.

Abstract: A helmet lighting system includes a housing configured for attachment to a helmet wherein a lighting module includes a power source, plurality of light sources, signal receiving means configured to receive operational signals from one or more associated vehicles and a controller configured to selectively control the plurality of light sources responsive to said signal receiving means receiving said operational signals. In this manner, the lighting module may mimic brake lights and strobe lights associated with a motorcycle for example thereby rendering the motorcycle and rider more visible. Flexible ends of the housing allow the housing to attach securely to different helmet styles. Alternatively the lighting module may be integrated with the helmet. An emergency mode allows the helmet to be used as a warning device.

Abstract: A bone screw system is disclosed. The bone screw system allows a bone screw to be inserted into a bone via a guide set with a plurality of pins. After the bone screw is inserted, a head portion of an extension member attached to the bone screw remains external to the wound such that the bone screw can be tightened later without re-opening the wound. The bone screw system is applicable to bone fractures, bone fusions, Osteomonies and other bone connectivity procedures. After healing, the bone screw may be left in the patient by removing an upper portion or the screw may be removed with additional incisions and a local anesthetic.
