  • Patent number: 9259370
    Abstract: A collapsible wheelchair (CW) may be relatively small and lightweight and may be adapted to be easily collapsed/folded into a callable faint, allowing for easy storage, transport and use. The CW may be adapted to be collapsed/folded and expanded/unfolded in a series of simple steps, executable with one hand, by a person in a seated position, allowing for independent use even by a user with limited physical capabilities. The CW may have a relatively small width, allowing for access into constricted spaces. The rear and interior space between its large wheels may be unobstructed, leaving an unobstructed inner width, allowing the CW to be maneuvered in reverse over standing objects, such as a standard toilet. The seat of the CW may be equipped with a trap door, to allow the use of a toilet while seated on the CW. The rim may be beneath the seat for cleanliness.

  • Patent number: 9242690
    Abstract: An interchangeable colored bicycle has a bicycle framework with a main bicycle frame component part, a handlebar stem component part, and a wheel fork component part. Clear transparent tube members enclose and circumscribe these component parts. Free-flowing, colored liquids fill the interior spaces between the tube members and the component parts. The colored liquids in each interior space are different, thus allowing the bicycle to assume multiple colors. The free-flowing liquids can be drained from the tube members and different colored liquids can be poured into the interior spaces to change the colors of the bicycle.

  • Patent number: 9238496
    Abstract: Vibration generators are provided on a vehicle to give vibration to the body of an occupant in response to outside information inputted from the outside of the vehicle, or vehicle information outputted from an in-vehicle system. The vibration generators are installed under the seating faces or inside the back of the occupant seats, or in the side wall surface of a fuel tank. The vibration generators are driven by information on predetermined contents among outside information obtained by two-way radio communication with another vehicle using radio communication equipment. The vibration generator provided in the occupant seats can be operated as speaker means producing deep bass sound in response to an audio signal of an in-vehicle audio unit. The resulting configuration enables information to be transmitted to the occupant of the vehicle by vibration given to his/her body, rather than being transmitted audibly or visually.

  • Patent number: 9216647
    Abstract: A fuel tank system which has a revised mounting system and a revised location for the fuel system and fuel tanks to improve crashworthiness of the vehicle by reducing the occurrence of tank failure, fuel spillage, fire and/or explosion during and after a collision or similar event, while still providing a sufficient range for the vehicle. The fuel tanks are protected from damage from the side, bottom and between the tanks. The fuel tank mounting system also allows the energy associated with an event to be managed, such as by allowing the fuel tanks to be pushed or moved downwardly and/or laterally by the energy of the impact of a collision or similar event to a position in which the fuel tank is either out of the path of the impact or protected by the chassis or frame of the vehicle.

  • Patent number: 9168972
    Abstract: A control device, for the rear shock absorber of a bicycle, includes a first air chamber, a second air chamber, a third air chamber, an auxiliary air chamber, and a sliding rod. An air piston is arranged inside one of the first, second and third air chambers. However, those air chambers are respectively provided with an air hole communicating with the auxiliary air chamber. The sliding rod is configured with air tight rings, which are arranged top-to-bottom and tightly touch the inner wall of the auxiliary air chamber. Moreover, the sliding rod is provided with grooves between the air tight rings, so that the axially movement of the sliding rod may manage the first, second and third air chambers to be disconnected or to communicate with one other via the grooves to adjust the damping coefficient of the rear shock absorber.
