  • Publication number: 20040206573
    Abstract: A muffler exhaust tip for a vehicle having a muffler tailpipe includes a substantially hollow, cylindrical muffler tip member with an inboard end adapted to be affixed to the tailpipe and an outboard end. The hollow, cylindrical member is defined by an elongated outer sleeve and a coaxial, perforated inner sleeve which jointly define a baffle interspace therebetween. The inner sleeve carries a plurality of radially inboard protrusions to alter exhaust flow through the muffler exhaust tip. The perforated inner sleeve of the cylindrical member may define a pattern of holes. The baffle interspace may include a layer of fire retardant sound baffling material. The plurality of inboard protrusions define a helix extending through part of the inner sleeve in one embodiment. In another embodiment, part of the outer sleeve of the muffler tip includes a conical reducer such that the inboard end matches the dimensions of the tailpipe.

  • Patent number: 6758588
    Abstract: An optical fiber light includes a light source, a dispersion medium, a power supply, and at least one light tube disposed coaxially along a longitudinal axis of symmetry of the dispersion medium. The light source is integrated with the dispersion medium so that light emitted from the light source is received along the longitudinal axis of symmetry of the dispersion medium. The light tube distributes light along the length of the dispersion medium. Distributed light radiates from the light tube along the length of the dispersion medium.

  • Patent number: 6575002
    Abstract: The invention relates to a vehicle pedal lock having two elongated members that slide relative to each other. A stationary member has a base plate at one terminal end for placement on the floor of the vehicle. The stationary member defines a longitudinal channel through which slides the second, movable member. An upper pedal bracket supported by a yoke is mounted on the stationary member near the end of the longitudinal channel. The movable member has a lower pedal bracket at its terminal end. The movable member includes lock detents used to lock the movable member relative to the stationary member via a key-lock mounted to the stationary member. The key-lock includes a locking pin engageable with the locking detents. The pedal lock is adapted to capture and lock the vehicle pedal between the upper and lower pedal brackets such that the pedal may not be depressed.
