  • Patent number: 6428035
    Abstract: A trailer comprises a front member, a center member, two wheel members, and an axle member. The front member is adapted to be removably attached to a towing vehicle. The center member is detachably connected to the front member. Each of the two wheel members include a wheel, and the axle member is detachably connected to the center member and to the wheel members. Channel sections can be attached to at least two of the members with the channel sections combining to create a channel that is adapted for receiving a cycle. The trailer can also include a ramp rotatably attached to the axis member. When the ramp is in a lower position, the ramp defines a path for communicating the cycle from the ground to the channel.

  • Patent number: 5530704
    Abstract: A communication system (100) provides simultaneous synchronization between a network controller (106) and numerous radio ports (102) using a single signaling channel. The network controller (106) includes a multiframe synchronization generator (208) which generates a multiframe synchronization packet (302) in response to a series of counters (212) and a timing reference (202). Each radio port (102) includes a multiframe synchronization detector (410) which verifies that the multiframe synchronization packet (302) is error free.
