  • Patent number: 6039395
    Abstract: A bicycle saddle includes two support members preferably supported by a base component which connects the saddle to a bicycle. The support members are positioned on the base component in a laterally spaced apart arrangement about a longitudinal axis of the saddle, leaving an open area between the support members. Each support member includes a nose portion and a back portion. The back portion includes a downwardly sloped front surface and a downwardly sloped aft surface. The front and aft surfaces meet at a ridge or transition surface which is preferably swept rearwardly along with the front surface. The nose portion of each support member extends from an inside edge of the front surface forwardly and generally parallel to the longitudinal axis of the saddle. In this configuration, the saddle supports the cyclist at the tuberosities of the ischium, along the junction of the back of the thigh and the buttocks, and somewhat along the junction of the inner thigh and the torso.

  • Patent number: 5799263
    Abstract: A public transit system uses a plurality of intracell vehicles to service transit requests in individual transit cells, and the transit cells are connected by intracell vehicles which travel between cell terminals located within the respective transit cells. The intracell vehicles are automatically dispatched by a dispatching system (12) which assigns each transit request to an intracell vehicle servicing a matching transit route or soft route comprising a geographical area and a route travel direction. The dispatching system (12) uses a process for selecting the most appropriate vehicle to handle a transit request where no prior route matches the request. This initial transit request then defines a new soft route for the vehicle to which it is assigned. Transit requests are preferably communicated to the dispatching system via a local telephone system and locations within the transit cell are defined by telephone numbers or other suitable identifiers.
