  • Patent number: 9436182
    Abstract: Aspects of the present disclosure relate to a vehicle for maneuvering a passenger to a destination autonomously. The vehicle includes one or more computing devices and a set of user input buttons for communicating requests to stop the vehicle and to initiate a trip to the destination with the one or more computing devices. The set of user input buttons consisting essentially of a dual-purpose button and an emergency stopping button different from the dual-purpose button configured to stop the vehicle. The dual-purpose button has a first purpose for communicating a request to initiate the trip to the destination and a second purpose for communicating a request to pull the vehicle over and stop the vehicle. The vehicle has no steering wheel and no user inputs for the steering, acceleration, and deceleration of the vehicle other than the set of user input buttons.

  • Patent number: 7409286
    Abstract: A process to interchange the “stop and go” driving behaviour of the traffic with a “stop and wait, then go later without stopping” driving behaviour, consisting on a partitioning of the congested route in segments through pre-installed stop and go signals marking the limit of segments to give a stop to the vehicles of the first part and later another stop to the vehicles of the second part of the divided congestion and so on, to permit the liberation of the front conflict part of the way, turning the first signal to go at the appropriate moment and then turning the second signal to go and so forth until the vehicles of every segment after waiting in standstill go without stopping re-stabilizing the normal traffic flow. The waiting time will be announced simultaneously to avoid the uncertainty of waiting time.

  • Patent number: 7303169
    Abstract: An overhead running vehicle 10 uses an absolute position sensor or an encoder to detect its own position. The overhead running vehicle 10 then reports its own position and state to a system controller 14 via a communication line also used as an electricity feeding line. Further, the overhead running vehicle 10 intercepts reports from other overhead running vehicles 10 to avoid collisions or deadlocks. The system controller 14 and each overhead running vehicle 10 can determine the positions and state of other overhead running vehicles 10. This enables the system to be efficiently operated.

    Abstract: A system and a method for moving cartridges between individual cartridge libraries of a multi-library system. The system includes one or more transport robots operating on one or more guide structures. The transport robots carry the cartridges independently of all individual libraries, except the sending and receiving libraries. Load ports at each library transfer the cartridges between the transport robots and the library's robotic arm. The load ports can also hold the cartridges allowing for asynchronous operations between the transport robots and sending/receiving libraries. The guide structures may be routed through one, two or all three dimensions allowing individual library placements to account for walls, columns, floors, ceilings, and other physical obstacles.
