    摘要: An autonomous vehicle and systems having an interface for payloads that allows integration of various payloads with relative ease. There is a vehicle control system for controlling an autonomous vehicle, receiving data, and transmitting a control signal on at least one network. A payload is adapted to detachably connect to the autonomous vehicle, the payload comprising a network interface configured to receive the control signal from the vehicle control system over the at least one network. The vehicle control system may encapsulate payload data and transmit the payload data over the at least one network, including Ethernet or CAN networks. The payload may be a laser scanner, a radio, a chemical detection system, or a Global Positioning System unit. In certain embodiments, the payload is a camera mast unit, where the camera communicates with the autonomous vehicle control system to detect and avoid obstacles. The camera mast unit may be interchangeable, and may include structures for receiving additional payload components.

    摘要: Systems and methods for switching between autonomous and manual operation of a vehicle are described. In one embodiment, there is a mechanical control system that receives manual inputs from a mechanical operation member to operate the vehicle in manual mode. There is further an actuator that receives autonomous control signals generated by a controller. When the actuator is engaged, it operates the vehicle in an autonomous mode, and when disengaged, it operates the vehicle in manual mode. In another embodiment, there is an E-Stop system to disengage systems that cause the vehicle to move, such as the engine, while still leaving power in the systems that do not cause the vehicle to move. There is a method for autonomous mode starting of a vehicle, comprising receiving a signal indicating autonomous mode, determining that a parking brake lever is set and the brakes are engaged, disengaging the brakes while maintaining the lever in the set position, and engaging in autonomous mode. There is a safety system with a mechanical bias to suppress moveable systems of the vehicle, comprising a clutch that releases the mechanical bias to permit movement of the moveable system when the clutch is engaged. In another embodiment a system comprises a mechanical linkage with a restoration member that permits control of an operation system of the vehicle by a remote operation member when the restoration member is engaged. There is also an actuator that prohibits control of the operation system by the remote operation member when the actuator is engaged.

    摘要: Systems and methods for interruptible autonomous control of a vehicle. Autonomous control is achieved by using actuators that interact with input devices in the vehicle. The actuators (e.g., linkages) manipulate the input devices (e.g., articulation controls and drive controls, such as a throttle, brake, tie rods, steering gear, throttle lever, or accelerator) to direct the operation of the vehicle. Although operating autonomously, manual operation of the vehicle is possible following the detection of events that suggest manual control is desired. Subsequent autonomous control may be permitted, permitted after a prescribed delay, or prevented.

    摘要: System and method for multi-modal control of a vehicle. Actuators (e.g., linkages) manipulate input devices (e.g., articulation controls and drive controls, such as a throttle, brake, accelerator, throttle lever, steering gear, tie rods, or transmission shifter) to direct the operation of the vehicle. Behaviors that characterize the operational mode of the vehicle are associated with the actuators. After receipt of a mode select command that dictates the operational mode of the vehicle (e.g., manned operation, remote unmanned tele-operation, assisted remote tele-operation, and autonomous unmanned operation), the actuators manipulate the operator input devices, in accordance with the behaviors, to affect the desired operational mode.

    摘要: The present invention utilizes external synchronization to generate a completely standardized or functionally standardized optical transmission unit of level k (OTUk[V]) signal providing less jitter and wander build-up through a network of optical transport network (OTN) elements. This increases noise margins of transported signals and payloads. The present invention provides stratum-level synchronization utilizing a standards-based approach. In one embodiment of the present invention, rate adapters are included to provide m/n scaling of OTUk[V] signals to rates common in SONET and SDH synchronizers to provide line and loop distribution of timing through OTUk[V] signals. The present invention provides a choice of external synchronization sources including building integrated timing source (BITS), line, and loop timing sources. In another exemplary embodiment, the present invention provides multiple external references and automated timing protection switching for redundancy and reliability.

    摘要: A method of managing water is provided, in which the water is discharged from an aggregate plant, and therefore contains a large number of fines. The water is first passed through a mesh screen to remove large particles and then collected in a sump. From the sump the water is pumped to a centrifugal cyclone, where some of the fines are separated from the water. Flocculent is then applied to the water, before the water is collected in a pond.
