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.

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.

An improved storage unit of the type having an interior surface, an exterior surface, a floor, a pair of side walls, a front wall, a rear wall, and a roof. The roof is translucent, attaches without any puncturing thereto, and has overhanging eaves and bows with centers that are bowed thereat. A ventilation system allows the storage unit to benefit from storing in a climate controlled warehouse and provides airflow when the storage unit is stored outside. The rear wall has a roll-up door. The pair of side walls, the front wall, and the rear wall are attached from the exterior surface and the interior surface is smooth and non-abrasive. The floor is plastic undercoated plywood. Towing brackets front and rear provide a safe, strong, and secure method to attach a winch system of a transport system for maneuvering the storage unit on and off the transport system and to maneuver the storage unit with forklifts or pallet jacks in a yard or warehouse. Butyl tape seals the roof and all connecting panels and structures.
摘要:
Apparatus and methods are disclosed for determining internal engine characteristics using acoustic-vibration data. Exemplary such data are passive acoustic pyrometer data. Acoustic-vibrational frequencies emanating from a running engine are detected and compared to frequencies having known relationships to particular operating characteristics of the engine. In an example, the dominant frequency or other prominent frequency emanating from an internal-combustion chamber of a turbine engine is detected and used to determine the fuel-to-air ratio in the chamber. The determined data are used for performing adjustments or optimizations of engine performance, such as adjusting the fuel-to-air ratio as required or desired. In a similar manner, operating characteristics of other engines or engine-like environments, including furnaces and boilers, can be determined.
