The invention involves the development of an autonomous street sweeper vehicle which can detect the presence of obstacles and pedestrians and is used to perform a variety of sweeping functions such as sweeping, vacuuming, blowing, scraping, and such types of functions on roads and a variety of different surfaces. This invention pertains to an autonomous street sweeper vehicle designed to follow routes comprising an autonomous vehicle that includes a drive by wire kit, a database storing the collection routes, a mechanism for detecting the curb, pedestrians, cars, and other road obstacles, a control system that controls the truck to follow routes while maintaining the truck at serviceable distances to the curb that improve the efficiency of the sweeper. The autonomous street sweeper convoy communicates with each other via radios or other methods and a lead vehicle which could be functional or non-functional accompanies several autonomous street sweeper vehicles as part of a convey. Each of the autonomous street sweeper vehicles performs a specific function. The vehicle speed and settings of the cleaning equipment are adjusted based on road hazards that come across the path of the autonomous street sweeper vehicles.

An electro-hydraulic actuation system for a sprayer comprises a hydraulic system, a hydraulic actuator, an electric actuator and a sprayer. The hydraulic system is for pressurizing a hydraulic fluid. The hydraulic actuator is powered by the hydraulic system. The electric actuator controls actuation of the hydraulic actuator by the hydraulic system. The sprayer is actuated by the hydraulic actuator.

A differential case (23) is therein provided with a plurality of rotating discs (38) that are spline-coupled to an outer peripheral side of aright side gear (35), and a plurality of non-rotating discs (39) that are respectively arranged between the respective rotating discs (38) and are non-rotatable relative to the differential case (23) and are movable in a left-right direction. A pressure ring (43) that presses the non-rotating discs (39) toward the rotating discs (38) is disposed between a right retainer (41) positioned in the right side gear (35)-side and the non-rotating disc (39). The right retainer (41) is therein provided with a piston accommodating part (41D) in a position facing the pressure ring (43) in the left-right direction. The piston accommodating part (41D) is therein provided with a piston (46) that is displaced by hydraulic pressure to press the non-rotating discs (39) against the rotating discs (38) through the pressure ring (43).

A system and method in a building or vehicle for an actuator operation in response to a sensor according to a control logic, the system comprising a router or a gateway communicating with a device associated with the sensor and a device associated with the actuator over in-building or in-vehicle networks, and an external Internet-connected control server associated with the control logic implementing a PID closed linear control loop and communicating with the router over external network for controlling the in-building or in-vehicle phenomenon. The sensor may be a microphone or a camera, and the system may include voice or image processing as part of the control logic. A redundancy is used by using multiple sensors or actuators, or by using multiple data paths over the building or vehicle internal or external communication. The networks may be wired or wireless, and may be BAN, PAN, LAN, WAN, or home networks.

A vehicle includes a frame including a front frame part and a rear frame part. A single front wheel is rotatably connected to the front frame part. A single rear wheel is rotatably connected to the rear frame part. Each of the front wheel and the rear wheel is adapted to have a cylindrical shape in top view when the vehicle is traveling in a straight direction, and at least one of the front wheel and the rear wheel is adapted to expand and have a frustoconical shape in top view in a turning condition of the vehicle.

This disclosure is generally directed to systems and methods for automatically securing a vehicle such as a police truck or an emergency response vehicle and/or the contents of the vehicle after a bailout by the driver. In one exemplary method, a computer is configured to use a sensor system to detect that a driver of a vehicle has bailed out of the vehicle. Based at least in part on detecting that the driver has bailed out of the vehicle, the computer can execute operations such as automatically locking a door of the vehicle, logging out a computer located in the vehicle, locking a first component inside the vehicle such as a gun vault, and/or disabling an operation of another component in the vehicle such as a trunk release or an ignition switch.

A zero emissions electrically powered haul truck is disclosed. The haul truck has a 40 metric ton hauling capacity and a form factor that allows the truck to travel through underground mines. The truck also includes a primary battery assembly that is externally mounted along the front and sides of the truck.

An autonomous vehicle is disclosed. The vehicle comprises a chassis, two or more drive wheels extending below the chassis, a drive motor housed within the chassis for driving the drive wheels, and a payload surface on top of the chassis for carrying a payload. An illumination system, for emitting light from at least one portion of the chassis, is mounted substantially around the entire perimeter of the chassis. The illumination system may be implemented using an array of light-emitting diodes (LEDs) that are arranged as segments. For example, there may be headlight segments on the front left and front right corners of the chassis.

A self-monitoring and self-controlling smart irrigation system is provided. The smart irrigation system may include a plurality of tower control units, which tower control units include one or more processors, one or more memory units, and communication circuitry. The tower control units may be configured to determine one or more operational conditions of the smart irrigation system, to communicate to other tower control units the operational conditions, and to make adjustments based on the operational conditions. The tower control units may be configured for expedient and efficient replacement and maintenance in that they may be readily detachable from the smart irrigation system.
