A start-stop system 100 for a working vehicle is provided. The start-stop system comprises a body 102; a push button 104 configured for linear movement relative to the body between a first button position and a second button position; and a rotatable sleeve 108 positioned radially outboard of the push button and configured to rotate between a first sleeve position and a second sleeve position. The start-stop system is configured to transition to an enabled state when the rotatable sleeve is moved from the first sleeve position to the second sleeve position. The start-stop system is configured to activate a prime mover of the vehicle when the start-stop system is in the enabled state and the push button is moved from the first button position to the second button position. The rotatable sleeve is biased to automatically return from the second sleeve position to the first sleeve position.

A load dampening system 60 for a working vehicle is provided. The load dampening system comprises a load handling hydraulic actuator 28 configured to support a load carried by the working vehicle and an accumulator apparatus 100 for storing pressurised hydraulic fluid. The accumulator apparatus is selectively connectable to the load handling hydraulic actuator to act as a compliant element which dampens pressure fluctuations in the load handing hydraulic actuator. The load dampening system also comprises a control system 70 configured to adjust a compliance of the accumulator apparatus to adjust the extent to which the accumulator apparatus dampens pressure fluctuations in the load handling hydraulic actuator.

An apparatus for use with a plurality of robotic vacuum cleaners, the apparatus comprising a plurality of receiving spaces each configured to receive at least one robotic vacuum cleaner, wherein each of the receiving spaces comprises: a shelf comprising an upper surface on which a robotic vacuum cleaner can be located, wherein the shelf is angled relative to a horizontal plane when the apparatus is positioned on a horizontal surface; one or more locating formations positioned such that a robotic vacuum cleaner located on said angled shelf is urged towards the one or more locating formations by gravity; and one or more wheels, rollers or friction-reducing elements for transporting the apparatus.

A working vehicle (10) is provided comprising: at least one hydraulic actuator (102) for actuating a non-steering function of the working vehicle; and a steering system (120) comprising one or more steering cylinders (122), a primary pump (124) for supplying hydraulic fluid to the one or more steering cylinders in a normal steering mode, and a back-up system (130) for supplying hydraulic fluid to the one or more steering cylinders in a back-up steering mode. The back-up steering system comprises a secondary pump (134) for providing an alternative hydraulic fluid source for the one or more steering cylinders. The working vehicle comprises a control system (140) configured to simultaneously direct a flow of hydraulic fluid from the secondary pump to the one or more steering cylinders and to the at least one hydraulic actuator for simultaneously steering and actuating the non-steering function of the working vehicle.

Aspects of the present disclosure relate to an electrohydraulic system 10 for a working machine. The system comprises a pilot hydraulic circuit 20 comprising a pilot pump 22 and one or more pilot pressure sensors 28A, 28B selectively coupled to the pilot pump via one or more user-operable pilot control valves 24A, 24B. The system also comprises a main hydraulic circuit 50 comprising a main hydraulic pump 52 and a hydraulic actuator 56 selectively coupled to the main hydraulic pump via a main control valve 54. The system also comprises a controller 80 configured to: receive one or more input signals 82A, 82B from the one or more pilot pressure sensors; and send one or more electric output signals 84A, 84B to actuate the main control valve depending on the one or more input signals received from the one or more pilot pressure sensors.

A working machine includes a body, a ground engaging propulsion structure supporting the body, and a working arm mounted to the body. The machine also includes a control system and a collision avoidance system. The collision avoidance system has a camera mounted on the body of the working machine configured to monitor an area in its field of view and to generate an output signal to the control system in response to a detected animate object in said field of view. The control system includes a processor configured to execute a machine learning algorithm trained to determine whether the detected animate object is an animate object to determine whether an animate object is within the field of view of the at least one camera from the camera output signal. The system provides an output to alert an operator of the working machine if it is determined that an animate object has been detected in the field of view of the at least one camera.

The present disclosure provides a method of manufacturing a textured building product. The method comprises: a) creating a heightmap of a textured surface (14); b) using the heightmap to create a 3D model of a textured embosser (10) comprising the textured surface; c) using additive manufacturing to produce a textured embosser based on the 3D model; and d) imparting the textured surface of the textured embosser onto a surface of a building material (30) to produce a textured building product (34).

Aspects of the present invention relate to a working vehicle steering system 100. The working vehicle steering system comprises: one or more steerable wheels 14; a steering actuation system 120 configured to move the one or more steerable wheels between a range of steering angles; a steering angle sensor 108; and a controller 136. The controller is configured to: receive a steering angle signal 110 from the steering angle sensor; determine whether a steering angle of the one or more steerable wheels is within a predetermined steering angle range; and when it is determined that the steering angle is within the predetermined steering angle range, output a control signal 138 to direct the steering actuation system to automatically move the one or more steerable wheels towards a central steering angle position.
