A utility vehicle to remove a matter from a surface may include an articulated collector attached to a front section of the utility vehicle. The articulated collector is movable. The articulated collector is also configured to remove the matter from the surface. A matter container is also connected to the utility vehicle. The articulated container is also connected to the matter container. The matter container is configured to receive and hold the matter. Furthermore, an articulated depositor is connected to the matter container. The articulated depositor is configured to deposit the matter to a disposal site.

A clay court drying apparatus including a vacuum attachment, wherein the vacuum attachment may include a vacuum head; an intake portion formed in a first region of the vacuum head; and an outlet portion formed in a second region of the vacuum head. The clay court drying apparatus may further include a filter mechanism disposed at the intake portion of the vacuum head.

The invention relates to a safety method for an emergency vehicle, the emergency vehicle being configured to be autonomously operated and comprising: an energy storage unit; sensor devices arranged to monitor the surroundings and the vehicle; a water pump; at least one connection unit for an external water source and/or a water hose; conduits arranged in fluid communication with the water pump and/or the at least one connection unit; a valve arrangement arranged in fluid communication with the water pump, the at least one connection unit and the conduits, the method comprising: receiving a command from a control center to operate the vehicle to a location associated with an emergency situation; operating the vehicle to the location; and controlling the vehicle to perform a safety function to alleviate the emergency situation.

The invention relates to a vacuum installation for industrial application, the installation comprising a first vessel having a first gas inlet for allowing a gaseous substance into the first vessel and a first outlet for depletion of a material, a second vessel having a second inlet for aspirating a quantity of material and a second gas outlet for depletion of the gaseous substance, wherein the gaseous substance comprises a vapour generated from the material, a storage chamber for storing the quantity of material, the storage chamber having a third inlet, wherein at least the first vessel communicates with an interior of the storage chamber via the first outlet and the third inlet; and a vacuum pump located in between the first vessel and the second vessel, and operated to lower the pressure in the second vessel, thereby allowing the material to be sucked into the second vessel via the second liquid inlet to an equilibrium level between the material and the gaseous substance, the vacuum pump being further operated to transport the gaseous substance to the first vessel to raise the pressure in the first vessel, thereby forcing the material in the first vessel into the storage chamber.

A service mode selection system for a service vehicle is provided for simplifying a control for setting the vehicle in a desired service mode. The system includes a control system for receiving an operator's selection of service mode via a service mode selection device and controlling vehicle components to automatically set the vehicle in a selected service mode. The service mode selection device can be arranged in a cab of the vehicle and allows the operator to conveniently select a desired service mode, thereby achieving a work-ready machine with as few operator inputs as possible.

Disclosed is a drying device, which comprises: (a) one or more fabric panels of sufficient dimension to be dragged across a surface, optionally an outdoor surface; and (b) a handle attached to the one or more fabric panels, In some embodiments, the drying device comprises: (a) two or more fabric panels of sufficient dimension to be dragged across a surface, optionally an outdoor surface; (b) a handle attached to the two or more fabric panels; and (c) a scraper attached to the handle, wherein the scraper is adapted to engage a surface to be dried when the drying device is in use. Methods and systems for a drying a surface are also disclosed.

The present invention relates to a de-icing and/or anti-icing liquid recovery system for recovering de-icing and/or anti-icing liquids from airport apron/deicing platform surfaces, the system comprising: a deicing-liquid recovery unit; a pump; and a collection tank, where the deicing/anti-icing liquid recovery unit comprises a rotatable brush; a baffle; and a sorting tray fluidly connectable to said collection tank via pump, where the rotatable cylindrical brush is arranged to sweep a apron/deicing platform surface such that materials on the apron/deicing platform surface is forced over the baffle and into the sorting tray, wherein said filter is configured to separate liquids and solid phase materials from said swept-up material, and where liquids collected in the sorting tray can be pumped to the collection tank via said pump. The invention also relates to a de-icing and/or anti-icing liquid recovery and a method for de-icing and/or anti-icing liquid recovery.
