A mobile portable tool, such as a spreading device, cutting device or combined device with cutting and spreading function includes a housing. An electric motor is located in the housing. The tool includes a rechargeable battery or a connection to an external electrical energy source. The tool is a mechanically or hydraulically driven and has a displaceable piston rod spreading and/or cutting and/or lifting and/or pressing work. An electronic open-loop and closed-loop control unit controls the electric motor and includes a printed circuit board and control cables with a connector for transporting control signals. For under water operation while still having a simple design, the electric motor is a brushless direct-current motor. The electronic components of the printed circuit board are enclosed by a potting compound to prevent water entering, and the connector of the control cable is protected against the ingress of water.

A vehicle window glass shear system and method for causing shearing breakage of vehicle window glass under emergency conditions by a concealed and easily operated system, having a concealed handle unit having a handle, a handle-unit bracket, and a handle-unit cable brace, having a concealed shear unit mounted on the bottom edge of the vehicle window with a shear-unit bracket, window-clamping plate, and fasteners, a shear bolt with a piercing point, a shear drive wheel, and a shear-unit cable brace, and having a cable within a cable sleeve transferring the activation force from the handle unit to the shear unit, driving the shear bolt toward the vehicle window and driving the piercing point into the vehicle window causing shearing breakage of the window glass.

A multi-purpose tool and a method for use thereof, where the multi-purpose tool includes a first component having a first shaft and at least one first tool affixed thereto and a second component comprising a second shaft having at least one second tool affixed thereto, the second shaft being substantially hollow and capable of slidably receiving the first shaft. The multi-purpose tool further includes a quick-securing mechanism disposed along the length of the second shaft including a dial that is rotatable relative to the second shaft and having a threaded portion affixed to the dial. The quick-securing mechanism is configured to move a pin into an extended position when the dial is rotated in a first direction, and to move the pin into a retracted position when the dial is rotated in a second direction. The pin interacts with one of at least two holes in the first shaft to secure the first shaft in either a compact or extended configuration relative to the second shaft.

A robot for detecting and saving a life, includes: a body part including a plurality of unit joints; a head part which is provided at the front of the body part in the direction in which the body part moves forward, and which has a gripper capable of picking up an object by a plurality of tongs parts that are folded and unfolded; and an extension part capable of extending forward from the head part so as to enter a small space that is difficult for the body part to enter.

The invention provides door and window sensors, which can be incorporated into building pressurisation and depressurisation systems, for use in protecting a building's escape routes against smoke ingress during a fire.

A tool includes at least one motor, and a pump connected to the motor, a work cylinder in fluid connection with the pump and an actuable tool component connected to the work cylinder. The pump and the motor are arranged directly adjacent on a common singular motor and pump shaft, without any intervening coupling, transmission or the like. An assembly of a motor and a pump on a common shaft.

An impact tool includes a core and a plurality of projections. The core is formed of a first material that has a first specific gravity and each projection is formed of a second material that has a second specific gravity. The plurality of projections is configured on the core such that at least two projections intersect a first hypothetical plane disposed on the first side of the core and at least two projections intersect a second hypothetical plane disposed on the second side of the core and that is opposably facing the first side. Each of the first and second hypothetical planes is disposed a distance from the central lengthwise axis of the core that is greater than the radius of the core and less than the sum of the radius of the core and the length of a projection.

A sun visor assembly for a vehicle that includes a mount configured to be connected to the vehicle. A guide rod having a first portion that includes a head and a second portion with a terminal end is operably coupled to the mount via the head. An impact point is at the terminal end of the second portion. The guide rod and the impact point are configured for use as a window breaker tool in a disassembled position. A visor is operably coupled to the guide rod in an assembled position and is rotatable about the guide rod from a first position to a second position. The visor includes a channel defined within the visor that is configured to receive the guide rod.
