Abstract: In a device for wireless transmission of electrical signals between the steering wheel of a vehicle and the chassis of the vehicle, a first transmission module, which includes a microcontroller and a transmitter for electromagnetic waves, is provided on the steering wheel. The microcontroller is designed to condition and convert electrical signals of operator control elements, arranged on the steering wheel, into signals which are suitable for the transmitter module. A second transmission module which includes a receiver and a microcontroller is arranged on a fixed region or chassis of the vehicle. The latter microcontroller is designed to convert signals which are received in the receiver into switching and/or control signals for electrical devices of the vehicle.

Abstract: A lithium ion battery (200) has at least two carbon foam electrodes (54, 56). Each of the electrodes (54, 56) is fitted with a plate (60, 62 respectively) formed from an electrically conductive material. The plate (60, 62) has an underside which is formed so as to be attached to one end of the carbon foam electrode (54, 56). The plate (60, 62) may be fixed to the electrode by crimping or a similar deforming process or may be fitted thereto by an electrically conductive adhesive.

Abstract: There is disclosed herein a utility/camper multiple purpose shell integrated with a pick-up truck frame and cab. The shell is adaptable (1) to being fully opened at the rear, (2) to having the roof thereof pivotally raised to permit standing room for a user, (3) to having flexible walls attached to the raised roof suitable for camping therein, and (4) to having the roof thereof lifted off of the front and side walls. The shell components are formed of light weight materials and bonded together.
