Abstract: A device for detecting a measured value includes a measuring transducer and a channel sensor, which is implemented as an essentially cylindrical tube having a first end and a second end and may be mounted in a wall when the measuring transducer is situated on the channel sensor. A detachable fastening device is included for fastening the measuring transducer to the channel sensor and may be disposed between the measuring transducer and the channel sensor. The channel sensor may be connected to the measuring transducer via a cable.

Abstract: In order to transfer energy in a contactless and inductive manner, a primary circuit comprises two parallel lines (9) along which a vehicle comprising a secondary circuit travels. The two lines forming the primary circuit are arranged in the ground in such a way as to ensure the observation of a given distance in relation to the vehicle. U-shaped holding elements (4) are provided, the centre limb (5) thereof comprising two curved holding limbs (8) between which a line (9) is secured. The outer sides of the holding limbs (6) of the U-shaped holding element (4) are provided with projections extending in the longitudinal direction of the holding elements (4). Said holding elements (4) are placed in a rectangular recess (3) in the ground in a vertically adjustable manner by means of said projections.

Abstract: For automatic CAN address allocation each bus subscriber still to be allocated an address, generates a random value for a provisional address on system power up. On receiving a request to commence address allocation each bus subscriber writes a telegram claiming the provisional address into the CAN send buffer. If a bus subscriber receives a telegram claiming an address which agrees with its own provisional address, a new random value is generated for a provisional address and a telegram claiming this provisional address is written into the CAN send buffer. If the telegram claiming the provisional address is sent before a telegram claiming the same provisional address is received, the provisional address is deposited in the writeable non-volatile memory as the final address.
