20100272384 | FORCE-MOMENT SENSOR - A force-moment sensor is provided for measuring at least one force and/or moment, which comprises a first part, a second part and an optical fibre arranged therebetween, said optical fibre comprising in at least one section a component for detecting deformations and/or stresses of the fibre transversely to its longitudinal axis. The present invention further relates to a method for measuring forces and/or moments. Thus, a fibre is provided which comprises at least one component for detecting deformations and/or stresses of the fibre transversely to a longitudinal axis of the fibre and into which light is introduced. According to this method, a force and/or moment acts on the fibre, wherein at least one component of the force and/or moment acts perpendicularly to the longitudinal axis of the fibre. The light reflected in the fibre is then detected and the detected spectrum analysed. | 10-28-2010 |

20100252114 | CONTROLLABLE VALVE FOR AN AIRCRAFT - A controllable valve is provided for a low-flammability fluid within an aircraft with at least one magnetic coil which, upon brief electrical excitation, moves a structural element provided therein from a first position to a second position in which the structural element is held by a permanent magnet after completion of the electrical excitation of the magnetic coil. | 10-07-2010 |
20140140864 | HYDRAULIC MOTOR-PUMP-ARRANGEMENT AND HYDRAULIC SYSTEM FOR A VEHICLE - An arrangement for selectively making available hydraulic power in separate hydraulic circuits comprises two displacement machines, two free-wheels and a drive unit that is preferably arranged between the displacement machines. The free-wheels block in opposite directions and are coupled to the displacement machines. Consequently, the first displacement machine is driven in a first rotating direction of the drive unit while the second displacement machine is only driven in a second, opposite rotating direction of the drive unit. This makes it possible to realize an intermittent operation for selectively making available additional hydraulic power in separate hydraulic subsystems by choosing the rotating direction accordingly. This arrangement can reduce the weight and the complexity of a hydraulic system. | 05-22-2014 |
20140299806 | SHUT-OFF VALVE - A shut-off valve is provided. The shut-off valve includes a valve body having an inlet and an outlet, and a shut-off element, which is arranged in the valve body and through which a shut-off element through-channel is formed, which ends at its two ends in two mutually spaced first openings in an outer surface of the shut-off element. The shut-off element is movable between a shut-off position, in which the shut-off element blocks a fluid flow, and a flow position, in which the shut-off element allows a fluid flow between the inlet and the outlet of the valve body through the shut-off element through-channel. The shut-off element includes a first pressure-compensation channel opening with an inner end into the shut-off element through-channel, and the valve body includes a second pressure-compensation channel. | 10-09-2014 |

20080305922 | HYBRID DRIVE SYSTEM FOR A VEHICLE AND METHOD OF OPERATING THE HYBRID DRIVE SYSTEM - A hybrid drive system is provided for a vehicle. The hybrid drive system includes, but is not limited to a traction battery, an internal combustion engine and an electric drive. The internal combustion engine and the electric drive provide propulsion drives and are configured to be operatively and selectively coupled to a transmission. The internal combustion engine includes, but is not limited to a heater for pre-heating a selected portion of the internal combustion engine. The traction battery is coupled to the heater and configured so as to be able to provide electric power to the heater whilst the propulsion drives are switched off. | 12-11-2008 |

20120110413 | METHOD FOR CODING AND DECODING DIGITAL DATA, PARTICULARLY DATA PROCESSED IN A MICROPROCESSOR UNIT - The invention relates to a method for encoding digital data, in particular of data processed in a microprocessor unit. In the method according to the invention for a respective data word (A, B, C) of a series of data words to be encoded subsequently a parity code (P(A), P(B), P(C)) is computed on the basis of the data of the respective data word (A, B, C). Further the respective data word (A, B, C) is altered with the aid of the data word (A, B, C) preceding it in the series, wherein the altered data word (Aa, Ba, Ca) and the parity code (P(A), P(B), P(C)) represent the encoded data word (Ac, Bc, Cc) and the encoded data word (Ac, Bc, Cc) can be decoded with the aid of the data word (A, B, C) preceding it in the series. | 05-03-2012 |
