Abstract: A method for adjusting the position of a power lift of an agricultural utility vehicle includes storing one or more target positions in a control device, moving the control member rotationally relative to and translationally along a longitudinal axis, and adjusting the one or more target positions of the power lift within a position range defined by a lower limit position and an upper limit position by a variable movement of the control member.

Abstract: A system for interrogating sensors in a fiber optical sensor network includes groups of sensors. The sensors in one group operate at different wavelengths, and the sensors of other groups may have overlapping wavelengths. A light source generates a broadband light signal, input and output means for guides the broadband light to the fiber optical sensor network for illuminating the sensors and for coupling the light signal coming from the sensors of the fiber optical sensor network to the detection system, and a detection system detects the received light signal, during a detection integration time. The system is arranged for selecting pre-dominantly the received light coming from the different sensors of a selected group of sensors using a code-division multiplexing technique and simultaneously detecting sensors of the selected group of sensors using a wavelength-division multiplexing technique.

Abstract: A velocity control mechanism is operable to control a vehicle at a maximum forward velocity setting and a maximum rearward velocity setting. The velocity control mechanism includes a processor configured to receive a first signal from an actuator selectively positionable in a velocity control mode in which the vehicle operates at a maximum limited forward velocity less than the maximum forward velocity setting and a maximum limited rearward velocity less than the maximum rearward velocity setting. The first signal represents a desired vehicle forward velocity. The processor also configured to control a velocity of the vehicle in the forward direction based on the first signal and receive a second signal from the actuator. The second signal represents a desired vehicle rearward velocity. The processor further configured to control a velocity of the vehicle in the rearward direction based on the second signal.

Abstract: A velocity control mechanism for a vehicle operable to move in a forward direction and a rearward direction. The velocity control mechanism includes an acceleration control mode operable to accelerate the vehicle in one of the forward direction and the rearward direction, a velocity control mode operable to control a velocity of the vehicle in one of the forward and the rearward direction, and an intermediate control mode positioned between the acceleration control mode and the velocity control mode. An actuator is moveable between the acceleration control mode and the velocity control mode and is biased into the intermediate control mode.

Abstract: A digital voting method for a computer system having a voting booth system, a validator system, and a bulletin board system, where the validator system has access to certificates of authorized voters, includes generating using the voting booth system, a vote; blinding/signing the vote using a signature of the voter; sending the blinded/signed vote to the validator; verifying the voter's signature; checking that the voter is authorized, and checking whether the voter has received a validator signature, wherein if not the validator signs the blinded vote; sending the validator signature back to the voting booth system; unblinding the signature; verifying the validator signature, and if correct encrypting the vote along with the validator signature using a tallier's public key; encrypting the vote using a public key to provide a dual-encrypted vote displayable to the voter; transferring the dual-encrypted vote to the bulletin board; and if the voter is authorized publishing the dual-encrypted vote.

Abstract: The invention concerns a device for operating a vehicle provided, in particular, in the form of a farming or industrial utility vehicle. The device comprises a grip (12) that can be rigidly mounted on a console of the vehicle. The grip (12) is designed in such a manner that enables it to be at least partially grasped by an operator's hand or is suited for being at least partially reached into by an operator's hand. The grip (12) comprises operational controls (18, 20, 22), with which at leas one function of the vehicle and/or one function of an implement that can be optionally adapted to the vehicle can be controlled. The aim of the invention is to resolve ergonometric problems during operation. To this end, a display unit (24) assigned to the grip (12) is provided that can be mounted in a manner that permits it to be displaced relative to the grip (12).
