Abstract: In the proposed tachograph, a thermal print head (29) and a feed roller (35) are spatially separated from one another. A starting section (38) of the printing material (32), which section projects by a suitable length, is automatically clamped between the thermal print head (29) and the feed roller (35) when the drawer (28) closes. One of the closure gaps of the drawer (28) is designed as an output slot (24) for the printed documents produced.

Abstract: A data-transmission device has a pulse generator (1) and a monitoring unit (20) for use in a vehicle. A signal generated by the sensor (2) is transmitted from the pulse generator (1) to the monitoring unit (20) by a signal line (9) and also, when requested by the monitoring unit, is transmitted in encrypted form along a data line (19). The signal generated by the pulse generator (1) is first stored in an intermediate store. Before transmission, the contents of this store are encrypted. On arrival in the monitoring unit, the encrypted signal is compared with the signal previously transmitted in the usual way and recorded there. This is a security check which reveals any manipulations which have been made during transmission.

Abstract: A driving data recording device for a motor vehicle for collecting at least one of time- and speed-dependent data and including, housing having an element for securing the housing to a housing shell of a motor vehicle drive gear, a control module for processing collected data and located in the housing, and a memory located in the housing and cooperating with the control module.

Abstract: A device for short-distance recording for motor vehicles is disclosed for the evaluation of an accident or near-accident driving situation. A storage arrangement is provided in which speed measurements are simultaneously written into at least two parallel storage branches. A plurality of time-limited storage areas are defined in each storage branch. Each storage area has a storage portion which can be operated as a ring storage and a storage portion arranged subsequent to the latter which can be operated as a linear storage. The speed values, which are written into the ring storage in a continuous manner during the course of normal driving, are permanently stored in one storage branch when the criterion v equal to 0 km/hr occurs, and in the other storage branch when the criterion a greater than a deceleration threshold value occurs.

Abstract: An apparatus is described for increasing a fare to a rounded-off amount, in which the fare is determined by an electronic taximeter and prior to the preparation of a voucher in an assigned voucher printout mechanism the amount payable is rounded-off by an increase of the fare amount manually preselectable in predetermined steps, based on an actuation of operating keys. A stepwise or discretely adjustable rounding-off is selectable for printout in the voucher printer in such a way that the voucher shows the sum, formed from the fare+surcharge+additional amount selected by the passenger.
