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.

Abstract: A contact arrangement for interrogating the data and counting values of a wheel revolution counter. The contact arrangement is accessible from the outside at an otherwise hermetically closed housing. The wheel revolution counter is conventionally fastened at a wheel hub of a vehicle in a cantilevering manner. The contact arrangement comprises a contact plate which is fastened axially in the front housing wall together with an insulating bush having a collar serving as a spacer. An adhesive layer fills the gap between the contact plate and the housing. This adhesive layer extends out on the outer surface of the housing and separates the outer surface of the contact plate and the end face of the housing with an insulating layer covering a large surface area.

Abstract: The proposed plug-in connection provides that the wheel revolution counter itself or its free end, respectively, are constructed as a plug-in connection part with exposed contact paths, the wheel revolution counter being fastened e.g. at a rim of a vehicle wheel, and the counterpart of the plug-in connection provided e.g. in a hand-held device serving for the data take-over. Reciprocally acting catch members and the contacts which latter are assigned to one another, are constructed in such a way that it is possible to connect the wheel revolution counter and data take-over device regardless of position and in such a way that a reciprocal rotation is enabled which serves for making contact.

Abstract: A control arrangement for a display unit, for use in a motor vehicle for digital presentation of vehicle operational data, is located within a housing having a display face. A multi-way push button is accessible on the display face and extends into the housing for operating at least two switches. The push button is pivotally mounted for operating different ones of the switches when specific operational data is desired.

Abstract: A vehicle information apparatus for recording, computation and display of data ascertainable from the driving performance of a motor vehicle. The apparatus includes a transmitter module for providing data concerning a trip, a central unit with internal program and data memories and a display device. The vehicle information apparatus is coupled with the operating mechanism of a radio cassette set for playback of data information stored on an audio data carrier. The transmitted data are separated in a signal input and output stage of the apparatus, stored and displayed. The audio data carrier is repeatedly loaded with topical information and serves particularly for the distribution of instructions prior to the start of a driver's shift in a taxi or transportation vehicle fleet.

Abstract: A device for transmission and storage of energy into a mobile data carrier designed in a card-shaped manner, which is insertable into a flute-shaped transmission unit. The transmission unit is designed as a capacitively acting coupling station for energy and information and consists of two flat electrodes spaced from each other, which are embedded into material layers having high dielectric constants. The mobile data carrier also consists of two flat electrodes, arranged in parallel planes with respect to each other, which are coated externally with dielectric material and have therebetween a printed circuit board carrying electronic circuit elements. The mobile data carrier is particularly suitable for application areas involving data acquisition in a motor vehicle branch or in industrial utilization involving rough handling.

Abstract: An arrangement is described for the selection of a tariff level "n" by repeated actuation of a key T1 or T2, which can be actuated in series, whereby the desired tariff level is adjustable by forward switching or reverse switching. Each selected tariff level is displayed immediately after detecting the key actuation by an allocation sentinel (27) in a display (10), and the start of a waiting time, which can be preset, can be triggered in each tariff selection. After the expiration of the waiting time, a parameter assigned to the last selected tariff level appears in the fare display field (26) and, accordingly, signals the acceptance of the last selected tariff level including the activation of all of the rest of the parameters assignable to the selected tariff level. It is possible, thereby, to select a tariff level by skipping over undesired tariff levels without the fare display being changed during the selection process.

Abstract: A method and arrangement for providing a continuous visual check on the operation of a standard liquid crystal display by superimposing a checking signal upon the operating signals applied to the individual segment and back electrodes of the LCD through individual impedance paths substantially higher than the individual impedance paths carrying the operating signal to the segment and back electrodes so that the operating signal overrides the checking signal under normal circumstances but the checking signal overrides the operating signal when the latter is interrupted due to a fault. The checking signal causes the segment electrode or back electrode whose signal is impaired to blink at a visually perceptible rate. Preferably, the frequency of the checking signal is in the order of 0.5 Hz to 2.0 Hz.

Abstract: The invention relates to a remote control device of a gear-box for motor vehicles with incorporated compressed-air system. A gear-shifting gate with servo-pneumatic control provided at the gear-box for setting the gears comprises substantially two working cylinders controlled by servo-valves whose travels are signalled via position indicator switches. A gearshift lever console in the driver's cabin transmits the shifting commands via position indicator switches to electronic control means which in turn control the gear-shifting gate at the gear-box. For feeding back to the gearshift lever the shifting states prevailing at the gear-box, a working cylinder is provided in the gearshift lever console which acts directly on the gearshift lever via a mechanical link.

Abstract: A circuit arrangement for the permanent protection of data in volatile write-read memories (RAM) such as the type used for the storage of tariff data and variable control counter data in a taximeter. The inventive circuit arrangement provides a signal line between the microcomputer system and a volatile write-read memory (RAM) via a control circuit. By means of this arrangement, in the sealed state of the taximeter, a permanently effective suppression of write instructions can be set. Thus, the data stored there can no longer be affected by any interference signals from the microcomputer system. The supply of operating voltage of the RAM is secured by means of a circuit which includes a buffer battery and a buffer capacitor.

Abstract: An arrangement for the control of the quantity of the functions to be called in an electronic taximeter. In order to be able to adapt the device to the most multipurpose of demands, a greater or fewer number of recesses with keys A1 to A8 or with corresponding fill-in pieces can be provided in a key strip in a taximeter housing. A switch K1 through K8 is assigned to each key A1 through A8; the key information is supplied to the electronics and releases different key interrogation programs according to the number of keys present. With a smaller quantity of keys, several functions are assigned to the keys partially; with a larger quantity of keys, each key preferably releases only one function.

Abstract: A taximeter assembly including an electronic calculating module with data memory, an operating keyboard, as well as a data indicating device, consists of two flat housing panels which are joined by detent devices and which are secured together by a lead-sealable screw connection. An electronic taximeter circuit wired on a single printed circuit board is installed between the housing panels and feed-in of all electrical transmitter lines and supply lines is effected, as desired, from the rear or from below, wherein the latter are guided directly to connectors on the printed circuit board. The rear wall of the rear housing panel is constructed, at the same time, as a mounting plate for installation in a vehicle. A compact, extremely flat taximeter device having its circuitry in a single printed circuit board system enables arrangement of the device in an optimal installation position within or on the outside of the dashboard of a vehicle.

Abstract: In the taximeter disclosed, a microprocessor responds to a first set of pulses representing time and a second set of pulses representing distance and receives data representing a tariff from a constant store. The microprocessor calculates fares and advances the fares continuously on the basis of new calculations, while entering the results in a display for the driver and passenger. The constant store is in the form of a non-volatile memory for receiving programming data from an external source through a connector.
