  • Patent number: 8417036
    Abstract: Presented is a method for selecting a label from a multiplicity of labels stored in a memory element. The method includes inputting a handwritten character into a handwritten input apparatus, associating an alphanumeric character with the handwritten input character using a character recognition apparatus, adding the associated alphanumeric character to an already input character string to produce an extended character string, comparing the extended character string with the labels stored in the memory element, and selecting one or more of the stored labels using the comparison. The alphanumeric character is selected from a dynamically alterable character set which contains only characters which, in addition to the already input character string, produce an extended character string, which is an initial component of at least one of the stored labels. Also presented is a motor vehicle navigation system in which address database entries are selected by the above described method.

  • Patent number: 7932628
    Abstract: A terminal state of a terminal 15 of a vehicle is enabled to be maintained for a minimum period of time even after a drop in the voltage supply. At the same time other loads are to have no effect on the holding time. A control device for controls access to a vehicle and has a voltage source, a voltage supply terminal to which a supply voltage can be applied, and a holding circuit to which the voltage source and the voltage supply terminal are connected in a common circuit point for the purpose of holding an On state for as long as the voltage at the voltage source does not fall below a predetermined value. A switching element that is connected into the circuit between the voltage supply terminal and the common circuit point serves to separate the common circuit point from the supply voltage. The holding time is thus decoupled from the VCC currents drawn by other loads.

  • Patent number: 7872568
    Abstract: A method for stimulating wheel electronics systems of single tires of at least one tire group in a motor vehicle. The wheel electronics systems are stimulated with a low frequency trigger signal, as follows: a trigger signal is emitted from an LF trigger to the wheel electronics systems of the relevant tire group at a variably adjustable first transmission field strength. Radio frequency signals are transmitted from those wheel-side wheel electronics systems, at which a sufficiently high transmission field strength of the trigger signal has arrived containing an item of trigger information, to a vehicle-side receiving unit. A determination is made of the number of RF signals received by the vehicle-side receiving unit, each containing one item of trigger information.

  • Patent number: 7868259
    Abstract: A device has a housing (1) with a frame element (8) which is arranged within the housing (1). The frame element (8) accommodates at least one component and has at least one bending arm (12). The bending arm (12) is designed such that a contact region (36) of the bending arm (12) bears with prestress against a contact region (38) of a wall (34) of the housing (1) in a mounted state within the housing (1). The bending arm (12) is cohesively connected to the housing (1) by means of transmission laser welding by supplying a laser beam (46) of prespecified wavelength to the device in such a way that the laser beam is transmitted through the housing (1) to the contact region (36) of the bending arm (12).

  • Patent number: 7864529
    Abstract: To improve coolant sealing or reduce the risks in the event of leakage for an electronic unit, e.g. an engine control unit, containing electric and/or electronic components which are disposed on an upper side of a thermally conductive electronic base plate and thermally coupled to the base plate, the base plate in turn being thermally coupled to a coolant passage, there is provided a particular configuration and arrangement of the components delimiting a coolant passage. Advantageously, the underside of the base plate can come into direct contact with a coolant (“direct cooling”). By making a ridge running in an annularly closed manner and being formed in one-piece with the base plate, coolant escaping from the coolant passage is prevented from passing directly to the underside of the base plate. Accordingly, the coolant passage may be sealed by a “double sealing arrangement” on the underside of the base plate.
