| 20080206603 | Arrangement Having a Battery | 08-28-2008 |
| 20080219441 | Arrangement Comprising an Integrated Circuit - An integrated circuit ( | 09-11-2008 |
| 20100100749 | Single-Chip Computer and Tachograph - A single-chip computer includes at least one first processor core and at least one second processor core constructed on a common chip. The at least one first and the at least one second processor cores are interconnected via a processor interface. Data can be read via a separate or common memory interface from a separate or common data memory respectively and/or stored in said data memory. The single-chip computer includes an encryption and decryption unit which is assigned to the at least one processor core and which is constructed and functionally arranged between the at least one second processor core and the memory interface in such a way that the data which can be exchanged between the at least one second processor core and the data memory can be encrypted and decrypted by the encryption and decryption unit. | 04-22-2010 |
| 20100209747 | Energy Storage Unit - An energy storage unit, particularly for a motor vehicle, has an application unit that is configured to detect and/or process predetermined operating parameters of the energy storage unit. The energy storage unit further includes a safety unit that is configured to cryptologically process the detected and/or processed operating parameters. The energy storage unit also includes a communication interface for making the cryptologically processed operating parameters available. | 08-19-2010 |
| 20100250053 | Tachograph, Toll Onboard Unit, Display Instrument, and System - A tachograph and a toll onboard unit as communication partners, which each have a data interface for a data communication via a vehicle data bus to which the communication partners are coupled. The tachograph and/or the toll onboard unit are implemented as a transmitter of data to ascertain a cryptographic check value as a function of user data, which are to be transmitted to the communication partner, and to transmit the cryptographic check value in addition to the user data to the communication partner. The toll onboard unit or the tachograph, respectively, as a receiver of data, is implemented to receive user data and the cryptographic check value associated with the user data from the communication partner and to check the received user data for corruption as a function of the received cryptographic check value. | 09-30-2010 |
| 20100284235 | Method and Control Unit for Operating a Volatile Memory, Circuit Arrangement, and Trip Recorder - A method for operating a volatile memory supplied with a supply signal arranged either as a first supply signal of a first supply signal source or a second supply signal of a second supply signal source. If an available first supply signal is present it is used otherwise the second supply signal is used. The supply signal is supplied, based on a switch position of a switching element to the volatile memory. During a detected interrupted first supply signal, the switch position of the switching element is for a predetermined period of time such that the supply signal is supplied to the volatile memory. After expiry of the predetermined period of time, the switch position of the switching element is predetermined such that the volatile memory is decoupled electrically from the supply signal. | 11-11-2010 |
| 20110137490 | MOBILE INTERFACE AND SYSTEM FOR CONTROLLING VEHICLE FUNCTIONS - A mobile interface for controlling a plurality of vehicle functions in a motor vehicle using a controller connected to the vehicle, having a wireless data interchange with a controller, an input apparatus, and an energy store. By virtue of the wireless data interchange being connected to a data processing unit integrated in the mobile interface and which is designed to apply at least one cryptological method, a greater scope of functions becomes possible that can also include control of safety-relevant vehicle functions. | 06-09-2011 |
| 20120245757 | Vehicle Data Recording Device - A vehicle data recording device including a vehicle data recording unit which has a housing, a data memory arranged outside the housing, and a unit interface with a connection for the data memory is provided in an outer wall of the housing. The data memory is connected to the unit interface by a connecting cable. To ensure not only that the data memory is reliably arranged in the vehicle data recording device but also that the data memory can be easily removed from the device, the housing has, on a housing outer side, a mount that detachably supports the data memory. | 09-27-2012 |
