摘要:
The invention relates to a device for the wireless transmission of data and energy between an element to be mounted on or in a vehicle body, especially a vehicle sliding door (2), a vehicle seat or a comparable additional unit, and a vehicle body (1). The basic design of the inventive device comprises an electric power source (18), control electronics (17, 17′) mounted in the vehicle body and at least one pertaining coil (20) also mounted in the vehicle body. The device further comprises control electronics (11) mounted in the element and at least one pertaining coil (19) also mounted in the element. Both coils (19, 20) are inductively coupled via a common transmitting/receiving path to transmit data and energy. According to the invention, the coil (19) mounted in the element is enclosed by the coil (20) mounted in the vehicle body and can be displaced in a longitudinal direction within the coil (20) mounted in the vehicle body or vice versa.

Method for wire-free transmission of data packets between network nodes in a control network, wherein the data packets each have a preamble for synchronization consisting of a predetermined number of preamble symbols, and wherein during a first operating mode, each preamble-subsymbol of a preamble symbol in the preamble is coded by the phase angle of a transmitted single signal pulse, during a second operating mode to increase the signal recognition performance, for the preamble which is transmitted in the data packet, a signal pulse sequence for coding the preamble-subsymbol is transmitted instead of a single signal pulse, where the single signal pulse within the signal pulse sequence is transmitted repeatedly.

A method for associating time slots with links between network nodes of a wireless interconnected network, the data in the network being transmittable from a source node to a destination node on a time slot basis by association via hops or corresponding hop levels, wherein a main path having one network node per hop level and the corresponding links between the network nodes of adjacent hop levels is set from the source node to the destination node, and alternative network nodes having corresponding alternative links, which can be used in place of the main path for data transmission, are also set.

A drive arrangement for a motor vehicle door or hatch which can be moved by a motor with a planet gear and a brake device with a brake. The brake device has a brake drive which is separate from the drive which drives the drive shaft and the brake is able to be moved at least from one of two positions into the other of the two positions by the brake drive. The brake can be an arc-shaped clip pivotally supported by a pivot axle with an inner periphery which is matched to an outer periphery of an element of the planet gear. The brake can be combined with the brake drive as an eddy current brake or can be operated by a further gearing or use of a permanent magnet with which an electromagnet is able to interact.
摘要:
A method of associating time slots with a transmission path in a wireless interconnected network made of a plurality of network nodes such that the transmission path extends between a source node and a destination node and comprises a plurality of sequential links between adjacent network nodes, data being transmitted in the network on a time slot basis by the association of the time slots to be used with the links of the transmission path, wherein a quality value is determinable for each link within an association sequence of time slots describing an end-to-end data transmission from the source node to the destination node along the transmission path, where the value represents the reliability of the data transfer. An overall quality value for the association sequence can further be determined as a function of the quality values of each of the links.

Opening and closing system for motor vehicle sliding door, which can be displaced along guide rails between an open position and a closed position, with a brake device for braking the sliding door. The brake device is designed in such that it is activated automatically during displacement of the sliding door when a collision state is indicated or signaled or exists during opening and/or when a jamming state is indicated or signaled or exists during closing (pre-crash situation). The opening and closing system can thus react without any time delay to a jamming or collision state and can rapidly brake the displacement of the relatively heavy sliding door. At the same time or with a time offset, a drive motor for the motorized movement of the sliding door can be braked and/or reversed. The opening and closing system can be used both for manually operated and automatic sliding doors.

A drive arrangement that is an economical structure that makes optimum use of existing installation space is achieved by a drive arrangement, for actuating the hatch of a motor vehicle that is coupled to the body of the motor vehicle to pivot around a hatch axis opening and closing a hatch opening of the body, of the type having a drive motor and a gearing connected on an output side of the drive motor for producing drive motions and movement of the hatch between an open position and a closed position, the gearing having an actuating element which is pivotable around axis of the actuating element and having a push rod which is coupled to the actuating element with an offset respect to the axis of the actuating element, in which the actuating element axis is arranged essentially perpendicular to the hatch axis.
摘要:
A bus device that has recently been connected to a bus system is first addressable at a pre-set address. A bus master transmits a new address and an identification to the bus device. The bus device compares the transmitted identification with an identification that has been stored in the bus device and assumes the transmitted new address, if the transmitted identification corresponds with the identification that has been stored in the bus device. The bus device is then addressable at the new address.

The invention relates to a method for establishing an end-to-end communication between two networks, wherein: a message is received from one first network, this message having a first header and an application-data part; data of said first header is coded into a second header within the application data part, with the aid of a first coding scheme, so as to produce a modified application data part; said modified application data part is coded with the aid of a second coding scheme so as to produce a coded message; and this coded message is transmitted to a second network.
