Abstract:
In a device for wireless transmission of electrical signals between the steering wheel of a vehicle and the chassis of the vehicle, a first transmission module, which includes a microcontroller and a transmitter for electromagnetic waves, is provided on the steering wheel. The microcontroller is designed to condition and convert electrical signals of operator control elements, arranged on the steering wheel, into signals which are suitable for the transmitter module. A second transmission module which includes a receiver and a microcontroller is arranged on a fixed region or chassis of the vehicle. The latter microcontroller is designed to convert signals which are received in the receiver into switching and/or control signals for electrical devices of the vehicle.
Abstract:
Disclosed herein is a system for enhancing the security of wireless networks. In one aspect, a wireless access point that functions as a bridge between two networks is provided. The wireless access point is configured to establish separate associations for itself and each device connected to it. This provides for enhanced security in that each device connected to the wireless access point may be separately authenticated and in that separate encryption tunnels are established for each device connected to the wireless access point.
Abstract:
A universal computer for a vehicle, comprising a microprocessor for the processing of control programs, a storage unit, for the data thus calculated and an interface which permits a connection of the computer to a databus in the vehicle. The computer comprises control programs for controlling device provided in the vehicle, whereby the control commands are transmitted to the device to be controlled via device interfaces. The computer also comprises reconfigurable hardware, which permits a retroactive reconfiguration of peripheral components or an interface in the assembled state of the computer. A transmission of an algorithm for reconfiguration of the hardware is provided to the storage unit on the vehicle, so that a process for reconfiguration of the hardware associated with the peripheral components or the interface may be carried out.
Abstract:
Disclosed herein is a networked media station providing a variety of features including a wireless network interface, a wired network interface, a peripheral interface, and a multimedia interface. The wireless network interface(s) allows the device to communicate to serve as a wireless base station or repeater and/or a bridge between a wireless and a wired network. The peripheral interface allows the device to communicate with a variety of peripherals, and, in conjunction with the network interface(s), allows sharing of a peripheral among multiple networked computers. The multimedia interface allows the device to be used with entertainment devices for streaming of multimedia information from a network connected computer to the entertainment device. Control of various aspects of the device is preferably controlled from a network connected computer.
Abstract:
Methods and apparatuses for synchronizing a system clock of a computer via a local gateway are described herein. In one embodiment, a local clock of a gateway device is periodically synchronized with a remote time service facility over an external network. The synchronized local clock of the gateway device is then used to synchronize a system clock of one or more clients over a local network without having the clients individually to access the remote time service facility. Other methods and apparatuses are also described.
Abstract:
A network media delivery system includes client devices and a host device. Each client device has a network interface, an engine for processing media data, and a media interface. The host device, which can be a computer, establishes network communication links with the client devices, which can be networked media stations, and sends media data to the client devices. The media data can be sent wirelessly as packets of media data transmitted at intervals to each client device. In one embodiment, the host device controls processing of media data such that processed media is delivered in a synchronized manner at each of the client devices. In another embodiment, the host device controls processing of media data such that processed media is delivered in a synchronized manner at the host device and at least one client device.
Abstract:
A data protocol converter has two interfaces, one of which can be connected to a standard vehicle diagnostic interface, and the other permitting wireless message transfer using a diagnostic handset. A data protocol translator converts the messages from the standard vehicle diagnostic interface into messages having a wireless data format, so that they can be received in the diagnostic handset using the latter's wireless interface. The data protocol converter has a further interface so that it can be connected to a second standard diagnostic interface according to a different standard. The data protocol translator can convert the messages from the second standard vehicle diagnostic interface into messages having a wireless data format.
