Abstract: A thin client intelligent transportation system wherein geospatial roadmaps and map matching systems are maintained in roadside nodes and are more fully exploited. The thin client approach offers significant advantages over thick client approaches that rely on on-vehicle maps and map matching systems, including reduced complexity of on-board equipment and elimination of map integrity issues. The thin client approach also offers significant advantages over systems wherein the vehicle is required to access maps and map matching systems in real-time from a remote data center, including the ability to meet the low latency requirements for many vehicle safety applications. The present invention in some embodiments has added advantages in that it exploits roadside maps and map matching systems in revenue generating applications that are not directly related to passenger safety.

Abstract: A modular, scalable, extensible, In-Flight Entertainment (IFE) data communication system is described. In one embodiment, a server/switch line replaceable unit including at least one server, at least one switching element and a plurality of fiber optic transceivers communicates with a plurality of passenger seat video display units over fiber optic cables. A server, such as, for example, an audio server, a video server, an audio/video server, a game server, an application server, a file server, etc, provides data (e.g., entertainment programming, internet file data, etc.) to the video display unit. In one embodiment, a hybrid switch unit provides flexible communication between one or more servers and the passenger seats.

Abstract: A remote interface network in which multiple remote HID encoder/decoder units share a common physical transport medium for connecting to one or more processing unit encoder/decoders is described. In one embodiment, the physical transport medium includes an optical shared media transport network. Each remote HID encoder/decoder unit can support one or more remote HIDs. The processing unit encoder/decoder can support one or more Pus. The network can be used, for example, in office, hospital, dense seat (e.g., aircraft, bus, etc.) and content provider networks.
