On the edge

Motorola Labs, the applied research arm of Motorola Inc., produced a five-inch, color video display prototype based on proprietary carbon nanotube technology.CNT is a technique that Motorola officials said could create large flat panel displays with superior quality, longer lifetimes and lower costs than current technology. The technology is possible because of Motorola's Nano Emissive Display technology, which is a method of growing CNTs directly on glass.The prototype display's characteristics, such as fast response time, wide viewing angle and wide operation temperature, meet or exceed those for CRTs.Citrix Systems Inc. launched Citrix Presentation Server 4.0, a new version of its presentation server, that delivers data and applications on demand, company officials said.The new version supports up to 1,000 servers and 100,000 users, and can deploy a broader range of applications.With Citrix SmartAccess technology, administrators can control how enterprise applications are accessed. For example, a user may have full access to local drives and peripherals, but have restrictions when connecting from outside the network. Such restrictions could block downloading of confidential information and prevent the introduction of a virus. Xten Networks Inc.'s softphones software can be integrated into set-top boxes, embedded devices and instant messenger applications, company officials said. This applies to the software for Windows, Mac OS X, Pocket PC and Linux run on PCs and PDAs.When an Xten softphone is connected to a service provider's network, the user can make and receive calls with the same quality as an IP handset, according to Xten. Xten's eyeBeam feature set includes an array of telephony features including call transfer and forward, Caller ID and 10-point conferencing. eyeBeam also has video, instant messaging, audio and video recording, voice activity detection and message waiting indicator.
