High Definition Printing.

High-resolution electrohydrodynamic jet printing.

Efforts to adapt and extend graphic arts printing techniques for demanding device applications in electronics, biotechnology and microelectromechanical systems have grown rapidly in recent years. Here, we describe the use of electrohydrodynamically induced fluid flows through fine microcapillary nozzles for jet printing of patterns and functional devices with submicrometre resolution. Key aspec...

High-Definition Vector Imaging

■ High-definition vector imaging (HDVI) is a data-adaptive approach to synthetic-aperture radar (SAR) image reconstruction based on superresolution techniques originally developed for passive sensor arrays. The goals are to produce more informative, higher-resolution imagery for improving target recognition with UHF and millimeter-wave SAR and to aid the image analyst in identifying targets in ...

Experiences with High Definition

We review the design and implementation of UltraGrid, a new high definition video conferencing system, and present some experimental results. UltraGrid was the first system to support gigabit rate high definition interactive video conferencing on commodity systems and networks, and we present measurements to illustrate behavior of production networks subject to such real time traffic. We illust...

High Definition (HD) Video

The HD video stream display (receiving) uses either a software-based solution with color depth down-sampling and field de-interlacing, or another Centaurus card. Data distribution to individual participants of the videoconference is achieved using a user-controlled UDP packet reflector based on the Active Element idea. The viability of this system has been demonstrated at the iGrid 2005 confere...
