Abstract: Extended Digital Interface (XDI) provides systems, devices, connectors, signals, and methods to send 3D Vector and Motion based audio video serial digital signals through local systems or internet with significantly reduced bandwidth requirements and lower device costs, over longer cable runs. The XDI system has higher flexibility for connection topologies and scalability. The XDI system is much simpler to install employing the single coax cables and connectors, or internet, or Wi-Fi, which is simple and easy to work with, without introducing any signal quality losses or delays comparing to the current 2D Frame and Pixel based digital systems using multiple conductors like HDMI, DVI, DP or SDI when using the already compressed audio video content. The XDI system also provides solutions for integrating the uncompressed audio video content and Internet content into this system. These systems, devices, connectors and methods are collectively called “XDI” (Extended Digital Interface).

Abstract: The ability to efficiently determine the state of enzyme expression in cells has long been desired as material to the diagnosis of disease. This invention relates to cytoenzymology, and more particularly to improved reagents for use in cell-based assays, especially those using fluorogenic substrates.

Abstract: Formamide with low conductivity and a neutral or slightly basic pH is provided. Such formamide may be used in a sample loading solution for capillary electrophoretic separation of biomolecular analytes to enhance the efficiency of sample injection into the capillary and the intensity of the signal. Formamide of the present invention may be obtained by first purifying the formamide to a conductivity of below 7 micro mho, and then adjusting the pH of the purified formamide with a base to a range of about pH 6.5 to 7.5. The purification may be carried out by first removing the water from the formamide, and then distilling the dried formamide until the conductivity of formamide is below about 7 micro mho.
