Title: Liquid crystal projection display
Inventor: JONES PHILIP J
IPC: G02F1/1334
Filed: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE    This invention provides a liquid crystal projection display, comprising (a) light source means for producing; (b) image forming means comprising plural pixel elements, each pixel element comprising liquid crystal material dispersed in plural volumes in a containment medium and being independently operable to primarily scatter light incident thereon in the absence of a sufficient electric field and to primarily transmit light incident thereon in the presence of a sufficient electric field, the liquid crystal composition including a pleochroic dye which, in the absence of the sufficient electric field, preferentially absorbs light in the spectral region in which the amount of light scattering by the image forming means is lowest and which, in the presence of the sufficient electric field, transmits such light, to thereby balance the color of the light scattered or transmitted by the image forming means; and (c) lens means for projecting light transmitted by the image forming means onto a screen.

Patent CA-2143145-A1 (CA)
Inventor: DEVANBU PREMKUMAR T
IPC: G06F11/36
Filed: 1995-02-22
Abstract: Techniques for obtaining information about dynamic properties of a program.  The techniques involve programming a programmable execution environment such as a debugger so that when the program is executed in the execution environment, side effects of the execution provide the information about the dynamic properties.  The program for the execution environment is produced by a source code analyzer which statically analyzes the source code. The source code analyzer is in turn produced by a code analyzer generator. Output from the execution environment may be provided to a graphical display system. In one use of the techniques, the code analyzer generator not only generates a source code analyzer for producing the program for the execution environment, but also a source code analyzer for producing a program which when executed by a graphical browser makes a flow graph for the program.  In this case, the graphical browser responds to the output from the execution environment by altering the appearance of the flow graph.

Title: Homogeneous immunoassays using mutant glucose-6-phosphate dehydrogenases
Inventor: JAKOBOVITS EDWARD B
IPC: C12Q1/28
Filed: 1994-04-07
Abstract: The present invention relates to methods for ummunoassay of analytes employing mutant glucose-6-phosphate dehydrogenase (G6PDH) enzymes as labels. In particular, the invention relates to the use of conjugates of an analyte or analyte analog and a mutant NAD+ dependent G6PDH differing from any precursor G6PDH by the deletion, substitution, or insertion, or any combination thereof of at least one amino acid per subunit. The invention also involves the construction of several mutations in precursor glucose-6-phosphate dehydrogenase (G6PDH) enzymes. Typically, the mutations involve deletion or substitution of one or more lysine residues, or introduction of one or more cysteine residues by insertion of cysteine to precursor G6PDH or substitution of precursor G6PDH amino acids residues with cysteine. The present invention also relates to conjugates of the subject enzymes and specific binding pair members, kits useful in performing the methods of the invention, cell lines producing the subject enzymes, DNA sequences encoding the subject enzymes, and vectors containing DNA encoding the subject enzymes and designed to allow a host cell to produce the subject enzymes.
