Title: Detection of amplified nucleic acid using secondary capture oligonucleotides and test kit
Inventor: WU ANNIE L
IPC: C12Q1/68
Filed: 1992-08-12
Abstract: DETECTION OF AMPLIFIED NUCLEIC ACID USING SECONDARY CAPTURE OLIGONUCLEOTIDES AND TEST KIT               Abstract of the Disclosure A target nucleic acid can be amplified and detected using a water-insoluble capture probe having a short oligonucleotide (15-20 nucleotides) covalently attached to a polymeric particle, and one or more secondary oligonucleotides.  The capture probe and secondary oligonucleotides are complementary to the target nucleic acid, although the sequences of complementarity are different.  Moreover, each of the secondary oligonucleotides has a length which is equal to or greater than the length of the capture probe oligonucleotide.  The secondary oligonucleotides are hybridized to the target nucleic acid either before or during hybridization of the target to the capture probe.  The result is improved hybridization efficiency of capture probe and target nucleic acid.

Title: Double refraction and total reflection solid nonimaging lens
Inventor: HOFFMAN MARC
IPC: G02B6/32
Filed: 1992-09-22
Abstract: ABSTRACT OF THE DISCLOSURE     A nonimaging lens consists of a solid body of light-propagating material defining a first light-refracting surface, a second light-reflecting surface and a third light-refracting surface.  To redirect the generally parallel light rays of a directional light beam, the first light-refracting surface diverges the light rays of this beam, the second surface reflects the  divergent  light  rays,  and  the  third  surface refracts these reflected light rays.  To concentrate dispersed light rays into a generally directional light beam, the third surface first refracts the light rays, the second light-reflecting surface converges these refracted light rays,  and the first surface refracts  the  convergent  light  rays  toward  the generally directional light beam.  In accordance with one embodiment, the first light-refracting surface and the second light-reflecting surface are conical, open out in opposite directions, and respectively define skewed refraction and reflection axes.

Abstract: Non-intrusive monitoring and analysis of real-time facsimile transmissions is accomplished. Analog impairment measurements are made on the high speed page signal in those transmissions and protocol analysis is made on the low speed control messages in those transmissions. These measurements and analysis are a powerful tool for trouble shooting service problems afflicting facsimile transmissions. Actual customer traffic can be monitored to detect circuit impairments and to evaluate service being provided. Customer complaints can be handled by providing them with a special phone number which may be called to provide the ability to have the facsimile transmission experiencing a problem specially directed through the facsimile analyzer and forwarded to the intended destination while it is being non-intrusively monitored by service personnel whothen can quickly provide the customer with a diagnosis of the problem.

Patent CA-2095720-A1 (CA)
Inventor: WOOD DAVID CHARLES
IPC: G06F15/18
Filed: 1991-11-08
Abstract: A method of training a neural network (2) having dynamically adjustable parameters controlled by a controller (10) which determine the response of the network (2). A set of input vectors (I l to I n) are input to network (2) at an input port (4). The corresponding set of output vectors (O'l to O'n) provided by the network (2) are compared to a target set of output vectors (O l to O n) by an error logger (12) which provides to the controller (10) a measure of similarity of the two sets. The controller (10) is arranged to alter the dynamic parameters independence on the average number of occasions the output vectors are different from the respective target output vectors. Measuring the similarity of the whole of the output set and target set and adjusting the parameters on this global measure rather than on the similarity of pairs of individual vectors provides enhanced training rates for neural networks having a data throughput rate that can be higher than the rate at which the parameters can be adjusted.
