Patent CA-2083845-A1 (CA)
Inventor: SMITH GARY J
IPC: G09F3/02
Filed: 1991-06-18
Abstract: Color change devices which are capable of undergoing a color change on bending. The devices comprise a flexible sub-strate (24) having a color generating metal (e.g. a valve metal such as Ta or Nb) at at least one surface and an intimately contact-ing optically thin anodic film (30) covering the color generating metal and generating a visible color by light interference and ab-sorption effects. The thin anodic film (30) is produced by anodizing the color generating metal in the presence of an adhesion-reducing agent (e.g. a fluoride) for weakening the normally tenacious bond between the anodic film and the metal. Devices of this kind capable of being activated by bending, as well as by separation of the constituent layers, are produced by carrying out the anodization step in the presence of a particular concentration of the adhesion reducing agent from a narrow range (e.g. 40-350 ppm of fluoride). The devices can be used as tamper evident labels and the like which show evidence of removal of the labels from articles to which they were originally attached as an indication of tampering.

Title: Production of outer membrane (om) proteins in gram-positive bacteria and recovery of protective epitopes
Inventor: SARVAS MATTI
IPC: A61P31/04
Filed: 1991-07-05
Abstract: ABSTRACT The invention provides a method for producing cloned outer membrane (OM) protein from pathogenic gram-negative bacteria. The invention also provides a method for renaturing the cloned outer membrane protein thus produced so the cloned OM protein regains immunologically active epitopes which are capable of eliciting production of antibodies, in mammals and other animals, that are bactericidal and can provide protection against infection by the pathogenic gram-negative bacteria. According to the method, DNA encoding outer membrane protein from gram-negative bacteria, known to be pathogenic in humans and animals, is expressed in a gram-positive bacterial host. The recombinant or cloned OM protein thus produced is then renatured so as to regain biologically or immunologically active epitopes which are capable of eliciting production of antibodies in animals and humans; the antibodies are bactericidal and protect the animals and humans from infection by the pathogenicgram-negative bacteria from which the gene encoding the cloned OMP's was derived. The method of the invention is exemplified in part by the production ofcloned and renatured class 1 outer membrane protein from Neisseria meningitidis, class 3 OM protein of Neisseria meningitidis and the OM protein OmpA of Escherichia coli.

Inventor: HAMBURG DOUGLAS R
IPC: F02B75/02
Filed: 1993-08-20
Abstract: Apparatus,  method  and  system  are  provided  for monitoring catalytic converter efficiency in treating exhaust gas from an internal combustion engine.   The air/fuel ratio fed to the engine is perturbed on a cylinder-to-cylinder basis above and below a mean or average air/fuel ratio.   The signal from an exhaust gas exposed to the exhaust gas sensor downstream of the converter for the perturbation interval is compared to  the  signal  for a  non-perturbation  interval.   A signal  is  generated  when  the  comparison  indicates catalytic converter   efficiency   below   a  minimum acceptable level.   The comparison may be carried out by comparing the difference in the mean value of the EGO sensor output signal for the perturbation and non-perturbation  intervals  to  a  preselected  and  stored reference value corresponding to the minimum acceptable efficiency.  The efficiency monitoring test system may be incorporated into fuel control means for controlling air/fuel ratio during normal engine operation.

IPC: H04N3/09
Filed: 1993-10-19
Abstract: ABSTRACT OF THE DISCLOSURE     A remote-reading IR thermometer is provided by means of which the temperature of an object can be measured in a non-contacting manner from a given distance, using a line detector on a screen scanning at a rate of approximately 25 Hz.  The thermometer includes an image-processing electronic system for providing  an  IR  image,  such  image being  homogenized  by detector elements which change from image to image to build up each line on the screen.   The thermometer also includes a blackbody radiator of known and regulated temperature.  Means are provided for the input of atmospheric correction factors into the image-processing electronic system.  The temperature of the object is determined by comparing the radiation output of the object with the output of the blackbody radiator.  A temperature-regulated reference surface is preferably used as the blackbody radiator in the thermometer and all the signals emanating from the object are related to the signal from this surface. Since atmospheric correction factors are input into the image-processing electronics, the atmospheric damping of the radiation output of the object is directly allowed for.

Title: Retraction apparatus and methods for endoscopic surgery
Inventor: MOLL FREDERIC H
IPC: A61B19/00
Filed: 1992-05-26
Abstract: A first inflatable retraction device has a first inflatable chamber (5) and a non-pressurized chamber (13) inside the main chamber. The non-pressurized chamber is expanded by inflating a second inflatable chamber (25). The non-pressurized chamber enables the main chamber to remain inflated when an aperture is cut in the envelope of the main chamber, through which treatment is carried out. A second inflatable retraction device has an inflatable retractor (103) and a maintainer (107). The inflatable retractor retracts the organ and the maintainer maintains the organ in its retracted condition after the inflatable retractor is deflated. The maintainer can be inflatable, and can be inside or outside the inflatable retractor. A self-retracting endoscope (201) has an optical assembly with an expandable retractor (211) fitted to its distal end. The distal end of the endoscope is inserted into the body with the retractor in a collapsed condition. The retractor is then expanded to retract organs that would otherwise obstruct the view from the distal end of the optical assembly. After observations are complete, the retractor is returned to its collapsed condition. An insertion tube (243) enables cylindrical objects, such as packaged inflatable retraction devices, to be pulled, instead of pushed, into the body. The additional chamber of an inflatable retraction device having two inflatable chambers is filled with a slurry of a particulate solid in a liquid. The liquid is removed and the additional chamber evacuated to consolidate the particulate solid. This increases the retracting strength of the additional chamber.

IPC: G11C29/56
Filed: 1994-01-20
Abstract: METHOD AND APPARATUS FOR DETECTING RETENTION FAULTS                    IN MEMORIES Abstract The present invention is directed to a method for detecting retention faults in each of a plurality of read/write memory elements (121 - 12z), arranged in a plurality of banks (141 - 14k) coupled in daisy chain fashion. Retention faults are detected, in accordance with the method, by signaling the banks in sequence, at each of three separate intervals, to cause the memory elements in each bank to execute a first, second and third sequence of read and/or write instructions. Execution of the second sequence of read and/or write operations is delayed so each memory element can be read after a prescribed interval to detect a first bit pattern written in each memory at the end of the first sequence. Similarly, execution of the third sequence of read and/or write operations is delayed so each memory element can be read after a prescribed interval to detect a second bit, complementary to the first pattern, written in the memory element at the end of the second sequence. By delaying theexecution of the second and third sequences of read and/or write operations, retention faults, if any, can manifest themselves.
Patent CA-2114066-A1 (CA)

IPC: H04L12/26
Filed: 1994-01-24
Abstract: A multiple node telecommunication system path identification technique enabling expedited path testing and/or monitoring, and providing rapid confirmation upon completion of a successful testing and/or monitoring function. The technique eliminates erroneous system alarms arising from a properly transmitted PID arriving at a given node prior to the receipt at that node of the correct PID from a system controller. This is accomplished by employing a memory at each system node capable of storing the most recent PID sent to the node by the system controller, the previous PID sent to the node by the system controller, and the PID received from another system node, or from a transmitter linked to a system transmission path. Each of the nodes within the telecommunication system facilitating the technique is further adapted to accept a PID received via a transmission path without triggering an alarm, if that received PID matches either the most recent or previous PIDs received from the system controller. The nodes are also configured to tolerate a mismatch between a PID received via a transmission path and the stored PIDs received from the system controller for a specified period of time before initiating an alarm, so that if the mismatch may be reconciled if it is merely an erroneous condition brought about by a delay incommunication between the node and the system controller.
