Title: Electrochemiluminescent enzyme biosensors
Inventor: MARTIN MARK T
IPC: G01N27/42
Filed: 1996-06-06
Abstract: Electrochemiluminescent enzymes, their preparation and use as biosensors are disclosed. Specifically, two appendages are covalently attached to a desired dehydrogenase enzyme; (1) a nicotinamide adenine cofactor or analog thereof, and (2) a luminescent ruthenium complex. For example, glucose concentration is the following way. A doubly-modified glucose dehydrogenase could oxidize glucose with concomitant reduction of the attached NAD+ to NADH. Because NADH, but not NAD+, is able to interact with surface ruthenium to promote ECL, only enzyme molecules that have reacted with glucose will emit light from their ruthenium label in an ECL instrument. The relative close proximity of NADH and ruthenium on the enzyme surface enhances light emission as compared to the same concentrations in free solution. When NADH reduces ruthenium, it returns to become NAD+, permitting multiple cycles of ECL light emission from a single enzyme molecule. Such biosensors can be used in solution or bound to a solid surface. Assays employing the biosensor molecules can be performed on an IGEN Origen Analyzer.

Patent CA-2242234-A1 (CA)
Title: Cooling structure of multichip module and method of manufacturing it
Inventor: YOSHIKAWA MINORU
IPC: H01L23/433
Filed: 1998-06-29
Abstract: A cooling structure is provided for a multichip module on which integrated circuit devices (i.e., LSI devices) having heat-radiation surfaces are mounted, wherein there are provided a heat sink, thermal conduction blocks and thermal compounds. Recess portions are formed at a surface of the heat sink in connection with the integrated circuit devices of the multichip module. Low melting point metal material such as solder is supplied to interiors of the recess portions of the heat sink. The thermal conduction blocks are partially inserted into the interiors of the recess portions under the condition where the low melting point metal material is heated and melted, so that the thermal conduction blocks temporarily float in the melted material. To avoid heat transfer toward the integrated circuit devices, a heat insulating sheet is provided on the thermal conduction blocks. Then, the low melting point metal material is solidified, so the heat insulating sheet is removed. The thermal compounds are placed on the thermal conduction blocks. Thus, the integrated circuit devices and the thermal conduction blocks are connected together by means of the thermal compounds. Because of temporary floating of the thermal conduction blocks in the melted material, it is possible to absorb dispersion in heights and slopes of the heat-radiation surfaces of the integrated circuit devices.

Title: Method and apparatus for on-line monitoring the temperature and velocity of thermally sprayed particles
Inventor: MOREAU CHRISTIAN
IPC: G01P5/22
Filed: 1998-10-28
Abstract: A method and an apparatus for monitoring simultaneously the temperature and velocity of a thermal spray jet. The apparatus has a sensor head directed at the jet, the sensor head having two optical fibers carrying radiation from the jet to a remote detection unit which comprises two or three photodetectors. The radiation carried by the separate optical fibers is filtered at two different wavelengths before being passed to the photodetectors. The temperature of the jet is determined by analyzing the ratio of the energy radiated at the two wavelengths. The velocity of the jet is determined, knowing the distance between the fibers, by measuring the time delay between the signals carried by the separate fibers using cross- correlation.
Patent CA-2253273-A1 (CA)
Title: System and method for sound synthesis using a length-modulated digital delay line
Inventor: STILSON TIMOTHY S
IPC: G10H7/08
Filed: 1997-05-06
Abstract: A sound synthesis system employs a variable-length delay line (154) whose length is modulated at a frequency that is close to the fundamental frequency of the delay line. By modulating the length of the delay line at a frequency close to the fundamental frequency of the delay line, a new class of sounds is generated. A delay line length modulator (156) produces a periodic modulation signal whose frequency is close to the fundamental frequency of the delay line. The length of the delay line is modulated in accordance with the modulation signal, thereby causing a variable pitch shifting effect in the waveform produced by the delay line structure. Since the length of the delay line (154) is modulated at a frequency close to the average loop frequency, part of the waveform stored by the delay line is time-compressed and the other part is expanded. The waveform's shape changes smoothly so that the compressed part of the waveform is pitch-shifted upwards, and the expanded part is pitch-lowered. A simultaneous upward and downward shift in the spectrum of the waveform stored by the delay line results, generating musically intriguing sounds. In one embodiment, a regeneration filter (252) introduces an instability into the delay line's feedback loop at a frequency of half the sampling rate. This introduces additional energy into the system which causes the waveform in the delay line (154) to regenerate, thereby increasing the length of time that sound effects are generated after the introduction of an excitation pulse.

Title: Novel sandwich liposome complexes comprising a biologically active agent
Inventor: PAVLAKIS GEORGE N
IPC: A61K47/16
Filed: 1997-08-01
Abstract: Highly efficient cationic liposomes have been developed as an improved delivery system for biologically--active reagents. A novel structure, the sandwich liposome, is formed and comprises one or more biologically active agents internalized between two bilamellar liposomes. This structure protects the incoming agent and accounts for the high efficiency of in vivo delivery and for the broad tissue distribution of the sandwich liposome complexes. These novel liposomes are also highly efficient carriers of nucleic acids. By using extruded DOTAP:cholesterol liposomes to form complexes with DNA encoding specific proteins, expression has been improved dramatically.     Highest expression was achieved in the lung, while increased expression was detected in several organs and tissues.

Title: Dispositif pour le controle de vehicules
Inventor: MUELLER ROLAND
IPC: G01M17/007
Filed: 1997-08-29
Abstract: L'invention concerne un dispositif au moyen duquel différents contrôles peuvent être effectués sur un véhicule, les pneus du véhicule étant chacun placés sur des rouleaux tournants pouvant être entraînés. Les dispositifs connus destinés au contrôle de véhicules sont d'un encombrement important et leurs coûts de fabrication sont élevés. L'objectif de l'invention est de permettre la réalisation de contrôle de véhicules avec un dispositif plus compacte et moins coûteux.
