Patent CA-2221941-A1 (CA)
Inventor: FERRARO FRANK ANTHONY
IPC: B26B21/22
Filed: 1997-11-21
Abstract: Shaving systems having a first support,  at least one,  and preferably  a  plurality,  of  resilient  supports,  and  a plurality  of  skin-engaging  elements  movably  arranged  in spaced relation and supported by the resilient support.   The resilient  supports  normally  maintain  the  movable skin-engaging elements, e.g. blades, guards, and/or cap member, in spaced relation such that the movable, skin-engaging elements are spaced by a first distance, relative to each other, when the  skin-engaging  elements  are  in  a  normal,  unbiased position.   In one embodiment, when one or more of the skin-engaging  elements   is   acted  upon  by   forces   normally encountered during shaving, the resilient supports yield in order to move each of the blades and the cap into a more aggressive position.

Title: Spectrometer provided with pulsed ion source and transmission device to damp ion motion and method of use
Inventor: SPICER VICTOR L
IPC: H01J1/00
Filed: 1998-01-23
Abstract: A method and apparatus are provided for providing an ion transmission device or interface between an ion source and a spectrometer. The ion transmission device can include a multipole rod set and includes a damping gas, to damp spatial and energy spreads of ions generated by an ion source. The multipole rod set has the effect of guiding the ions along an ion path, so that they can be directed into the inlet of a mass spectrometer. The invention has particular application to MALDI (matrix-assisted laser desorption/ionization) ion sources, which produce a small supersonic jet or matrix molecules and ions, which is non-directional, and can have ions travelling in all available directions from the source and having a wide range of energy spreads. The ion transmission device can substantially spread out the generated ions along an ion axis. Consequently, a number of pulses of ions can be delivered to the time-of-flight or other spectrometer, for each cycle of the spectrometer.

Patent CA-2233122-A1 (CA)
Inventor: RAU PETER
IPC: H04Q11/04
Filed: 1998-03-25
Abstract: In a transmission system wherein redundant message cells, forwarded according to the ATM (Asynchronous Transfer Mode) transmission method during the course ofvirtual connections, are respectively transmitted via redundant transmission paths, a blocking window is defined upon reception of the message cells, this blocking window excluding from further processing those message cells with a lower sequence number than the sequence number of the message cell that was selected at the moment as the most recent message cell for further processing. The method avoids repetitions of message cells and yields an optimally low loss of message cells given a switching between the transmission paths.

Patent CA-2259502-A1 (CA)
Inventor: MONTROY JOHN THOMAS
IPC: H01L31/107
Filed: 1997-07-03
Abstract: An avalanche diode device that has a first layer of semiconductor material (12) and a second layer of semiconductor material (18) positioned thereon so as to define an interface (14). The first layer of semiconductor material (12) is a substrate and the second layer (18) comprises an avalanche layer wherein a depletion region is generated at the interface. The second layer (18) is preferably deposited on the first layer (12) through chemical vapor deposition epitaxial growth techniques. When photons enter the avalanche layer, a minority charge carrier is produced and, when the device is reversed biased, an avalanche of charge carriers is produced in the avalanche layer. Since the avalanche layer is deposited using epitaxial growth techniques, the uniformity of the layer produces higher gain uniformity. Further, the avalanche layer can be configured using the epitaxial growth techniques to have a gain region of higher dopant concentration located adjacent the interface with a spectral absorption layer with a lower dopant concentration interposed between the gain region and the surface that receive the photons. Hence, a higher quantum efficiency can be produced in an avalanche photodiode having this configuration while still maintaining a high degree of gain uniformity and low noise characteristics.

Title: Mutations of the 5' region of the human 5-ht1a gene, associated proteins of the 5' region and a diagnostic test for major depression and related mental illnesses
Inventor: LEMONDE SYLVIE
IPC: C12Q1/68
Filed: 1999-04-28
Abstract: Clinical response to antidepressant compounds correlates with a selective down-regulation of presynaptic 5-HT1A receptors in serotonergic raphe neurons.  Thus regulation of the 5-HT1A receptor gene could play a crucial role in the treatment or etiology of major depression. The promoter and repressor activities of the human 5-HT1A receptor gene have been examined. The analysis of the 5'-flanking regions of the 5-HT1A receptor gene has revealed a segment located between about -3438 and about -393 by upstream from the initiator ATG that mediates cell-specific repression of the gene that is greater in cells that do not express the 5-HT1A receptor.  The sequence of part of this region in patients with major depression were examined and a polymorphic C-G change located at -1017 bp was identified, which is associated with major depression. Thus, this sequence can be used as a genetic marker for major depression and related mental illnesses. A protein that binds to the DNA at the -1017 locus has been identified. Any such proteins that bind to the DNA at this region are important targets for the development of therapeutic compounds for the treatment of major depression and related mental illness that involve the serotonin system.  In addition the promoter region from about -393 to the initiator ATG displays glucocorticoid-mediated repression.

Title: Handing off a wireless terminal in a wireless telecommunications system
Inventor: MATUSEVICH ALEX
IPC: H04B7/26
Filed: 1999-04-27
Abstract: A wireless telecommunications system is disclosed that hands off a wireless terminal from one base station to another as the wireless terminal moves within a wireless telecommunications system. Each pair of communications channels (forward and reverse) that are used by the system for communication with a specific wireless terminal are not associated with a specific base station. Instead. the pair of communications channels are associated with the wireless terminal and are used by the wireless terminal both before and after a hand off. Before the hand off, the wireless terminal uses the pair of communications channels for communicating with a first base station. To accomplish the hand off to a second base station, the first base station stops using the communications channels at the same time that the second base station starts using them. Although the wireless terminal is handed off from the first base station to the second base station, re-tuning of the wireless terminal is not required.
