Title: Procede et appareil permettant de liberer une trame afin de faciliter la detection d'un transfert de controle dans un systeme de communications a acces multiple par repartition de code
Inventor: DECLERCK DANIEL J
IPC: H04W36/08
Filed: 1998-02-18
Abstract: Cette invention concerne une station mobile (106) utilisée dans un système de communications à accès multiple par répartition de code (100) (AMRC). Cette station mobile (106) va effectuer un balayage des canaux pilotes sur une fréquence différente en réservant une trame périodique sur le canal avant, ceci de manière à ce qu'elle puisse changer de fréquences et effectuer des balayages sur d'autres canaux pilotes. Afin de conserver certains critères de qualité vocale, la station de base (102) et la station mobile (106) vont toutes deux coder les signaux vocaux selon un maximum d'un demi-débit, puis transmettre les informations sous forme de trafic secondaire avant la trame dans laquelle la station mobile (106) balaye l'autre fréquence. Afin de maximiser le compromis entre la qualité vocale et la fréquence de balayage, la station de base (102) va indiquer par messagerie à la station mobile (106) la période séparant les autres balayages de fréquence. Afin d'assurer la compatibilité, ce procédé peut faire l'objet de discussions en ayant recours aux techniques connues de négociation des configurations de services.

Patent CA-2302730-A1 (CA)
Inventor: STEPHENSON JOHN
IPC: F24B1/181
Filed: 2000-03-21
Abstract: The subject invention describes a portable/transportable Patio or Camp-site Heater, or Fire-pot, in which the preferred embodiment uses a partially manufactured, new or discarded propane cylinder modified by the addition of a chimney and metal stand. Ventilation holes are cut into the base of the cylinder so as to provide primary combustion air to the fuel inside the cylinder. An oval hole cut into the front lower half of the cylinder is designed to provide secondary combustion air to the fire, and to allow the user to see the conflagration. It is designed to consume relatively small amounts of fuel in a manner which creates intense heat inside the 'OTPOT. This heat is transferred to the walls of the pot and its chimney so as to raise the temperature of the metal to the point at which it radiates significant amounts of heat to the surrounding seated persons. The design enables the fire to consume smoke particles (so that little smoke is emitted from the chimney), and also ensures that the combustion products released from the chimney are at a high temperature, so that they rise rapidly into the atmosphere and minimize inconvenience to the surrounding seated persons. The preferred embodiment of this invention uses solid fuel - wood, charcoal, or briquettes. The 'OTPOT can also be used to cook food (e.g.roast potatoes or corn), roast marshmallows or other tid-bits, or to boil liquids or fry food. The design has a low centre of gravity and a stable stand, and it can be fitted with spark guards to minimize risks of fire in adjacent property. It can stand on open ground or in a metal tray depending upon local needs, and it is easily portable. The 'OTPOT is expected to have a useful lifetime of several years.

Title: Programmable sub-surface aggregating metallization structure and method of making same
Inventor: KOZICKI MICHAEL N
IPC: G11C13/02
Filed: 1998-12-04
Abstract: A programmable sub-surface aggregating metallization sructure ("PSAM") includes an ion conductor such as a chalcogenide-glass which includes metal ions and at least two electrodes disposed at opposing surfaces of the ion conductor. Preferably, the ion conductor includes a chalcogenide material with Group IB or Group IIB  metals. One of the two electrodes is preferably configured as a cathode and the other as an anode. When a voltage is applied between the anode and cathode, a metal dendrite grows from the cathode through the ion conductor towards the anode. The growth rate of the dendrite may be stopped by removing the voltage or the dendrite may be retracted back towards the cathode by reversing the voltage polarity at the anode and cathode. When a voltage is applied for a sufficient length of time, a continuous metal dendrite grows through the ion conductor and connects the electrodes, thereby shorting the device. The continuous metal dendrite then can be broken by applying another voltage. The break in the metal dendrite can be reclosed by applying yet another voltage. Changes in the length of the dendrite or the presence of a break in the dendrite affect the resistance, capacitance, and impedance of the PSAM.

Title: Bir-4-si rf pulses, use therefor and method of creating the same
Inventor: COTE JEAN-CHARLES
IPC: G01R33/48
Filed: 2000-06-29
Abstract: Adiabatic RF pulses are very useful in MRI when precise flip angles are needed. Unfortunately, adiabatic pulses suffer from a long application time and a high SAR. A new concept to modify the usual adiabatic pulse into a "pseudo-adiabatic" pulse having a shorter application time and lower SAR is introduced. For example, a BIR-4 of 32 ms of application time and a relative SAR of 20 will be transformed into a BIR-4-S1 of 1 ms and relative SAR of 1. The new pulse obtained stays insensitive for a large B1 range but loses its slice selectivity to become a 3D pulse. Experimental results are presented to illustrate the sensitivity to B1 and B0.

Title: Electrical control apparatus for leased equipment
Inventor: SIFRIM RUBEN I
IPC: G07B15/00
Filed: 2000-07-21
Abstract: An electrical control system preferably for vehicles such as a transit vehicle is arranged with a plurality of separate modules each receiving input from a series of inputs and each providing a series of outputs so that the modules combined receive inputs from all of the control, transducer and other input elements of the vehicle and the modules as a whole provide output to all of the controlled elements of the vehicle. The modules communicate between one another via a communication bus and an operational program is installed in each of the modules so that all modules contain programming for the functions of each module. A replacement module is generic and thus can contain any operational program and thus can be used for many different designs of the system. As supplied, the module may contain an existing program or no operational program if not yet programmed. On a subsequent power-up after installation of the replacement module, a check program is run to determine that a replacement module is in place and to download the operational program from a selected one of the existing modules into the replacement module. This allows service personnel to readily install replacement modules without the necessity for dedication of the modules to specific design schemes. The modules can be programed securely with an expiry date which allows unauthorized operation of the vehicle to be disabled in the event that the expiry date passes, for example at the end of a lease.

Title: Nucleobase oligomers
Inventor: FISHER PETER V
IPC: C12Q1/6844
Filed: 1998-12-21
Abstract: A novel class of compounds, exemplified by oligomers comprised of purine, pyrimidine, and other nucleobase monomers are disclosed. The nucleobase oligomers hydrogen bond through Watson/Crick base pairing to complementary nucleic acids, such as DNA and RNA, in an opposing strand. Each internal nucleobases in the oligomer has two attachment sites and is attached to two nucleobases by linkers. Terminating groups may contain reactive functionality, labels, reporters, or nucleic acids. The nucleobase oligomer compounds are useful as sequence specific recognition molecules for complementary nucleic acids. Where the molecule consists of sections of nucleobase oligomer and nucleic acid, the chimera may be an enzyme substrate in cleavage, ligation, and primer extension methods such as PCR and DNA sequencing.
