Title: A method for aperturing a laminate
Inventor: MORIMOTO KOICHI
IPC: A61F13/15
Filed: 1998-08-28
Abstract: The present invention relates to a method for aperturing a laminate (32). The first step is to provide a laminate (32) having at least one nonwoven web of thermoplastic fibers (22, 24) and at least one elastic member (50). The laminate (32) is forwarded through a pressure biased nip having a relief patterned nip defining member (150) having a plurality of pattern elements (151) and a nip defining anvil member (124). The nip defining members (151) are biased towards each other with a predetermined pattern-element loading. Each nip defining member (124, 152) is heated to a temperature that is sufficiently above the melt temperature of the thermoplastic fibers of the nonwoven web and above the melt temperature of the elastic member to enable aperturing of the laminate (32).

Patent CA-2312018-A1 (CA)
Inventor: JABAJI ISSAM
IPC: H02P9/48
Filed: 2000-06-20
Abstract: An alternator regulator controls both output voltage and output current, limits input drive power and torque, and maintains output power within a prescribed range while operating over a wide ambient temperature range and shaft speed range. Voltage, shaft speed, and temperature signals are monitored, and the results are processed to determine the output current and to control the output power without exceeding the programmed limits for output voltage, output current, temperature; output power, drive power, torque, and shaft speed. This provides a predictable output power characteristic for the alternator and it eliminates high input drive power and torque excursions that occur at low temperature and certain shaft speeds. If programmed limits are exceeded over a specified interval, and the alternator does not respond to the control changes imposed by the regulator, the regulator will turn off the alternator's field current, activate an alarm circuit, and set fault codes. The regulator is also capable of communicating with other control systems to provide status, specify needs, and respond to requests.

Title: Mass spectrometry from surfaces
Inventor: WHITEHOUSE CRAIG M
IPC: H01J49/16
Filed: 1999-01-22
Abstract: A Time-Of-Flight mass spectrometer (1) is configured with a pulsing region (10) and electronic controls to cause the directing of ions to a surface (12) in the Time-Of-Flight pulsing region (10). The population of ions resulting from the collecting of said ions on or near said surface (12) is subsequently accelerated into the Time-Of-Flight tube (17) for mass to charge analysis. Ions produced away from said surface (12) can be directed to the surface (12) with high or low surface collisional energies.      Higher energy ion collisions with the surface (12) can result in Surface Induced Dissociation fragmentation and the resulting ion fragment population can be mass analyzed. Mass analysis can be performed prior to directing the ions to the surface allowing MS/MS Time-Of-Flight mass analysis with SID. Ion to surface low energy collisions or soft landings resulting in little or no ion fragmentation provide a means for spatially focusing ions on or near the surface prior to accelerating the surface collected ions into the Time-Of-Flight tube.

Title: Methods for processing operator services system calls
Inventor: DOWNUM WESLEY
IPC: H04M7/00
Filed: 2000-01-03
Abstract: To distinguish multiple operator services systems (OSS) and provide services within a single local area telephone network, originating end telephone offices include database tables that correlate end user telephone numbers to selected OSS providers. When an OSS-type call is placed to an originating end office (OEO), the OEO uses the database to correlate the calling party's number to a code corresponding to the OSS provider. In one embodiment, this code is used to populate at least part of the ISUP called party number digit field of the SS7 signaling protocol. This number, as well as the original called party number are transmitted to the switching network which relies on the called party number digits field to route the call to the appropriate OSS.
Patent CA-2325710-A1 (CA)
Inventor: KRYSTEIN JOHN PER
IPC: B65G23/22
Filed: 1998-02-20
Abstract: A method and apparatus for converting a conventional mechanical or hydraulic system for driving the infeed and outfeed rolls of a planer mill or a similar conveyor to variable frequency electric power. The method involves disconnecting the roller shafts from pre-existing mechanical and hydraulic drive components housed within the conveyor gearbox or other support frame. The electric motors are mounted at fixed positions on a panel rigidly connected to the gearbox or other support frame at a location spaced-apart from the roller shafts. Each motor is coupled to a corresponding roller shaft by means of a connector drive shaft having universal joint couplers at each end thereof. This arrangement permits displacement of the roller shafts during normal operation of the conveyor without transferring torque forces to the electric motors. The speed of each motor and hence each roller may be independently controlled by a frequency inverter which is operable by remote control.
Patent CA-2327547-A1 (CA)
Title: Oligonucleotides containing pyrazolo[3,4-d]pyrimidines for hybridization and mismatch discrimination
Inventor: KUTYAVIN IGOR V
IPC: C12Q1/6818
Filed: 1999-04-05
Abstract: Oligonucleotides in which one or more purine residues are substituted by pyrazolo[3,4-d]pyrimidines exhibit improved hybridization properties. Oligonucleotides containing pyrazolo[3,4-d]pyrimidine base analogues have higher melting temperatures than unsubstituted oligonucleotides of identical sequence. Thus, in assays involving hybridization of an oligonucleotide probe to a target polynucleotide sequence, higher signals are obtained. In addition, mismatch discrimination is enhanced when pyrazolo[3,4-d]pyrimidine-containing oligonucleotides are used as hybridization probes, making them useful as probes and primers for hybridization, amplification and sequencing procedures, particularly those in which single- or multiple-nucleotide mismatch discrimination is required.
Patent CA-2328352-A1 (CA)
Inventor: PARK CHANG-SOO
IPC: H04J13/00
Filed: 2000-02-14
Abstract: Disclosed is a power control method for a mobile station which has at least one frame including a data transmission duration where data is transmitted at a first frequency, and a data transmission-off duration where a second frequency is searched to perform an inter-frequency handoff to the second frequency. The transmission power at the data transmission duration is increased to compensate for the loss of transmission power during the data transmission-off duration. In the method, a base station sets a power control threshold depending on the length of the data transmission-off duration. The base station receives power-increased data and compares the received power of the data signal with the power control threshold. The base station generates a power-up command when the power control threshold is higher than the receiving power, and generates a power-down command when the power control threshold is lower than the receiving power.

A player continues playing until the numbers remaining in the series do not add up to the total displayed by the low vision die or dice. Whereupon; play passes to the next player.      The number(s) remaining in the series at the end of each players turn are recorded with the player achieving the lowest or highest score (depending on rules of play) winning the game. The game may be played using any practical number series and a low vision die or dice. A method of playing the present game is also disclosed.
Patent CA-2329782-A1 (CA)
Inventor: RISE MARK T
IPC: A61N1/05
Filed: 1999-04-12
Abstract: The present invention discloses techniques for warning a patient of a possible onset of a seizure using a sensor, a signal generator and at least one implantable electrode. The electrodes are positioned to stimulate the spinal cord or under the skin. The sensor senses a parameter of the body indicative of the possible onset of a seizure. The sensor generates a sensing signal which is processed and an algorithm is utilized to determine whether the sensing signal shows a pattern indicative of a possible seizure onset. If such a pattern is recognized, the signal generator provides electrical stimulation via electrodes to generate a sensory stimulus to the body. The stimulation may provide visual, aural or touch stimulus to the patient. The patient is thereby alerted to the possibility of a seizure onset and may take appropriate action.
