Title: Accounting and billing based on network use
Inventor: TAPIA PABLO E
IPC: H04M15/16
Filed: 1999-12-03
Abstract: A method and system for determining billing information related to use of a network. For a data transmission path between a pair of nodes locations, the price for the transmission depends, inter alia, on the amount of data transported and the price of using the path of the network. The method collects traffic data for data sent over paths of network, creates a virtual path, which is a combination of one or more paths of network, selects a set of paths connecting each pair of node locations, and determines a price for the virtual path used to transport data between node locations. The determined cost of transporting data between node locations is then apportioned among the users of the network that transported the data.

Title: Door monitor for a gaming machine
Inventor: LOOSE TIMOTHY C
IPC: G08B21/18
Filed: 2001-08-01
Abstract: A door-monitoring system comprises a power supply electrically connected to an oscillator. The oscillator sends a signal to a junction between a switch to ground and a latch circuit. When the switch to ground is open, current flows from the oscillator to a set input on the latch, thus indicating that connections in the vicinity of the switch have been broken or the door has been opened. A microprocessor is adapted to receive output from the latch circuit and respond appropriately to an indication that the connections have been broken or the door has been opened.

Patent CA-2371073-A1 (CA)
Inventor: SIDERS KEITH E
IPC: H04L29/06
Filed: 2001-02-05
Abstract: A Modbus slave device is operable in an agile mode that allows the slave device to automatically in-terpret and respond to first-type and second-type message frames conveyed to the slave device by a master device. The slave device detects a first incoming character of a master query message frame generated by the master device. If the first incoming character is a prompt character for the first--type message frame, the slave device interprets the master query message frame as the first-type message frame. If the first incoming character is not the prompt character for the first-type message frame, the slave device interprets the master query message frame as the second-type message frame. If the slave device is addressed in the master query message frame, the slave device performs the command as-sociated therewith and, if required by the command, gener-ates a responsive slave message frame of the same type as the master query message frame.

Title: Process for removing systematic error and outlier data and for estimating random error in chemical and biological assays
Inventor: RAMM PETER
IPC: G16B40/00
Filed: 2000-06-19
Abstract: A method for improving the reliability and/or accuracy of physical measurements obtained from array hybridization studies performed on an array having a large number of genomic samples uses a small number of replicates insufficient for making precise and valid statistical inferences. This is overcome by estimating an error in measurement of a sample by averaging errors obtained when measuring the large number of samples or a subset of the large number of samples. The estimated sample error is utilized as a standard for accepting or rejecting the measurement of the respective sample. The samples may be independent or dependant in that correlated across two or more conditions.

Title: Electrical stimulation system and methods for treating phantom limb pain and for providing sensory feedback to an amputee from a prosthetic limb
Inventor: HOFFER JOAQUIN ANDRES
IPC: A61F2/02
Filed: 2000-07-05
Abstract: This invention relates to a system and methods for relieving phantomlimb pain in amputees, and for providing an amputee with sensory feedback from a prosthetic limb (40). The system employs implantable multichannel, multi-chambered interface structures, namely, nerve cuffs (30). The implanted nerve cuffs have electrodes (14) which transmit electrical signals generated by a signal generator (12) to nerves (20), recruiting certain neurons to send sensory signals to the cerebral cortex, suggesting sensory sensations to the amputee. Such signals can arise directly from the signal generator, approximating the train of signals seen by the cortex in a normally innervated limb, or can originate from sensors (50a-c) in a prosthetic limb.

Title: Dynamic-proximity suppression system tester
Inventor: DEROSIER PHILIP ARTHUR
IPC: G01M99/00
Filed: 2002-04-26
Abstract: A system and method for testing an airbag proximity suppression system is disclosed. The testing system includes a positioning system that controls movement of an occupant model inside of a vehicle and toward a suppression zone. A proximity detector provides a first output signal indicative of when the occupant model actually enters the suppression zone by monitoring movement of a position marker. The airbag suppression system, the device under test, provides a second output signal indicative of when the airbag suppression system detects that the occupant model has entered the suppression zone. The timing difference between the first and second output signals is indicative of a performance factor of the airbag suppression system. Further, a controller identifies a position of the occupant model when the airbag suppression system detects that the occupant model has entered the suppression zone. A comparison of the position of the occupant model relative to the boundary of the suppression zone is also indicative of a performance factor of the airbag suppression system.
