Title: Fluid flow resistance monitoring system
Inventor: FARQUHAR ALLAN B
IPC: A61M5/168
Filed: 1997-07-28
Abstract: Flow parameters in a fluid delivery assembly are determined by monitoring pressure responses and processing those responses along with information regarding the fluid flow.      In one aspect, a processor controls the pump to pump flow quantities in accordance with a pseudorandom code.      Portions of the resulting pressure signal sensed at the conduit is averaged, and the averaged values are then decoded in accordance with the pseudorandom code. An estimate of the equilibrium pressure is generated from the decoded average pressure values, while a summation of the pressure samples is generated from the undecoded pressure signals. The resistance to fluid flow of the system is determined from the estimated equilibrium pressure and pressure summation. For low flow rates, a processor controls the pump to pump fluid in a series of fluid boluses, with each fluid bolus delivered in the beginning of a separate timeslot. The equilibrium pressure is measured at the end of each timeslsot, and a summation of the pressure samples is generated from the pressure signals. For high flow rates, the pump is controlled to vary the flow rate and the change in pressure is divided by the change in flow to directly determine the resistance. A resistance display continuously displays the resistance of the system. The pseudorandom coding and decoding can be used to filter out pressure-response crosstalk caused by multiple fluid infusion segments feeding into a common line.

Title: Method and apparatus for automated opening of options exchange
Inventor: LUPIEN WILLIAM A
IPC: G06Q40/00
Filed: 1997-09-08
Abstract: A computer-based system for determining a set of opening prices for a number of series of options traded on an options exchange and for allocating public order imbalances at the opening of trading. Market makers input a current position, a desired target position and market maker orders (104) for options series from market maker terminals. An order entry system receives public orders (102) for options series. A controller (2) determines a set of implied volatilities (prices) for each options series that will maximize a weighted volume of trades across all options series at the opening. Contra orders than can be matched at the opening price are then executed. If there is a residual imbalance of non-executed public orders, the residual imbalance of non-executed public orders is assigned to individual ones of the plurality of market makers so as to minimize a cumulative measure of deviation between the desired target position and the current position of each market maker. The system is applicable to an options exchange, this term including any facility operating an over-the-counter market in options.

Patent CA-2268848-A1 (CA)
Title: Hiv and cancer treatment
Inventor: CAMDEN JAMES BERGER
IPC: A61K31/27
Filed: 1997-11-26
Abstract: A method of treating HIV or other viral infections by administering a herbicide or fungicide or derivative thereof to an animal or human. The fungicides or herbicides can be used in conjunction with other treatments, e.g. with AZT or protease inhibitors for the treatment of HIV. For example, thiabendazole and chloropropham have been shown to quickly reduce the level of virus production from cell populations chronically infected with HIV-1 and the antiviral effect is maintained with continued compound exposure. This reduction of virus production occurs at concentrations which are non toxic to the host cell and which have no effect on the syntheses of cellular DNA, RNA and protein. Further, chronically infected cells treated for prolonged periods of time with thiabendazole and chloropropham were not super-infected with HIV. A method for inhibiting the growth of tumors and cancers in mammals comprising administering a herbicidal or fungicidal derivative is also disclosed herein. The fungicides or herbicides can be used in conjunction with other treatments, e.g. taxol for the treatment of breast cancer. Potentiators can also be included in the herbicidal or fungicidal composition. This method is particularly effective when the cancer or virus is an animal cell genetically modified by plant or fungus genetic material. A chemotherapeutic agent can also be administered first to significantly reduce the size of the cancer and then the treatment with the herbicide or fungicide is used. These methods are particularly effective when the cancer or virus is a mutated cell comprising plant or fungal genetic material.

Title: Channel assignment and call admission control for spatial division multiple access communication systems
Inventor: YUN LOUIS C
IPC: H04W16/14
Filed: 1997-12-30
Abstract: The methods for channel assignment and channel reassignment are suitable for SDMA systems that accommodate the dynamically adaptive spatial channel conditions and allow for more frequent reuse of conventional channels. Three methods for uplink channel assignment are described: a cost function method, a predictive method, and a hierarchical method. The cost function method computes a cost function for each conventional channel based on a weighted correlation matrix for spatial signatures of active subscribers. A spatial channel is created for the selected conventional channel if it is in use. The predictive channel assignment method predicts the uplink received power and interference-plus-noise for each conventional channel. Either the conventional channel with the minimum interference-plus-noise level or the channel with maximal SINR is selected, and a spatial channel is also assigned if the selected channel is in use. The hierarchical method combines the cost function method and the predictive method.

Patent CA-2284232-A1 (CA)
Inventor: INGLIS DAVID ANDREW
IPC: H04B3/23
Filed: 1999-09-28
Abstract: A mixed-mode crosstalk canceller is disclosed that performs crosstalk cancellation in the continuous time domain. The disclosed mixed-mode crosstalk canceller processes the pulse amplitude modulated (PAM) digital signal to be transmitted as well as the received signal to compensate for the crosstalk between the transmit and receive signals. The output of the crosstalk canceller is subtracted from the received signal in the continuous time domain. Thus, the transmit symbol clock and the receive symbol clock can be asynchronous. The tap weights for the crosstalk cancellation are illustratively obtained using a modified version of the least mean square (LMS) algorithm for discrete time signals. The modified least mean square (LMS) algorithm is applied for continuous time signals that are derived from different clocks. Since, the LMS  algorithm requires a costly multiplication of the error signal, e(t), and the digital transmit signal, x k (t), and it is only necessary to go in the direction of the gradient with the steepest decent, computational gains are achieved using a correlation multiplier that quantizes e(t) and x k(t) with only one or two bits. The quantized version of the error signal, e(t), indicates the sign of the error (positive or negative) and is obtained in the illustrative embodiment by comparing the error signal to zero. A crosstalk canceller updates each tap weight utilizing the disclosed correlation multiplier that provides a signal indicating whether the tap weight needs to be increased or decreased to a charge pump that produces a current in the proper direction.
