Patent CA-2373516-A1 (CA)
Inventor: HART WILLIAM C JR
IPC: H03G3/30
Filed: 2000-04-28
Abstract: In a channelized system having a plurality of channels, an input spectrum having a plurality of signals is received by a receiver (10). A first attenuation value (V1) is applied to a first variable gain device (12) and a second attenuation value (V2) is applied to a second variable gain device (14), wherein the first variable gain device (12) and the second variable gain device (14) are within a common signal path. The receiver (10) is tuned to a desired channel and a first power level is measured within the desired channel. The receiver (10) is selectively tuned to at least one additional channel and a second power level within the at least one additonal channel is measured, independent of the first power level. Based on measuring the power levels, a first modified attenuation value is applied to the first variable gain device (12) and a seocnd modified attenuation value is applied to the second variable gain device (14).

IPC: H03F3/189

Abstract: Variable phase-shifting rf power amplifiers shift rf outputs at any angle up to 90, 180, or 270 degrees, respectively, while maintaining an rf output substantially constant. The variable phase-shifting rf power amplifiers include two to four field-effect transistors that are interposed between phase splitters and combiners, and that are connected in series between a source voltage and a lower voltage. Phase shifting is achieved by selectively and variably controlling amplification of the field-effect transistors. Selective and variable control of amplification is achieved by separately and variably controlling gate voltages of the field-effect transistors, whereby a difference between the source voltage and the lower voltage is used selectively by one of the field-effect transistors and selectively proportioned between two of the field-effect transistors. Phase controls generate separate and variable phase-shifting voltages, or gate voltages, in response to a variable phase-shifting voltage.

Abstract: Intracellular translocation of proteins, particularly protein kinase C (PKC) isoenzymes, provides a surrogate test system for determining toxicity of candidate compounds. The profile of translocation with respect to at least one and preferably two or more signal transduction proteins can be correlated with that of known toxins. In addition, databases of such profiles with respect to toxins of various types provide a useful set of standards for evaluating toxicity of candidate compounds. Moreover, to the extent that a toxin's profile mimics that found in a diseased state, the toxin can be used to construct screens for compounds alleviating the disease.

Title: Methods, systems, and kits for lung volume reduction
Inventor: WONDKA TONY
IPC: A61B17/00
Filed: 2000-06-29
Abstract: Lung volume reduction is performed in a minimally invasive manner by isolati ng a lung tissue segment, optionally reducing gas flow obstructions within the segment, and aspirating the segment to cause the segment to at least partial ly collapse. Further optionally, external pressure may be applied on the segmen t to assist in complete collapse. Reduction of gas flow obstructions may be achieved in a variety of ways, including over inflation of the lung, introduction of mucolytic or dilation agents, application of vibrational energy, induction of absorption atelectasis, or the like. Optionally, diagnostic procedures on the isolated lung segment may be performed, typical ly using the same isolations/access catheter.

Inventor: KING DOUGLAS W
IPC: G06Q20/02
Filed: 2000-09-07
Abstract: A method of and system (10) for authorizing purchases made over a computer network is provided. In accordance with the present invention, a consumer (12) electronically transmits an ATM card number over the network (24) to an on-line merchant (16) from which the consumer desires to make a purchase. The on-line merchant (16) then electronically forwards the ATM card number to a third party contractor (20), such as a bank, that will oversee and authorize the transaction. The third party contractor (20) subsequently determines an authentication token type associated with the card and electronically prompts the consumer for the appropriate type of authentication token, such as a PIN  or biometric signature or the like. The consumer (12) then inputs and electronically transmits the authentication token over the network to the third party contractor (20), bypassing the on-line merchant (16). Having both the ATM card number and the authentication token, the third party contractor (20) verifies that the ATM card number and authentication token are valid, checks for sufficiency of funds, and either authorizes or denies the transaction. The authorization or denial is communicated to the on-line merchant (16) over the network, who either completes or rejects the purchase.

Abstract: The invention relates to a method for linking two adjacent plastic work pieces (2, 3). The inventive method is characterized in that the intended contact zone (K) of at least one of the two work pieces (2) with which the latter adjoins to the other work piece (3) is at least partially subjected to a high-energy radiation to such an extent that the glass transition temperature is reduced in a marginal zone (R). The two work pieces (2, 3) are brought in the desired position relative to each other. For establishing the connection of the two work pieces (2, 3) at least the marginal zone (R) modified by the previous radiation process is heated at least in its surface area to a temperature that is higher than the glass transition temperature of the marginal zone (R) modified by the radiation process but lower than the glass transition temperature of the zones of the work pieces (2, 3) that have not been modified.  The invention also relates to an article (1) produced according to the inventive method that consists of two work pieces (2, 3) that are linked without using foreign matte. The inventive article is characterized in that recesses (V), especially channel-shaped recesses, are introduced in at least one contact zone (K) of the two work pieces (2).

Abstract: An energy delivery system for regenerative fuel cell vehicles includes a plurality of geographically distributed stations (100). Each station includes an external port (109) that supplies the chemical constituents for manufacturing hydrogen fuel on-board a vehicle. Specifically, the port provides water from a municipal water supply (124) and an electricity connection to the electrical transmission and distribution grid (122) and the building's local electrical distribution system (114). Additionally, the port provides for the transmission of data from the vehicle over the Internet to the electrical service providers that sell electrical power to retail customers over the distribution grid. Supply of power, and the flow of data, through the external port is automatically controlled via a port controller.  Each regenerative fuel cell vehicle is provided with a corresponding internal port (105) that supplies water and electricity, received from the external port through a connecting cable (107), to an on-board electrolytic hydrogen fuel production plant (120). An on-board energy management computer (624) controls the purchase of electricity by the vehicle from the station, the particulars of which may be negotiated over the Internet by the external port controller (103) and/or the internal on-board energy management computer.  Additionally, the vehicle can generate electricity from internally stored hydrogen, for delivery to the building's local electrical distribution system via the external station. The on-board energy management computer (624) controls the sale of electricity by the vehicle to the station, the particulars of which may be negotiated over the Internet by the external port controller (103) and/or the internal on-board energy management computer.
