Patent CA-2457969-A1 (CA)
Title: System and method for improving the balance between download and upload traffic on the internet and/or other networks
Inventor: MAYER YARON
IPC: H04Q7/20
Filed: 2004-01-14
Abstract: Fast connections of end users to the Internet are becoming more and more common today, and the most common types of these fast connections are ADSL and cable modems. These connections are typically highly asymmetric and allow typically 500-1500 KBit per second (most typically 750 Kbit) for the downlink and typically for example 64KBit or 96Kbit per second for the uplink (although standard ADSL can in principle support up to 8Mbit per second download speed and up to 800Kbit per second upload speed), based on the assumption that most users download much more data than they upload. However, at least for some users these limitations are highly undesirable, and these are for example users or small businesses or organizations who want to use the connection also for example for VOIP (voice over IP) communications or Video-over IP communications or conferences or for example running web servers. Actually ADSL is beginning to be replaced by VDSL in places where the distance to the nearest street switchboard is about 1.2 Kilometers or less, which in principle allows up to 52 Mbit per second Download speed and up to 16Mbit per Second Upload speed. However, even when end users become connected directly by fiber-optics, the typical ratio of much more Downlink versus Uplink will remain. The present invention tries to solve the problem for users who need constantly or on a changing basis more Uplink by preferably allowing users to preferably temporarily change their Uplink-Downlink ratio on a need basis while preferably keeping the general balance across users. Other variations allow also compensating for example for variations of the average ratio across users for example according to time of day.

Title: Segmented balloon catheter blade
Inventor: HERBERT R RADISCH JR
IPC: A61B17/00
Filed: 2002-04-04
Abstract: A device (10) for incising a stenosis in the vasculature of a patient includ es a plurality of blades (28A, 28B, 28C) mounted on a resilient base member.(26 ) The blades (28a, 28b, 28c) are arranged in a pattern to allow for relative movement between adjacent blades. Specifically, at least one end portion of each blade is juxtaposed with an end portion of the next closest blade. The base member, (26) in turn, is mounted on the external surface of an inflatab le angioplasty balloon (14). When the balloon (14) is inserted into the vasculature of a patient, positioned across a stenosis and subsequently inflated, the individually moveable blades (28a, 28b, 28c) form an effective cutting edge that conforms to the surface of the stenosis to effectively all ow the stenosis to be incised to a substantially uniform depth.

Title: Rf receptive filter adhesive
Inventor: SEMRAD ROBERT E
IPC: B01D39/00
Filed: 2005-01-10
Abstract: A filter manufacturing process includes the steps of dispensing an adhesive including an RF receptive material, and arranging the adhesive between an end disc and a filter media. The adhesive is exposed to RF waves excite the RF  receptive material, which generates heat to cure the adhesive. The adhesive need only be exposed to the RF waves for several seconds. As a result, the filter media may be fully cured during the early processing stages. In one example, the adhesive is a vinyl adhesive plastisol. The filter media and end disc are passed through a curing tunnel in which an RF transmitter is arranged proximate to the adhesive to emit RF waves to excite the RF receptive material.

Abstract: There is provided herein a support surface such as a bed or chair which contains a network of inelastic straps, the tension in each of which can be independently sensed and adjusted under control of an electronic monitor. Preferably, each strap will contain a plurality of sensors to allow an attached electronic monitor (preferably one with a microprocessor) to determine in real time the amount of pressure (or the duration of the pressure) applied to each strap. Based on that information, the attached monitor will periodically loosen or tighten the straps as needed to move support for the patient's body away from current pressure points. In one preferred arrangement, each strap will preferably be loosened or tightened through the use of a worm gear drive or similar mechanical motor.

Inventor: BOYD WALTER
IPC: F01D5/18
Filed: 2004-01-05
Abstract: A circulator device comprising a large diameter fan having reinforced fan blades with a tapered airfoil shape is disclosed. The fan blades may be formed using an extrusion method of fabrication, wherein each fan blade (316) may comprise a reinforced trailing edge (514) with a downwardly extending flange.  The benefit of forming each fan blade with a reinforced trailing edge (514) of the present invention results in improved structural characteristics such that the trailing edge of each fan blade (316) may be fabricated longer so as to improve aerodynamic performance. Also, the reinforced trailing edge resists tearing that my occur during extrusion by adding the bent flanged region to at least one distal end of the trailing edge. For example, the bent portion (538) of the trailing edge tends to rigidly orient the extruded material in a stabilized position more readily during formation.

Title: Multiprocessor computer architecture incorporating a plurality of memory algorithm processors in the memory subsystem
Inventor: LESKAR PAUL A
IPC: G06F12/00
Filed: 1998-12-03
Abstract: A multiprocessor computer architecture incorporating a plurality of programmable hardware memory algorithm processors (MAPs) in the memory subsystem. The MAP may comprise one or more field programmable gate arrays (FPGA), which function to perform identified algorithms in conjunction with, and tightly coupled to a microprocessor and each MAP is globally accessible by all of the system processors for the purpose of executing user definable algorithms. A circuit within the MAP signals when the last operand has completed its flow thereby allowing a given process to be interrupted and thereafter restarted. Through the use of read only memory (ROM), located adjacent to the FPGA, a user program may use a single command to select one of several possible pre-loaded algorithms thereby decreasing system configuration time. A computer system structure MAP may function in normal or direct memory access (DMA) modes of operation and in the later mode, one device may feed results directly to another thereby allowing pipelining or parallelizing execution of the user defined algorithm.  The system also provides a user programmable performance monitoring capability and utilizes parallelizer software to automatically detect parallel regions of the user applications containing algorithms that can be executed in the programmable hardware.
