Patent CA-2396851-A1 (CA)
Title: Ionic enhanced dialysis/diafiltration system
Inventor: COLLINS GREGORY R
IPC: B01D61/14
Filed: 2001-01-11
Abstract: A dual-stage filtration system and methods for using the same include first and second filtration cartridges (122, 138) particularly suited for hemodiafiltration and/or hemodialysis.  As fluid enters the first filtration cartridge (122), the hydrogen ion concentration (pH) is reduced by exposing it to an acidic solution such as citric acid across a filter membrane (124). This stage allows for improved removal of certain toxins in the fluid, such as protein-bound substances that disassociate more readily from proteins at a lower pH. As the filtered fluid enters the second filtration cartridge (138), the pH of the fluid is restored to normal levels prior to infusion to a patient.

Filed: 1998-06-18
Abstract: A signal adaptive filtering method for reducing blocking effect and ringing noise, a signal adaptive filter, and a computer readable medium. The signal adaptive filtering method capable of reducing blocking effect and ringing noise of image data when a frame is composed of blocks of a predetermined size includes the steps of: (a) generating blocking information for reducing the blocking effect and ringing information for reducing the ringing noise, from coefficients of predetermined pixels of the upper and left boundary regions of the data block when a frame obtained by deconstructing a bitstream image data for inverse quantization is an intraframe; and (b) adaptively filtering the image data passed through inverse quantization and inverse discrete cosine transform according to the generated blocking information and ringing information. Therefore, the blocking effect and ringing noise can be eliminated from the image restored from the block-based image, thereby enhancing the image restored from compression.

Title: Solid angle cross-talk cancellation for beamforming arrays
Inventor: SMITH STEVEN SHAWN
IPC: H04R1/00
Filed: 2002-03-14
Abstract: A non-adaptive system and method for improving on-axis pickup of a signal by a transducer, such as a microphone, where the signal received by the transducer can be spatially represented as lobes or beams, the on-axis pickup being improved by removing the side portions of the beams. The input signal, or signals, has a prede termined location, whether that is at zero degrees on a polar plot or elsewhere, and the system produces an output beamwidth as narrow as possible. The input beams of the signal (or signals) received are processed to produce cancellation beams, and the cancellation beams are then steered, using phase or time delays, to overlap with the desired input beams outside of the desired output beamwidth. Via superpositioning, the cancellation beams are then subtracted from the desired input beams resulting in an output beam with a narrower beamwidth, and thus improving on-axis pickup by automatically excluding portions of the beam considered likely to be interfering sources or generally undesirable signal.
