Abstract: A machine for conducting dialysis of body fluids of a patient. The machine includes integral water preparation and treatment, dialysate preparation, and extracorporeal circuit modules, under computer control from a patient interface and control module. A  water pretreatment module with a temperature-controlled mixing valve, an integral water filtration and conditioning unit and a pressure relief with integral water sample removal port supplies water to the machine. The dialysate preparation module includes a substantially non-compliant tank with attached batch chemical bottles and automatic chemical addition and dispersion subsystems. The machine incorporates novel automatic process control techniques to verify the status and integrity of the critical system components, ultrafiltration control, and temperature, pressure and conductivity conditions prior to dialysis.

Title: Method and system for allocating and redeeming incentive credits between a portable device and a base device
Inventor: BIORGE JAMES E
IPC: G06Q20/40
Filed: 1995-02-02
Granted: 2004-04-20
Abstract: A customer incentive system involving a plurality of service or merchandise providers comprises a customer-carried, portable device (74), a provider device (76), and a base device (72).  To earn incentive credits, the customer enters into a transaction with one of the providers participating in the incentive system (70).  A transaction amount is derived from the transaction and, based on this  amount, an incentive credit amount is computed.  The base device (72) performs this computation by deriving an incentive code and cross-referencing  this incentive code with all customer incentive codes stored on the customer-carried device (74) and  incentive program codes stored on the provider device (76) to derive an incentive rate. This incentive rate is applied to the transaction amount to derive the incentive amount. The incentive amount is stored on the customer-carried device (74). To redeem the incentive credits stored on the customer-carried device (74), the customer enters into a second transaction with the same provider or another participating provider.  A second transaction amount is derived from this transaction and the customer may choose to redeem some or all of the incentive credits stored on the customer-carried device (74) to lower the transaction amount. When incentive credits are redeemed, they are subtracted from the incentive amount on the customer-carried device (74).  By using a customer-carried device (74), transactions may be conducted off-line.  Thus, no concurrent communications linkwith a central authority is needed.

Abstract: A reagent strip for measuring glucose concentration in whole blood has reduced interference of hematocrit with the glucose measurement. When a biological fluid contacts the strip, it causes, in a reagent impregnated in the strip, a color change that is a measure of the glucose concentration in the fluid. However, the color change is also affected by the red blood cell concentration (hematocrit), thereby reducing the accuracy of the glucose measurement. The hematocrit effect is reduced by adding to the reagent an acrylic acid polymer.

Title: Multi-channel television system with viewer-selectable video and audio
Inventor: VANCELETTE PAUL D
IPC: H04N5/44
Filed: 1997-05-26
Granted: 2000-12-26
Abstract: A television viewer can select among a choice of available camera angles and audio feeds when viewing a sporting event such as a football game without changing the television channel. Audio, video and control data are transmitted in packetized data streams with control data providing a pre-assigned channel designation (e.g., channel 10 for network X). A set-top terminal receives and processes the data streams according to user-provided commands. The terminal includes software which can be downloaded via the data streams or installed locally. The control data in the data stream is used to provide an on-screen graphical display on the television that allows the user to select the audio and video which correspond to certain areas of the football stadium, for example. Optionally, the viewer may select alternative story lines in a movie or similar program. A default setting provides primary audio and video signals. Alternative audio and video signals are selected by the user and mapped to the channel designator of the primary signal so that the different camera angles and audio feeds may be seen and heard. The viewer is therefore given the opportunity to customize the programming to enhance the entertainment or educational value.

Granted: 2005-05-24
Abstract: The present invention is generally directed to high opacity cigarette wrapping papers. The wrapping paper made according to the present invention contains a mixture of a white pigment and a black pigment. The white pigment, which can be, for instance, calcium carbonate, has a median particle size of from about 0.1 microns to about 0.5 microns, and particularly from about 0.2 microns to about 0.4 microns. It has been discovered that this particular particle size range, which is equal to one-half the wavelength of visible light, greatly increases the opacity, brightness and whiteness of the paper. Small amounts of a black pigment, such as carbon, are then added to further increase the opacity without significantly decreasing the whiteness or brightness of the paper relative to conventional cigarette paper.

Title: Multicode spread spectrum communications system
Inventor: MILLIGAN PAUL R
IPC: H04B1/707
Filed: 1998-05-27
Granted: 2009-09-22
Abstract: MultiCode Spread Spectrum (MCSS) is a modulation scheme that assigns a number N of Spread Spectrum (SS) codes to an individual user where the number of chips per SS code is M. When viewed as Direct Sequence Spread Spectrum, MCSS requires up to N correlators (or equivalently up to N Matched Filters) at the receiver with a complexity of the order of NM operations. In addition, a non ideal communication channel can cause InterCode Interference (ICI), i.e. interference between the N SS codes. In this patent, we introduce three new types of MCSS. MCSS Type I allows the information in a MCSS signal to be detected using a sequence of partial corrrelations with a combined complexity of the order of M operations. MCSS Type II allows the information in a MCSS signal to be detected in a sequence of low complexity parallel operations which reduce the ICI. MCSS Type III allows the information in a MCSS signal to be detected using a filter suitable for ASIC implementation or on Digital Signal Processor, which reduces the effect of multipath. In addition to low complexity detection and reduced ICI, MCSS has the added advantage that it is spectrally efficient.

Title: Intraaortic balloon catheter with blood feed passage formed therein for assisting circulation
Inventor: SUEDA TAIJIRO
IPC: A61M60/865
Filed: 1998-05-27
Granted: 2002-08-13
Abstract: When both the IABP and the PCPS are used, they exhibit an excellent circulation assisting effect.          In this case, however, sequela such as hypoxic encephalopathy may well occur after the heart failure is remedied.  The invention provides an intraaortic balloon catheter capable of preventing such sequela.          The balloon catheter of the invention comprises a catheter main body part of which is to be inserted into an aorta, and a balloon section formed on an outer peripheral portion of the catheter main body, to be inserted into the aorta together with the main body, and to be expandible and contractible in the aorta under the control of the IABP.  An end portion of the catheter main body functions as an introductory portion of the catheter, and has a blood feed hole formed therein for introducing, into an artery such as the aortic arch, arterial blood of high oxygen concentration fed from a circulation assisting unit such as the PCPS.  The catheter main body has a blood feed passage communicating, at one end thereof, with the blood feed hole which leads to the aorta, and communicating, at the other end thereof, with a PCPS connection port.          The blood feed passage is used for sending the arterial blood of high oxygen concentration to the aorta via the blood feed hole.
