The present invention provides a novel system and method that permits a "mask" to be directly incorporated into an image during image processing. This is accomplished by processing binary images or image data which are encoded using two bits rather than the usual one. The second bit is defined to be a "mask enable", which directs a processor to pass the original data through to the output image regardless of the processing result for that pixel. The present invention also provides a means of automatically providing background data to the processor for pixels outside the original image so that the result image is always the same size as the original image. For binary images, the background may be defined to have a value of "0" or "1", and this value is provided to the processing engine in place of all of the pixels which lie outside the original image. For gray-scale images, the minimum or maximum possible value is provided to the processing engine in place of all of the pixels which lie outside of the original image, effectively eliminating these values from consideration when the minimum or maximum of the neighborhood pixels is computed. The determination of whether a pixel is outside of the original image is implemented using the framing signals provided by a data flow controller along with the image data.

A data extraction processor receives data, such as image data, at a high rate of speed and generates processed results, generally at a much lower overall data rate. This sort of processing is particularly useful for machine vision image data, because it can reduce a large image data set to a much smaller data set that is more immediately useful for the currently running application. The data extraction processor may include a segmentation processor, a gradient processor, or other similar types of data extraction processors. The disclosed data extraction processor includes a data flow controller which provides image data to the processors and receives the results from the processors. The data flow controller includes at least one FIFO (first-in, first-out) memory, which allows for the provision of data to the data extraction processor and the receipt of result data therefrom to occur at different rates. Since data extraction algorithms usually generate much less data that they receive, the data flow controller stalls the flow of output data while the analysis proceeds through the data.

Disclosed are hemodialysis and similar dialysis systems including fluid flow circuits. Hemodialysis systems may include a blood flow path, and a dialysate flow path including balancing, mixing, and/or a directing circuits. Preparation of dialysate may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit and/or the various fluid flow paths may be isolated from electrical components. A gas supply may be provided that, when activated, is able to urge dialysate through the dialyzer and blood back to the patient. Such a system may be useful during a power failure. The hemodialysis system may also include fluid handling devices, such as pumps, valves, mixers, etc., actuated using a control fluid. The control fluid may be delivered to the fluid handling devices using a detachable external pump. The fluid handling devices may have a spheroid shape with a diaphragm dividing it into two compartments.

Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysate preparation may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit fluid flow paths may be isolated from electrical components. A gas supply in fluid communication with the dialysate flow path and/or the dialyzer able to urge dialysate through the dialyzer and urge blood back to the patient may be included for certain emergency situations. Fluid handling devices, such as pumps, valves, and mixers that can be actuated using a control fluid, may be included. Control fluid may be delivered by an external pump or other device, which may be detachable and/or generally rigid, optionally with a diaphragm dividing the device into first and second compartments.

A flexible, reconfigurable processing system architecture allows for the implementation of a variety of processing system configurations to be implemented on a single device, which is preferably a PCI bus add-in extension board with an attached daughter card attached and electrically connected thereto through a PCI Mezzanine type connector, and which is plugged into a personal computer PCI expansion slot. The architecture uses the PCI bus, for example, as the local CPU bus for an embedded processor, which not only allows for flexibility in system configuration but also allows PCI devices to be hidden from the host CPU to allow for proper system startup. The architecture further permits an embedded processing CPU to be re-booted when the secondary PCI bus host bus bridge fails to respond without affecting host CPU or other secondary PCI bus peripheral devices. The architecture provides a method of loading an embedded system CPU's local memory with operating system and diagnostic code without the use of ROM or FLASH memory. A system and method of reserving memory is also disclosed which utilizes a dummy or surrogate board with little of no functionality but which has a class code of a common device such as an Ethernet card.

A reagent supply arrangement for a hemodialysis system may include an E-prong connector having three parallel prongs with two outer prongs arranged in a common plane and a center prong arranged above the common plane, a first supply line for a first reagent connected in fluid communication with one of the outer prongs, a second supply line for a second reagent connected in fluid communication with the other of the outer prongs, a liquid line connected in fluid communication with the center prong, and a container for housing the first reagent having an inlet connected to the liquid line and an outlet connected to the first supply line for the first reagent. The E-prong connector may help prevent the improper connection to the dialysis unit, e. g. , because the prong arrangement ensures connection in only one way to the dialysis unit.
