US Patent:

7254828, Aug 7, 2007

Filed:

Jun 5, 2001

Appl. No.:

09/874842

Inventors:

David R. Hunter - Indianapolis IN, US

Assignee:

Acterna LLC - Germantown MD

International Classification:

H04N 7/173
H04B 1/00
H04B 7/00
H04B 15/00
G06F 15/00
H03F 1/26

US Classification:

725125, 455 631, 455501, 702191

Abstract:

A multiple input data receiver for bi-directional cable television (CATV) systems simultaneously monitors and selectively receives a return path signal on a plurality of return paths. When an appropriate data or signal transmission is detected on a return path, the corresponding return path is selected and then demodulated. The demodulated signal is appropriately decoded to yield signal data. Various tests and analyzing may be performed on the signal data. Simultaneous monitoring/receiving of all or a plurality of return paths minimizes system response time.

Appl. No.:

10/497137

International Classification:

A61M 5/00

US Classification:

604246, 604 61, 251 4

Abstract:

A dialysis valve includes a tube attached between an artery and a vein which, when elongated, simultaneously narrows in diameter at at least one location. The narrowed portion of the tube decreases the volume and velocity between the arterial and venous side of the patient to prevent damage or intimal hyperplasia on the venous side between dialysis treatments. When the valve is opened for dialysis, an unrestricted blood flow exists between the arterial and venous side, permitting a controlled, open blood flow during dialysis.
