Appl. No.:

13/461329

Inventors:

Brian K. Thibeault - Attleboro MA, US
Deborah P. Clark - Dudley MA, US

Assignee:

GENERAL INSTRUMENT CORPORATION - Horsham PA

International Classification:

H04B 17/00
H04B 1/38

US Classification:

375222

Abstract:

A method and computing device for maintaining the stability of the upstream channel quality measurements in an upstream channel bonded system. The method configures a cable modem, that communicates using bonded channels, to periodically exchange ranging messages on the bonded channels, where a bonded channel ranging interval determines a period for the exchange. The method also monitors a signal quality metric for a monitored channel of the bonded channels by periodically retrieving a quality measurement for the monitored channel, a period between each retrieval determined by a channel quality monitoring interval. The method sends an invite ranging message to the cable modem before retrieval of the quality measurement for the monitored channel, and retrieves the quality measurement for the monitored channel. The method bases the signal quality metric for the monitored channel on the quality measurement.

Abstract:

This invention encompasses methods and apparatus for collecting blood samples. It has been discovered that p-aminobenzoyldiethylaminoethanol (procaine) is unexpectedly potent in stabilizing blood samples against platelet release reactions. Methods and apparatus of this invention are particularly useful for collecting blood samples for subsequent platelet factor 4 determination.
