Inventor: BOYETTE SCOTT M
IPC: G01N21/86
Filed: 2005-01-04
Abstract: A portable system and method for measuring the concentration of multiple chemical or biological substances where an onsite analysis of such substance s is needed. The new and original handheld sensor system uses a disposable optical test element and a spectroscopic detector that measures the test element response to specific analytes through a change in light absorbance, luminescence, and other forms of light-based response. In this way, reflecti on light intensities indicative of the test element response can be used to measure the concentration of the target analytes. The sensor system is also capable of being interfaced to an information processing unit or computer so that analytical data can be manipulated or stored electronically.

Filed: 2005-05-18
Abstract: A station used as a node in a peer-to-peer communications system keeps a list of stations to which requests for resources may be sent. The list includes for each member a performance parameter. When a station receives a request for resources it selects at least one station from the list and sends a resource request message to it. The selection of the station from the list may be performed by a random or pseudo-random process such that the probability of selection of any station is a function of the stored parameter. A station receiving such a request, for resources that it can itself supply, sends a reply to the originator. When the originator receives a reply it updates the respective performance parameter: the degree of adjustment may vary according to the quality of reply received.
