Filed:

Apr 7, 2006

Appl. No.:

11/279044

Inventors:

Ian Harding - Somerville MA, US
Sridhar G. Iyengar - Salem NH, US
Ha Nguyen - Quincy MA, US
Richard Williams - Andover MA, US

Assignee:

AgaMatrix, Inc. - Salem NH

International Classification:

G01N 33/49

US Classification:

422 73, 20440301, 436 69

Abstract:

A device for measuring blood coagulation time is formed from a first substrate; a second substrate; a spacer layer disposed between the first and second substrates, said spacer layer having an opening formed therein defining a sample receiving chamber, a vented sink chamber, and an elongated reservoir forming a conduit for liquid movement between the sample receiving chamber and the sink chamber; a first electrode disposed on the first substrate, said first electrode being exposed in the reservoir portion through a first opening in the spacer layer; and a second electrode disposed on the second substrate, said second electrode being exposed in the reservoir portion through a second opening in the spacer layer. The device of the invention is used in combination with an apparatus that is connected to the first and second electrodes for measuring current flow between the first and second electrodes. Changes in observed current are indicative of flow through the device, and a cessation of flow indicates coagulation.

International Classification:

G06Q 40/00

US Classification:

705 37, 705 35

Abstract:

Methods and apparatuses for detecting fraudulent activities made over a network-based transaction facility using a machine. In responsive to a first event with respect to the network-based transaction facility and initiated under a first user identity from the machine which is coupled to the network-based transaction facility via a network, the method causes a first identifier associated with the first user identity to be stored on the machine. In responsive to a second event with respect to the network-based transaction facility and initiated under a second user identity from the machine, the method causes a detecting of a potentially fraudulent activity by detecting a lack of correspondence between the first identifier stored on the machine and a second identifier associated with the second user identity.
