Patent number: 10488359Abstract: A test meter for receiving a test strip comprises: (a) a housing; (b) electronic circuitry disposed within the housing and (c) a strip port connector connected to the electronic circuitry and extending to an opening in the housing, said strip port connector connecting the electronic circuitry with a received test strip. The strip port connector contains a pair of top and bottom contacts, said top and bottom contacts having a proximal end and a distal end and a central contact portion, the top and bottom contacts of the pair are transversely aligned with one another; and the distal ends of the top and bottom contacts are separated or separable from one another by insertion of a test strip between the opposed contacts. The contacts and the meter are adapted to permit detection of faulty contacts and/or coding associated with an inserted test strip.Type: GrantFiled: September 30, 2015Date of Patent: November 26, 2019Assignee: AgaMatrix, Inc.Inventors: Sridhar Iyengar, Charles Boiteau, Martin Forest, Colin Butters

Patent number: 10288577Abstract: A test strip with an incorporated optical waveguide and deflectors punched through the optical waveguide allows light to exit through a layer of the test strip and be detected by a photo detector. Using light and a photodetector, these uniquely coded strips are identified. The waveguide can be constructed by sandwiching two layers of the test strip around a light transmissible layer. This configuration allows light to be transmitted through the test strip and out the other end, as well as allowing some light to escape the deflector. This light is detected by a photodetector mounted in the analyte test meter. The deflectors may be placed in patterns such that detection of this light indicates certain characteristics of the strip, such as non-counterfeit, regional identification, type of analyte tested, and coding information.Type: GrantFiled: April 3, 2017Date of Patent: May 14, 2019Assignee: AgaMatrix, Inc.Inventors: Sridhar Iyengar, Ian Harding, Charles Boiteau, Colin Butters
