  • Patent number: 8852514
    Abstract: An electronic device for analyzing an aqueous solution may comprise a housing, one or more measurement circuits and a control circuit all arranged inside the housing. The housing may be configured to receive a test element. The one or more measurement circuits may be configured to produce one or more corresponding sets of measurement signals relating to an aqueous solution received on the test element. The control circuit may include a memory having instructions stored therein that are executable by the control circuit to process the one or more sets of measurement signals to determine one or more corresponding characteristics of the aqueous solution.
    Type: Grant

  • Patent number: 8142722
    Abstract: An apparatus for analyzing an aqueous solution, as may be implemented with a hand-held portable electronic device (10) and test element (16). A test pad (32) of the test element responsive in color to a characteristic of an aqueous solution is interrogated by the device by measuring intensity values of an interrogating test light as reflected off of the test pad. The test pad may be supported on an opaque and non-reflective substrate (28) that cooperates with an opaque edge portion (14E) of a test element placement member (14B) and associated side walls (14W) of the device to minimize the impingement of ambient light onto the test pad during interrogation.
