    摘要: A method and system are provided to determine fill sufficiency of a biosensor test chamber by determining capacitance of the test chamber in which an electrochemical reaction is initiated in the test chamber and an oscillating voltage of a predetermined frequency is applied to the chamber. A phase angle between a current output and the oscillating voltage from the chamber is determined and the capacitance is calculated based on a product of the current output and a sine of the phase angle divided by a product of two times pi times the frequency and the voltage.

    摘要: A medical testing device performs a test measurement on a sample from a user of the device and displays alphanumeric characters representative of the test measurement. The device includes a display screen integrated within the housing for displaying the alphanumeric characters when the device is held by the user in a first orientation. The alphanumeric characters are not discernable if the device is held by the user in a second orientation.

    摘要: A hand-held test meter for use with an analytical test strip in the determination of an analyte in a bodily fluid sample includes a housing, a clock module disposed in the housing, a micro-controller disposed in the housing, a low-distortion signal generation circuit block (“LDSGCB”) disposed in the housing, and a strip port connector configured to operationally receive the analytical test strip. The LDSGCB includes a signal summation circuit (“SSC”) sub-block, a resistance-capacitance (RC) filter, and a single operational amplifier. The clock module and micro-controller are configured to generate phase-shifted square wave signals and output the phase-shifted square wave signals to the SSC. The SSC is configured to sum the phase-shifted square wave signals to generate a resultant summed-wave signal and output the resultant summed-wave signal to the RC filter. The RC filter is configured to filter harmonics from the resultant summed-wave signal thereby creating a reduced harmonic distortion signal.

    摘要: A portable analytical test meter is designed for use with an associated analytical test strip. A test-strip-receiving module receives the analytical test strip and is electrically connected to a dummy load calibration circuit block. That block is configured to provide a dummy magnitude correction and a dummy phase correction; and a memory block is configured to store the dummy magnitude correction and the dummy phase correction. A method for calibrating a portable analytical test meter for use with an analytical test strip includes determining a dummy magnitude correction and a dummy phase correction of the portable analytical test meter using a dummy load calibration circuit block of the portable analytical test meter. The dummy magnitude correction and the dummy phase correction are stored in a memory block of the portable analytical test meter. Using the stored dummy magnitude correction and stored dummy phase correction, an analyte is determined.

    摘要: A physiological measurement system includes a biosensor providing a signal for a fluid sample. A processor determines a physiological parameter in the form of an analyte concentration using the signal from the biosensor. A network interface conveys data between the processor and a social network. The processor can transmit a query for analyte-data-request records to the social network, receive an indication of an analyte-data-request record from the social network, and transmit the determined analyte data or physiologic data to the social network in response to the indication. The processor can alternatively retrieve user credentials from a storage device, transmit the credentials and the analyte data to the social network, retrieve from the social network different-user response data corresponding to the transmission, and present an indication of the response data. Methods for processing analyte or physiologic data are also described. Various methods include transmitting credentials and the stored analyte or physiologic data to the social network.
