  • Patent number: 10197524
    Abstract: Methods are disclosed for scaling body fluid analysis data to correct and/or compensate for confounding variables such as hematocrit (Hct), temperature, variations in electrode conductivity or combinations thereof before providing an analyte concentration. The scaling methods utilize current response data obtained from an AC block applied prior to a DC block to minimize the impact of such confounding variables upon the observed DC current response before creating descriptors or algorithms. The scaling methods therefore compensate the measured DC current by using data from the AC block made on the same sample. Also disclosed are devices, apparatuses and systems incorporating the various scaling methods.

  • Patent number: 10119931
    Abstract: Methods are disclosed for measuring an analyte concentration in a fluidic sample. Such methods further allow one to correct and/or compensate for confounding variables such as hematocrit (Hct), temperature or both before providing an analyte concentration. The measurement methods utilize information obtained from test sequences having at least one AC block and at least one pulsed DC block, where pulsed DC block includes at least one recovery potential, and where a closed circuit condition of the electrode system is maintained during the DC block. Also disclosed are devices, apparatuses and systems incorporating the various measurement methods.

  • Patent number: 9885614
    Abstract: A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.

  • Publication number: 20170345513
    Abstract: The present disclosure relates to method and system of implementing one wire programmable circuit by using the same terminal OUT as both main circuit output terminal and the digital I/O interfacing terminal of the circuit. The present invention overcomes the shortcoming of prior arts and does not require the circuit to be powered down first and then powered up again each time the circuit is switched between interfacing mode (read/write/program OTP) and the normal output mode, therefore shorten the time of interfacing with the OTP as well as simplified the interfacing system used to read/write/program the OTP. The present invention also enables the possibility to put the no longer required system clock into sleeping mode after the OTP has been programmed, and has the advantages of reducing system power consumption as well as system noise due to the existing of digital clock.

  • Patent number: 9594045
    Abstract: Methods are disclosed for measuring an analyte concentration in a fluidic sample. Such methods further allow one to provide an error code or correct and/or compensate for interferents such as an antioxidant before providing an analyte concentration. The measurement methods utilize information obtained from test sequences having at least one DC block, such as a slow-ramped bi-polar waveform, where a closed circuit condition is maintained during the DC block. The methods use information relating to status of a redox mediator feature during the electrochemical analysis to provide an antioxidant failsafe if the antioxidant is interfering with the analyte concentration. Also disclosed are devices, apparatuses and systems incorporating the various measurement methods.

  • Patent number: 9519053
    Abstract: A distance measuring apparatus and a distance measuring method are provided. The distance measuring apparatus includes a GPS module, an ultrasound transceiver module and a control module. The GPS module is configured to generate a pulse signal. The ultrasound transceiver module is configured to generate and transmit a first ultrasound signal and receive a second ultrasound signal transmitted from an object. When the control module receives the pulse signal, the control module controls the ultrasound transceiver module to generate and transmit the first ultrasound signal, and determines whether the ultrasound transceiver module receives the second ultrasound signal within a first interval. When the ultrasound transceiver module receives the second ultrasound signal within the first interval, the control module determines a distance between the distance measuring apparatus and the object according to a time difference.
