  • Publication number: 20230226539
    Abstract: A system for testing for an analyte includes a test strip. The test strip includes a first flow path. The test strip further includes a heating element in communication with a heating area of the first flow path, for heating a sample in the first flow path. The test strip further includes an e-gate, the e-gate in the first flow path, the e-gate separating the heating area from a detection area of the first flow path.

  • Publication number: 20060187360
    Abstract: An apparatus such as a television signal receiver provides an AGC function by using multiple feedback sources which provide both narrow band and wide band AGC signals in an adaptive manner. According to an exemplary embodiment, the apparatus includes a tuner operative to generate first and second IF signals. A first demodulator is operative to generate a first AGC signal responsive to the first IF signal. A second demodulator is operative to generate a second AGC signal responsive to the second IF signal. A wide band AGC detector is operative to generate a third AGC signal responsive to at least one of the first and second IF signals. A switch is operative to selectively provide one of the first, second and third AGC signals to the tuner responsive to a predetermined condition.

  • Publication number: 20060181651
    Abstract: An apparatus such as a television signal receiver employs an efficient and cost-effective signal processing architecture which enables, among other things, the reception and processing of both analog and digital signals from multiple signal sources, such as but not limited to, terrestrial and cable signal sources. According to an exemplary embodiment, the apparatus includes a first tuner operative to generate a first IF signal corresponding to a first RF signal. A first demodulator is operative to generate a first demodulated signal corresponding to the first IF signal. A second tuner is operative to generate a second IF signal corresponding to a second RF signal. A second demodulator is operative to generate a second demodulated signal corresponding to the second IF signal. A third demodulator is operative to generate a third demodulated signal corresponding to one of the first and second IF signals.

  • Publication number: 20050162570
    Abstract: A system, apparatus and/or method provides frequency response adjustment of an RF input filter of an RF tuner based on impedance of an antenna system that is providing reception of RF signals to the RF tuner. The frequency response adjustment is preferably accomplished dynamically and/or with respect to each frequency tuned. Particularly, the system, method and/or apparatus provides compensation at the RF tuner level for mistuning effects produced on the RF tuner by antenna system impedance presented at the antenna input that is other than a designed for impedance. Frequency response of an RF input filter for the RF tuner is electronically adjustable with an independent or semi-independent control voltage signal based on one or more measured parameters of a tuning frequency. Frequency response adjustment may include adjustment of a center frequency of the RF input filter bandpass frequency range and/or altering the bandpass frequency range of the RF input filter.
