  • Publication number: 20240094154
    Abstract: The present disclosure provides a method of fabricating a sensor assembly in which a sensor surface has an anchor species provided thereon, the anchor species having a first functional group attached. The method further comprises disposing a fluid channel over the surface and subsequently providing an analyte capture species to the fluid channel. The analyte capture species comprises a second functional group configured to react with the first functional group. The surface is then exposed to photo radiation and the first and second functional groups react forming a link between the analyte capture species and the anchor species on the sensing surface.

  • Patent number: 9621336
    Abstract: A system and a technique for recovering data from an input data stream without synchronization of an input sampling circuit to the input data stream determines a count of incoming samples (or frames) without generating a signal that is frequency-locked to the input data stream. A first clock is generated comprising a frequency that is greater than or equal to an expected frequency of the input data stream. A sample count is incremented in response to a sample received in the input data stream, and is decremented in response to a second clock signal. The second clock is generated from the first clock signal by passing the first clock signal if the sample count of the sample counter does not equal a predetermined sample count value and by blocking the first clock signal if the sample count equals the predetermined sample count value.
