  • Publication number: 20130079254
    Abstract: A microfluidic dialysis device that has a first channel for receiving a biological sample, a second channel, and a series of adjacent channels extending between the first channel and the second channel. Each of the adjacent channels pin a meniscus of the sample that arrests capillary flow between the first channel and the second channel. A bypass channel between the first channel and the second channel, the bypass channel joining the second channel upstream of the adjacent channels and is configured for uninterrupted capillary driven flow from the first channel to the second channel. Flow from the bypass channel reaches the meniscus pinned at each of the adjacent channels after the meniscus has formed to sequentially remove each of the menisci and allow flow from the first channel to the second channel via the adjacent channels as well as the bypass channel.

  • Patent number: 8356885
    Abstract: A fluid sensor for detecting fluid in a chamber, has a MEMS sensing element of conductive material with a resistance that is a function of temperature, and electrical contacts for connection to an electrical power source for heating the sensing element with an electrical signal, so that control circuitry can measure the current passing through the sensing element during heating of the sensing element; and determine the temperature of the sensing element from the known applied voltage, the measured current and the known relationship between the current, resistance and temperature. As the temperature of the element will be greater if it is in the presence of gas rather than liquid, the sensor determines if there is liquid or gas in the chamber. This is particularly useful to detect if the chambers of an inkjet printhead are primed with ink.
