Abstract: Methods and assays for performing a lateral flow test are disclosed. A sample is applied to a receiving portion of a lateral flow device such that the sample flows to at least a first test zone and a second test zone. First and second signals levels at the first and second test zones over an assay period are monitored. If a first analyte of interest is present in the sample, the first analyte is labelled and the presence of labelled first analyte in the sample causes one of the first and second signals levels to increase during the assay period. A change between the first and second signal levels over a period of time during the assay period is monitored. The sample can be incubated prior to application to the receiving portion to provide homogeneity to labelling and therefore a substantially linear increase of the signal level at one of the test zones and a substantially constant signal level at the other one of the test zones.

Abstract: A liquid crystal waveguide (LCW) can include actively controlled incoupling of light into a LCW, such as by using a voltage-controlled electrode to actively vary a property of an LC material arranged to affect the incoupling of light into the LCW. Actively varying light incoupling into the LCW can be used, for example, such as for calibration or compensation or to provide closed-loop feedback such as to stabilize the amount of light into the LCW while accommodating or reducing sensitivity of the LCW to variations in one or more of: input laser light incidence angle, input laser wavelength, LCW or input laser temperature, input laser optical power level, or the like. This can advantageously help improve or maximize light incoupling efficiency, which can improve performance and robustness of the LCW under actual operating conditions. The LCW can be used for, among other things, beamsteering in in-plane and out-of-plane directions.

Abstract: A transmitter for measuring a process pressure includes a pressure sensor and a temperature sensor providing an input temperature signal. A first remote pressure sensitive diaphragm couples to the transmitter by a first capillary tube filled with a fill fluid having a density as a function of fill fluid temperature. An input circuit is operably connected to at least the pressure sensor and provides an intermediate pressure signal at least roughly representative of the process pressure. A correcting circuit is coupled to the temperature sensor and to the input circuit. The correcting circuit processes the intermediate pressure signal by compensating for the fill fluid density as a function of the temperature and provides a compensated output more closely representative of the process pressure. The correction circuit further performs an initial height determination based upon a pressure measurement made while no pressure is applied to the first diaphragm.
