Abstract: A method for selecting cells and/or part(s) of a cell(s) based on at least one characteristic in an EWOD or oEWOD device is provided. The method comprising: i. providing a test panel of microdroplets, comprising at least a medium or a medium and at least one cell; ii. providing at least one reporter panel of microdroplets, containing one or more reporter entities; iii. merging microdroplets of the test panel with microdroplets of the at least one reporter panel to form a panel of merged assay microdroplets; and iv. monitoring the panel of assay microdroplets using a detection system capable of detecting a change in said reporter entity based upon the presence of at least one characteristic, and v.

Abstract: A load indicator for use with a railway car hand brake that is connected to a railway car brake rigging comprising a housing, a plurality of levers pivotally mounted in the housing, each of the plurality of levers having a first end and an opposite second end, a plate coupled to each of the plurality of lever second ends, wherein the plate is moveable with respect to the housing, and a plurality of springs each operatively coupled between a respective one of the plurality of lever first ends and the housing. At least one of the plurality of lever first ends is moveable between a first position in which tension exerted on the plate from the railway car hand brake is within a predetermined range, and a second position in which tension exerted on the load indicator from the railway car brake rigging is outside the predetermined range.

Abstract: A method for reducing the PAR of a composite carrier includes obtaining the in-phase and quadrature components for each of the carriers in the composite carrier, computing vector magnitudes corresponding to each carrier, then adding the vector magnitudes and comparing the resulting sum to a threshold. If the sum exceeds the threshold, at least of the one of the carriers are attenuated, thereby reducing the PAR of the composite carrier. In one embodiment, only the carrier or carriers having significantly larger vectors are attenuated. The pre-calculation and the subsequent attenuation process allows the composite carrier PAR to be reduced to avoid peak regrowth when the carriers are ultimately combined and transmitted.
