Abstract: Disclosed is an assay device which comprises a liquid sample addition zone, a reagent zone, a detection zone, and a wicking zone, all defining a fluid flow path. The device further comprises a reagent addition zone along and in fluid communication with the fluid flow path downstream of the sample addition zone and upstream of the detection zone. An interrupting wash is added at this reagent addition zone in accordance with the method of the subject invention to control sample volume. The interrupting wash fluid is added at a predetermined fill volume on the chip device and also serves to wash the detection channel and fill the remaining chip volume.

Abstract: A temperature sensor includes a platinum member having a base portion and a plurality of prongs extending from the base portion. The platinum member is positioned within a housing that includes a first platform having a first support surface supporting the base portion, and a second platform having a second support surface spaced apart from the first support surface. The second support surface supports an end portion of at least one prong of the plurality of prongs, and medial portions of the plurality of prongs between the first and second support surfaces are suspended at a distance from an interior surface of the housing. In some cases, the housing further includes one or more support members between the first and second platforms that project from the interior surface of the housing toward the medial portion of one or more prongs to limit an amount of bending of the prongs.

Abstract: A dynamic system for generating electricity from a changing magnetic field includes solenoids routed on a single iron core, switches, and diodes. A first solenoid and a second solenoid are stationary electromagnet coils opposably routed on the iron core. A third solenoid is a stationary electric current induction coil. The first and second solenoids induce opposing magnetic fields on receiving an initial magnetizing current from a solar cell. One of the switches includes a switching system that alternately connects at least one switching node, for example, via one or more pivot joints, to one of at least two contact nodes to form a closed electric system with the first solenoid or the second solenoid, the solar cell, and a load and to change the induced magnetic field in the first solenoid or the second solenoid. The changing magnetic field induces an electric current in the third solenoid.
