Abstract: A roller guide wheel contains a single set of spherical bearings and is constructed with a precision outer race machined into the guide wheel interior and an inner race formed by the surfaces of two conically-tapered set screws that affix the roller guide wheel within a housing made part of a stage slider. The roller guide wheel, which contacts a rail on one side of the stage body and exhibits a non-nutating axis of rotation, serves as way for the translating slider. The way on the opposing side of the slider is a set of v-groove contacts that make sliding contact with a rail on the corresponding side of the stage body. A flexure is machined into the slider permitting preload of the slider contacts points with the rails. The stage geometry permits a large slider through-hole and the use of alternative way mechanisms with the roller guide wheel.

Abstract: The invention provides devices and systems, as well as associated methods of using them, that employ a remote Dicke switching element—i.e., distal to a radiometer. The devices, systems, and methods are suitable for both diagnostic and therapeutic applications in a wide variety of tissues.

Abstract: A low profile temperature transducer has a working surface for placement against a body surface and a first output. The transducer is a flat laminate composed of alternating conductive and dielectric layers. The laminate defines at least one slotline antenna for exposure to the body surface to pick up thermal emissions from the underlying tissue at depth. A feed network having a characteristic impedance is connected to the first output and a slotline-to-stripline transition is connected between the at least one antenna and the feed network, the transition providing a match between the impedance at the at least one antenna and the characteristic impedance. Also, a temperature sensor may be present at the working surface to detect the body surface temperature under the transducer, that surface temperature being used to calculate actual temperature at depth.

Abstract: The present invention relates to active delivery system formulations, and methods of making and using the same. Said formulations, when applied to a substrate surface, form a protective coating on the surface and permit constituent active agents to act on the surface and in the surrounding medium.

Abstract: A machine for making sealed liquid pouches with a free-floating straw inside the pouch is described. The machine comprises a vertical pouch former which forms a continuous plastic film tube from a film sheet with the plastic film tube disposed about a liquid dispensing spout. A straw convecting tube also extends to one side of the liquid dispensing spout inside the tube. A straw is released through the convecting tube at predetermined intervals in synchronism with a transverse sealer which forms a bottom and top edge seal of pouches as liquid is continuously dispensed through the liquid dispensing tube. The plastic film tube is maintained in a transversely expanded condition during the filling of the pouch and is advanced by an engagement mechanism between the sealing cycles.
