Abstract: A substrate is robotically picked up at a station and transported to a measuring station to measure the distance to a reference. The substrate is aligned to a robot before measurement. The measured substrate is then transported to a pharmaceutical or diagnostic powder/grain deposition station where the powder/grains are controllably deposited on the substrate to predetermined thicknesses over a plurality of powder/grain collection zones. The deposited powder/grains are then measured to determine the thickness and area covered by the deposited powder/grains at each collection zone. The substrate is then transported to a lamination station and each collection zone of powder/grains is welded to a cover substrate. The system remembers which collection zones are out of specification so that they can be later selectively discarded.

Abstract: The invention relates to an assay system for conducting elevated temperature reactions in a fluid-tight manner within a reaction chamber, the assay system comprising: (a) a first assembly comprising the reaction chamber, and (b) a second assembly for temperature control, wherein the second assembly can be positioned adjacent to the reaction chamber. More particularly, the invention relates to an assay system comprising (a) a reaction chamber having a cover formed of a deformable material and (b) a mechanism for rapidly adjusting the temperature of the reaction chamber.

Abstract: The invention provides a parallel reaction device for conducting reactions therein comprising one or more reaction flow-ways, each such reaction flow-way comprising one or more chambers connected serially by fluid exchange channels, additional fluid exchange channels connecting such reaction channels in parallel, valve means for initiating and impeding the flow of fluids through such fluid exchange channels, and means for moving the flow of fluids into and out of such chambers.

Abstract: The present invention relates to a device and a method of use for that device for the automated preparation of nucleic acid from a biological sample. The device relates to a cassette in which all chemical manipulations occur, which includes a storage/transfer strip where the prepared nucleic acid is deposited and stored without contamination. Moreover, the waste of the preparation protocol is contained in the cassette, which, upon the separation of the filled storage/transfer strip is completely sealed off from the environment. In a preferred embodiment, the inventive device can prepare nucleic acid preparations from up to 24 different biological samples at a time.

Abstract: In accordance with the present invention, a method for manufacturing a color CRT (10) having a faceplate panel (12) is disclosed. The method includes the steps of forming a photoreceptor (36) on an interior surface of a viewing faceplate (17); establishing a substantially uniform electrostatic charge on the photoreceptor (36); and exposing selected areas of the photoreceptor (36) to visible light to form a latent charge image. The process further includes the steps of developing the latent charge image on the photoreceptor (36) by depositing (212, 213, 214) thereon charged phosphor particles; monitoring the width (218) of the deposition of the charged phosphor particles; and terminating the deposition (226, 227, 228) of the charged phosphor particles when predetermined process parameters (222, 224) are satisfied. A phosphor deposition monitor (PDM) apparatus (90) for monitoring the deposition of the charged phosphor particles on the latent charge image, formed on the photoreceptor (36), also is described.
