Abstract: A room temperature trap for the purification and concentration of gaseous methane. The trap utilizes the adsorption and desorption properties of microporous spherical carbon molecular sieves to purify and concentrate radiolabelled methane for application in an automated synthesis module without the need for cryogenic cooling.

Abstract: Macro- and microfluidic devices and related technologies, and chemical processes using such devices. More specifically, the devices may be used for a fully automated synthesis of radioactive compounds for imaging, such as by positron emission tomography (PET), in an efficient, compact and safe to the operator manner. In particular, embodiments of the present invention relate to an automated, multi-run, microfluidic instrument for the multi-step synthesis of radiopharmaceuticals, such as PET probes, comprising a remote shielded mini-cell containing radiation-handing components.

Abstract: A shield for absorbing radiation emitted during generation of a radioisotope. The shield includes an inner portion fabricated from a first type of shielding material. The shield also includes an outer portion fabricated from a second type of shielding material wherein the outer portion serves as a mold for forming the inner portion. The inner portion may be fabricated from a material which shields against gamma rays such as concrete. The outer portion may be fabricated from a material which moderates neutrons such as high density polyethylene. Additional shielding materials may be embedded into the inner portion as desired.

Abstract: A data storage cartridge for a data storage disk drive has a marker including a latent illuminance material such as phosphor. A matte material on the cartridge or within the marker diffusely reflects charging light that is not absorbed by the latent illuminance material in the marker. This reduces noise and signal pollution in the light then emitted by the latent illuminance material. Accordingly, an accurate decay time can be determined. The decay time is checked to provide identification of different types or generations of data storage cartridges or provides a secure keying mechanism for authorized access to proprietary software.

Abstract: The validity or authenticity of a latent illuminance material is established by heating or cooling the material to a predetermined temperature and then determining its decay time constant at that temperature. If the decay time constant is substantially equal to a predetermined value it is determined that the material is authentic. Thus, the authenticity of a material is determined by temporarily changing its decay time constant by way of temporarily changing the material's temperature using a heater or refrigerator. A light source illuminates the marker and the marker emits illuminance as phosphorescence. A photosensor detects the emitted illuminance, and the decay time constant is determined.

Abstract: A system and method which is used to identify and discriminate the type of data storage cartridge that has been inserted into a disk drive. A system for identifying a type of data storage cartridge having a marker comprises a light source for emitting light to illuminate the marker, a first photodetector for measuring a first intensity of light received from the marker, a second photodetector for measuring a second intensity of light received from the marker; and a microprocessor for determining the type of data storage cartridge responsive to said first intensity and said second intensity. The determination is made responsive to a comparison of the first and second intensities. An optical detection mechanism is provided so that it can be ascertained with near certainty that an inserted object is an appropriate disk cartridge of a certain type or generation. Sensor comparison (e.g.

Abstract: A data storage cartridge for a data storage disk drive has a latent illuminance marker. A reflective surface on the cartridge increases the intensity of the irradiance on the marker and illuminance from the marker. A light source illuminates the marker and the marker emits phosphorescence. A photosensor detects the emitted illuminance, and the decay time is determined. The decay time is checked to provide identification of different types or generations of data storage cartridges or provides a secure keying mechanism for authorized access to proprietary software.

Abstract: A system and method for applying a thick layer of luminescent emissive material, such as phosphor, to a substrate, such as a data storage cartridge, is provided whereby a luminescent emissive material is mixed with a binder, the mixture is dispensed onto a mesh screen placed over a substrate, and the mixture is then pushed through the mesh screen and applied to the substrate at a predetermined thickness. The predetermined thickness of the deposited phosphor layer is preferably between about 8 and 12 mils.

Abstract: Real time data summaries from a common data base are produced within a network. A line document program is stored within the network enabling selective visual analysis and displays of the data when the data when the data summaries are downloaded at computer terminals at a plurality of sites.
