摘要:
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.
摘要:
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.

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.

A data storage cartridge for a data storage disk drive has a latent illuminance marker. A light source illuminates the marker and the marker emits illuminance as 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.
摘要:
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., subtraction or division) is used to distinguish between objects that return light directionally to its source and objects that return light diffusely.
