Abstract: An intelligent framework is provided that is disposed between a high-level language environment and a database system environment. According to one embodiment, the framework programmatically receives information regarding definitions of data structures of objects participating in a software application and information regarding relationships among the objects. Based upon the particular request from the high-level language environment and upon the definitions and relationships, the framework programmatically and dynamically generates appropriate statements associated with the database system environment that accomplish the request. For example, the framework may issue statements to define the structure of a database, access information from the database, and/or manipulate information within the database.

Abstract: A conveyor system (10) is disclosed comprised of a plurality of vehicles (12), propelled about a guide track (14) by a D.C. motor (54) and battery (52), featuring an on-board control (40) in which signals from fore and aft and side mounted photosensors (32,34,36,38) are processed by a microprocessor (42), to generate control signals for pulse width modulated control of the power to the D.C. motor (54). The control signals are applied to a motor driver circuit (50), including an H-bridge of MOSFET switching components (Q1,Q2 A ramping or progressive variation of the power applied to the motor (54) is carried out to provide gradual acceleration or deceleration, and the fore and aft photo-detectors (32,34) are triggered by the approach of another vehicle (12) at a substantial distance, to accommodate the distance required for gradual deceleration when the vehicles (12) are being queued at points along the track (14).

Abstract: A set for the isolation of cryoprecipitate includes a hollow vessel with a closed first end, a second end and a longitudinal axis, and a nipple extending from and closing the second end, said nipple enclosing a volume of approximately 2 to 5 percent of the volume of the hollow vessel. In one embodiment, the vessel is formed of a semi-rigid material and the first end is closed by a cap containing a micro-porous filter for venting the vessel. In another or further embodiment, the nipple has a tapered tip portion which may be sliced off to permit extrusion of the isolated cryoprecipitate by squeezing the vessel. In a different further embodiment, the nipple has a twist-lockable connector, for attachment to a syringe or to an applicator tip. In yet another embodiment a piston mounts on the cap within the vessel for directly extruding separated cryoprecipitate from the nipple.

Abstract: A set for the isolation of cryoprecipitate includes a hollow vessel with first and second ends and a tapered body extending to a narrow sump closing the second end, said sump enclosing a volume of approximately 2 to 5 percent of the volume of the hollow vessel. A port enters the vessel in the tapered body above the sump. In one embodiment, the vessel is formed of a rigid or semi-rigid material and the first end is closed by a cap containing a micro-porous filter for venting the vessel. In another or further embodiment, the sump has a tapered tip portion which may be sliced off to permit extrusion of the isolated cryoprecipitate by squeezing the vessel. In a different embodiment, the vessel contains an inner filter column, or bag with a filter matrix, accessible via an access port. Cellular material placed in the column is frozen, thawed and centrifuged to separate out antigen-free platelet growth factor with the cryoprecipitate.
