Title: System and method for efficiently transferring datastreams in a multimedia system
Inventor: WYLLIE JAMES C
IPC: H04N7/173
Filed: 1997-11-27
Abstract: A general purpose interface is provided to a file system of a multimedia server for improving datastream throughput by avoiding data copying and context switching. The file system includes an export registration service providing function pointers to the file system's implementation of a predefined set of zero copy interfaces. These interfaces include an initialization service to set up necessary data structures and to place use counts on objects to prevent them from being removed while zero copy operations are in progress. A termination service in the zero copy interfaces cleans up data structures and removes use counts. Additional services validate that a specified file is suitable for zero copy operations, find and record file attributes needed to later acquire buffers at interrupt level. A data structure is defined to hold these attributes for subsequent calls. Another service locks a buffer at an interrupt level and returns the amount of data present, and provides addressability to the buffer in another address space context. A data structure holds these buffer attributes for subsequent calls. A service is additionally provided to unlock the buffer at interrupt level. Finally, a service provides information on changes to the access pattern of the file such as would be needed to support VCR functions. A hash chain employing a singly linked list updated atomically allows for safe buffer lookups at interrupt level. Compare-and-swap locking facilitates this. A mailbox interface useful at interrupt level provides prefetch and release information to the daemon. In case of a lock collision or where the buffer is not available, the buffer is acquired in a process context.

Title: Nonwoven and film corrugated laminates
Inventor: SCHMIDT RICHARD JOHN
IPC: B32B37/14
Filed: 1996-06-21
Abstract: The present invention is directed to corrugated laminates with density differentials created in at least one of the layers of the laminate. The laminates (10) include a first layer (12) bonded to a second layer (14) to form a composite which has a plurality of corrugations forming a series of peaks separated by a series of valleys. At least the second layer is formed from a compressible material such as a fibrous nonwoven web which has formed therein areas of different density due to the formation process used to form the laminate. In one process the first and second layers are bonded to one another along a series of generally parallel bond lines (16) while at least one of the materials is in a tensioned state. Once bonding is completed, the tension is released and the laminate forms a series of corrugations. In the valley areas (18) immediately adjacent the bond lines the laminate and in particular the second layer has an increased density due to the bonding process. In the peak areas (20), which are between the valley areas, the laminate and in particuar the second layer has a lower density. As a result, fluids entering the laminate through the first layer tend to be drawn toward the more dense areas adjacent the bond lines. This couples with the reduced surface contact area of the first layer due to the corrugations, tend to make the material particularly well-suited for use as a body side liner for personal care absorbent articles.

Filed: 1998-02-20
Abstract: A wheeled chair is provided which permits patients to propel themselves with their feet while seated in the chair, and which is also capable of being used by patients of a wide range of heights. Accordingly, the present invention provides a wheeled chair having frame members, seating members, rolling means, and means to cause vertical adjustment of the seating member. In one embodiment, the seating member has means to allow it to be tilted. In this respect, the seating member is pivotally coupled to the frame members. In another aspect, such point of pivotal coupling is located proximate to the front portion of the seating member, thereby causing relatively less upward movement of the front portion of the seating member when the seating member is tilted than where such point of pivotal coupling is located rearward of the seating member. In a further embodiment, the frame members include vertically extendible arm rest members for supporting the arms of a person sitting in the chair.  According to a further aspect, the arm rest members may be adjusted in co-operation with the vertical adjustment of the seating member so that the person's arms may be comfortably supported in the same vertically spaced relationship to the seating member regardless of the vertical position of the seating member relative to the floor.

Title: Genetic induction of receptors for targeted radiotherapy
Inventor: CURIEL DAVID
IPC: A61K35/76
Filed: 1996-10-30
Abstract: The present invention provides a method to achieve radioisotopic localization at tumor sites, i.e., a method of enhancing radiolabeled ligand localization to a tumor in an individual in need of such treatment, comprising the steps of: transducing said tumor with a gene encoding a membrane expressed protein unique to said tumor; and administering to said individual a radiolabeled ligand which specifically binds to said protein. The use of gene therapy technology to induce expression of high affinity membrane molecules/receptors can enhance the specificity of radioisotope localization while the use of radioactive isotopes with the ability to deliver radiation damage across several cell diameters will compensate for less than perfect transduction efficiency.
