IPC: G09F3/20
Filed: 1998-09-30
Abstract: In the novelties and collectibles industry it is known that the value of a collectable or novelty item is dependent on the condition of the said item and its component parts at the time of valuation. In this invention the intent is to offer protection to the tag or label which is secured to the novelty item by the manufacturer of the said item. A protective case has been created in order to envelope and encase the tag or label while permitting it to remain fastened to the particular novelty or collectible item. Using clear plastic molded to the shape of tag or label, the invention permits the clear viewing of the tag and its inscriptions while ensuring that it can be preserved in its pristine condition. The casing permits for the fastening agent which secures the tag or label to the item to remains secured without impeding its function.  The protective case is manufactured to specification to ensure that it fits to form for any tag or label for which protection is required. The case is manufactured using clear rigid Polyvinyl Chloride plastic formed by injection molding in such a way as to ensure that it encases the tag or label and is self fastening to remain securely closed.

Title: Surgical instrument for forming a knot
Inventor: QURESHI SALEEM URREHMAN
IPC: A61B17/34
Filed: 1998-10-07
Abstract: A surgical instrument for forming a fully tied knot to fasten bodily tissue is disclosed. The instrument has a handle assembly for actuating first and second actuators.  The first actuator remotely effects movement of a grasping jaw from an open position to a closed position relative to a suture cartridge contained in a cartridge carrier at the distal end of the instrument. Accordingly, the first actuator is capable of causing the manipulation of bodily tissue or suture filament contained in the suture cartridge. The second actuator is operatively connected to the suture filament in the suture cartridge. A portion of the suture filament is configured into a partially tied knot, and when the second actuator is actuated, it causes the proximal end of the filament to be pulled for converting the partially tied knot into a fully formed knot. Consequently, the instrument is particularly desirable during endoscopic surgery where the bodily tissue and the suture filament need to be manipulated remotely, and the conversion of the partially tied knot into the fully formed knot must also be carried out remotely to fasten the targeted tissue.

Inventor: NEWELL TERRY E
IPC: G06F11/16
Filed: 1998-10-22
Abstract: A multi-processor, shared memory computing system is disclosed. The system comprises a plurality of processing element modules, input/output processor modules and shared memory modules interconnected with the processing elements and input/output processors. The modules are interconnected by point to multi-point communication links. Each module has one transmit port and a plurality of receive ports interconnected through the links with transmit ports of other modules. Shared memory is updated and read by exchanging frames forming memory access transactions over these links. Between frames, idle codes are broadcast across the links. In response to locally sensing a failure at a module, a failed module modifies its idle code to reflect the failure. Interconnected modules lock-out a failed module in response to sensing an inhibit-on idle code at the receive ports. This facilitates the isolation and containment of faulty modules.

Title: Method for volume production of optical grating devices with tuning capability
Inventor: HATAMI-HANZA HAMID
IPC: G02B6/124
Filed: 1999-01-20
Abstract: The present invention provides a method of fabricating grating on the designated areas of optical waveguide devices that contain photo-refractive material in at least one of the core and cladding regions. The said optical waveguides are fabricated or embedded on a sample substrate by one of the associated suitable methods. Using the first mask, having openings corresponding to areas allocated for writing gratings on the waveguide circuit, and conventional lithography, the said waveguide circuit is covered by a masking material , such as chromium or any other suitable material, exempt those areas allocated for writing gratings by the exposure to a particular electromagnetic radiation spectrum for which the waveguide is photo-refractive in at least one of the core or cladding areas. Alignment markers are also transferred onto the sample at this stage. Then we fabricate the phase mask, which is a copy of the said first mask except that it is containing the phase gratings on the open areas of the first mask. Then we place strips of a soft gasket with a desired thickness on the side edges of the patterned sample and then place and attach the said phase mask over the sample by means of clips or the like so as to allow a desired distance between the phase mask and the sample. Using a mask aligner and by aligning the markers on the sample and the phase mask we make sure the phase gratings are exactly placed on the designated areas for writing gratings. The sample with the phase mask attached over it is then exposed to the said particular electromagnetic radiation for a certain time to create a grating on the designated areas. After imprinting the grating on the designated areas the said phase mask is removed for later use. Final adjustment of the grating device is done at the latest stage of manufacturing or by the consumer by further exposure to an attenuated electromagnetic radiation to tune the average refractive index alteration on the desired areas and achieve the desired wavelength response from the waveguide circuit by monitoring the wavelength response. Since in this method the phase mask is attached to the sample, writing grating can be done under less constrained conditions in terms of vibration and the quality of electromagnetic radiation used for imprinting the grating. Several gratings can be fabricated over the waveguide circuit at the same time without a need for precise mechanical motions. Long fiber grating also can be fabricated by the same principle by embedding fibers in a planar base.
