Abstract: A file system for managing data files for access by a plurality of users of a data processing system that includes internal storage for buffering, external storage, and a file user interface by which the plurality of users request access to data files. A first level, coupled to the file user interface in the internal storage allocates the internal storage for temporary storage of data to be accessed by the plurality of users, and generates requests for transactions with external storage in support of such allocations. A second level is coupled to the first level and the external storage and responds to the request for transactions with the external storage for managing the transactions for storage of data to, and retrieval of data from, the external storage. The second level defines a plurality of physical storage classes which are characterized by pre-specified parameters that allocate data files subject of transactions to locations in external memory. In response to requests for transactions, the second level identifies one of the plurality of storage classes assigned to the data file subject of the transaction and carries out the transaction with the appropriate locations in external memory. At least one of the plurality of storage classes provides for utilization of a plurality of access paths in parallel for transactions involving data files assigned to such storage class. Further, at least one parameter pre-specified for storage classes identifies a level of reliability desired for the subject data files.

Abstract: The invention relates to an encipher algorithm on the basis of a secret key, in which use is made of a substitution function, S(n,k), known as S-box, with which a series of n symbols (for example bits) can be replaced by a series of k symbols. On the basis of the secret key, an arbitrary S-box is always generated in order to avoid the use of preselected S-boxes. Such a generation can generally take place in such a way that the substitution result almost certainly does have non-linearity, but not, that it moreover has good statistical properties. These properties will be obtained, either dynamically (figure 1), if the bits of a temporary substitution result (contents of register 3) are moreover combined, via a modulo-2 adder 5, with the bits of a series with a good statistical distribution (contents of register 4) to the proper substitution result (contents of register 6), or statically (figure 2), if a series of n bits (contents of register 2 min ) to be substituted is combined with the k bits of a series with a good statistical distribution (contents of register 4 min ) to a series of n + k bits, which is subsequently substituted by means of a substitution function S{n+k,k} of S-box 1 min . The advantages are that a preselection of S-boxes with good statistical and non-linear properties can be dispensed with, and that the S-boxes always change and consequently are not known, which will benefit the strength of the encipher algorithm.

Abstract: A system and method is provided for implanting tooth analogues in the jawbone resulting in aesthetically and functionally desirable gingival tissue contours after restoration. The system permits modification and adaptation of the tooth analogue to meet intraoral demands in a manner similar to that used in the preparation and restoration of natural teeth. The system comprises a standard fixture (12) and cover screw passed through opened gingival tissue and implanted in the jawbone. After the ossointegration of the fixture, the gingiva is reopened, the cover screw removed and a healing cap (30) having a predetermined contour, is attached to the fixture. The reopened gingiva re-heals in a shape determined by the contour of the healing cap. The healing cap is then removed and replaced by an abutment (4,6,9) having an emergence profile matching that of the healing cap. An immediate snug fit between the gingival tissues and the abutment is thereby provided at the time of connection of the abutment to the fixture. A crown (2) is removably attached to the abutment by a screw (90) extending through the side of the crown into the abutment. An improved version of the healing cap is a healing cap created in two portions (138,140) so that one portion (138) around which gingiva tissue regrows remains in the patient and only a second upper portion is removed (140), and an improved abutment (204) which is engagable with the portion of the healing cap left in the patient is used for the abutment about which the crown is removably attached.

Abstract: Shaped parts are formed from a powder having the desired chemistry of the finished part by mixing the powder with a thermosetting condensation resin that acts as a binder. The resin may be partially catalyzed, or additives or surfactants added to improve rheology, mixing properties, or processing time. Upon heating, the inherently low viscosity mixture will solidify without pressure being applied to it. A rigid form is produced which is capable of being ejected from a mold. Pre-sintered shapes or parts are made by injection molding, by using semi-permanent tooling, or by prototyping. Binder removal is accomplished by thermal means and without a separate debinding step, despite the known heat resistance of thermosetting resins. Removal is due to the film forming characteristic of the binder leaving open the part's pores, by providing oxidizing conditions within the part's pores as the part is heated, and by insuring that the evolving resin vapor diffuses through the pores by heating the part in a vacuum.

Abstract: An injection molding system having at least one insulation gate seal (12) extending outwardly to bridge an insulative air space (34) between a heated nozzle (10) and the adjacent cooled cavity plate (22). Each seal (12) has a central bore (36) therethrough to convey pressurized melt from the nozzle to the aligned gate (42). The outer end of each seal has a circular groove (100) extending between a central portion (98) and a surrounding flange portion (102).

Abstract: An invention, which is fabricated using a Bipolar and Complementary Metal Oxide Semiconductor (BICMOS) technology which offers both bipolar and CMOS devices on the same silicon substrate is disclosed. The major part of the internal circuitry uses bipolar devices while the output circuit driving the transducer (16) at the output uses CMOS inverters. A voltage regulator (20) which is fed from the battery lines (VU,GND) is used to power the majority of the internal circuitry leaving only the CMOS output driver and part of a level converter to be powered directly from the battery lines. This architecture guarantees that no signal is fed back to the previous stages of the hearing aid system through the battery lines, ensuring stable operation for an extended range of the battery internal impedance value. The bipolar front-end blocks of the circuit are designed using low-voltage bipolar design techniques to operate at the 1 volt level produced by the internal voltage regulator. The voltage regulator employs a bipolar base-emitter voltage reference, which ensures the tracking of its output voltage with the headroom requirements of the bipolar circuitry over the temperature and process variations. <IMAGE>
