Abstract: A system and method are disclosed that enable exclusive rights in generic goods to be transferred from one party to another. A party holds an exclusive right to a good through a rescindable capability. When two parties agree on a transfer of the exclusive right to the good, a goods description memorializing the agreement is created which is in synergy with the rescindable capability. The goods description includes an acquire method that is the only method that can extract rights from the rescindable capability with which it is in synergy. The object from which the generic right is being transferred sends a message to the recipient with a reference to the rescindable capability. Upon receiving the message, the recipient invokes the acquire method of the referenced goods description, which returns a new rescindable capability that encompasses the generic right just transferred. Once the recipient holds a reference to the new rescindable capability, the sender has had its rights rescinded.

Abstract: A signal communication device for use within a computer includes a set of optical fibers configured to form an optical computer bus between a set of computer sub-system elements of a computer. A set of input optical connector cards are connected to the set of optical fibers. Each of the input optical connector cards includes a transmitting dynamic bandwidth allocator responsive to an optical bus clock signal operating at a multiple of a computer system clock signal such that a set of bus time slots are available for each computer system clock signal cycle. The transmitting dynamic bandwidth allocator allows a light signal to be applied to the optical computer bus during a dynamically assigned bus time slot. In this way, the optical computer bus bandwidth can be dynamically allocated to different computer sub-system elements during a single computer system clock signal cycle.

Abstract: A mill is described for compacting agricultural fibrous matter, such as straw or other agricultural waste, into a structural board. The board is useful as a dominant part of a load bearing and insulating panel replacing many of the load bearing and insulating structures typically used to make small buildings, such as houses. The mill includes many features not found in previous mills of this type, including not only a packer to place material in front of an oscillating ram head as is known, but a precompactor arrangement to regulate the volume of material fed to the packer. Another feature incorporated into the mill to aid in achieving a consistent density is a pressure offset mechanism which adjusts the rate of core formation. The mill has a modular design to facilitate replacement of those components subjected to significant wear.

Abstract: A method and apparatus for cooling an integrated circuit device mounted face-down on a package such that the device may be optically probed. The method of the present invention includes the following steps: (1) placing an optically-transparent window over the integrated circuit device to form a channel bounded by the optically-transparent window and the integrated circuit device and (2) flowing an optically-transparent fluid through the channel to remove heat dissipated by the integrated circuit device.

Abstract: A novel apparatus and method is disclosed to assure validity of data accessed from synchronous memory during a "read" operation, wherein the synchronous memory is operating synchronously at a high frequency system clock. The invention comprises a programmable delay module which generates a skewed clock signal which is used to clock in data read from the synchronous memory. The programmable delay module generates the skewed clock signal by adding programmable time delays to the system clock signal. The inserted delay increases the data valid window time available for the "read" operation and allows sufficient setup and hold time for valid data to be read by a memory controller.

Abstract: An electronic communication authority server that provides centralized key management, implementation of role-based enterprise policies and workflow and projection of corporate authorities over trusted networks. The authority server includes a key database that associates keys, signatures and indicators of corporate authority (such as letterhead) with particular corporate roles. There can be multiple roles or a single role (e.g., employee) for each authority server. Users associated with one or more roles are permitted by the authority server to exercise authority or include the indicators of authority in their communications. The authority server also encrypts/decrypts and signs/verifies communications from/to a user using the keys and signatures associated with the role being exercised by the user for that communication. The authority server permits roles to be delegated or transferred, which facilitates the execution by the authority server of role-dependent workflow procedures.

Abstract: A method to create an improved hydrodynamic bearing which is relatively insensitive to changes in load and rotational speed is provided, wherein the hydrodynamic bearing is useful in a spindle motor for a disc drive or the like which is stiffer than known standard spindle motors so that the stability of the system and specifically of the actuator arm and transducer relative to the rotating disc is optimized. The hydrodynamic bearing can also be used as a bearing cartridge or as the cartridge that may be incorporated into a spindle motor or the like, where the bearing includes a shaft and at least two independent bearings each comprising a thrust plate supported on the shaft and a counter plate incorporated in a sleeve which is capable of relative rotation around the shaft.

Abstract: Novel memory cells utilize source-side injection, allowing very small programming currents. If desired, to-be-programmed cells are programmed simultaneously while not requiring an unacceptably large programming current for any given programming operation. In one embodiment, memory arrays are organized in sectors with each sector being formed of a single column or a group of columns having their control gates connected in common. In one embodiment, a high speed shift register is used in place of a row decoder to serially shift in data for the word lines, with all data for each word line of a sector being contained in the shift register on completion of its serial loading. In one embodiment, speed is improved by utilizing a parallel loaded buffer register which receives parallel data from the high speed shift register and holds that data during the write operation, allowing the shift register to receive serial loaded data during the write operation for use in a subsequent write operation.

Abstract: Particularly, a system and method are disclosed that enable an author of a subsection of a document quickly to locate referenced information in other parts of the document or different documents prepared by other authors and then incorporate that information in their own document. An author tags information in their document that other authors might wish to import. Each time the document is updated, or as requested by the author, the author's tags and other tags that reference information that is importable by default (e.g., section headings, figures, tables) are exported to a tag repository that is accessible to all other authors. The tag repository also holds the tags generated by other authors from different documents. Using information finding/linking programs any of the authors can search the tag repository and select tags corresponding to information they would like to import into their own documents.

Abstract: A distributed garbage collection system and method is disclosed that is compatible with local ref-count or full garbage collection and that ensures that no local object's storage is deleted by the local garbage collector unless it is certain that there are no actual or potential remote references to that local object. The disclosed system and method are implemented in the context of a transparent distributed object system in which communications between objects in different processes are enabled by dedicated proxy objects that are linked to corresponding remote objects via a pair of transport objects. Additional proxy holder objects and proxy holder proxies ensure that objects for which third-party object references are passed (i.e., where one object in a first process passes a remote object in a second process a reference to a third object in a third process) are not collected until a direct link is established between the remote object in the second process and the third object in the third object space.

Abstract: A novel B tree data structure is taught and implemented for use in conjunction with a tertiary storage system. The tertiary storage system utilizes three levels of memory hierarchy: primary memory, such as RAM; read-write secondary storage, such as disk memory; and lower speed, and less expensive mass storage, for example a CD-ROM. A novel B tree is utilized to access data stored in two or more types of memory, such as a CD-ROM memory and a disk drive memory, and adapts for the provision of updated data stored on the hard disk which either replaces or supplements data stored on the CD-ROM. The B tree includes, for each data bucket, a pointer for both a CD-ROM and a disk drive location, and are, in certain embodiments, used in conjunction with a bit mask to indicate the presence of valid data in a first one of the memories, such as CD-ROM, and, if desired, a bloom filter associated with data stored in the second memory type, such as a magnetic disk, in order to speed accesses.

Abstract: High rare-earth content glasses (Ln.sub.2 O.sub.3 .gtoreq.20 mol %) have applications as high optical density wavelength-selective filters, faraday rotators, scintillation glasses and high index glasses. New glasses are formed by adding TiO.sub.2 to the system SiO.sub.2 --B.sub.2 O.sub.3 --Al.sub.2 O.sub.3 --Ln.sub.2 O.sub.3. These glasses have improved optical properties, extended glass formation range and have superior resistance to devitrification. In some embodiments TiO.sub.2 can fully replace the Al.sub.2 O.sub.3. In additional embodiments, SiO.sub.2 can be completely removed from the glass.
