Abstract: A process (20) and design tool (62) are presented for the accurate prediction of design parameters (42) for components (38) of an integrated circuit (22) during the early stages of the design of that integrated circuit (22). These predicted design parameters (42) include pin count parameters (50), propagation delay parameters (52), layout area parameters (54), dynamic power parameters (56), static power parameters (58), and total power parameters (60). With these parameters, the designer interactively modifies the design prior to the layout and prototyping of the integrated circuit (22). The dynamic power parameters (56) and total power parameters (60) may be repetitively predicted with differing input items to establish a power usage pattern for the integrated circuit (22).

Abstract: A multiple spindle bar machine is disclosed including a cylindrical spindle carrier assembly supporting a spaced apart array of spindle bearings. Workpiece holding spindles are rotatably journaled in the spindle bearings. A hollow spindle drive shaft extends through a central opening in the spindle carrier and includes a drive gear pinned to an end of the shaft. The drive gear intermeshes with spindle gears to drive the spindles at a uniform rotational speed. The spindle carrier assembly is rotatably supported by at least one set of tapered roller bearings bearing against an outer peripheral surface of a spindle carrier. The set of roller bearings are disposed in a notched annulus in an inner peripheral surface a headstock upright. Each roller bearing forms an acute included angle between the spindle carrier outer peripheral surface and a surface of the tapered bearing facing the spindle carrier. The set of tapered roller bearing is mechanically preloaded before machining operations commence.

Abstract: A sight flow indicator having a viewing window for monitoring liquid flowing therethrough is disclosed. The flow indicator is configured to disentrain gas and particulate from a portion of the fluid. The flow indicator is also configured to reduce the velocity of fluid flowing therethrough. The portion of the fluid from which gas and particulate has been disentrained is diverted from the main flow stream, past the viewing window. The relatively clean liquid sample flowing past the viewing window lends itself to relatively accurate optical analysis using, compared to the bulk fluid flowing through the flow indicator. The flow indicator is well-suited for use with a spectrometer or other optical analyzer.

Abstract: A cam buckle system has a lever arm which is pivotally connected to a base plate. The lever arm rotates a lock arm with cam teeth into abutment with a strap to lock the strap against movement. The strap also extends through a capture slot on the lever arm so that manual movement of the strap will open or lock the cam buckle as well as tension the strap. The cam buckle can be used for any tension member, but has particular utility to interconnect a pair of wrist straps of a ski pole grip. The straps and cam buckle form an adjustable length loop which can be tightened to form a heel support for the ski grip. A single point attachment at a top of the handle includes a vertical slot and spreader plate to vertically orient and open the pair of straps. This creates a wrist strap adjustment system that can be quickly manipulated using a single gloved hand.

Abstract: A projectile fuze detects transitions between target layers by an electronic antenna radiating laterally into the target material and coupled to a pullable oscillator whose frequency shifts as the target material changes while the projectile penetrates. A frequency shift threshold detector relates the observed frequency shifts to a stored target profile to detonate the projectile after the desired layer penetration.

Abstract: A scalable multiplier architecture for the Galois field GF(2k) is implemented in a programmable circuit. This architecture may be used in an implementation of public-key cryptosystems which use programmable multipliers in large Galois fields. This architecture is also fine grain scalable in both the time and the area (or logic) dimensions.

Abstract: Key escrow is achieved without a key escrow facility. An escrow key pair is generated and stored in the terminal. A key escrow field that includes a traffic key encrypted with the escrow key is provided before encrypted traffic is communicated. When access to the traffic key is authorized, the escrow key is extracted from the terminal and used to decrypt the traffic key. The private portion of the escrow key is covered in the terminal with an escrow key access number. The escrow key access number is preferably generated by the terminal manufacturer with a secret algorithm using the terminal serial number. Alternatively, the escrow key is stored within a user token, rather than the terminal.

Abstract: For simultaneous deformations of multiple surfaces, a constraint called a link constraint is created to link two faces that are to be deformed together. The link constraint consists of a relationship between a constraint curve in each face to be deformed. The selected constraint curve may be any curve, including trimmed curves and part of a boundary curve. As the faces are deformed, the link constraint limits the deformation of the faces by acting as a zipper between the two surfaces along the selected constraint curve. For local deformations within a surface, a hierarchy is created within specific areas, known as patches, of an individual face in a model, ensuring that when a patch in the hierarchy is deformed, the deformation affects patches lower in the hierarchy than that patch, but the deformation does not affect patches higher in the hierarchy.

Abstract: An apparatus is disclosed for continuous load optimization of wireless communication networks by making use of statistical data about both the communication medium characteristics and the characteristics of messages that users desire to send over the network. The network comprises a network control base station (20) and a plurality of slave stations (22). One or more applications (72, 104) are associated with each station which are used to generate the messages in digital format. Each application is coupled to a protocol stack (88) that defines the required characteristics of the data and changes to the data that occur during the communication process. An interface (90) is coupled to the layers of each protocol stack (88) to allow tuning of the message characteristics to maximize successful transmission with minimum message latency.

Abstract: An interface between a digital communication system and a PSTN establishes a user configurable secure encrypted link to a digital subscriber unit through the digital communication system, and provides clear (unencrypted) voice to telephone sets through the PSTN.

Abstract: Primary effusion lymphoma (PEL) cells harbor Kaposi's sarcoma-associated herpesvirus (KSHV) episomes and express a KSHV encoded latency-associated nuclear antigen (LANA). In PEL cells, LANA and KSHV DNA co-localized in dots in interphase nuclei and along mitotic chromosomes. In the absence of KSHV DNA, LANA was diffusely distributed in the nucleus or on mitotic chromosomes. In lymphoblasts, LANA was necessary and sufficient for the persistence of episomes containing a specific KSHV DNA fragment. Furthermore, LANA co-localized with the artificial KSHV DNA episomes in nuclei and along mitotic chromosomes. The KSHV DNA segment that provides for efficient persistence in LANA positive cells has been identified as the rhodino virus cis-acting element (RVCAE). These results support a model in which LANA tethers episomes containing the KSHV RVCAE DNA to chromosomes during mitosis to enable efficient segregation to progeny cells.
