Abstract: A device control register controller for a processor block Application Specific Integrated Circuit (“ASIC”) core is described. Device control register slave blocks are coupled to the device control register controller and have access to device registers for a plurality of interfaces of the processor block ASIC core. A master device interface is for coupling at least one slave device external to the processor block ASIC core to the device control register controller. A slave device interface is for coupling a master device external to the processor block ASIC core to the device control register controller.

Abstract: Command translation of burst commands is described. A slave processor local bus (“PLB”) bridge, part of a processor block core embedded in a host IC, has a data size threshold to allow access to a crossbar switch device. A master device, coupled to the slave PLB bridge, has any of a plurality of command bus widths. A burst command is issued via a command bus, having a command bus width of the plurality, from the master device for the slave PLB bridge. The burst command is converted to a native bus width of the slave processor logic block if the command bus width is not equal to the native bus width. The burst command is translated if execution of the burst command will exceed the data size threshold and passed without the translating if the execution of the burst command will not exceed the data size threshold.

Abstract: The techniques described herein allow a more efficient transmuxing operation for transferring data from a synchronous domain (e.g., SONET) to a plesiochronous (e.g., PDH) domain as compared to the prior art, in which extraction of data streams, jitter filtering and stuff bit generation are processed separately. The techniques described herein include extraction of data from the plesiochronous data stream without complete extraction of the underlying native data stream. Filtering is performed based on synchronous timing, which results in a simpler filter design.

Abstract: Presently disclosed is a process and system for assembly-based parametric modeling having a single design environment in which the parts, components, and assemblies thereof may be designed concurrently. In embodiments of the present invention, every assembly has a deterministic parametric history supporting both top-down and bottom-up assembly design methodologies. Top-down components may be built in place, reducing the user interaction required to define the attachment and movement characteristics of the assembly. Bottom-up components may be inserted into an assembly using a parametric Insert Component Feature. The process and system also provides the ability to parametrically define the shape of an assembly in multiple orientations that still regenerate deterministically.

Abstract: A method and apparatus that allows the user of a computer aided design (CAD) system to connect three-dimensional parts to create a three-dimensional assembly using connections that completely define the attachment between the parts attached to each other by that connection. The user can simultaneously define the orientations of the parts and their behavior. “Behavior” includes whether parts are rigidly connected or allowed to move relative to one and other, and if allowed to move, the nature and limits on that movement. Within any movement allowed, the user may specify key discrete orientations known to be important to the function of the assembly, such as orientations that limit movement within the assembly. The connection method creates a smaller, more consistent representation of the underlying constraints of the assembly, improving the reliability, performance, and ease of use of a CAD system in which it is used.

Abstract: We disclose a new method of preparing liquid crystal alignment layers that can produce controllable pretilt angles from near 0 to near 90°.

Abstract: A magnetic screening system uses directional gradiometers with high resolution and accuracy to measure magnetic field signatures of target objects (e.g., gun, knife, cell phone, keys) in a volume of interest. The measured signatures can be compared to signatures of known objects stored in a local database. Various mathematical processes may be used to identify or classify target object signatures. The magnetic screening system can operate in multiple modes, such as a tracking mode, measurement mode, calibration mode, and self-test mode. Calibration may be performed in substantially continous manner to allow calibration parameters to be adjusted during system operation (e.g., tracking mode) to compensate for changes in conditions that may impact calibration parameters. Through use of unique processes and designs, the magnetic screening system can achieve a high rate of processing persons for target objects.

Abstract: A magnetic screening system uses directional gradiometers with high resolution and accuracy to measure magnetic field signatures of target objects (e.g., gun, knife, cell phone, keys) in a volume of interest. The measured signatures can be compared to signatures of known objects stored in a local database. Various mathematical processes may be used to identify or classify target object signatures. In a network of magnetic screening systems, the magnetic screening systems can transmit signatures to a central signature database, and a management computer can share the central signature database with all of the magnetic screening systems on the network. The magnetic screening system can operate in multiple modes, such as a tracking mode, measurement mode, and self-test mode. Through use of unique processes and designs, the magnetic screening system can achieve a high rate of processing persons for target objects.

Abstract: A tapered microchannel structure allows individual cells to be reacted with a continuum of concentrations or dosages of an analyte or drug from one sample. A dual sandbag structure that divides up a tapered micro channel into thirds permits performing two simultaneous tests on two different sets of cells isolated in the two sandbags by introducing a single analyte or drug into the region between the two sandbag structures.

Abstract: Automatically generating components of an object modeled in a three-dimensional modeling space by a computer aided design system includes positioning a plane in the three-dimensional modeling space to (i) logically subdivide the modeling space into a first division that includes an existing component and a second division in which a reproduction of the existing component is to be located and (ii) to define a reference geometry for creation of the reproduction of the existing component. A number of geometrically transformed components are computed by applying a series of different transformations to the existing component such that each transformed component has a different orientation. A reproduction of the existing component is constructed such that the existing component and the reproduction are symmetrical to each other with respect to the plane.
