Abstract: Information is added to an encapsulated payload in a data field of a frame subsequently to placing a checksum into a checksum field of a header encapsulating the payload, wherein the checksum has been determined from byte values of the header and the payload, yet having the checksum remaining detectable as valid upon interpretation of the header and the payload. A signature field that contains the information is inserted into the data field. The signature field has a checksum cheater subfield. A one's complement of a checksum determined from byte values of the information is then placed into the checksum cheater subfield. Accordingly, the checksum in the checksum field of the header remains valid.

Abstract: A distributed content architecture is provided the de-coupled site management and presentation from asset inventory management and publishing. An active content cell is provided which manages the inventory and publishing aspects of the information. A content management server is provided that resides at any site and that effects content commerce. The active content cell resides at a content publisher's site and is under content publisher's control. Thus, the invention enables a virtual content market in which content is controlled by the content publisher while commercial transactions are separately controlled by a content management server. Active content cells are site independent such that multiple active content cells can co-exist in one location or be geographically dispersed. Further, active content cells have a unique IP address and register the location just as any other site although their behavior is different.

Abstract: Timestamp information can be placed in a frame that includes a first portion processable at a selected layer of a protocol stack and a second portion processable at a lower protocol layer of the protocol stack subsequently to the processing of the first portion, wherein the first portion is contained within the second portion and wherein a numerically computed error detection code for the second portion is computed during processing of the second portion. A timestamp signature having a timestamp subfield of initialized data and a corrector subfield of initialized data is embedded in the first portion during processing thereof at the selected protocol layer. A numerical constant functionally equivalent to the numerically computed error detection code is determinable from the initialized data in the timestamp subfield and the corrector subfield. The data in said timestamp subfield is modified with timestamp information subsequently to processing of the second portion at the lower protocol layer.

Abstract: The presence of radiation shielding material concealing illegitimate content in a container is detected by obtaining each of measured gamma-ray data and measured neutron data from the container, and comparing the measured gamma-ray and neutron data to expected gamma-ray and neutron data. An anomaly between the measured data and the expected data is an indicum of the presence of such material shielding such illegitimate content.

Abstract: A computer program, database and method for the detection of fissile or radioactive material or radiation shielding material in a container works with detection devices brought into proximity to containers so that the presence of fissile or radioactive material, or shielding materials to conceal the presence of such fissile or radioactive materials, may be detected. A comparison may then be made of the output of the detector to a threshold to determine subsequent action regarding the shipping container. The threshold may be based on the output of known, dangerous radioactive materials, known legitimate contents or empty containers.

Abstract: A STANDARD BLOCK architecture for integrated circuit (IC) design. The STANDARD BLOCK architecture provides a new level of abstraction with a granularity and regularity that is most appropriate for the physical implementation of complex, large scale deep-submicron IC designs. To this end, the STANDARD BLOCK architecture combines the advantages of standard-cell-based and functional-block-based architectures. The STANDARD BLOCK architecture includes a STANDARD BLOCK form that is physically constrained having one fixed or quantized dimension and one variable dimension that ranges between predefined limits. The STANDARD BLOCK granularity is larger than the standard cell granularity such that each STANDARD BLOCK includes a plurality of standard cells. In the STANDARD BLOCK architecture, each STANDARD BLOCK has flexible physical design properties.

Abstract: In a block model abstraction of an integrated circuit developed from a hierarchal netlist, the hierarchal handling of timing exceptions is accomplished by selecting certain nodes not viewable at the top level in accordance with a set of rules, and raising these nodes to the top level so that defined timing exceptions may be applied. The timing model is next generated, and exception signatures created for paths between the selected nodes. Signatures are then removed from paths were such signature would not otherwise be valid.

Abstract: An integrated circuit (IC) architecture with STANDARD BLOCKs. The IC architecture forms a layout that includes a plurality of STANDARD BLOCKs, top-level cells, and hard IP blocks. The STANDARD BLOCKS form row-based or column-based STANDARD BLOCK ARRAY configurations in which STANDARD BLOCKs are placed adjacent to each other in a row or column configuration with their fixed or quantized dimension aligned and oriented perpendicular to the STANDARD BLOCK ARRAY direction. Individual STANDARD BLOCK ARRAYs can be spaced apart forming channels between them to allow for routing interconnections, or overlapping one another in a flipped configuration sharing VDD or GND power rails. The IC layout includes sites reserved for top-level cells that are placed in channels between STANDARD BLOCK ARRAYs, around the perimeter of STANDARD BLOCKs, or arranged in a staggered or diagonal configuration inside the STANDARD BLOCKs.

Abstract: Submicron boron nitride is used as a catalyst for thermally activating polysiloxane resins when uniformly mixed with the resin either using anhydrous acetone for wet mixing or simply hot melt mixing. Boron nitride is also used to coat the fibers using a particulate sizing approach. The coated fibers are used to activate the polymer resin blend. Fabric may be impregnated with the resin to mold high temperature composite laminates from which high temperature, non-metallic gaskets may be cut.

Abstract: An actuator for tilting the plane of an object includes a substrate and a pair of piezoelectric material members. Each of the piezoelectric members has a top surface, a bottom surface, a first side surface and a second side surface. The bottom surface is mounted to the substrate, and the first side surfaces of each of the members are affixed to each other and electrically connected in common. One of the piezoelectric material members further has a polarization selected so that a voltage applied between the first side surface and the second side surface thereof causes the piezoelectric material member to either contract or expand between the top surface and said bottom surface, depending on the polarity of the voltage. The object is mounted to the top surface of each of the piezoelectric material members so that when a voltage is applied to one of the piezoelectric material members, the object either tilts toward or away from that member, depending on the polarity of the voltage.

Abstract: An electromagnetically actuator is disclosed having an electromagnet, a core element, the core element having a normally biased initial spaced apart first position distal from the electromagnet when the electromagnet is off and a second stop position proximal from the electromagnet when the electromagnet is on, a first resilient member adapted to bias said core element in the normally biased first position, and a second resilient member adapted to bias the electromagnet away from the core. The first resilient member is more resilient than the second resilient member. Therefore, the core approaches the electromagnet when the electromagnet is on until the core reaches the fixed stop position, and the electromagnet subsequently approaches the core to the fixed stop position. The actuator may further include an adjustment member that engages the electromagnet so as to control the pressure of the electromagnet against the second resilient member, whereby the axial position of the electromagnet is controlled.
