  • Publication number: 20060117280
    Abstract: A technique for analyzing digital circuits to identify pin swaps is provided for circuit layout and similar tasks in which the circuit is first decomposed into regions. Logic functions of the regions are decomposed into a directed graph of the logic functions. A swap structure is created in accordance with the directed graph to facilitate identification of input equivalences.

  • Publication number: 20060064737
    Abstract: To address security that can arise in information systems, the present invention uses novel methods and/or systems to enhance security in information systems, using a new way to deploy selected security policies. Instead of trying to modify a whole binary file all at once to add in code to implement additional security policies, the current invention modifies the code in memory in a piecemeal, as-needed fashion.

  • Publication number: 20060053492
    Abstract: The invention protects software on a data processor by first identifying the software, authenticating it, and then tracking it down to the memory of the processor where it executes. The invention then protects the software in the memory during execution. The invention creates a chain of protection from the origin of the software through to its use at the lowest levels of the hardware.

  • Publication number: 20050281490
    Abstract: A tamper-evident reclosable package having a header that is tack sealed to the zipper. A light tack, in the form of a light weld, is made at the end of the package header. The header is the top portion of the package and is designed to shroud the zipper. The header serves as a tamper-evident feature, and also serves to maintain cleanliness and aesthetics of the package. The header must be tom before a person can gain access to the contents of the package. Typically, means for preferential tearing are provided for easy removal of the header. The tack seal contributes to the maintenance of the cleanliness and aesthetics of the package, while still allowing easy removal of the header. The tack is light (i.e., low bond strength or pull-off force) in order to not make it significantly more difficult to open the package.

  • Publication number: 20050268783
    Abstract: A composition of and a method of making high performance hollow fiber membranes is described. The membranes have a high resistance to plasticization by use of a predetermined amount of crosslinking. The preferred polymer material for the membrane is a polyimide polymer comprising covalently bonded ester crosslinks. The resultant hollow fiber membrane exhibits a high permeability of CO2 in combination with a high CO2/CH4 selectivity. Another embodiment provides a method of making the hollow fiber membrane from a monesterified polymer followed by final crosslinking after hollow fiber formation.

  • Patent number: 6963826
    Abstract: Information is received from a plurality of CRM/SFA sources within an operating environment and is mapped to specific business processes. Transactional data, learning systems information, technical support information and usage data is aggregated and used to provide a dimensional model of the data. The present invention provides a mapping view of technology usage to one or more business practices and reflects, among other things, the extent to which customer relationship management technology is impacting sales representative performance.

  • Publication number: 20050235602
    Abstract: Methods and apparatus for controlling the registration of one elongated continuous structure (e.g., plastic zipper) with attachments or formed features (e.g., sliders or pre-seals) as it is fed to a sealing station, where it is joined to another elongated continuous structure (e.g., packaging film) with formed features (e.g., thermoformed pockets). The latter elongated continuous structure will be intermittently advanced through the machine, pulling the former elongated continuous structure joined thereto forward. Registration is accomplished by tacking the respective elongated continuous structures together while the respective features on the elongated continuous structures are in proper registration. After tacking, the respective portions of the elongated continuous structures immediately downstream of the tack zone are advanced to the sealing station in proper registration.

  • Publication number: 20050224688
    Abstract: A plinth is disclosed for the support of an attached object. The plinth has a fixing portion for embedding into a secure foundation. The plinth also has a base plate for support of the object, through support means, which are arranged to crumple under an impact, without the object becoming detached from the plinth.

  • Patent number: 6945738
    Abstract: Embodiments of the present invention are directed to a method and apparatus for safety protection control of temporary roof support. In one embodiment, a temporary roof support has a load sensing member. In another embodiment, a beam structure of temporary roof support is supported by a load sensing pin. Strain gages are installed within the pin to measure the load placed upon the pin. An unusually high load being sensed by the pin indicates that the roof has fractured and the temporary roof support is supporting loose rock. In one embodiment, when an unusually high load is measured at the pin, the temporary roof support controls at the front of the machine are disabled. A second set of remotely located temporary roof support controls remain operative. In one embodiment, the second set of controls is located at the rear of the machine.

  • Publication number: 20050166002
    Abstract: An electronic signal processing apparatus contains a security key memory. Unless the security key memory contains a prescribed security key, a user is unable to operate the electronic signal processing apparatus. An intrusion detection and protection mechanism prevents access to the security key in the event of a compromise in the integrity of a housing for the security key memory. For this purpose, an intrusion detection circuit is adapted to monitor the integrity of the housing. A memory contents modification circuit is operative, in response to the intrusion detection circuit detecting a compromise in the integrity of the housing (opening of the housing), to modify (e.g., scramble) the contents of the security key memory and thereby effectively remove the security key from the security key memory.

  • Publication number: 20050102046
    Abstract: A system and method for remote monitoring of material storage levels for dry bulk goods, wherein an independent entity, such as a transportation carrier, can continuously monitor raw material supply levels at a remote manufacturing plant, and, based on projected usage rates, place timely orders on behalf of the plant, with preselected vendors, to replenish depleted raw materials. The transportation carrier can then coordinate material shipments from the vendor to the manufacturing site using its own trucks. In this manner, the task of maintaining sufficient on site raw material storage levels is completely removed form the manufacturing plant.
