Abstract: A device for managing secure communications by examining message packets to detect and control the use of encryption keys noninvasively examines an incoming message packet according to typical cryptographic protocols and sequences. If an incoming packet exhibits the use of an encryption key, such as via IKEP, IPsec, or PPTP, the device processes the packet to attempt to find the corresponding encryption key. The device compares the key to a list of known suspect keys to determine a blocked status. If the key is not on the list, a sequence of authorization rules concerning prohibited key usage attempts to determine a result. The authorization rules examine available keying attributes from the message packet, possibly via a remote server, and compute an indication concerning key usage. If the authorization rules are still undeterministic of usage of the key, the device uses a default action.

Abstract: An optical device for a wavelength division multiplexing system has a telecentric lens system and a signal-processing optical element, where the signal-processing optical element performs switching, attenuation, or other optical signal processing for the optical device.

Abstract: A method for filling closed regions in a drawing using a region filling tool. Rather than selecting individual regions to fill, or filling based on style-by-layer techniques, the user creates a path or an area boundary to identify the regions to be filled. A graphics application may then fill each region that intersects the path or area boundary with a selected color or graphical style. In this manner, multiple regions in the drawing may be identified using one interaction with the region filling tool, allowing the user to more efficiently and intuitively fill regions in the drawing with the selected color or graphical style.

Abstract: One embodiment of the present invention sets forth a technique for representing and managing a multi-architecture co-processor application program. Source code for co-processor functions is compiled in two stages. The first stage incorporates a majority of the computationally intensive processing steps associated with co-processor code compilation. The first stage generates virtual assembly code from the source code. The second stage generates co-processor machine code from the virtual assembly. Both the virtual assembly and co-processor machine code may be included within the co-processor enabled application program. A co-processor driver uses a description of the currently available co-processor to select between virtual assembly and co-processor machine code. If the virtual assembly code is selected, then the co-processor driver compiles the virtual assembly into machine code for the current co-processor.
