Abstract: A system and method for distinguishing a first light source from other light sources utilizes an image receiver that can selectively engage and disengage a filter. The filter can be configured to block bands of light corresponding to the light being emitted by either the first source or the other sources. By alternately engaging and disengaging the filter from the image receiver, the first light source may be distinguished from other light sources.

Abstract: A system (126-129) detects transmission of potentially malicious packets. The system (126-129) receives packets and generates hash values corresponding to each of the packets. The system (126-129) may then compare the generated hash values to hash values corresponding to prior packets. The system (126-129) determines that one of the packets is a potentially malicious packet when the generated hash value corresponding to the one packet matches one of the hash values corresponding to one of the prior packets and the one prior packet was received within a predetermined amount of time of the one packet. The system (126-129) may also facilitate the tracing of the path taken by a potentially malicious packet. In this case, the system (126-129) may receive a message that identifies a potentially malicious packet, generate hash values from the potentially malicious packet, and determine whether one or more of the generated hash values match hash values corresponding to previously-received packets.

Abstract: A system and method for performing source path isolation in a network. The system comprises an intrusion detection system (IDS), a source path isolation server (SS1) and at least one router configured to operate as a source path isolation router (SR1) operating within an autonomous system. When IDS detects a malicious packet, a message is sent to SS1. SS1 in turn generates a query message (QM) containing at least a portion of the malicious packet. Then, QM is sent to participating routers located one hop away. SR1 uses the query message to determine if it has observed the malicious packet by comparing it with locally stored information about packets having passed through SR1. SR1 sends a reply to SS1, and SS1 uses the reply to identify the ingress point into the network of the malicious packet.

Abstract: A system (200) detects transmission of potentially malicious packets. The system (200) receives, or otherwise observes, packets and generates hash values based on variable-sized blocks of the packets. The system (200) then compares the generated hash values to hash values associated with prior packets. The system (200) determines that one of the received packets is a potentially malicious packet when one or more of the generated hash values associated with the received packet match one or more of the hash values associated with the prior packets.

Abstract: Systems and methods for optimizing the process of segregating undesired mail using an incoming mail sorter are described and in certain examples, systems including those for using information feed-forward and/or feedback systems for making selective physical delivery decisions in the process of sorting and delivering incoming physical mail are described.

Abstract: An EL device is presented which consists of a simple three active layer construction. A layer of a dielectric material, a traditional EL phosphor layer, and a quantum dot layer are present between an electrode and a transparent electrode. The EL device is operated efficiently by an AC source. Quantum dots which emit in the visible spectrum are used. The EL device is fully color tunable by altering the composition and thickness of the layers.

Abstract: A system and method for identifying target packets in a network. The invention identifies packets by computing a hash value over at least a portion of a packet passing through a network device such as a router. The hash value is used as an address, or index, into a memory. The hash value identifies a unique memory address and a flag is set at the respective memory location. When a target packet is detected elsewhere in a network, the network device receives a query message containing a hash value of the target packet. The network device compares the target packet to the hash values in memory. A match between the hash value in memory and the hash value in the query message indicates the target packet was observed by the network device. After a match is detected, the network device makes a reply available to the network.

Abstract: In accordance with an embodiment of the invention, a method for creating a self-authenticating document is disclosed. The method comprises: providing a base substrate forming the document; printing an authentication seal on the document, the authentication seal comprising a printed portion comprising an ink creating a bleed area on the document where the ink and the substrate interact; and obtaining unique bleed properties of the bleed area. The bleed properties are obtained by scanning the bleed area upon termination of bleeding or drying to provide a description of the ink and substrate interaction to generate an identifier code representing the unique bleed properties. The method further comprises generating a signature of the identifier code, encoding the identifier code in an information carrier, and associating the information carrier with the document or storing the signed identifier code in a remote verification seal code that is not printed on the document.

Abstract: A non-powered roller conveyor for conveying parts along a conveyor path includes a downwardly sloped conveyor support frame with a plurality of rollers rotatably mounted along the frame. The rollers comprise a length of prefabricated roller top conveyor chain mounted along a top surface of the conveyor frame. The conveyor chain includes a plurality of links connected together by pivotal connectors that permit sideways articulation of the links with respect to each other. Transverse rows of rollers are rotatably mounted on the links to permit products to roll along the conveyor. The rollers are easily replaceable when necessary. The conveyor follows a downwardly extending spiral path comprising a series of inclined straight sections interconnected by inclined bend sections. Both the straight and bend sections are inclined so that parts roll along the conveyor path under the influence of gravity.
