  • Patent number: 8442184
    Abstract: An imaging system includes a radiation source (106, T1, T2, T3) that rotates about an examination region and emits radiation that traverses the examination region. The radiation source (106, T1, T2, T3) emits radiation having an energy spectrum that is selectively alternately switched between at least two different energy spectra during an imaging procedure. The system further includes an energy-resolving detector array (116, D1, D2, D3) that detects radiation traversing the examination region. The energy-resolving detector array (116, D1, D2, D3) resolves the detected radiation over at least two different energy ranges and produces energy-resolved output signals as a function of both emission energy spectrum and energy range. The system further includes a reconstructor (126) that performs a spectral reconstruction of the energy-resolved output signals. In another embodiment, the detector array (116) includes a photon-counting detector array (116).

  • Patent number: 8442186
    Abstract: A system and methods for characterizing regions within, or on, an inspected object, wherein a lower-Z scattering material and a higher-Z material may both lie along a common line of sight. The inspected object is scanned with penetrating radiation characterized by an energy distribution, and penetrating radiation scattered by the inspected object is detected in a manner that generates two detector signals that distinguish between materials of higher and lower effective atomic number under distinct sets of conditions with respect to the energy distribution of the penetrating radiation. An image is generated, based on a function of the two detector signals, as is a differential image, so as to allow distinction of higher-Z and lower-Z materials.

  • Patent number: 8442193
    Abstract: A method and device for preventing fraud in collect calls from a domestic origin point to an international terminating point through a long-distance telecommunications system is described. In the system and method, a Screening for International Calls database is added to the call processing platform. This Screening of International Calls database contains records keyed by country codes, and each record has a blocked collect call field listing destination numbers that are blocked from receiving collect calls. When a domestic-to-international collect call is made, the record corresponding to the country code of the international terminating point of the collect call is retrieved from the Screening for International Calls database. This record is checked to determine if the destination number of the collect call matches any destination numbers listed in the blocked collect call field of the country code database record. If there is a match, the call is blocked.

  • Patent number: 8442202
    Abstract: A telecommunications system is disclosed that enables a user to pair a desk set that is an extension of a private-branch exchange with a cell phone that is accessible via the Public Switched Telephone Network. One feature of the telecommunications system enables a call that is directed to the user's desk set to be automatically forwarded to the user's cell phone. This is advantageous to the user because it provides the illusion to the caller that the user is physically in her office when she is not necessarily there. A similar feature also provides the illusion when a third party initiates a call that connects the user's cell phone to a called party. Such a third party includes a computer-telephony integration (CTI) application in a telephone telemarketing center, which automatically places many outgoing telephone calls.

  • Patent number: 8442203
    Abstract: An active call between two parties can be marked as a non-preemptable call if one of the two parties is an authorized agency that desires to prevent premature termination of the call by a third party. The authorized agency sends a signal to a main switch to indicate that non-preemptable call status is desired. The newly established call status is then propagated to other nodes in the system to prevent premature call termination. Non-preemptable status can also be granted to some calls based on the destination of the called number, such as in 911 calls.

  • Patent number: 8442209
    Abstract: A system and method for processing out-of-order caller responses during automated call processing is provided. A call session of a caller into a call center is monitored. The call session includes a non-sequential dialogue between the caller and the call center. An interaction with the caller is based on a script. Ordered information-gathering queries, including automated voice prompts are sent to the caller by executing the script. Responses from the caller are evaluated against a topic of conversation addressed in the script through call disposition criteria. A determination is made as to whether an affect on the ordering by the call disposition criteria is met through the responses. The ordering of the information-gathering queries is dynamically modified prior to selecting a next of the information-gathering queries to send.

  • Patent number: 8442218
    Abstract: A method and apparatus for a system and process for generating a hashing value using any number of cryptographic hashing functions. The hashing process receives an input value to be hashed. The input value is cyptographically hashed and augmented. The augmented value is then cryptographically hashed. The process then iteratively applies a set of non-linear functions to these values. Each iteration maintaining a ‘left half’ and ‘right half.’ After the last iteration, the left and right portions are concatenated to form a hash value that is output.

  • Patent number: 8442221
    Abstract: An image encryption method is described for encrypting an images using an encryption key. The encryption method includes dividing the image into pixel groups and shifting the location of the pixel groups according to an encryption key, and reordering the bits of the pixel values of the image according to an encryption key. Each shifting and reordering is done according to a shifting patterns that is defined by a shifting rule and the bit values of a bit sequence generated from the encryption key. The encrypted image is embedded in a cover image using less significant bits of the cover image for transmission or storage. Corresponding decryption method is also provided. Also described are various applications of image encryption methods in secure handling of digital images, including secure scanning, secure printing, secure ID scanning, secure check reading, remote picture ID verification, and remote document submitting and receiving systems.

  • Patent number: 8442230
    Abstract: A light-weight resilient mechanism is used to synchronize server secure keying data with member devices in a highly-scalable distributed group virtual private network (VPN). A server device generates an initial secure keying data set, for the VPN, that includes a first version identifier, and sends, to member devices and via point-to-point messages, the secure keying data set. The server device sends, to the member devices, heartbeat push messages including the first version identifier. The server device generates an updated secure keying data set with a second version identifier and sends, to the member devices, a key push message that includes the updated data set. The server device sends, to the member devices, heartbeat push messages including the second version identifier. Member devices may use the first and second version identifiers to confirm that secure keying data sets are current and quickly identify if updates are missed.

  • Patent number: 8442231
    Abstract: A mobile communications network has mobile communications capabilities and supports a secure messaging service, such as an SMS messaging service, that allows a message sender and at least one message receiver (at least one among the message sender and the message receiver being a user of the mobile communications network) to exchange messages encrypted by means of a cryptographic process performed by the message sender, so as to obtain an encrypted message that can be decrypted by a corresponding cryptographic process performed by the intended message receiver. End-to-end security of the exchanged message is thus achieved. A cryptographic algorithm, exploited by the user of the mobile communications network for performing the cryptographic process, is modified by exploiting the mobile communications capabilities of the mobile communications network. Robustness and reliability over time of the end-to-end security messaging is improved.
