Abstract: A system and method for reducing laser communication terminal pointing uncertainty. The method trains an artificial neural network (ANN) with input data characterizing terminal pointing error and dependent parameters. The method inputs the trained ANN a set of data of these dependent parameters with unknown pointing error. The method uses the ANN output to apply corrections to the terminal pointing solution to reduce pointing uncertainty. The method can condition the ANN generated corrections to avoid cases where application of the ANN correction could exceed the original pointing uncertainty. This conditioning includes computing the Euclidean distance between current ANN input parameter values and values in the ANN training dataset, and bounding the allowed magnitude of the ANN pointing correction. The method can train the ANN incrementally during terminal operation for real-time updates or train the ANN offline with gathered data and implement the trained ANN on the terminal for subsequent links.

Abstract: A counter measure system is provided having a unitary infrared transparent dome including a look angle greater than 180. The dome has two hemispherical regions, with a second region having a truncated bottom end defining an opening to a central cavity inside which electro-optical elements are disposed. The electro-optical elements can view outward through the dome at the look angle. The second region on the dome has a complementary curvature as the first region by continuing a similar radius beyond a transverse horizontal axis or equator. The dome is mounted to a base, which also may be referred to as a bezel. The base defines a rabbet extending circumferentially about the base imaginary center defining an aperture. The base and the dome are formed from different materials but have equivalent coefficients of thermal expansion. In one embodiment the dome if formed from sapphire and the base is titanium.

Abstract: An infrared countermeasure system comprises a transparent infrared camera dome with an anti-icing surface coating.

Abstract: Systems and methods for assessing transaction risk. A consumer tenders a transaction card to a merchant to purchase a good or service. A payment device of the merchant, such as a merchant's payment terminal or mobile communication device, is used to process the payment utilizing a risk assessment system. Card data received by the payment device is sent to the risk assessment system, which processes card data and generates an indicator representing the risk associated with accepting payment using the card. The indicator is sent to the payment device to provide the merchant input regarding risk associated with using the card (e.g., likelihood of fraud or chargeback) in a seamless manner. If the risk level is too high, the merchant may reject the card. The risk indicator may be based on different types of data from different sources, e.g., data from a first source related to the credit history of the consumer and data from a second source related to the identity of the consumer.

Abstract: Apparatus, methods, and computer program products are disclosed that teach methods for establishing context of a subsequent electronic real-time communication. One method detects a connection attempt that is initiated by an instigator-identifiable for a subsequent electronic real-time communication that is directed to a target-identifiable. The instigator-identifiable is associated with a first identification characteristic and the target-identifiable is associated with a second identification characteristic. This method subsequently retrieves a reminder reference that is responsive to the first identification characteristic and the second identification characteristic and presents the reminder reference to the target-identifiable. The method also establishes the subsequent electronic real-time communication between the instigator-identifiable and the target-identifiable.
