Abstract: A thermoelectric generator and methods of fabricating a thermoelectric generator are disclosed. An exemplary thermoelectric generator includes an upper electrode, a lower electrode, and a thermocouple disposed between the upper electrode and the lower electrode. The upper electrode, the lower electrode, and the thermocouple are configured to effect heat flux laterally through the thermocouple.

Abstract: A mesh sensor system for measuring the performance of directed energy weapons at a target has been developed. The mesh sensor system measures the laser irradiance and the thermal response on the target. The system includes a plurality of sensors arranged on the target surface and a plurality connecting lines that connect with the sensors to provide power and retrieve data from the sensors.

Abstract: A system for group facial recognition includes a target extractor for extracting target images from a scene image; a target image classifier for comparing a target image to a database of known identities and allocating classification scores for identities; a relationship database providing relationship scores between known identities; and means for applying the relationship scores to the classification scores to improve classification of a target image. Two or more target images are extracted from a scene image and it is determined that a first target image is one of a first set of identities, each with a classification score, and that a second target image is one of a second set of identities, each with a classification score. A relationship score is determined for each of the first set of identities giving the relationship to one or more of the second set of identities. The relationship score is applied to the classification score for the first target image.

Abstract: A method for creating hierarchical classifiers of software components in a learning system, each software component comprising an identifier and a rule for processing an input message, the method comprising the steps of: receiving an input message by a first software component; parsing the input message to identify an input value; seeking a second software component having an identifier matching the identified input value; in the event that the seeking step fails to locate a match, creating a second software component and assigning an identifier to the created second software component, the identifier matching the identified input value.

Abstract: System, method and program product for detecting malicious software within or attacking a computer system. In response to a system call, a hook routine is executed at a location of the system call to (a) determine a data flow or process requested by the call, (b) determine another data flow or process for data related to that of the call, (c) automatically generate a consolidated information flow diagram showing the data flow or process of the call and the other data flow or process. After steps (a-c), a routine is called to perform the data flow or process requested by the call. A user monitors the information flow diagram and compares the data flow or process of steps (a) and (b) with a data flow or process expected by said user. If there are differences, the user may investigate the matter or shut down the computer to prevent damage.

Abstract: A spacecraft thruster and propulsion method comprising a laser directed at an ablation target, wherein when the laser is operating, material ablates from the ablation target, thereby generating a thrust vector on the spacecraft.
