Abstract: A dual field-of-view optical imaging system is provided for obtaining two images of a scene, each image having a different field of view. The dual field-of-view optical imaging system includes a frontal dual focus lens, the dual focus lens having a central zone of focal length f1 producing a wide field-of-view image at a first focal plane and a peripheral zone of focal length f2 greater than f1 producing a narrow field-of-view image at a second focal plane; and a detector for detecting and acquiring the wide field-of-view image and the narrow field-of-view image, the detector being movable along an optical path for selective positioning at the first focal plane or the second focal plane.

Abstract: An orthogonal linear frequency modulation (OLFM) communications system where orthogonal sub-sweeps experience the same channel condition and subsequent SNR allowing for uniform power allocation and data modulation per sub-sweep and an efficient exchange of modulation parameters for more optimized communications.

Abstract: A wireless communication system includes a plurality of headsets, each embodying a wireless transceiver, and wherein communication can be established between the headsets via the wireless transceivers over a network in which the headsets act as nodes.

Abstract: A flight control computer for controlling an actuator responsive to a flight control command is described. The system includes a first, second, and third pair of processors. Three different processor types make up the three pairs of processors and the pairs of processors differ between all processor pairs. A method aspect of providing a robust flight control computer controlling actuator responsive to a flight control command includes arranging interconnected pairs of processors using different processor types such that the pairs of processors differ between all processor pairs. An identical flight control command is received at each processor pair. A processor pair is declared to be in failure and processing is transferred to another processor pair if the compared output of each processor pair after receiving the identical flight control command differs between the processors in the pair.

Abstract: A driver vision enhancing system having a variable field of regard and a method of controlling the field of regard of a driver vision enhancing system. The system includes a housing, a movable sensor assembly located within the housing, a radiation detector connected to one end of the sensor assembly, and an actuator connected to the housing and able to contact the sensor assembly to move the sensor assembly in the housing and thereby move the radiation detector. The method includes moving a radiation detector as part of a driver vision enhancing system in a vertical direction within an image plane of the driver vision enhancing system.
