    Abstract: A system and method for increasing the fiber coupling efficiency of diode lasers is disclosed. The diode laser has a diode pump source for generating a force to pump a laser and a double clad fiber directly coupled to the diode pump source instead of coupling to the multimode fiber. The pumped laser is transmitted directly through the double clad fiber thereby increasing the coupling efficiency of the diode pump source. At least one connector is utilized for connecting the double clad fiber and the diode pump source. The connector has at least one adhesive placed in contact with an acrylate coating and not in contact with a glass cladding of the double clad fiber to avoid cladding stripper and fiber splice thereby increasing the fiber coupling efficiency.

    Abstract: An athermal locking mechanism apparatus for large optic mounts is disclosed. The apparatus comprises at least one locking nut, at least one flexurized spring collet attached to a rigid base structure, a pivot shaft engaged with an optical yolk on a rotational axis of symmetry and a plurality of threads that joins the locking nuts with the flexurized spring collet The threads provide an increased level of a radial clamping force onto the pivot shaft, The interference generated between the locking nut and the spring collet causes all flexures to squeeze down onto the shaft, applying a purely symmetric radial force during the locking process. This eliminates any induced rotational torque and prevents the optical element from moving during the locking process after being properly aligned.

    Abstract: An imaging sensor using a novel bit line processing circuit, that circuit, and the method of processing the pixel outputs from an image sensor using that processing circuit are disclosed. The image sensor includes an array of pixel sensors, a signal digitizing circuit, and a digitizing controller. Each pixel sensor generates a voltage signal that is a function of a charge on the photodetector in that pixel sensor, and couples that voltage signal to a bit line in response to a first signal. The signal digitizing circuit is connected to the bit line, the digitizing circuit converting the voltage signal to a plurality of output digital values, the output digital values having selectable levels of digitization noise. The digitizing controller generates the level of noise based on the voltage signal. The signal digitizing circuit includes a variable gain amplifier and an ADC having a fixed number of bits.

    Abstract: A computerized method for a distributed assured network system includes a plurality distributed monitoring nodes for sequential feeding the content of respective information sources to a detection agent. The detection agent uses an SPRT-based distributed sequential misbehavior detection scheme to process each MN observation with the probability of a false alarm PFA and probability of a miss detection PMD until a reliable decision can be made that either there is no malicious or faulty behavior detected, or that malicious or faulty behavior is detected. A cognitive reputation agent is provided within a DBG framework processes the output or detection metric from the detection agent relative to past behavior of the information sources to provide a reputation metric to a trust indication that provides an output representing the trustworthiness of information sources.

    Abstract: A Multi-Cycle Digital High Power Microwave (MCD-HPM) source includes a microwave transmission line (MTL) to which a plurality electrically charged thin film transmission lines (TFTL's) are connected by switches. The switches are activated in sequence to generate a square wave at a microwave output frequency. The activation signal is controlled by a free space time delay, which can vary the timing and/or routing of the activation signal by modifying at least one free space element, thereby adjusting the switch activation timing and varying the output frequency. In embodiments, the switches are photo-conducting switches, the activation signal is a laser beam, and the switch timing is varied by reorienting and/or repositioning mirrors and/or other elements in the free space time delay. The elements can be manually adjusted, or mounted on motorized stages and automatically controlled. Optical amplifiers can be included to compensate for losses in the time delay elements.
