Patent number: 9036250Abstract: Techniques and structure are disclosed for implementing a spatial walk-off compensation mechanism having an integral tilt function. In some embodiments, the mechanism may comprise a tilt-ball mount having an integrated walk-off compensation medium. In some embodiments, the mechanism may be configured to receive an output beam from a non-linear converter (e.g., optical parametric oscillator or OPO) implementing a non-linear medium comprising a bi-refringent material (e.g., zinc germanium phosphide, or ZnGeP2; cadmium silicon phosphide, or CdSiP2). In some embodiments, the walk-off compensation medium may comprise the same material and/or have the same cut as the non-linear medium.

Patent number: 9025230Abstract: An optical LOS toggle uses two refractive optical elements located in the afocal space of an optical sensor. Optical surfaces of the two elements are shaped appropriately to work in combination with lateral displacements of the two elements such that the LOS angle is shifted. For a prescribed, discrete LOS shift, the optical image quality of the toggle module is corrected by a combination of aspheric shapes and diffractive surfaces on the optical surfaces of the two elements. To maintain performance along any radial direction and simplify fabrication, these aspheric or spheric shapes and diffractive surfaces should be rotationally symmetrical. Image quality is further improved through proper selection of the optical materials used to construct the optical elements.Type: GrantFiled: September 7, 2012Date of Patent: May 5, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Stephen F.

Patent number: 8994434Abstract: A method for dealing with high inrush current when voltage is applied to mixed voltage logic integrated circuits is disclosed. A depletion N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) or junction Field Effect Transistor (JFET) is added to a linear voltage regulator in mixed voltage logic integrated circuits. The Field Effect Transistor (FET) is utilized to allow the core voltage to come up with Input/Output voltage prior to turn-on of linear voltage regulator. Turn-on state of FET allows the core voltage to rise with Input/Output voltage until the FET threshold is reached across the gate. When threshold is reached, the FET turns off to allow linear voltage regulator turn on and take over supply power.Type: GrantFiled: February 12, 2013Date of Patent: March 31, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Scott C.

Patent number: 8996869Abstract: A system and method for converting a device between an authorized device and an unauthorized device may include a crypto ignition key (CIK) and a mission module. The CIK may store an original device number corresponding to a device. The mission module typically loads a local mission and a key, decrypts the local mission with the key to produce a decrypted local mission, and generates an internal file encryption key (IFEK) and an internal split. The mission module may then encrypt the decrypted local mission to produce an encrypted local mission and then erase the IFEK. The mission module, when attached to the device, may read an additional device number from the device and recreate the IFEK based on the additional device number and the internal split. The mission module may decrypt the encrypted local mission and install the results in the device to convert the device into an authorized device.Type: GrantFiled: July 1, 2013Date of Patent: March 31, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Jeffrey B.

Patent number: 8995494Abstract: Techniques and architecture are disclosed for providing a laser system. In one specific example embodiment, the system includes a thulium-doped fiber laser coupled by silica glass fiber to a remote optical converter (ROC) including a Ho:YAG laser and, optionally, an optical parametric oscillator (OPO) utilizing zinc germanium phosphide (ZnGeP2; ZGP) or orientation-patterned gallium arsenide (OPGaAs). The fiber laser may emit a low-peak-power, continuous wave pump signal that pumps the Ho:YAG laser, which in turn emits a higher-peak-power, pulsed signal. When included, the OPO can be used to convert the resultant, pulsed signal to a longer wavelength (e.g., about 2-5 ?m, or greater). In some cases, distributed architecture and reduced weight/bulk may be realized while eliminating the need to actively cool the ROC for operation, for example, over a broad temperature range (e.g., ?55-125° C.). Also, methods of preparing high-peak-power, pulsed signals using such systems are disclosed.Type: GrantFiled: April 6, 2012Date of Patent: March 31, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Leonard A Pomeranz, Joseph M Owen, Michael J.
