  • Patent number: 10073115
    Abstract: A self-diagnostic accelerometer (SDA) field programmable gate array (FPGA) may be capable of real time or near-real time diagnostic processing to determine potential accelerometer issues during flight or other mission critical operational situations. The SDA FPGA may determine accelerometer structural health and an attachment condition using an electronics system that is smaller, more energy efficient, and more cost effective than previous diagnostic tools. Advantages of the system may include diagnosing sensors automatically, immediately, actively (i.e., confirming the fault), and consistently, without the influence of a human operator. Customizable SDA algorithms may be adjusted to the specific needs of the sensor/environment.

  • Patent number: 10074764
    Abstract: A method of forming low-energy x-ray absorbers. Sensors may be formed on a semiconductor, e.g., silicon, wafer. A seed metal layer, e.g., gold, is deposited on the wafer and patterned into stem pads for electroplating. Stems, e.g., gold, are electroplated from the stem seed pads through a stem mask. An absorber layer, e.g., gold, is deposited on the wafer, preferably e-beam evaporated. After patterning the absorbers, absorber and stem mask material is removed, e.g., in a solvent bath and critical point drying.

  • Patent number: 10059682
    Abstract: A method for preparing asymmetric 3,4?-(hexafluroisopropylidene) dipthalic anhydride (a-6FDA) and asymmetric 3,4?-(methylene)diphthalic anhydride (a-MDPA) from asymmetric 2,3,3?,4?-benzophenone dianhydride (a-BTDA). First, a-BTDA is converted to its corresponding N-alkyl or N-phenyl bisimides by reacting with either methylamine or aniline. The sequential addition of two trifluoromethyl (CF3) groups to the carbonyl unit of a-BTDA produce the corresponding bisimides of asymmetric 6FDA, which is hydrolyzed to the asymmetric 6F-tetracarboxylic acid followed by cyclodehydration to obtain asymmetric 6F-dianhydride (a-6FDA). Separately, the carbonyl unit of bisimides of a-BTDA is reduced to a methylene unit to afford the corresponding bisimides of asymmetric 3,4?-(methylene)diphthalic anhydride, which is hydrolyzed to the asymmetric methylene tetracarboxylic acid followed by cyclodehydration to obtain 3,4?-(methylene)diphthalic anhydride (a-MDPA).

  • Patent number: 10044320
    Abstract: Aspects of the present disclosure involve a system and method for generating noise waves at millimeter wave frequencies. A noise source generator is designed to be connected to a crystalline structure for efficient heat transfer and compatibility with millimeter wave receivers. The use of crystalline structure coupled to the noise source generator allows heat from a biasing device, such as a diode, to be carried away such that the diode is able to generate noise waves while being reversed biased without compromising the device. In another embodiment, the noise source generator includes the use of a backshort transmission line with vias that is connected to the biasing device for heat transfer from the biasing device to the backshort.

  • Patent number: 10036632
    Abstract: Aspects of the present disclosure involve a system and method for performing radio frequency interferometry using optical fiber sensing. Optical fiber sensing is performed as a reference signal is defined and compared, in the optical domain, to incoming signals to obtain interference fringe patterns that can be used to decode phase shift offsets with respect to the designated reference signal. The phase shift offsets can be determined by first optically modulating the reference and incoming signals using a laser source as the carrier. In the optical domain, the reference and incoming signals are combined using an optical coupler and then converted back to the electrical domain for processing.

  • Patent number: 10019835
    Abstract: The invention is a system and method of compressing terrain data to be used to render a three-dimensional map representation of the terrain data. In general, the invention operates by first selecting the boundaries of the terrain data and to be compressed and dividing the terrain data into regular geometric areas. Next, a type of free-edged, planar geometric surface is defined which is used to approximate the terrain data for each regular geometric area. The approximations are checked to determine if they fall within user selected tolerances. If the approximation for a specific regular geometric area is within the user specified tolerances, the data is saved for that specific regular geometric area. If the approximation for a specific regular geometric area falls outside the user specified tolerances, the regular geometric area is divided and a free-edged, planar geometric surface approximation is made for each of the divided areas.
