  • Publication number: 20240141715
    Abstract: A fenestration assembly includes a plurality of lineal segments joined at corners. Each of the lineal segments extend between first and second ends. One or more of the lineal segments of the plurality of lineal segments is a composite lineal segment and includes a first component lineal segment and a second component lineal segment. The first and second component lineal segments are coupled at an assembly joint in an assembled configuration.

  • Publication number: 20240118204
    Abstract: A semiconducting nanocrystal (quantum dot or QD) and ferric dithiocarbamate complex (QD-Fe(DTC)3) operate as a sensing system to detect nitric oxide (NO) in ambient conditions using fluorescence resonance energy transfer (FRET). The sensing system comprises two components: (1) an energy donor in the form of a dihydrolipoic acid (DHLA)-coated QD with strong fluorescence emission, and (2) an energy acceptor in the form of a ferric ion-dithiocarbamate complex (Fe(DTC)3) that binds onto the QD surface via carboxylate coordination. The ferric ion in the QD-Fe(DTC)3 complex acts a strong energy acceptor, resulting in weak fluorescence (FL) emission (“turn-off”) of the QD when excited using 405 nm light. In the presence of NO, ferric ion (3+) reduces to ferrous (2+), with decreased ability to accept energy from the QD, in turn appearing as increased FL emission from the QD (“turn-on”) as a sensing signal.

  • Patent number: 9541540
    Abstract: A non-destructive method for determining an amount of temperature exposure to a Bismaleimide Resin (BMI) matrix substrate, the method includes determining component data of a Bismaleimide Resin (BMI) matrix component via fourier transform infrared (FTIR) spectroscopy; correlating the component data to model data to determine a structural debit from temperature exposure; and bounding a structurally damaged area in response to the correlating.

  • Publication number: 20130288210
    Abstract: A semi-automated maintenance management system instructs a technician to disassemble a component into parts, compare each part to a reference entry and identify any discrepancies between the part and the reference entry, repair or replace the component according to instructions automatically provided for the discrepancy when a known discrepancy is found, create a disposition when an unknown discrepancy is found, and reassemble the component.

  • Publication number: 20120272637
    Abstract: An example method of replacing an aperture in a component includes placing layers of a filler material into a first aperture. The layers of the filler material arranged in a stacked relationship relative to each other within the first aperture. The method cures the filler material and establishes a second aperture that is at least partially defined by the filler material.

  • Patent number: 7502673
    Abstract: A method for remote vehicle communication is provided. The method monitors, stores and/or transmits data representative of the operation of a component or system, whereby the transmitted data may be analyzed and vehicle performance improved through the analysis thereof. Additionally, the vehicle systems are remotely accessible such that a technician can remotely analyze the vehicle without taking control of the vehicle away from the consumer.

  • Patent number: 7406624
    Abstract: A method is provided for saving system information immediately following a hardware or software failure that causes a processor to reset. After failure is imminent and before the processor allows the reset to occur, the processor is instructed to copy a fixed amount of the system stack SRAM, in addition to any processor registers that can be used to determine the reset cause, into a preserved area of SRAM. During the initialization sequence, the preserved area of SRAM is tested, but not overwritten. This allows all of the preserved SRAM data including previous stack contents and register settings at the time of the failure to be available for analysis.

  • Patent number: 7350097
    Abstract: A method for recovering control of a continually resetting control module is provided. The method recovers control by monitoring a vehicle's communication links for a very short period each time the boot program starts and before control is passed to the application program. Alternatively, control may also be recovered using a running reset counter (RSC) that increments every time the boot program is entered via an abnormal condition. After recovering control, the control module can communicate with an external tool to diagnose and/or reprogram the control module and thereby prevent continual reset.
