  • Patent number: 11605370
    Abstract: Disclosed are methods and systems for providing audible flight information to an operator of an aircraft. A method, for example, may include receiving flight information detected by one or more sensors positioned on the aircraft, causing an image to be displayed on a display device, the image including a plurality of text items corresponding to the flight information, receiving a first operator selection indicative of one or more of the text items, parsing the one or more text items to generate a set of intermediate data, synthesizing audio data based on the intermediate data, and causing audible content corresponding to the audio data to be emitted by one or more audio emitting devices, wherein the audible content includes speech corresponding to the flight information.

  • Patent number: 9012844
    Abstract: A single-shot pulse contrast measuring device based on non-harmonic long-wavelength sampling pulse includes a long-wavelength sampling light generation unit, a large-angle non-collinear sum-frequency cross-correlation unit and a high sensitivity signal receiving unit. The long-wavelength sampling light sum-frequency cross-correlator can allow that the beams are interacted with each other at the large non-collinear angle in the quasi-phase matching crystal, match the measuring window of the high sensitivity signal receiving system, and is in favor of eliminating the scattered light noise, thereby achieving the single measurement of the pulse contrast with large temporal window and high dynamic range. The single-shot pulse contrast measuring device of the present invention has good extensibility at the temporal window and dynamic range, and is adapted for measuring the contrast of the high-power laser with various wavelengths.

  • Patent number: 8071934
    Abstract: A system for detecting single-shot pulse contrast includes a correlator generating a correlation signal, a spectral filter filtering light signals having wavelengths different from the correlation signal, a fiber array comprising a plurality of fibers with different lengths for transmitting the correlation signal in parallel forming parallel correlation signals, and a fiber bundle bounding the fibers at the end thereof for converging the parallel correlation signals, wherein due to different lengths of the fibers, the parallel correlation signals are converted into serial correlation signals at end of the fibers, a plurality of fiber attenuators spliced into at least one of the fibers respectively for attenuating the parallel correlation signals, a detector for detecting the serial correlation signals to produce analog signals, an A/D convertor converting the analog signals to digital signals, and a computer for processing the digital signals for retrieving the single-shot pulse contrast.

  • Publication number: 20050038450
    Abstract: A curved suture applicator is provided for facilitation of ligation procedures in mammals. The said curved suture applicator enables a surgeon to efficiently encircle a target tissue such as a blood vessel with a suture or thread. A kit is also provided, comprising the said curved suture applicator, an appropriate length of suture or thread, and a suture manipulation device, such as a pair of forceps. Furthermore, a minimally invasive ligation method is provided that utilizes the said curved suture applicator and kit to efficiently band the transverse aorta of small mammals. Such banding is useful in studying and simulating the effects of left ventricular hypertrophy as it relates to congenital heart failure.
