    摘要： A rigid coupler for use in electrically isolating an electrically conductive fluid conveyance system is described. The rigid coupler includes a nonconductive liner having a first end configured to couple to a first adjoining section of the fluid conveyance system, and a second end, opposite said first end, configured to couple to a second adjoining section of the fluid conveyance system. A reinforcing structure circumscribes the nonconductive liner and is coupled to a portion of the nonconductive liner extending between the first and second ends of the nonconductive liner. The reinforcing structure includes a multi-axial braided fiber material impregnated with a matrix material. A fiber overwrap is hoop wound about at a least a portion of the reinforcing structure between the first and second ends of the nonconductive liner.

    摘要： A time of flight (TOF) camera comprises a light source for illuminating an object with light and a plurality of light-sensitive pixels for collecting return image light reflected by the object. Further, each light-sensitive pixel of the TOF camera may comprise a photoelectric cathode for generating electrons responsive to return image light incident on the pixel and a plurality of anodes for collecting electrons generated at the photoelectric cathode.

    摘要： An eye movement tracking device that can be mounted to standard eyeglasses as disclosed. The device comprises an illumination source, a time-of-flight (TOF) camera and a processor. The source transmits energy within a frequency band from a location proximate to an eye of a person, such that at least a first portion of the transmitted energy is reflected off a lens of eyewear worn by the person to subsequently reflect off the eye, and such that at least a second portion of the transmitted energy is transmitted through the lens to reflect off objects in the person's environment. The TOF camera detects reflections of at least the first portion of the transmitted energy, and distinguishes them from other energy detected by the TOF camera in said frequency band, based on TOF principles. The processor uses the detected reflections of the first portion of the transmitted energy to determine eye position.

    摘要： A broadband imager, which is able to image both IR and visible light, is disclosed. In one embodiment, an IR sensitive region of an IR pixel underlies the R, G, B sensitive regions of R, G, and B visible pixels. Therefore, the IR pixel receives IR light through a same surface area of the photosensor through which the R, G, and B pixels receive visible light. However, the IR light generates electron-hole pairs deeper below the common surface area shared by the RGB and IR pixels, than visible light. The photosensor also has a charge accumulation region for accumulating charges generated in the IR sensitive region and an electrode above the charge accumulation region for providing a voltage to accumulate the charges generated in the IR pixel.
