摘要:
A rotary hinge assembly (100) includes a hinge housing (104) including at least one interior chamber. A spring (160) disposed within the hinge housing (104) provides a torque on an attached door while in an opened and closed position. A rotor (130) rotatably disposed within the at least one interior chamber includes at least one rotor vane (134) that moves in relation to a stationarily mounted stator (120) having at least one stator vane (124). A fill plug (140) includes a plurality of entrance and exit holes disposed in relation to the stator and rotor vanes (124, 134) to define a fluidic damper assembly. A valve (180) disposed within the fill plug (140) permits selective adjustment of the fluidic damper by restricting or opening the entrance and exit holes of the fill plug (140).
摘要:
A monolithic electronic chip including a substrate (100) having first and second opposing surfaces with a first circuit portion (210) disposed on at least one of the first or second opposing surfaces and a first circuit (102) formed on the first circuit portion of the substrate; a second circuit portion (212) disposed on at least one of the first or second opposing surfaces; and a second circuit (104) formed on the second circuit portion of the substrate. At least one through-hole (201) extending from the first surface to the second surface with at least one conductive impedance tap (200, 214). Each conductive impedance tap is formed within one of the at least one through-hole (201) in the substrate and coupled to a surface of that through-hole to electrically couple the substrate to a reference voltage (202). Tthe first impedance (204) between the first circuit (102) and the reference voltage (202) via the at least one conductive impedance tap (200, 214) is less than a first-second crosstalk impedance (106) between the first circuit and the second circuit via the substrate (100) and a second impedance (206) between the second circuit (104) and the reference voltage (202) via the at least one conductive impedance tap (200, 241) is less than the first-second crosstalk impedance (106).

An image intensifier tube includes a microchannel plate (MCP) (94) having conductive input and output surfaces disposed in a housing. A conductive lower support (92) is in electrical contact with the output surface of the MCP, and a conductive upper support (91) is disposed above the input surface of the MCP. A shape memory alloy (SMA) lockdown (93,96) is disposed between the input surface of the MCP and the upper support. The SMA lockdown is configured to provide a lockdown for the MCP in the housing. An SMA upper surface (93A,96A) is configured to provide an axial force against the upper support, and an SMA lower surface (93C,96C) is in contact with the input surface of the MCP.

A method of performing Raman spectroscopy, and an apparatus for performing the method, including irradiating, with laser light, a trace amount of a target substance disposed on a painted surface, receiving reflected laser light and a Raman return signal from the trace amount of the target substance, processing the Raman return signal using, at least, a spectrograph (100) and camera (110) to obtain a Raman signature for the target substance, and identifying the target substance based on the Raman signature for the target substance and a database of Raman signatures. The laser light wavelength is selected based on a ratio of Raman return signal power to fluorescence power.

摘要:
A technique for simultaneously transmitting wide and narrow optical beacon signals includes generating a laser beam and splitting the laser beam into a first signal on a first path and a second signal on a second path via a wavelength-dependent beamsplitter. A wide beacon signal having a first beam divergence is generated from the first signal, and a narrow beacon signal having a second, lesser beam divergence is generated from the second signal. The wavelength of the laser beam determines an allocation of the laser energy between the wide and narrow beacon signals based on transmittance/reflectance characteristic of the beamsplitter at that wavelength. The wide and narrow beacon signals are simultaneously transmitted in a overlaid manner into free space to support acquisition and tracking in a free-space optical communication system. The beamsplitter can simultaneously transmit or reflect substantially all of a data signal at a different wavelength.
