  • Patent number: 11485937
    Abstract: The present invention is directed to a cleaning composition for sanitizing or disinfecting hard surfaces containing a cationic biocide, surfactant and low levels of VOC solvents. The cleaning composition is adapted to clean a variety of hard surfaces without leaving behind a visible residue and creates low levels of streaking and filming on the treated surface. The cleaning composition contains less than 5% by weight of VOCs. The cleaning composition may be used alone as a liquid or spray formulation or in combination with a substrate, for example, a pre-loaded cleaning wipe.

  • Patent number: 11459843
    Abstract: A space-out mechanism that may be used in a tubing hanger system to install a tubing hanger and rigidize the tubing hanger and a casing hanger within a wellhead housing in a single trip is provided. The space-out mechanism may include two pieces that are configured to rotate against each other such that the axial length of the space-out mechanism can be adjusted to remove any axial gaps created in the installation of the tubing hanger or rigidizing of the tubing hanger and casing hanger within the wellhead housing. The two pieces of the space-out mechanism may include a ramp ring and a piston. The ramp ring and piston may each have ramp surfaces that rotate and bear against each other until the system is rigidized.

  • Patent number: 11456534
    Abstract: A multi-band antenna includes an S-band substrate; an S-band annular ring on the S-band substrate; an X-band substrate in the S-band substrate; and an X-band patch located in a center of the S-band annular ring and on the X-band substrate. The S-band annular ring includes a first upper surface, the X-band patch includes a second upper surface, and the first upper surface is planar with the second upper surface. The multi-band antenna includes a second pair of concentric patch antennas arranged in an annular configuration and stacked on the first pair of antennas. The second pair of antennas are placed on the same substrate and are electromagnetically coupled to the first pair of antennas to provide an extended bandwidth capability.

  • Patent number: 11435229
    Abstract: Shortwave infrared (SWIR) hyperspectral imaging (HSI) systems comprise a supercontinuum laser source configured to illuminate objects and a receiver comprising a spectrometer configured to receive light reflected from the objects. In some cases, hyperspectral images can be created by raster scanning of the source/receiver across a scene. The supercontinuum laser source provides active illumination to allow collection of hyperspectral imagery during day (including overcast conditions) and night. Additionally, the hyperspectral imaging systems can use range-gated imaging.

  • Patent number: 9912060
    Abstract: Embodiments of present inventions relate to low-profile, tapered cavity broadband antennas. One important aspect of the invention (although not the only) is the incorporation of a tapered lateral sidewalls in the antenna cavity. More particularly, according to various embodiments, a low-profile, tapered cavity antenna may comprise: an aperture defining an opening to a cavity; and an interior space defined by the cavity which is formed of a flat bottom wall defining a ground plane, and a pair of spaced-apart, tapered lateral sidewalls extending away from the flat bottom wall in opposite directions toward the aperture. The tapered shape of the tapered lateral sidewalls are specifically configured to maintain a constant resonance frequency within the cavity. In some embodiments, an isotropic high index medium material is at least partially loaded within the tapered cavity. Also, antenna may include a single or two-input port.

    Abstract: Embodiments of the present invention relate to low-profile broadband antennas having an anisotropic traverse resonance condition. One important aspect of the invention is the incorporation of an anisotropic high index medium material, at least partially loaded within the cavity, which is configured to maintain a constant resonance frequency of the antenna. A low-profile cavity antenna may comprise: an aperture defining an opening to a cavity; an interior space defined by the cavity which is formed of a flat bottom wall defining a ground plane, and a pair of spaced-apart, lateral sidewalls extending away from the flat bottom wall in opposite directions toward the aperture; and an anisotropic high index medium material, at least partially loaded within the cavity, configured to maintain a constant resonance frequency of the antenna. The lateral sidewalls may extend from opposing sides of the flat bottom wall perpendicularly or with an outwardly taper.

  • Patent number: 9152602
    Abstract: A pseudo-agent is disclosed herein that bridges this divide. For purposes of the discussion herein, a pseudo-agent is a machine that is installed on a fully capable host machine, such as a Windows or UNIX machine, and that gathers and evaluates content from a management server, takes actions if so instructed, and reports the results of its evaluation upstream. However, unlike an agent in a traditional management system, which inspects and acts on the local machine, the pseudo-agent actually inspects and acts on a remote device, or many remote devices.

  • Patent number: 8089747
    Abstract: A power pedestal provides power to a vehicle and a structure disposed separate from the vehicle. The power pedestal includes a housing having an exterior, a first end fixed to a platform, and a second end disposed opposite and distal from the first end. A meter socket assembly is housed by the housing. At least one first branch circuit breaker and a second main circuit breaker are electrically connected to the meter socket assembly within the housing. At least one of the at least one first branch circuit breaker is electrically connected to the vehicle by a corresponding one of a number of first electrical conductors. The second main circuit breaker is electrically connected to the structure by a second electrical conductor. A meter, which is electrically connected to the meter socket assembly, measures electric energy consumed by the vehicle and the structure.
