  • Publication number: 20220118388
    Abstract: An apparatus and related methods to separate liquid from a liquid/gas mixture, particularly in a low gravity environment. The apparatus includes a chamber having a capillary channel around a perimeter of the chamber, a liquid/gas inlet to the chamber, a liquid outlet from the chamber, the liquid outlet being positioned at the perimeter of the chamber to remove liquid from the capillary channel, and a gas outlet from the chamber. The gas outlet is positioned in the chamber, away from the capillary channel, to remove gas from the chamber. The chamber is structured to be readily fabricated using traditional machining techniques or additive manufacturing techniques. The chamber may be fabricated from various materials, including, for example, polymers, metals, composites, and ceramics. The chamber may function as a heat exchanger so that the apparatus can remove condensable vapors from the gas in the mixture in addition to what is already liquid.

  • Publication number: 20210335139
    Abstract: An imaging system for a moving vehicle aggregates pre-existing data with sensor data to provide an image of the surrounding environment in real-time. The pre-existing data are combined with data from one or more 3-D sensors, and 2-D information from a camera, to create a scene model that is rendered for display. The system accepts data from a 3-D sensor, transforms the data into a 3-D data structure, fuses the pre-existing scene data with the 3-D data structure and 2-D image data from a 2-D sensor to create a combined scene model, and renders the combined scene model for display. The system may also weight aspects of data from first and second sensors to select at least one aspect from the first sensor and another aspect from the second sensor; wherein fusing the pre-existing scene data with the sensor data uses the selected aspect from the first sensor and the selected aspect from the second sensor.

  • Patent number: 11121465
    Abstract: A steerable beam antenna includes a feed line and first and second arrays of switchable scatterers along opposite sides of the feed line. The first array scatters an electromagnetic wave propagating through the feed line to form a first beam portion with a first polarization, and the second array scatters the propagating wave to form a second beam portion with a second polarization orthogonal to the first polarization. Each scatterer in the first and second arrays is switchable between a high state and a low state, the high state scatterers and the low-state scatterers in each of the first and second arrays defining a periodic pattern. The scatterers in the first and second arrays are switchable to shift the pattern of scatterers in one of the arrays relative to the pattern in the other array by a selectable period shift that yields a desired polarization for the beam.

  • Patent number: 10665939
    Abstract: A scanning antenna system includes a feed line having first and second ends, and a scanning antenna element disposed with respect to the feed line so that, in the transmit mode, a signal input to one of the first and second ends of the feed line is evanescently coupled to the antenna element, whereby the antenna element radiates the signal as a shaped beam through an angular scanning field having a negative angular scanning space and a positive angular scanning space on either side of the stop band near 0°. A switching network, operatively coupled to the feed line, switches the signal input between the first and second ends of the feed line in a controlled sequence, whereby the shaped beam radiated by the antenna element is scanned in the negative scanning space, the stop band, and the positive scanning space. The antenna system performs reciprocally in the receive mode.
