  • Patent number: 9635223
    Abstract: A telescope system may facilitate the capture of images of light, and may have a housing, a primary mirror, a Schmidt corrector plate, and a lens group. The housing may have a mirror end and an aperture end with an entrance aperture that receives the light. The primary mirror may be positioned proximate the mirror end, and may have a spherical shape. The Schmidt corrector plate may be positioned proximate the entrance aperture to direct the light toward the primary mirror in a manner that substantially compensates for the spherical shape. The lens group may include multiple lenses, one or more of which may be positioned within the housing proximate the aperture end such that the light is directed through the lens group by the primary mirror. The lens group may focus the light at a focal location further than the Schmidt corrector plate from the primary mirror.

  • Patent number: 9533936
    Abstract: An esterified propoxylated glycerin process is improved by the incorporation of a vacuum distillation step whereby unreacted fatty acids are removed in a form suitable for direct reuse in a further esterification. The esterified propoxylated glycerin produced is low in color and has a low content of free fatty acid, making it suitable for use as a reduced calorie fat substitute in various food products.

  • Patent number: 8705546
    Abstract: A redundancy switch includes at least three data ports and a control input. Each data port includes a data input and a data output. The redundancy switch operates in one of at least three states. In a first state, a first data port is communicatively coupled with a second data port. In a second state, the first data port is communicatively coupled with a third data port. In a third state, the second data port is communicatively coupled with the third data port. The state of the redundancy switch can be controlled based on a signal received at the control input. The redundancy switch can further include transconductance switching elements that convert a voltage input to a current output.

    Abstract: Examples of circuits and methods are provided for common mode stability and bandwidth broadening. A current generator circuit may include a first and a second transistor. Each of the first and second transistors includes a first, second, and third terminal. The first and second transistors provide a first and a second output current at their corresponding third terminals. A first branch including a first resistor and a first capacitor coupled in series is coupled between the third terminal of the first transistor and the first terminal of the second transistor. A second branch including a second resistor and a second capacitor coupled in series is coupled between the third terminal of the second transistor and the first terminal of the first transistor. The first and the second branches are configured to enable the current generator circuit to provide the first and second currents with improved common mode stability.

  • Patent number: 8401307
    Abstract: A plate solving methodology determines celestial coordinates of an image. Star locations are extracted from the image in terms of pixel coordinates. A group of four stars, referred to as a “test quad”, is identified. A signature for the test quad is generated. In one embodiment, this test signature is derived by determining the separations of the four stars in the test quad, normalized by the largest separation. In one embodiment, the signature also includes the sum of these normalized separations. A query is performed, using the generated signature, against a database of reference signatures for known groups of stars (referred to as “reference quads”). A geometric transform is determined, establishing the relationship between the test quad and a reference quad that matches within a specified tolerance. This geometric transform defines the celestial coordinates of the image. Additional verification steps can be performed to confirm the accuracy of the match.
