    摘要: Integrated antenna apparatus for determination of the location of an observer and/or of the time of observation by use of a GPS or a GLONASS or other Satellite Positioning System that uses differential corrections of the pseudorange, the location and/or the observation time. The apparatus includes an antenna module and a display module, connected by a communication link. In one embodiment, the antenna module includes: a GPS antenna to receive the GPS signals; a signal frequency downconverter; a Differential GPS (DGPS) radiowave signal antenna and receiver to receive GPS correction information; a GPS/DGPS signal processor to receive the GPS antenna and DGPS antenna output signals and to determine at least one of (i) the present GPS antenna location, as corrected by the DGPS signals, and (ii) the observation time of such location; and a communication link to communicate GPS processor output signals to the display unit. The display module in this embodiment includes: a display processor to receive signals from the communication link and to process these signals for display of location or time information; and display means to visibly or audibly display the location or time information. In other embodiments, these components are repositioned. The communication link may be one or more cables or wires or may be a wireless link.

    摘要: Systems and methods are described that relate to quantum dot (QD) structures for lighting applications. In particular, quantum dots and quantum dot containing inks (comprising mixtures of different wavelength quantum dots) are synthesized for desired optical properties and integrated with an LED source to create a trichromatic white light source. The LED source may be integrated with the quantum dots in a variety of ways, including through the use of a small capillary filled with quantum dot containing ink or a quantum dot containing film placed appropriately within the optical system. These systems may result in improved displays characterized by higher color gamuts, lower power consumption, and reduced cost.

    摘要: A GNSS receiver and method using alternating “A” and “B” time segments for a reception time length of two or more data bits. The GNSS signal in an “A” time period comprising the “A” time segments is integrated for determining “A” magnitudes corresponding to code phase increments and the GNSS signal in a “B” time period comprising the “B” time segments is integrated for determining “B” magnitudes corresponding to code phase increments. A trial-and-error data bit search is performed for depolarizing data bit senses. The code phase increment showing the largest correlation level is used for acquisition of the GNSS signal and/or determination of the location where the GNSS is being received.

    摘要: An antenna aiming method and apparatus for automatically pointing an antenna to a selected distant location. The antenna aiming apparatus includes a database for storing data for distant locations, an electronic compass for determining a reference azimuth for the local antenna, and a global positioning system (GPS) receiver for determining a local location. A processor computes a pointing direction having an azimuth and an elevation from the local location to the distant location and then computes a horizontal rotation angle between the pointing direction and the reference azimuth and a vertical rotation angle from horizontal to the elevation. An antenna rotator servo-mechanism under processor control rotates the local antenna by the horizontal and vertical rotation angles for pointing the local antenna to the distant location. Optionally, the apparatus further includes electronic roll and pitch inclinometers for providing information to the processor for correcting the horizontal and vertical rotation angles for pitch and roll of the platform.

    摘要: An antenna comprises a base plate forming a ground plane, a coaxial feed serving as a mast connected to the base plate and extending along an axis that is normal to the ground plane, and two orthogonal dipoles each formed of two elements. Each dipole element has a first end connected to and supported by the mast at a first location spaced apart from the ground plane by a predetermined distance and a second end closer to the ground plane and exhibits a curvature in a plane containing the mast.
