Publication number: 20030052817Abstract: A method and apparatus for computing GPS receiver position without using absolute time information transmitted by the satellite or by an alternative source of timing available at the GPS receiver.

The first sub-array of array comprises of spaced linear radiating elements such as dipoles, log-periodic, Yagi, slotted-waveguide, patch, or array consisting of the same or different elements as used in the first sub-array, either on the same or an entirely different frequency band. Independent beam shaping systems are shown for independent operation of the two arrays.Type: ApplicationFiled: September 11, 2002Publication date: March 20, 2003Applicant: Metawave Communications CorporationInventors: Shimon B.

Publication number: 20030052829Abstract: A reflector for use under a radome disposed on a mobile platform such as an aircraft for reflecting a portion of the electromagnetic energy radiated by an antenna disposed under the radome such that the reflected portion of energy impinges the radome at an angle normal thereto, thereby reducing or eliminating further reflections of the reflected portion of energy within the radome toward the mobile platform on which the radome is mounted. In one preferred embodiment the radome includes a base portion which is covered with a cover of radar absorbing material (RAM). In another embodiment the radome includes a curved base portion which is adapted to match the curvature of the surface of the mobile platform on which the reflector is mounted.Type: ApplicationFiled: September 14, 2001Publication date: March 20, 2003Inventors: Glen J.

Publication number: 20030052830Abstract: An antenna for linearly polarized wave is accommodated in a case in which a heat sink is provided. By rotating the case depending on the vertically polarized wave or the horizontally polarized wave, wireless communication or broadcasting using the vertically polarized wave or the horizontally polarized wave can be selectively realized with high precision.Type: ApplicationFiled: March 22, 2002Publication date: March 20, 2003Inventors: Takaya Ogawa, Satoru Inagaki, Yoshiyuki Ikuma

Publication number: 20030052831Abstract: A hog-horn antenna for producing two orthogonally polarized signals. The elevation plane pattern of each signal can be made to have virtually any shape, but is typically of a substantially cosecant-squared shape. In providing for the dual-polarization capability, the hog-horn antenna is designed to produce substantially equal gains for orthogonal polarizations, either simultaneously or separately. Two techniques to substantially equate the elevation plane radiation patterns of the two polarizations include corrugating or absorber-lining the surfaces of portions of the hog-horn antenna. Azimuthal pattern control may be achieved by corrugated/absorber lined flanges.Type: ApplicationFiled: September 20, 2001Publication date: March 20, 2003Applicant: Andrew CorporationInventors: Charles M.

Publication number: 20030052832Abstract: A signal sensing module senses an RF signal and produces one or more secondary signals representative of the RF signal. An impedance matching control module generates a control signal, based on the one or more secondary signals, which is indicative of an impedance mismatch between a load and a communications device. The control signal is then applied to at least one variable impedance device to adjust the impedance of an impedance matching network and thereby reduce the impedance mismatch between the load and the communications device. In an embodiment, the at least one variable impedance device is a barium strontium titanate, thin film, parallel plate capacitor. In other embodiments, other variable impedance devices such as other types of thin film capacitors or varactor diodes are be used to adjust the impedance of the impedance matching network.Type: ApplicationFiled: August 24, 2001Publication date: March 20, 2003Applicant: Broadcom CorporationInventors: Nicolaos G.

Publication number: 20030052834Abstract: An antenna system for receiving both circularly polarized electromagnetic signals and linearly polarized electromagnetic signals, the circularly polarize signals arriving at the antenna system from a direction normal or oblique to a major surface of the antenna system and the linearly polarized signals arriving at the planar antenna system from a direction acute to said major surface. The antenna system includes a high impedance surface and a plurality of antenna elements disposed on said high impedance surface, the plurality antenna elements arranged in a pattern on said surface such first selected ones of said antenna elements are responsive to circular polarization and second selected ones of said antenna elements are responsive to linear polarization.Type: ApplicationFiled: July 13, 2001Publication date: March 20, 2003Applicant: HRL Laboratories, LLCInventors: Daniel F.

Publication number: 20030052835Abstract: A method of presenting information to an audience. The method includes the step of determining the specific information which the presenter desires to convey to an audience. The presenter determines an organizational framework on which to divide the information. The information is then chunked into groupings based on the organizational framework. Each grouping is then displayed on a specific, separate display for dissemination to the audience based on the determined organizational framework. Preferably, the information is displayed on three displays. Each grouping of information and its associated position on a display is explained to the audience for maximum effect.Type: ApplicationFiled: August 16, 2002Publication date: March 20, 2003Inventor: Stephen F.
