| 20090023383 | Distributed conformal adaptive antenna array for SATCOM using decision direction - An apparatus comprises a distributed array of antenna elements for receiving a radio frequency signal on a satellite communications link, wherein the radio frequency signal includes a known preamble; a plurality of mixers for translating the radio frequency signal to a plurality of baseband signals having in-phase and quadrature components; a processor for applying weights to the baseband signals, wherein the weights are found adaptively in response to the preamble in combination with decision-directed feedback when the preamble is not present; and a receiver for processing the weighted baseband signals. A pre-processor can be used to create sub-arrays of the antenna elements using maximal-ratio weighting. A method performed by the apparatus is also provided. | 01-22-2009 |
| 20090146881 | MULTI-PLATFORM PRECISION PASSIVE LOCATION OF CONTINUOUS WAVE EMITTERS - An apparatus comprises a first sensor mounted on a first platform for sampling a first portion of a continuous waveform occurring in a time window and for producing a first signal sample, a second sensor mounted on a second platform for sampling a second portion of the continuous waveform occurring in the time window for producing a second signal sample, and a processor for determining time difference of arrival measurements and for applying a maximum likelihood estimation process to combine multiple time difference of arrival measurements between multiple pairs of platforms, to estimate the location of an emitter of the continuous waveform. A method performed by the apparatus is also provided. | 06-11-2009 |

| 20120003004 | Center-referenced Photoconductor Bearing Plate and Assembly for Electro-photographic Cartridge - A bearing plate for rotably supporting a photoconductor drum having a center shaft according to one exemplary embodiment includes a body having a first side, a second side, and an edge surface between the first and second sides. A center hole extends through the body for rotably receiving an end of the center shaft and positionally referencing an outer surface of the photoconductor drum to a center axis of the center hole. A support arm extends from the body in a non-radial direction. The support arm has a mounting surface for receiving an additional component positionally referenced to the center axis. An assembly for use in an image forming device according to one embodiment includes a photoconductor drum having a center shaft and a pair of substantially identical bearing plates mounted on opposite ends of the photoconductor drum. The bearing plates are translated from one another and have identical orientations. | 01-05-2012 |
