| 20080277570 | HIGH PRECISION COMPACT ROTATION ANGLE ABSOLUTE ENCODER - An angle absolute encoder comprises a code rod encoded with code marks configured in segments, such that each successive segment has an increasing number of code marks, arranged at an angle to the rotation axis depending on the number of code marks in each segment. The angle of the code mark is determined by the number of code marks in the respective segment, the width of the segment parallel to the rotation axis of the code rod and the radius of the code rod. The angular resolution increases according to the number of code marks in each segment. Light is reflected from or transmitted through the code marks and detected by a light detector to determine absolute angle position. | 11-13-2008 |

| 20090285583 | SNR ENHANCEMENT IN MODULATING RETROREFLECTOR OPTICAL COMMUNICATION LINKS - An optical communication system may include a light transmission unit transmitting a light beam having a first polarization, a quarter waveplate to receive the light beam and to modify the light beam to have a second polarization, and a retroreflector to receive the light beam from the quarter waveplate and reflect the light beam to the quarter waveplate, which modifies the light beam to have a third polarization. The optical communication system may also include a half waveplate to modify the first polarization such that the first polarization is about 90 degrees rotated compared to the third polarization, and a polarizer to pass the light beam having the third polarization and to block most of the light beam having the first polarization. | 11-19-2009 |
| 20100230577 | OPTICAL ANGLE OF ARRIVAL MEASUREMENT SYSTEM AND METHOD - An optical angle of arrival measurement system uses an optical element to form at least one narrow width line on a focal plane array (FPA) which is oblique with respect to the FPA's row and column axes and which traverses at least two rows or columns along its length; forming two perpendicular narrow width lines in a cross-pattern is preferred. Interpolating the position of the lines on the FPA provides coordinates that can be used to calculate the optical angle of arrival in accordance with θx=A(x)·tan | 09-16-2010 |
| 20110079703 | OBJECT TRACKING SYSTEM - An optical tracking system comprises an array of point source emitters that output respective optical emissions, and a plurality of angle of arrival sensors. Each sensor comprises one or more optical elements and a focal plane array (FPA), with the optical elements arranged to resolve the optical emissions into one or more linear patterns on the FPA. A processing system in communication with the sensors establishes the orientation and position of each of the optical emitters using the linear patterns. A headgear tracking system employs point source emitters on a piece of headgear, with front and rear arrays of angle of arrival sensors located in an aircraft cockpit; a processing system in communication with the sensor arrays establishes an orientation and position for each of the optical emitters on the headgear. | 04-07-2011 |

| 20090006955 | METHOD, APPARATUS, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR SELECTIVELY AND INTERACTIVELY DOWNLOADING A MEDIA ITEM - An apparatus, method, system and computer program product are provided for selectively and interactively downloading a media item, such as a video. Prior to downloading the media item, the user may first download an approximation of each group of pictures (GOPs) of the video. The user can then browse through the approximations to determine which of the GOPs to download. Each approximation may include at least part of the intra frame (“I-frame”) of the corresponding GOP. In particular, the approximation may include, only the low-frequency, component of the I-frame or the I-frame itself. Once downloaded, the approximations may be displayed, and the user may select one or more of the approximations to selectively download the corresponding GOPs. The selected GOPs may thereafter be downloaded in accordance with a selected level of specificity or detail. | 01-01-2009 |
