20140125986 | OCT system with tunable clock system for flexible data acquisition - An OCT system and particularly its clock system generates a k-clock signal but also generates an optical frequency reference sweep signal that, for example, indicates the start of the sweep or an absolute frequency reference associated with the sweep at least for the purposes of sampling of the interference signal and/or processing of that interference signal into the OCT images. The clock system is also tunable to allow the control or flexibility over the relationship between the scanning of the swept optical signal and the sampling of the interference signal by the data acquisition system. Specifically, the absolute frequencies of the swept optical signal at which the k-clock signals are generated can be adjusted. Also, the absolute frequency of the swept optical signal at which sampling of the interference signal is initiated can also be changed or stabilized. Moreover, optical frequency sampling interval defined by the k-clock signal can be changed under user control or simply stabilized. | 05-08-2014 |
20140125991 | OCT system with phase sensitive interference signal sampling - An OCT system and particularly its clock system generates a k-clock signal but also generates an optical frequency reference sweep signal that, for example, indicates the start of the sweep or an absolute frequency reference associated with the sweep at least for the purposes of sampling of the interference signal and/or processing of that interference signal into the OCT images. This optical frequency reference sweep signal is generated at exactly the same frequency of the swept optical signal from sweep to sweep of that signal. This ensures that the sampling of the interference signal occurs at the same frequencies, sweep to sweep. Such a system is relevant to a number of applications in which it is important that successive sweeps of the swept optical signal be very stable with respect to each other. One specific example is phase sensitive OCT. This requires that the sampling of the interference signal occurs at exactly the same frequency/wavelength on every axial line (A-line). Such phase sensitive OCT has particular applications in Doppler OCT, synthetic aperture imaging, and in the subtraction of background noise sources from the OCT image. | 05-08-2014 |

This allows for a separate electrostatic cavity, that is outside the laser's optical resonant cavity. Moreover, the use of this cavity configuration allows the MEMS mirror to be tuned by pulling the mirror away from the active region. This reduces the risk of snap down. Moreover, since the MEMS mirror is now bonded to the active region, much wider latitude is available in the technologies that are used to fabricate the MEMS mirror. This is preferably deployed as a swept source in an optical coherence tomography (OCT) system. | 06-26-2014 |
20140218741 | OCT Swept Laser with Cavity Length Compensation - An optical coherence tomography system utilizes an optical swept laser that has cavity length compensator that changes an optical length of the laser cavity for different optical frequencies to increase the length of the laser cavity for lower optical frequencies.

20120120372 | SYSTEM AND METHOD FOR CALIBRATING A DISPLAY SYSTEM USING MANUAL AND SEMI-MANUAL TECHNIQUES - The invention provides a system and method that reduces the tediousness of the manual alignment process. Users select correspondences between projectors or components of a projector, to form a common coordinate. Using models of the display system, and projectors, the common coordinate system can be mapped quickly to the entire display. The process avoids a need to measure screen points, and allows the user to move significantly fewer points. Alternatively, the invention allows introduction of machine-vision style algorithms into manual calibration techniques to improve performance. This overcomes the tediousness of prior systems by introducing models of the display into the manual alignment process, allowing selection of a small number of points on each projector, and avoiding selection of precisely measured screen points.

20100228407 | METHOD OF DETERMINING AND CONTROLLING THE INERTIAL ATTITUDE OF A SPINNING, ARTIFICIAL SATELLITE AND SYSTEMS THEREFOR - A method of and apparatus for determining and controlling the inertial attitude of a spinning artificial satellite without using a suite of inertial gyroscopes. The method and apparatus operate by tracking three astronomical objects near the Earth's ecliptic pole and the satellite's and/or star tracker's spin axis and processing the track information.

20110297794 | METHOD OF NAVIGATING A SPINNING, ARTIFICIAL SATELLITE AND CONTROLLING THE GLOBAL, TERRESTRIAL SURVEILLANCE COVERAGE THEREOF - A method of controlling inertial attitude of an artificial satellite in order to perform a navigation function and to maximize terrestrial coverage of the Earth by the satellite. The method includes deploying the artificial satellite in an orbit about the poles of the Earth; applying gyroscopic precession to the artificial satellite spin axis to precess and maintain the satellite near the ecliptic pole; deploying the artificial satellite so that the spin axis is initially perpendicular to or substantially perpendicular to sun lines; and applying gyroscopic precession to the artificial satellite spin axis to precess the spin axis away from an initial deployed attitude at a selectively-variable precession rate and to maintain the spin axis perpendicular to or substantially perpendicular to a the sun lines. | 12-08-2011 |
20130101293 | World-wide, wide-band, low-latency, mobile internet and system therefor - A communication system for providing world-wide, mobile Internet communication to a plurality of users and a method therefore. The system includes ground-based, multi-channel, radio frequency transmitting and receiving broadcasting grids that are capable of providing content to multiple users via cell towers and low-altitude, optical transmitting and receiving satellites that are in optical communication with the ground-based, multi-channel, RF transmitting and receiving broadcasting grids. The method includes transmitting optical and/or RF signals between at least one of the ground-based, multi-channel, RF transmitting and receiving broadcasting grids and at least one of the low-altitude, optical transmitting and receiving satellites. | 04-25-2013 |
