20090216093 | SYSTEM AND METHOD FOR REMOTELY MONITORING PHYSIOLOGICAL FUNCTIONS - A system and method for remotely monitoring an individual, in accordance with some embodiments of the invention. More particularly, one or more physiological functions and/or physical activities of the individual may be monitored. In order to monitor the individual, a range to, and/or a range rate (i.e., velocity) of, one or more points on one or more surfaces of the individual (e.g., skin, clothing, lips, etc.) may be determined over time. Based on the determinations of the range and/or range rate of the points on the surfaces of the individual, the one or more physiological functions and/or physical activities of the individual may be monitored. This may enable the physiological functions and/or physical activities to be monitored remotely from the individual without access or proximity to the individual. | 08-27-2009 |
20100201945 | SYSTEM AND METHOD FOR TRACKING EYEBALL MOTION - Detecting position information related to a face, and more particularly to an eyeball in a face, using a detection and ranging system, such as a Radio Detection And Ranging (“RADAR”) system, or a Light Detection And Ranging (“LIDAR”) system. The position information may include a location of the eyeball, translational motion information related to the eyeball (e.g., displacement, velocity, acceleration, jerk, etc.), rotational motion information related to the eyeball (e.g., rotational displacement, rotational velocity, rotational acceleration, etc.) as the eyeball rotates within its socket. | 08-12-2010 |

20140139818 | Chirped Coherent Laser Radar System and Method - A laser radar system using collocated laser beams to unambiguously detects a range of a target and a range rate at which the target is moving relative to the laser radar system. Another aspect of various embodiments of the invention may relate to a laser radar system that uses multiple laser radar sections to obtain multiple simultaneous measurements (or substantially so), whereby both range and range rate can be determined without various temporal effects introduced by systems employing single laser sections taking sequential measurements. In addition, other aspects of various embodiments of the invention may enable faster determination of the range and rate of the target, a more accurate determination of the range and rate of the target, and/or may provide other advantages. | 05-22-2014 |
20140268290 | SYSTEM AND METHOD FOR INCREASING COHERENCE LENGTH IN LIDAR SYSTEMS - Various implementations of the invention compensate for “phase wandering” in tunable laser sources. Phase wandering may negatively impact a performance of a lidar system that employ such laser sources, typically by reducing a coherence length/range of the lidar system, an effective bandwidth of the lidar system, a sensitivity of the lidar system, etc. Some implementations of the invention compensate for phase wandering near the laser source and before the output of the laser is directed toward a target. Some implementations of the invention compensate for phase wandering in the target signal (i.e., the output of the laser that is incident on and reflected back from the target). Some implementations of the invention compensate for phase wandering at the laser source and in the target signal. | 09-18-2014 |
