SYSTEM AND METHOD FOR REMOTELY MONITORING PHYSIOLOGICAL FUNCTIONS
First Claim
1. A system for remotely monitoring an individual, the system comprising:
- a laser radar system that determines ranges and range rates of one or more points on one or more surfaces of the individual over a period of time; and
a monitor module that monitors one or more physiological functions or physical activities of the individual based on the ranges and range rates determined by the laser radar system.

Abstract
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.

7. A method of remotely monitoring an individual, the method comprising:
-
emitting a beam of radiation sequentially toward one or more points on one or more surfaces of the individual; receiving a portion of the beam of radiation reflected from the points on the surfaces of the individual; determining ranges and range rates of the points on the surfaces of the individual based on one or more aspects of the beam of radiation; and monitoring one or more physiological functions or physical activities of the individual based on the ranges and range rates of the points on the surfaces of the individual. - View Dependent Claims (8, 9, 10, 11, 12)

13. A system for monitoring an individual, the system comprising:
-
a first coherent laser radar section including; a laser source that generates a first laser beam, an interferometer that splits the first laser beam into a first target beam that is directed toward the individual and a first local oscillator beam, and generates a first combined target beam from a first reflected portion of the first target beam returning from the individual and the first local oscillator beam; a second coherent laser radar section including; a laser source that generates a second laser beam, an interferometer that splits the second laser beam into a second target beam that is directed toward the individual with the first target beam and a second local oscillator beam, and generates a second combined target beam from a second reflected portion of the second target beam returning from the individual and the second local oscillator beam; a processor that determines ranges and range rates of one or more points on one or more surfaces of the individual over a period of time from the first combined target beam and the second combined target beam, and wherein the processor monitors one or more physiological functions or physical activities of the individual based on the ranges and range rates determined by the processor. - View Dependent Claims (14, 15, 16, 17, 18)
