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 configured to;
direct a first beam of radiation and a second beam of radiation to each of one or more points on the skin or the clothing of the individual, wherein the first beam of radiation is modulated by a first chirp rate,combine a reflected portion of the first beam of radiation with a reflected portion of the second beam of radiation to determine a range and an instantaneous velocity for each of the one or more points on the skin or the clothing of the individual over a period of time, wherein each of the respective reflected portions are reflected from the one or more points on the skin or the clothing of the individual; and
a monitor module that monitors one or more physiological functions or physical activities of the individual based on the ranges and the instantaneous velocities 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.

9. A method of remotely monitoring an individual, the method comprising:
-
emitting a first beam of radiation and a second beam of radiation toward one or more points on the skin or the clothing of the individual, wherein the first beam of radiation is modulated by a first chirp rate; receiving a portion of the first beam of radiation and a portion of the second beam of radiation, wherein each of the respective portions are reflected from the one or more points on the skin or the clothing of the individual; combining the received portion of the first beam of radiation with the received portion of the second beam of radiation to form a combined signal; determining, using a processor, a range and an instantaneous velocity for each of the points on the skin or the clothing of the individual based on the combined signal; and monitoring, using a processor, one or more physiological functions or physical activities of the individual based on the ranges and the instantaneous velocities of the points on the skin or the clothing of the individual. - View Dependent Claims (10, 11, 12, 13, 14)
