Abstract
A system and a method for detecting and determining predetermined conditions related to a human occupant in a predetermined space includes one or more microphones for receiving sounds from within the predetermined space, and for transmitting received sounds to a received sound processor. The received sound processor is responsive to the received sounds, for determining at least one predetermined condition related to human occupant in the predetermined space. The system may further include an imager, a range-finder, a calibration factor and a processor. Images are taken of a space and corrected based on the appropriate calibration factor based on the output of the range-finder. The images are analyzed and compared to characteristics representative of certain events including falls. If the images match the particular characteristics, the system concludes that an event has occurred and outputs this result. An alarm may be generated if the system detects certain events.
