Abstract
An apparatus detects and measures vital signs of each human target by a continuous, non-intrusive method. In an example, the vital signs of interest include a heart rate and a respiratory rate, which can provide valuable information about the human's wellness. Additionally, the heart rate and respiratory rate can also be used to identify a particular person, if more than two target humans are living in a home. The apparatus has a natural convection spatial flow path that draws heat from at least one processor, one fan-less radar and a heat sink.
Claims20
An apparatus for person monitoring, comprising:
- a housing having an inner region and an exterior region enclosing the inner region;
- a plurality of openings configured on the exterior region and that communicate with the inner region;
- radio frequency (RF) components including an RF transmit antenna coupled to an RF generator and an RF receive antenna coupled to an RF receiver, the RF transmit antenna configured to emit RF signals and the receive antenna configured to receive backscattered RF signals derived from the emitted RF signals, the RF components being disposed within the inner region;
- at least one processor within the inner region;
- at least one non-transitory computer-readable medium within the inner region comprising instructions to cause the at least one processor to determine a parameter associated with a status of a person based on the received backscattered RF signals;
- and
- a natural convection spatial flow path flowing from the inner region and through at least one of the plurality of openings to the exterior region to draw heat from the at least one processor and the RF components without use of a fan, thereby avoiding fan-produced noise and vibration.
A method performed by an apparatus for person monitoring, the apparatus comprising:
- a housing having an inner region and an exterior region enclosing the inner region;
- a plurality of openings configured on the exterior region that communicate with the inner region;
- radio frequency (RF) components including an RF transmit antenna coupled to an RF generator and an RF receive antenna coupled to an RF receiver, the RF transmit antenna configured to emit RF signals and the receive antenna configured to receive backscattered RF signals derived from the emitted RF signals, the RF components being disposed within the inner region;
- at least one processor within the inner region;
- a natural convection spatial flow path flowing from the inner region and through at least one of the plurality of openings to the exterior region to draw heat from the at least one processor and the RF components without use of a fan, thereby avoiding fan-produced noise and vibration;
- and
- at least one non-transitory computer-readable medium within the inner region comprising instructions to perform the method, the method comprising determining a parameter associated with a status of a person based on the received backscattered RF signals.
