Abstract: At least some aspects of the present disclosure direct to systems and methods for monitoring a physiological condition with a plurality of sensors. The system includes a wireless adaptor device and a wireless sensor device. The wireless adaptor device is configured to transmit wireless identification of the wireless adaptor device to the wireless sensor device via a NFC communication. The wireless sensor device is configured establish a wireless communication with the wireless adaptor device using the wireless identification of the wireless adaptor device. The wireless sensor device is further configured to transmit sensor signals to the wireless adaptor device via the established wireless communication.

Abstract: The controller of the plural component proportioner (10) dispenses both components (or all three if a three component material) as necessary to maintain the correct mix ratio. The fluid displacement measuring technique described allows this proportioning to take place with the “A” or main component pump always able to supply fluid to the spray gun without being stopped. The “B” component, at a higher pressure, is added as necessary to control ratio. The control can determine whether the pumps were properly loaded with fluid, and the fluid was properly compressed for accurate measurement. This technique allows for the proportioned fluids to be provided to the spray gun(s) at high flow rates and consistent spray pressure without interruption.
