WIRELESS DRINK CONTAINER FOR MONITORING HYDRATION
A wireless drink container can monitor a person's hydration and prompt him or her to drink more if appropriate. The drink containers as described herein can monitor liquid levels and communicate with external devices about the liquid levels and rate of consumption. One or more sensors in the drink container monitor the liquid level within the container. A processor coupled to the sensor(s) estimates how much liquid has been removed from the container from changes in the liquid level and transmits a signal representing the change in liquid level to a smartphone or other external device. It also triggers an audio or visual indicator, such as an LED, that prompts the user to drink more based on the user's estimated liquid consumption and on the user's liquid consumption goals, which may be based on the user's physiology, activity level, and location.
1 . A container assembly comprising:
a container defining a cavity to hold a liquid;
a liquid level sensor, disposed in the cavity, to measure a level of the liquid in the cavity;
a processor, operably coupled to the liquid level sensor, to poll the liquid level sensor for a measurement of the level of the liquid in the cavity and to estimate a change in the level of the liquid in the cavity based on the measurement of the level of the liquid in the cavity; and
a visual indicator, operably coupled to the processor and disposed within the cavity, to provide a visual indication prompting a user to drink from the container.
