Wireless drink container for monitoring hydration
First Claim
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;
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; and
an antenna, operably coupled to the processor, to transmit an indication of the change in the level of the liquid in the cavity to a wireless device.

Abstract
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.

16. A method of tracking consumption, by a user, of a liquid disposed within a container, the method comprising:
-
(A) measuring, with an accelerometer mechanically coupled to the container, an acceleration of the container; (B) estimating, with a processor operably coupled to the accelerometer, an orientation of the container based on the acceleration; (C) determining if the orientation is within a predefined range of orientations; (D) in response to determining that the orientation is within the predefined range of orientations, measuring, with a liquid level sensor operably coupled to the processor, a level of the liquid in the container; (E) estimating a change in the level of the liquid in the cavity based on the level of the liquid in the cavity; (F) transmitting, via an antenna operably coupled to the processor, an indication of the change in the level of the liquid in the container to a wireless device; and (G) emitting light from a light source operably coupled to the processor and disposed in the container, the light prompting the user to drink at least some of the liquid in the container. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A container assembly comprising:
-
a translucent container to hold a liquid; a substrate extending at least partway into the liquid; a liquid level sensor, disposed on the substrate, to measure a level of the liquid; an accelerometer, mechanically coupled to the translucent container, to measure an acceleration of the translucent container; a processor, operably coupled to the accelerometer and the liquid level sensor, to (i) periodically determine an orientation of the translucent container based on acceleration measured by the accelerometer and (ii) periodically determine a change in the level of the liquid in the cavity based on the level of the liquid measured by the liquid level sensor and the orientation of the translucent container; an antenna, operably coupled to the processor, to transmit the change in the level of the liquid to a wireless device; and a light source, disposed on the substrate and operably coupled to the processor, to emit light (i) at periodic intervals and (ii) in response to a command received from the wireless device via the antenna, wherein the command is based on (i) a comparison of the change in the level of the liquid and a desired change in the level of the liquid and (ii) a time since a last emission of light from the light source.
