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.

Abstract: A smart container that includes a bottle or other container, a load cell, an accelerometer, a processor, and a colored light source. The container may be a liquid container, a pill container, or a food container. The colored light source may include one or more light-emitting diodes (LEDs) which can be programed to emit unique illumination patterns. The container may also include a speaker or motor to emit audio and vibrational notifications. The container provides a method of tracking consumption by a user of a substance held in a container.

Abstract: The present disclosure is directed to smart, portable, reusable liquid containers, or container assemblies, with ultraviolet (UV) sterilization capability. An example container assembly includes a container defining a cavity to hold liquid. A cap coupled to the container prevents the liquid from spilling out of the cavity. A liquid level sensor and a processor track the amount of fluid within the container. When they detect liquid added to the container, they trigger one or more UV light sources for sterilizing the liquid. A cap sensor in or on the container assembly senses if the cap is on the container and prevents UV light source operation when the cap is off. The processor may communicate with a remote device, e.g., a smart phone or server, via an antenna. Indicators in or on the container assembly notify a user that UV sterilization is recommended, UV sterilization is in progress, etc.
