Abstract: A method of managing an inventory of a consumable substance stored in a portable container including sensing at least an indication of an attribute of the substance and generating data from said sensing. The method may further provide generating a notification based on the generating, such as by applying a notification trigger rule, receiving data including the indication of the attribute of the substance, evaluating the notification trigger rule using the data, and selectively generating an access notification based on the evaluating. The method may include sensing or generating in association with a container access event. The method may include associating an identifier with one of a container, a sensor or a substance. A system implementing this and other inventory management methods is also disclosed.

Abstract: Methods for determining an attribute of a substance in a container in response to an access event. The methods include a method for determining an attribute of a substance including activating the sensor in response to an access event and transmitting, in response to the activating, an output of the sensor providing an indication of an attribute of the contents. The methods also include a method having the steps of associating a sensor having an identifier with the container; and receiving the identifier and an output of the sensor providing an indication of the amount of the contents.

Abstract: A modular device for determining attributes of a substance stored in a container having a sensing module, a transmitter module and a power source module. The sensing module is capable of sensing attributes of a substance and providing an output. The transmitter module is configured to transmit an output of the at least one sensing module when operably coupled to the sensing module. The power source module is capable of being operably connected to the sensor module and the transmitter module to power the sensor module and the transmitter module.

Abstract: A method of managing an inventory includes associating an identifier with a container system component such as a container, a sensor or a substance, where the sensor is configured to determine an indication of an attribute of the substance stored in the container. The method further may include associating an identifier with a container system member within a dataset remote to the container; remotely receiving container system data including the identifier and the indication of the attribute; and performing at least one data processing task associated with the container system data.

Abstract: A method and system of managing inventory of consumables stored in containers including associating with a container a sensor configured to determine an indication of the amount of an attribute, such as an indication of an amount of substance stored in the container, and storing the indication of amount at various times as a usage history.
