Abstract: An apparatus and method that monitors the consumption of a beverage containing vessel, while the vessel is contained in a pack, bag, or pocket. The method for monitoring includes a sensor that collects data on the beverage withing the vessel, including initial fluid levels. The data may be broadcast to other devices where the data is analyzed to generate information, and it is displayed. The apparatus may consist of a battery, battery circuit, sensor circuit, temporary storage, sensor, and antenna. The initial fluid level may be determined by the sensor or a third party prior to use by the sensor circuit. Information created may include a warning of when the vessel will be empty relative to the activity of the user.

Abstract: A method for suppressing a non-periodic random event in a proximity system includes: receiving an output signal generated by a proximity sensor in the proximity system and monitoring at least a magnitude of the output signal; determining whether a spike having a magnitude exceeding a prescribed threshold value has occurred in the output signal; when a spike in the output signal is detected, setting an output of the proximity system to a prescribed level for a prescribed duration of time; when the prescribed duration of time has elapsed, determining whether the output signal meets one or more prescribed criteria indicative of a shutdown condition; when it is determined that the output signal meets the prescribed criteria, setting the output of the proximity system to a level exceeding an alarm threshold; and when it is determined that the output signal fails to meet at least one of the prescribed criteria, releasing suppression of the output of the proximity system.
