Abstract: A security bin and a security bin controller are described that measure fullness or height of secure contents in a security bin; listen to radio beacons over a short-range radio to determine a bin distance from a first radio, such as by measuring received radio power; determine one of three bin security states: home, caution or warning; and then broadcast a status message, warning message or alarm message over long-range radio, dependent on both the fullness of the bin and the security state. Embodiments include shredder bins, adapted to receive secure or confidential documents. Status messages may be used to initiate a search for a lost bin or to schedule bin service. Embodiments include measuring rate-of-fill. Alarm messages may be responsive to both bin location and fill volume. Embodiments and use of a controller include waste bins, including industrial or medical waste.

Abstract: A secure document bin is described that includes a bin having a lid that securely affixes to the bin to prevent unauthorized access to the contents of the bin, and an electronics module associated with the bin. The electronics module is formed in part by a location detection circuit and status sensors. The status sensors include a sensor to detect movement of the bin, a sensor to detect tampering with the bin, and a sensor to detect a relative fill level of the bin. The location and status of the secure document destruction bin is monitored by a monitoring center using wireless transmissions from the secure document destruction bin.

Abstract: The present invention enables efficient communication of location identification of remote movable objects or vehicles over capacity-constrained wireless communications systems by transmitting only the truncated latitude and longitude coordinate data relative to a dynamically alterable and previously unknown coordinate reference anchor.

Abstract: A system coupled to one or more vending machines, such as soft drink vending machines, via a wireless data link can acquire operational vending data, for example sales data, hardware status, and product temperature. The system can compile data from multiple vending machines dispersed across a geographic area such as a city or state. The system can include software that refines the vending operations of one or more such vending machines based on analysis of acquired data, taking into consideration other information such as market, business, seasonal, or environmental factors. Refining vending operations can include adjusting product offerings, relocating vending machines, replicating favorable conditions, and addressing unexpected sales variations.
