Abstract: A digital air flow detector that includes a pair of thermistors contained in a probe. When installed, an external thermistor is positioned in an air stream, while an insulated thermistor is not. When air is flowing, the air stream will change the temperature of the first thermistor more than the second thermistor. A microcontroller unit measures the temperature difference between the two thermistors and determines whether air is flowing based on the difference. The digital air flow detector outputs an accurate binary indication of whether the air is flowing or not flowing. An air flow detector includes a probe assembly and a printed circuit board assembly coupled to the probe assembly.

Abstract: Methods and systems for tracking an object comprise a horizontal surface upon which objects are to be placed, a weight sensor disposed on one side of the horizontal surface, and a processor in communication with the weight sensor. The processor is adapted to detect a change in weight measured by the weight sensor, to associate the detected weight change with an identified object and with a location on the horizontal surface, and to confirm whether a cause of the weight change at the location on the horizontal surface corresponds to a proper handling of the identified object.

Abstract: A shelving system has at least one shelf, a camera fixed at a distance from the at least one shelf such that a field of view of the camera faces the at least one shelf and closely encompasses the at least one shelf, and a controller in communication with the camera. The controller has a processor adapted to receive images captured by the camera within the camera's field of view and to determine from the images whether a particular object has been placed on, moved, or removed from the at least one shelf.
