A system and method for detecting contaminants in or on objects, having a movably mounted container for holding objects and having a plurality of perforations and an entrance opening through which objects may be placed into the container. A housing encloses the container and forms a barrier to ambient air. There is a sealable opening for inserting and removing objects from the container. A drive assembly moves the container within the housing to move objects therein for emitting particles which are in or on such object. There is an air stream for moving air through the housing and container to entrain any emitted particles into the air stream and a sensor for sensing contaminants in the air stream and providing a signal when a contaminant is sensed. The container can be a rotatable cage or a vibrating box. In the method, there is a chamber provided which may be sealed with respect to ambient air to create an enclosed atmosphere. A plurality of objects are loaded into or onto a perforated container disposed within the enclosed atmosphere and an air stream is created within the enclosed atmosphere. The objects are agitated to cause them to emit particles therefrom into the air streamwhichis tested to determine whether it contains any contaminants. If so, a signal is provided.

A bi-directional package divert mechanism used for sorting mail and other packages and items into appropriate bins for future delivery. The mechanism includes a downward extending moving mechanism which is capable of moving items into one of two directions, both perpendicular to an original direction of travel. Sensors are provided which detect a position of the moving mechanism, items for moving and monitoring of other systems.

A system and method for substantially eliminating the release of pathogen agents circulating in the air within a collection box. The mail deposit openings () of a collection box mail chute () are adapted with gaskets () to form an airtight seal when the mail chute () is opened and closed, thereby isolating the collection box interior (). An alternative embodiment can further include a charging device () and a chargeable material () to attract and detain airborne and free pathogen particles that enter the mail chute passage () either by newly deposited mail pieces () or airborne pathogen particles that migrated from within the collection box collection area ().

A motion control system comprises a motion unit having a motor connected to an encoder and an amplifier. The motion control system further comprises a scalable motion controller connected to the motion unit wherein the scalable motion controller receives signals from the encoder and outputs signals to the amplifier. The scalable motion controller comprises a plurality of dip sockets arranged for inserting and removing one or more motion control processors and a connector interface comprising a plurality of male and female connectors arranged for stacking a plurality of motion controllers.
