Abstract: An item monitoring system for tracking and reporting absence of items such as tools from assigned storage locations. Non-contact sensors are used to capture a mosaic of sensed areas that are processed and compared to previous sensed areas identifying change in the presence or absence of items. When a change is detected the item inventory for the storage location is changed to reflect latest status of present or absent. Scaled to a plurality of storage drawers the item monitoring system provides automatic item inventory status for large storage cabinets which may be linked to a central processing system or queried by hand held terminal.

Abstract: An item monitoring system is provided which is operative at points of storage automatically to sense the presence, number of item(s) stored and relative location of items and to generate near real-time item and location data from storage locations so that time-related changes can be compared to detect item additions and subtractions, and to recognize and report events such as shrink/theft, low inventory conditions and misplaced items. Embodiments incorporate a surface sensing system comprised of one or more contiguous item sensor strips that measure the relative pressure of items in contact with a surface or a hanger support using pressure sensitive analog type conductive material. Item information can be collected from multiple hangers and/or storage surfaces and relayed to databases and application systems for varied uses. The system and method disclosed are cost effective and widely applicable to many categories of inventory application providing real-time updates without item packaging changes.

Abstract: An asset in a group is automatically tracked wherein each asset is tagged, and at least one transport means are associated with at least one Proximate GPS (PGPS) location devices each equipped with a sensor which is receptive to the presence of a known asset. The sensor is able to detect the type of tag(s) associated with assets and associated with the transport means. The transport means transporting a PGPS device during the course of it activities passes by, associates with and/or may relocate a known tagged asset, the PGPS automatically detects the asset tag and stores the first sensed GPS location, asset tag ID, first time in a newly created PGPS record.

Abstract: The asset monitoring system and associated method includes an asset monitor for providing a remotely located central station with information relating to a container, such as a trailer, both during tethered periods in which the energy storage reservoir of the asset monitor is electrically connected to an external power source, such as the electrical system of a tractor or truck, and during untethered periods in which the energy storage reservoir of the asset monitor is electrically untethered or disconnected from the external power source. As a result, the energy storage reservoir is recharged by energy received from the external power source during tethered periods and supplies energy to the asset monitor during both tethered and untethered periods. The asset monitor also includes a controller for controlling its operations. The controller includes tether status determining means for separately identifying tethered periods and untethered periods.
