International Classification:

G08B 13/08

US Classification:

340549, 3405451, 3405457, 340550, 340546

Abstract:

A container security system has a container interior monitor portion with a container interior light sensing portion responsive to visible light. A different embodiment involves a monitoring device with a support, a door engaging member movable to and from an operational position, and a detection portion that generates an electrical signal in response to movement of the member away from the operational position. The support may be configured to be supported on an edge portion of a movable door. Alternatively, the monitoring device may include a wireless communication portion, and circuitry responsive to the signal and operatively coupled to the wireless communication portion.

Abstract:

A device has a support that can resiliently and removably grip an edge portion of a member with first and second portions thereof disposed on opposite sides of the member. A further portion on the first portion can operatively couple sensing structure to an electrical conductor portion on the third portion. A different embodiment has a support that can resiliently and removably grip an edge portion of a member with first and second portions thereof disposed on opposite sides of the member. A further portion on the support has circuitry coupled to a wireless communication portion on the first portion. Another embodiment has a support with structure supported thereon, the support resiliently and removably gripping the edge portion of a movable door with first and second portions of the support disposed on opposite sides of the edge portion.

International Classification:

G08B 13/14

US Classification:

3405721, 340 101, 340 105

Abstract:

An identification device establishes a relative hierarchy of associated containers as logistical units, providing multi-layer visibility of nested and adjacent containers. The relative hierarchy comprises lower-layer containers and upper-layer containers relative to the identification device. An integrated reader device reads heterogeneous tag types. This allows disparate tag types simultaneously using a single device.

International Classification:

G08B 13/14

US Classification:

3405721, 3405724, 3405681

Abstract:

An apparatus includes a carrier, and a system that is responsive to wireless signals transmitted by tags on items carried by the carrier for maintaining a local inventory of items carried by the carrier. A different apparatus involves a carrier having a container with an interior, a sensor for detecting a condition externally of the container that can be related to an environment within the container, and a system that handles information from the sensor in a manner facilitating an evaluation of the likelihood that a problem exists within the container. Another apparatus involves a carrier for a plurality of items, and a system that is responsive to wireless signals received from a remote location for determining a current location of the carrier and for evaluating whether the carrier is proceeding along an intended route.

International Classification:

G08B001/08

US Classification:

340/539260

Abstract:

A container for locally determining a container state using a state device. The state device detects unexpected events by comparing expected event information with actual event information related to a container condition. The container condition includes, for example, environmental conditions, logistical or location conditions, and physical or security conditions. Thus, the container is able to intelligently monitor its state and raise an alert without intervention from a central system. The container can also be programmed and reprogrammed with updated logic, states, and/or expected event information. A sensor in the state device gathers input information for comparison to expected event information. A communication port in the state device receives event information. For example, a GPS (Global Positioning System) receiver can determine a current location for comparison to an expected location at the current time. In another example, an RFID (Radio Frequency Identification) receiver and transmitter automatically uploads state information to a central system.

International Classification:

G08B 1/08

US Classification:

340539130

Abstract:

A tag has a transmitter for transmitting first wireless signals, and a receiver for receiving second wireless signals from which the tag can determine its current physical location. A different embodiment includes a tag having a transmitter for transmitting wireless signals, and a reader having a receiver for receiving the wireless signals, the receiver in the reader being an ultra-sensitive receiver.
