A shipping container for detecting conditions of the container from a remote location, or sensing the condition of other shipping containers within the vicinity of the shipping container, is disclosed. The shipping container may include an onboard microserver communicating with a plurality of sensors within the container. The microserver may serve as an Internet node enabling sensed conditions within the container to be communicated to remote computing devices by way of the Internet. The shipping container also may include anti-tampering equipment such as a conductive grid such that any tampering with the container will necessarily effect an electrical parameter of the grid with the change in the electrical parameter then being detected and causing an alarm or other corrective measure to be taken.

There are provided a restricted area including an area in which solar cell modules are installed, a preventer for preventing intrusion of an intruder into the restricted area, and a detector capable of detecting the intrusion of the intruder into the restricted area, and a predetermined electric shock preventer is activated by a signal outputted from the detector upon detection of the intruder to prevent the intruder from receiving an electric shock.

The objective of the present invention is to detect, using a universal method, any “movement” inside of the object being monitored, while maintaining the security of a container. The movement inside of the object to be monitored includes 1) a human movement when a human enters into a container to be monitored, 2) a movement to bring a foreign article in, 3) a movement to take cargo out. To achieve the objective, this invention uses the concept of a so-called “inside-seal”. In actual configuration, a plurality of communication units (communication nodes) are installed on the walls of the container. These communication units have a predetermined powered communication capability and form a communication network communicating with each other. A communication status between each node and all of the other nodes provided in the network, and a network graph matrix is generated which defines the nodal relationship between the nodes. Since the matrix is determined not only by the property of the object to be monitored, but also by the spatial condition within the container, it is possible to detect even a small change in the space. According to the first preferred embodiment, each node transmits a low power electric wave which can reach only neighboring nodes, and each node can transmit data to remote nodes only by relaying the data to the neighboring nodes. The relaying counts (HOP counts) of each node to communicate with all of the other nodes are obtained, and based on these relaying counts, a network graph matrix is generated which defines the relaying counts to communicate between all nodes. According to the second preferred embodiment, each node transmits UWB waves to all of the other nodes, which can reach to all of the other nodes, and the distances between all the nodes are measured and a network graph matrix between all the nodes is generated.

A display system for displaying an item of merchandise in a retail environment that allows a potential customer to handle the item while it is secured to the display system. The item is supported on a display shelf and is connected to a retractable cable. The shelf is locked to a base by an alarm unit. Unauthorized removal of the shelf, base, item of merchandise, severing of the retractable cable or alarm unit will activate an alarm. First and second locks lock the alarm unit to the base.

A system for remotely monitoring the status of one or more fire extinguishers includes means for sensing at least one parameter of each of the fire extinguishers; means for selectively transmitting the sensed parameters along with information identifying the fire extinguishers from which the parameters were sensed; and means for receiving the sensed parameters and identifying information for the fire extinguisher or extinguishers at a common location. Other systems and methods for remotely monitoring the status of multiple fire extinguishers are also provided.

An alarm interface for a merchandise security system is coupled to an alarm system of the merchandise security system. The alarm interface includes one or more wireless interface transmitters and receivers. One or more output devices are connected to at least one of the one or more wireless receivers. In one aspect, the alarm system includes a controller for sensing alarm events, one or more hubs connected to the controllers, and a plurality of sensors capable of attachment to a plurality of objects to be secured. A set of sensors within the plurality of sensors is attached to a corresponding hub, and each sensor or hub generates an alarm event when separated from the controller or object to be secured. The wireless interface transmitters wirelessly transmit one or more alarm signals from the alarm system. The wireless interface receivers are adapted to receive at least one of these alarm signals transmitted from one or more of the wireless interface transmitters. One or more of the output devices are activated by at least one of the wireless interface receivers in response to at least one alarm signal-received by the receiver.

A system for protecting an electronic device from mechanical intrusion attempt. An intrusion barrier able to detect mechanical intrusion by means of circuit traces which detect any change in the resistance characteristics of the electric circuit. These circuit traces function as a resistors and they are connected together to form a Wheatstone bridge. According to the present invention the logical lay-out of these connections is selected so that the voltage difference between two adjacent traces is minimized. In this way the current leakage effect is limited to the minimum.

There is provided a passive RFID transponder assembly that includes a condition responsive device adapted to read a condition relating to the component that is associated with the RFID transponder assembly. The condition that is read by the condition responsive device relates to physical contact with a field technician or a mating component, relates to electrical connection between an integrated circuit chip and an antenna, relates to one or more environmental conditions, or the like. The components with which the RFID transponder assemblies are associated include components of telecommunications equipment, such as fiber optic connectors, fiber optic adapters, fiber optic patch panels, copper connectors, and copper adapters to list some non-limiting examples.
