Abstract: A simple trip-wire or magnetic circuit associated with a shipping container provides continuity, which is detected electrically. Simply, if continuity is disabled by a forced entry of the container, electrical detection means, such as a radio-frequency-identification (RFID) tag, will alert the owner or monitoring station. The trip-wire concept would require the replacing of a broken trip wire (resulting from forced entry), while the magnetic circuit concept can be reused repetitively. In a second embodiment a magnetic circuit and the detection device (RFID tag) are embedded into the shipping article during manufacturing. The preferred detection device, an RFID tag, could also be a battery backed transceiver type on which a replaceable or rechargeable battery could be mounted on the inside of the shipping container during manufacturing. The RFID tag would communicate with an interrogator unit, which could be connected to a host computer.

Abstract: A button-type battery has an anode, a cathode, and an electrolyte encased with two terminal housing members. The terminal housing members have respective peripheries that are crimped together to form a fluid-tight seal. An insulating gasket is provided between the peripheries to electrically insulate the two terminal housing members. A porous separator physically separates the anode and cathode and extends between the terminal housing member peripheries at least partially into the fluid-tight seal. According to one aspect, the separator overlaps the gasket in the seal. According to another aspect, the separator and gasket are formed of a single, integral piece of material. The thickness of the battery is less than one millimeter.

Abstract: The present invention introduces a method of reducing conductive and convective heat loss from the battery unit in battery-powered devices, such as RFID tag devices. Battery heat loss prevention is accomplished by suspending the battery in a vacuum or within a low thermally conductivity gas, such as air, nitrogen, helium or argon. Further improvement is accomplished by using a minimum number of suspension points made of solid material which possesses a low thermally conductivity. The battery can be suspended by various means, the first of which totally encapsulates the battery using the minimum number of solid material suspension points mentioned above, and the second of which only a portion of the battery (such as the lower portion) is suspended in a low thermally conductive material and the upper portion is encapsulated by the low thermally conductive material fabricated in an arching structure that does not contact the upper portion of the battery.
