A system for indicating the integrity of a normally sealed package utilizes a sensor containing a pH sensitive dye which displays a first color at normal atmospheric pH and a second color above normal atmospheric pH. An artificial atmosphere containing a basic gaseous material, which maintains the dye in its second color so long as the integrity of the sealed package is maintained, is then introduced in the package.

A platform featuring memory which contains a plurality of software components and a manifest which includes a digest of each of the plurality of the software components and a processor which is coupled to the memory. The processor executes a hash function to produce the manifest and to verify integrity of the plurality of software components by re-computing digests of the plurality of software components and comparing the computed digests with the digests of the manifest.

There is provided improved physiologically acceptable articles made from various fluorocarbon polymers and a process for maintaining the normal integrity of the blood of warm-blooded animals with said articles. The physiologically acceptable articles include specific medial devices such as catheters, etc., useful in contact with blood or tissue in warm-blooded animals.

A server blade may comprise a processor and a network interface. The network interface can be configured be connected to a network remote the server blade. The server blade may be configured detect a property of an entity connected to the network. The server blade may be further configured as a field replaceable unit. Optionally, the server blade may further comprise an enclosure which encloses the processor.

The test device is an electrolytic apparatus for the simultaneous non-destructive testing of the integrity of pluralities of circuit boards for continuity and anti-continuity or short circuits, including such circuit boards as employ multi-layer or multi-level interconnection wiring, whether it be printed wiring or screen printed or thermally deposited circuits. Transient electro-deposition of one ion from an alkali halide water solution temporarily modifies the optical reflectivity of exposed c...

A device to monitor the mounting and bearing integrity of a wheel mounted on an axle where a multiplicity of studs are used each having retainers therefore. A follower of generally dielectric material and having an electrical conductor is biased against the side of the wheel. An electrical contact maintains contact with the follower periphery and is relatively movable between the dielectric periphery and the conductor located in the periphery. The first electrical contact is fixed to the vehicle...

A tanker integrity system for minimizing any cargo loss and preventing any ship loss due to collision, etc. and providing for closing and pressurizing the tanker holds and for selectively transferring cargo between holds and offloading cargo from the ship notwithstanding loss of the ship power plant and/or damage to the ship resulting in the ship breaking in two.

An optical frequency domain distributed strain sensor for determining the strain distribution along an optical fiber includes an optical source that provides a polarization controlled optical interrogation signal having a frequency that varies in a recurring linear manner. The interrogation signal is injected into a sensor fiber embedded within a composite structure that places the fiber under strain. A portion of the interrogation signal is backscattered from the sensing fiber as a consequence ...

A method and apparatus for determining the conductive integrity of a plurality of lines which transmit electromagnetic radiation.

A vacuum operated testing device measures the bond integrity of wires connected to integrated circuit modules by applying a known and infinitely variable tensile force to the wire under test.
