A method of determining the watertight integrity of the floatation hull of ir cushion vehicles, ground effect machines, and hovercraft by measuring the differential air pressure between the air pressure in the hull or individual airtight floatation compartments during operation of the vehicle and the air pressure in the static condition. Under normal operating conditions, the compartment air pressure-atmospheric pressure differential is the same as when the vehicle is static. If a leak occurs in...

A beam of spectral energy is directed onto a weld spot and the integrity of the weld is measured by the strength of the reflected beam or of the transmitted beam, which may also involve a function of the refractive characteristic effect of the weld spot on the incident beam.

An apparatus and method for self-healing of software may rely on a distribution object in a directory services of a network to provide data for controlling distribution of software and installation of files associated therewith. A software object may represent a software product, system, data structure, application, or the like, from a single byte, to a complex program. A directory services system is responsible for maintaining a data store of inter-related logical entities (directory services o...

A method and system for monitoring integrity of a filter (25) of a smoke or fire detector system. The system has a detector chamber (14) into which light is passed from a light source incorporated into a light source control circuit (10). Scattered light is detected by a light scatter detector (12). Controller circuit (16) receives signal from the detector (12) and makes a cumulative count over time of the number of dust particles detected.

Vias are formed by depositing a hard dielectric mask layer on the upper surface of a lower metal feature and forming sidewall spacers on the side surfaces of the metal feature and mask layer. Embodiments include depositing a dielectric interlayer and forming a misaligned through-hole therein by etching. The dielectric material of the sidewall spacer and dielectric material of the dielectric interlayer are different. The etchant employed to form the through-hole exhibits a high selectivity with r...

A method for assessing the integrity of a structure, comprising the steps of: i) collecting data relating to the initial dimensions of the structure, ii) creating a computer model of the structure, iii) collecting data relating to the estimated load on the structure, iv) analysing the structure, using the computer model of the structure and the load data, in order to define areas which are subject to relatively high stress, v) measuring, after a time interval, the dimensions of the structure in ...

A method for testing the integrity of a memory with defective sections under a plurality of operating environments includes testing the memory with defective sections under a plurality of operating environments, recording results of each operating environment test, and comparing the results of the tests. If the results of are the same, the memory with defective sections is declared to have integrity. If not, the memory with defective sections is declared to not have integrity.

Disclosed are voting systems based on paper ballots that provide integrity of the election outcome through the novel use of encrypted votes and other techniques. In some example embodiments, holes through layers allow voters to see and mark symbols on lower layers, carbonless coatings allow voters to obtain substantially identical marks on facing surfaces, self-adhesive stickers are removed from one position and placed by voters hiding vote-revealing indicia on a second position, and scratch-off...

Techniques are described herein that may utilize capabilities of a data mover in order to determine an integrity validation value or perform an integrity checking operation. The integrity validation value determination and integrity checking operations may be controlled by descriptors or instructions. In some implementations, integrity validation value determination and the integrity checking operations may include determination of a cyclical redundancy checking (CRC) value.

The present invention is directed to novel systems and methods for authenticating the pedigree and/or confirming the integrity of a transported package. Among other things, a method is disclosed that involves receiving information from an electronic device associated with the package at an authentication appliance at a destination location, transmitting at least a first portion of the information from the authentication appliance to a server, receiving from the server a network address of an aut...
