Abstract: Anthrax is an often fatal infections disease arising from Bacillus anthracis bac-teria spores. A safe and secure mail delivery system helps to bring about a future where packages are delivered on time, crime (terrorism, etc.) is low, and morale is high. In one embodiment, biometric verification of recipients ensures packages are not delivered to the wrong recipient. Preferably the sender can visually verify the recipient's identify, as well as visually track the manner in which the package is han-dled. Preferably the package cannot be handled or even touched by the mail carrier, but can be handled by security forces, officers, or by the recipient, by virtue of a mail carrying housing (such as a briefcase) that can be opened by anyone except the person carrying it. Preferably the housing comprises a fingerprint scanner, or a vaccination chip reader, that can be programmed so that the carrier cannot open it. In some embodiments, a mailroom facility is provided, where persons arriving at the facility are requirement to undress completely before being allowed to pass into a shower room for decontamination with an appropriate decon solution. The invention includes means for preventing persons from leaving the mailroom without passing through the shower room. Preferably persons can only pass through the facility in one direction: persons first enter a clothing bagging area where they must remove all clothing, jewellery, personal effects, or other devices that could harbour contamina-tion or chemical agents. Preferably there are dual pathways, one for men, and another for women, each comprising a bagging room, a shower area, and a vaccination area, with a seventh triage observation area, or remote video link and remotely operable passage locks, plumbing valve controls, and vaccination machines for triage personnel to supervise, observe, and administer the vaccination process.

Inventor: MAIN ALEC
IPC: G06F21/14
Filed: 2001-06-28
Abstract: Mass data (the contents of arrays, large data structures, linked data structures and similar data structures stored in memory) are common targets for attack. The invention presents a method and system of protecting mass data by mapping virtual addresses onto randomly or pseudo-randomly selected actual addresses. This mapping distributes data values throughout the memory so an attacker cannot locate the data he is seeking, or identify patterns which might allow him to obtain information about his target (such as how the software operates, encryption keys, biometric data or passwords stored therein, or algorithms it uses). Additional layers of protection are described, as well as efficient techniques for generating the necessary transforms to perform the invention.

Title: Standard attachment fittings for wire rope and chain enhanced to also perform load weighing functions
Inventor: SIMONS GERALD S
IPC: G01G19/18
Filed: 2001-12-14
Abstract: Standard attachment fittings for wire rope and chain (WR&C) that are enhanced to also perform load weighing functions in lifting/support or pulling assembly applications. The existing unmodified shape of each typical WR&C fitting provides focused linear strain under tensile or compression loading at determinable points on the fitting body.  Affixing a strain gauge element to any of these points will enable accurate load weight measurement eliminating the need for a separate weigh scale and a "thin section" typically required in load sensors to focus load strain and achieve accurate load weight readings.  The invention addresses increased WR&C fitting assembly simplicity, preserved structural integrity, improved assembly compactness, reduced cost, enhanced safety and maintenance of the original application functions of the standard attachment fittings whilst enhancing the said fittings with weighing function capability.
