Abstract: A system for wireless communications includes multiple portable digital devices which automatically and selectively communicate with each other. Each portable digital device has a proximity transceiver and an electronic memory which stores the user's and listing of matched identification codes which represents all compatible PDD users. During operation, the portable digital devices communicate with each other by transmitting identification codes and receiving identification codes. The PDD compares the received identification code to the listing of matched identification codes to determine if there is a match. If the received identification code is on the listing of matched identification codes, a match is detected the match indicators of the PDDs are actuated to inform the users that a match has been detected.

Abstract: A system for wireless communications includes multiple portable digital devices which automatically and selectively communicate with each other. Each portable digital device has a proximity transceiver and an electronic memory which stores the user's personal information and search information. During operation, the portable digital devices communicate with each other by transmitting signals through the proximity transceivers. A compatibility analysis is performed to determine if their users are compatible by comparing the personal information of each user to the search data of the other user. If the first user's personal information matches the second user's search data and the second user's personal information matches the first user's search data, both users are notified that they are compatible and information is electronically exchanged.

Abstract: A method and apparatus for direct access to a processor via an external multi-purpose interface. The present invention provides an interface that detects the presence of a diagnostic device, such as a diagnostic PCMCIA card, or other device, and provides a direct connection to the processor. The direct connection to the processor is not available to non-diagnostic devices.

Abstract: A fan stator includes a split outer casing having a pair of outer rails, and a pair of key slots disposed at a splitline thereof. A plurality of standard stator vanes have outer platforms and hooks which engage the casing rails for supporting the vanes, with the vanes also having inner hooks extending from inner platforms thereof. A pair of locking stator vanes are disposed at the casing splitline and include an outer platform having outer hooks which engage the casing rails, an anti-rotation key disposed in the casing key slot, and an inner platform having first and second locking hooks extending therefrom. The first locking hook is equal in size with the first inner hooks and includes a first dam blocking the first locking hook at one end thereof, and the second locking hook is axially shorter than the second inner hooks and includes a second dam blocking the second locking hook at the same end thereof.

Abstract: An improved gas turbine engine blade having increased resistance to foreign object damage is disclosed. The blade includes a swept-back leading edge portion in the tip region of the blade for improving resistance to tip curl due to foreign object impact.A method of forming such a gas turbine engine blade from a blade having leading edge tip curl caused by foreign object damage is also disclosed.
