Abstract: A method and apparatus for blind alignment of electronic circuit boards. A receptacle with two vertical flanges and one horizontal flange is positioned relative to an electrical connection. A circuit board having a notch on a leading edge is proximally positioned to the receptacle. As the notched edge is moved toward the receptacle, the flanges guide the board into a registered position relative to the electrical connection. The method and apparatus may be used in any number of alignment situations including those as disparate as robotic assembly operations and assembly by untrained consumers and end-users.

Abstract: A method and apparatus are disclosed for improving public key encryption and decryption schemes that employ a composite number formed from three or more distinct primes. The encryption or decryption tasks may be broken down into sub-tasks to obtain encrypted or decrypted sub-parts that are then combined using a form of the Chinese Remainder Theorem to obtain the encrypted or decrypted value. A parallel encryption/decryption architecture is disclosed to take advantage of the inventive method.
