  • Patent number: 6727881
    Abstract: Disclosed herein are novel electrophoretic displays and materials useful in fabricating such displays. In particular, novel encapsulated displays are disclosed. Particles encapsulated therein are dispersed within a suspending, or electrophoretic, fluid. This fluid may be a mixture of two or more fluids or may be a single fluid. The displays may further comprise particles dispersed in a suspending fluid, wherein the particles contain a liquid. In either case, the suspending fluid may have a density or refractive index substantially matched to that of the particles dispersed therein. Finally, also disclosed herein are electro-osmotic displays. These displays comprise at least one capsule containing either a cellulosic or gel-like internal phase and a liquid phase, or containing two or more immiscible fluids. Application of electric fields to any of the electrophoretic displays described herein affects an optical property of the display.

  • Patent number: 6728378
    Abstract: The invention provides computer-enabled methods and systems for the secure transmission and platform-independent receipt and decryption of encrypted messages. According to the invention messages are encrypted by a symmetric encryption algorithm using a secret key that is, or is based on, a password known to the intended recipient. The recipient is also sent a computer program which upon input of the correct password, uses the password to generate the secret key, or alternatively, uses the password as the secret key. The program then uses the secret key to decrypt the encrypted message. The invention further provides for ensuring the integrity and authenticity of sent and received messages. The communications medium over which messages are sent according to the invention may be a communications network such as the Internet and the messages may be electronic mail messages and MIME messages. The invention also provides for the secure delivery of statement and transaction information pertaining to an account.

  • Patent number: 6725792
    Abstract: A placket sewing machine attaches a placket patch to a fabric part of a garment in overlying relation to form a multiple layer placket assembly. The placket sewing machine includes a base defining a working surface of the sewing machine. A reciprocating needle chuck has first and second needle openings formed in a staggered forward and rearward arrangement. First and second sewing needles are positioned within respective needle openings of the chuck. The sewing needles are adapted for carrying respective ends of thread into and through the overlaid placket patch and fabric part to form first and second parallel lines of stitches in the placket assembly. The first line of stitches extends a greater distance along the length of the overlaid placket patch and fabric part than the second line of stitches. A sewing motor is operatively connected to the needle chuck for actuating the chuck during operation of the sewing machine.
