Abstract: In some embodiments, a method includes generating a round key for each round from one or more rounds for encrypting input data and partitioning the input data into one or more data blocks for each round. A block key is generated for each data block and each data block is encrypted using the round key, the block key and the data block as inputs to a mathematic operation to produce a cipher text. A number of rounds is variable, at least one of a size of the round key or a number of data blocks are variable for each round, or at least one of a size of each data block, a size of the block key for each data block, the mathematic operation for each data block, or a size of the cipher text for each data block are variable for each data block within each round.

Abstract: A system comprises an input obfuscation module and an input encryption module coupled to the input obfuscation module. The input obfuscation and encryption modules are configured to define a first end of a secure channel for exchanging information with a secure software application module. The system further comprises an output de-obfuscation and decryption module coupled to the input obfuscation and encryption modules and is configured to define a second end of the secure channel, the secure channel having no seams between the first end of the secure channel and the second end of the secure channel. The system further comprises an output de-obfuscation module coupled to the output decryption module.

Abstract: A massaging appliance for massaging the face or other part of the body, comprises a housing enclosing an electrical motor, and a cream applicator having a chamber for containing a supply of cream to be applied during massaging. The applicator has a cylindrical side wall closed at one end by a first end wall to be placed in contact with the respective part of the body to be massaged, and closed at its opposite end by a second end wall coupled to the motor to be driven thereby. The first end wall is formed with a plurality of openings each occupied by a ball rotatably mounted therein for dispensing cream to the contacted part of the body, and the second end wall is formed with a central threaded opening. A piston is disposed within the applicator and includes a threaded stem receivable in the threaded opening of the second end wall enabling the piston to be adjusted, to contract or enlarge the chamber, by rotating the applicator side wall with respect to its second end wall.

Abstract: A device for removing body hair comprises a manually-grippable housing, and a hair-plucker body rotatably mounted to the housing and having an exposed section formed with a plurality of gaps in its outer surface which open and close during the rotation of the hair-plucker body to receive, pluck and eject body hair growing on a surface over which the hair-plucker body is moved. The hair-plucker body includes a pair of drums mounted in spaced parallel relationship, and a belt enclosing the drums and engaging their outer surfaces so as to be rotated thereby. The belt is formed with a plurality of gaps extending circumferentially of the belt. One of the drums is configured so as to cause the portion of the belt engaging it to open its gaps, and the other drum is configured so as to cause the portion of the belt engaging it to close its gaps.

Abstract: A device for removing body hair comprises a manually-grippable housing, and a hair-plucker body including a stack of circular discs of uniform diameter fixed to a resilient cylindrical core of smaller diameter passing through their centers. The core is supported in an arcuate position and is rotated about its longitudinal axis such that the outer edges of the discs open at the convex side of the core during its rotation, to receive the hairs between the outer edges of the discs, and close at the concave side of the arcuate core during its rotation, to clamp the hairs between the outer edges of the discs and to pluck them from the body.

Abstract: A tool for loosening fasteners, comprises an applicator bar formed with a socket for receiving the fastener to be loosened, a handle fixed to a housing rotatable about the applicator bar for loosening the fastener received in the socket, a hammer within the housing and connected thereto by a spring, and an anvil carried by the applicator bar. The tool further includes a rod coupling the anvil to the hammer in the initial position of the hammer and effective to prevent relative movement therebetween, and thereby to load the spring during the rotation of the operating handle in one direction, and a releasing device effective, after the operating handle has been rotated a predetermined distance, to release the coupling rod, whereby the loaded spring causes the hammer to impact against the anvil to thereby loosen the fastener received in the socket of the applicator bar.

Abstract: Apparatus for rocking a baby holding device having four legs supporting same on the floor, comprises a roller for supporting each leg so as to be rollable over the floor, and a rocker device including a base adapted to be non-rotatably supported on the floor, a holder rollably supported on the base and adapted to receive its respective leg of the baby holding device, and an electrical motor for rocking the holder with respect to said base. The rocker device further includes a tape recorder for playing music or the like during the operation of the rocking device.

Abstract: A faucet includes a shut-off valve between its inlet connection and its spout, and a valve operator extending below the spout so as to be engageable by a user's hand when located below the spout to receive the water discharged therefrom. The valve operator comprises a stem passing through the spout and a latching device which latches the valve in the "on" position by one operation of the valve operator, and in the "off" position by the next operation.

Abstract: A depilatory device for removing body hair, comprises a manually-grippable housing, and a hair-plucker body rotatably mounted to the housing and having an exposed section formed with a plurality of gaps in its outer surface which open and close during the rotation of the hair-plucker body to receive, pluck, and eject body hair growing on a surface over which the hair-plucker body is moved. The hair-plucker body is a flexible cylindrical member of plastic on elastomeric material having a smooth outer surface formed with a plurality of slits penetrating only partially through the cylindrical member and extending circumferentially thereof.
