Abstract: A method for encoding/decoding a message with One Time Pad (OTP) process, includes receiving a message to be encoded and an ordered dataset. A PRNG is parameterized with an initial seed that is used in a harvesting operation, which selects data from the dataset to create a current entropy plane of the selected data. In an encoding operation a portion of the received message is selected. The current entropy plane is scanned and data from which data is selected. The location of the selected data from the entropy plane is determined and marked as used and then assembled in an encoded message. This operation is repeated until no unmarked data is present in the current entropy plane. A new entropy plane is generated, and the scanning operation repeated until all portions of the received message have been processed. The process is reversed for a decoding operation.

Abstract: A tire changer with bead seating apparatus including a base, a wheel support including clamps movable between wheel rim gripping and non-wheel engaging positions, a shaft rotatably journalled on the base and mounting the wheel support for rotation on the base, a device for rotating the shaft and thus the wheel support, a plurality of nozzles, one for each of the clamps, mounted on the associated clamp for movement therewith, and an air passage including a conduit in the shaft for directing air under pressure to the nozzles.
