Appl. No.:

11/091735

Inventors:

Bruce Robertson - Oracle AZ, US
Thomas Wood - Salt Lake City UT, US

International Classification:

H04L012/66

Abstract:

The present invention provides an audio FSK encoded digital data packet embedded in the audio message portion of an EAS protocol transmission, and to methods for encoding and for recognizing and decoding the data packet. A digital audio FSK encoded digital data packet embedded in the audio message portion of an EAS protocol transmission comprises a packet header, control codes, and content data. The data packet header identifies the beginning of the data packet. The control codes provide structural information about the content data segment of the data packet. The content data comprising at least primary text and/or other primary data as described by the control codes, and optionally, containing auxiliary device control data and content encryption data as described by optional control codes, and the end of content data identifying the end of the embedded data packet, all from which an EAS audio FSK decoder may reconstruct the original embedded digital data.

Thomas H. Wood - Roy UT

International Classification:

B23P 1904

US Classification:

29261

Abstract:

An apparatus for removing carrier bearings, axle bearings, or other types of bearings from a support shaft is disclosed. The apparatus includes a pair of housing sections pivotedly mounted as a controllably positioned platform. The platform defines an aperture therein, through which passes a drive shaft. Each housing section defines a lip on its free end adapted to engage the race of a bearing to be removed. Upon the imposition of a force on a bearing's support shaft by the drive shaft, the housing section lips apply a force against the bearing, eventually disengaging it from its mounting on the axle.

Abstract:

An apparatus for removing the spherical ball from a support shaft in a joint assembly is disclosed. The apparatus includes a housing defining a pair of orthogonally directioned, intersecting channels therein. The channels form a recess well configured to receive a ball to be removed. A drive shaft inserted in a third channel defined in the housing provides a means of applying force to the ball's support shaft, thereby causing the housing to abut against the ball and disengage it from its support shaft mounting.
