Abstract: A system (100) and method (400, 500) for data encryption and decryption are disclosed. The encryption system is operable at encryption rates in excess of 10 Mbps and is expandable to over 200Mbps. For encryption, plain characters are received, and a key block (120) includes key characters corresponding to the plain characters is accessed. A current key character corresponding to a current plain character is located. A next key character corresponding to a next plain character is located. An offset between the current key character and the next key character is determined to encryp t the plain characters. Aliases are used to facilitate the encryption and decryption. Vector distances of offsets are utilized for the encryption and decryption, using many variables and many dimensions, such as using coordinates. <IMG>

Title: Automatic transfer regulator for hose-line respirator
Inventor: FETTERS THOMAS ALLEN
IPC: A61M16/10
Filed: 2003-09-30
Granted: 2010-09-14
Abstract: An automatic transfer regulator for automatically switching between a primary (hose line) breathing air source and a secondary source (escape cylinder). A pressure sensing system detects the line pressure of the primary source using a spring loaded poppet connected to one side of a transfer poppet valve, with the other side connected to the output of a reducer. The pressure sensing system is fed by the primary source through an orifice. When the sensor detects loss of hose line pressure, the system pressure is released to ambient. This bleeds the pressure from the system side of the transfer poppet valve, allowing the reducer output to force the poppet back, thus actuating the secondary source. A check valve prevents reducer output from escaping through the primary source inlet.

Title: Allocation of bit streams for communication over multi-carrier frequency-division multiplexing (fdm)
Inventor: MOBLEY JOSEPH GRAHAM
IPC: H04N21/434
Filed: 2002-09-18
Granted: 2014-05-27
Abstract: An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of ethernet frames and/or other data across a cable transmission network (105) or other form of FDM transport.  The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Also, the modulation indices of various upstream frequency channels may be different, but a plurality of upstream channels may be used to carry a single data flow generally in parallel. The upstream data flow is fragmented into blocks and formed into superframes to allow transmission over at least one upstream frequency channels. When a plurality of upstream frequency channels are utilized, the superframes facilitate the possibility of having different modulation indices on the plurality of frequency channels.

Abstract: A power feed apparatus for applying a thrust force to an output shaft (52) of a motor driven tool (34) to drive the output shaft linearly towards and away from a workpiece without applying off-axis forces to the output shaft that would cause it to move out of perfect perpendicular alignment to the outer surface of the workpiece. The apparatus includes a first tubular member (18) which is fixedly secured to a jig or other like mounting structure associated with the workpiece. A second tubular member (20) is disposed for sliding linear movement along the first tubular member. Spaced apart annular fluid chambers (50, 72) are formed within the apparatus along with associated fluid ports (22, 28) for allowing a pressurized fluid to be used to both extend and retract the output shaft of the tool. The tool itself is supported on the second tubular member and thus moves linearly along with the second tubular member.

Title: Systeme de protection cathodique a courant impose et effet galvanique
Inventor: WHITMORE DAVID
IPC: C23F13/06
Filed: 2004-11-24
Granted: 2014-03-18
Abstract: La protection cathodique de l'acier dans un bâtiment ou une autre structure en béton ou similaire est réalisée en plaçant une anode dans un emplacement convenable adjacent à l'acier et en appliquant à l'anode un courant imposé à partir d'une source d'alimentation. L'anode est formée d'un matériau qui est plus électronégatif que l'acier de sorte que, advenant que l'alimentation entre les deux baisse sous le potentiel galvanique, le courant circule grâce à l'action galvanique pour remplacer le courant imposé. Une diode dans le circuit empêche le flux du courant dans la source d'alimentation, mais permet la circulation du courant galvanique lorsque l'alimentation ne se rend pas dans le circuit ouvert. Une autre diode peut être fournie dans l'éventualité où l'alimentation ne se rend pas dans le circuit fermé pour empêcher l'inversion de la circulation du courant.

Abstract: A method for ablating tissue in an organ inside a body of a subject includes bringing a probe inside the body into a position in contact with the tissue to be ablated, and measuring one or more local parameters at the position using the probe prior to ablating the tissue. A map of the organ is displayed, showing, based on the one or more local parameters, a predicted extent of ablation of the tissue to be achieved for a given dosage of energy applied at the position using the probe.  The given dosage of energy is applied to ablate the tissue using the probe, and an actual extent of the ablation at the position is measured using the probe subsequent to ablating the tissue. The measured actual extent of the ablation is displayed on the map for comparison with the predicted extent.
