| 20100012383 | HIGH PRODUCTIVITY CORE DRILLING SYSTEM - High productivity core drilling systems are described. The system includes a drill string, an inner core barrel assembly, an outer core barrel assembly, and a retrieval tool that connects the inner core barrel assembly to a wireline cable and hoist. The drill string comprises multiple variable geometry drill rods. The inner core barrel assembly comprises a non-dragging latching mechanism, such as a fluid-driven latching mechanism that contains a detent mechanism that retains the latches in either an engaged or a retracted position. The inner core barrel assembly also comprised high efficiency fluid porting. Accordingly, the drilling system significantly increases productivity and efficiency in core drilling operations by reducing the time required for the inner core barrel assembly to travel through the drill string. Other embodiments are also described. | 01-21-2010 |

| 20090173542 | VIBRATORY UNIT FOR DRILLING SYSTEMS - A down-the-hole vibratory unit for a drilling system includes a casing comprising a fluid inlet, and a plurality of eccentrically weighted rotor assemblies positioned at least partially within the casing and in fluid communication with the inlet, the eccentrically weighted rotor assemblies that are unbalanced relative to a central axis and are configured to rotate in response to a fluid flow directed thereto to apply centrifugal forces to the casing. | 07-09-2009 |

| 20080288149 | Method And System For Regulating Vehicle Dynamics - A method of regulating the driving dynamics of a vehicle by controlling a torque distribution from a vehicle engine between at least two axles of the vehicle is disclosed. The method comprises controlling the torque distribution with a nominal velocity difference between the different axles as an input value. According to an embodiment, the sign of the velocity difference between both outgoing shafts from the double coupling device is used to determine a control state of the double coupling. | 11-20-2008 |

| 20090128139 | MAGNET POSITION LOCATOR - In one illustrative embodiment, the present subject matter is directed to a device adapted to determine the position of a target magnet, wherein the device includes a pair of orthogonal magnetic field sensors laterally disposed along an axis that is substantially transverse to an axis defined by one that is nominally parallel to the direction of the target magnet. In another illustrative embodiment, the subject matter is adapted for use on an automated guided vehicle (AGV), whereby detection of the target magnet's location facilitates correction of the vehicle's heading and position while traversing an AGV system. The present subject matter is also directed to a method whereby the position of a target magnet may be determined by triangulation, utilizing trigonometric calculations based upon the strength and direction of the magnet field to determine the magnet's position relative to the magnetic field sensors. | 05-21-2009 |

| 20100222916 | METHOD AND APPARATUS FOR PREPARING MAIL PIECES - A method and apparatus is disclosed for preparing mail pieces. By determining the number of postal items of a mail set that is fed or to be fed to a gathering station, the further processing can be based thereon, and if the number of postal items exceeds a predetermined maximum, the mail set is split by transporting the already gathered postal items from the gathering station to the inserting station, where the postal items are inserted in an envelope and an envelope printer can print an association marking on the envelope of the formed mail piece. | 09-02-2010 |
| 20110060450 | AUTOMATED MAIL INSERTING - The present invention relates to a method for verifying the match of envelopes and documents in an automated matched mail system, by for a first envelope and a first document, scanning a face of the envelope and extracting envelope-addressee data indicative of the human-readable addressee information on the envelope; scanning the document so as to extract document data indicative of the content of the document; searching through the document data to locate a match to the envelope-addressee data and designating an area of interest within the document at the location at which the match occurs; for a further envelope and a further document, scanning a face of the envelope and extracting envelope-addressee data indicative of the human-readable addressee information on the envelope; scanning the document so as to extract document-addressee data at a location within the document corresponding to said designated area of interest and comparing the envelope-addressee data and the document-addressee data so as to verify the match of the further envelope and further document. | 03-10-2011 |
