The module may be embedded within a wall of the container or affixed to an outside surface of the container. The module may be an active device initiating an interrogation or a passive device merely responding to a received interrogation signal. | 12-10-2009 |
20110024192 | METHOD AND APPARATUS FOR COLLECTING DRILL BIT PERFORMANCE DATA - Drill bits and methods for sampling sensor data associated with the state of a drill bit are disclosed. A drill bit for drilling a subterranean formation comprises a bit body and a shank. The shank further includes a central bore formed through an inside diameter of the shank and configured for receiving a data analysis module. The data analysis module comprises a plurality of sensors, a memory, and a processor. The processor is configured for executing computer instructions to collect the sensor data by sampling the plurality of sensors, analyze the sensor data to develop a severity index, compare the sensor data to at least one adaptive threshold, and modify a data sampling mode responsive to the comparison. A method comprises collecting sensor data by sampling a plurality of physical parameters associated with a drill bit state while in various sampling modes and transitioning between those sampling modes. | 02-03-2011 |
20130087386 | EXPANDABLE APPARATUS AND RELATED METHODS - An expandable reamer apparatus and methods for reaming a borehole, wherein a laterally movable blade carried by a tubular body may be selectively positioned at an inward position and an expanded position. The laterally movable blade, held inwardly by blade-biasing elements, may be forced outwardly by drilling fluid selectively allowed to communicate therewith by way of an actuation sleeve disposed within the tubular body. Alternatively, a separation element may transmit force or pressure from the drilling fluid to the movable blade. Further, a chamber in communication with the movable blade may be pressurized by way of a downhole turbine or pump. A ridged seal wiper, compensator, movable bearing pad, fixed bearing pad preceding the movable blade, or adjustable spacer element to alter expanded blade position may be included within the expandable reamer. In addition, a drilling fluid pressure response indicating an operational characteristic of the expandable reamer may be generated. | 04-11-2013 |

20080301791 | Single sign-on system, method, and access device - A system, method, and access device enabling a user to securely access a plurality of password-protected servers with a single entry of the user's User ID and associated password. When the access device receives the User ID and password from the user, it sends only the User ID to each of the password-protected servers. The servers each return a unique index value to the access device. The access device uses each index value to retrieve different password modification information from a database or lookup table. The access device then creates a plurality of modified passwords based at least in part on the password modification information. The access device then transmits each of the modified passwords to the corresponding password-protected server. | 12-04-2008 |
20090089450 | System and method providing secure access to a computer system - A system and method for providing secure access to a computer system. An access device divides the password into multiple segments and places them in data packets. In one embodiment, an authentication server has multiple addresses, and each packet is sent to a different address. The server then reassembles the password. In another embodiment, when the server receives a password, the server sends an index value back to the access device, which then accesses the server on another address indicated by the index value. Alternatively, the password is sent to multiple addresses for the server, and the server determines whether any of the received packets have been altered. The multiple password packets may be forced to follow different paths to the server, thereby denying hackers the ability to intercept all of the password characters or determine the inter-packet timing factor. The system is effective against passive and active hackers, Trojans, and phishing techniques. | 04-02-2009 |
