International Classification:

E21B 44/06

US Classification:

175 48, 175 40

Abstract:

An obstacle avoidance system for obstacle detection in an opaque material. The system includes at least one electromagnetic signal source adapted to produce an electromagnetic source signal suitable for transmission through the opaque material, at least one electromagnetic signal detector adapted to receive reflected electromagnetic energy signals from discontinuities in the opaque material encountered by the electromagnetic source signal, and a reflected electromagnetic energy signal processor suitable for determining a presence of obstructions and/or strata variations within the opaque material. The system is preferably integral with a head element suitable for traversing the opaque material, for example a subterranean drill bit.

Assignee:

Underground Imaging Technologies, Inc. - Latham NY

International Classification:

G01S 13/88
G01V 3/12

US Classification:

342 22, 342 27, 34235708

Abstract:

A mobile geophysical instrument produces geophysical data sets each associated with a position computed by use of a position sensor. A variable time delay results between a time when data for each geophysical data set is collected and a time when a position associated with each geophysical data set is recorded. A module receives distance transducer data and includes circuitry configured to generate a module signal based on trigger signals from the distance transducer and a calibration value. A data acquisition system (DAS) receives geophysical data sets from the geophysical instrument, positioning data from the positioning sensor, and the module signals. The DAS generates a DAS timestamp in response to each module signal and associates the DAS timestamp with each geophysical data set and a position associated with the geophysical data set, so as to substantially eliminate the variable time delay.

International Classification:

B65H009/00

US Classification:

271226000

Abstract:

Disclosed are systems and methods for de-skewing media when using an automatic media feeder comprising a registration guide and a registration tab disposed to cooperate with the registration guide in providing de-skewing of media when an edge of the media passes over the registration tab and is deflected thereby toward the registration guide.

International Classification:

G06T 15/10

US Classification:

345427000, 345419000

Abstract:

A user interface includes a display for displaying of a plurality of sensor data sets representative of signals associated with a plurality of sensors configured for sensing of a subsurface. At least some of the sensors are configured for subsurface sensing in a manner differing from other sensors of the plurality of sensors. Each of the sensor data sets comprises sensor data samples each associated with geographic position data. The sensor data sets are shown overlaid within a volume depicted on the display. The graphical representations of the sensor data sets are individually viewable within the volume and displayed in geographical alignment relative to one another within the volume in accordance with the geographic position data of the sensor data samples of each of the sensor data sets.
