Appl. No.:

10/099873

Inventors:

Michael R. Wells - Lakewood CO, US
Luc Van Puymbroeck - Kingwood TX, US
Holger Stibbe - Humble TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 49/02
E21B 10/02
E21B 10/61

US Classification:

175 58, 175393, 175404

Abstract:

A core bit for cutting core samples in subterranean formations. The core bit has interior geometric features configured to control the quantity of drilling fluid, or flow split, flowing into a narrow annulus defined by an inside diameter of the core bit and an outside diameter of a core shoe. Reducing the flow split minimizes fluid invasion of a core being cut; thus, the core bit provides increased core quality and recoverability. The core bit is also adaptable for use with conventional core barrel assemblies and conventional coring techniques.

International Classification:

E21B 10/60

US Classification:

175393, 175340, 175429, 175424

Abstract:

A nozzle for use on a rotary drill bit for forming a subterranean borehole includes a body and at least one passageway extending through the body from an inlet to an exit aperture. The passageway has a converging region and a diverging region. At least a portion of the diverging region of the fluid passageway is substantially bifurcated. A rotary drill bit for forming a borehole in a subterranean formation includes at least one such nozzle installed within a body of the bit and configured for communicating drilling fluid to a face of the body. A method of communicating fluid to a face of a drill bit includes introducing fluid into a passageway, causing the fluid to flow through a converging region, causing the drilling fluid to flow through a diverging region, and substantially bifurcating the drilling fluid at least within a portion of the diverging region.

International Classification:

E21B 10/43

US Classification:

175398

Abstract:

An earth boring drill bit design for alleviating balling varies the junk slot depth in junk slots subject to balling from the other junk slots. Using variable depth bit bodies enhances the hydraulic characteristics of the bit as well as assists in the placement of the nozzles for machining purposes. This flexibility optimizes the area changes along the ducts required by the bit's operation.

International Classification:

H04N 7/18

US Classification:

348143

Abstract:

A method of displaying video surveillance system information is disclosed. Video clips associated with events are represented by event cards. The event cards include frames selected from the video clips associated with the events. Event cards include metadata, and can be annotated. Display of overlapping event cards causes a compressed event card to be displayed. Selection of a compressed event card dynamically expands the compressed event card to display a paneled event card.

Appl. No.:

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 10/38
E21B 10/60

US Classification:

175429, 175431, 175340, 175393

Abstract:

The blades of a PDC bit have a nozzle between them preferably oriented laterally across the plane of the cutters on the blade and more preferably in a trough disposed adjacent the row of cutters. The cutting is less likely to adhere to the bit surface because the trough abruptly spaces back the bit surface and the spray being oriented radially preferably into the trough gets between the bit surface and the cutting before it can adhere to the bit surface using the fluid energy to drive the cutting into the junk slot.

US Classification:

175430, 175378, 175426, 175434

Abstract:

A downhole drill bit includes, a body, a plurality of cutters attached to the body, and at least one prefabricated splitter having a proximal portion and at least one distal portion. The proximal portion is encased within the body and the at least one distal portion extends outwardly of the body. Further the at least one distal portion is in operable communication with at least one of the plurality of cutters such that the at least one distal portion bifurcates cuttings cut by the at least one cutter.

US Classification:

348143, 348152, 348154, 348155, 348699

Abstract:

A method and apparatus is described for specifying regions of interest within a two-dimensional view of visual information that comprises a series of frames. Visual changes that occur in the view are stored. A user enters search criteria that specify at least one first region of interest within the view and a visual change. A visual change may include a change in pixel values or a detection of motion of one or more objects within the view. The first search criteria are compared against the stored visual changes to identify a sequence of frames in which the specified visual change occurred within the first region of interest. The search criteria may specify multiple regions of interest, each with one or more types of visual changes. If a motion is specified, then a direction, speed, and behavior of a moving object may also be specified.

International Classification:

US Classification:

455415, 455566, 4554143, 455418

Abstract:

A caller information server provides caller identification (ID) information to a mobile device. The server receives caller ID information from local address books stored on multiple mobile devices. The caller information server aggregates the received caller ID information to generate a pooled address book. The caller information server may determine whether names within the caller ID information are legitimate and store or filter the information accordingly. When a mobile device receives a call from a telephone number for which it lacks caller ID information in its local address book, the mobile device sends a request for the caller ID information for the telephone number, to the caller information server. The server identifies caller ID information associated with the telephone number in the pooled address book, and sends this information to the mobile device.
