20100108401 | Resilient Bit Systems and Methods - The present invention relates to drill bits and methods of making drill bits. In one embodiment, a drill bit includes a bit body having at least one independent blade, in which the blade is attached to the bit body by way of a piece that is attached to a force absorbing material. In another embodiment, a drill bit includes an integrated blade, in which the blade is cut into segments allowing the segments of the blade to independently flex. | 05-06-2010 |

20150060141 | DOWNHOLE MOTOR SENSING ASSEMBLY AND METHOD OF USING SAME - A downhole sensing assembly for sensing motor parameters of a downhole motor positionable in a wellbore penetrating a subterranean formation is provided. The downhole motor has a stator and a rotor rotatable within the stator. The sensing assembly includes at least one rotor extension operatively connectable to the rotor and movable therewith, at least one marker positionable about the rotor extension, and at least one motor sensor positionable about a downhole tool and operatively coupled to the marker to detect movement of the marker whereby motor parameters, such as rotational speed of the motor, are detectable. | 03-05-2015 |

20130112486 | Resilient Bit Systems and Methods - A drill bit for subsurface drilling includes a body, a blade extending from the body, and a flex cut behind the front side of the blade to allow at least a portion of the blade to flex. The drill bit may include a void cut disposed behind the front side of the blade and intersecting the flex cut. A void cut is larger in one dimension than is the flex cut in that dimension. | 05-09-2013 |
20140174827 | Drilling Systems and Fixed Cutter Bits with Adjustable Depth-of-Cut to Control Torque-on-Bit - A drill bit for drilling a borehole in an earthen formation includes a connection member having a pin end. In addition, the drill bit includes a bit body coupled to the connection member and configured to rotate relative to the connection member about a central axis of the bit. The bit body includes a bit face. Further, the drill bit includes a blade extending radially along the bit face. Still further, the drill bit includes a plurality of cutter elements mounted to a cutter-supporting surface of the blade. Moreover, the drill bit includes a depth-of-cut limiting structure slidably disposed in a bore extending axially from the cutter-supporting surface. The depth-of-cut limiting structure is configured to move axially relative to the bit body in response to rotation of the bit body relative to the connection member. | 06-26-2014 |

20090173534 | I/O CONNECTORS WITH EXTENDABLE FARADAY CAGE - An apparatus providing one or more I/O connections to a computer. The apparatus includes a Faraday cage generally about a flex cable, or other computing element, that may translate when the I/O ports to the computer are utilized. The embodiment maintains the Faraday cage for the flex cable or element as the I/O port housing opens or closes. | 07-09-2009 |

20140268900 | POWER SUPPLY WITH CONTINUOUS SPREAD-SPECTRUM SWITCHING SIGNAL - A switched-mode power supply with reduced electromagnetic interference (EMI) is described. This switched-mode power supply includes a modulation circuit that continuously frequency modulates a control signal over a bandwidth associated with a spread-spectrum modulation signal. By frequency modulating the control signal in the switched-mode power supply, spectral content associated with a modulated switching signal is spread evenly over the bandwidth, thereby reducing the EMI. | 09-18-2014 |
