Abstract: Some embodiments include a sensor assembly comprising a sensor to be carried by a movable component movably positionable about a tool body of a downhole tool. The sensor is to take wellsite measurements and the downhole tool is positionable in a wellbore. The sensor assembly further includes electronics positionable in the movable component. The electronics are to electrically connect to the sensor to receive the wellsite measurements from the sensor, and the wellsite measurements are usable to determine wellsite parameters.

Abstract: A sensor assembly for a downhole tool including a tool body and a movable component movably positionable about the tool body is disclosed. The sensor assembly may include a wear sensor and/or a position sensor. The wear sensor may include a core with conductors at various depths to send a signal, whereby, upon wear of the core, a change in the signal at the depth of the wear is detectable. The position sensor may be carried by the movable component, and may be used with references comprising magnets distributed about the tool body. The position sensor includes magnets having polarity responsive to polarity of the references whereby a position of the movable component is determined. The sensor assembly may also include a chassis housing electronics coupled to the position sensor and/or the wear sensor.

Abstract: 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.

Abstract: A drill bit for subsurface drilling includes a body; a blade extending from the body and having a front, a back side, and a formation facing surface between the front side and the back side. The blade is configured to have a plurality of cutting elements mounted to it. In addition the drill bit includes a first flex cut extending into the blade from the formation facing surface and positioned between the front side and the back side of the blade. The first flex cut is configured to allow at least a portion of the blade to flex.
