20090268936	POSITION SENSING APPARATUS AND METHOD FOR ACTIVE HEADWORN DEVICE - An active headworn device that includes a position sensing device used to determine whether the headworn device is in an extended state upon a user's head or in a contracted state off of the user's head. The position sensing device may be coupled with a microcontroller adapted to power up or power down the active headworn device based on a signal from the position sensing device. The position sensing device may various devices such as a Hall-effect device used in combination with a magnet or a LED in combination with a detector. The movement of the headworn device between positions changes the distance between components of the position sensing device such that the device signals the microcontroller to power up or down the active headworn device. The microcontroller may mute a portion of circuitry prior to the powering up or down the active headworn device to prevent undesirable feedback.	10-29-2009

20110024194	SYSTEM AND METHOD FOR ONE-TRIP HOLE ENLARGEMENT OPERATIONS - A drilling assembly for simultaneous hole enlargement operations comprises a drill bit, an adjustable diameter reamer, and a hole opener. The reamer is coupled with, and positioned uphole from the drill bit. The reamer is adjustable between a first diameter and a second diameter that is larger than the first diameter. The hole opener is coupled with, and positioned uphole from the reamer.	02-03-2011
20110166837	Reamer and Bit Interaction Model System and Method - Teachings of the disclosure are directed to a reamer and/or bit interaction model system and method. The method may include receiving performance data regarding a cutting structure, and calculating a characteristic curve, using the performance data. The characteristic curve may be weight-based and/or torque-based. The method may also include storing the characteristic curve. In particular embodiments, the characteristic curve may include either weight on cutting structure or torque on the cutting structure, as a function of the rate of penetration.	07-07-2011
