Abstract: A method for steering a downhole tool includes receiving an electromagnetic (EM) signal from the downhole tool. The downhole tool is in a wellbore in a formation. The EM signal comprises a gap voltage and a gap current that are measured across a gap sub in the downhole tool. The method also includes determining a gap impedance based at least partially upon the gap voltage and the gap current. The method also includes determining a first formation resistivity at a first location in the wellbore based at least partially upon the gap impedance. The method also includes steering the downhole tool based at least partially upon the first formation resistivity.

Abstract: For controlling an orifice of a valve (10) in an HVAC system (100) to regulate the flow (?) of a fluid through a thermal energy exchanger (2) of the HVAC system (100) and adjust the energy transfer rate ({dot over (Q)}) of the thermal energy exchanger (2) in response to a demand value (d), the orifice of the valve (10) is controlled in a first mode of operation where the flow (?) of the fluid through the thermal energy exchanger (2) is regulated within efficiency constraints on the energy transfer rate ({dot over (Q)}) with respect to an efficiency threshold value. Upon receiving an override signal (OS), the orifice of the valve (10) is controlled in a second mode of operation where the flow (?) of the fluid through the thermal energy exchanger (2) is not regulated with respect to the first efficiency threshold value.

Abstract: Communication between the surface and a downhole location, such as a bottomhole assembly and/or an RSS is performed by electromagnetic downlink. Electromagnetic signals are transmitted from the surface through the formation at a frequency of 8 Hz or greater. Electromagnetic signals are transmitted and received while drilling or during drilling activities. In this manner, information and instructions may be transmitted to the BHA while drilling.

Abstract: A method for placement of electrodes includes determining spatial distribution of a signal caused by generating an electromagnetic field in an instrument disposed in drill string used to drill a wellbore. The electromagnetic field comprises encoded measurements from at least one sensor associated with the instrument. Voltages induced by noise are measured across at least one pair of spaced apart electrodes placed at a plurality of positions spaced apart from a surface location of the wellbore. A spatial distribution of noise is estimated using the measured voltages. Positions for placement of at least two electrodes are selected using the spatial distribution of signal and the spatial distribution of noise.

Abstract: Described are methods for treating a keratinized tissue condition in a subject in need thereof. The method may include providing the subject including the keratinized tissue condition. The method may include conducting one or more treatment cycles on the keratinized tissue. Each treatment cycle may include contacting the keratinized tissue with an acid-activated gas-generating composition.

Abstract: A printer that may be part of a point of sales terminal. The printer includes a latching mechanism that helps hold the printer's cover in the closed position when latched, but allows the cover to open when unlatched. The latching mechanism is automatically moved to an unlatched state by reversing the paper feed motor. Related methods of operating a printer are also disclosed.

Abstract: A computer implemented method, data processing system, and computer usable program code are provided for detecting a printer condition. A set of signals is received from a sensor in a printer. A current state of a paper roll within the printer is detected within the set of signals. Responsive to the current state indicating that the paper roll moved from a desired position between a set of devices, a response signal is sent to the user of the printer. Alternatively, in response to the current state indicating that the paper roll moved from the desired position, a number of paper line feed commands that are issued are counted. A determination is made as to whether the number of paper line feed commands that are issued exceeds a predetermined value. Responsive to the number of paper line feed commands exceeding the predetermined value, the response signal is sent.
