Abstract: A method for forming a diamond product. Diamond material is provided and a damage layer comprising sp2 bonded carbon is formed in the material. The presence of the damage layer defines a first diamond layer above and in contact with the damage layer and a second diamond layer below and in contact with the damage layer. The damage layer is electrochemically etched to separate it from the first layer, wherein the electrochemical etching is performed in a solution containing ions, the solution having an electrical conductivity of at least 500 ?S cm?1, and wherein the ions are capable of forming radicals during electrolysis. The diamond product is also described.

Abstract: A patient monitor configured to receive patient-information electrical signals from an invasive patient sensor and a minimally invasive patient sensor, the patient monitor including a base unit and a detachable user interface unit for displaying hemodynamic parameters determined by the base unit. The base unit and user interface unit can be docked together, tethered together through a cabled connection, or physically separated from one another using wireless communication to transmit and receive information. The base unit and the user interface unit may pair before the user interface unit displays data to link the base unit with the user interface unit. The patient monitor can be configured to switch between invasive and minimally invasive monitoring of hemodynamic parameters of a patient, using invasive measurements to calibrate minimally invasive measurements.

Abstract: An embodiment provides a device for measuring pH in an aqueous sample, including: at least one measurement electrode comprising a first carbon region, wherein the carbon region comprises a single pH sensitive carbon region, wherein the single pH sensitive carbon region of the measurement electrode is a sp2 carbon region of a boron doped diamond-based pH electrode; at least one reference electrode; at least one auxiliary electrode; and a memory storing instructions executable by a processor to identify a pH of an aqueous sample by measuring an electrical potential between the at least one measurement electrode and the at least one reference electrode. Other aspects are described and claimed.

Abstract: Energy may be stored, converted, and generated during a drilling operation. An example method includes receiving fluid energy from a flow of drilling fluid (115) in a borehole (105). The received fluid energy may be stored as mechanical energy in an energy storage device (205) in the borehole (105). Additionally, electrical energy may be generated from the mechanical energy using a generator mechanically or magnetically coupled to the energy storage device.

Abstract: Methods and systems for large-scale airframe assembly are disclosed. In one embodiment, a method includes measuring a plurality of discrete point positions at least one of on and adjacent to at least one of a first and a second component, and measuring at least one surface position on the at least one of the first and second components. The measured positions are compared with a desired position information (e.g., a computer aided design model). The comparison may include applying a fitting routine to the measured positions and the desired position information. Next, a transformation matrix for improving the comparison between the measured positions and the desired position information is computed. At least one of the first and second components is then moved according to the transformation matrix. During movement, the plurality of discrete point positions may be monitored and provided to the position control system by a feedback loop.

Abstract: A ball-throwing machine is provided which may be used for throwing baseballs, softballs and the like. The machine includes a power head having at least two and preferably three coacting wheels for propelling a ball toward a batter to simulate a pitch. Three AC motors and companion motor drives are provided for causing the wheels to rotate at predetermined speeds. The motor drives include dynamic braking circuits to permit rapid deceleration of the wheels. A pair of linear actuators is provided to permit the power head to be moved to predetermined horizontal and vertical positions. A programmable controller is included for individually controlling the rotational speed of each individual wheel, the horizontal position of the power head and the vertical position of the power head. A smart card reader may be employed for programming of the controller and the machine is adapted to be used in conjunction with a video display to simulate the actual pitching of a baseball by a pitcher.
