Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Abstract: A first medical device for obstructive sleep apnea therapy includes therapy delivery circuitry coupled to a first set of electrodes implantable proximate to a first hypoglossal nerve within a tongue of the patient and configured to deliver a first electrical stimulation signal to the first hypoglossal nerve that causes the tongue of the patient to advance and includes information to communicate to a second medical device implantable within the head or neck of the patient and coupled to a second set of electrodes implantable proximate to a second hypoglossal nerve within the tongue of the patient; and sensing circuitry coupled to the first set of electrodes and configured to receive a second electrical stimulation signal, delivered to the second hypoglossal nerve by the second medical device, that includes information that the second medical device communicates to the first medical device.

Abstract: A controller for a drilling rig traveling block is disclosed utilizing an absolute position locator and a processor for employing various operating fixed and variable parameters for controlling the speed of travel of the traveling block. As approach limits are reached in either the ascending or descending mode, the position input enters the calculations so that the traveling block is effectively controlled at high speed while safely avoiding an upward or a downward collision. Operation, once the parameter are inputted, is independent of operator control except for override operation.

Abstract: Disclosed is an apparatus for continually monitoring for the presence of suspended or dissolved gas within a viscous material, such as in the material accumulated in the mud reservoir of a mud system used in an oil or gas drilling operation. Pressurized air is injected into the liquid to agitate and dislodge the gas. The dislodged gas is captured within a sealed chamber upon emerging from the liquid. A sample of the gas is continuously vented from the chamber through an outlet tube under the influence of the pressurized air. A gas sensor is mounted with the outlet tube so as to continually and accurately detect the presence of the gas within the liquid.
