Abstract: A calibration apparatus for calibrating a compass and/or tilt sensor module includes a longitudinal support having a support axis; a first longitudinal member coupled to the longitudinal support to be rotatable around the support axis relative to the longitudinal support and a second longitudinal member connected to the first longitudinal member to be rotatable around a second longitudinal member axis relative to the first longitudinal member. The second longitudinal member axis is perpendicular to the support axis. A third longitudinal member is coupled to the second longitudinal member to be rotatable around a third longitudinal member axis relative to the second longitudinal member, rotatable with the second longitudinal member relative to the first longitudinal member, and rotatable with the first longitudinal member relative to the longitudinal support. The third longitudinal axis is perpendicular to the second longitudinal member axis. The module is connected to the third longitudinal member.

Abstract: In one embodiment, an apparatus for installing a sensor device to achieve a known magnetic orientation includes a distal tilt sensor configured to be attached to the sensor device to be installed into a borehole; an installation tool configured to be detachably connected to the sensor device at or near a distal end of the installation tool to install the sensor device into the borehole; and an orientation sensor configured to be attached to the installation tool at a location proximal of the distal end of the installation tool toward a proximal end of the installation tool, the orientation sensor including a compass and a proximal tilt sensor.

Abstract: The method and system disclosed herein allow pressure profile data to be collected remotely from multiple autonomous sensors without entering the blast radius. The system obtains a GPS synchronized time value for detonation and obtains subsequent synchronized pressure data sets overtime from multiple independently functioning remote and correlates that data from each transducer with the initial detonation event.

Abstract: A method and apparatus for preventing water from entering the abrasive port of an entrained high pressure fluid jet nozzle and a method and apparatus for attaching the high pressure fluid jet nozzle to a hazardous duty robot. The invention includes the application of a positive air pressure to an abrasive line preferably during those times when there is insufficient vacuum generate by high pressure fluid being sent through the restricted orifice in the high pressure nozzle. The invention prevents clogging of a fluid jet cutting system during operation. The invention includes mounting a nozzle and/or visualization system to an expandable and contactable component such as a grasping device that allows for continued use of the expandable and contractible grasping unit. This includes, for example, a grasping device that is provided out the end of a movable robot arm and that allows for rotation of the grasping device.

Abstract: Target capable of producing a desired infrared signature of an intended target object. Heated gas is transported through a thermal system. Gas leaks out of the system at locations constructed of gas-permeable material. Gas-permeable locations are selectively placed to create the desired infrared signature of the intended target object.
