Publication number: 20130239650Abstract: A device is described for use in performing an inground operation. An accelerometer is supported by the device for generating accelerometer readings that characterize the inground operation subject to a native temperature drift of the accelerometer. A set of compensation data is developed and stored for use in compensating for the native temperature drift. The compensation data is applied to the accelerometer readings to produce compensated accelerometer readings that externally compensate for the native temperature drift to yield an enhanced thermal performance which is improved as compared to a native thermal performance of the accelerometer. A seven position calibration method for a triaxial accelerometer is described. An air module is described which isolates the accelerometer of the device at least from a potting compound that at least fills otherwise unoccupied volumes of the device interior.Type: ApplicationFiled: March 14, 2013Publication date: September 19, 2013Applicant: Merlin Technology Inc.Inventors: Albert W.

Publication number: 20120196463Abstract: A hostile environment electrical housing, associated endcap and method are described. A housing body is electrically conductive and defines a housing opening that leads into a housing cavity. An elongated electrically conductive member can be resiliently captured between the housing to form a plurality of electrical contacts between the housing body and the endcap as part of an electrical circuit. A spring can be fixedly engaged to the endcap by a crimping arrangement that is integrally formed with the endcap. An endcap assembly including the endcap and the elongated electrically conductive member can be provided for installation on a pre-existing housing body.Type: ApplicationFiled: January 30, 2012Publication date: August 2, 2012Inventors: Mark H.

Patent number: 6666365Abstract: A micro device feeder is provided which is adjustable to accommodate micro devices supplied on tapes with different widths. A mounting plate has a movable drive plate slidably mounted thereto. An input mechanism on the movable drive plate receives micro devices contained in a tape. A sprocket engages and advances the tape under motor drive. A feeder width adjustment mechanism allows for movement of the movable drive plate relative to the mounting plate for adjusting the sprocket to accommodate tapes with different widths where the distance between the tape and sprocket centerlines change. The feeder width adjustment mechanism includes a pin coupled to the mounting plate, a securing device coupled to the movable drive plate and is capable of moving along the pin, and a locking mechanism capable of securing the securing device to the pin to lock the movable drive plate relative to the mounting plate.Type: GrantFiled: December 21, 2001Date of Patent: December 23, 2003Assignee: Data I/O CorporationInventor: Dmitry Feldman

Patent number: 4867255Abstract: There is disclosed herein an apparatus for providing an underground tunnel utilizing a steerable pneumatically powered, elongated percussive downhole hammer having a forwardmost cutting bit which is asymmetrically configured with respect to the elongation axis of the hammer. This hammer is steered through the ground, that is, made to move along a straight path or a particular curved path, by controlling the way in which it is pneumatically powered and/or the way in which it is urged forward and/or the way in which its cutting bit is rotated.Type: GrantFiled: May 20, 1988Date of Patent: September 19, 1989Assignee: FlowMole CorporationInventors: Glen O.
