Abstract: An apparatus and method integrates optical transceivers for transfer of signals between optical and electronic media with surface mount packages, such as ball grid arrays and quad flat packs. A surface mount package is positioned directly beneath a modular optical transceiver. The surface mount package provides for electrically coupling external signals to the optical transceiver, so as to allow full performance functionality of data transfer components. An electrical coupling mechanism with high performance at high frequency is positioned between the surface mount package and the optical transceiver, electrically connecting them. In one implementation, the optical transceiver module is mounted directly to said surface mount package such that it is removable. In one embodiment, heat dissipation is provided by integral components and thermal vias, in addition to heat sinks.

Abstract: A method of fabricating a semiconductor package that may contain two or more dies. The method generally comprises the steps of (A) mounting a first die having a first side on an assembly apparatus and (B) mounting a second die having a second side and an adjoining third side on said assembly apparatus. The second die may be oriented such that (i) the second side and the third side both face the first side and (ii) the second side and the third side are both substantially nonparallel to the first side.

Abstract: An anchoring device for anchoring an oil well tubing string within an oil well casing. The device generally comprises a drive mandrel and an anchor mandrel. The drive mandrel has an upper end and a lower end, with the upper end releasably securable to an oil well tubing string. The anchor mandrel has an upper end that is releasably securable to the drive mandrel. The anchor mandrel is selectively engagable and disengagable with the interior surface of an oil well casing through the use of a plurality of rotatable slips. The slips have a gripping surface to contact and adhere to the interior surface of the oil well casing such that when the anchor mandrel is rotated in a first direction the slips are rotatably deployed to an engaged position with the gripping surfaces in contact with the interior surface of the oil well casing.

Abstract: A pump rod drive and torque release mechanism for use in association with a downhole pump positioned within a well. The pump rod drive and torque release mechanism comprises a central housing having a generally hollow interior, a drive shaft received within the central housing, a drive rod received within the central housing, and a torque transfer mechanism positioned within the central housing. The drive shaft may be operatively connected to a pump rod rotator to impart rotational movement to the drive shaft. The drive rod may be operatively connected to a downhole pump so as to enable transference of rotational energy from the drive rod to the downhole pump. The torque transfer mechanism has an engaged position wherein it operatively connects the drive shaft to the drive rod such that rotation of the drive shaft causes rotation of the drive rod. The torque transfer mechanism also has a disengaged position wherein it operatively disconnects the drive shaft from the drive rod.

Abstract: An apparatus for rotating a tubing string within an oil well. The apparatus includes an outer housing having an upper end, a lower end and a generally hollow interior where the lower end may be used to attach the outer housing to the casing bowl of an oil well. The apparatus further includes a drive assembly and a tubing string hanger generally disposed within the interior of the outer housing. The drive assembly has a generally hollow rotating gear mandrel and a drive gear. The tubing string hanger has a lower end for attaching to and supporting a tubing string. The tubing string hanger engages the rotating gear mandrel such that rotation of the rotating gear mandrel causes rotation of the tubing string hanger. The tubing string hanger, and a tubing string attached thereto, may be withdrawn from the oil well and through the outer housing without withdrawal of the rotating gear mandrel or the drive gear.
