Abstract: A unitary gravel pack multi-pathway tube includes a body; a gravel slurry flow passage defined within the body; and a control line protection projection extending from and supported by the body, the projection extending laterally from the body relative to an extent of the flow passage and method.

Abstract: A gravel pack multi-pathway tube includes a body and a flow passage at the body. Further, the tube includes a projection at the body, the projection receptive to a control line. A gravel packing device component wherein the component includes a shroud, a multi-pathway tube at the shroud, and a projection appurtenant the multi-pathway tube, the projection being receptive to a control line. A method for running and protecting a control line at a gravel pack component, which includes running a component into a wellbore wherein the component includes a shroud, a multi-pathway tube at the shroud, and a projection appurtenant the multi-pathway tube, the projection being receptive to a control line and inserting a control line at the projection.

Abstract: A ball design for withstanding high differential pressures without leakage features a circumferential groove near the circle of contact on the ball with a surrounding seat. High differential forces are transmitted beyond the circle of contact so that deflection due to applied differential pressures results in flexing in the groove area while maintaining full circumferential seat contact to prevent leakage.

Abstract: A system for enabling the hearing impaired comprises a plurality of servo actuators each associated with a particular segment of a predetermined frequency domain. The servo actuators drive tactile stimulators which engage the skin of the hearing impaired person in patterns that are unique to individual inputs thereby enabling the hearing impaired person to “hear” signals within the defined frequency domain. An electromechanical system for enabling the visually impaired comprises a two dimension array of servo actuators which respond to optical sensors and which actuate tactile stimulators thereby identifying objects in the path of the visually impaired person.

Abstract: Disclosed is a workstring for use in a gravel packing system. The workstring includes a washpipe with at least one port and a selectively openable and closeable closure mechanism in operable communication with the at least one port. Further disclosed is a collet having a collet base and a plurality of collet fingers extending from the collet base. At least one of the collet fingers includes retaining feature, the retaining feature being configured to yield under bending at a selected valve. Yet further disclosed is a method for gravel packing. The method includes gravel packing a wellbore including opening one or more valves in a washpipe as pressure associated with the gravel packing climbs, the valves providing an escape path for a fluid component of the gravel pack to an inside dimension of the washpipe. The method further includes closing the one or more valves in the washpipe.

Abstract: Desired portions of a balloon may be marked by varying the texture of the surface. Marking the balloon facilitates positioning of the balloon on a catheter and facilitates positioning a medical device on the balloon.
