In one embodiment of the invention, a method for providing security to a device, includes: reading a visitor pass to determine if the visitor pass is valid; if the visitor pass is invalid, then preventing access to a device by use of the visitor pass; and if the visitor pass is valid, then permitting access to the device by use of the visitor pass. If the visitor pass is valid, then access may also be permitted to a designated network by use of the visitor pass.

A wellbore device is provided which includes a fluid passage for transferring fluid between an earth formation and a surface facility, and a body transferable from a first mode to a second mode upon contact of the body with a selected fluid. The body is arranged so as to substantially close the fluid passage upon transfer of the body from the first mode to the second mode due to contact of the body with the selected fluid.

A rotary slip for supporting a drill string having a plurality of slip segments connected to define an opening for insertion of the drill string, wherein each slip segment comprises a head region, a toe region, and an inner radial surface axially extending between the head and toe regions, and wherein the inner radial surface of each slip segment comprises a circumferential groove. A plurality of axially aligned drill string gripping inserts are attached to each slip segment between the head region and the circumferential groove, wherein each insert comprises a gripping surface for contacting the drill string. A load ring is disposed within the circumferential groove of each slip element, the load ring comprising at least one securing element which is engaged by one of the plurality of axially aligned inserts to secure the load ring within the circumferential groove.

An implantable dual chamber ICD and method senses atrial (A-A) and ventricular (V-V) intervals, calculates the ratio (A/V interval ratio) of A-A intervals to V-V intervals, classifies heart rhythms with V-V intervals (i) above a revert rate threshold as not tachycardia, (ii) below a high rate threshold as treatable tachycardia, (iii) between the two thresholds and below an A-dominant A/V interval ratio threshold as a non-treatable tachycardia, (iv) between the revert rate threshold and the high rate threshold and above a V-dominant threshold as treatable tachycardia and, when the heart rhythm is intermediate all four thresholds, (v) utilizes one or a combination of advanced discriminators (e.g., ventricular windowing, ventricular interval variability, sudden onset, AV-delay creep, ventricular electrogram morphology, active sensing, minute ventilation, or right ventricular pressure) to classify whether the heart rhythm is a non-treatable or a treatable tachycardia.
