Abstract: One or more embodiments disclosed herein relate generally to flotation devices, and more specifically to modular flotation devices with a mechanism to removably attach to other modular devices. In one embodiments, an apparatus includes a first flotation module and a first connector coupled to the first flotation module. The first connector has a first end portion, a second end portion and a sidewall extended from the first end portion to the second end portion. The sidewall defines a plurality of circumferentially defined stepped portions configured to matingly engage a second connector of a second flotation module to couple the first flotation module to the second flotation module. The first connector is selectively operative as one of a female connector or a male connector with respect to the second connector.

Abstract: A wellbore isolation assembly including a plurality of discrete components each having an inner bore with a center axis, the plurality of discrete components axially abuttable such that each of the inner bores align to form a common bore, the plurality of discrete components including a fixing element; and a sealing element; wherein the plurality of discrete components are integrable by a setting device receivable through the common bore, and wherein application of a compressive force to the plurality of discrete components urges the fixing element and the sealing element to radially extend, relative to the axis of the common bore.

Abstract: A wellbore sealing assembly including a downhole device with a sealing sleeve coupled to the uphole end. The downhole device has an internal channel allowing fluid communication through the device that is substantially blocked when a ball is seated in the sleeve. The walls of the sleeve are elastically or plastically deformable, and are shaped to be deformed when the ball is seated. When deformed, the walls are in contact with the wellbore surface substantially blocking fluid communication around the device. Elastically deformable walls of the sleeve may further include a plastically deformable layer on its inner surface that, once deformed by the seating of the ball, keep the elastically deformed walls in contact with the wellbore surface when the ball is not seated.

Abstract: A steerable endoscopic tool uses concentric sleeves of varying curvature to steer a tool tip toward or in the direction of a location of surgical interest. By rotating and/or axially displacing such sleeves relative to one another the tool tip may be maneuvered within a current field of view with several degrees of freedom without any physical movement of an endoscope, thus facilitating improved surgical access and control without complex mechanical systems in the endoscope or at the surgical site.

Abstract: A wellbore anchoring assembly including a downhole device, a collar, and one or more deformable locking arms attached to the collar wherein the locking arms extend in a direction substantially along the longitudinal axis of the collar. The downhole device having a first component, the surface of the first component having a first protrusion. Each of the locking arms being deformable away from the longitudinal axis, one or more gripping protrusions extend out from an outer surface of the locking arms, and at least one second protrusion extends from an inner surface of the locking arms. The inner surface is engageable with the surface of the first component to deform the locking arms away from the longitudinal axis. Upon engagement, the at least one first protrusion engages the at least one second protrusion to secure the collar to the downhole device.

Abstract: A roofing system of the present disclosure has a first shingle layer and an overlaid layer a portion of which overlays the first shingle layer. Additionally, the roofing system has a first shingle in the first shingle layer, the first shingle having a first channel and a first protrusion in an upward-facing surface and the channel is contiguous with the protrusion, the channel and the protrusion formed on an interlocking end of the first shingle. Further, the roofing system has a second shingle in the overlaid layer, the second shingle having a second channel and a second protrusion in a downward-facing surface and the second channel is contiguous with the second protrusion such that the first channel is configured for receiving the second protrusion and the second channel is configured for receiving the first protrusion.

Abstract: Various embodiments include methods and apparatus structured to control access from a casing in a borehole. A tool can be provided to allow flow from an inner diameter of a casing to external to the casing based on an alterable material structured as a portion of the tool. The alterable material can be structured as a dissolvable material or a degradable material. Additional apparatus, systems, and methods can be implemented in a variety of applications.
