Abstract: Embodiments of the present invention relate to a volumetric compensating annular bellows used to compensate two fluid volumes by an annular displacement. This is achieved using a bellows welded on to a tube with a varying shape radius. A bellows is arranged within the annulus and is deformable in an annular direction in response to fluid volume expansion. The bellows can be used in several oilfield applications for fluid compensation.

Abstract: A field joint for connecting a plurality of downhole tool modules is disclosed. The modules include a housing and an electrical line. A bulkhead is coupled to a first module that includes a first conduit aperture for receiving an electrical connector assembly. The first electrical connector assembly is releasably coupled to the exterior portion of the first module and includes a first connector having a first end adapted for electrical coupling to an electrical line. A connector block is coupled to the second module that includes a second conduit aperture positioned to substantially face the first conduit aperture when the first and second modules are joined. A second electrical connector is disposed in the second conduit aperture and is electrically coupled to an electrical line such that an electrical contact is established with a second end of the first connector when the first and second modules are joined.

Abstract: A field joint used to connect downhole tool modules. The field joint includes a bulkhead, a connector block, and various electrical connections. The bulkhead couples to a first tool module and has a first connection face, which partially defines an exterior of the first tool module and has a first conduit aperture that receives an electrical connector assembly. An electrical connector assembly received in the first conduit aperture is releasably coupled to the exterior of the first tool module, and includes a first connector. The connector block is coupled to a second tool module and has a second connection face defining a second conduit aperture positioned to face the first conduit aperture when the tool modules are joined. A second electrical connector disposed in the second conduit aperture establishes electrical contact with the first connector when the first and second tool modules are joined.

Abstract: An access point in a wireless communication system can be configured to include multiple virtual LANS (VLANs) based on security levels, thereby allowing secure traffic to be isolated from insecure traffic. Configuring the access point can include assigning a security level to each VLAN and setting a security association for each station associated with the access point. Based on this security association, each station can be assigned to an appropriate VLAN.

Abstract: A method for encrypted communications between a first transceiver and a second transceiver is provided. The method includes sending from a first transceiver to a second transceiver a request to initiate derivation of a new encryption key. The request to initiate a new encryption key derivation includes an exchange threshold indicative of when the new encryption key is to be used to encrypt communication packets.

Abstract: There is disclosed a laminate panel and a process for production thereof. The laminate panel comprises a core layer disposed between and bonded to each of a first metal layer and a second metal layer. The core layer comprises a porous layer substantially encapsulated by a thermoplastic resin. An advantage of the present laminate material is that it can withstand paint/bake cycles while maintaining a desirable balance of physical properties (e.g., peel strength, stiffness, impact resistance and the like). Another distinct advantage of the present laminate panel is its formability. This allows for the use medium or deep draw forming techniques to facilitate production of parts having a variety of shapes and radii (e.g., 90° bends, draws, stretches, multi-shape configurations and the like) for vehicular applications.

Abstract: A display device 8 such as a flat screen television may be stowed away out of sight within a cabin by partly recessing into a moulded coaming 3 forming part of the boat's superstructure 1 in addition to being partially received in a special housing 7. In this way, the fact that a display device 8 is hidden out of view is made less obvious because the housing 7 does not conform to the shape of the display device 8.

Abstract: A probe for establishing fluid communication between a downhole tool and a subterranean formation is provided. The downhole tool is positioned in a wellbore penetrating the subterranean formation. The probe includes a platform operatively connected to the downhole tool, at least one packer operatively connected to the platform, the packer having at least one hole extending therethrough and at least one embedded member disposed in the packer for enhancing the operation of the packer as it is pressed against the wellbore wall.

Abstract: A wearable garment including a front panel and an interconnected rear panel. Each of the panels exhibits a substantially rectangular shape and is constructed of an absorbent material, such as terrycloth or the like. Inter-engaging button and snap fasteners are located in spaced apart fashion along opposing and extending side edges associated with the front and rear panels and to conjoin the front and rear panels together. A hood is constructed of a moisture absorbent material and extends from between the front and rear panels, an aperture being defined within the hood such that it covers a head and neck of a wearer of the garment. In an alternate embodiment, the hood is substituted by a substantially “V” shaped aperture.
