Abstract: The present application discloses a method and framework for drilling rig supervisory control automation that includes replication and aggregation of drilling rig supervisory control panels, a mechanism to manipulate the supervisory control panel parameters using one or more smart algorithms and a method and technique to access the supervisory control panels from a remote location. The system and method further includes recording, editing, and playing back a drilling rig's supervisory control parameter sequence during any typical drilling rig operation. Such a sequence includes recording all of the actions involved in a specific operation of the drilling rig operator. This sequence is saved, and can be edited to optimize the sequence, and further played back on the rig from which it was recorded, or on any other rig in the network.

Abstract: A methodology reduces the needed number of personnel on a rig by enabling performance of a variety of functions from a remote location. The method comprises utilizing a plurality of observation devices which monitor rig parameters remotely. Data from the observation devices is transmitted to a remote operations center used to analyze the data for determining operational changes to the rig. Control instructions may then be transmitted to the rig to implement the operational changes.

Abstract: A device that indicates an internal pressure of an inflatable medical cuff. The device includes a membrane movable in response to a difference between an internal pressure of the device and an external pressure. The device includes a movable internal pressure indicator. The movable internal pressure indicator is operably associated with at least a portion of the membrane.

Abstract: A portable wireless hearing testing device, the device including: left and right earpieces connected together by a headband and arranged as headphones; the left and right earpiece each including an earpiece housing shaped to surround the left and right ears of a subject respectively to substantially prevent ambient sounds reaching the ear of the subject; left and right loudspeakers located within the left and right earpiece housings respectively; and control circuitry located within the left and/or right earpiece housings and coupled to drive the loudspeakers, the control circuitry being arranged to produce left and right test signals which are applied to the left and right loudspeakers respectively, the test signals being operative to cause the left and right loudspeakers to provide a respective series of tones at frequencies corresponding to the test signals and wherein the test signals do not include significant harmonic components of the tones.

Abstract: An oxygenating device including: a body having: a first coupling spigot to which a collapsible bag is connected; an oxygen inlet to which a supply of oxygen can be connected for inflating, in use, the collapsible bag with oxygen; a second coupling spigot having a female leur socket for receipt in use of a male leur connector of an endotracheal tube or laryngeal mask; and a mask which can be applied, in use, about the nose and mouth of a patient and having an inlet/outlet socket mounted over the second coupling spigot.

Abstract: A hearing testing device (2) for self-testing the hearing of a subject including: an earpiece housing (4); a loud speaker (46) located within the housing; and control circuitry (14) coupled to drive the loudspeaker, the control circuitry being arranged to produce a sequence of test signals which are inputted to the loudspeaker to produce a series of tones at frequencies corresponding to said test signals wherein said test signals do not include significant harmonic components.

Abstract: A device for indicating an internal pressure of an inflatable medical cuff, comprising: a membrane movable in response to a difference between the internal pressure and an external pressure; and movable indication means operably associated with the membrane for indicating, in use of the device, the internal pressure.

Abstract: The disclosure allows a short runner valve or manifold tuning valve type manifold tuning device to retain sufficient force on the valve assembly in its closed state to eliminate any vibration or chatter from the system under normal engine operation. The disclosure also allows the device to be “pulsed” to the open or closed position; thus no electrical power is required to keep the system in one state. This is especially useful if activated times are extended due to certain engine operating conditions.

Abstract: An indicating device for indicating the number of times in which a surgical fitting has been autoclaved, the device including a body which includes first and second sets of teeth and a bimetallic indexing ring having teeth thereon, the arrangement being such that on thermal expansion and contraction of the indexing ring, its teeth engage those of the body so as to rotate the ring in a step wise manner relative to the body so as to thereby indicate the number of heat cycles to which the indicating device has been subjected, the indexing ring being the only movable part of the device.

Abstract: A multilingual agent of the present invention assists clients and users of clients in locating, accessing, and understanding documents on servers and also assists servers and providers of servers in making documents on the servers available to clients and users of clients, regardless of the languages in which the documents are written. A networked computer system in which the preferred embodiment of the present invention operates includes a client, a server, and a multilingual agent connected to one another via a network. The multilingual agent includes a document analyzer, a language identifier, a language converter, and a link modifier. In the operation of one aspect of the multilingual agent of the present invention, when the client retrieves a document from the server, the multilingual agent determines whether the document is written in a language that is unfamiliar to the user of the client.

Abstract: A device for use in ligament grafting includes a holder for receiving a ligament graft. A sheath is mounted over the holder in an expanded diameter state. The ligament graft is removed from the hollow body with the sheath so that the ligament graft is captured in the sheath in a reduced diameter state and a substantial length of the sheath extends from opposite ends of the graft.

Abstract: A disposable oxygenating device (2) comprising a body (4,40) and a collapsible bag (16) coupled thereto, the body including first coupling means (6) being couplable to a source of oxygen, second coupling means (10) being couplable to an endotracheal tube, laryngeal mask or the like, a connector (14) to which the bag (16) is connected, an oxygen duct (7) in fluid communication with the first coupling means having an outlet orifice (22) which in use delivers oxygen from the source of oxygen to inflate the bag with oxygen, and an outlet (20,44), the arrangement being such that, in use, during an inspiration cycle, oxygen from the bag passes through the second coupling means (10) and, during an expiration cycle, expiration products pass through the body (2,40) and are expelled through the outlet (20,44).

Abstract: A sheath (20) for containing a ligament graft (14) during connective tissue surgery, the sheath (20) being formed from bioabsorbable material and having a relaxed state and a stretched state, in which the length of the sheath (20) is substantially greater than the length in the relaxed state. A device for holding the sheath (20) and a method of utilizing the sheath (20) are also disclosed.

Abstract: Apparatus for maintaining tension on a ribbon in a printer used for transferring an image, e.g., thermally, from a print head through the ribbon to a print medium. By maintaining ribbon tension and thus keeping the ribbon essentially without wrinkles, print quality is enhanced. This tension maintenance apparatus uses a pair of torqued reel subassemblies with the ribbon extending between and is of particular significance when used in conjunction with a label stock as a printer medium when the printer mechanism bidirectionally moves the label stock to assist removal of labels from its backing. These torqued reel assemblies are sufficiently loaded such that ribbon tension is maintained between these reel assemblies despite this bidirectional movement.
