Abstract: A flexible pipe joint has a body and an annular elastomeric flexible element flexibly coupling an extension pipe to the body and operable to pivot the extension pipe with respect to the body. The flexible pipe joint also has an annular flexible boot operable to thermally or chemically insulating the annular elastomeric flexible element from the fluid flowing through a lumen of the flexible pipe joint. The annular flexible boot encircles the lumen, and the annular flexible boot has a first annular end attached to the extension pipe and a second annular end mounted so that pivoting of the extension pipe with respect to the body causes a flexing of the annular flexible boot, and a majority of the annular flexible boot has a shape conforming to shape of neighboring components of the flexible pipe joint.

Abstract: In view of the above, there has been described a load compensator including one or more tension spring assemblies that are contained within a tubular housing when tension from a load is applied to the tension spring assemblies. When the load compensator includes more than one tension spring assembly, the tension spring assemblies are mechanically connected to each other in series and stacked in-line with each other in the housing. In a preferred construction, each of the tension spring assemblies includes elastomeric tension elements mounted between two disks, and the tubular housing includes a tube having threaded ends and caps that screw onto the tube.

Abstract: For load compensation, different kinds of elastomeric load compensators are placed at various locations on the crane for increased flexibility and for shock and vibration absorption. The elastomeric load compensators employ elastomeric tension elements, elastomeric torsion elements, or elastomeric shear elements. Elastomeric tension elements can be simply inserted in series with the main hoist rope. An elastomeric load compensator employing elastomeric torsion elements is mounted to the underside of the boom for receiving the live end of the main hoist rope. A single stack of elastomeric shear elements is suitable for mounting a hoist or winch or an idler sheave to the crane structure. For additional load compensation, the hoist, winch, and idler sheaves are mounted on rails for increased displacements under heave loads, and the increased displacements are compensated by elongated elastomeric tension elements or multiple elastomeric tension, torsion or shear elements in series.

Abstract: A telescopic joint for a marine drilling riser has an outer barrel and an inner barrel defining a central lumen for passage of a drill pipe string. The inner barrel is received within the outer barrel, and there is a clearance fit between the barrels for sliding of the inner barrel with respect to the outer barrel while maintaining a coaxial relationship between the barrels. A tubular rolling elastomeric membrane is disposed within the outer barrel and has one end secured to an outer circumference of the inner barrel and another end secured to an inner circumference of the outer barrel for sealing drilling fluid within the central lumen. As the inner barrel slides with respect to the outer barrel, the elastomeric membrane rolls with respect to the inner barrel and the outer barrel so that wear of the seal due to abrasion is eliminated.

Abstract: A process for verifying the playback of media content on a display includes receiving a digital representation of at least a portion of media content playing on the display, comparing the received digital representation to media content that was scheduled to play on the display from which the digital representation was captured and verifying the playback of the received digital representation if the received digital representation matches the compared media content. The process can further include soliciting a viewer of the display to capture a digital representation of at least a portion of the media content being presented on the display and to communicate the captured digital representation to an advertised location.

Abstract: The present invention provides for a self-correcting state circuit. A first flip flop is configured to receive a clock input and a first data input, and to generate a first output in response to the clock input and the first data input. A second flip flop is coupled to the first flip flop and configured to receive the clock input and to receive the first output as a second data input, and to generate a second output in response to the clock input and the first output. A first correction circuit is coupled to the second flip flop and configured to generate a corrected output. A third flip flop is coupled to the first correction circuit and configured to receive the clock input and to receive the corrected output as a third data input, and to generate a third output in response to the clock input and the third data input.

Abstract: The present invention provides for state correction. A first value in a state circuit is received from a flip flop. The received value is transmitted to a second flip flop. The received value within the second flip flop is altered if an error condition arises. The received value is transmitted to a third flip flop. In one aspect, the received value transmitted to the third flip flop comprises an unaltered received value. In another aspect, the received value transmitted to the third flip flop comprises transmitting an altered received value. This allows for an incorrect state within the state machine to change to a correct state after a few clock pulses.

Abstract: The present invention provides for state correction. A first flip flop coupled to a second flip flop. A state correction circuit coupled to the output of the second flip flop. A third flip flop is coupled to the output of the state correction circuit. A fourth flip flop is coupled to the output of the third flip flop.

A comparator is coupled to the division selection line. A first synchronizer coupled to the output of the latch. A frequency divider is coupled to the output of the synchronizer. A second synchronizer is coupled to the output of the comparator and the output of the frequency divider. There is feedback between the output of the second synchronizer and the enable input of the latch, the reset of the first synchronizer, the reset of the second synchronized, and the reset of the divide by n divider.
