Abstract:
An optical fiber management system for a remotely operated vehicle (ROV) includes a spool containing a length of optical cable, a motor coupled to the spool, a motor controller, a speed sensor and a feed mechanism. The motor controller can detect the speed of the ROV through water and control the rotational speed of the motor so that the optical cable is removed from the spool at a speed that is equal to or greater than the speed of the ROV. A feed mechanism is used to apply a tension to the optical cable so that it is removed from the spool and emitted from the ROV without becoming tangled.
Abstract:
A downhole actuator apparatus that selectively maintains a pressure differential between two pressure regions in a well. The apparatus includes a body defining first and second chambers. A piston is slidably disposed in the body and is selectively moveable between first and second positions. A barrier is disposed in the body to selectively separate the first and second chambers. A fluid is disposed in the first chamber between the barrier and the piston. A control system that is at least partially disposed within the body is operable to generate an output signal responsive to receipt of a predetermined input signal. The output signal is operable to create a failure of the barrier such that at least a portion of the fluid flows from the first chamber to the second chamber and the piston moves from the first position to the second position.
Abstract:
A method and system to maintain a personal health record, including, obtaining data using a medical imaging device, storing the data in a picture archiving and communication system, determining which of the data stored in the picture archiving and communication system is to be stored in the personal health record, and transmitting the data to be stored in the personal health record to an internet accessible storage device based on the determination.
Abstract:
Techniques are provided that control the generation of test routes to improve the ability of a test system to isolate defects on programmable circuits. A test generator creates test routes that test the horizontal resources. In these test routes, the inputs of each circuit element are only connected to other circuit elements in the same row. Test routes are also generated to test the vertical resources. Each of theses test routes is allowed to make only one transition from between two different rows of circuit elements. The configuration generator includes a post processor that ensures all source drivers in the test routes connect to at least two sinks.
Abstract:
Methods and structures for protecting programmable logic device (“PLD”) programming files are disclosed. In one respect, an embodiment of the present invention includes applying a particular protective setting to a PLD, the setting has a relationship to proper programming of the PLD. A configuration program generates programming data including a non-pre-processed and a pre-processed portion. The pre-processed data reflects the results of processing that is carried out off-device (e.g. by the configuration program on a user computer), but is consistent with the logic of certain on-device processing circuitry. The pre-processing also takes into account information regarding the particular applied setting. The non-pre-processed portion of the programming data is further processed by the certain on-device processing circuitry. The output of the on-device processing circuitry is combined with the pre-processed portion of the programming data in a bit stream for programming the PLD. In another respect, some embodiments utilize a PLD redundancy scheme for implementing programming data protection.
Abstract:
A system and method of damping fluid pressure waves in a subterranean well. In a described embodiment, pressure waves are damped by positioning a dampener in the well during a perforating operation. The dampener may attenuate the pressure waves by absorbing the pressure waves, flowing the pressure waves through viscously damping material, generating complementary pressure waves, changing a material phase, or by a combination of these methods.
Abstract:
A bridging fault detection system allows for a high amount of test coverage using a low number of test configurations. The bridging fault detection system automatically creates optimal test configurations and test vectors without the need for precise layout information, and is adaptable to complex programmable device architectures. Testers can specify a precise level of testing coverage to optimize the testing processing. A programmable device with interconnect bias circuitry decreases the number of test configurations and thus the time needed to test for bridging faults. The interconnect bias circuit provides explicit test control over the unused lines in a configuration, driving them both high and low for complete test coverage between each line and all of its possible neighbors. The bridging fault detection system balances the available number of control test points against the number of interconnect segments stitched together by programmable connection to maximize the lines under test per configuration.
Abstract:
A downhole oil and water separator for an oil well includes a water-selective membrane disposed in a production flowpath of the well. The water-selective membrane is operable to selectively pass water from the production flowpath to a disposal zone to increase the concentration of oil in the production flowpath at the surface.
Abstract:
A method for creating a mask-programmed device from a preexisting design of a source device is provided. The method includes creating a netlist from a user defined circuit configuration file, configuring logic resources on the mask-programmed device produce basic logic elements, and generating a custom interconnect based on the netlist that interconnects the configured logic resources to produce the desired logic design.
Abstract:
An improved method of simulating the testing of integrated circuits is provided. A database of desired connections between a tester unit and a DUT for different downbonds is accessed by a multiplexer which sets up the desired connections. The system automatically makes the correct connection for each downbond without manual intervention from the user as was required in traditional simulator systems.
