Abstract:
A system, method, and communication device are disclosed. The system can include an optical interrogator and a phase-modulating communication device. The communication device can include a retro-optimized lens, a phase modulator, and a processor. The retro-optimized lens can be a non-imaging optical arrangement configured to minimize deviation between an incoming signal and a reflected signal used for return link communications. The processor can be configured to calibrate a modulation path length of the communication device based on a wavelength of the communication signal and can control an operation of the phase-modulator to send phase-coded messages to the interrogator. Optionally, the processor can perform a real-time phase calibration of the communication device using feedback from the interrogator.
Abstract:
A method and a processing device are provided for detecting a hardware-based virtual machine environment. An execution time of a privileged instruction may be measured and an execution time of a nonprivileged instruction may be measured. The execution time of the privileged instruction may be compared with the execution time of the nonprivileged instruction. When the execution time of the privileged instruction exceeds the execution time of the nonprivileged instruction by at least a threshold or a threshold factor, then a hardware-based virtual machine environment is detected. In some embodiments, a well-known technique for detecting a software-based virtual machine environment may be used in conjunction with a technique for detecting a hardware-based virtual machine environment. A licensing policy of a software product may be accessed and the software product may be prevented from executing when a detected machine environment is in violation of the licensing policy.
Abstract:
A downhole device used to divert fluid flow out of a work string. The downhole device may be located at any point along a work string at which it may be necessary to divert the fluid flow to the annulus. The downhole device may be activated and deactivated by inserting a single deformable dart into the work string. The device catches the dart blocking fluid flow through the work string. Increased fluid pressure activates the device, which diverts the fluid flow out of the work string into the annulus. A locating sleeve with a continuous j-track allows the device to be retained in activated position. The dart is adapted to deform under a predetermined amount of fluid pressure allowing the dart past the device and returning fluid flow through the work string. The downhole device may be activated multiple times without removing the downhole device from the wellbore.
Abstract:
An non-skid coating comprising a two-part epoxy and a filler comprising particles of a thermoset resin provides a durable, low-weight, low-abrasive coating for decks and floors, especially for aircraft carrier flight decks. The coating has the further advantage of having lower heavy metal content than current aluminum-based, non-skid coatings.
Abstract:
This invention relates to improvements in products and processes for cleaning up oil, chemical, or other hydrocarbon spills, and cleaning up the environment where such spills have occurred. In one aspect of the invention, there is provided an adsorbent polymeric composition which is oleophilic and capable of adsorption of other chemicals and hydrocarbons from both land and water, the adsorbent composition including polyethylene/vinyl acetate copolymer, catalyst, cross-linking agent, lubricant, blowing agent and a bulking agent. In a second aspect of the invention there is provided a method of manufacture of an adsorbent composition for use in retrieving and recycling oil, chemicals and hydrocarbons from land or water environments.
Abstract:
A system (100) and method (600) is provided for self-scaling generic policy tracking. The system can include a policy key (210) on a client (132) for scanning the client for at least one configuration, assessing a policy compliance based on the configuration, and reporting at least one policy state to a policy server. The system can also include a policy server (110) for receiving the at least one policy state from the policy key, and configuring network access to the client based on the at least one policy state. The policy key can report at least one policy state (232) on a periodic communication cycle that can be scaled according to system load for increasing system capacity.
Abstract:
Organic compounds are removed from contaminated soil, ground water and the like by treatment with a combination of a water soluble peroxygen compound, such as sodium persulfate, and a pH modifier capable of maintaining a pH greater than about 10, such as a metal hydroxide.
Abstract:
A configuration tool for a content and distribution management system for assets (111, 112), comprising: a. an editor (101) for editing templates defining metadata (161, 162, 163; 171, 172, 173) of an asset (111; 112) through key/value pairs and lists of values; b. a plurality of agents (121, 122, 123, 12N), each having headend device specific logic for transforming an internal asset format into a headend device specific asset format; c. an extensible representation of metadata, e.g. XML, for uninterpreted transport of device specific assets to the appropriate agent (121; 122; 123; 12N); and d. a configurable workflow (151) for defining the order and dependencies between elements of events handling the assets (111; 112) and/or metadata (161, 162, 163; 171, 172, 173).
Abstract:
A method for providing remote access to a computer environment provided by a virtual machine includes the step of receiving authentication information associated with a user of a client machine. Based on the received authentication information, a computer environment provided by a virtualized operating system and already associated with the user is identified. A connection is established between the client machine and the identified computing environment
Abstract:
Disclosed are systems and methods enabling a user to select optimal parameters for a printing job. The systems and methods disclosed are directed to facilitating the adjustment of printing parameters based upon at least the knowledge of a particular aspect of a printing environment (e.g., printer) and further including the ability to dynamically adjust parameters in relation to dynamically adjustable parameters, wherein the parameters may be determined as a function of other specified parameters.
