摘要:
Media content to be place shifted is received at the local user device along with a place shift enabled parameter that contains data associated with the received media content and that indicates whether the received media content is authorised to be place shifted. A user command to place shift the received media content to the remote user device is also received. It is then determined, by analysing the place shift enabled parameter, whether the received media content is authorised to be place shifted and based on this determination the place shifting of the received content to a remote device is allowed or impaired.

A downhole device used to divert fluid flow out of a work string into an annulus. The downhole device is activated by the movement of a plurality of pistons within the downhole device. Fluid flow through a restriction of the downhole device creates an increase in fluid pressure causing the movement of the pistons. The pistons move a flow tube between various locations within the device. In one location, the flow tube prevents fluid flow to the annulus while in another location the flow tube allows fluid flow to be diverted into the annulus. The downhole device may include a locating sleeve having a continuous j-track allowing the flow tube to be selectively retained at the various locations within the downhole device. Fluid flow through the downhole is used to cycle the device between diverting fluid flow to the annulus and forcing fluid flow down the work string.
摘要:
A system and method for decreasing the protocol processing incurred by an NFS (Network File System) client, and the network bandwidth consumed, when multiple NFS requests are issued close in time to each other. Requests received close in time to each other within one NFS client are aggregated into a single communication packet, even if they are from different NFS users, processes or applications. The per-request overhead of the NFS requests is thus avoided, and multiple streams of requests may be merged into one. When a first request is received by the client, it may be delayed for a short time to determine whether any other requests can be sent at the same time. NFS requests may be aggregated on an NFS client from multiple applications, processes, users or other entities. An NFS client may include an aggregator or other mechanism for performing the aggregation.

A method for estimating power capability of a power source driving an electrical load can include obtaining initial values of power source parameters including a voltage value and a current value while preventing the power source from causing kinetic energy to be produced in the electrical load. The method can also include estimating power capability of the power source based on the initial values of the power source parameters.

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.
摘要:
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.
摘要:
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.
摘要:
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.

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).
