摘要:
An interface module between a communication module and a number of instances of business logic modules of a software engine comprises first and second functional elements. The first functional element receives incoming data from the communications module and selects which of the instances of business logic modules to forward the incoming data based upon a rule set held within a data structure at the first functional element. The incoming data passes to the selected logic module instance via the second functional element. The second functional element determines either a single shot or a multiple shot mode of operation. If a multiple shot mode of operation is selected incoming data passes to the selected logic module instance sequentially. Alternatively, if a single shot mode of operation is selected a summary data record corresponding summary of incoming data received at the first function element passes to the selected logic module instance.
摘要:
A method for managing an energy consuming load in a group of energy consuming loads and a method for managing the group of energy consuming loads. The method includes generating sets of load state data from the loads, making enablement state decisions for one or more loads independently of the other loads using the sets of load state data, and implementing the enablement state decisions. An apparatus for managing an energy consuming load in a group of energy consuming loads, including a transmitter for transmitting a set of load state data generated from the load, a receiver for receiving sets of load state data from other loads, a processor for processing the sets of load state data to make an enablement state decision for the load, and a controller for implementing the enablement state decision.
摘要:
A U-shaped elevator (100) having no doors is provided with first and second latching mechanisms (102, 104) which when contacted by the tubular to be entrapped within the elevator (100) move from a closed position to an open position and which then return to a closed position as soon as the tubular is entrapped within the elevator (100). The latching mechanisms (102, 104) have a safety catch (120) which prevents the tubular from being inadvertently removed from the elevator (100). The release of the safety latch mechanism (120) can only be activated by a handle (170) which is manipulated by hand by personnel working on the derrick utilizing the elevator (100).

The invention concerns a system for converting digital video broadcast data into a form adapted to their reception by one or more wired or radio receivers comprising: means for receiving digital video broadcast data consisting of elementary streams and signaling data; means for identifying which elementary streams are required by one or more wired or radio receivers; means for detecting and extracting the signaling data and any of the required elementary streams of received digital video broadcast data; and means for dynamically transmitting the extracted elementary streams to the wired or radio receivers.
摘要:
A method of managing power consumption in a device such as a video image processing device for processing data from one or more pixels forming a frame of an image, the method comprising the steps of determining one or more regions of interest in the image, identifying one or more pixels located in said one or more regions of interest, processing the one or more identified pixels in a predetermined manner and switching off the power for at least part of the device when the transmitted pixel data are not amongst the one or more identified pixels for a predetermined period of time.
摘要:
A drive shoe (10) for penetrating soil is a larger size than a conductor pipe (11) and connected to the bottom section of the conductor pipe. An exterior band (40) is mounted on the outer diameter and proximate the lower end of the drive shoe. Teeth (28) are spaced at a predetermined interval and extending form and forming the bottom of the drive shoe to enhance penetration into earth formations. The teeth (28) are formed by cutting a beveled section such that the bevel is angled from the drive shoe outer surface towards the drive shoe inner surface. The drive shoe may also have an inner band (41) mounted on the inner surface to further compress the soil away form the interior surface of the drive shoe.
摘要:
A drillable, anti-rotation device (10) for limiting the rotation of a downhole tool, such as a cement plug, when drilling out the downhole tool. The drillable, anti-rotation device (10) comprises a drillable sleeve (12) connected within a non-drillable outer tubular member (20) connected within a pipe string. The sleeve (12) has one or more grooves (46) or other indentation, and/or one or more ribs (14) or other protrusions extending inwardly within the interior of the device for gripping or otherwise retarding the rotation of such downhole tool.
