摘要:
In a digital system with a processor coupled to a paged memory system, the memory system may be dynamically configured using a memory compaction manager in order to allow portions of the memory to be placed in a low power mode. As applications are executed by the processor, program instructions are copied from a non-volatile memory coupled to the processor into pages of the paged memory system under control of an operating system. Pages in the paged memory system that are not being used by the processor are periodically identified. The paged memory system is compacted by copying pages that are being used by the processor from a second region of the paged memory into a first region of the paged memory. The second region may be placed in a low power mode when it contains no pages that are being used by the processor.

An overspeed protection device includes at least one torque measurement unit supported by an output shaft coupled mechanically to a free turbine of a turbine engine and a signal processing unit able to transmit to a turbine engine regulating system a command to reduce a flow of fuel injected if it is detected that the torque has dropped below a first datum value. The signal processing unit is shaped to command a reduction of the flow if it is detected that the torque has dropped below a first datum value, the torque measurement used to trigger the reduction being taken during a rotation corresponding to a fraction of a revolution of the output shaft.

The invention relates to an aqueous base formulation for cleaning rugs, fabrics, carpets, and the like. The formulation is composed of seventy-eight point five percent water, to which is added tetrapotassium pyrophosphate at ten percent of the formulation. A nonionic surfactant, ethoxylated glycery) ricinoleate, is then added at three percent. An isopropyl alcohol is then added at three percent. A fifth product, propylene carbonate, is introduced at five percent. Finally, sodium cumene sulphonate is added at zero point five percent. All these products are inserted with mechanized stirring so as to allow complete homogenization. There are no side effects for the user and the environment.
摘要:
An apparatus for successive refinement of video frames, and methods of operating the same result in reduced latency for downloading the video frames. The apparatus for transmitting video frames comprises a plurality of video frames encoded to provide a plurality of program modules. A first program module provides a first video frame. A second program module provides an enhancement to the first video frame. A cataloging resource which provides scheduling requests for transmission of the plurality of program modules requests the first program module and the second program module for transmission. An output driver which transmits program modules receives the scheduling requests from the cataloging resource for the first program module and the second program module and selects the first program module and the second program module for transmission to produce a higher quality first video frame.

A process for cross-linking (co)polymers having ester functions involves reacting a polyalcohol-derived polyester and a polyacid-derived polyester in the presence of an alkaline alcoholate at a temperature in excess of 180.degree. C.
摘要:
A water-gate is intended to withstand pressure exerted by a liquid. The water-gate includes an essentially flat shell plate and a plurality of thin cores extending along the length of the shell plate, the thin cores being substantially parallel to one another. Each core is solidly connected to the shell plate and pierced with multiple disjoint holes. According to the disclosure, the water-gate comprises at least one stiffener formed by assembling multiple elements that are aligned along a longitudinal axis of the stiffener and that each extend between the cores without passing through the cores. Each element may be solidly connected to a face of at least one core around one of the holes.
摘要:
A centrifugal pump driven by mechanical coupling with an engine has a low pressure inlet receiving fuel from a fuel circuit of an aircraft, a high pressure outlet connected to a regulator circuit for regulating the flow rate of fuel supplied to the engine, and an assistance pump unit that is electrically controlled, having an inlet connected to the aircraft fuel circuit and an outlet connected to the flow rate regulator circuit so as to deliver, via its outlet, fuel that is at a predetermined minimum pressure, the pressure of the fuel supplied to the regulator circuit being the higher of the pressures delivered by the centrifugal pump and the assistance pump unit.
摘要:
The invention a method of forming complex shape of styrenic polymer foams in which a pressing surface is created, for example, by planing/machining a layer of an as formed extruded styrenic polymer plank, contacting said plank with a contoured die face and pressing the foam to form the complex shape.
