摘要:
A property of fluid within a well in a geological volume is controlled. The property of the fluid may include fluid density, pressure gradient, temperature, foaming characteristics, and/or other fluid properties within the well. In particular, the fluid property is controlled discretely within different sections (e.g., at different depths) of the well. This may enhance the structural stability of the well.
摘要:
A method of controlling a vehicle engine system is described. The method involves sensing a pressure in the engine; generating a signal indicative of the sensed pressure; encrypting the signal to generate an encrypted data message containing information indicative of the sensed pressure; transmitting the encrypted data message to an engine control means; decrypting the encrypted data message to obtain the information indicative of the sensed pressure; and controlling the vehicle engine system in dependence upon the information contained in the encrypted data message. A pressure sensor for use in the method, and a suitably programmed electronic control unit are also described.
摘要:
A fluid accumulator arrangement suitable for use with a compression ignition internal-combustion engine comprising a first storage volume, a second storage volume, and valve means fluidly connected between the first storage volume and the second storage volume. In one embodiment, the valve means is a three-way control valve wherein, in a first position, the first storage volume communicates with the second storage volume, in a second position the first storage volume is isolated from the second storage volume and, in a third position, one of the first or second storage volumes communicates with a low pressure drain. The arrangement may also include control means to operate the valve means in accordance with predetermined control strategies.

摘要:
Retroreflective sheeting includes a body layer having a structured surface with recessed faces forming cube corner cavities. A reflective film is disposed at least on the recessed faces, and a fill material fills the cube corner cavities. The fill material comprises radiation-curable materials, adhesives, or both, and preferably transparent radiation-curable pressure-sensitive adhesives. The fill material preferably forms a continuous layer covering both the recessed faces and upper portions of the structured surface. A transparent cover layer preferably contacts the fill material layer.
