  • Method and device for measuring a multiple-phase fluid flowing through a pipe
    Publication number: 20100064820
    Abstract: The invention relates to a method and device for measuring a multiple-phase fluid flowing through a pipe. The inventive method comprises the following steps in which: a fluid is illuminated using a first coaxial probe (32) placed in contact with the liquid phase (16) of the fluid and a first electromagnetic wave is emitted at a high frequency, the admittance at the interface between the rust probe (32) and the fluid is measured, and the fractions of at least two constituents of the liquid phase (16) are calculated in order to obtain the effective permittivity (?l) of said phase. Said method also includes the following steps in which: the fluid is illuminated using a second coaxial probe (50) and a second electromagnetic wave is emitted at a low frequency, the admittance at the interface between the second probe (50) and the liquid is measured, and the thickness (e) of the liquid is measured.

  • METHOD FOR SELECTIVELY IMPLEMENTING LOW THRESHOLD VOLTAGE TRANSISTORS IN DIGITAL LOGIC DESIGNS
    Publication number: 20100070933
    Abstract: A system and method for selectively replacing standard threshold voltage devices with low threshold voltage devices in a digital logic design. The system identifies at least one path having a first timing value, the path having a plurality of standard threshold devices. The path is reverse traversed, or otherwise analyzed or traversed, to identify at least one of the standard threshold devices to possibly replace with a corresponding low threshold device. The system also determines a timing value for the path associated with replacing the at least one standard threshold device with the corresponding low threshold device. Depending the analysis, the standard threshold device may be replaced with a low threshold device, such as when the path timing improves by replacement. Such replacement may be used in various paths, such as paths considered critical paths in a digital logic design.

  • APPARATUS AND METHOD TO PRESERVE ONE OR MORE LOGICAL COMMUNICATION PATHS IN A DATA PROCESSING SYSTEM
    Publication number: 20100070663
    Abstract: A method to preserve a logical communication path in a data processing system, that includes a host computer, a storage controller that comprises a first logical control unit (“LCU”), and a logical communication path that is in communication with the host computer and the first LCU, comprising deleting the first LCU and setting a first status for same. The method then configures a second LCU, and establishes a second status for same, wherein the second LCU includes all or a portion of the first LCU, but is not the same as the first LCU. The deleting, setting, configuring, and establishing are performed while maintaining the logical communication path, which is in communication with the second LCU.

    Abstract: In a method for processing a signal received by a receiver, at a first wireless receiver (20, 62) a first signal (x(t), x1(t)) comprising first and second signal components is received. The first signal component is intended for the first wireless receiver (20, 62) and the second signal component is related to at least one of a sending signal (s(t)) generated by a transmitter (29, 69) or to a second signal (x2(t)) intended for a second wireless receiver (61). To the first wireless receiver (20, 62) a reference signal (r(t), r1(t), r2(t)) which is proportional to the sending signal (s(t)) or to the second signal (x2(t)). At the first wireless receiver (20, 62) and from the reference signal (r(t), r1(t), r2(t)) an estimation signal which estimates the second signal component is generated.
