  • Patent number: 10345882
    Abstract: A dynamic power meter circuit receives a set of clock signals. The clock signals are summed by a clock sum adder, thereby generating a clock sum value. A dynamic power meter output value is generated based at least in part on the clock sum value. In one particular example, a dynamic power meter circuit receives clock signals and from them generates a clock sum model sub-value. The dynamic power meter circuit also receives event signals, and from them generates an architectural event model sub-value. A corresponding pair of clock sum model sub-value and architectural event model sub-value are then ratiometrically combined, thereby generating a dynamic power meter output value. Due to the use of both event signals and clock signals, a stream of dynamic power meter output values is generated that more closely tracks actual dynamic power of a circuit being monitored.

  • Patent number: 10310031
    Abstract: Described here are a system and method for designing radio frequency (“RF”) pulses for parallel transmission (“pTx”) applications, and particularly pTx applications in magnetization transfer (“MT”) magnetic resonance imaging (“MRI”). The concept of “SAR hopping” is implemented using a constrained optimization problem that simultaneously designs multiple RF sub-pulses to maximize power deposition in a bound proton pool while also minimizing local SAR across multiple bound proton pool excitation frequencies. This results in the set of RF waveforms that yield the best excitation profiles for all pulses while ensuring that the local SAR of the average of all pulses is below the regulatory limit imposed by the FDA. Pulses are designed simultaneously while constraining local SAR, global SAR, and peak voltage, explicitly.

The method includes acquiring coupling voltages for different tool face angles, between different antenna components of different axes of a transmitting station transmitting into the earth formation and different antenna components of different axes of a receiving station receiving from the formation, using the resistivity logging tool. Then, spatial Fourier coefficients are extracted from the coupling voltages, using a computing device associated with the resistivity logging tool. The relation between the resistivity logging tool and the casing is then determined as a function of the spatial Fourier coefficients and at least one resistivity measurement of the earth formation, using the computing device.

  • Patent number: 10254132
    Abstract: A sensor arrangement for determining at least one physical parameter of a sensor unit which is activated by at least one periodic excitation, comprising a detection region in which changes of the parameter in the surroundings of the sensor unit lead to an output signal from the sensor unit. The sensor unit is wired such that if there is no change of the parameter in the detection region the output signal is a zero signal at the output of the sensor unit, whereas if there are changes of the parameter in the detection region the output signal is a signal that is not zero and which has a specific amplitude and phase. By means of a closed-loop control, the non-zero signal in the receive path is adjusted to achieve an adjusted state at zero even in the presence of changes of the parameter in the detection region. Inherent in the control signal used for this adjustment is a deviation (?x, ?y) of the control signal from the adjusted state, which deviation represents information about the parameter.
