A system for protection, control, metering, and monitoring of the delivery of electrical power is disclosed. Embodiments of the system provide input / output devices called bricks to receive analog and binary field data from primary equipment located in a power substation switchyard. The bricks are linked via fiber-optic patch cables and patch panels with one or more intelligent electronic devices (“IEDs”). In operation, the bricks convert the received binary and / or analog field data into digital signals, and transmit the digital signals synchronously to their associated IEDs using clock signals provided by each IED to the individual bricks. The bricks may accept a computer software code download from each of its master IED(s). Multiple code implementations, each tailored to the requirements of its master IED(s) can therefore co-exist on a single brick.

There is provided an LC resonance type oscillation circuit with a wide frequency variable range with a small variation of Q and capable of reducing a chip size due to no external parts required, and a communication semiconductor circuit device (high-frequency IC) having the oscillation circuit. In the LC resonance type oscillation circuit, a capacitance element and a switch element are connected in parallel between both terminals of a secondary side inductance element which is placed facing an inductance element constituting the LC resonance circuit and is connected by mutual induction to the inductance element. It is designed so that an equivalent inductance increases as the capacitance element is connected between the both terminals of the secondary side inductance element in a state where the switch element is turned OFF, and that the equivalent inductance decreases as the both terminals of the secondary side inductance element are short-circuited in a state where the switch element is turned ON.

Methods for correcting inhomogeneities of magnetic resonance (MR) images and for evaluating the performance of the inhomogeneity correction. The contribution of both transmit field and receiver sensitivity to signal inhomogeneity have been separately considered and quantified. As a result, their negative contributions can be fully corrected. The correction method can greatly enhance the accuracy and precision of MRI techniques and improve the detection sensitivity of pathophysiological changes. The performance of signal inhomogeneity correction methods has been evaluated and confirmed using phantom and in vivo human brain experiments. The present methodologies are readily applicable to correct signal intensity inhomogeneity artifacts produced in different imaging modalities, such as computer tomography, X-ray, ultrasound, and transmission electron microscopy.

A dielectric layer (e.g., an interpoly dielectric layer) is deposited over low and high voltage devices of a peripheral memory device. The dielectric behaves as an oxidation and wet oxide etch barrier. The dielectric prevents the devices from being stripped by a wet oxide etch that can result in the exposure of the silicon corners. The exposure of a silicon corner may increase thinning of a gate oxide at the field edge. This causes variability and unreliability in the device. The dielectric is not removed from a device until the device is ready for processing. That is, the dielectric remains on a device until the growing of a gate oxide on that device has begun. This reduces the exposure of the silicon corner. Hedges that result may be removed by exposing a trench in the field oxide at the hedge.
