Abstract: The present invention includes a method and apparatus that allows languages to send, receive and manipulate structures defined by other languages. Structurally, the present invention includes a preprocessor and a runtime library. The preprocessor accepts, as input, source code written in a high-level language, such as C or C++. The preprocessor produces, as output, a series of Java classes. Each Java class describes a structure defined in the input source code. Java programs use the descriptions produced by the preprocessor to send, receive and manipulate structures the structures defined in the input source code.

Abstract: A computer system having a power supply monitoring arrangement employs a number of comparators for detecting whether or not various supply voltages produced by the power supply for use in the computer are above or below a reference level, or whether an overcurrent condition exists. These detected conditions are used to determine whether or not the power supply should be shut down, or during power-up to determine whether the initialization routine can be started by the CPU. Delays are included to prevent an undervoltage condition from indicating shut down of the power supply during power-up.

Abstract: A switching rectifier power supply circuit has a power MOS transistor connected in series with half of the primary of a center-tapped transformer, and has rectifiers in series with an inductive load on the secondary side. The gate of the power transistor is driven by a pulse source which is pulse-width modulated in response to the load voltage, and also controlled in response to the current through the power transistor. To prevent leading-edge current spikes due to turn-on of the power transistor from adversely affecting the pulse-width modulator, yet allow trailing-edge current spikes due to transformer saturation to be compensated for, an inhibit circuit is included in the control path responding to current through the power transformer.
