Abstract: A magnetic component includes a first monolithic core structure having a plurality of magnetic layers and at least one nonmagnetic layer separating one of the plurality of magnetic layers from another of the plurality of magnetic layers. A first opening extends through the first core structure, and a conductive element establishes a conductive path through the first opening, wherein the nonmagnetic layer separates the conductive element from one of the magnetic layers.

Abstract: A workspace security system having processors, sensors, and actuators for local and remote monitoring, control, and automation of physical and environmental security, safety, efficiency, and productivity. The system includes passive and active access authentication devices and active or passive unlocking and lockdown of office furniture components, work sites, and facilities. The system may include multilevel authentication credentials, automatic lockdown of office furniture and other components based on the proximity of credentials, and video or other imaging systems to detect and record motion.

Abstract: A method and apparatus for automated bidirectional integration of peripheral data sources for a production tool couples the system components together in a web-based arrangement. The process tools and the peripheral data sources are configured as websites to provide information to the system. Certain components of the system are also configured as browsers to obtain available information and use this information to make decisions and perform actions.

Abstract: Two pulse-width modulated power supplies are synchronized to operate at 180.degree. of phase shift to reduce the peak amplitude of the instantaneous current drawn from the DC input bus. The circuit includes means for disabling the synchronization upon detection of an undervoltage fault condition on the output of either supply. This feature allows frequency programming techniques to be used to provide foldback current limiting for either supply without affecting the operation of the other supply.

Abstract: Overvoltage and component failure protection for redundant current-mode controlled power supplies operating in parallel takes a supply off line when the supply drives the output bus to an overvoltage condition, without removing properly functioning supplies from the bus. The supply is also taken off line when either the error amplifier or the PWM fails.

Abstract: A pulse-width modulated DC-DC power supply is illustrated with overvoltage protection which upon initial detection momentarily shuts down the pulse-width modulating portion of the control loop for a given cycle. If the overvoltage condition persists for more than a prescribed number of cycles or amount of time, the power supply is shut down permanently. The delay between momentary and permanent shut down being used to allow system operation to be maintained with minimal damage (voltage induced load stress) where large voltage transients may be temporarily introduced into the system.
