Abstract: Structures for a field-effect transistor and methods of forming a structure for a field-effect transistor. A first dielectric layer is deposited over a first gate structure in a first device area and a second gate structure in a second device area, and then planarized.

Abstract: A system for synchronizing central processing units (CPU) includes a schedule module that communicates a synchronization point, a first CPU that writes a first memory address to a first register in response to the first CPU reaching the synchronization point, and a second CPU that writes a second memory address to a second register in response to the second CPU reaching the synchronization point. The system further includes a first logical AND module that writes a first value to a third register based on the first and second memory addresses and a second logical AND module that writes a second value to a fourth register based on the first and second memory addresses. The system also includes a scheduler module that selectively generates a processor sync signal based on the first and second value.

Abstract: A dual redundant computer safety relay box system includes first and second fail-safe computing systems (FSCs) individually mounted to first and second printed circuit boards. Each FSC includes two computing modules (CPUs) designated as a first CPU and a second CPU. The first and second FSC's are both connected to a safety relay box. The printed circuit boards are isolable from each other permitting maintenance on one of the printed circuit boards while operation of the FSC of the other printed circuit board is maintained. In each FSC a health signal generated from the first and second printed circuit boards of the first and second CPUs defines a multi-level dynamic pulse signal. Presence of the dynamic pulse signal produces an output identified as each of a first and a second healthy indication signal from each of the CPUs of one of the first or second FSCs.

The system also includes a second FSC that continuously generates a second chassis health signal, that determines whether a copy of the data packet is valid, and that selectively determines whether to de-assert the second chassis health signal based on the determination. The system further includes a safety relay box module that determines whether to instruct the first FSC to operate in a predetermined mode based on the first chassis health signal and the second chassis health signal.
