A system for determining a side of an electrical circuit exposed to a high temperature includes a printed circuit board having at least two outer edges and first and second board stiffeners of a first material disposed along the outer edges. The system also includes a control unit and a plurality of traces formed of a material that is different than the first material and has a second Seebeck coefficient. The control unit determines whether the first edge or second edge is closer to the high temperature based on a voltage differential between a trace connecting it to the first end of the first board stiffener and a trace connecting to the first end of the second board stiffener.

Differential and high rate of change temperature sensing circuit

A modular embedded controller includes an enclosure with an external interface, a generic motherboard, and an external device-specific input/output daughterboard. The generic motherboard has a supervisory processor and a plurality of daughterboard seats and is supported in the enclosure. The external device-specific input/output daughterboard is supported in one of the daughterboard seats, connects the external interface to the motherboard supervisory processor, and has an input/output processor translate data communicated between the motherboard supervisory processor and a device connected to the external interface. Embedded engine controllers and gas turbine engines with embedded controllers are also described.

Embedded controllers with modular architecture

A burst read control circuit acts as an interface to allow a burst-read capable device to execute burst reads from a page-mode capable memory device. The burst read control circuit coordinates burst read requests from the burst-read capable device and subsequent responses from the page-mode capable memory device by accessing subsequent and contiguous memory locations of the page-mode capable memory device.
