Abstract: A system and method for automatic recovery of a firmware image is disclosed. The method can include creating a shadow firmware image in a storage device from a firmware image in non-volatile memory. It is determined whether an abnormal event affecting the firmware image has occurred. The shadow firmware image is recovered from the storage device. The shadow firmware image is copied to the non-volatile memory.

Abstract: A hardware-based fan controller for controlling fan modules in a computer system having multiple computer nodes is disclosed. Each of the computer nodes has a service processor. The fan controller includes a slave module that receives fan speed commands from each of the service processors. A fan speed generator is coupled to the slave module and a subset of the fan modules. The fan speed generator receives fan speed commands from the slave module and fan speed outputs from the subset of fan modules. The fan speed generator is configured to output a speed command to each of the fan modules in the subset.

Abstract: A system and method for logging state data from a power system control device on a computer system is disclosed. The computer system includes a power system supplying power to the computer system. The power system has a power-up sequence having a plurality of stages. The power system control device is coupled to the power system. The power system control device includes a finite state machine circuit having states corresponding to the stages of the power-up sequence. The control device also has a write controller, a storage buffer, and a communication interface. The write controller writes the state of the finite state machine circuit in the storage buffer. An external controller is coupled to the communication interface and is operable to read the stored state data.

CPC classification number: G01K11/006 , H05K1/181 , H05K7/04 , H05K2201/10151 , H05K2201/10181 , H05K2201/10363
Abstract: A system includes a first printed circuit board (PCB), a temperature sensor, a switching circuit provided on the first PCB, and a controller. The temperature sensor is configured to measure temperature of at least an area of the first PCB. The controller is configured to trigger the switching circuit to turn off power to the first PCB, based at least in part on the temperature sensor detecting a temperature above a temperature threshold. The system is able to disrupt power much faster than conventional methods of power protection which may have a blind spot to certain areas of the first PCB, since these methods rely on power disruption when a maximum power is sensed.

Abstract: A junction between two circuit board segments can be made using a flexible printed circuit board (PCB), permitting the two circuit board segments to be movably positioned with respect to one another, while maintaining electrical connections between the board segments through the junction. Such a design with flexible PCB junctions can allow a single, foldable board with multiple board segments to be used in place of a set of multiple circuit boards that must couple together using connectors and cables.
