Latest Patents
One of Southworth's latest patents is titled "Interrupts between asynchronously operating CPUs in fault tolerant." This invention describes a computer system configured for fault tolerance, utilizing three identical CPUs that execute the same instruction stream. The system employs two identical, self-checking memory modules that store duplicates of the same data. Memory references are made through three separate busses connected to the memory modules, allowing for loosely synchronized operations among the CPUs. The patent also details how interrupts can be synchronized to ensure all CPUs implement them simultaneously.
Another significant patent is "Printer escapement servomotor drive with a minimum power supply." This invention provides a servomotor drive system designed to minimize power supply requirements for printer escapements. The system features a fixed current source applied to a servomotor, with mechanisms for accelerating and decelerating the printhead escapement. It includes feedback control to adjust the motor current according to a preselected varying current profile, thereby optimizing power consumption.
