In accordance with embodiments of the present disclosure, an information handling system may include a primary persistent memory comprising a volatile memory for storing data and a non-volatile memory for receiving data transferred from the volatile memory in response to a power loss of the information handling system. The information handling system may also include an alternate persistent memory instructions embodied in non-transitory computer readable media, the instructions for causing a processor communicatively coupled to the primary persistent memory and the alternate persistent memory to, responsive to a vulnerability of a persistence of the primary persistent memory, transfer application data from the primary persistent memory to the alternate persistent memory.

A numerical control system includes a numerical controller, an absolute encoder which detects a rotational displacement of a motor controlled by the numerical controller, batteries each of which supplies backup power to at least one of the numerical controller and the absolute encoder, A/D conversion circuits which analog/digital-convert voltages output from the batteries and output digital signals, the A/D conversion circuits being located in one device selected from the numerical controller and the absolute encoder and supplied with a backup voltage by the battery, and a display which displays the voltage values of the batteries on the basis of the above-mentioned digital signals and is located in the numerical controller.
