Patent 7938773 was granted and assigned to Olympus Group on May, 2011 by the United States Patent and Trademark Office.
At startup, a main CPU renders and copies various types of unique parameters stored in an SRAM card corresponding to an ID unique to endoscopes to DPRAM and SDRAM and enables the endoscopes to be used with these parameters. Also in the event of desiring to change the set parameters, the user requests a change via an HMI, whereby the changed parameters are copied to the SDRAM via the DPRAM, and electrically-operated curving actions of the endoscope can be performed with the changed parameters.
