COORDINATE MEASUREMENT MACHINE WITH REDUNDANT ENERGY SOURCES

摘要

An articulated arm coordinate measurement machine is provided with a power supply having multiple power sources. The power supply having an input configured to receive electrical power from an external energy supply and first and second energy storage members. The first energy storage member having a first processing circuit configured to measure at least one first parameter and transmit a first signal to the first electronic circuit. The second energy storage member having a second processing circuit configured to measure at least one second parameter and transmit a second signal to the first electronic circuit. Wherein the power supply is configure to selectively transfer electrical power from at least one of the first and second energy storage members, the power supply further being configured to change the transfer of electrical power from the first and second energy storage members in response to the first signal and second signal.
