have been obvious to locate the controls . . . within the compressor housing." (Id. at 5.)
The appellants argue, "given the complete lack of benefit across the prior art to make
such a modification, the combination is improper." (Reply Br. at 4.)
As aforementioned, although Persem uses the aforementioned microprocessor-
based small computer 56 as a controller for its refrigeration compressor system, the
reference does not address physical mounting of the controller. We have found that
the omission of such a detail and the recognition of modifications invites the use of
known techniques for mounting a controller.
For its part, Voss discloses a known technique of mounting a controller to an
"electrically powered refrigeration compressor[]." Col. 1, l. 6-7. To wit, "[c]ontrol
electronics for the motor are mounted within the housing and in communication with the
refrigerant loop. The control electronics are thereby cooled by the circulating refrigerant
mixture." Col. 2, ll. 10-13. Even for circuit board 44, which "does not have any specific
cooling requirement . . . the internal electrical hookup is greatly simplified by
incorporating this control within a hermetic outer housing 48." Col. 4, ll. 62-65.
