Abstract: Disclosed systems manage the modification of objects such as automated reports. Access to modified versions of an automated report is controlled during the modification life cycle. A developer checks out a copy of an automated report and stores minor versions of the automated report during modification. A major version of the automated report is backed up and a copy of the modified automated report is transported to a quality control agent, which may be given substantially exclusive access to the modified automated report. Upon the quality control agent indicating the automated report is a quality-compliant automated report, the quality-compliant automated report is transported to a release manager. The release manager is for determining whether the quality-compliant automated report is a releasable automated report.

Abstract: An valve actuator in a hydronic heating and cooling system includes a motor for changing the position of a valve, a switch for switching power to the motor, and a sensor for detecting the arrival of the valve at a desired position and for stopping the motor without using a mechanical stop. The motor's power source includes a capacitive power source which can be used to drive the motor under low-power conditions. A worm gear is used in the drive train, and combined with a clutch assembly to permit the valve to be operated manually.
