20120222851 | HVAC SYSTEM DAMPER - A damper for determining and regulating amount of airflow admitted into a heating, ventilation, and air conditioning (HVAC) duct of a building from the ambient includes a variable position gate. The gate is configured to generate a continuous access opening into the duct from the ambient. The damper also includes a mechanism configured to select a position for the gate between and inclusive of fully opened and fully closed and a first sensor configured to sense a velocity of the airflow admitted into the duct. The selected position of the gate determines an area of the continuous access opening and regulates the amount of airflow admitted into the duct. Additionally, when the continuous access opening is not fully closed, the airflow admitted into the duct by the gate is substantially uniform. An HVAC system employing the damper and a method for controlling a temperature inside the building are also disclosed. | 09-06-2012 |
20120284077 | AUTOMATED WORK ORDER GENERATION FOR MAINTENANCE - A method for generating an electronic work order for plant maintenance includes detecting a fault of a machine in the plant, and communicating fault information to a system. The system has a server and a database for recording downtime of the machine. The method further includes generating the work order via the server in response to the fault, including recording, within in the work order, a plurality of values from the fault information. The work order is transmitted from the server to a computing device, and a confirmation signal is recorded by the computing device indicating completion of the repair. The method includes transmitting a completed work order from the computing device to the server and recording the completed work order in the database. A system is also disclosed for generating an electronic work order for maintenance in a plant. The system includes the database and server noted above. | 11-08-2012 |
