Patent number: 6976503Abstract: A diagnostic system, for a valve (2), having a sensor (12) that senses structure-borne noise and having a device (14) for evaluating a measurement signal (13) of the structure-borne noise. During a calibration process, a first progression of the measurement signal is sensed for the closed position of the valve (2) and a first value (w1) of a characteristic is determined. To simulate leakage noise, the valve (2) is nearly closed during operation, a second progression of the measurement signal is sensed and a second value (w2) is determined. If the deviation of the second value from the first value is sufficiently large, a diagnosis is possible. A third progression of the measurement signal is sensed for the closed position of the valve as in an installed condition, and a third value (w3) is determined. If the deviation of the third value (w3) from the first value (w1) is too great, and if a diagnosis has been identified as being possible, then the system deduces that the valve leaks.Type: GrantFiled: October 26, 2004Date of Patent: December 20, 2005Assignee: Siemens AktiengesellschaftInventors: Wolfgang Ens, Alf Puettmer

Patent number: 6860288Abstract: A system for monitoring and controlling one or more utility systems includes a utility system main supply line for supplying a utility to at least one of a structure, an area and a building and a controlled shut-off device on the utility system main supply line. The controlled shut-off device is bias toward an open position and is movable toward a closed position upon receipt of an actuation signal wherein the utility is prevented from passing by the controlled shut-off device. A main utility sensor is on the utility system main supply line and a motion sensor that detects occupancy is in the building. A processor communicates with the controlled shut-off device, the main utility sensor and the motion sensor. The processor sends the actuation signal to the controlled shut-off device to move the controlled shut-off device toward the closed position when input from the main utility sensor and the motion sensor indicates occurrence of an abnormal event.Type: GrantFiled: February 23, 2004Date of Patent: March 1, 2005Inventor: Kenneth J.

Publication number: 20040123907Abstract: A gas delivery system for providing a gas to manufacturing equipment includes a gas supply unit for providing the gas to the manufacturing equipment including devices to regulate the supply of gas from the gas supply unit to the manufacturing equipment. The system includes a main control unit for regulating the supply of the gas to the manufacturing equipment. The gas delivery system includes a supplemental control unit which receives an emergency shutdown signal from the main control unit for closing off the supply of gas in response to a malfunction of the main control unit and generates a signal for maintaining a gas flow to operate the manufacturing equipment until the cause of the malfunction has been determined. With the system, an unnecessary emergency shutdown of gas supply to semiconductor manufacturing equipment in response to a malfunction of a main controller can be prevented.Type: ApplicationFiled: September 18, 2003Publication date: July 1, 2004Applicant: Samsung Electronics Co., Ltd.Inventors: Yu-Kweon Kim, Seung-Ki Chae, Jai-Kang Jeon, Young-Seok Roh, Yong-Wook Lee

Patent number: 6701951Abstract: A device and method to implement the device, to automatically adjust a single valve or a plurality of valves including turning the valve(s) on and off. The device includes a motor drive assembly, a mounting method, and a control method. Each component is discrete. The three components can be combined easily. The motor drive and control components can be mounted and connected to a valve that is currently connected to pipes. Thus one application of this invention is to provide a method to convert a manual valve to an automatic valve. The control method can operate as a means to turn the valve on and off using a manually operated switch or can be automatically controlled in response to an external stimulus. The invention has many applications including protecting real property from loss due to water damage, and against vandalism in cases where valves can be controlled by unauthorized people.Type: GrantFiled: September 25, 2000Date of Patent: March 9, 2004Inventor: Don Lovis Drinkwater

Publication number: 20040035469Abstract: A normally closed electromagnetic valve is closed again after temporarily being opened during an abnormality check of the valve. When the valve is opened, electricity is supplied so that a plunger is moved by a coil but a back face of the plunger does not abut against a receiving face of a fixed portion. Because the plunger does not strike the fixed portion, no impact noise is generated. Also, when the valve is closed, the electricity is not instantly dropped to zero, but is gradually reduced. As a result, impact noise when the valve strikes the valve seat is able to be reduced.Type: ApplicationFiled: August 11, 2003Publication date: February 26, 2004Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Masakuni Suzuki
