| Valve positioning systems may include one or more components and a controller. Components may include one or more electric-to-pressure output converters, relays, gas supplies, and/or actuators. A controller may adjust a position of a valve by sending a signal. The valve positioning system may individually monitor components and determine the condition of each component being individually monitored. The valve positioning system may determine if a component will fail prior to failure and/or determine if a problem will occur in a component prior to the problem occurring. | ||||||
| 182 | Valve Status Monitoring | US11570351 | 2005-07-05 | US20080017824A1 | 2008-01-24 | Shane Mason |
| A valve apparatus has a valve (1), an actuator (2) and a leakage sensor (3). A body (4) of the valve has first and second valve chambers (6, 8) connected to respective valve ports (10 & 12, 14 & 16) and joined by an intermediate passage (18). The valve can be set by the actuator to any one of three valve configurations. In an ‘open’ configuration the intermediate passage is open to interconnect the first and second chambers. In a ‘closed’ configuration, the intermediate passage is closed by first and second seals (24, 26) seated at respective locations in the passage to seal respectively between the first and second chambers and a leakage chamber (28) at the portion of the intermediate passage between the two seals. In a ‘cleaning’ configuration one of the seals is unseated to connect a respective one of the first and second chambers to the leakage chamber, while the other seal remains seated. The leakage sensor is connected to the leakage chamber to provide a signal indicative of a leakage flow from the leakage chamber. | ||||||

| A leak detection system is described for detecting a leak through a closed valve disposed between an upstream pipe and a downstream pipe of an industrial process. An insertable plate is coupled to the valve in the pipe in-line with the fluid flow. A sensor couples to the flow and provides a signature output. A leak detector is coupled to the sensor and adapted to detect a leak through the valve based upon the signature output. | ||||||

| 185 | Service panel with utility controller | US09662522 | 2000-09-14 | US06775593B1 | 2004-08-10 | Philip A. Parker; Tom S. Dunn |
| A combination utility controller and service panel having an outer overall enclosure with a lockable door for limiting access thereto to authorized persons. Within the overall enclosure are two sub-regions that are separated from each other by gas-tight paneling. One of these sub-regions (i.e., a service region) contains at least one electrically-operated (e.g., solenoid-operated) valve that is serially connected within service utilities (e.g., water or gas) piping so as to control flow therethrough. The other sub-region (i.e., a utility controller region) contains electrical controls for controlling the valve(s) and communicating with other services such as an auxiliary monitoring system (e.g., a fire alarm system). Digital electronics capability is employed and facilitates provision of numerous features including: emergency shut down by anyone while permitting reset only by authorized personnel; modular construction so as to facilitate initial installation of the overall enclosure including the aforementioned service region followed subsequently (if desired) by addition of the utility controller module. Paneling and gasketing provide separate integrity of the subregions so that they may be included within the same overall enclosure while providing for safety from leakage | ||||||

| An optical code division multiple access transmission and reception system is presented. The transmission system comprises an optical comb generator for producing multiple discrete optical signal components comprising a plurality of equally spaced wavelength components. A serial-to-parallel converter is connected with the optical comb generator for receiving receiving the serial signal components and for converting a selected group of the serial signal components into parallel signal components. An optical free-space code mask is connected with the serial-to-parallel converter for receiving the parallel signal components and for selecting two separate groups of optical signal components to generate two subsets of signal components, each for representing an associated binary data value from a data stream. The transmission system may comprise further components to enable transmission via fiber optic cable or into free-space via an antenna. The reception system operates opposite the transmission system to de-code a coded signal, obtaining the original data. | ||||||

| A method that simplifies the exchange of data to facilitate delivery of data that relates to operation of a valve assembly to a Web-based user interface over a network. In one embodiment, the method configures an apparatus to receive data about the valve assembly in a first format and to generate an output in a second format, e.g., JavaScript Object Notation (JSON) format. The method may also configure the device with an architecture with multiple layers, wherein the architecture can exchange data in the JSON format between a first layer and a second layer. This architecture is configured to be lightweight as compared to the SOAP/HTTP architecture found in conventional techniques, typically deploying a Representational State Transfer (REST) structure that permits use of JavaScript Object Notation (JSON) format to communicate among the architecture layers and with the web-based user interface. | ||||||
