20090157229 | METHOD AND APPARATUS FOR PLATING SOLUTION ANALYSIS AND CONTROL - A plating system comprises a plating solution and an apparatus for control of the plating solution, the apparatus including a Raman spectrometer for measurement of organic components, a visible light spectrometer for measurement of metallic components, and a pH probe. The plating solution can be sampled continuously or at intervals. Dosing of the plating solution adjusts for components consumed or lost in the plating process. The method of dosing is based on maintaining a desired composition of the plating solution. | 06-18-2009 |
20100121491 | METHOD FOR TRACKING POLLUTION SOURCE IN PROCESS WATER - A method for tracking a pollution source in process water is presented. Firstly, variation curves of drain water drained from different rinsing tanks are respectively obtained, and a water quality concentration of the drain water drained to a buffer tank is detected, so as to output a water quality variation curve. Then, an analytical comparison is performed on each drain water amount variation curve and the water quality variation curve within a same time interval, so as to output an analytical result of each flow of drain water in a range exceeding a predetermined water quality standard. In this manner, the drain water that exceeds the predetermined water quality standard can be tracked in real-time according to the analytical result, thereby quickly improving the process for discharging the drain water. | 05-13-2010 |

20120022693 | MULTI-CHANNEL CHEMICAL TRANSPORT BUS PROVIDING SHORT-DURATION BURST TRANSPORT FOR MICROFLUIDIC AND OTHER APPLICATIONS - A controllable multiple-channel chemical transport bus providing routing and transport of fluids, gasses, aerosols, slurries and the like within a larger system. The system and methods are applicable for use in Lab-on-a-Chip (LoC) technology, and can be useful in the implementation of reconfigurable LoC devices. Routes through the bus are determined by control signals and/or sequences of control signals issued under algorithmic control. Several independent flows may occur simultaneously. Adaptations of Clos, Banyan, and other related multi-stage switching architectures in the flow topology can be supported. The controllable multiple-channel chemical transport bus can be configured to support chemical flow durations short enough that the chemical flow at a first chemical flow port ends at a time before the chemical flow is first received at a second chemical flow port. Sensors may be placed at various locations along bus line segments and may be used in timing of the flows. | 01-26-2012 |
20120173023 | APPARATUS AND METHOD FOR CONTROLLING AUTOTROPH CULTIVATION - A method includes receiving at least one measurement of a dissolved carbon dioxide concentration of a mixture of fluid containing an autotrophic organism. The method also includes determining an adjustment to one or more manipulated variables using the at least one measurement.

20140188282 | INTEGRATED BIO-REACTOR MONITOR AND CONTROL SYSTEM - Systems and methods for automatically controlling conditions of a process are disclosed. In one example, a controller is programmed with a sequence of steps and parameters required to carry out a bioreactor process. The controller receives information related to a condition of the process over a first communication network, determines a control signal based on the received information and the programmed process, and sends the control signal over a second communication network to a benchtop utility tower. In one example, the utility tower can include transmitters for temperature, pH, and dissolved oxygen that send information related to a condition of the process to the controller over the first communication network, and an agitation system, a gas control system, a temperature control system and a pump control system that perform a control action based on the control signal affecting the process condition. The utility tower can include a computer with a human-machine interface that communicates with the controller over a third communication network. | 07-03-2014 |
