An apparatus and method for measurement, analysis, and optimization of content delivery over a communications network is presented. In one embodiment, the apparatus detects data packets en route over a communications network. The detected data packets are read by the apparatus, combined into application messages, and further combined into user centric events. The events are analyzed to identify metrics and statistics relating to the delivery of content over a communications network and the experience of the end user. The metrics and statistics are saved in a data storage area. When the metrics exceed a configurable threshold, the apparatus provides real-time notification of content delivery problems or end user experience problems. Alternatively, the system can take action to proactively prevent anticipated content delivery problems or end user experience problems.

An ultrasonic monitor to measure the level of a fluid (e.g., oil or water) within a storage tank. The ultrasonic monitor is surrounded by a gas-tight, explosion-proof casing that is coupled to the top of the tank so that the acoustic axis of a (e.g., 59 KHz) ultrasonic transducer is directed downwardly towards the surface of the fluid. The ultrasonic transducer is encased within a protective (e.g., Delrin) housing so as to resist the hostile (e.g., acidic, gaseous vapors and extreme temperature) conditions within the tank. A main CPU is interconnected between the ultrasonic transducer and an RF transceiver having an antenna from which fluid level data calculated by the main CPU can be transmitted over a wireless communication path. A reference rod having at least one acoustic reflector located at a known distance therealong extends downwardly from the housing of the ultrasonic transducer towards the surface of the fluid. The main CPU is responsive to the time of flight between incident signals generated by the acoustic transducer and return and echo signals reflected off the surface of the fluid and the acoustic reflector for calculating the corresponding distance between the fluid and the transducer. The main CPU is adapted to adjust the time of flight to compensate for errors introduced by the environment (e.g, gas vapors, pressure, etc.) of the tank depending upon the echo signal that is reflected to the acoustic transducer by the reflector of the reference rod.

A method and apparatus that uses the Internet protocol, TCP / IP, for a home control network. The invention also provides embedded servers, email clients at the electrical boxes. The invention integrates the Internet to the electrical outlet, switch, or appliance boxes using a low cost embedded web server.

The present invention provides automated systems and methods for monitoring column performance in process chromatography, and applications thereof. In an embodiment, column performance is monitored by generating a plurality of process values such as, for example, conductivity values or pH values with a detector during a chromatography step transition between a first mobile phase liquid and a second mobile phase liquid. The process values are transformed to form transformed process values in which noise present in the process values is suppressed. Column performance parameters are calculated based on the transformed process values and displayed during movement of the second mobile phase liquid through the chromatography column. The displayed performance parameters enable an operator to make a determination, for example, regarding the quality of the chromatography column packing and whether to continue the chromatography process or stop the chromatography process until the chromatography column can be repacked or replaced.

A hybrid power conversion system includes an inverter, a switching controller, and an efficiency measurer. The inverter is connected in series to a first converter and a second converter, and the first and second converters are respectively connected to first and second direct current power supplies. The switching controller controls switching frequencies of one or more switches in the first and second converters and the inverter. The efficiency measurer measures efficiency based on the switching frequencies. The switching controller determines the switching frequencies of the one or more switches as frequencies at which the system has a predetermined efficiency based on the efficiency measured by the efficiency measurer.

The invention relates to a method for extracting dioscorea zingiberensis diosgenin in traditional Chinese medicine peltate yam, a preparation agent, and the application of the dioscorea zingiberensis diosgenin in preparing drugs in prevention and treatment of cardiovascular diseases. The dioscorea zingiberensis diosgenin extraction method of the invention adopts enzyme to remove coarse impurities, and then uses weak-polar macroporous resin to extract the dioscorea zingiberensis diosgenin. The method of the invention can significantly improve the purity and extraction rate of dioscorea zingiberensis diosgenin to reduce the production cost. The dioscorea zingiberensis diosgenin of the invention can also prepare coated tablets, syrup, oral solution, drops or capsules; compared with the priorart, the dioscorea zingiberensis diosgenin prepared through the method of the invention has better efficacy and is conducive to the transport and storage. Clinical trials prove that the dioscorea zingiberensis diosgenin extracted in the invention has a significant effect on coronary heart disease, hyperlipidemia and other cardiovascular diseases.
