The electric meter is a direct tool by which power enterprise charges for electricity Tariff. This paper describes software and hardware designs of MSP430F149 SCM as the core control processor and smart remote transmission three-phase electric meter with the use of power collection special chip CS5460A to complete power measurement. This instrument integrates data monitoring and measurement of the power with LCD. And it can realize the functions of data remote transmission through communication connection between ENC28J60 chip and main controller and easily of real-time monitoring, data collection, system monitoring. This electric meter has some advantages such as powerful function, low cost, strong disturb-resistant ability, etc. and can meet the management requirement of the electricity energy intelligence, which is one of the main development trend in the future. This smart power data collection system will get a good application in the power industry informatization process .

Correlation System

A free text data collection system has been developed at the University of Illinois utilizing single word, syntax free dictionary lookup to process data for retrieval. The source document for the system is the Surgical Pathology Request and Report form. To date 12,653 documents have been entered into the system.The free text data was used to create an IRS (Information Retrieval System) database. A program to interrogate this database has been developed to numerically coded operative procedures. A total of 16,519 procedures records were generated. One and nine tenths percent of the procedures could not be fitted into any procedures category; 6.1% could not be specifically coded, while 92% were coded into specific categories. A system of PL/1 programs has been developed to facilitate manual editing of these records, which can be performed in a reasonable length of time (1 week). This manual check reveals that these 92% were coded with precision = 0.931 and recall = 0.924. Correction of the readily correctable errors could improve these figures to precision = 0.977 and recall = 0.987. Syntax errors were relatively unimportant in the overall coding process, but did introduce significant error in some categories, such as when right-left-bilateral distinction was attempted.The coded file that has been constructed will be used as an input file to a gynecological disease/PAP smear correlation system. The outputs of this system will include retrospective information on the natural history of selected diseases and a patient log providing information to the clinician on patient follow-up.Thus a free text data collection system can be utilized to produce numerically coded files of reasonable accuracy. Further, these files can be used as a source of useful information both for the clinician and for the medical researcher.
