The advent of the microprocessor has made it possible to provide a variety of intelligent instruments for the analytical laboratory. This trend eventually suggested the introduction of the distributed function multiprocessor concept, one of the recent system approaches in computer technology, to accommodate the growing intricacy of laboratory automation systems. To demonstrate an example of unconventional design schemes for intelligent instruments, a distributed function multiprocessor network is implemented in a small spectrophotometer. The total function is divided into basic spectrophotometric measurement, data processing, and data display, and each of them is allocated to an individual microprocessor integrated module which can communicate with others through the IEEE-488 standard interface bus. The notable feature of the system is simplicity of expansion by combining the independent functional modules along the standard interface bus. The details of the system structure and operational procedures are presented together with typical performance data.

In most laboratory LAS (Laboratory Automation System) system recently have been used. though, not all of them used theautomation system and LIS.the LAS is used for the diagnosis of diseases, because it can decrease the error factors as weel as thelaboratoric examination. Regarding to decreasing problems, the expenses of patients who staying in the hospitals could be reduced aswell as their time to stay. the purpose of this article is to know comprehensively LAS and its services in the future in the hospitals' clinicallaboratory. Because before LAS was used the diagnosis time of diseases take a long time as compared to LAS.

System Controller

A distributed microcomputer network system which consists of integral microprocessors in intelligent instruments has been developed for automating the spectroscopy laboratory. In this system, the master-slave arrangement of microcomputers is adopted to compose the system controller and three microcomputer-based spectrophotometers (an UV/visible spectrophotometer, an IR spectrophotometer, and a fluorescence spectrophotometer). The IEEE-488 standard interface bus is employed for the hardware compatibility of the communication between the system controller and spectrophotometer subsystems. The Tiny BASIC language is modified as a standard language in the system for real time execution along the communication through the IEEE-488 interface bus. The operation includes two modes: the local mode and the remote mode. In the local mode, the spectrophotometer is manually controlled independently from the system controller. In the remote mode, the modified Tiny BASIC program controls individual spectrophotometers. The program is written by the user at the system controller and is loaded down to the microcomputer of a spectrophotometer subsystem. This program is executed via the individual modified Tiny BASIC interpreter implemented in the subsystem. The system structure, design of the modified Tiny BASIC, and operating procedures are presented together with typical performance data.

This article outlines a 10-step process for business leaders in the pharmaceutical, biotech, health sciences, and clinical fields, who hire information technology (IT) applications consultants to design, develop, implement, and integrate custom laboratory automation systems. The goal of this model is to identify steps to dramatically improve the effectiveness of the consultant and to reduce implementation risk factors. The probability of project success can be increased significantly when the basics of IT systems development is understood by those internal to the organization and management guides the consultant to the finish line using a defined project control process.

The work is devoted to the reliability of non-recoverable two-channel automation systems and computer equipment. As alternative options, a system with block duplication (SBD) and a system with a quasi-bridge structure (QBS) are considered. SBD in general is a two-channel system consisting of a series connection of duplicated nodes of different reliability. In case of failure of one of the functional subunits (FSU) of the duplicated node using the control and reconfiguration (SCR) scheme, it is masked, withdrawn from the computational process, and reconfigured the system structure in the “Non Stop” operating mode. A QBS system also represents a two-channel structure, but consisting of a serial connection of duplicated nodes of equal reliability, while the technical element intensity (redundancy level) and the functionality of this system are identical to SPD. The QBS system is also a fail-safe system that provides the “Non Stop” mode of operation. The probabilistic-physical calculation method (WF-method) is used as a tool for studying the reliability of systems, which is based on the diffusion distribution of mean-time-to-failure (DN-distribution), specially formalized for assessing the reliability of electronic, electrical and electromechanical elements and systems. While maintaining the redundancy level of the considered two-channel redundant systems, decomposing the channels into equally reliable duplicated nodes leads to the R-effect – an increase in the likelihood of system uptime with an increase in the number of nodes. The presence of the R-effect was established by other methods of calculation and by statistical modeling for both non-restored and restored systems.
