STANDARD DESIGN INTERFACES

Design and Manufacturing Standard Interconnect Standards for Interfacing Performance Test... 

To start architectural synthesis, an initial data flow analysis is required. It is also this process which resolves the very different nature of current designer interface languages (Vhdl, HardwareC, Silage,. ..). By standardization on the result of this analysis, the input alternatives become available for all the synthesis projects. 

The System 80+ standard Design incorporates the second approach for assuring the reliability and adequate level of safety for the Class IE power sources and safety-related systems by the selective connection of non-safety-related equipment and strict control of the interface between the non-safety-related equipment and Class IE power system. 

The conceptual design of an offsite power system and station switchyard for the System 80+ Standard Design is given in CESSAR-DC Section 8.2. The interface requirements will ensure that the switchyard provides redundant offsite power feed capability to the nuclear unit, consisting of two immediately available preferred power circuits each capable of supplying the necessary safety loads and other equipment. 

Because of the importance of the interface between HP and LP safety-related systems, all pressure containing components used in the System 80+ Standard Design identified as Safety Class l,... 

In summary, the design, manufacture, pre-operational testing, and in-service testing of the boundary valves used in the interface between safety-related HP and LP systems is controlled in accordance with the ASME Code and, thus, satisfies the intent of SRP Section 3.9.6, Revision 2. Therefore, this issue is resolved for the System 80+ Standard Design. 

Standards and interface Details of standards based on which the philosophy document has been developed must be spelled out very clearly. It shall also state at which points compliances are necessary at various stages (discussed in subsequent clauses) such as specification stage, design stage, installation stage, etc. 

Design, including subsequent changes or safety improvements, shall be carried out in accordance with established procedures that call on appropriate engineering codes and standards, and shall incorporate apphcable requirements and design bases. Design interfaces shall be identified and controlled. 

Universal Serial Bus emerged as a result of the difficulties associated with the cost, configuration, and attachment of peripheral devices in the personal computer environment and solves several technical issues associated with old-style peripherals. The USB is an industry standard serial interface between a computer and the peripherals. A result of USB s versatility and ease of use is an interface that is more comphcated than the interface it replaces for developers who design USB peripherals. The original USB specification, version 1.0, was released in January 1996 and version 1.1 was released in 1998. USB version 2.0 was introduced in 2000. USB On-The-Go (OTG) is a new supplement to the USB 2.0 specification. With the introduction of USB On-The-Go, a USB peripheral will have an additional capability to connect to other USB devices directly. 

In our design, we use RS232 standard to interface PC with machine to control and acquire data. This contributes several problems when applied in hospitals. Therefore, we are developing alternative ways by using latest communication standards such as Wifi or Bluetooth, which helps our devices free from bundle of wires. 

A design criterion for a modular system is to have standard flanging to allow the joining of modules from different manufacturers. This type of interfacing is sometimes referred to as SMIF (standard mechanical interfacing). Standards for such interfacing are being developed by the SEMI Modular Equipment Standards Committee. 

Another important feature of a LIMS DBMS is the abiUty to perform ad hoc database queries. It is impossible to predict all the forms in which LIMS users will want to display their data while the LIMS is being designed. As a result, it is desirable to select a LIMS which allows users to define their own reports. Most commercial DBMS have a standard query language (SQL) interface. SQL is a simple database query tool which is based on... 

The standard requires that organizational interfaces between different groups which input to the design process be identified and the necessary information documented.
