Architectural rigidity is the shortcoming of a process layout to reply to new industry calls for. it truly is an incredible but usually hid factor in excessive tech platforms. In From medical device to business machine, we glance on the phenomenon of architectural tension in embedded structures within the context of a transmission electron microscope approach outfitted via FEI corporation. typically, transmission electron microscopes are operated by hand medical tools, yet additionally they have huge, immense power to be used in business functions. even if, this new marketplace has relatively diverse features. There are robust calls for for low-cost research, exact and distinctive measurements, and ease-of-use. those calls for will be translated into new method features, e.g. reliability, predictability and excessive throughput, in addition to new services, e.g. automation of electron microscopic analyses, automatic focusing and positioning functions.

From medical software to commercial machine takes a practical method of the matter of architectural rigidity. particularly, it describes the results of the Condor undertaking, a joint endeavour via a consortium of commercial and educational companions. during this collaboration an built-in procedure was once necessary to effectively mix a variety of medical effects and express the 1st steps in the direction of a brand new course. procedure modelling and prototyping have been the most important concepts to improve larger realizing and cutting edge options to the issues linked to architectural stress.

From medical tools to business machine is concentrated in most cases at business practitioners, particularly method architects and engineers engaged on excessive tech structures. it could for that reason be learn with no specific wisdom of electron microscope structures or microscopic purposes. The publication kinds a bridge among educational and utilized technological know-how, and excessive tech commercial perform. by means of displaying the methods and recommendations constructed for the electron microscope, it truly is was hoping that process designers will achieve a few insights in how one can care for architectural rigidity in related demanding situations within the excessive tech industry.

The stub’s main task is to simulate a PIA in a state that the Host expects. Therefore it sends the Host fake status messages and image messages (which might be the last image sent before the experiment started). Although command 36 3 Feasibility Prototyping control experiment logic PIA cmd rsp stat img EXPLA stub Host PC Fig. 10 Advanced experiment use case messages are not expected in this situation, commands are all handled by the stub. After the experiment the stub restores the state of the PIA and switches control back to the Host.

Simulator Architecture and Capabilities The first step towards developing the simulator was to provide a model of the functionalities of current TEM components and their relations from the point of view of a control engineer. 12 shows an example of such a model. , scheduling, throughput) High-level Supervisor optics deflector coils rd (t ) objective lens f (t ) mechanics controller rz (t ) holder arm D f (t ) y (r , t ) CCD/ wave formation sensors T (r - rx ,y (t )) rx ,y (t ) aperture selector image formation process - specimen holder motors TEM + optics controller specimen I (r , t ) image processing sensor f (r - rx ,y (t )) da (t ) mechanics Fig.

The second mode is typically used for direct process control. A TEM has to perform three main types of observation functions in these new application areas. An elementary function is determining the size of nanoparticles. While apparently simple, in practice it proves very difficult to achieve both accuracy and precision in a short time using state-of-the-art systems. e. the creation of a three-dimensional representation of nanoscale objects, or aggregated structures. The third function is determining the chemical composition of particles in terms of atoms or molecules.
