Colorimetric methods have led to the development of visual devices for measurement of benzene concentration. These visual detection tubes have been popular since the 1960s and have provided a simple and rehable method for evaluating ambient aromatic vapor contamination. These products are available from anumber of manufacturers such as Drager (Lubeck, Germany), Gastec (Tokyo, Japan), Kitagawa (Kawasaki, Japan), DuPont (Wilmington, Delaware, USA), and 3M (St. Paul, Minnesota, USA) (85). 

A system for reporting fires and alerting the plant fire brigade and the municipal fire department should be provided. This system should be as simple as possible to minimize the potential for confusion in emergencies. The preferred design is a multiplex system that alarms in the control room or some other 24-hour constantly attended location and activates visual devices, such as strobes or beacons, and audible notification devices, such as a steam whistle, air horn, or tone generator. Complete systems are available from recognized vendors. 

Visual devices are also useful for indicating order. Primary among them are lines. Lines form the skeletons of trees and graphs, both of which are commonly used to display ordered concepts, to indicate asymmetry on a variety of relations, including kind of, part of, reports to, and derived from. Examples include hierarchical displays, as in linguistic trees, evolutionary trees, and organizational charts. Other visual and spatial devices used to display order rest on the metaphor of salience. More salient features have more of the relevant property. Such features include size, color,... 

These correspondences between choice of graphic representation and choice of interpretation appeared despite the fact that few people in the informant population are aware of the bar/line data use, and even fewer of the bar/line message use. The choice of visual devices for discrete, categorical concepts and for ordinal or continuous ones appears to be naturally derived from physical devices that contain or connect.

Endless quantities of the information which are collected in everyday life are presented to the mankind in the visual form, using various presentation devices. Seeing is a believing is the motto of the unidentified flying object (UFO) observers, which could be used for all other areas of the high-level observations. Contemporary research is based on the detection of variations in the electromagnetic spectmm or interactions between fields or particles in the open systems, which are then presented in the visual form. Figure 13.23 presents the time-space scale and the visualization devices which are used to obtain the information.

Tactile sensation is the most widely spread sensory function in the human body, so it is an essential part of the human perception mechanism. Complete or successful realization of the tactile function may place a cornerstone in the fields of robotics, virtual reality, medical engineering and so on. A tactile display is one of the most important communication devices and it conveys intellectual information in the form of skin stimulation. Although the graphical or visual device has been a typical form of the modern information transferring tool, the role of the tactile display has been extended to various applications, such as attaining reality in video games or guaranteeing accuracy in telemanipulation [1—4]. Especially, it has been a critical means for communication for the visually handicapped.

The percentage share of the inserts made austenite steel in the martensite structure is refered to the visual field of the probe in the given location. Every probe after performance is given a characteristics, in which the visual field is given, determined using special devices defining the visual field at different distances from the tested object. 

The ultrasonic tomograph A1230 was developed to visualize in case of one side access the internal reinforced concrete structure at the depth of 1 m. This device uses 36-elements matrix array. 

Traditional appHcations for latices are adhesives, binders for fibers and particulate matter, protective and decorative coatings (qv), dipped goods, foam, paper coatings, backings for carpet and upholstery, modifiers for bitumens and concrete, and thread and textile modifiers. More recent appHcations include biomedical appHcations as protein immobilizers, visual detectors in immunoassays (qv), as release agents, in electronic appHcations as photoresists for circuit boards, in batteries (qv), conductive paint, copy machines, and as key components in molecular electronic devices. 

In addition to viscometers, optical devices such as microscopes and cameras can be used for defining and solving flow problems as weU as characterizing materials (3—5). Optical techniques allow the investigator to determine the physical stmcture of the material and visualize its flow processes.
