A method includes obtaining instructions for a customized function block in a parametric block type. The method also includes developing, at a parametric block engine, the customized function block based on the instructions in the parametric block type. The method further includes executing the customized function block. Executing the customized function block may include executing the customized function block using firmware associated with a controller in a process control system. The parametric block engine may be pre-loaded into the controller before the controller is activated in the process control system.

At the simulation of a visual field of view as it is used on battle trainers, the image (16) of a background and the image (18) of a moveable target is displayed on a TV-monitor in the field of view of the optics of a person to be trained. The images are digitally stored whereat each image point according to its gray value (G.sub.H, G.sub.Z) is digitally coded. Additionally, with respect to individual objects (forest, bush etc.) in the background each image point is provided with a digital encoded range information (E.sub.H). By comparing this range information (E.sub.H) with the range information (E.sub.Z) of the target it is possible to decide with respect to the image area in which the target is present (G.sub.Z >0) whether the target is to display in front of or behind the individual object (FIG. 2).

For the implementation of a regulating and/or control system under use of a microprocessor, the system first is arranged column by column and line by line in a functional diagram. The input values of the system are written in an X-register line by line. Also, parameters are written line by line and column by column into a parameter register. An interpreting computer combines line by line and column by column the input values, respectively, the parameters with the predetermined function with the computer being instructed by a program stored in a configurator. The output values of the interpreting computer per column are written line by line in a Y-register. The contents of the Y-register is transferred back into the X-register if the maximum number of lines of the respective column is run through and the maximum number of columns is not yet reached. On the other hand, the contents of the Y-register is delivered as an output if the maximum number of lines of the respective column is run through and the maximum number of lines is reached.

An anti-backflow valve to prevent back-flow of water within a water supply line comprises a cross-shaped housing arranged symmetrically with respect to a vertical center axis. A diaphragm is clamped between the housing and a cover and acts via a valve stem upon a relief valve. Parallel to the valve stem and located on each side of it are two check valves arranged within bores of the housing. Both check valves as well as the relief valve are arranged in a plane containing an inlet and outlet of the housing to produce a compact and symmetrical configuration which is easily inserted into a water supply line.

In a serial bus system an active representation of the logic states of a bus signal for transmission of both logic states is implemented either on two separate lines for separate transmission of the logic states thereon or on a single line with both logic states being represented by different frequencies.In the method selection of a subscriber connected to the bus, the subscribers wishing to transmit a message indicate this by issuing a collision signal to the bus. The time period during which the collision signal is issued by each subscriber is chosen in such a way that each subscriber of the bus has the possibility to be prepared for the selection. The selection of the subscriber wishing to transmit a message then is done by means of an address comparison on a bit-by-bit basis.

A method for producing sinusoidal waves uses the steps of generating a plurality of clock signals during a 2.pi. period, using the clock signals to control the generation of 2.pi. periodical square wave pulses having preselected length and phase relationships during respective ones of the clock signals and applying the square wave pulses to a low pass filter. The reduction of pulse length as well as the phase relationship of the pulses is evaluated from a system of equations by setting the odd harmonics of corresponding Fourier series to zero or to a predetermined minimum value. A circuit device utilizing this method uses a switching amplifier operated in a binary sequence having a period corresponding to the desired sine wave period and a low pass filter connected to the output of the amplifier. A clock oscillator having a clock frequency higher than the frequency of the desired sine wave controls the amplifier via a sequencer having a counter stepped by the oscillator with the counter outputs being applied to the switching amplifier through a logic circuit.

At the simulation of a visual field of view for training of a battle situation, the image of the background is displayed on a TV-monitor (16) which is arranged in the field of view of the optics of a person to be trained and moveable targets are cut in in the background image. The background image as well as the target image are digitally stored and are displayed on the monitor after conversion into a video signal. In order to simulate a thermal image on the monitor, the gray scale levels of a daylight video picture of the background image point by image point are treated with an evaluation function which may be obtained for instance by comparing the daylight video picture with a true thermal picture. The thermal image representation of the cut-in targets for instance may be generated by a computer (FIG. 2).

A humidity sensor operates with a capacitive sensor element (C.sub.S) which is arranged in one branch of a free-running multivibrator (MV), whereas a reference capacitor (C.sub.ref) is arranged in the other branch of said multivibrator. Both output signals (U1, U2) of said multivibrator (MV) are averaged by means of RC elements (R3, C1; R4, C2) and supplied to a differential amplifier (DV), the output signal (Ua) of which changes the operating voltage (U.sub.B) of the multivibrator (MV), and therefore, linearizes the characteristic of the capacitive sensor element (C.sub.S).

A method of clearing a biaxially directive gun from obstacles lying at a fixed position in relation to the gun position. The method is used in conjunction with guns which are positioned by a gunner operated sight via a selsyn. The normal control signals transmitted from the gunner operated sight to the gun director circuits are interrupted at predetermined azimuth and elevation positions corresponding to an obstacle location, and preset azimuth and elevation signals are interposed to avoid the obstacle. An example of logic circuitry and other apparatus for implementing the method of the invention is disclosed.
