A display device to display a representation of a set of states, each one of the states being associated with a corresponding variable. Each of the states displayed is designated as being a most significant state for the corresponding variable. Input representing a probability estimate to be associated with a displayed state is entered and used to generate data for use in an expert system.

Method and apparatus for assisting with construction of data for use in an expert system

A method of locating an assembly point (P) on a first part (), at which assembly point the first part is to be joined to a second part (), the method comprising the steps of: determining an assembly location () in respect of the second part; measuring a portion () of a surface () of the first part, the surface being spaced away from the second part, so as to define the position and orientation of the surface; and, calculating the assembly point on the surface of the first part, where the surface of the first part is intersected by a vector (N) passing between the determined assembly location and the surface of the first part.

Assembly method

A proximity fuze for use in a tube launched projectile carrying a payload, comprising an oscillator for generating a radio frequency signal which has a varying frequency, a single antenna for transmitting the radio frequency signal and for receiving an echo of the radio frequency signal, a first signal processor for generating a range signal corresponding to the time delay between the transmission of the radio frequency signal and the receipt of the echo signal, second signal processor for comparing the range signal with a reference signal and depending on the result of the comparison generating an activation signal for activating the payload, wherein a directional coupler is used for coupling the radio frequency signal from the oscillator to the antenna and to the signal processor and for coupling the echo signal from the antenna to the signal processor, and wherein the second signal processor comprises a threshold detector, a peak detector and a comparator, the threshold detector being for allowing the comparator to utilise the output from the peak detector only once the range signal has reached a predetermined magnitude.
