Abstract: 1,233,825. Computers. BENDIX CORP. 24 June, 1969 [1 July, 1968], No. 31860/69. Heading G4A. A digital computer comprises means for storing intercept and slope constants corresponding to approximate linear segments of a non-linear function, and calculating means for deriving the function value for a particular value of its argument from the argument value and the constants of a pertinent segment, the latter being selected in accordance with the argument value. In an aircraft, atmospheric conditions (e.g. indicated static pressure, total pressure, total temperature and indicated angle of attack) are sensed, converted to digital form and stored in external registers from which they can be selected and supplied to the computer to calculate other quantities (e.g. altitude, rate of climb, true airspeed, indicated airspeed, free air temperature, air density and angle of attack). Let where x is sensed static pressure and y is altitude, for example. A programmer unit selects values of m and b from a permanent store (diode matrix) in accordance with x and loads them into first and second shift registers respectively, the value of x being supplied via a third to a fourth shift register. A serial full adder/subtractor produces mx in the third register (overflowing into the fourth) by repeated addition of m, with shift, under control of successive digits of x, then produces mx + b in the third register by addition, the third register contents being displayed. The adder/subtractor may subtract one external register from another, via direct connections from the registers, the result going into the third register.

In a magnetic core matrix the bit wires are arranged in a plurality of groups with at least two groups 11 to 11g and 12 to 12g being disposed on one ground plane 10 with the bit wires of the two groups interleaved. Bit current drivers 16, 17 and selection switches 20, 22 are connected to the ends of the bit wires of the bit groups 12 to 12g and 11 to 11g respectively. In operation the bit switches 20, 22 are actuated to select only one bit wire from each group and connect it to ground, the two wires selected being adjacent. Since the half select current from the bit drivers 16, 17 flows in opposite directions through the adjacent bit wires can cellation of induced ground current is achieved, Fig. 2 (not shown) so as to avoid changes in characteristics of half select currents through bit wires which are not centred on ground plane 10.
