Abstract: 816,176. Measuring average speed. GOODHEAD, R. A. Aug. 28, 19M [Aug. 29, 1956], No. 26400/56. Class 40 (1). A device for calculating the average speed of, a vehicle from a given datum point comprises a Wheatstone bridge having four resistance arms, two of these being automatically and remotely varied in proportion to the distance and time elapsed from the datum point, means for continuously balancing the bridge and an indicator coupled to the balancing means. In Fig. 1, the arms D and T are adjusted in steps by impulses obtained from the speedometer of the vehicle and from a clock or electronic counter respectively. The alternating output voltage from the bridge is amplified in V3 and applied to the grids of two thyratrons V1 and V2 whose anodes are fed with A.C. synchronized with the bridge supply. If the unbalance, voltage is large enough one or other of the relays L1, L2 is energized (depending on the phase sense of the unbalanced voltage) and changes the contacts YZ to drive the motor M and rebalance the bridge at S. The modification of Fig. 2 is designed to calculate the time lead or lag of the vehicle over a predetermined average speed. Here the resistor S is preset for a given speed, the small portion 28 of which can be inserted manually to change the preset value by ¢ m.p.h. steps, and rebalancing is carried out on a portion of the arm T. In both circuits each of the arms D and T comprises in series one continuously variable resistor, one 16-step variable resistor changed' one step per revolution of the first and a further 16-step resistor changed one'step per revolution of the previous resistor. The display unit of the instrument has a pointer actuated by the rebalancing motor (either directly or via a selsyn or similar link) and four alternative scales, two for m.p.h. (changed by switching'in different resistors for S in Fig. 1) and two for minutes lead or lag (changed .by switching in different values for 30 in Fig. 2). The usual on/off switches are provided together with a control for returning the speed and time counters to zero before commencing a measurement, and also a switch 29 for inserting the fine resistor 28.

Abstract: 1474812 Semiconductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 June 1974 [18 June 1973] 26416/74 Heading H1K A Hall-effect semiconductor device comprises a layer-shaped body 23A having an array of electrodes 1-8 which are functionally divided into groups, each group comprising an anode and a cathode for passing a main current and one Hall signal contact, all the anodes and all the cathodes respectively being connected together. The groups are paired to form at least two sub-arrays so that the main current directions are parallel in each pair and are different for different sub-arrays. The Hallsignal contacts in a sub-array are of the same polarity and opposite to those in the other subarray, like polarity Hall-signal contacts being connected together and to a common conductor. It is stated that in operation, such an arrangement reduces the offset Hall signal in the absence of a magnetic field component perpendicular to the Hall plate which depends on the direction of current flow. In the embodiments described, in all groups of electrodes which include Hall-signal contacts of like polarity, the main current directions satisfy the condition that the sum of the cosines of twice the angle between each main current direction and any reference axis in the surface substantially vanishes. As shown, the body 23A is square with connections to the electrode array which in operation define contacts 2, 4, 6, 8 as Hall-signal contacts and contacts 1, 5 and 3, 7 as main current anodes and cathodes. The array functions as two sub-arrays with paired groups: (1, 2, 3 and 5, 6, 7) and (3, 4, 5 and 7, 8, 1). The body 23A may be of Si, In As, In Sb or other III-V compounds. The plate 23A may be notched between adjacent contacts (Fig. 5, not shown) to reduce power consumption. In another arrangement, the current paths are separated by a central square of insulation (Fig. 7, not shown) and further insulation may divide the body into separate parts electrically connected externally. In a further embodiment, the Hall body is hexagonal with Hall-signal contacts at apices and main current contacts at side centres (Fig. 6, not shown).
