Abstract: PCT No. PCT/EP94/03171 Sec. 371 Date Mar. 11, 1996 Sec. 102(e) Date Mar. 11, 1996 PCT Filed Sep. 23, 1994 PCT Pub. No. WO95/09513 PCT Pub. Date Apr. 6, 1995Known methods for determining base station locations are based on human choice of that location which has the lowest degree of coverage (i.e. locally too little or no field strength present of neighboring base stations). The method according to the invention involves automated determination of base station locations by calculating, for each location, a number which is a function of a parameter associated with that location (telephone traffic, field strength, motor traffic) and of parameters belonging to adjoining locations, and by assigning a base station to the location having the most extreme number. Then the parameter associated with that location, and the parameters associated with adjoining locations are each adjusted on the basis of an adjustment function associated with the base station, and new numbers are calculated which are a function of the new, adjusted parameters, etc.

Title: Detecting voltage induced in coils by changing current
IPC: H04N3/16
Filed: 1970-01-09
Abstract: 1,274,431. Cathode-ray tube circuits. INTERNATIONAL BUSINESS MACHINES CORP. 9 Jan., 1970 [14 Jan., 1969], No. 1064/70. Heading H4T. Apparatus for detecting when the rate of movement of a CRT spot falls below a safety level utilizes the voltage across the deflection coils and compensates for the resistance of the coils by the use of a series resistor in the deflection circuit, a differential amplifier receiving at one input the potential across the resistor (suitably sealed) and at the other the total voltage. When the scaling factor is adjusted so that a sawtooth input to the coils causes a squarewave output, then the output signal will at all times indicate the rate-of-change of flux through the coils and hence the spot speed in the corresponding direction. In the embodiment described, four signals representing X and Y movements in both positive and negative directions are used in two functional ways. Firstly, if none of the four exceeds a reference representminimum spot speed a bi-stable circuit is set to blank the beam to prevent screen damage; secondly each signal is checked against the corresponding logic signal initiating the scan, and any discrepancy arranged to set a "disable" latch to indicate malfunction of the scan circuitry.

Title: Improvements in and relating to magnetic-field responsive devices
IPC: G01R33/02
Filed: 1944-01-19
Abstract: 624,406. Magnetic tests. SPERRY GYROSCOPE CO., Inc. Jan. 19, 1944, No. 1083. Convention date, Jan. 19, 1943. [Class 37] [Also in Group XXXVIII] A flux valve comprises a core formed of magnetically permeable legs arranged in th form of a triangle or other polygon, an exciting winding adapted to produce an alternating flux circulating round the core from one leg to the other in succession, and a plurality of secondary windings providing output voltages between a plurality of output terminals, the circuits between the output terminals comprising pairs of windings, the two windings of a pair being arranged on adjacent legs of the core and connected in series in such a manner that, in the absence of an external magnetic field, the voltages induced therein by the alternating flux are substantially equal and opposite. As shown in Figs. 1 and 2, the core is arranged in the form of a closed equilateral triangular frame. The legs 1, 2, 3 are of highly permeable magnetic material in contact with one another at the vertexes of the triangle, or they may be integral. As shown, each leg comprises two strips 4, 5 wound with an exciting coil 6 over which are two secondary coils A, B, C. The exciting coils are connected in series or in parallel and to a source of alternating or pulsating current. The secondary coils are connected as shown in Fig. 4. The pairs of coils A, B, C comprise separate coils 8 ... 13, one coil of each pair being connected to a coil of another pair on an adjacent leg of the core and then Y-connected between a common point and three output terminals. The coils of each of the connected pairs, e.g. 8, 10, are connected in voltage opposition as regards the exciting flux so that the induced voltages cancel out and the fundamental frequency of the exciting current is eliminated. An external field 14 such as that of the earth passes through the legs 1, 2 so as to add to the exciting flux in one leg and oppose it in the other.. An additive voltage is then generated in the coils 8, 10 and an output signal results. The plates 4, 5 forming the core legs are supported in a non- magnetic casing 15 and are positioned by pins 16. Collector horns 17 are clamped between a ring 18 and the rim of the casing 15. The collector horns may be omitted and the legs 1, 2, 3 may be slightly spaced apart at the vertexes. The output terminals may be connected to the Y-connected polyphase windings of a selsyn receiver, the single-phase output from which may be used for control purposes, e.g. to control a directional gyroscope to produce a gyromagnetic compass.
