Abstract: The object of the invention is a method for changing the frequency band used by a mobile station in a mobile station system. The invention is based on the idea that instead of using a fixed threshold value to change the frequency band, it is replaced with a variable threshold value in connection of a failed attempt to change the frequency band. The variable threshold value is based on the signal levels measured on both frequency bands and used to obtain the new threshold value. A fresh attempt to change the frequency band is made applying the new threshold value.

Abstract: 1282295 Vocoder excitation detection INTERNATIONAL BUSINESS MACHINES CORP 29 Oct 1969 [29 Oct 1968] 52863/69 Heading H4R In a vocoder excitation function generator a sequence of excitation function signals, representing the magnitudes of a predetermined number of successive excitation function periods, is compared with a number of predetermined configurations, representing alternative variations in the excitation function period over the same predetermined number of periods, in order to generate a coded signal representing the predetermined configuration having the best match. The coded signal is transmitted, together with a starting value of pitch period at the commencement of a voiced sound, to enable selection of appropriate values of excitation function at the vocoder synthesizer. As described, Fig. 3, groups of six successive pitch periods are treated and compared with five alternative patterns of variation, a possible set being shown in Fig. 4 where P0 is the final value obtained with the previous configuration. The initial value P0, determined as the final value of the previous configuration, or the initial value of pitch period at the start of a voiced sound is fed from a gate circuit 6 via "and" gate 75 and "or" gate 74 to register 80. The value is then fed to register 82 where it serves as a basic value for the generation, in registers 83 to 87, of the possible values of pitch period in the predetermined configuration. The succeeding six values of pitch period are fed successively into subtraction device 8 to be compared with each successive value of each predetermined configuration and the results for each configuration fed into respective accumulators A1 to A5. After the six values of pitch period have been fed into the subtraction device 8 and the differences from the predetermined configuration stored in accumulators A1 to A5 the detector circuit 69 determines which accumulator contains the smallest value and indicates at its output the number of the predetermined configuration closest to the incoming configuration. This number is transmitted on line 71. A detector circuit is described for determining the minimum accumulator value in which the binary values stored in the accumulators are inspected and progressively shifted towards and out of the highest order bit position until one accumulator contains all zero's, that accumulator containing the lowest value and having its number transmitted as the number of the closest configuration.

Abstract: 1,238,794. Digital measurement of dimension. OSTERREICHISCHE STUDIENGESELLSCHAFT FUR ATOMENERGIE G.m.b.H. 28 Jan., 1969 [2 Feb., 1968], No. 4588/69. Heading G4H. The average height and the shape of a non- plane surface, e.g. the heap of charge in a blast furnace are determined by radiation from radio-active sources 5-9, Figs. 1 and 2 which is received by detectors arranged in vertical columns 1-4 to lie in three horizontal planes below the planes containing the sources 5-9. Rays from each source may be received by two detectors and each detector receives rays from two sources. The rays pass downwardly at an angle acute to the horizontal. The radiation sources are arranged in the cooling boxes of the furnace wall. They may comprise cobalt-60 sources each contained in a lead tube having angled bores to direct the rays towards the detectors. The rays are weakened by passing through the heap of material, according to the amount of material in the ray path. The detectors may be NaJ-scintillation crystals which produce pulses at a frequency depending on the intensity of radiation. They are mounted within the cooling boxes in stainless steel tubes and screened by lead tubes at the receiving end. The outputs of the twelve detectors are applied to counters which store signals representing the number of pulses received. Radiation from a reference source is detected by a detector and the pulses counted by counter. Outputs from this counter give reset and read-out pulses for the other counters. Since all the sources decay at the same rate the system is compensated by increasing the counting time. The outputs of the counters are applied each to a digital-toanalogue converter and the output used to control a graphical recorder, the depth of the charge being determined by an averaging operation. The counters associated with each vertical group of three detectors are also applied to individual digital-to-analogue converters enabled in turn by the reference counter. The results are graphically recorded to show the profile shape of the charge. The radiation source may be provided in a central tube in the heap of charge.
