摘要： In a channel selecting device which is for use in a station of a multichannel access radio communication system comprising other stations, a control channel, and a predetermined number of speech channels and which includes a channel selector (11, 12, and 14) for selecting one of the speech channels as a selected channel on starting communication with a specific station of the system, a channel detecting arrangement (11,12 and 14) is coupled to the control channel to detect channel codes of busy channels which are rendered busy among the speech channels by at least two of the other stations. The channel detecting arrangement is operable while the first-mentioned station is in an idle state. A memory unit (30) is coupled to the channel detecting arrangement and stores the channel codes of the busy channels. The channel selector is coupled to the memory unit to select the selected channel from idle channels which are other than the busy channels. Preferably, an erasing arrangement (11,12, and 14) erases each of the channel codes from the memory unit upon` lapse of a predetermined time interval after storage of that channel code in the memory unit. The erasing arrangement may erase all channel codes from the memory unit when a manually operable switch (23) is operated after all channel codes are memorized in the memory unit.

摘要： If previously stored transmitters (channel numbers) allocated to certain programme settings in an entertainment electronics appliance are to be reallocated to the usual programme settings, for example because of changed transmitter distribution (channel number) due to a change of location, reprogramming is necessary. This programming process is very time consuming. The aim of the invention is to obtain a simple sequencing process for reallocating previously stored channels to the desired programme setting number. To this end, a microprocessor (5) receives a command, within a time window predetermined by the command, to read previously programmed data concerning two selected programme settings from a main memory (8) into an auxiliary memory (2/3), from this auxiliary memory (2/3) into another auxiliary memory (4), interchanging the channel numbers, and from this auxiliary memory (4) into the main memory again (8), keeping the same programme numbers.

摘要： The invention relates to a television set provided with an alphanumerical display device for displaying on the television screen (6), as an alternative to the received video picture, another complete picture constituted by alphanumerical data which can comprise all the letters in the alphabet, the numbers from 0 to 9 and graphic symbols. The invention also relates to a receiver provided with colour picture display means for displaying, following a control from the user, a calendar data constituted by at least one of the said colour pictures and composed of alphanumerical characters. The invention also relates to a receiver for receiving radioelectric signals which is provided with an alphanumerical character display device in which the tuning of a radioelectric signal takes place by means of a message from the user composed of alphanumerical characters and representative of the station which transmits the said radioelectric signal. The invention relates furthermore to a receiver comprising reproducer means for reproducing on a display screen, or reproducer printing means or vocal reproducer means for the reproduction of alphanumerical data, in which the instruction from the user for the generation of the alphanumerical data coded control signals takes place by means of telecontrol unit. All the said receivers comprise a control unit (1, 2) comprising an alphanumerical keyboard apt to generate atleast as many coded control signals as the characters which can be generated for being reproduced, a control unit (3) for the detection of the control signals generated by the control unit, and circuit means (4) for generating, through reproducer means (5), the alphanumerical data formed by the said selected characters.

摘要： A signal receiver generates a reference signal that sweeps frequencies of desired channel bands, and then feeds the reference signal to an input terminal of receiver unit via a signet-switching circuit that performs switching of the desired-channel signal and the reference signal. The signal receiver then detects the signal strength present in plural frequencies of intermediate frequencies delivered to an output terminal of the reference signal, and after storing detected signal data in a memory, the signal receiver compares the detected signal data to aimed frequency characteristics. Then, the signal receiver determines tuning voltages of respective tuning circuits so that difference arose from the comparison can be minimized. After determining the tuning voltages, these voltages are delivered to respective tuning circuits, and then switching operation between the reference signal and the desired channel signal is executed before the signal receiver eventually receives the switched signal.

摘要： The invention concerns a telemetry transmitter system with a transmitter unit (7-13) and a microprocessor (3). In order to avoid the need to keep large stocks of telemetry transmitters, the telemetry transmitter system of the invention is designed so that the transmitter unit (7-13) has a frequency-control device (7) and an oscillator (9), and the microprocessor (3) is connected to a frequency-input device (1) which generates a control code for the frequency-control device only from certain permitted transmitter frequencies. The code is registered in a non-volatile memory (4) by the microprocessor (3) which, when it is switched on, reads the control code out of the non-volatile memory (4) and feeds it to the frequency-control device (7).

摘要： The apparatus for use in a television receiver of the kind controlled by a micro-computer (10) is intended for the situation in which power failures occur and specifically where instantaneous power failures occur and shortly thereafter the power is recovered, in which it is determined whether or not the time display data stored in a memory of the micro-computer is correct and, if so, such data is continued to be refreshed and is used for the time display, whereby a so-called backup circuit is simplified in construction, and even eliminated in some cases. The main television receiver control data are stored in a nonvolatile memory (24) when a power interruption occurs, but are only used to refresh the random access memory (13) of the micro-computer (10) in those instances where the power outage exists for a period of time long enough to erase the time display data retained in the random access memory (13), a condition that is determined by checking such time display data each time it is necessary to reset the central processing unit (11) of the micro-computer (10) in view of a drop in line voltage.
