Patent DE-3821004-A1 (DE)
Inventor: HAKE MARTIN
IPC: H01H25/06
Filed: 1988-06-22
Abstract: Application method for a rotating continuous transmitter for digital pulses in a device of entertainment electronics. As a rule, such pulse transmitters (encoders) are utilised several times, that is to say functions are preselected for which the pulse sequences emitted by the transmitter have an adjusting function. These functions have hitherto been called up and selected by means of keys. It was the object of the invention to simplify the operation by rendering such keys unnecessary. The application method according to the invention provides a rotating transmitter which is coupled mechanically with a switch which is operated at the rotating transmitter operating button. Furthermore, the switching signals generated in accordance with the switch function are used, in accordance with the method, for calling up the rotating transmitter and in agreed sequence after completed rotation, for selecting functions for the subsequent inputting of the function by rotation. The pulse sequence emitted during this process is used as adjusting command for a function, for example volume, balance, tone or others. Via a microcomputer, which exists in any case, for example in devices of entertainment electronics, the switching signals and adjusting commands of the functions are processed and the selection, acknowledgment and leaving of the selection function and, if necessary the storage are effected.
