Also provided is a sound-generating finger puppet wherein such puppet can be supported and primarily activated with a single finger. Also provided is a method for producing electronic sound generation in a puppet supportable on a single finger.

Abstract: A remote control toy includes a remote housing and a main housing. The remote housing has a transmitter and a signal generator associated with the transmitter. A plurality of function switches govern the signal generator. The transmitter outputs a signal which is encoded by the signal generator to reflect which switch or switches is activated on the remote housing. The main module includes a receiver to receive the signal from the transmitter. The receiver removes the encoded signal and outputs it to a decoder. Depending upon the signal received, the decoder outputs to one or more of its output ports which are connected to appropriate output devices located on the main module. One of these includes a tape drive which carries a tape therein, and which is capable of recording a sequence of control functions transmitted by the remote module to the main module.

Abstract: In a carrier relay system in which protective relay apparatus are disposed in terminal stations respectively and interchange information between the terminal stations via a signal transmission line for detecting a trouble occurred in power transmission lines on the basis of the exchanged information, specific information K is inserted in a predetermined position of a signal transmitted from the first terminal station to the second terminal station, and the specific information K is inserted intact in another predetermined position of a signal returned from the terminal station to the terminal station. In the terminal station, the specific information K inserted in the signal transmitted therefrom is compared with the specific information K inserted in the signal returned from the terminal station for deciding the presence or absence of a trouble occurred in the power transmission lines.
