    摘要： A CATV system includes a security system incorporated therein through which a subscriber can automatically or manually transmit various warning or emergency signals to the CATV base station. Apparatus at the base operates to determine the type of warning signal received, and transmits a corresponding confirmation signal to the particular home unit. An indicator on the unit gives a visual indication of the receipt of the corresponding confirmation signal.

    摘要： A television scrambling system of the GSS type includes a false key signal to defeat pirate decoders. The false key is placed approximately one half a horizontal line period following the last horizontal sync pulse preceding the vertical blanking interval of the television signal. If the pirate decoder is set to attenuate the video portion of the picture signal in response to receipt of a standard GSS scrambled signal, the pirate decoders will attenuate only the sync portion of the picture signal in response to a signal scrambled with the false key.

    摘要： A sentence forming apparatus forms a plurality of semantically equivalent sentences simultaneously in a plurality of languages by a conversational system. The apparatus includes a semantic dictionary memory which stores a plurality of indexes in a first language, a plurality of words in the first language semantically in coordination respectively with the indexes and grammatical information relating to the respective words, and first language syntax dictionary memory and second language syntax dictionary memory which store information concerning grammatical syntax and word in the corresponding language. A selection menu is formed based on the contents of the semantic dictionary. The apparatus further includes first language sentence assembler and second language sentence assembler which assemble, respectively, the first language sentence and the second language sentence utilizing the information concerning the grammatical syntax and word in the respective languages, in accordance with the selection menu.
