A speaking fire alarm system for not only giving an alarm in voice on an occurrence of a fire but also providing some information necessary for coping with the situations. The system includes a temperature sensor for sensing a surrounding temperature and providing a voltage responsive to the temperature sensed, comparator means for comparing the voltage supplied from the temperature sensor with a reference voltage and thereby providing a logic signal in accordance with its comparison, a central processing unit for receiving the logic signal from the buffer, thereby deciding the occurrence of the fire and providing both a fire alarm signal and message data according to an emergent situation, a voice synthesizer for providing address signals in accordance with the message data supplied from the central processing unit and also providing quantized voice messages which are synthesized from voice data received, voice memory for providing again to the voice synthesizer the voice data which is in advance stored in adequate format responsive to the address signals supplied from the voice synthesizer, voice output amplifying means for receiving the quantized voice messages supplied from the voice synthesizer for reshaping to smooth waveforms and amplifying to an adequate level, a host computer having a control program for controlling a plurality of slave fire control systems which are coupled to the host computer itself for detecting the fire alarm signal from each central processing unit and providing the fire alarm signal to remaining slave fire alarm systems.
A sensing decorative tree includes a pot provided with a raised annular member on the bottom and a plurality of protuberances on the inner side, a trunk having a lower end engaged with the raised annular member of the pot, a partition plate mounted on the protuberances of the pot, an artificial lawn mounted on the partition plate, a voice producer mounted on the bottom of the partition plate, an amplifier mounted on the pot and electrically connected with the voice producer, a sleeve inserted in the upper outlet of a passage of the trunk, a sensing wire provided at one end with a plug connected with the voice producer and at the other end with a sensor received in sleeve, a volume control mounted in the pot and electrically connected with the amplifier for controlling volume of the amplifier, and a plurality of flexible canes twisted on the trunk and provided at one end with a plug electrically connected with the voice producer and at the other end with a sensor.
A flash and voice warning system generally comprises a power supply with charging circuit, a smoke sensor power supply and auto reset circuit, a smoke sensor (or manual operation), a circuit for converting current to voltage, a single-chip microprocessor, a 60 Hz square wave generator, a control circuit, a buffer, a current amplifier, a high-voltage circuit, N-discharge tube circuits, N-triggering circuits, a flash lamp direction control circuit, and a voice circuit. The smoke sensor is arranged in an appropriate position of a building and the other circuits are mounted within a control box made of fire-proof material. Hence, the flash and voice warning system for fire accidents can direct people where to flee from the fire in case of fire accidents.
A voice warning system for fire accidents including a plurality of fire sensors, a first multiplex selector, a detecting and scanning circuit, a locking circuit, a decoding circuit, a memory circuit, a second multiplex selector, a scanning circuit, a load, a time pulse controlling circuit, a fire emergency assistance calling circuit, and a plurality of loudspeakers 12, the sensors and the loudspeakers being designed to arrange in appropriate positions and the other circuits being disposed with a fire-proof control box, whereby in case of a fire accident, the system will give fleeing instructions to all people in a building through the loudspeakers and will automatically call the fire emergency assistance at the same time.
A sound generation device used in a public space generates tone data corresponding to a change in environment such as environmental noise, temperature, brightness, and the like. The sound generation device includes a detector for detecting environmental noise, temperature, brightness, and the like, and forms tone control data on the basis of the detected environment information. Tone parameters to be supplied to a tone generation LSI or a sound effect DSP are controlled according to the tone control data, thereby selecting and controlling a play No. of tone sources, tone color, tone volume, tempo, reverberation, and the like of tones or music tones to be generated.
A ROM part (24) of a charactor ROM (21) stores a plurality of font data. A display data RAM (9) simultaneously supplies a plurality of address signals to the charactor ROM (21) which is provided with a plurality of address decoders (25, 26). Respective address signals are decoded by the corresponding address decoders (25, 26), so that the font data corresponding to the address signals are read on the common bit lines (BL.sub.1 -BL.sub.l). Thus, the font data as read are synthesized on the common bit lines (BL.sub.1 -BL.sub.l) as a logical sum.
