Abstract

Un sistema que comprende varios trasmisores en sitios fijosen un supermercado y un receptor móvil instalado en cada chango. Cuando un chango penetra en el alcance de un transmisor, se establece un vínculo entre ambos para pasar al receptor un mensaje de audio pregrabado en el transmisor para ser oído por el usuario del chango. Los receptores irradian sus señales de control de "escucha" con un alcance predeterminado en respuesta a lo cual un transmisor dentro del alcance de uno de tales receptores devuelve una señal de control de "envió" u trasmite su mensaje pregrabado que es sintonizado por el receptor, las señales de control son señales monofrecuentes que modulan portadoras infrarrojas. Las señales de los mensajes están grabados preferentemente en memorias analógicas de estado sólido y modulan en frecuencia portadoras de radio o infrarrojas en distintas realizaciones. Otros usos incluyen museos y ambientes públicos, donde un tal receptor puede ser portado por el usuario en lugar de instalado en un chango.A system that includes several transmitters at fixed sites in a supermarket and a mobile receiver installed in each monkey. When a monkey enters the range of a transmitter, a link is established between the two to pass a pre-recorded audio message to the receiver on the transmitter to be heard by the user of the monster. The receivers radiate their "listen" control signals with a predetermined range in response to which a transmitter within range of such a receiver returns a "send" control signal and transmits its prerecorded message that is tuned by the receiver. , the control signals are monofrequent signals that modulate infrared carriers. The message signals are preferably recorded in solid state analog memories and modulate radio or infrared carrier frequencies in different embodiments. Other uses include museums and public settings, where such a receiver can be carried by the user rather than installed in a loft.
