Definitions

  • the present invention relates to visual communication systems using updatable price tags for goods displayed in retail sale shops.
  • Price tags are commonly supported by pins, stands or other card holding devices that may be placed directly on meat cuts, forms of cheese, small goods, precooked foods and the like.
  • each updatable price tag has an alphanumeric liquid crystal display, a circuitry comprising a receiver of electromagnetic signals, a circuit coupled to said receiver converting the decoded or demodulated signals received into logic signals, a processing circuit of said logic signals controlling a driving stage of the liquid crystals displays and a power supply battery.
  • Setting and updating of the displayed price is made by the use of a battery powered remote control, equipped with a keyboard to key in the updating information, a processing circuit of the signals produced through the keyboard, and a transmitter stage of electromagnetic signals modulated by the signals as processed by said processing circuit.
  • the updating remote control itself is furnished with an alphanumeric liquid crystals display showing the data set through the keyboard.
  • the carrier signal may be a radio frequency (RF) signal, or an optic signal for example of wavelength in the infrared range (IR).
  • RF radio frequency
  • IR infrared range
  • the price setting-updating remote control may be structured in general terms like a familiar remote control of a TV or HF apparatus, with the due differences, while each battery powered price tag incorporates the receiving, decoding and processing circuits that control the setting-updating of the relative alphanumeric liquid crystal display (LCD.)
  • LCD liquid crystal display
  • each battery powered price tag of the system of the present invention can be realized even with a different exterior appearance from that the sample shown.
  • each price tag 1 is equipped with an alphanumeric liquid crystals display 2 of six or more figures, to permit the updating of both the currency and the price, as well as of an eventual reference to the weight or items number.
  • the price tag may be conveniently furnished with one or more transparent pockets 3 and 4, into which may be inserted, in a conventional manner, one or more printed labels or cards for showing specifications, provenience and other details of the good and/or promotional messages.
  • the body of the price tag 1 is essentially a box 5 of molded plastic material, sealably closed in a substantially permanent manner in order to prevent infiltration of fluids, juices, washing solutions, disinfecting liquids, and the like.
  • the electromagnetic signals are radio frequency (RF) signals
  • the body of molded plastic material of the price tag is in itself perfectly transparent to such signals and it will not be necessary the presence of any "window" 6, but the circuitry within the box like body 5 will be perfectly suitable to receive the RF signals.
  • the block RECEIVER detects and demodulates the electromagnetic signals destined to it, and beside a specific transducer, for example a RF signals antenna or a phototransistor or photodiode in case of (IR) signals, the block includes converter circuits that may be of the heterodyne type as in a common radio receiver or of a different type depending on the nature of the signals employed for the transmission via ether as well as detecting and demodulating circuits and circuits for amplifying the signals received.
  • a specific transducer for example a RF signals antenna or a phototransistor or photodiode in case of (IR) signals
  • the block includes converter circuits that may be of the heterodyne type as in a common radio receiver or of a different type depending on the nature of the signals employed for the transmission via ether as well as detecting and demodulating circuits and circuits for amplifying the signals received.
  • the demodulated or detected signals, properly amplified are converted in logic signals by the LOGIC REGENERATION block, so that they can be processed by a logic processing block that can incorporate a microprocessor and a driving stage of the alphanumeric liquid crystals display of the price tag (CPU & LCD DRIVER)
  • a rechargeable or periodically replaceable battery powers all the circuital blocks as well as the LCD DISPLAY
  • Fig. 3 shows the external appearance of a remote control for setting the visual communication implements of the system of the present invention.
  • the remote control T is also furnished with an LCD display which is useful for the operator to set and check the data that are thereafter transmitted upon an enter command to an updatable price tag of Figures 1 and 2.
  • the remote control is furnished with an essential keyboard for composing the alphanumeric price string as well as any other updatable data to be displayed on the price tag.
  • the keyboard constitutes the input device of the data that are then processed by the CPU & LCD DRIVER, that may include a microprocessor and driving circuits for the alphanumeric liquid crystals display, reproducing on the display the set alphanumeric string.
  • the set data signals are eventually sent to the RF or IR TRANSMITTER.
  • the same digital data that drive the LCD display constitute in fact the modulating signals that are eventually sent to the transmitter block, which may contain conventionally a carrier wavelength generating circuit, a modulating stage of the carrier frequency or of the carrier wavelength in function of the digital signals received from the processing circuitry, and a power stage driving a transmission antenna for a modulated RF signal or optical device for emitting a modulated IR signal.
  • the modulation of the carrier frequency is of a digital type, realized for example in a pulse width modulation (PWM) mode which is relatively simple to implement and particularly reliable, though any other method of modulation may be alternatively used.
  • PWM pulse width modulation
  • both the antenna A of the transmitter and the receiving antenna inside the price tags will be highly directional in order to facilitate the one-by-one updating, in an essentially independent way of a plurality of price tags that often may be disposed necessarily close to each other.
  • the electromagnetic signals are optical or IR signals
  • the directionality would be relatively intrinsic and eventually increased by lenses and/or diaphragms in either the transmitter and/or the receiver, thus requiring an alignment of the two during the transfer of the updated data, set on the remote control and eventually transmitted to the receiver price tag by a transmission command.
  • system of visual communication of the present invention may be implemented in different ways or embodiments similarly to the remote control of TV sets and the like.
  • the circuits and the transducers used to realize the price tag receivers as well as the remote updating transmitter will depend upon design choices.
