Electronic Price Tag

      The concept of a free-standing, portable, electronic price tag
is described.  This electronic price tag includes a power management
scheme and wireless, bidirectional communications to a central
computer.

      The portable electronic price tag is low-power computer, about
the size of a price tag, that can be placed anywhere in a store.
This computer is little more than a liquid crystal display faceplate
with microchip circuitry behind it.  The display will present the
price and a brief description of the product.

      Two key technical aspects of the portable electronic price tag
are that it be able to run on solar panels (or a combination of solar
and rechargeable battery power) and that it has two-way, wireless
communication with the host computer.  Independent power source and
wireless communications are needed for the devices to be completely
portable - easily moved with no installation wiring costs.  A likely
communication mechanism would be infrared light-emitting diodes
(LEDs).  An array of LED sensors and emitters could be installed
across the store ceiling to ensure each tag is accessible.

      Price changes entered into the central computer can be
automatically distributed to the store floor either off-hours or
along with a store-wide announcement of a price change.  Update
information is sent to the portable electronic price tag and the unit
responds to let the system know the shelf has actually been updated....
