The present invention describes various methods and apparatus to increase
efficiency and sales of a Newspaper Rack. At least one sensor is
positioned within a Newspaper Rack to monitor when the remaining
inventory of Newspapers reaches a predetermined quantity (including
depleted). A logic circuit monitors when the sensor(s) change state then
directs a signal to be transmitted to a central location. The central
location may add time-stamping, reference the location, and compile the
information into a database. The central location notifies the proper
party to service the Newspaper Rack. The Newspaper Rack can include
various mechanisms to stimulate customers into purchasing a Newspaper,
such as a visual display or audible means. The stimulating information
can be obtained and/or changed using wireless transmission to a receiver.
The Newspaper Rack can include external monitoring devices to gather
information for traffic flow, weather, or other desirable information.
This can offset the service costs for monitoring the inventory levels.
Power consumption and replenishment are considered by the inclusion of
solar cells or a generator to recharge the battery, placement of the
battery under the platform for ease of replacement, the inclusion of a
battery monitoring circuit for optimizing replacement, and a power
conservation logic circuit which turns off non-essential tasks while
continuing to monitor the sensors.
