Shopping cart retrieval system with award signal generation based on a predetermined count
First Claim
1. For use with a store having a plurality of shopping carts, a system for encouraging people to return the shopping carts to a designated area comprising:
- a target attached to each of a plurality of shopping carts;
a single counter, said single counter being operable between a first and second predetermined limit;
means coupled to said single counter for varying said first predetermined limit and presetting said single counter to said first predetermined limit, said first predetermined limit being a user selected limit;
means for detecting said target on each shopping cart when returned to the designated area and for generating an output signal representative thereof;
means interconnecting said single counter and said detecting means and responsive to said output signal for changing the count in said single counter by a predetermined increment toward said second predetermined limit;
means connected to said single counter for detecting when the count in said single counter reaches said second predetermined limit and for generating a detector output signal whenever said count in said single counter reaches said second predetermined limit;
an award signal generating means; and
means interconnecting said detecting and generating means and said award signal generating means and responsive to said detector output signal for activating said award signal generating means,whereby the last one of a predetermined count of shopping carts returned to the designated area activates the award signal generating means.

Abstract
A system for retrieving shopping carts at a store having a plurality of shopping carts is disclosed. The system includes a counter which can be preset to a first determined count. A target is mounted to each shopping cart while a sensor detects the return of each shopping cart to a designated area. As each shopping cart is returned to the designated area, the sensor generates an output pulse which changes the count in the counter. Whenever the count in the counter achieves a second predetermined count, an alarm is activated indicative that a prize is awarded to the person returning the shopping cart to the designated area.

4. A shopping cart retrieval system for encouraging the return of shopping carts to a designated area, comprising:
-
a target mounted to each of a plurality of shopping carts; means for sensing said target on each of the plurality of shopping carts returned to the designated area and for generating an output signal for each said target sensed; a single counter connected to said sensing means for counting each said output signal from said sensing means; means coupled to said single counter for presetting said single counter to a first and second predetermined count; means connected to said single counter for detecting said single counter reaching said second predetermined count; an alarm; means interconnecting said alarm and said detecting means for activating said alarm in response to said detecting means detecting said second predetermined count, whereby the last one of a predetermined count of shopping carts returned to the designated area activates the alarm. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. A shopping cart retrieval system, comprising:
-
a plurality of shopping carts; a target mounted to each of said plurality of shopping carts; a sensor located adjacent a designated area to sense said target of each of said plurality of shopping carts passing thereby when returned to the designated area and generating an output signal in response thereto; an amplifier connected to said sensor for amplifying said output signal; a wave shaper connected to said amplifier receiving a signal from said amplifier; a single counter connected to said wave shaper for counting each said signal from said wave shaper; a reset circuit connected to said single counter to preset said single counter to a first predetermined count; a plurality of switches on said reset circuit to vary said first predetermined count on said single counter; a detector circuit connected to said single counter to generate a signal in response to said single counter reaching a second predetermined count; an alarm driver circuit connected to said detector circuit to receive said signal from said detector circuit; and an alarm which is activated by said alarm driver circuit, whereby the last one of a predetermined count of shopping carts returned to the designated area activates the alarm.
