Abstract
Abstract A system shopping cart for use in multi-department self-service stores is shown and described. The cart includes a digital memory for storing information specific to a department. Information is transferred to the cart by infrared light transmission coming from transmitters located in each department. The cart includes a display which provides a visual message for the cart user, and also includes an infrared transmitter for transmitting information to a department infrared transceiver for the purpose of identifying cart location and time for the purpose of customer shopping pattern analysis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
342 words
A system for supplying a preselected number of different departments of a large self-service store with department-specific information, said system comprising: a plurality of system shopping carts moveable between a plurality of different departments of a large self-serve store; a first infrared transceiver (5) with a memory, located in each of a preselected number of said plurality of different departments (2), each said first infrared transceiver responsive to encoded infrared signals to store information in said memory, to transmit said stored information from said memory by encoded infrared signals, and to store information confirming receipt of said transmitted information in said memory; a mobile cart; information storage, delivery and collection means for a) storage of department-specific information for each of said preselected number of different departments, b) respective delivery along a first infrared path (6") of said department-specific information to each corresponding first infrared transceiver (5) and c) collection along a second infrared path (6'") of information confirming receipt of said department-specific information by system shopping carts (7) entering said preselected number of different departments; said information storage, delivery and collection means comprising a computer (1) and a second infrared transceiver (3) mounted on said mobile cart to permit said information storage, delivery and collection means to be physically moved between said preselected number of said plurality of different departments for delivery of said department-specific information to each said first infrared transceiver corresponding to each said different department and collection of information confirming receipt of said department specific information by said system shopping carts; and a third infrared transceiver (8) having a display and an internal memory mounted on each of said plurality of system shopping carts (7) on a front upper edge of baskets of said system shopping carts (7); wherein said first infrared transceiver (5) delivers said department-specific information to said third infrared transceiver (8) along a third infrared path (6) for activating said display in a predetermined cycle on entry of one of said plurality of system shopping carts (7) into one of said preselected number of different departments.
Claim 2
Independent Claim

A system for supplying a preselected number of different departments of a large self-service store with department-specific information, said system comprising: a plurality of system shopping carts moveable between a plurality of different departments of a large self-serve store; a first infrared transceiver (5) with a memory, located in each of a preselected number of said plurality of different departments (2), each said first infrared transceiver responsive to encoded infrared signals to store information in said memory, to transmit said stored information from said memory by encoded infrared signals, and to store information confirming receipt of said transmitted information in said memory; a mobile cart; information storage, delivery and collection means for a) storage of department-specific information for each of said preselected number of different departments, b) respective delivery along a first infrared path (6") of said department-specific information to each corresponding first infrared transceiver (5) and c) collection along a second infrared path (6'") of information confirming receipt of said department-specific information by system shopping carts (7) entering said preselected number of different departments; said information storage, delivery and collection means comprising a computer (1) and a second infrared transceiver (3) mounted on said mobile cart to permit said information storage, delivery and collection means to be physically moved between said preselected number of said plurality of different departments for delivery of said department-specific information to each said first infrared transceiver corresponding to each said different department and collection of information confirming receipt of said department specific information by said system shopping carts; and a third infrared transceiver (8) having a display and an internal memory mounted on each of said plurality of system shopping carts (7) on a front upper edge of baskets of said system shopping carts (7); wherein said first infrared transceiver (5) delivers said department-specific information to said third infrared transceiver (8) along a third infrared path (6) for activating said display in a predetermined cycle on entry of one of said plurality of system shopping carts (7) into one of said preselected number of different departments.
Claim 3
Dependent Claim
37 words
The system according to claim 1, wherein said third infrared transceiver (8) transmits confirmation of each activation of said display by said department-specific information along a fourth infrared path (6') to said first infrared transceiver unit (5).
Claim 4
Dependent Claim
20 words
The system according to claim 1, wherein said display (9) is a four-line display for 40 alphanumeric characters per line.
Claim 5
Dependent Claim
28 words
The system according to claim 1, wherein said third infrared transceiver (8) automatically transmits a code number via said fourth infrared path to said first infrared transceivers (5).
Claim 6
Dependent Claim
53 words
The system according to claim 1, wherein said first infrared transceivers (5) broadcast a location identification code over said third infrared path to each of said third infrared transceivers (8) and each said third infrared transceiver (8) utilizes said internal memory for storing the location identification code of said first infrared transceiver (5).
