SMART GONDOLA SYSTEM

1 . A gondola system in a retail store, comprising:

at least one gondola, wherein the at least one gondola is comprised of one or more shelves, wherein a set of items are attached to the one or more shelves, wherein a set of weight sensors are placed on each corner of the at least one gondola, wherein the set of weight sensors are configured to measure weight data, wherein the set of weight sensors are placed at the each corner of the at least one gondola, wherein the set of weight sensors comprises at least two weight sensors;

a data processing device coupled to the set of weight sensors, wherein the data processing device is configured to calculate weight and change in weight by combining the weight data from the each corner of the at least one gondola, wherein the data processing device is configured to determine location of an item removed or placed by calculating the location based on changes of weight data at the each corner of the at least one gondola and some input from a camera system that is coupled to the data processing device;

a set of indicators coupled to the gondola system, wherein each of the set of indicators is placed under each item coupled to the gondola system, wherein the each of the set of indicators is configured to blink when the each item above the each of the set of indicators is removed; and

a remote server coupled to the data processing device and the set of cameras via a network, wherein the remote server is configured to receive information of the location of the item removed or placed from the data processing device.

2 . The gondola system of claim 1 , wherein the network is connected by Ethernet.

3 . The gondola system of claim 2 , wherein the set of weight sensors and the camera system are using power over Ethernet.

4 . A gondola system in a retail store, comprising:

at least one gondola, wherein the at least one gondola is comprised of one or more shelves, wherein a set of items are attached to the one or more shelves, wherein a set of weight sensors are placed on each corner of the at least one gondola, wherein the set of weight sensors are configured to measure weight data placed at the each corner of the at least one gondola;

a data processing device coupled to the set of weight sensors, wherein the data processing device is configured to calculate weight and change in weight by combining the weight data from the each corner of the at least one gondola, wherein the data processing device is configured to determine location of an item removed or placed by calculating the location based on changes of weight data at the each corner of the at least one gondola and some input from at least three cameras that are coupled to the data processing device in the retail store, wherein at least one of the at least three cameras is configured to detect infrared;

a remote server coupled to the data processing device and the set of cameras via a network, wherein the remote server is configured to receive information of the location of the item removed or placed from the data processing device; and

a set of visual indicators coupled to the at least one gondola, wherein the set of visual indicators are coupled to blink to identify the geo-location of the at least one gondola, wherein the set of visual indicators are configured to blink pre-determined patterns to convey digital data to the remote server via the set of cameras, wherein one type of the digital data is unique ID of the at least one gondola, wherein the unique ID is related to the physical location of the at least one gondola, wherein the set of visual indicators are configured to direct a shopper to a specific item the shopper has purchased before, or an item on the shopper's request, or an item that has a special discount.

5 . The gondola system of claim 4 , wherein the network is connected by Ethernet.

6 . The gondola system of claim 5 , wherein the set of weight sensors and the at least three cameras are using power over Ethernet.
