Abstract

A system for holding one or more bags. The system includes a cart, a first chute disposed on the cart, and a second chute also disposed on the cart. The first chute includes a first edging along each side of the first chute. The second chute includes a second edging along each side of the second chute. The second chute is intertwined with the first chute. The system may further include a third chute and a fourth chute disposed on the cart. The third chute may include a third edging along each side of the third chute, and the fourth chute may include a fourth edging along each side of the fourth chute. The top and bottom of the first chute and the top and bottom of the second chute are positioned on opposite ends of the cart at about 180 degrees apart, while the top and bottom of the third chute and the top and bottom of the fourth chute are positioned on opposite ends of the cart at about 180 degrees apart.

First claim

What is claimed is:

1. A method for managing a chute of a baggage cart for holding one or more bags, comprising:
sending a command to a first sensor to project a light beam at the chute, the first sensor comprising an optical sensor pointed towards the baggage cart; and
determining whether the chute is full based on whether the optical sensor receives a reflected light beam from a second sensor within a first predetermined amount of time, the second sensor comprising a reflector positioned on the baggage cart.

2. The method of claim 1 , further comprising determining the identity of the chute based on data embedded in the reflector and the reflected light beam.

3. The method of claim 1 , further comprising:
if it is determined that the chute is full, then sending a command to one or more rotation devices coupled to an outer wall of the baggage cart to rotate the baggage cart until the optical sensor receives the reflected light beam; and
determining that the baggage cart is full if the optical sensor does not receive the reflected light beam within a second predetermined amount of time.

4. The method of claim 1 , wherein the optical sensor is disposed on a post supporting a conveyor belt that transports bags in a baggage handling system.

5. A method for managing one or more chutes of a baggage cart for holding one or more bags, comprising:
(a) sending a command to an ultrasonic sensor to send one or more sound waves to an i th chute; and
(b) determining whether the i th chute is full based on whether the ultrasonic sensor receives one or more reflected sound waves within a first predetermined amount of time.

6. The method of claim 5 , wherein the ultrasonic sensor is disposed on a post supporting a conveyor belt that transports bags in a baggage handling system.

7. The method of claim 5 , further comprising determining that the i th chute is not full if the ultrasonic sensor receives the reflected sound waves after the predetermined amount of time.

8. The method of claim 5 , further comprising determining that the i th chute is full if the ultrasonic sensor detects at least one bag present at the top of the i th chute.

9. The method of claim 5 , further comprising:
(c) if it is determined that the i th chute is full, then sending a command to one or more rotation devices coupled to an outer wall of the baggage cart to rotate the baggage cart until the ultrasonic sensor is in front of an (i+1) th chute;
(d) sending a command to the ultrasonic sensor to send the sound waves to the (i+1) th chute;
(e) repeating steps (c)-(d) for each chute until the ultrasonic sensor receives the reflected sound waves within a second predetermined amount of time; and
(f) determining that the baggage cart is full if the ultrasonic sensor does not receive the reflected sound waves within the second predetermined amount of time.

10. A method for managing one or more chutes of a baggage cart for holding one or more bags, comprising:
(a) sending a command to a vision sensor to acquire an image of an i th chute; and
(b) determining whether the i th chute is full based on whether the image matches a reference image that corresponds to an empty chute.

11. The method of claim 10 , wherein the vision sensor is disposed on a post supporting a conveyor belt that transports bags in a baggage handling system.

12. The method of claim 10 , further comprising:
(c) if it is determined that the i th chute is full, then sending a command to one or more rotation devices coupled to an outer wall of the baggage cart to rotate the baggage cart until the vision sensor is in front of an (i+1) th chute;
(d) sending a command to the vision sensor to acquire an image of the (i+1) th chute;
(e) repeating steps (c)-(d) for each chute until the vision sensor acquires the image that matches the reference image; and
(f) determining that the baggage cart is full if the vision sensor does not acquire the image that matches the reference image.
