Abstract

A retail terminal includes a scale for weighing items to be purchased. The scale is operative to obtain a settled or stable weight of items placed thereon either after a predetermined time delay from when the items were placed on the scale or the receipt of an actuation signal from a trigger or actuator. This allows time for the scanning of an item of the items on the scale via a scanner of the retail terminal generally associated with the lifting of the item from the scale in order for the item to be scanned.

Claims

1. A method of operating a retail terminal comprising the steps of:

allowing placement of items to be weighed on a scale of the retail terminal;

allowing scanning of one item of the items via a scanner of the retail terminal;

obtaining a first weight measurement of the items on the scale upon successful scanning of the one item; and

obtaining a second weight measurement of the items on the scale upon actuation of a trigger.

2. The method of claim 1, wherein actuation of a trigger comprises sensing a change of weight on the scale.

3. The method of claim 1, wherein actuation of a trigger comprises user-actuation of an actuator.

4. The method of claim 3, wherein actuation of a trigger comprises user-actuation of an actuator comprising a key of the retail terminal.

5. The method of claim 1, further comprising the step of:

initiating a timer after the step of obtaining a first weight measurement, the timer having a time duration; and

wherein the step of obtaining a second weight measurement upon actuation of a trigger includes obtaining a second weight measurement upon the actuation of a trigger or the timer reaching the time duration.

6. The method of claim 1, further comprising the step of:

providing an indication if the second weight measurement has been successfully obtained.

7. The method of claim 6, wherein the step of providing an indication includes providing one of an audio indication and a visual indication.

8. A retail terminal comprising:

a processor;

memory in communication with said processor and containing program instructions operative to control said processor;

a scale in communication with said processor; and

a scanner in communication with said processor;

said scale operative to obtain a first weight measurement of items placed on said scale;

said scanner operative to obtain machine-readable data from one of the items; and

said scale further operative to obtain a second weight measurement of the items on said scale upon receipt of a trigger signal.

9. The retail terminal of claim 8, wherein said trigger signal is generated by said scale sensing a change of weight.

10. The retail terminal of claim 8, wherein said trigger signal is generated by user-actuation of a trigger.

11. The retail terminal of claim 8, wherein:

said processor is operative to initiate a timer after said scale obtains the first weight measurement, the timer having a time duration; and

said scale is further operative to obtain a second weight measurement of the items on said scale upon the scale receiving a trigger signal or the timer reaching the time duration.

12. The retail terminal of claim 11, further comprising:

an indicator in communication with said processor, said indicator operative to provide an indication of a successful attainment of said second weight measurement by said scale.

13. The retail terminal of claim 12, wherein said indicator comprises one of an audio device and a video device.

14. A checkout system comprising:

a processor;

a scale in communication with said processor and operative to obtain weight measurement of items placed on said scale;

a scanner in communication with said processor and operative to read bar codes; and

memory in communication with said processor and containing program instructions which, when executed by said processor, causes said processor to;

obtain a first weight measurement from said scale of items placed on said scale;

obtain a bar code associated with one of said items from said scanner; and

obtain a second weight measurement from said scale of the items placed on said scale upon actuation of a trigger.

15. The checkout system of claim 14, wherein said trigger comprises sensing a weight change by said scale.

16. The checkout system of claim 14, wherein said trigger comprises a user-actuated actuator.

17. The checkout system of claim 14, wherein said memory has further program instructions which, when executed by said processor, causes said processor further to:

initiate a timer after said processor obtains a first weight measurement, the timer having a time duration; and

obtain a second weight measurement from said scale of the items placed on said scale upon actuation of a trigger or said timer reaching said time duration.

18. The checkout system of claim 14, further comprising:

an indicator in communication with said processor, said indicator operative to provide an indication of a successful attainment of said second weight measurement by said scale.

19. The checkout system of claim 18, wherein said indicator comprises one of an audio device and a video device.
