Claim 10
Independent Claim
174 words
A method of operating a retail checkout terminal, comprising the steps of: providing a scanner for scanning a first item of a user's items for purchase; providing a product scale for weighing a second item of the user's items for purchase, wherein (i) the product scale includes an upper surface, and (ii) the product scale is configured to determine weight of the second item when the second item is positioned in direct contact with the upper surface; detecting absence of the second item on the upper surface of the product scale and generating an absence signal in response thereto; determining a first idle value with the product scale in response to generation of the absence signal; comparing the first idle value to a reset value after the detecting step; generating a first control signal if the first idle value matches a reset value; generating a second control signal if the first idle value does not match the reset value; and automatically resetting the product scale in response to generation of the second control signal.
Claim 11
Independent Claim
174 words
A method of operating a retail checkout terminal, comprising the steps of: providing a scanner for scanning a first item of a user's items for purchase; providing a product scale for weighing a second item of the user's items for purchase, wherein (i) the product scale includes an upper surface, and (ii) the product scale is configured to determine weight of the second item when the second item is positioned in direct contact with the upper surface; detecting absence of the second item on the upper surface of the product scale and generating an absence signal in response thereto; determining a first idle value with the product scale in response to generation of the absence signal; comparing the first idle value to a reset value after the detecting step; generating a first control signal if the first idle value matches a reset value; generating a second control signal if the first idle value does not match the reset value; and automatically resetting the product scale in response to generation of the second control signal.
Claim 12
Dependent Claim
56 words
The method of claim 9, further comprising the steps of: determining a second idle value with the product scale in response to the resetting step; generating the first control signal if the second idle value matches the reset value; and regenerating the second control signal if the second idle value does not match the reset value.
Claim 13
Dependent Claim
31 words
The method of claim 10, further comprising the step of generating a message which instructs an attendant to service the product scale in response to regeneration of the second control signal.
Claim 14
Dependent Claim
22 words
The method of claim 9, wherein the detecting step includes the step of detecting absence of the item with a video system.
Claim 15
Dependent Claim
103 words
A retail checkout terminal, comprising: a scanner for scanning a first item of a user's items for purchase; a product scale for weighing a second item of said user's items for purchase; means for detecting absence of said second item on said product scale and generating an absence signal in response thereto; means for determining a first idle value with said product scale in response to said absence signal; means for comparing said first idle value to a reset value after said absence signal is generated; and means for generating a first control signal if said first idle value matches said reset value.
Claim 16
Dependent Claim
103 words
A retail checkout terminal, comprising: a scanner for scanning a first item of a user's items for purchase; a product scale for weighing a second item of said user's items for purchase; means for detecting absence of said second item on said product scale and generating an absence signal in response thereto; means for determining a first idle value with said product scale in response to said absence signal; means for comparing said first idle value to a reset value after said absence signal is generated; and means for generating a first control signal if said first idle value matches said reset value.
