  • Patent number: 6354498
    Abstract: A method of operating a self-service checkout terminal includes the step of detecting an improper-terminal-use activity and generating an improper-use control signal in response thereto. The method also includes the step of operating a status device in a first mode of operation in response to generation of the improper-use control signal. The method further includes the step of updating an electronic log value in response to generation of the improper-use control signal. Moreover, the method includes the step of generating a first intervention signal if the log value has a predetermined relationship to a log threshold. The method also includes the step of operating the status device in a second mode of operation in response to generation of the first intervention control signal, wherein the first mode of operation is different from the second mode of operation.

  • Patent number: 6215078
    Abstract: A method of operating a retail terminal having a weight scale associated therewith includes the step of executing a security software application so as to provide security to the retail terminal during operation thereof. The method also includes the step of determining a current weight value associated with output from the weight scale. Moreover, the method includes the step of comparing the current weight value to a previous-stable-weight value and generating a weight change control signal if the current weight value is not within a predetermined tolerance range of the previous-stable-weight value. Yet further, the method includes the step of utilizing the current weight value during execution of the security software application in response to generation of the weight change control signal. A retail checkout terminal is also disclosed.

  • Patent number: 6155486
    Abstract: A method of operating a self-service checkout terminal having a scanner device for allowing a user to enter an item for purchase, and a weight scale for detecting placement of the item for purchase in a post-scan area associated with the self-service checkout terminal includes the step of generating an item-entered control signal when the user scans the item for purchase with the scanner device. The method also includes the step of disabling the scanner device in response to generation of the item-entered control signal. Moreover, the method includes the step of generating an item-not-detected control signal if the weight scale does not detect placement of the item for purchase in the post-scan area within a first predetermined period of time subsequent to generation of the item-entered control signal. Yet further, the method includes the step of enabling the scanner device in response to generation of the item-not-detected control signal. A self-service checkout terminal is also disclosed.

  • Patent number: 6080938
    Abstract: A method of resetting a product scale of a retail checkout terminal includes the step of detecting absence of an item on the product scale. The method also includes the step of generating an absence signal in response to the detecting step. The method further includes the step of determining a first idle value with the product scale. The method also includes the step of comparing the first idle value to a reset value. Moreover, the method includes the step of generating a first control signal if the first idle value matches a reset value. The method also includes the step of generating a second control signal if the first idle value does not match the reset value. Yet further, the method includes the step of resetting the product scale in response to generation of the second control signal. An apparatus for resetting a product scale of a retail checkout terminal is also disclosed.

  • Patent number: 5967264
    Abstract: A method of monitoring item shuffling in a post-scan area of a self-service checkout terminal having a post-scan shelf, a bagwell with a grocery container positioned therein, and a weight scale positioned so as to detect weight of items positioned both on the post-scan shelf and in the grocery container, includes the step of detecting removal of a first number of items from the post-scan shelf with the weight scale and generating a first weight decrease value in response thereto which corresponds to the weight of the first number of items.

  • Patent number: 5233339
    Abstract: A method and circuit for controlling the contrast of a liquid crystal display (LCD). The circuit includes a switching regulator circuit which generates a negative voltage at the output thereof, with the switching regulator circuit having a feedback node therein and also having a voltage regulator with a control input therein. An injected current coupled to the feedback node and the control input to the voltage regulator is used to provide a changed negative voltage at the output of the regulator circuit. Control values stored in the memory of a controller are used to select the injected current. The changed negative voltage at the output of the regulator circuit is used to control the contrast of the LCD.
