SYSTEM AND METHOD FOR ALERTING AN OPERATOR
 This application claims the priority benefit of U.S. Patent Application No. 1 1/696,392, filed April 4, 2007, which is hereby incorporated by reference in its entirety.
BACKGROUND AND SUMMARY OF THE EXEMPLARY EMBODIMENTS  The exemplary embodiments relate generally to weighing apparatus having a user interface. More specifically, the exemplary embodiments relate to weighing apparatus having at least one operator interface, which may be adapted to display a message to an operator.
 Weighing apparatus are well known. Presently, weighing apparatus are used in a variety of applications. For example, weighing apparatus may be used in retail and industrial applications. One exemplary retail application may be at a grocery store, such as in the grocery's deli, bakery, meat department or produce department. The weighing apparatus used in these applications may be capable of weighing a product and displaying the weight, unit price, total price and other information associated with the product. Such weighing apparatus may have a user interface that may allow the operator to perform one or more actions. These actions may include printing labels, looking up a price, looking up a PLU, overriding a transaction, voiding a transaction, administering to the weighing apparatus and other similar actions.
 Currently, there is not an effective way of communicating information with operators of the weighing apparatus, for example, employees of a grocery store.
Examples of information that may be communicated to users may include price changes, product additions, product recalls, product relabelling, instructions to employees and any other similar information. Presently, this information may be communicated through telephone calls, paper announcements on employee bulletin boards and/or intranet websites. These methods each have their own shortcomings. For example, telephone calls may or may not be answered due to the operators assisting customers; bulletin boards may or may not be reviewed by operators and if they are reviewed may not be reviewed on a timely basis; and intranet websites may not be viewed due to the fact that a separate personal computer must be utilized, which may not be in the same location as the weighing apparatus. Furthermore, each of these methods requires the operator to be away from the weighing apparatus to review the message. Having the operator away from the weighing apparatus means the operator is not available to assist customers, which may lead to unhappy customer and loss of sales.
 The exemplary embodiments described below attempt to overcome or reduce these problems. The exemplary embodiments may be directed to a weighing apparatus. The weighing apparatus may have a platform that may to receive an object to be weighed and an operator display associated with the platform. A user interface, having a plurality of areas, at least one of the areas being a message area, may be presented on the operator display. A device may be connected to the weighing apparatus and may send a command to the weighing apparatus. The command may cause a message to be displayed in the message area of the operator display. This allows the operators to receive important messages at the weighing apparatus, so that they may remain near the customer. The messages
may also be more likely to be seen since the operator spends a large amount of their time in front of the weighing apparatus and operator display.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT(S)  Figure 1 illustrates one exemplary embodiment of a weighing apparatus 100. The weighing apparatus 100 may have a force-measuring device (not shown) and platform 102. The force-measuring device may assist in determining the weight of an item that may be placed on the platform 102, as is known in the art. The force- measuring device can be any force-measuring device known in the art such as, but not limited to, a load cell. The weighing apparatus 100 may include an operator display 104. The operator display 104 can be integrated into the weighing apparatus
100 or be a standalone unit. The operator display 104 may generally face the operator of the weighing apparatus. The operator display 104 may be any display known in the art. For example, the operator display 104 can be a VF display, an LCD, a touch screen or any other similar display. The operator display 104 shown in Figure 1 is a touch screen display. If a touch screen display is not used then it should be apparent that the operator display 104 could be coupled to one or more input devices such as, but not limited to, a keyboard, keypad, mouse or other similar input device. The operator display 104 may present a plurality of user interfaces 200, which will be discussed in more detail below. The weighing apparatus 100 may also include a customer display 106. The customer display 106 may generally face the customer. The customer display 106 may also be any display known in the art. The weighing apparatus 100 may contain a controller 1 10. The controller 1 10 may be a programmable device capable of receiving and executing commands. Any controller known in the art may be used in the weighing apparatus 100. For example, the controller 1 10 may be an integrated processor with memory, a personal computer running a WINDOWS operating system or any other similar configuration. In one exemplary embodiment, a database 1 12 may be included in the weighing apparatus 100. The database 112 may store the commands that may be sent to the weighing apparatus 100.
 As stated above, the operator display 104 may present one or more user interfaces 200. The user interfaces 200 may have a plurality of defined areas 202. One such exemplary user interface 200, such as the PLU transaction interface 204 shown in Figure 2, may have the following defined areas: keypad area 206, page preset area 208, preset tab area 210, weight area 212, PLU area 214, date and time
area 216, admin area 218 and message area 220. Other interfaces with other defined areas are also possible. The defined areas 202 may present a subset of data to the operator which may be used in a plurality of functions. For example, the weight area 212 may present the weight of the item being weighed on the platform 102. The message area 220 may display a message to the operator, which may be sent from a remote location.
 As shown in Figure 3, the weighing apparatus 100 may be connected to a network 300, such as a LAN, WAN or the Internet, for communicating with computers 302, servers 304 and/or weighing apparatus 306 connected to the network 300. The computers 302 may also be handheld devices, such as, but not limited to, PDAs, cell phones and similar devices. The computers 302, servers 304 and/or weighing apparatus 306 may be wired or wirelessly connected to the network 300. The network 300 may include weighing apparatus, computers and servers that may be disposed in a single department, multiple departments, a single store, multiple stores, or an entire company. The network 300 may allow a central location to send messages to thousands of weighing apparatus 100 around the world in a single command. In one exemplary embodiment, a database may be connected to the network for storing the commands and messages.
 As illustrated in Figure 4, during normal operation of the weighing apparatus, the message area 220 may be blank. A command may be sent to the weighing apparatus 100. Upon receiving the command, a message 222 may be displayed in the message area 220. The command may be sent over the network 300 from a computer 302, a server, 304 or another weighing apparatus 306. The message may be any message, for example, a simple text string, a message alerting
the operator that pricing has changed, a product has been recalled and/or a product has been added or deleted, a message directing the operator to an intranet posting for further information or any other similar message. The message may be displayed for a predetermined period of time, until another command is sent to turn off the message, until another command is sent to display a new message and/or until the message is cleared by the operator by pressing a button or similar operation. The message may be set to be displayed at a single weighing apparatus, all weighing apparatus or a subset of the weighing apparatus. The subset may be selected from a list of all of the weighing apparatus in a store or company, or the subset may be grouped by department and a single, a subset or all departments may be selected.
 In another exemplary embodiment, the command may also include a task that may be required to be performed before the message may be cleared. For example, the message may be to remove all of a certain product from the shelves. Once the operator accomplishes the task, the operator may clear the message. Information, such as the message, the person clearing the message and the time the message is cleared may be entered into the database for tracking purposes. The command may also include an alert for changing prices. The alert may be selected and a batch mode run to change the prices.
 In yet another exemplary embodiment, the message area 220 or message 222 may be selected and another action may be performed. For example, the operator could select the message area or message using the touch screen or other input device, like a mouse, keyboard or keypad. In response to selecting the area or message, the weighing apparatus may run a macro, launch an application, such as a
web browser, and/or display another message area with additional text or tasks. Each of these steps may be entered into the database for tracking.  While certain exemplary embodiments are described in detail above, the scope of the invention is not to be considered limited by such disclosure, and modifications are possible without departing from the spirit of the invention as evidenced by the following claims:
