发明名称 Method and apparatus for locating electronic shelf labels
摘要 Systems and techniques for locating designated electronic shelf labels. A locator device transmits commands to a designated label, causing a label to take on distinctive characteristics, for example showing a characteristic display. Alternatively or in addition, the locator device detects transmissions from labels within range and provides an indication, such as an audible tone or a serial number display, when an identified label is within range. A user may enter a serial number of one or more labels using a keypad, or may upload one or more serial numbers to the locator device. The user then moves with the locator device around a location where labels are in use. Depending on the design of the device, the device broadcasts commands to labels to cause the labels to take on identifiable characteristics, detects serial numbers of labels based on transmissions from labels within range, or both.
