Abstract
A method and apparatus for determining the location of an object. An object to be located can be provided with an object locator that includes a display. When the object locator receives a signal indicating that the object associated with the object locator is to be located, the display changes display state to provide a visual indication that the signal has been received. The object locator can be ambient energy-powered, and the display can be a bistable display, such as a rotating element display device.
