A panel apparatus comprises a tongue-in-groove connection connecting first and second panels. To improve response rate, the listing agent can add incentives to other agents who provide useful feedback. Each converter is able to convert received electromagnetic signals into electronic signals, which it then may relay to leads on the device on which it is disposed; and receive electronic signals from leads on the device on which it is disposed and convert them into corresponding electromagnetic signals, which it may transmit to a corresponding converter on the other device. On the part of the communications device, an image object is selected based on the transmitted image, and a position of this image object is determined. Lastly, the flexible circuit is electrically connected to the etched exposed surface.
