Described herein are several solutions that increase transducer lifetime by reducing or preventing tear propagation in a compliant electroactive polymer. The packet metric parameter which might comprise the volume of packets received is analysed over selected time intervals with respect to specified geographical locations in which the hosts transmitting the packets are located. A compact terminal apparatus is connected to the seat terminal apparatus via a terminal apparatus transmission path, and receives and displays at least the video data, and a display terminal apparatus receives the video data from the compact terminal apparatus and display the data. Lastly, the method comprises calibrating each detector by applying the discretized crystal adjustment value for each crystal in each detector to the collected timing data indicative of coincidence events. The IDC configuration message is sent to the wireless communication device.
