Methods and a related data routing system for handling received data packets that are out of sequence and were previously declared lost. Following receipt of a data packet, it is determined if the sequence number of the received data packet is out of order in comparison to previously received data packets. If the sequence number is out of order, the distance between the out of order sequence number and the sequence number of the last data packet that was received in sequence is calculated. The distance is used to discard or keep the received data packet based on a predetermined amount of threshold level of distance, the threshold level of distance being a function of the finite amount of memory space of the data transmission device.

A fixture having a bottom plate, top plate and an expansion block interposed between the bottom plate and top plate. A workpiece is positioned between the expansion block and bottom plate.

A speaker system utilizes dipole speaker drivers in conjunction with monopole speaker drivers in a listening area to disperse a surround sound effect to a listener. The dipole speaker drivers are physically mounted on top of the front left and right speakers and are angled in a way that the surround information is delivered to the listener via wall / room reflections. By reflecting the sound off the walls, the system provides a delayed diffuse audio signal from the dipole speakers, enhancing the surround effect.
