Abstract: Protective devices, such as, for example, helmets, have one or more efficient, fluid-containing shock absorbers in place of protective devices' original shock absorbing material to minimize the overall weight of the protective devices. The more efficient, fluid-containing shock absorbers yield improved impact force attenuation but occupy substantially less volume and, consequently, less weight, than the original shock absorbing material.

Abstract: Data packets are received at a communication device that is coupled to a network node in a communication network, to a gateway router that is coupled to other network nodes in the communication network, and to a further communication network. For each received data packet, a determination is made as to whether the received data packet is to be routed toward a destination by the communication device instead of by the gateway router. The received data packet is routed toward the destination by the communication device based on determining that the received data packet is to be routed toward the destination by the communication device instead of by the gateway router. Otherwise, the received data packet is switched from the communication device to the gateway router to be routed by the gateway router toward the destination.
