A number of data relay devices, e.g. mobile telephones, (10, 20, 30, 40, 50, 60, 70, 80), are conveyed by vehicles and move relative to each other. They form a vehicular ad hoc wireless network (19, 29, 39, 49), etc in which data stored by a device (20) (either own-generated or relayed from another device (10) is transmitted either directly or by means of one or more other devices (30) to a network access point (90) which interfaces with a cellular network. When two devices (20, 30) come into proximity to each other, they use an opportunistic routing algorithm to determine a forwarding direction for the data. A retransmit timer is triggered on transmission of data, and messages which are unacknowledged at the expiry of the timer period are retransmitted. The timer period dynamically follows local congestion conditions and is recalculated at each transmission by the expression, timer minimum period/recent forwarding success(t). The current recent forwarding success at time t, RFS(t), is calculated from the RFS(t−1) calculated for the immediately preceding transmission and from the current forwarding success, CFS, by the expression RFS(t)=4/5 RFS(t−1)+1/5 CFS(t) where CFS is the square of the ratio of the available buffer space in the target device to the size of the payload in the source device.

A technique for a time division multiplex system in which access to shared broadcast communication media is granted on a demand basis. Particular connections are assigned slot times at the transmitter based on demand. However, no specific information regarding the assignment of time slots need be communicated to the receivers. The transmit side employs a forward error correction technique followed by multiplication by a cover sequence unique to each connection. All receivers listen to the broadcast transmission channel all of the time. The receiver assigned to each connection decodes the signals in such a manner that only the receiver with the correct cover sequence assigned to a particular connection will successfully decode the data associated with that connection. Data frames that fail the forward error correction process are discarded, and only those frames which are successfully decoded are passed up to a higher layer. The occurrence of an erroneously received frame is not necessarily always reported to the transmit side of the connection; only a packet level error indication is made. In this way, information containing time slot assignment need not be communicated between the transmitter and receiver, and yet data will be correctly received.

A network monitoring apparatus in a mobile communications network monitors, for a predetermined time, TCP packets in the network that tend to comprise end-user traffic using the high-speed data path but not the low-speed data path to provide monitored packet information. The network monitoring apparatus uses this monitored packet information to identify the fastest end user-experienced communication exchanges within the mobile communications network. By one approach, the network monitoring apparatus effectively filters out most or all of the end-user traffic that uses the low-speed data path when providing that monitored packet information. This can comprise, for example, tending to utilize data pertaining to TCP packets that correspond to higher traffic volume (and hence that are likely being conveyed via a high-speed data path) while also tending to discard data that pertains to TCP packets to that correspond to low traffic volume (and hence that are likely being conveyed via a low-speed data path).

An apparatus and method for containing plasma and forming a Field Reversed Configuration (FRC) magnetic topology are described in which plasma ions are contained magnetically in stable, non-adiabatic orbits in the FRC. Further, the electrons are contained electrostatically in a deep energy well, created by tuning an externally applied magnetic field. The simultaneous electrostatic confinement of electrons and magnetic confinement of ions avoids anomalous transport and facilitates classical containment of both electrons and ions. In this configuration, ions and electrons may have adequate density and temperature so that upon collisions ions are fused together by nuclear force, thus releasing fusion energy. Moreover, the fusion fuel plasmas that can be used with the present confinement system and method are not limited to neutronic fuels only, but also advantageously include advanced fuels.

A piezoceramic surface actuator comprising multilayer plates each having a plurality of piezoceramic plates separated from one another by in each case a positive or negative electrode. The positive and negative electrodes alternate and are constructed integrally with the piezoceramic plates, and have collector electrode surfaces for the positive and negative electrodes, which are connected to the associated positive or negative electrodes in a conducting manner and are arranged on two exterior sides of the surface actuator that are opposite from one another. The multilayer plates are plate-shaped and have a much greater width of the piezoceramic plates, defined by the distance between the opposite collector electrode surfaces, than the thickness of the multilayer plates. The collector electrode surface in each case contacts the positive or negative electrodes of the neighboring multilayer plates.
