Abstract: Techniques are described for load balancing subscriber sessions across tunnel termination devices. A network device is described, for example, that includes a tunneling module that load balances subscriber sessions across a plurality of tunnel termination devices based on weightings associated with the tunnel termination devices. The weightings may be assigned to the tunnel termination devices by a user, or may be calculated by the network device based on resource constraints associated with the tunnel termination devices. The network device may calculate the weightings, for example, based on a maximum number of subscriber sessions supported by each of the tunnel termination devices. As one example, the techniques may be applied to load balance Point-to-Point (PPP) subscriber sessions across L2TP Network Servers (LNSs).

Abstract: An arrangement (900), method and unit for AFC in a communication system (100) having: a frequency estimator (980) producing a decision-directed frequency estimate from a received signal; and an AFC loop receiving the decision-directed frequency estimate and performing therewith frequency control. The AFC process may use a CRC-decision directed frequency estimate as the final stage in a multi-stage AFC process (preceded by SCH- and midamble-derived frequency estimate stages), such that a verified received data sequence is used to re-construct a local copy of the ideal received data symbols expected at the output of a detector. This local copy is then correlated with the actual detector output and the results used to estimate the frequency error present on the received signal. The AFC process is inherent suited for discontinuous receive (DRX) applications. This provides the advantage of allowing required frequency correction accuracy to have minimal impact on the error rate of the received data in various channel configurations.

Abstract: Active control feedback between a base station and user equipment in a wireless communications network is achieved by allocating a first time slot within a frame for a UE to transmit a beacon signal to the base station, where the beacon signal is separate from data signals in the frame, allocating a second time slot within the frame for the base station to transmit a control signal in response to the beacon signal, and allocating other timeslots for the base station to operate in full duplex FDD mode. The control signal provides a basis upon which the UE adjusts a transmission parameter, such as power.

Abstract: This heat recovery device replaces the floor drain in a common residential shower. A large circular pan joins flush with the shower stall floor and funnels greywater into the drain piping. The circular pan contains the heat transfer device which preheats the incoming cold water and recovers approximately half of the heat that would otherwise be lost. The incoming cold water travels through a water turbine where it rotates an impeller. The impeller is magnetically coupled with a rotary whisk. The rotary motion continuously washes the draining greywater over a spiral warming coil. The spiral coil transfers the heat to the incoming fresh water as it travels to the shower's mixing valve.
