摘要： A wood material drying plant including a heater for generating a hot drying gas, a rotary dryer for bringing the hot drying gas into contact with the wood material to be dried, a wood particle separating unit being operative for separating entrained wood particles from the spent drying gas, and a gas cleaning system for removing pollutants from the spent drying gas. The wood material drying plant is provided with a heating gas duct which is operative for forwarding a gas portion to a mixing position located between the rotating drum of the rotary dryer and the wood particle separating unit, said gas portion having a higher temperature than the spent drying gas, and for mixing said gas portion with said spent drying gas, such that the temperature of the spent drying gas is increased.

摘要： A method and apparatus for predicting channel estimates for non-received signal frequencies provides knowledge of propagation channel characteristics for non-received frequencies. One embodiment predicts uplink (or downlink) channel estimates based on measured downlink (or uplink) channel estimates, which is advantageous in systems having different uplink and downlink frequencies. Another embodiment predicts channel responses for non-received OFDM sub carrier frequencies based on measuring channel responses for received OFDM sub carrier frequencies. Such processing may comprise, for example, measuring channel responses for received OFDM pilot sub carriers, predicting channel responses at frequency intervals corresponding to pilot sub carrier spacing, and interpolating between those values to predict channel responses at data sub carrier frequencies.

摘要： This invention relates to a manufacturing method for interconnecting at least a first and a second body part of a sheet material to form a part of a vehicle body. The method comprising the steps of arranging the first and second body parts so that they essentially overlap and abut each other in an overlapping area, and exposing a welding zone of the overlapping area to a hybrid welding process in order to interconnect said first and second body parts in said overlapping area. The hybrid welding process comprises at least a first resistance seam welding step and a subsequent laser welding step. An apparatus for performing this manufacturing method is also disclosed.
