Abstract: Laminated panels are made in a process whereby a starting foam formulation is processed through a mixhead, passed through a branched distribution system and dispensed through multiple outlets of the distribution system to produce a foam layer on a bottom facing layer. The foam layer is monitored for the presence of surface bubbles. When surface bubbles are observed, the backpressure in the mixhead is increased to reduce or eliminate the surface bubbles. An apparatus for performing the process includes an adjustment means at or upstream of a first branch point in the distribution system to increase or decrease the backpressure in the mixhead.

Abstract: In a method of scheduling transmission services over a high speed packet access communication link such as a HSDPA and/or a HSUPA link a list of queues is created for transmission services to be provided over the link. The queues, which include both Real Time and Non Real Time queues, are allotted respective service priorities based e.g. on a channel quality indicator and/or a Quality of Service indicator to produce an ordered list of queues based on the service priorities. The link resources needed for serving at least one set of queues having higher priorities in the ordered list are estimated and a check is made. If these resources are available, the set of queues having higher priorities in the ordered list are served. If the resources required are not available, at least one queue is removed from the ordered list of queues.

Abstract: A method of transmitting signals from a base station towards user terminals in a cellular communication system. The method includes generating diversity signals, wherein at least one of the diversity signals is subjected to a selectively variable RF phase shift. Specifically, a set of radio link quality indicators is determined at the base station, wherein each radio link quality indicator is representative of the quality of the radio link between the base station and a respective one of the user terminals. The set of radio link quality indicators is used to generate an aggregated radio quality indicator, which in turn is used to selectively vary the variable RF phase shift. For example, the phase shift may be selected, which optimizes the aggregated radio quality indicator.

Abstract: In a communication network, a node receives from user equipment information on the length of a queue of information units to be transmitted to the node from the user equipment. The information, for possible use by the node in scheduling transmission of these information units from the user equipment, is in the form of quantized queue length information indicative of a lower bound and an upper bound for the queue length. Transmission of information units from the user equipment to the node is detected at the node, and an improved estimate of the queue length is produced by correcting the lower bound and the upper bound via subtraction of the number of the detected information units transmitted from the user equipment to the node.
