    • The present invention provides a method for the Medium Access Control (MAC) layer in IEEE 802.11e Enhanced Distributed Channel Access (EDCA) to improve its performance. Contention parameters are used in EDCA to provide Quality of Service (QoS). However, these parameters are only good for low number of senders and there is a need to adjust the parameters dynamically when the network conditions changes. The present invention enhances the throughput for each priority class and makes it stable and almost independent to the total number of senders in the network. Hence, the need of adapting the contention parameters is not longer required. The present invention also provides capacity for a priority class that is directly proportional to the contention parameters used.
    • 本发明提供了一种用于IEEE 802.11e增强分布式信道接入(EDCA)中的媒体接入控制(MAC)层的方法,以提高其性能。 EDCA中使用争用参数来提供服务质量(QoS)。 然而,这些参数只对低数量的发送者有好处,并且需要在网络条件变化时动态地调整参数。 本发明增强了每个优先级的吞吐量,使其稳定并且几乎独立于网络中的发送者总数。 因此,不再需要适应争用参数。 本发明还提供与所使用的竞争参数成正比的优先级的容量。

    • A passive optical component directs first electromagnetic radiation incident on the component in a first direction and second electromagnetic radiation incident on the component in a second direction to a mutual direction. The optical component comprises an interacting surface which is arranged to interact with said first and second electromagnetic radiation. The interacting surface comprises first portions, each having a surface extending in a third direction, which is essentially perpendicular to the mutual direction, and second portions, each having a surface extending in a fourth direction. The optical component reflects essentially all the first electromagnetic radiation and transmits at least a significant portion of the second electromagnetic radiation for directing the first and the second electromagnetic radiation to a mutual direction. An optical system and a method using the passive optical component are also shown.

    • A method and a process are disclosed for optimizing an electrostatically dosed dry powder inhaler (EDPI) for utilization of a prepared pre-metered electro-dose consisting of a electro-powder. An arrangement is set-up for measuring parameters affecting a systemic delivery or local lung delivery of a pre-metered electro-dose from and DPI including analysis of dose de-agglomeration, particle size distribution as well as dose-to-dose variation together with pressures times and flows. A dry powder inhaler, DPI, is adjusted for a systemic or a local lung setting with respect to activation pressure and closing pressure having a DPI with a 20 to 60 liters/minute inhalation air flow for systemic delivery setting and 20 to 80 liters/minute for a local lung setting. Furthermore the de-agglomeration power is adjusted between 0.1 and 6 watts to be used in the DPI by optimizing the pressure drop and inhalation flow rate by changes to the mouthpiece and/or the device member and their relation to each other. The DPI activation pressure is further adjusted to a value between 0.5 and 4 kPa and closing pressure between 0.5 and 4 kPa to eliminate the low power at the start and end of the inhalation. The method and process then verify that the DPI meets the specifications set regarding de-agglomeration of power and opening and closing pressures together with timings within the DPI active time. Furthermore is verified that de-agglomeration difference, expressed in percent using an expression 100[1-de-agglomeration(Q1 kPa)/de-agglomeration(Q)], is not more than 50%. Finally if the DPI is not approved as an EDPI the tested DPI and/or electro-dose is further adjusted to check if the DPI can meet the specifications of an EDPI.
