    • An optical mode noise averaging device including a multimode optical fiber and means for averaging a modal noise induced signal level variation of light propagating within the multimode optical fiber. The device may average modal noise induced signal level variations by cyclically varying an index of refraction of the multimode optical fiber over a select period of time, scrambling a light distribution within the multimode optical fiber, or both. The index of refraction of the multimode optical fiber may be cyclically varied by cyclically varying the temperature of the multimode optical fiber. Alternatively, the index for refraction may be varied or the light distribution within the multimode optical fiber may be scrambled by cyclically manipulating the multimode optical fiber.
    • 一种包括多模光纤的光模式噪声平均装置和用于平均在多模光纤内传播的光的模态噪声感应信号电平变化的装置。 该器件可以通过在选择的时间周期周期性地改变多模光纤的折射率,扰乱多模光纤内的光分布,或两者来均衡模态噪声感应信号电平变化。 多模光纤的折射率可以通过周期性地改变多模光纤的温度来循环地变化。 或者,可以改变折射率,或者通过循环地操作多模光纤可以扰乱多模光纤内的光分布。

    • Various embodiments relate to a dose unit for a dry powder inhaler including: a dose carrier including a plurality of pockets each adapted to contain a dose of medication powder suitable for inhalation, the pockets being sequentially arranged such that the content of the pockets can be sequentially exposed to a flow of air for successive inhalations and a plurality of medication powder doses arranged in the pockets of the dose carrier. The doses are regularly distributed in the pockets according to a sequence of identical groups, each group including at least one blank pocket and one pocket containing a dose of medication powder. Various embodiments also relate to a pack including one such dose unit and one further dose unit with all pockets containing a medication powder. Various embodiments further relate to a dry powder inhaler including such a pack of dose units.

    • Rotary valve system for controlling communication with a port in an internal combustion engine which, in one disclosed embodiment, has a crankshaft, compression and expansion pistons connected to the crankshaft for reciprocating movement within compression and expansion chambers, a combustion chamber in which air from the compression chamber is combined with fuel and burned to produce an increased gas volume. The valve system has an outer valve member which is rotatively mounted in a bore and has an opening which moves into and out of communication with the port as the outer valve member rotates, an inner valve member rotatably mounted within the outer valve member with an opening at least partly overlapping the opening in the outer valve member, a flange extending along one edge of the opening in the inner valve member and through the opening in the outer valve member for sealing engagement with the wall of the bore, and means for effecting rotation of the valve members to change the degree of overlap between the openings and thereby control the timing and duration of communication between the openings and the port.
