摘要： A server of an elastic computing cloud system includes a block device driver apparatus and at least a block device service apparatus. The server implements a hot deployment for a storage service, such that an upgrade of the storage service may be performed without interrupting the storage service. The block device driver apparatus maintains a waiting queue and a pending queue for each storage service. In response to determining a storage service will perform an upgrade, the block device driver apparatus stops processing data write/read requests that are maintained in the pending queue for the service, and puts the data write/read requests that are currently processed in the pending queue back to the waiting queue for re-dispatching, thus realizing completion of processing the upgrade of the storage service in the elastic computing cloud system without interrupting the storage service.

摘要： The present disclosure describes techniques that may provide more accurate estimates of arterial oxygen saturation using pulse oximetry by switching between a wavelength spectrum of at least a first and a second light source so that the arterial oxygen saturation estimates at low (e.g., in the range below 75%), medium (e.g., greater than or equal to 75% and less than or equal to 84%), and high (e.g., greater than 84% range) arterial oxygen saturation values are more accurately calculated. In one embodiment, light emitted from a near 660 nm and a near 900 nm emitter pair may be used when the arterial oxygen saturation range is high. In another embodiment, light emitted from a near 730 nm and a near 900 nm emitter pair may be used when the arterial oxygen saturation range is low. In yet another embodiment, light emitted from both a near 660 nm-900 nm emitter pair and light emitted from a near 730 nm-900 nm emitter pair may be used when the arterial oxygen saturation range is in the middle range. Priming techniques may also be used to reduce or eliminate start up delays of certain oximetry system components.
摘要翻译：本公开描述了可以通过在至少第一和第二光源的波长光谱之间切换使得使用脉搏血氧饱和度更准确地估计动脉血氧饱和度的技术，使得动脉血氧饱和度估计为低（例如，在下面的范围内 75％），中等（例如，大于或等于75％且小于或等于84％）和高（例如，大于84％的范围）动脉血氧饱和度值被更准确地计算。在一个实施例中，当动脉血氧饱和度范围高时，可以使用从近660nm和近900nm发射体对发射的光。在另一个实施例中，当动脉血氧饱和度范围低时，可以使用从近730nm和近900nm发射体对发射的光。在另一个实施例中，当动脉血氧饱和度范围在中间范围时，可以使用从近660nm-900nm发射体对发射的光和从近730nm-900nm发射体对发射的光。引发技术也可用于减少或消除某些血氧饱和度系统组件的启动延迟。

摘要： The invention relates to compensating for the wavelength dependent loss (WDL) in a variable optical attenuator (VOA) system by using a chromatic dispersion wedge, which is inserted between the mirror and the lens. Different wavelength components, e.g. shorter blue and longer red wavelengths, are redirected at different angles by the chromatic dispersion wedge and now arrive at the output fiber at different positions. Thus the smaller mode field diameter (MFD) or mode spot size of the blue light, overlaps more of the core of the output fiber by being closer thereto and now has less insertion loss (IL) as compared to a VOA without WDL compensator.
摘要翻译：本发明涉及通过使用插入镜和透镜之间的色散楔来补偿可变光衰减器（VOA）系统中的波长相关损耗（WDL）。不同的波长分量，例如较短的蓝色和较长的红色波长通过色散楔形件以不同的角度重定向，现在在不同位置到达输出光纤。因此，与没有WDL补偿器的VOA相比，蓝光的较小的模场直径（MFD）或模式光斑尺寸通过更靠近输出光纤的核心而更多地与现在具有较小的插入损耗（IL）。
