    摘要: Described is a system for automatic digital photo orientation detection. We leverage online public photos with great content variation to extract effective features with layout information. Classification proceeds using an approximate nearest neighbors approach which scales well to massive training sets, hardly compromising efficiency. We have tested the method successfully on the largest data set to date of nearly 30,000 Flickr photos as well as both difficult and typical consumer usage scenarios. Though limited data are available for comparison across different systems, the proposed system significantly outperforms a state of the art system on a common data set.

    摘要: An axial flow impeller includes a hub, at least three base blades, and a cover blade detachably mounted to each base blade. When the impeller is applied in a medium environment having a high density and viscosity, the impeller will meet the requirement only by virtue of the base blade with the cover blade being removed. When the impeller is applied in a medium environment having low density and viscosity, the cover blade can be mounted in the front and/or rear of the base blade in order to improve the efficiency of the impeller. In this case, the consumption of electrical power can be reduced significantly while producing an equivalent propulsive force, thereby being advantageous for energy conservation. Therefore, the impeller can be adaptable to different medium environments and efficiency requirements, and thus can have good adaptability, need minimal investment cost and can be convenient to use.

    摘要: A medical system includes one or more medical body area network (MBAN) systems. Each MBAN system includes one or more MBAN devices which acquire and communicate patient data with a hub device via short-range wireless communication. The communication of the patient data via the short-range wireless communication is within a predefined spectrum. The hub device receives patient data communicated from the one or more MBAN devices and communicates with a central monitoring station via a longer range communication. A MBAN channelization scheme defines one or more overlapping channels in the predefined spectrum and a MAC parameter dynamically enables or disables access to each defined channel. A channel regulator manages the MBAN utilization of the predefined spectrum by setting the MAC parameter to dynamically enable/disable the one or more predefined MBAN channels within the predefined spectrum.
