    摘要: A server-assisted computational method for computing the RSA cryptography is delineated in this document. The method enables public-key functions on the resource-constrained devices, such as a mobile phone or a PDA, by leveraging the rich computing resources provided by the server-grade computers on the network. Public-key processing, which is computationally intensive, as commonly known, if loaded solely on the constrained device, would easily overwhelm the processor capacity and electrical power supply. The server-assisted method enables such device to drive a powerful server computer on the Internet to carry out the public-key number-crunching job for its sake. Some near-completion results are communicated back to the device. From that, the final public-key cryptograph is derived. Privacy and security are the utmost important considerations in public-key systems. The present invention ensures the privacy of the device by blinding the server of the secret message and the crypto keys of the device. The merit is that the client device is able to accomplish the public-key processing with the help of the server, but without compromising the private crypto keys and confidential message code to the server.

    摘要: On field ionization under ambient conditions is described and applied on both ionization and desorption of various chemicals and biochemical present on the surface of materials in solid, liquid or gas states. The Atmospheric Pressure Megavolt Electrostatic Field Ionization Desorption (APME-FID) method generates ions directly from the surface of samples connected to a high electrical voltage at megavolt conditions. Megavolt electrostatic potential is generated and gradually accumulated directly on the sample surface by a Van de Graaff generator without causing damage to the sample. Therefore, when coupled with mass spectrometric system, the APME-FID-MS method enables direct detection of analytes on the surface of samples in different sizes and diverse types.

    摘要: Systems, methods, and devices are provided for controlling a movable object using multiple sensors. In one aspect, a method for determining initialization information for a movable object comprises: detecting, with aid of one or more processors, that the movable object has started operating; receiving, at the one or more processors, inertial data from at least one inertial sensor carried by the movable object; receiving, at the one or more processors, image data from at least two image sensors carried by the movable object; and determining, with aid of the one or more processors, the initialization information for the movable object based on the inertial data and the image data, wherein the initialization information one or more of a position of the movable object, a velocity of the movable object, or an orientation of the movable object relative to a gravity direction when the movable object started operating.
