20100132488	FLOW CYTOMETRIC APPARATUS AND METHOD - Various embodiments disclose a flow cytometric apparatus comprising a flow chamber to be passed through by a sample in a row in sequence, a sample storage means for metering and storing the sample, a sample syringe for driving the sample into the flow chamber, a syringe-type injection-suction device comprising a sheath liquid syringe and a liquid-path switching means connected with it, and a control unit for controlling the operations of the sample syringe and the syringe-type the injection-suction means. In a sample charging stage, the injection-suction means feeds the sample into the sample storage means so that the sample is temporarily stored in it in a ready-to-use state, and in a sheath-liquid injection stage, the injection-suction means feeds the sheath liquid into the flow chamber to form a sheath flow. A flow cytometric method performed by the flow cytometric apparatus is also disclosed.	06-03-2010

20090235920	Light tracking sensor and sunlight tracking system thereof - A light tracking sensor and a sunlight tracking system including the same, the light tracking sensor comprises two or more light tunnel devices. One end of the respective light tunnel devices form a common single-point micro-hole acting as an input port for directional light, the other ends of the light tunnel devices act as output ports for directional light and is provided with light-sensing units respectively. A sunlight tracking system is constituted of said light tracking sensor, a differential processing unit, an A/D converting unit, a microprocessor unit, a driving unit and an executive unit driven by the output end of the driving unit. Since one ends of the light tunnel devices form a common single-point micro-hole and the surface around the micro-hole is a curved surface, the sunlight tracking system, compared with the prior art, has a simpler structure, and a higher integration; Meanwhile, when in combination with certain software, a fast, accurate sunlight racking can be achieved, and its tracking precision is less influenced by the outdoor environment.	09-24-2009

20090307777	METHOD AND DEVICE FOR PREDICTING NETWORK ATTACK ACTION - A method for predicting a network attack action, including: monitoring a network status parameter and obtaining information of an attack action according to a change of the network status parameter; selecting a subsequent attack action which has a most possibility to happen from a plurality of subsequent attack actions of the attack action according to a correspondence between the attack action and the plurality of subsequent attack actions, the subsequent attack action which has the most possibility to happen being a subsequent attack action with a largest occurrence number among the subsequent attack actions corresponding to the attack action; and outputting the subsequent attack action which has the most possibility to happen as a predicted network attack action. A device for predicting a network attack action including an attack action management unit is also provided. The present invention describes the attack action procedure and the relation among attack actions during the attack action procedure and provides a network pre-warning method for determining which action is to be taken.	12-10-2009
