| 20110305934 | ELECTRONIC DEVICE WITH BATTERY COVER WATERPROOF STRUCTURE - An electronic device with a battery cover waterproof structure includes a body having a first end and a second end, a battery compartment disposed in the body, a waterproof gasket disposed in the battery compartment, and a battery cover coupled to the body. The waterproof gasket includes an oblique engage surface, and one end of the oblique engage surface near the first end is elevated higher than the other end of the oblique engage surface near the second end. The battery cover has an oblique rib arranged corresponding to in the oblique engage surface. One end of the oblique rib near the first end is elevated higher than the other end of the oblique rib near the second end. The oblique rib will interfere with the oblique engage surface for sealing the battery compartment when the battery cover is pushed towards one end of the battery compartment near the first end. | 12-15-2011 |

| 20100123902 | Method for Determining the Dynamic Range of Volume Holographic Memories - A method for measuring a saturated photorefractive index and a recording time constant to correct the precision includes measuring the diffraction efficiency as a function of time for both phase matching and phase mismatching. The saturated photorefractive index and the recording time constant are verified by substitution into a theoretical formula derived from the Coupled Wave Theory. Thus, the method allows a precise determination of the dynamic range of volume holographic memories and thus their storage capacities. The same procedure can also apply to photopolymers. | 05-20-2010 |
| 20100280142 | Shaped Information-Storage Material of Photopolymers and Methods for Making Same - A method for making shaped information-storage material of photo polymers includes mixing powdery azobisisobutyronitrile (AIBN) and powdery acenaphthenequinone (AQ) into liquid monomers of methyl methacrylate (MMA) and stirring a mixture of the AIBN, AQ, and MMA to form a solution. The azobisisobutyronitrile (AIBN) serves as a thermo polymerization initiator, and the acenaphthenequinone (AQ) serves as a photo polymerization initiator. The solution is filtered to remove the saturated photo polymerization initiator. Then, the filtered solution is poured into a shaping container and heated in the shaping container to make solid, shaped information-storage material of photo polymers. The shaping container is then opened to remove the shaped information-storage material of photo polymers. The shaped information-storage material of photo polymers includes two flat lateral sides. | 11-04-2010 |

| 20090107907 | DROPLET-BASED DIGITAL MICRODIALYSIS - The invention relates to a droplet-based digital microdialysis method that utilizes discrete perfusate droplets marched through a microchannel in an intermittent manner. The droplets sequentially reside on a microdialysis membrane that is in contact with the test fluid, e.g., fluid in an extracellular space. The droplets remain stationary at the membrane site for a period of time for rapid equilibration with the test fluid, and is then marched to an outlet port for processing. The invention further relates to microdialysis probes and methods based on the droplet-based digital microdialysis. | 04-30-2009 |

| 20090119265 | DISTRIBUTED MULTIMEDIA ACCESS SYSTEM AND METHOD - A distributed media access system and method. The method includes making each of a plurality nodes in a P2P network designate at least one nearest neighbors as a first node candidate and perform at least one random walk to obtain a second node candidate according to the peer list; calculating user preferences of the request node and user preferences of the first and second node candidates according to the first and second node candidates and the preference parameters corresponding to the first and second node candidates so as to obtain a plurality of similarity values; selecting the more similar candidate as buddies of user of the node according to the calculated similarity values; and establishing a buddy list according to the buddies of user and storing the buddy list such that the P2P network can quickly find buddies of the node through the buddy list. | 05-07-2009 |
| 20090268677 | NETWORK RESOURCE ALLOCATION SYSTEM AND METHOD OF THE SAME - A network resource allocation system and method of the same are provided according to the present invention. The system and method are applicable to a wireless mesh network, the method including: programming traffic of connections between routers; exchanging data between neighboring routers, thereby enabling the routers to perform dispersive network resource allocation according to the exchanged data; checking a local time window and a global time window for expiration by the router; and, under the condition of local performance deterioration or local traffic variation, activating a local routing adjustment mechanism by the router, wherein, if global performance deterioration currently exists, then activating a global optimization mechanism by a central controller, and, if not, then resetting the global time window. Accordingly, the present invention is capable of perceiving the traffic status of each connection between routers, thereby efficiently directing traffic to various channels and wireless transceivers. | 10-29-2009 |
