| 20100133562 | High Brightness LED Utilizing a Roughened Active Layer and Conformal Cladding - A light emitting device and method for making the same are disclosed. The device includes an active layer disposed between first and second layers. The first layer has top and bottom surfaces. The top surface includes a first material of a first conductivity type, including a plurality of pits in the substantially planar surface. The active layer overlies the top surface of the first layer and conforms to the top surface, the active layer generating light characterized by a wavelength when holes and electrons recombine therein. The second layer includes a second material of a second conductivity type, the second layer overlying the active layer and conforming to the active layer. The device can be constructed on a substrate having a lattice constant sufficiently different from that of the first material to give rise to dislocations in the first layer that are used to form the pits. | 06-03-2010 |
| 20110121357 | LED with Improved Injection Efficiency - A light emitting device and method for making the same is disclosed. The light-emitting device includes an active layer sandwiched between a p-type semiconductor layer and an n-type semiconductor layer. The active layer emits light when holes from the p-type semiconductor layer combine with electrons from the n-type semiconductor layer therein. The active layer includes a number of sub-layers and has a plurality of pits in which the side surfaces of a plurality of the sub-layers are in contact with the p-type semiconductor material such that holes from the p-type semiconductor material are injected into those sub-layers through the exposed side surfaces without passing through another sub-layer. The pits can be formed by utilizing dislocations in the n-type semiconductor layer and etching the active layer using an etching atmosphere in the same chamber used to deposit the semiconductor layers without removing the partially fabricated device. | 05-26-2011 |

| 20090220668 | CLARIFIED TEA EXTRACT AND METHOD OF MAKING SAME - A method of making a clarified tea extract to reduce the cloudiness of a beverage containing the clarified tea extract by producing an aqueous tea extract that contains tea insolubles, adding a food-acceptable acid and a salt to the aqueous tea extract simultaneously and thereafter holding the aqueous tea extract with minimal agitation to produce a precipitate and clarifying the aqueous tea extract. Another method of making a clarified tea extract by adding a base to extraction water, contacting the base-containing extraction water with a tea source to produce an aqueous tea extract, adding a food-acceptable acid to the aqueous tea extract, and thereafter holding the aqueous tea extract with minimal agitation to produce a precipitate and clarifying the aqueous tea extract. | 09-03-2009 |
| 20090248622 | METHOD AND DEVICE FOR INDEXING RESOURCE CONTENT IN COMPUTER NETWORKS - A method and device index resource content in a computer network. The computer network includes at least a first computer as a search engine and at least a second computer as a resource content site where a resource content of a user is stored. A determination is made as to whether the resource content is linked to a user-defined indexing code. The user-defined indexing code is used to process the resource content to obtain a set of information describing the resource content. The user-defined indexing code is executed in response to determining that the resource content is linked to the user-defined indexing code. The set of information describing the resource content is obtained as an indexing result in response to the executing. | 10-01-2009 |

| 20080238857 | DISPLAY DEVICE AND METHOD FOR CONTROLLING BACKLIGHT MODULE OF THE DISPLAY DEVICE - A method for controlling a backlight module of a display device includes: generating an acceleration signal representing the magnitude of an acceleration of the display device; comparing the acceleration signal with a predetermined threshold to determine whether the acceleration signal is greater than the predetermined threshold; and changing a state of the backlight module if the acceleration signal is greater than the predetermined threshold. | 10-02-2008 |
| 20090043876 | METHOD FOR MANAGING DEVICES AND A MANAGEMENT ENTITY IN A USER NETWORK - The present invention relates to the communication field and discloses a method for managing devices in a user network and a user network management entity which handles combining and splitting operations in the user network more efficiently. In the technical solution provided by the present invention, the management entity of the user network obtains the information about the location of the managed PANs and/or stand-alone devices, and, based on the location information, checks existence of any PAN and/or stand-alone device that can be combined or split. If any such device exists, the management entity performs the combining or splitting operation according to the combining or splitting mode preset or selected by the user. In the process of combining or splitting a PAN or stand-alone device, the user can reserve the network registration information of some relevant devices as required, update the network registration information of other devices directly, and switch the service access points to ensure continuity of network services. | 02-12-2009 |
| 20090044258 | COMMUNICATION METHOD AND SERVICE IN PERSONAL AREA NETWORK - The present invention provides a communication method and device in personal area network, the method for communication between device in a PAN includes: a central device in the PAN receives from a first device in the PAN a communication request for communication with a second device in the PAN; the central device authenticates the first device and the second device; and a point-to-point connection is established between the first device and the second device. Since no access to the access network and the core network is needed during security authentication, thus reducing the signaling traffic of the access network and the core network. | 02-12-2009 |
| 20090129356 | METHOD, APPARATUS AND SYSTEM FOR INFORMATION TRANSMISSION - A method, an apparatus and a system for information transmission are provided. The method includes the following steps. A second user equipment receives update information issued by a wireless access point (AP). The second user equipment is located within a coverage area of the wireless AP. After detecting that the second user equipment has the update information, a first user equipment establishes a connection with the second user equipment and obtains the update information from the second user equipment. The first user equipment is located outside the coverage area of the wireless AP. In the present invention, the user equipment can update the information without additionally increasing the transmit powers of the wireless AP and the user equipments when located outside the coverage area of the wireless AP, and thus the interference to other equipments is minimized. | 05-21-2009 |
