Next, the content provider uses the public address to identify a local caching server (LCS) on a local area network (LAN) to which the electronic device is connected and uses the account identifier to determine that an account associated with the LCS is associated with a group of accounts with which an account for the electronic device is also associated. The content provider then provides a local address of the LCS to the electronic device, which uses the local address to obtain the content from the LCS via the LAN without accessing a content delivery network outside the LAN. |

Delivering customized content to mobile devices
The illustrative embodiment of the present invention provides a platform that enables a content developer to distribute uniform content to multiple types of requesting mobile devices. By authoring content in a generic markup language and using the technologies included in the Mobile Content Framework (MCF), the content developer is able to provide content to multiple types devices without providing different versions of the content. The content may be authored originally in the generic markup language or translated from other languages into the generic markup language by the MCF. The MCF exploits the capabilities and accommodates the limitations of different types of wireless devices by converting generic markup language content to device-specific content. The MCF interacts with device registries holding records of the device attributes in order to provide the device-specific content. The MCF handles these issues for current mobile devices while also being extensible for future mobile devices. |

Redirecting from a cloud service to a third party website to save costs without sacrificing security
Techniques are provided for receiving a request from a client proxy device to access a file on a server. The file is associated with a uniform resource locator (URL). In response to receiving the request, the server proxy device evaluates the request for presence of information that indicates that the client proxy device is able to obtain redirect instructions to access the file. When the evaluating indicates that the request includes the information, the server proxy device requests and receives identifier information associated with the URL from the server. The server proxy device retrieves from a database stored identifier information associated with the URL to compare it to the stored identifier information associated with the URL. When there is a match, the redirect instructions are sent to the client proxy device instructing the client proxy device to retrieve the file directly from the server. |

Platform-as-a-service with proxy-controlled request routing
When a user sends a request to access an asset or resource, for example a program code file or a media file, the access request can be processed by a proxy device. The proxy can use directory information obtained from a directory, for example a company-wide Lightweight Directory Access Protocol (LDAP) directory, to determine whether or not the request is from an authorized network user listed in the directory. The proxy can use management information obtained from another database to determine roles, subordinate assignment information, and access authorization information associated with the requesting user. The proxy can conditionally route the request to a resource host based on the directory information and the management information. The proxy can also transform a resource returned in response to the request by using pipeline language parameters included in a URL associated with the access request. |

Visual feedback for process control in RTP chambers
Embodiments of the present disclosure generally relate to methods and apparatus for visual lamp failure detection in a processing chamber, such as an RTP chamber. Visual feedback is facilitated through the use of a wide-angle lens positioned to view lamps within the process chamber. The wide-angle lens is positioned within a probe and secured using a spring in order to withstand high temperature processing. A camera coupled to the lens is adapted to capture an image of the lamps within the process chamber. The captured image of the lamps is then compared to a reference image to determine if the lamps are functioning as desired. |

Method of atomic layer etching using functional group-containing fluorocarbon
A method of atomic layer etching (ALE) uses a cycle including: continuously providing a noble gas; providing a pulse of an etchant gas to the reaction space to chemisorb the etchant gas in an unexcited state in a self-limiting manner on a surface of a substrate in the reaction space; and providing a pulse of a reactive species of a noble gas in the reaction space to contact the etchant gas-chemisorbed surface of the substrate with the reactive species so that the layer on the substrate is etched. The etchant gas is a fluorocarbon gas containing a functional group with a polarity. |

System, method and apparatus for plasma etch having independent control of ion generation and dissociation of process gas
A method of etching a wafer includes injecting a source gas mixture into a process chamber. The injecting includes injecting the source gas into multiple hollow cathode cavities in a top electrode, generating plasma in each of the cavities, and outputting the plasma from corresponding outlets of the cavities into a wafer processing region in the chamber, where the processing region is located between the outlets and a surface to be etched. An etchant gas mixture is injected into the processing region through injection ports in the top electrode such that the etchant gas mixes with the plasma output from the outlets. The etchant gas is prevented from flowing into the outlets of the cavities by the plasma flowing from the outlets. Mixing the etchant gas and the output from the cavities generates a desired chemical species in the processing region and thereby enables the surface to be etched. |

Use of surfactants to control island size and density
Methods of controlling island size and density on an OMVPE growth film may comprise adding a surfactant at a critical concentration level, allowing a growth phase for a first period of time, and ending the growth phase when desired island size and density are achieved. For example, the island size and density of an OMVPE grown InGaN thin film may be controlled by adding an antimony surfactant at a critical concentration level. |
