20090059354 | OPTICAL AMPLIFIER TRANSIENT CONTROL WITH GAIN ERROR LIMITS - Optical amplifier transient control methods and apparatus which limit the extent of cumulative transient gain errors in the rapid control of multiple optical amplifiers in a communication system. In an exemplary embodiment, if the input power to an optical amplifier drops below a predetermined threshold, the gain of the amplifier is set to clamp the output power of the amplifier to its initial level less the threshold, thereby preventing the continuous growth of gain error. This is based on the assumption that once the input power goes below the threshold, it should no longer go above the threshold until the transient condition is corrected. The present invention can operate to handle down- as well as up-transient events and is not amplifier technology dependent. | 03-05-2009 |
20090214204 | Optical network monitoring using amplifier modeling - Example embodiments include a method for monitoring an optical network. The method provides received network data to a network model, which determines if there is an inconsistency within the optical network. The network models include a statistical model and a detailed-physical model, both of which model amplifier physics. | 08-27-2009 |
20090247295 | Network-Based Methods and Apparatus for Rendering Images to an End User - Network-based methods and apparatus are provided for rendering images to an end user. Video images are generated by receiving user input from a remote user; rendering the video in real-time in response to the user input; and transmitting the video to the user. The video may comprise, for example, video game images and the video game is executed by a centralized tendering engine. The rendering can be performed by a rendering engine that is remote from the user. The user input can be obtained, for example, from one or more of a game pad, steering wheel and joystick that is local to the user. A service provider can transmit the video to the user using a pre-existing media distribution connection between the service provider and the user | 10-01-2009 |
20100050042 | DELIVERY METHOD FOR INTERNET PROTOCOL TELEVISION (IPTV) - A delivery method for IPTV which combines forward error correction (FEC) with retransmission techniques for handling packet loss and/or corruption. Packet loss or corruption of popular channels is handled through the use of FEC while packet loss of less popular channels is handled by retransmission. | 02-25-2010 |
20100102936 | REMOTELY CONTROLLABLE POWER SWITCH OF AN APPLIANCE AND METHODS OF EMPLOYING THE SAME - A remotely controllable power switch of an appliance and a method of employing a remotely controllable power switch of an appliance to control the overall load that an electric power distribution network bears. The method may include a method of employing a remotely controllable power switch of an appliance to compute the rate that a particular customer pays for electric power. In one embodiment, the remotely controllable power switch of an appliance includes: (1) a switching device coupled between an input and an output of the remotely controllable power switch of an appliance and (2) communication circuitry coupled to the switching device, addressable only by class and configured to receive a turn-off signal and turn off the switching device in response thereto. | 04-29-2010 |
20100276995 | Security for wireless transfer of electrical power - A security mechanism is provided for wireless power transfer applications including resonant source and device objects, wherein tuned resonance between source and device objects is necessary for efficient power transfer. Tuning parameters associated with the source object are periodically adjusted so as to require corresponding changes in tuning parameter(s) of the device object to maintain tuned resonance. The tuning parameters are communicated to authorized users such that only authorized users capable of matching the changes made by the transmitter would be capable of receiving power. Unauthorized users that are unaware of the transmit tuning parameters will be rendered unable to maintain tuned resonance and thus unable to receive power. | 11-04-2010 |
20110084664 | METHOD AND APPARATUS OF STORED ENERGY MANAGEMENT IN BATTERY POWERED VEHICLES - A secondary battery and charging system are provided within an electric car or other electric drive vehicle. The secondary battery may, e.g., be owned by the electric utility. The battery is removable and can be charged and discharged independently of the primary car battery system. The utility can use the secondary battery to implement vehicle-to-grid functionality. | 04-14-2011 |
20120137201 | ENABLING PREDICTIVE WEB BROWSING - A system and method for determining and displaying, in a predictive manner, relevant “next clicks” based upon historical web-usage patterns of previous visitors (the browsing user and/or other users) to referring web pages. In one embodiment, identification of one or more links selected by previous visitors on a plurality of referring web pages is stored in a database. When the browsing user initiates a request to view a referring web page for which one or more links exist in the database, the appearance of those links on the referring web page is altered to suggest those links to the browsing user. Thus, the browsing user is given suggestions as to the most probable path (based upon his/her own history and/or the history of others) through each referring web page for which one or more links are stored in the database, thereby streamlining the browsing process. | 05-31-2012 |
20130090914 | AUTOMATED WORD SUBSTITUTION FOR CONTEXTUAL LANGUAGE LEARNING - A contextual language learning capability is disclosed. The contextual language learning capability is configured to enable an end user to use knowledge of a first language to learn a second language. The contextual language learning capability is configured to modify source content (in which content is provided in the first language) to form modified content (including a combination of content in the first language and content in the second language). The source content is processed to replace at least a portion of the content provided in the first language with corresponding content provided in the second language, thereby producing the modified content. The modified content is presented to the end user for use in learning the second language. The replacement of a subset of the source content in the first language with corresponding content in the second language gives context to the content in the second language, thereby giving the end user an understandable context for the content provided in the second language. This increases the likelihood that the end user will be able to understand and, thus, learn, the second language. | 04-11-2013 |
20140143882 | SYSTEMS AND METHODS FOR PRESERVING PRIVACY FOR WEB APPLICATIONS - A system and method for preserving privacy includes selecting a plurality of lexicons and executing a plurality of random operations through at least one web application using the plurality of lexicons. The system and method models the plurality of random operations based on typical usage to mask actual operations or searches executed by a user. | 05-22-2014 |
