| 20100210225 | MODULAR SOLID-STATE MILLIMETER WAVE (MMW) RF POWER SOURCE - A modular solid-state MMW power source based on a topology of the lens array amplifier provides both the flexibility to scale output power and effective thermal management. The modular power source includes a single submodule that uses one or more power dividers and one or more solid-state amplification stages to divide and amplify an RF input signal into R amplified RF signals. The submodule is mounted (suitably in the X-Y plane) on the surface of a heat sink, suitably coupled to a cold backplane, to remove heat. R 1:N low loss power dividers route the amplified RF signals to R*N radiating elements. Each of the 1:N power dividers suitably reside in the X-Z plane and are stacked in the Y direction to provide a planar output of the R*N radiating elements in the Y-Z plane. Placement of the amplifier chips on the single submodule decouples the number of amplifier chips, hence output power, from the number of radiating elements. Placement of the amplifier chips away from the radiating face provides a short path with large thermal cross-section through the heat sink to the backplane to remove heat. The topology can produce high output power combined with a high antenna gain to produce large power-aperture products previously only achievable with a Gyrotron. As amplifier chips become more powerful, the topology can be adapted to use fewer chips. | 08-19-2010 |

| 20100161328 | Utterance Processing For Network-Based Speech Recognition Utilizing A Client-Side Cache - Embodiments are provided for utilizing a client-side cache for utterance processing to facilitate network based speech recognition. An utterance comprising a query is received in a client computing device. The query is sent from the client to a network server for results processing. The utterance is processed to determine a speech profile. A cache lookup is performed based on the speech profile to determine whether results data for the query is stored in the cache. If the results data is stored in the cache, then a query is sent to cancel the results processing on the network server and the cached results data is displayed on the client computing device. | 06-24-2010 |
| 20100185447 | Markup language-based selection and utilization of recognizers for utterance processing - Embodiments are provided for selecting and utilizing multiple recognizers to process an utterance based on a markup language document. The markup language document and an utterance are received in a computing device. One or more recognizers are selected from among the multiple recognizers for returning a results set for the utterance based on markup language in the markup language document. The results set is received from the one or more selected recognizers in a format determined by a processing method specified in the markup language document. An event is then executed on the computing device in response to receiving the results set. | 07-22-2010 |

| 20110164533 | Methods and systems using PLD-based network communication protocols - Methods and systems for a PLD-based network update transport (PNUT) protocol that utilizes UDP and other protocols for transmitting update or other commands or information over a packet-based or IP network. PNUT is a hardware-based network communication protocol that does not require the full TCP/IP stack and may be utilized for exchanging commands and information with such PLD-based and other devices. Protocols may include a set of core commands and a set of custom commands. Logic components within the PLD-based devices may consist of a command dispatcher, a transmitter/controller, a MAC receiver, a MAC transmitter, a packet parser, a packet generator, and core receiving and transmitting commands. The present invention may be implemented without requiring CPU cores, special controllers, stringent timings, or operating systems as compared with conventional network protocols. Various methods for exchanging and updating PNUT commands are disclosed. The methods and systems of the present invention may be utilized to provide other functions, such as filtering, logging, polling, testing, debugging, and monitoring, and may be implemented between a server and a PLD-based device or solely between PLD-based devices. | 07-07-2011 |
| 20110197273 | Real time firewall/data protection systems and methods - Methods and systems for firewall/data protection that filters data packets in real time and without packet buffering are disclosed. A data packet filtering hub, which may be implemented as part of a switch or router, receives a packet on one link, reshapes the electrical signal, and transmits it to one or more other links. During this process, a number of filters checks are performed in parallel, resulting in a decision about whether each packet should or should not be invalidated by the time that the last bit is transmitted. To execute this task, the filtering hub performs rules-based filtering on several levels simultaneously, preferably with a programmable logic or other hardware device. Various methods for packet filtering in real time and without buffering with programmable logic are disclosed. The system may include constituent elements of a stateful packet filtering hub, such as microprocessors, controllers, and integrated circuits. The system may be reset, enabled, disabled, configured, and/or reconfigured with toggles or other physical switches. Audio and visual feedback may be provided regarding the operation and status of the system. | 08-11-2011 |

| 20090256861 | Device and Method for Managing the Orientation of Information Being Displayed on the Screen of a Device - A hand-held device and method for managing the orientation of information being displayed on the screen of a hand-held device is provided for devices having a two part slidable housing including a first housing and a second housing where the two housings are adapted to slide separately in multiple directions relative to one another along a corresponding path substantially parallel to a front facing of the device between an opened position and a closed position. The method takes into account a detected use mode, such as whether the device is engaged in a voice call communication, and a detected device configuration to determine the orientation of the information to be displayed on the device screen. When the first housing is slid relative to the second housing between a closed position and an opened position in a first direction, the information is displayed having a portrait orientation. The information is displayed having a landscape orientation, when the first housing is slid relative to the second housing between a closed position and an opened position in a second direction. When the hand-held device is in a voice call and the first housing is slid relative to the second housing between an opened position and a closed position, the information is displayed having a portrait orientation. When the hand-held device is not in a voice call and the first housing is slid relative to the second housing between an opened position and a closed position, the orientation of the information being displayed is not changed. | 10-15-2009 |
