Title: circuito de controle e método para controlar a voltagem de saìda e/ou a corrente de saìda em uma fonte de alimentação de comutação controlada pelo lado primário
Inventor: BERGHEGGER RALF SCHROEDER GENAN
IPC: H02M1/14
Filed: 2006-11-17
Abstract: CIRCUITO DE CONTROLE E MéTODO PARA CONTROLAR A VOLTAGEM DE SAìDA E/OU A CORRENTE DE SAìDA EM UMA FONTE DE ALIMENTAçãO DE COMUTAçãO CONTROLADA PELO LADO PRIMáRIO. A presente invenção refere-se a um circuito para o controle da corrente e da voltagem em uma fonte de alimentação de comutação controlado do lado primário, a qual compreende um transformador com um enrolamento principal de lado primário e de lado secundário, em que os pulsos de energia são transmitidos do lado primário para o lado secundário. Além disso, uma chave do lado primário liga e desliga uma corrente primária através do enrolamento principal do lado primário. Um comparador de corrente primária determina o tempo de desligamento da chave, dependendo da corrente primária. Para reduzir a dependência de carga da voltagem de saída, a variável de controle é amplificada de modo variável por uma rede de retorno, e adicionalmente a variável de controle é reduzida, dependendo da carga de saída através de uma rede de correção. Para reduzir o ruído gerado pelas transmissões de pulso rico em energia em baixas freqüências e a ondulação da voltagem de saída, a variável de controle é retornada ao comparador de corrente primária, de uma maneira tal que a duração pela qual a corrente primária flui através do enrolamento principal do lado primário é reduzida de modo diferente. Para reduzir a susceptibilidade de talha ao determinar o tempo de ligação, Uma voltagem comparadora, que depende da variável de controle, é gerada como referência.

Title: Energy-efficient network protocol and node device for sensor networks
Inventor: YOON CHANG-JUNE
IPC: H04W52/02
Filed: 2006-02-24
Abstract: A method for changing routing responsibilities for a node in a tree-like wireless network 10 of nodes 200, 400 that exchange information between each other and ultimately with a main node 100, comprising: when communication with the upstream node is compromised, broadcasting a first message to inform downstream nodes that a repair is underway; and initiating a link to another node in a manner dependent on the power availability of the node. If attempts to join other nodes fail a second message, preferably a resign message, may be broadcast alerting downstream nodes to join at other nodes. Downstream nodes may receive messages from candidate upstream nodes indicating their routing responsibility which may be used to select a new upstream node. The available power may be compared with three thresholds. The comparison may result in: terminating all over-the-air transmissions; only transmitting local data; forwarding data to a node without joining that node.

Title: Real time correction of mispronunciation of a non-native speaker
Inventor: JENNINGS TERRY DON
IPC: G06F40/00
Filed: 2011-05-16
Abstract: A very common problem is when people speak a language other than the language which they are accustomed; syllables can be spoken for longer or shorter than the listener would regard as appropriate. An example of this can be observed when people who have a heavy Japanese accent speak English. Since Japanese words end with vowels, there is a tendency for native Japanese to add a vowel sound to the end of English words that should end with a consonant. Illustratively, native Japanese speakers often pronounce "orange" as "orenji." The inventions provides an automatic speech-correcting process that would not necessarily need to know that fruit is being discussed; the system would only need to know that the speaker is accustomed to Japanese, that the listener is accustomed to English, that "orenji" is not a word in English and that "orenji" is a typical Japanese mispronunciation of the English word "orange." The invention identifies one or more distinct speech events in received speech and using a knowledge base to determine an incorrect syllable duration caused by mispronunciation, adjusts the mispronunciation to one or more of lengthen, shorten, emphasize or deemphasize a misspoken syllable.
