Title: Estimativa de canal para sistemas de comunicação ofdm
Inventor: KRISHNAN RANGANATHAN
IPC: H04B17/00
Filed: 2003-10-29
Abstract: "ESTIMATIVA DE CANAL PARA SISTEMAS DE COMUNICAçãO OFDM". Trata-se de técnicas para estimar a resposta de frequência de um canal sem fio em um sistema OFDM. Em um método, uma estimativa inicial da resposta de frequência do canal sem fio é obtida para um primeiro grupo de sub-bandas com base na transmissão de piloto recebida por meio das sub-bandas do primeiro grupo. Uma estimativa da resposta de impulso do canal sem fio é em seguida obtida com base na estimativa de resposta de frequência inicial. Uma estimativa aperfeiçoada da resposta de frequencia do canal sem fio é então obtida para um segundo grupo de sub-bandas com base na estimativa de resposta de impulso. os primeiro e segundo grupos podem incluir, cada um, todas ou apenas um subconjunto das sub-bandas utilizáveis. A multiplexação de sub-bandas pode ser utilizada para permitir transmissões de piloto simultâneas de vários terminais em seus grupos afins de sub-bandas.

Abstract: With known carrier materials in bioreactors there is frequently blockage of the reactor with microorganisms or organic compounds. The new carrier material intends to make it possible for microorganisms or animal cells to be immobilised in a high concentration without blockage of the bioreactor occurring. 
<??>This object is achieved by using as carrier material beads which, on the one hand, consist of an open-pore inorganic sintered body which has pores which pass through the inside and are open to the outside and in which microorganisms and animal cells are able to be immobilised and grow and, on the other hand, have a density and a diameter such that, in a preset fluidised bed flow, the shear forces of the beads suffice to shear off the microorganisms or animal cells growing out of the interior of the beads and/or located on the surface. 
<??>The invention makes it possible to combine the advantages of the fixed bed reactor with the advantages of the fluidised bed reactor, and to avoid the disadvantages of both processes. The carrier material is not confined to the digestion of domestic and industrial effluents, it can also be employed for the biotechnological obtaining of essential dietary substances and pharmacological substances and of fermentation products.

Abstract: The improved wellhead structure of the present invention includes a casing or tubing string (10) which is sealed to the housing (18) without the aid of elastomeric seals and an internal bushing (14) to assist in providing the tight gripping and sealing engagement between the string and the housing. The structure provides a substantial inner diameter which is unrestricted unless landing shoulder is included in the structure. Also, the internal bushing used with the cold forging of the string into the housing recess improves the gripping and sealing engagement therebetween. In one form the bushing (14) includes a series of external projections which alternate with the gripping and sealing projections within the housing recess and in another form includes a resilient annulus (42) between the interior of the bushing and the string to ensure the uniform application of pressure against the interior of the string. In still another form an internal landing shoulder is cold forged into tight engagement with the interior of the housing which allows full bore operations to be carried through the housing until the landing shoulder is to be installed. Also provided is a wellhead structure with a tieback structure in which the upper end of the casing is cold forged into the interior of a hanger while the casing is supported on slips.

Trata-se de um regulador de janela acionado por motor para uso com uma janela de correr de forma horizontal (18) instalada na abertura do vidro traseiro de uma cabine de um caminhão pick-up. A janela de correr é movida entre uma posição fechada, onde ela preenche um espaço entre duas janelas montadas externas (16, 17) e uma posição aberta, onde elas desliza para se sobrepor sobre uma das janelas fixas deixando a abertura aberta. A janela de correr é atida por um par de cabos de ativação linear (24) cada dos quais está ligado à janela de correr em uma primeira extremidade e a um tambor de acionamento do cabo acionado por motor (70) em uma segunda extremidade. Os cabos de ativação linear estendem-se para longe da janelas de correr em direções opostas paralelas à direção de movimento corrediço e enrolado ao redor do tambor de acionamento do cabo e direções opostas, de modo que a rotação do tambor de acionamento do cabo em uma direção coloca um primeiro cabo em tensão para puxar a janela de correr em direção à posição aberta e a rotação do tambor de acionamento do cabo na direção oposta tensiona o cabo para puxar a janela de correr em direção; posição fechada. A configuração de acionamento de cabo de puxar/puxar resulta na habilidade de utilizar menos tolerância mais próximas e por conseq³ência cabos de acionamento menos onerosos, bem como um motor que seja muito menor, menos onerosos e consuma menos energia.
