Title: undice de modulação programável para transponder
Inventor: YONES DALE LEE
IPC: G08C17/00
Filed: 1999-12-15
Abstract: "ìNDICE DE MODULAçãO PROGRAMáVEL PARA TRANSPONDER". Trata-se de um índice de modulação variável para um transponder (102, 200, 400) capaz de medir um ou mais parâmetros (como, por exemplo, temperatura, pressão) em um objeto (como, por exemplo, um pneu (104)) e transmitir uma corrente de dados (figuras 3C, 4B) a uma leitora/interrogador externo (106). O transponder funciona tipicamente em um modo passivo, obtendo sua energia (Vxx, Vcc, Vdd) de um sinal de interrogação de RF recebido por um sistema de antena (210, 410, 710), mas pode funcionar também em um modo ativo energizado por bateria. O transponder inclui uma memória (238, 438) para armazenar medições, dados de calibração, ajustes de nivelamento programáveis (436b), ID do transponder e semelhantes. A transmissão da corrente de dados é de preferência efetuada por modulação PSK (700) do sinal de RF recebido, em que a magnitude de modulação (índice) varia de maneira programável em etapas binárias de acordo com os ajustes de nivelamento programados, e varia dinamicamente de acordo com o nível de energia de entrada de modo a se otimizar a transmissão. O sinal transmitido é limpo para que se remova o ruído dele pela sincronização de um sinal de relógio com o sinal da corrente de dados.

Inventor: BALIARDA CARLES PUENTE
IPC: H01Q5/10
Filed: 1999-09-20
Abstract: Antennae in which the corresponding radiative element contains at least one multilevel structure formed by a set of similar geometric elements (polygons or polyhedrons) electromagnetically coupled and grouped such that in the structure of the antenna can be identified each of the basic component elements. The design is such that it provides two important advantages: the antenna may operate simultaneously in several frequencies, and/or its size can be substantially reduced. Thus, a multiband radioelectric behaviour is achieved, that is, a similar behavior for different frequency bands.

Title: Document encryption permitting indexing by a search engine
Inventor: BANKS DAVID MURRAY
IPC: G06F21/62
Filed: 2001-07-05
Abstract: Documents are encrypted to allow access only to those users who have the appropriate decryption keys. Hitherto, the encryption of documents on public web servers has prevented indexing by search engines. The invention discloses a method of encryption in which elements, such as sentences, are tagged 6 and then re-ordered 12 within the document. The readability of the document is reduced to the point where a human reader can make no sense of the document, but, by keeping words or sentences intact, indexing of the encrypted document by a search engine is made possible. Preferably, a larger 'granularity' is used, for example sentences, paragraphs or chapters. The swapping or reordering of the elements within the document is controlled by a pseudo-random number generator 10. The pseudo-random sequence may be seeded with a number based on the original document, for example a hash value. The final state of the pseudo-random number generator and the number of iterations are used as a decryption key, seeding the same pseudo-random sequence 10-1 in the decryption process.

Title: Optical Vestigial Sideband (VSB) transmission
Inventor: WEBB STEVE
IPC: H04B10/155
Filed: 2002-09-18
Abstract: An optical vestigial sideband (VSB) generation control system 10 uses received signal quality as a measure for adjusting a VSB filter 15 or a signal wavelength to ensure optimum VSB signal transmission. The VSB filter which may be a Bragg grating acts to reject one of the sidebands generated by a laser source 14 (see figure 1). Preferably the bit error rate (BER) is measured at a remote receiver 13 which provides feedback control data to the transmitter 11. The control data is used to control either the wavelength of the laser source 14 (e.g. by controlling the temperature), or the cut-off edge of the VSB filter. The control loops proposed offer minimal complexity and implementation whilst providing reliable and understandable performance improvement. Application is to dense wavelength division multiplexed (DWDM) systems.

IPC: G01R11/00
Filed: 2000-05-05
Abstract: A digital meter (10) is designed for measuring alternating current and is formed of a metal rotary disk (20), a light-emitting element (30), a light-sensing element (40), a signal wire (50), and a signal conversion display (60). The metal rotary disk (20) is provided with a through hole (21) located at an appropriate position thereof. The light-emitting element (30) and the light-sensing element (40) are corresponding in location to each other such that they are located on a rotational path of the through hole (21). As the metal rotary disk (20) completes one revolution, the light-sensing element (40) receives a light signal which is transmitted via the signal wire (50) into the signal conversion display (60) by which the signal is converted (62) into a numerical value of power consumption. The numerical value of power consumption by a power user is thus attained by a terminal located in the power company without the use of a meter-person.
