Abstract: An impression tray for a dentate human jaw having a mobile mucosa and a stationary mucosa with a linear action boundary between the mucosae, the tray having an envelope which in plan follows the U-shape of the dental arch of the jaw and which has a U-shaped trough cross-section near the dental arch, the envelope having a buccal edge and a lingual edge or a palatal edge, the buccal edge and the lingual or palatal edge terminating substantially in the region of the mobile mucosa, the envelope being fillable with an impression material and being pressable onto the jaw. The U-shaped trough cross-section of the envelope extends around the associated dental arch and the stationary mucosa at a distance from them of less than 5 mm, preferably approximately 1 mm. The buccal edge and the lingual edge or palatal edge are pressable onto the mobile mucosa as a sealing strip beyond the action boundary near the mobile mucosa at least with the mobile mucosa mobilized. A narrow gap of, for example, at most 1 mm width can be left in places.

IPC: H04N5/12
Filed: 1991-03-25
Abstract: A circuit for receiving a video signal with a horizontal synchronizing component at a horizontal scanning frequency generates an intermediate synchronizing signal synchronized with the horizontal synchronizing component. A horizontal deflection circuit generates horizontal deflection current synchronized with the intermediate synchronizing signal. An oscillator generates a display locked clock signal synchronously with a clock synchronizing signal derived from the horizontal deflection current. A counter divides the clock signal, producing decodable outputs. A decoding circuit generates display locked timing signals, at the frequency of the horizontal synchronizing component and at the frequency of the intermediate signal, from the outputs of the counter. Where the frequency of the intermediate signal is a multiple of the frequency of the horizontal synchronizing component, for example by a factor of two, a circuit coupled to the counter and the decoding circuit associates certain pulses of the display locked clock signal with commencement of video line intervals in the video signal.

Abstract: "SISTEMA DE RECONHECIMENTO BIOMéTRICO E PROCESSOS PARA GERAR UM CONJUNTO DE PADRõES MESTRES DE UMA INDICAçãO BIOMéTRICA DE UM USUáRIO E PARA AUTENTICAR UM PADRãO BIOMéTRICO DE UM USUáRIO". Um sistema de reconhecimento biométrico envolve duas fases: criação de um conjunto de padrões mestres de uma indicação biométrica de usuário autorizado, e autenticação, usando uma rede neural de classificação. Para criar o conjunto de padrões mestres, uma imagem de uma indicação de usuário biométrico autorizado é dividida numa pluralidade de regiões de interesse ou "traços" e ou "feições". O sistema determina quais os trações que são mais úteis para fins de indentificação. São então criados padrões mestres a partir destes traços mestre, criando assim um conjunto mestre. Durante a autenticação, um conjunto de padrões de amostra de um usuário a ser autenticado é similarmente criado. Uma rede neural é usada para comparar o conjunto de padrões de amostra com o conjunto de padrões mestres para determinar se o usuário deve ser autenticado.

Abstract: The invention pertains to a method for crediting or recrediting a SIM card (subscriber identity module) for a mobile radio telephone (6) with a given amount (28). The SIM card comprises a chip provided with a memory element (11). The amount is stored in said memory element (11) and decreases as the mobile radio telephone is used. In order to credit or recredit a SIM card, the user must possess a memory board (13) payable in advance. The memory board (12) has a code area (14) covered with a nontransparent detachable film (22). A code (15) appears upon detaching the film (22). The SIM card (7) and memory board (13) holder dials a service number from a telephone (6, 8), the calling party thereby being connected to a data bank (17) where all codes allocated to memory boards (15) and the corresponding amounts (12) are recorded. The calling party is requested to input his code number into the telephone (6, 8) with which he is calling. Once entered, the code is compared with the code recorded at the data bank. As soon as the code (15) has been retrieved, a short message with the amount to be credited or recredited is temporarily recorded at the short message service center (18, 19). The amount (28) and the code (15) registered at the data bank (17) are then marked as depleted or erased. Next time the holder inserts his SIM card (7) into any mobile radio telephone and sets up a connection with the telecommunication network (9), said card will be credited or recredited with the amount (28) temporarily recorded on the basis of the prepared short message (20).
