Abstract: Cette invention concerne un procédé et un appareil permettant d'intégrer un système de communications personnel à une installation de télévision par câble. Un ensemble de dispositifs d'antennes radio (RAD)(50A-50I) sont connectés à l'installation de télédistribution (4). Les RAD (50A-50I) permettent de convertir les fréquences et de réguler la puissance du signal reçu de l'installation de télédistribution en vue d'une transmission sans fil vers des unités situées à distance (24A-24C). Les RAD (50A-50I) permettent également de réguler la puissance et de convertir le fréquences de signaux de communication sans fil reçus des unités à distance, en vue d'une transmission par lesdits RAD (50A-50I) vers l'installation de télédistribution (4). Outre le fait qu'elle remplit les fonctions de stations de base classiques et d'unité de commande centralisée, la station de base de télévision par câble va également compenser les variations de gain dans l'installation de télédistribution (4). Le réglage de la puissance vers l'aval se fait à l'aide d'un signal de référence des RAD (50A-50I) qui peut être caché à l'intérieur d'un signal AMRC en vue d'une efficacité maximale.

Abstract: A method and apparatus for forming a tensioned garter and bondingit to a substrate while holding the garter in a predetermined shape. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively wrapped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. In another embodiment each mandrel has a top surface. The upper portion of a garter has sufficient elastic tension to cause it to fold over the mandrel top surface to form a garter flange thereon. A substrate is then engaged with the garter flange and an external sealing means seals the flange to the substrate, using the mandrel top surface as an anvil. In still another embodiment the mandrel top surface has a raised outer rim. An ultrasonic horn seals a garter flange to a substrate where they are supported by the mandrel rim. The mandrel rim is shaped to provide a continuous seal which is weakened at its inner edge. When the weakened edge is broken, substrate and garter materials inside the seal edge are removed, thereby forming a hole around which the remaining portion of the garter may contract. Vacuum is applied from the mandrel top surface to the substrate inside the garter in this embodiment in order to break the seal edge and remove this material as the substrate and garter are stripped off the mandrel.

Title: System and method for sound synthesis using a length-modulated digital delay line
Inventor: STILSON TIMOTHY S
IPC: G10H7/08
Filed: 1997-05-06
Granted: 2004-10-19
Abstract: A sound synthesis system employs a variable-length delay line (154) whose length is modulated at a frequency that is close to the fundamental frequency of the delay line. By modulating the length of the delay line at a frequency close to the fundamental frequency of the delay line, a new class of sounds is generated. A delay line length modulator (156) produces a periodic modulation signal whose frequency is close to the fundamental frequency of the delay line. The length of the delay line is modulated in accordance with the modulation signal, thereby causing a variable pitch shifting effect in the waveform produced by the delay line structure. Since the length of the delay line (154) is modulated at a frequency close to the average loop frequency, part of the waveform stored by the delay line is time-compressed and the other part is expanded. The waveform's shape changes smoothly so that the compressed part of the waveform is pitch-shifted upwards, and the expanded part is pitch-lowered. A simultaneous upward and downward shift in the spectrum of the waveform stored by the delay line results, generating musically intriguing sounds. In one embodiment, a regeneration filter (252) introduces an instability into the delay line's feedback loop at a frequency of half the sampling rate. This introduces additional energy into the system which causes the waveform in the delay line (154) to regenerate, thereby increasing the length of time that sound effects are generated after the introduction of an excitatio n pulse.

Title: Braking system for an automotive vehicle including diagnosing device
Inventor: ISONO HIROSHI
IPC: B60T7/04
Filed: 1999-02-09
Granted: 2003-12-16
Abstract: A braking system for an automotive vehicle is provided herein. The braking system includes a brake operating member, a booster including an input rod and operable to boost a brake operating force acting on the brake operating member. A master cylinder is provided for producing a hydraulic pressure on the basis of an input force received from the booster as a result of boosting of the brake operating force by the booster. A wheel brake cylinder is activated by the hydraulic pressure which is produced by the master cylinder, to brake a wheel of the automotive vehicle. The brake system includes a connecting member connecting the brake operating member and the input rod to each other. It is configured so as to permit a relative movement between the brake operating member and the input rod of the booster in an axial direction of the input rod by a predetermined maximum distance. A pivotal member is connected to the brake operating member such that the pivotal member is configured pivotal about an axis which is perpendicular to the axial direction of the input rod, on the basis of the relative movement between the brake operating member and the input rod. A booster-diagnosing device is provided for detecting an input and an output of the booster, and for determining that the booster is abnormal, if the detected input and output do not meet a predetermined nominal relationship therebetween. The booster diagnosing device includes a signal generating device fixed either to the brake operating member or the pivotal member. The signal generating device is configured to operate in response to a relative movement between the brake operating member and the pivotal member which is caused by the relative movement between the brake operating member and the input rod. The signal generating device generates an output signal relating to the brake operating force as the input of the booster, depending upon the distance of the relative movement between the brake operating member and the input rod.

Abstract: A variable rate communication incorporating coherent signal processing and combining is described. Within the receive system (100, 102 and 106), vectors of in-phase and quadrature-phase Walsh correlator output values (W(i)1 and W(i)Q) are generated for each Rake finger over each Walsh symbol period. In-phase and quadrature-phase reference values (R(i)1 and R(i)Q) are generated for each of the Rake fingers by combining the in-phase and quadrature-phase correlator outputs of the most likely Walsh symbols over a series of Walsh symbol periods. The most likely Walsh symbols are determined on a symbol-by-symbol basis by summing the Walsh correlator output energies from each finger and selecting the largest. The vectors of in-phase and quadrature-phase values are then projected (116) on the in-phase and quadrature-phase reference values and weighted by the reference amplitude.  The vectors of projected and weighted values are summed via coherently combining (118), and the corresponding values from the other Rake fingers used to obtain a resultant vector of coherently demodulated Walsh correlator outputs (120). The coherently demodulated Walsh correlator outputs are used to form soft decisions (134, 136) that are deinterleaved and soft-decision Viterbi decoded.
