Filed: 1997-09-26
Abstract: Pour l'affichage de certaines scènes vidéo, dans le cas où les premières données de restriction sont à un niveau plus contraignant que les secondes données de restriction, un circuit d''écran (5) fonctionnant en accord avec la sortie d'un comparateur (3) altère l'affichage de l'écran du téléviseur (6) avec une seule couleur pré-déterminée, qui masque la scène. En revanche, dans le cas où les premières données de restriction sont à un niveau moins contraignant que les secondes données de restrictions, le circuit d'écran (5) fonctionnant en accord avec la sortie d'un comparateur (3) affiche la scène vidéo non censurée.  En outre, l'étendue de l'écart entre les niveaux de restriction des premières et secondes données de restriction peut être contrôlée à l'écran du téléviseur (6) au moyen d'un ensemble de données dans le registre des attributs (9), afin de prévenir le réglage d'un niveau de restriction trop permissif.

Inventor: DANCS IMRE J
IPC: A61L9/12
Filed: 1996-05-08
Abstract: A dispensing device for dispensing a volatile active ingredient from an air-transmitting substrate that forms a part of a refill assembly. The dispensing device includes a housing with an intake vent and an exit vent and an air flow path extending between them. Refill assembly support means are provided for removably supporting the refill assembly with its substrate located in the air flow path. Battery-powered fan means are provided for propelling air from the intake vent through the substrate and out the exit vent. A battery holder holds a fan battery in such a manner that a refill assembly not fully inserted within the refill assembly support means blocks the placement of a battery in the battery holder, while a battery correctly held in the battery holder blocks the removal from the air flow path of a refill assembly supported by the refill assembly support means. Thus, successful placement of a battery in the battery hold serves to both verify and maintain the correct placement of the refill assembly in the air flow path. An air-transmitting refill assembly for use with the dispensing device includes an air-transmitting substrate and a tab attached to the margin of the substrate. The tab has a brace surface facing generally away from the substrate and shaped to engage the surface of a battery being held within the battery holder of the dispensing device.

Title: Quality calculator for viterbi-decoded data using zero-state metrics
Inventor: CHOI SUNG-HAN
IPC: H04L69/40
Filed: 1998-01-07
Abstract: A quality calculator for Viterbi-decoded data, using zero-state metrics, is provided.  The quality calculator for the Viterbi-decoded data includes: a Viterbi decoder which outputs zero-state metrics of input demodulated data, according to four possible transmission rates of FULL, HALF, QUARTER and 1/8; a register which stores respective zero-state metrics output from the Viterbi decoder; and a quality evaluation unit which reads the zero-state metrics stored in the register, to evaluate the Viterbi-decoded data based on the zero-state metrics, and which determines the actual transmission rate to be the one among the possible transmission rates which has the least zero-state metrics.   Therefore, the zero-state metrics of the demodulated data input to the Viterbi decoder are used as a quality evaluation parameter, so that the quality evaluation can be correctly achieved to avoid errors in the determination of the transmission rate, compared to a quality calculator using a bit error ratio as the quality evaluation parameter.

IPC: A61M36/04
Filed: 1996-07-11
Abstract: An irradiation apparatus has at least one exchangeable radiation source that may be moved by means of a transport cable between at least one rest position and at least one irradiation position and a long-distance transport container for radiation sources to be exchanged. In order to reduce the danger of control errors, the rest position is located inside the long-distance transport container (20) and the transport container forms or may form an integral part of the irradiation apparatus. For that purpose, interface elements are provided on the transport container and other parts of the irradiation apparatus. By winding and unwinding the transport cable on and from a feeding drum (40) with a cable-receiving groove (41') at least partially covered by a pressing strip (41), particularly thin transport cables may be used, so that the width of the pressing strip (41) substantially corresponds to the width of the cable-receiving groove (41'). The pressing strip (41) is helically wound in the cable-receiving groove (41') around the feeding drum (40), in the axial or radial direction with respect to the feeding drum (40), and the cable-receiving groove (41') is thus covered in a substantially uninterrupted manner. Means for lifting, preferably also for deflecting and lowering again the pressing strip, may be moved along the transport cable (4) in relation to the feeding drum (40) in order to let free an output point (42) for the transport cable (4) from the feeding drum (40).

Patent CA-2232981-A1 (CA)
Inventor: GREEN ANDREW WILLIAM
IPC: H05B41/282
Filed: 1996-10-04
Abstract: Disclosed is inductive coupling of power to devices having negative resistances, such as gas-filled discharge lamps (fluorescent tubes, neon signs, and the like) from a primary inductive loop, using resonant conditioning of the power provided to the device. A "C" shaped inductor (202) around the loop and a resonating capacitor (406) in parallel with the inductor provide a current source to the lamp (403) from across the capacitor. The circuit is capable of first igniting a lamp using a higher voltage available when the Q of the unloaded circuit is high, then running the lamp or other device at a controlled current. The lamp current is substantially proportional to the primary inductive loop flux, and substantially independent of the lamp resistance. A second inductor (404) in series with the first though not itself a collector of flux acts as a current limit. Applications include lighting, displays (optionally isolated and dimmable), and production of ultraviolet radiation.
