Title: Chroma keying studio system
Inventor: TZIDON AVIV
IPC: H04N5/272
Filed: 1997-01-29
Granted: 2003-09-23
Abstract: A video system is described which creates a virtual shadow of a foreground object filmed in front of a blue screen with a main video camera. The virtual shadow is created using a second video camera located as a virtual light source. Images from both cameras are processed by a chroma keyer to separate the foreground object. The video ima ge from the second camera is processed to create the virtual shadow and both video images are combined with background image. Object location and actor prompting systems are described to enable an actor to easily find his way around the set, and to focus his gaze on the virtual objects appearing in or disappearing from the studio. The prompting system gives the actor the timings for various events taking place in the studio. The special markings are completely invisible to the camera and to the home viewers because they are either projected in a chroma-key color, or are only active during virtual blanks of the camera such as the vertical blanking interval or the horizontal blanking interval in an NTSC, PAL, SECAM or other video signal format.

Abstract: A releasable retention assembly includes an elongated flexible member, a retention member and a lock mechanism. The flexible member has opposite end portions and a length sufficient for wrapping at least once about an utility pole to retain a cover in place on the utility pole. The retention member is secured to one opposite end portion of the flexible member and defines a slot through which the other opposite end portion of the flexible member can extend. The lock mechanism includes a latch element mounted to the retention member for undergoing pivotal movement between angularly displaced latched and unlatched positions relative to the other opposite end portion of the flexible member extending through the slot of the retention member. In the latched position the latch element is engaged with and wedges the flexible member within the slot against the retention member to thereby hold the other opposite end portion of the flexible member stationary in relation to the retention member and maintain the flexible member tightened about the utility pole. In the unlatched position the latch element is disengaged from and unwedges the flexible member within the slot to thereby allow the flexible member to loosen about the utility pole. The lock mechanism also includes a spring element biasing the latch element to the latched position and a release lanyard that may be actuated to move the latch element from the latched position to the unlatched position.

Granted: 2004-07-20
Abstract: La présente invention concerne un procédé consistant à conduire une dispersion provenant de la zone de mélange et à la faire passer du bas vers la zone liquide du décanteur dans la zone médiane d'extrémité libre. A partir de ce point, la dispersion est mise à reposer de façon à être répartie à l'intérieur de la zone de décantation. La circulation se fait en utilisant un espace canal fermé situé au voisinage immédiat du décanteur, et aboutissant en pleine largeur du décanteur. A partir de ce point, la circulation se fait principalement au-dessus de l'espace canal en direction de l'extrémité postérieure du décanteur. Ce procédé utilise un appareil dans lequel un arbre de conduction, qui s'étend du réservoir de mélange de dispersion au décanteur, débouche dans l'extrémité d'alimentation du décanteur. A partir de ce point, les canaux de distribution partent ensuite vers les bords latéraux du décanteur. Ces canaux de distribution sont situés dans le fond du décanteur.

Abstract: L'invention concerne des récepteurs DS-CDMA, et plus particulièrement le besoin de fournir un filtre accordé sur l'impulsion permettant d'éliminer les interférences entre puces. On utilise un récepteur RAKE CDMA. Au lieu d'appliquer un filtre accordé sur l'impulsion au signal d'entrée comme c'est le cas dans les systèmes selon l'état de la technique, on applique un filtre accordé sur l'impulsion à un bit à la séquence de dispersion, de préférence, à une séquence de bruit pseudoalétoire (PN) interpolée jusqu'à la fréquence de suréchantillonnage requise. Le filtre ayant une entrée à un bit, on peut remplacer les multiplicateurs par des sommateurs qui consomment moins de courant. Contrairement au nombre de multiplicateurs selon l'état de la technique, le nombre de sommateurs n'augmente pas avec la fréquence de suréchantillonnage.

Abstract: The present invention utilizes dielectric slabs to provide a relatively uniform electromagnetic field to a cavity between two or more dielectric slabs. Each dielectric slab is a thickness equal to or nearly equal to a quarter of a wavelength of the electromagnetic field in the dielectric slab. In a particular embodiment, sample material is introduced into the cavity between the two dielectric slabs. This sample material may be introduced through one or more openings in the dielectric slabs. In further embodiments , specialized choke flanges prevent the leakage of energy from this cavity. In a preferred embodiment, an elliptical conducting surface directs the electromagnetic field to a focal region between the two dielectric slabs. Openings to this focal region allow sample material to be passed through thi s region of focused heating.
