Abstract: L'invention concerne un générateur d'énergie à statoréacteurs. Des statoréacteurs supersoniques sont prévus le long d'une partie du pourtour d'un rotor à faible frottement aérodynamique. Le rotor est fixé par un moyeu central à un arbre rotatif. Le rotor sert d'élément de structure transmettant à l'arbre la poussée produite par les statoréacteurs. Dans le mode de réalisation préféré, un orifice d'entrée de statoréacteur capte et comprime un écoulement d'air entrant au moyen du profil d'arête du rotor, des onglets de confinement qui sont fixés sur le rotor de façon adjacente au module de poussée, et d'une paroi latérale de logement périphérique adjacent et de préférence fixe. L'écoulement entrant d'air comprimé fournit de l'oxygène qui se mélange avec un carburant tel que du gaz naturel, d'autres hydrocarbures appropriés, ou de l'hydrogène. Le carburant est oxydé dans la/les chambre(s) de combustion de statoréacteur pour produire des gaz de combustion dilatés. Ces gaz de combustion s'échappent en exerçant une poussée contre l'étranglement de l'orifice de sortie de statoréacteur, les structures d'onglet adjacentes et la paroi de logement périphérique adjacent, en faisant tourner le statoréacteur à des vitesses supersoniques et en produisant de l'énergie d'arbre. Une onglet hélicoïdal sépare efficacement le mélange entrant carburant-air des gaz de combustion sortants. Dans un mode de réalisation, l'onglet comporte en outre plusieurs orifices de refroidissement qui permettent aux gaz de refroidissement de passer à travers l'onglet, et aussi de réduire l'épaisseur de couche limite, ce qui permet de réduire les frottements.

Abstract: A keyboard matrix circuit includes means defining a first junction location and a second junction location. Two switches are wired in parallel between the junction locations, each switch being in series with a diode, and the two diodes being oppositely directed. Each junction location connects to line voltage along a current path which includes a resistance, so that current flow from line voltage to the respective junction location will cause that junction location to have a voltage lower than line voltage. For each junction location there is defined a current path permitting current to flow away from the respective junction location. Also, for each junction location current path there is provided a control means which either allows or disallows current flow along the respective location current path. Monitoring means, preferably in the form of gates, are.provided for detecting the voltage level at the respective junction location, thus providing a reading from which can be determined the open/closed status of the respective switch.

IPC: B65C9/18
Filed: 1999-06-24
Abstract: The invention relates to a device for applying a decoration to containers such as, for example, crates, bottles or cans. The decoration comprises an image transfer label supplied to the containers on a carrier strip. The carrier strip is pressed laterally, by means of a pressure roller, against the containers, which are fed past the pressure roller. A  heating device, such as, preferably, a hot air blower, heats the image transfer label on the application side of the carrier strip. Preferably, a flat stream of air is blown, by the hot air blower, against the line of contact between the image transfer label and the container. As a result of the use of highly local heating of the application side of the carrier strip according to the present invention, activation of the image transfer label is obtained without the carrier strip or the surface of the container being heated to a substantial extent. As a result, undesired stretch in the carrier strip is prevented and the temperature of the image transfer label can remain relatively low, so that the quality of the inks is retained and complete transfer to the containers is possible. The pressure roller is also able to operate at relatively low temperatures, so that a long life thereof is obtained. As a result of the highly local heating on the application side, the contact time required for transfer of the image transfer label is reduced substantially, so that a high throughput is possible.

Title: Modified chroma keyed technique for simple shape coding for digital video
Inventor: CHEN XUEMIN
IPC: H04N7/26
Filed: 1999-08-23
Abstract: An efficient chroma key-based coding technique for digital video with an optimized switching threshold. An optimized binary keying threshold (T) is provided for switching between a first image region (such as a background region) (B) and second image region (such as a foreground object) (A) video picture. The threshold optimizes a PSNR of a quantization error Q of a key color K. A chroma key technique is also provided for representing the shape of a video object, where the shape information (alpha plane) of a foreground object is embedded in the keyed output, so there is no need to carry an explicit alpha plane, or use alpha plane coding. The chroma key shape representation technique provides a smooth transition at the boundary (500, 505) between objects without the need for special switching patterns, such as a general gray scale shape coding tool, or post-processing, e.g., using feathering filters.

Title: Method and apparatus for controlling equalizer using sync signal in digital vestigial sideband system
Inventor: KIM KI-BUM
IPC: H04N5/21
Filed: 2001-08-28
Abstract: A method and apparatus for controlling an equalizer using a sync signal in a digital VSB system is provided, in which the sync signal is accurately separated even though a ghost having a short delay time and a large size is generated, and thus the equalizer is controlled with the separated sync signal. For this purpose, a switching unit is provided between a matched filter and an equalizer, which selects one of two input signals according to a NTSC rejection filter (NRF) on/off control signals and separates a data segment sync signal and a data field sync signal from the selected signal. A  control signal is produced via the separated sync signal to control the equalizer to operate at one mode of a blind mode and a training sequence mode. Since the equalizer performs sync signal separation by using the ghost removed signal, a system initial operational time becomes shorter, and accurate sync signal separation is possible even if severe ghosts occur, to thereby improve degeneration of system performance greatly.
