Abstract: The invention relates to a light diffuser (1) comprised of a holding device and of an at least partially transparent inflatable bag (3), which can be detachably connected to said holding device. The holding device is equipped with an adapter ring (4) provided for attachment to a projector (2) and for holding the bag. In addition, the adapter ring is closed such that it is transparent and pressure sealed with regard to the attachment side, and means for supplying a gaseous filling medium are provided on the holding device.  According to the invention, a compressed gas connection and an electronically actuatable valve for supplying gas are provided on the adapter ring. A first pressure sensor (7) determines the increasing inner pressure when the sack is fixed to the ring and sends a switch-off signal to the valve once an adjustable maximum pressure value is reached in order to automatically stop the filling. A second sensor (11) is also provided for detecting the ambient pressure so that a switch-off signal can be derived based on a predeterminable differential pressure value.

Abstract: A network interface unit is provided for use intermediate a LAN and a public or private network, or a combination of both, for establishing secure links to a VPN gateway. Login by a LAN client with the network interface unit, addressing, authentication, and other configuration operations achieved using a web page-based GUI are applied in establishing tunnels from LAN clients to desired VPN destinations.  Illustrative network interface units include a DHCP server and provide encryption-decryption and encapsulation--decapsulation of data packets for communication with VPN  nodes. Configuration and connection of a client are further enhanced by a built-in DNS server and other functional servers to provide a high degree of autonomy in establishing connections to a desired VPN gateway via an ISP or other public and/or private network links to. The interface unit then performs required authentication exchanges, and required encryption key exchanges.

Abstract: A solid fuel burner using a low oxygen concentration gas as a transporting gas of a low grade solid fuel such as brown coal or the like and a combustion method using the solid fuel burner are provided. The solid fuel burner comprises a means for accelerating ignition of the fuel and a means for preventing slugging caused by combustion ash from occurring. Mixing of fuel and air inside a fuel nozzle 11 is accelerated by that an additional air nozzle 12 and a separator 35 for separating a flow passage are arranged in the fuel nozzle 11, and the exit of the additional air nozzle 12 is set at a position so as to overlap with the separator 35 when seeing from a direction perpendicular to a burner axis, and additional air is ejected in a direction nearly perpendicular to a flow direction of a fuel jet flowing through the fuel nozzle 11. An amount of air from the additional air nozzle 12 is varied corresponding to a combustion load. By increasing the amount of air from the additional air nozzle 12 at a low load operation, an oxygen concentration of a circulation flow 19 formed in a downstream portion outside the exit of the fuel nozzle 11 is increased to stably burn the fuel. By decreasing the amount of air from the additional air nozzle 12 at a high load operation, a flame is formed at a position distant from the fuel nozzle 11 to suppress radiant heat received by structures of the solid fuel burner and walls of the furnace.

Abstract: An in-band signaling method that enables secure updates of a care-of IP address for a mobile host that roams between access networks. In the illustrative embodiment described herein, a mobile host includes an intelligent interface that handles IP networking functions and tunnels IP packets between the mobile host and the mobile host's home agent/remote access server (HA/RAS) transparently, as if the mobile host established a connection to a communicating or destination host (DST) from the home network (where the HA/RAS resides). In accordance with an aspect of the invention, there is provided an in-band signaling method that employs encrypted three-way handshake signaling messages that are embedded in encapsulated IP packets to enable care-of IP address updates. This method can effectively protect mobile hosts from denial-of service attacks and is transparent to NAT/NAPT firewalls. The signaling messages are communicated between the home agent and the mobile host, in a manner transparent to any NAT/NAPT firewall in the network.

Abstract: A wood chip loading device loads wood chips into a container with a density greater than that achieved using conventional free-fall techniques by 20%-35%  or more. The wood chip loading device may include a drum rotating about a generally horizontal axis. The drum includes a plurality of outwardly extending blades that act to fling the wood chips out in a truncated sector pattern. The wood chips form a wide-based stack in the container such that the wood chips have a substantially uniform orientation, thereby allowing for greater packing densities. The device may also include a feed chute assembly that allows for adjustment of the ratio of the input stream that is delivered to the middle and side portions of the spinning drum. In some of these embodiments, this adjustment may be made while the device is operating, thereby allowing for on-the-fly adjustments by the operator.

Abstract: L'invention concerne la simulation d'effets dans un environnement de combat, où le personnel, les véhicules et les bâtiments sont exposés à un tir simulé sous forme d'armes militaires. Un tir direct et un tir indirect sont simulés par au moins des rayons lumineux (111) et des ondes radio (121). Les effets du feu d'attaque sont enregistrés à l'aide d'un dispositif objet cible (145) qui comporte des détecteurs conçus pour détecter les rayons lumineux (111) ou les ondes radio (121) et situés sur l'objet cible (140). Selon l'invention, l'objet cible (140) est associé à au moins un objet de protection (130a; 130a') situé entre le tir simulé (111; 121) et l'objet cible (140) si un tel objet existe dans la situation de combat courante. Cela permet de considérer l'effet de divers objets de protection (130a; 130a') sur le tir simulé et les effets sur le tir actuel correspondant. L'invention simule ainsi les effets de tir direct et de tir indirect de manière réaliste, ce qui à son tour donne des chances d'un comportement adéquat du personnel en formation dans une situation réelle correspondante.

Granted: 2007-10-02
Abstract: Système modulaire de transfert pneumatique pour convoyeur à bande équipé de blocs de transfert individuels en plastique sur lesquels la bande circule. Utilisé comme système de transfert à aspiration, chaque bloc de transfert fait partie d'un module d'aspiration autonome. Chaque module intègre un jet d'air à basse pression agissant comme moyen de détection d'une réaction pour déterminer la présence d'un article sur la bande. Un pavillon d'aspiration activé par l'air et comportant plusieurs phases, fonctionnant comme un éjecteur d'air, fournit une forte aspiration dans le bloc d'aspiration. Une commande pneumatique activée par les moyens de détection active le pavillon d'aspiration et applique une force d'aspiration sur le bloc visé. Cette succion au niveau du bloc est appliquée aux perforations de la bande, aspirant ainsi vers le bas l'objet détecté sur la bande, ce qui permet son transfert. Les blocs peuvent aussi servir de modules à coussins d'air, dans un mode de support. Le moteur synchrone de la bande est situé dans la section centrale du convoyeur, la position de la bande en fonction des postes de travail placés le long de la courroie étant déterminée par le contrôleur du moteur. Par exemple, un moteur électrique synchrone permettant l'arrêt et le démarrage précis du convoyeur (y compris la marche arrière) relativement aux postes de travail adjacents. L'entraînement direct de la bande de transfert peut se faire au moyen d'une bande de transfert crantée. Bon nombre de convoyeurs du genre peuvent fonctionner côte à côte, actionnés par un arbre d'entraînement cannelé partagé. Les rouleaux guides du système peuvent être faits de plastique, des paliers d'appui étant placés dans une ou deux extrémités du rouleau, ce qui permet de remplacer le rouleau à peu de frais. La poutre extrudée sur laquelle les blocs de transfert circulent contient quatre galeries techniques depuis lesquelles de l'air haute pression et de l'air basse pression sont approvisionnés dans le système
