Abstract: A steam iron with a valve between the water reservoir and the soleplate. The valve has a valve stem that is connected to the temperature control. The valve stem is axially rotated when the temperature control is moved without longitudinally moving the valve stem. The valve stem has a groove of varying depth located between an inlet and an outlet of the valve member to vary the flow of water through the valve based upon the rotational position of the valve stem relative to the valve member.      A user actuated mechanism is also provided to longitudinally move the valve stem among closed, variable, and non-variable open flow positions.

Abstract: A tracked vehicle includes an engine driven variable displacement steering pump which drives a hydraulic steering motor. The steering motor drives a differential drive mechanism which drives left and right track drive wheels. A steering control system senses the position of a non-spring centered steering wheel, vehicle speed, engine speed, steering motor speed, whether or not the transmission is in gear or in neutral, and whether the clutch is engaged or disengaged. In order to prevent a self-perpetuating turn situation, the control system gradually decreases the steering motor speed if the transmission is in neutral or the clutch is not engaged, and the steering motor speed divided by the vehicle speed is greater than a threshold, and the vehicle speed is less than a reference level.

Title: Aremac--based means and apparatus for interaction with computer, or one or more other people, through a camera
Inventor: MANN STEVE
IPC: G02B27/18
Filed: 1998-12-24
Granted: 2001-10-16
Abstract: A new kind of display means and apparatus called an aremac is provided.  The aremac may either be worn upon the body, such as in a pair of eyeglasses, where it can direct light into an eye of the wearer of the apparatus, or it may be located together with a fixed camera to direct light onto a three dimensional scene or objects. The typical application of the aremac is that of collaborative photography, in which a remote director assists a photographer in composing a picture, or arranging lighting in a photographic studio while the remote director remotely views the scene through the photographer's camera.  In a wearable embodiment, the camera is effectively imaged inside an eye of the wearer so that the remote director can view the light rays passing through an eye of the wearer of the apparatus and the director can write on the retina of the wearer of the apparatus by pointing a laser beam at the screen in the director's office, which teleoperates a miniature laser beam directed through the wearer's eye lens onto the retina of an eye of the wearer in such a manner that when the director points at an object in the scene, the wearer of the apparatus sees a red dot at the corresponding location on that same object.  In another embodiment, the remote director can point to objects in the photographer's studio by pointing a laser beam at a projection screen which displays images of these objects in the photographer's studio, where the director's laser pointer remotely controls a teleoperated laser pointer in the photographer's studio.

Abstract: A method for use in a packet switching network for selecting a route between a source node and a destination node. The route satisfies a Quality of Service (QoS) profile and the source node stores in a route cache a plurality of pre-computed routes originating at the source node, and the source node is connected to a route server. The method includes the actions of searching the route cache for a route satisfying the QoS profile; if no satisfying route is found in the route cache, then a route from the server satisfying the QoS  profile is obtained; and updating the contents of the route cache based on network usage.

Abstract: Uniform Resource Locators (URLs) or other network information identifiers embedded in television signals are processed in order to permit viewers to customize the display of a corresponding program. In an illustrative embodiment, at a time prior to the scheduled display of a program or portion thereof, a given viewer makes a selection of one of a number of available alternate characteristics for the program, such as one of a number of available alternate endings. At a later time, a base URL embedded in the television signal is extracted and processed using the viewer selection in order to generate a combined URL. The combined URL is then used to establish a connection over a network with a corresponding web site or other information source, and information is retrieved from the web site and stored in a memory. The retrieved information is subsequently taken from the memory and used to modify the manner in which the program is displayed to the viewer. For example, the retrieved information may include video which is displayed to the viewer in place of a portion of the program.

Abstract: La présente invention concerne des compositions polymères époxy-polysiloxane préparées par l'association d'un constituant résinique avec un constituant durcisseur. Le constituant résinique comprend un ingrédient résinique époxy non aromatique et un ingrédient polysiloxane. Le constituant durcisseur renferme une amine et éventuellement un catalyseur organostannique. La composition peut également contenir des agrégats, des pigments et d'autres additifs selon l'usage final spécifique. La composition se prépare à l'aide d'une quantité suffisante d'eau pour faciliter l'hydrolyse du polysiloxane et la polycondensation des silanols produits par cette hydrolyse. Sous sa forme polymérisée, la composition époxy-polysiloxane se présente sous la forme d'un arrangement uniformément dispersé de fragments de chaîne époxy linéaires qui sont réticulés avec une chaîne polymère polysiloxane continue, formant ainsi une structure chimique à réseaux polymères non enchevêtrés, laquelle offre des avantages notables par rapport aux systèmes époxy classiques. Des revêtements protecteurs formés à partir de ces compositions présentent une excellente stabilité aux agents atmosphériques tels que la lumière solaire, et une résistance supérieure aux produits chimiques et à la corrosion après polymérisation.

Abstract: L'invention concerne un appareil (100) de communication qui se commute automatiquement et en continu à un système de secours disponible lorsqu'il est incapable d'établir une tentative d'émission d'appel sans demander à l'utilisateur de prendre des actions positives en vue de sélectionner le système de secours ou de recommencer une émission d'appel. L'appareil (100) de communication sans fil comporte un poste émetteur-récepteur (104) et un processeur (104). Le poste émetteur-récepteur (107) émet et reçoit des messages et des signaux. Le processeur (107) génère un premier message de signalisation, destiné à être transmis à un premier système de communication, et génère un second message de signalisation destiné à être transmis à un second système de communication au cas où le poste émetteur-récepteur ne reçoit pas de message d'accusé de réception du premier système de communication. Ce procédé fait diminuer le pourcentage d'appels infructueux en assurant un retardement des tentatives d'émissions d'appels en attente jusqu'à ce que le service soit finalement obtenu. En cas, soit de dépassement du nombre maximum de séquences d'accès (liaison de retour limitée), soit de la non obtention de la liaison aval du système de communication préféré (liaison aval limitée), on ne demande pas à l'utilisateur de recommencer l'émission d'appel, ce qui transforme ainsi un appel infructueux potentiel en un succès.
