Abstract: A sash balance brake and pivot pin assembly for a sash window that maintains the window substantially square prior to installation is disclosed. The pivot pin extends outwardly from the window sash. The sash balance brake is disposed within a track in the window frame and includes a rotor rotatably disposed within an expandable housing. The pivot pin has a collar for lateral en-gagement with the rotor to prevent the window frame from bowing away from the window sash, thereby maintaining the window frame substantially square. The rotor has a first slot and a transversely disposed second slot defining an inner surface. The inner surface includes an angled surface to resist breakage of the rotor when the window sash in installed into the window frame. The rotor also has a pair of flats at a first end to further resist breakage of the rotor when the pivot pin is positioned at an angle with respect to the rotor.

Abstract: Dans un spectromètre de masse, généralement de type quadripolaire, un des ensembles à tiges est conçu de manière à pouvoir générer un champ axial, par exemple, un champ axial à courant continu, sur l'appareil. On crée un champ axial en taillant les tiges en cône, ou en disposant les tiges en angle les unes par rapport aux autres, ou en segmentant les tiges, ou en plaçant un boîtier segmenté autour des tiges, ou en utilisant des tiges à revêtement résistif ou des tiges auxiliaires segmentées, ou en utilisant un jeu de bandes métalliques conductrices en les espaçant le long de chaque tige avec un revêtement résistif entre les bandes, ou en transformant chaque tige en un tube doté d'une couche externe résistive et d'une couche interne conductrice, ou en utilisant d'autres procédés appropriés. Lorsqu'on applique le champ axial à la tige Q0 dans un ensemble quadripolaire en tandem, le champ accélère le passage des ions à travers la tige Q0 et réduit la temporisation causée par la nécessité de remplir la tige Q0 de ions en passant d'une masse inférieure à une masse élevée dans la tige Q1. Lorsqu'il est utilisé comme cellule de collision Q2, le champ axial diminue la temporisation nécessaire au drainage des ions filles hors de la tige Q2. On peut également employer le champ axial pour favoriser la séparation des ions dans la tige Q2, soit en forçant les ions à se déplacer vers l'avant contre le gaz de collision, soit en faisant osciller les ions axialement à l'intérieur de la cellule de collision.

Abstract: A compact movable ramp assembly is provided that can be securely stored beneath a vehicle floor and safely and reliably operated. The ramp assembly comprises a mounting structure having a series of top panels that form the vehicle floor. The ramp assembly also includes a moveable platform that deploys outward from the mounting structure forming an extended ramp from the ground level to the vehicle to allow the passage of passengers across the platform into and out of the vehicle.       The compact design of the ramp assembly is achieved by enclosing the motor unit within the ramp assembly and positioning the drive mechanism above the moveable platform but below the top panels of the mounting structure. The platform is formed of two portions pivotally connected by a hinge which enables the platform to pivot downward and allows the ramp assembly to be used in partial stages of deployment.

Abstract: A low complexity, high performance trellis decoder adapts the complexity of the trellis decoding process based on a current condition of the communications system.      A trellis structure of nodes and branches is developed to decode the sequence of symbols received over a communications channel. Each set of nodes in the trellis represents the possible values of a received symbol at one time instant. Each branch defines a specific transition between nodes at different time instants, and each branch has an associated branch metric or weight.      A linkage of branches between the nodes and the trellis defines a path through the trellis that represents one possible symbol sequence, and an accumulated metric/weight is generated for each possible path through the trellis. A variable number M survivor paths through is determined based on their accumulated path metric/weights. The value of the variable M depends on the current condition of the communications system. Once the value of M is adapted to the current condition, the sequence of received symbols is decoded using M survivor paths through the trellis.

Abstract: A method, system, and computer program by which a logical network connection can be maintained in the presence of disruption or failure of the underlying physical network connection. The technique defines a virtual connection between the client and gateway, which is not dependent upon continuous connectivity in the underlying physical connection, and can resume operation transparently even though the physical connection may be established on a different media type. Additionallv, the technique of the present invention enables the physical medium to be changed even though the physical connection was not disrupted. This change in medium may be based on a number of factors, such as quality of service or transmission speed, which can be monitored. A graphical user interface ("GUI") is defined whereby the human user may observe a depiction of the available physical connections and their status, information regarding the physical connection currently in use, etc. The user may initiate changes to the current physical connection from this GUI, without disrupting the logical connection.
