  • Publication number: 20180062323
    Abstract: An electrical connector for high speed signals. The connector has multiple conductive elements that may serve as signal or ground conductors. A member formed with lossy material and conductive compliant members may be inserted in the connector. The conductive compliant members may be aligned with conductive elements of the connector configured as ground conductors. For a connector configured to carry differential signals, the ground conductors may separate pairs of signal conductors. The member may further include a conductive web, embedded within the lossy material, that interconnects the conductive compliant members. For a receptacle connector, the conductive elements may have mating contact portions aligned along opposing surfaces of a cavity. The conductive elements may have contact tails for attachment to a printed circuit board and intermediate portions connecting the mating contact portions and the contact tails. The conductive compliant members may press against the intermediate portions.

  • Publication number: 20180033302
    Abstract: A method of guiding a user to a suitable parking spot is a method used to aid a user in finding a suitable parking spot near a desired location. The method uses at least one remote server and a mobile computing device. The remote server manages information related to potential parking spots, and performs calculations to determine if a potential parking spot is a suitable parking spot. The mobile computing device monitors the location of the user and allows the user to interact with the method. A parking search request is sent from the mobile computing device to the remote server. Upon receiving the parking search request, the geospatial vehicle detection system is used to locate potential parking spots. At least one filtering process is used to identify suitable parking spots from the potential parking spots, before the suitable parking spots are displayed to the user.

  • Publication number: 20180025066
    Abstract: Technologies are described for performing database updates in a database environment where the database remains accessible during the updates. For example, a number of database clients may utilize a database environment for running queries or performing transactions. When an update to the database environment needs to be performed (e.g., a change to the database schema), instead of taking the database offline or queueing requests, the database can remain accessible to the database clients throughout the update process. The update process can include switching database connections between a first copy of the database and a second copy of the database that are being replicated. Technologies are also described for performing updates to application code used to interact with the database environment (e.g., alone or in combination with database system updates).

  • Publication number: 20170348934
    Abstract: Exemplary embodiments of the subject invention comprise methods and apparatus for mounting a tread ring onto a tire carcass. Such methods include providing a tire tread ring having opposing side edges, arranging the tread ring in an initial ring arrangement in communication with a pressure source, and expanding the tread ring radially outward from the initial ring arrangement to an expanded arrangement. The pressure source is in communication with an outer side of the tread ring, the tread ring being expanded by applying vacuum pressure along the outer side of the tread ring supplied by the pressure source. Such methods also include inserting a tire carcass within a central opening of the tread ring while in the expanded arrangement, contracting the tread ring into an installed arrangement about an outer surface of the tire carcass, and, releasing the vacuum along the outer side of the tread ring.

  • Publication number: 20170157876
    Abstract: Particular embodiments of the invention concerns methods of forming a retreaded tire with improved tread edge area bonding, and re-treaded tires formed thereby. One embodiment of such methods includes forming an unbonded retreaded tire by arranging a pre-cured tread annularly around an annular tire carcass with a bonding layer arranged there between. The pre-cured tread includes a pair of opposing tread edges laterally-spaced to define a width of the pre-cured tread. The method also includes bonding the tread of the unbonded tire to the tire carcass to form a bonded retreaded tire by sufficiently pressurizing and heating the curing chamber to cure the bonding layer of the unbonded tire, which includes at least partially bonding a pair of laterally-spaced tread edge areas of the pre-cured tread to the tire carcass prior to an intermediate portion of the pre-cured tread located between the pair of laterally-spaced tread edge areas.

  • Publication number: 20170059748
    Abstract: Disclosed is a light diffusing panel, a light diffusing module and a traffic sign incorporating the light diffusing module. A front face of the panel has a plurality of linear disruptions, which disruptions redirect the light to emit from the front face of the panel in a broad diffuse emission. The plurality of linear disruptions extends as a series of parallel lines across the front face. A second plurality of linear disruptions extends as a series of parallel lines across the front face, with the first plurality of linear disruptions forming a grid across the front face. The light diffusing module adds to the light diffusing panel, a reflective sheet adjacent to the rear face of the light diffusing panel and light sources along an edge of the light diffusing panel. The traffic sign adds a message panel to the light diffusing module as well as a power supply.

  • Publication number: 20160354986
    Abstract: Particular embodiments of the present invention include method of forming a retreaded tire. The method includes providing an unbonded retreaded tire, forming a degassing assembly by arranging a flexible degassing membrane around an outer circumference of the unbonded retreaded tire, placing the each of the one or more vacuum chambers under at least partial vacuum pressure, and performing a degassing operation by pressurizing a degassing chamber while each of the one or more vacuum chambers in the degassing assembly are at least under partial vacuum pressure. The method further includes disassembling the degassing assembly by separating the unbonded degassed tire from the flexible degassing membrane, and bonding the unbonded degassed tire to form a bonded retreaded tire by pressurizing a curing chamber and sufficiently heating the curing chamber to cure the bonding layer of the unbonded degassed tire. A tire made by a similar process is also disclosed.

  • Patent number: 9356978
    Abstract: Systems and methods for routing activity information related to objects in an external application to activity feeds associated with users in a collaboration group are disclosed. When activity information is received, it is routed to collaboration group feeds and user feeds based on a set of routing tables. The routing tables associated objects with events, containers, collaboration groups, and finally users. Based on the routing tables, users who belong to a collaboration groups that are associated with a particular object may see the activity information about that object rendered in an activity feed if the external application grants them permission to access the object. Accordingly, security associated with the object in the external application can be maintained when event information about that object is shared in an activity feed in a collaboration system.
