Abstract:
Systems and methods for implementing customized drop-down menus in user interface displays. Drop-down menus include one or more selection options and a table having multiple fields. Drop-down menu items are particularly useful for assisting a user with assigning information synchronized into a target database from one database system, such as an Outlook file, to objects in the target database system, such as a multi-tenant database system as well as providing suggestions to the user from search results when they may want to choose one of those results or perform a different action altogether.

Methods and systems are provided for associating objects in a database. An exemplary method involves identifying one or more objects in the database that are likely to be related to a first object in the database that is based on data obtained from a local application associated with a user and displaying the identified objects on a client device associated with the user. In exemplary embodiments, the identified objects are displayed in response to selection of a graphical user interface element enabling indication of a second object from among the one or more objects, wherein the first object is associated with the second object in the database after receiving indication of the second object. In one or more exemplary embodiments, the database is a multi-tenant database in a multi-tenant system providing instances of a virtual application to multiple tenants.
Abstract:
A method and system for reducing via hole parasitic effects on PCB transmission channels. In order to reduce the effects of excess via capacitance in PCB structures, PCB via modeling accuracy for high speed serial data transmissions is improved by utilizing lower permittivity reinforcement and z-axis conducting methods. A method to accomplish this includes creating a channel within the circuit board to accommodate a via hole, filling the created channel with a predetermined amount of dielectric material, forming the via hole, and electrically coupling the top layer of the structure to at least an inner signal substrate layer of the structure.
Abstract:
Inner layer traces on a multilayer printed wiring board are exposed to enable direct interconnection with another device such as a printed wiring board. The traces may be exposed by removing at least some of the dielectric substrate material around the traces, or by extending the traces beyond the other layers of the printed wiring board. Corresponding conductors associated with the other device are placed in direct physical contact with the exposed inner layer traces, and may be aligned and secured with guide plates, alignment pins and spring members. Such direct connection mitigates the need for vias, and has more favorable electrical characteristics for high frequency signal transmission.
Abstract:
A printed circuit board transmission line has an outer conductive wall surrounding an inner dielectric core. The transmission line may be disposed inside a grounded shielding to provide a form of coaxial conductor that mitigates cross talk from adjacent transmission lines and EMI. Further, groups of dielectric-core transmission lines may be disposed within a single grounded shield. For example, edge coupled differential pairs may be disposed in parallel with each other on a plane defined by a layer of the printed circuit board, i.e., side-by-side. Further, broadside-coupled differential pairs of dielectric-core transmission lines may be disposed in parallel with each other in a stack which is orthogonal with the plane defined by a layer of the printed circuit board, i.e., one on top of the other. Further, a plurality of dielectric-core transmission lines which may include all or ones of single-ended lines and differential pairs may be disposed within a single grounded shield.

A technique for facilitating signal transmission at high signal frequencies in a multi-layer substrate is disclosed. In one embodiment a multi-layer substrate comprises a conductor or pair of conductors, a first dielectric layer on a first side of the conductor or pair of conductors and a second dielectric layer on a second side of the conductor or pair of conductors. An air channel is provided in the first dielectric layer, the air channel formed to be substantially coextensive with the conductor or pair of conductors. A conductive shield surrounds the conductor or pair of conductors, the first dielectric layer, and the second dielectric layer in order to eliminate crosstalk. The conductor or pair of conductors may have discrete spaced edges and the width of the conductor or pair of conductors may be increased in order to adjust the impedance because of the low dielectric constant of air. Furthermore, additional air channels and a supporting layer may be included in the structure.
