Abstract:

Configurable communications modules and methods of making the same are described. In one aspect, a communications module includes a data channel and a termination impedance controller. The data channel is operable to translate data signals in at least one direction between a transmission cable interface and a host device interface. The data channel has a variably configurable termination impedance at a host device node that is connectable to a host device. The termination impedance controller is operable to set the variably configurable termination impedance of the data channel to match the termination impedance to the host system.

Abstract:

Nets of a logic design are efficiently routed in a programmable logic device, which includes multiple types of programmable interconnects. Patterns are read from a library in a storage device. Each pattern includes an ordered set of the types of the programmable interconnects. A path is determined from the source to the destination for each net of the logic design. The path is through a sequence of the programmable interconnects having types that correspond to each type in the ordered set of a selected pattern. A description is output of the path for each of the nets.

G06F 7/16

US Classification:

707602, 707752

Abstract:

A computer readable storage medium includes executable instructions to analyze sort options associated with an input table and a comparison table. It is determined whether a consistent sort can be performed by a first database associated with the input table and a second database associated with the comparison table. A first sort operation is performed on the input table at the first database and a second sort operation is performed on the comparison table at the second database when a consistent sort can be achieved. Sort operations on the input table and the comparison table are executed at a common sort engine when a consistent sort cannot be performed by the first database and the second database.

Abstract:

The invention provides a device, system, and method for isolating one or more sample components of a sample material following separation of the sample material into a plurality of sample components. The device includes first and second pinching channels, a separation channel extending between the first and second pinching channels, a collection leg that includes a collection well, and a waste leg, all of which are in fluid communication with a switching region. In the method, a sample material is separated into a plurality of separated components in the device. and one or more of the separated components are isolated in the collection well. The separated components are constrained and elongated in the switching region by first and second buffer streams.

Abstract:

A parallel optical communications device is provided that has an OSA that includes at least one heat dissipation block having a slot formed in a lower surface thereof that contains a weldable insert. Likewise, an upper surface of the mounting device of the ESA has at least one slot formed therein that contains a weldable insert. After the OSA is placed in contact with the ESA and optically aligned with the ESA, the OSA is secured to the upper surface of the mounting device of the ESA by welding together the respective weldable inserts contained in the respective slots in the OSA and in the mounting device of the ESA. The welding process results in an extremely strong welded joint between the OSA and the ESA that prevents relative movement between the OSA and the ESA if external forces that are exerted on the OSA and/or on the ESA.

Abstract:

A coverage evaluator determine search results that are a subset of potential search results, the search results provided in response to search requests, wherein a covered portion of the potential search results are associated with quick review information and a non-covered portion of the potential search results are not associated with quick review information. A coverage calculator may calculate a coverage of search results, based on a relation of covered, weighted impressions of the covered portion to weighted impressions, wherein the weighted impressions include non-covered, weighted impressions of the non-covered portion, if any.

Abstract:

Disclosed are methods and systems for providing a constraint-driven environment for implementing a physical design of an electronic circuit with automatic snapping. In some embodiments, the method identifies or creates an incomplete layout. The method identifies an object and constraints for the object. The method then identifies an approximate position for the object in the layout and automatically snaps the object to a drop location based on the approximate position while complying with relevant constraint(s). The method may further align an object with another object with some spacing in between in some embodiments. The method may also perform automatic layer-to-layer snapping between two sets of objects such as cell instances, each having at least one object on multiple layers.
