摘要:
The system and method for providing a composite image corresponding to a textual message. The composite image is generated by receiving a text message, parsing out styling information, using predetermined size and spacing for combinations of typographical characters in combinations with a graphics editing routine which allows for the recognition and translation of text into a series of images which can then be presented to a viewer as a composite image.
摘要:
A signal driver having a selectable aggregate slew rate, a method of driving a signal driver and a signal driver incorporating the driver or the method. The driver includes plural partial drivers configured to output signals based on time constants established by corresponding plural time-delay networks associated therewith. The signal driver further includes a slew rate selector coupled to the plural time-delay networks and configured to provide a common signal thereto to cause the plural time-delay networks to achieve target time constants, the target time constants causing the output signals to be generated such that the signal driver achieves the selectable aggregate slew rate.
摘要:
A unitized multilayer circuit structure that includes a plurality of planar dielectric insulating layers stacked in laminar fashion to form a substrate having sides formed by edges of the dielectric insulating layers and recessed regions formed in one or more one sides of the substrate for use in attaching the unitized multilayer circuit structure to a higher level assembly or for attaching electrical contact circuitry to the unitized multilayer circuit structure.

摘要:
A transmission line structure including a central signal conductor stack of elongated conductive strips separated from each other by contiguous dielectric layers of a unitized multilayer circuit structure, a first ground conductor stack of elongated conductive strips separated from each other by contiguous dielectric layers and laterally separated from one side of the central signal conductor stack, and a second ground conductor stack of elongated conductive strips separated from each other by contiguous dielectric layers and laterally separated from another side of the central signal conductor stack such that the central conductor stack is laterally between the first and second ground conductor stacks.
摘要:
A polymer composition comprising (1) a polyether polyol which is a product obtained by the free radical addition of a fluoro-olefin of the general formula: ##STR1## wherein Y represents F or fluoroalkyl and Z represents Cl or F(CF.sub.2)m--wherein m is an integer from 0 to 10 or Y and Z together form a (CH.sub.2)p--chain wherein p represents an integer from 2 to 4, to a polytetramethylene gylcol having a molecular weight in the range 162 to 5000 and (2) at least one acrylic polymer. The composition is useful for coating compositions or for the fabrication of films.
摘要:
A semiconductor device includes a substrate configured with a plurality of conductive traces. The traces are configured to electrically couple to an integrated circuit (IC) die and at least one of the plurality of conductive traces includes first electrically conductive portions in a first electrically conductive layer of the substrate, second electrically conductive portions in a second electrically conductive layer of the substrate, and first electrically conductive connections between the first electrically conductive portions and the second electrically conductive portions. The first and second electrically conductive portions and the first electrically conductive connections form a continuous path along at least a portion of the at least one of the conductive traces. Time delay of conducting a signal along the at least one of the conductive traces is within a specified amount of time of time delay of conducting a signal along another one of the plurality of conductive traces.
