Patent number: 6803252Abstract: Methods and apparatus for providing connection packages for high-speed integrated circuits (“ICs”) in optical, electronic, wired or wireless communications are disclosed. The connection package achieves dimensional transformation of signal routes from high-speed, high-density IC's input/output pads to the external terminals such as coaxial terminals and BGA balls, while maintaining constant characteristic impedance throughout the transmission lines. A package may include a substrate having microstrips for communicating signals between the IC pads and external terminals. A pair of differential microstrips can be positioned closer to each other near the IC pads and create capacitive coupling. Such coupled capacitance allows the width of the microstrips to be reduced.Type: GrantFiled: November 21, 2001Date of Patent: October 12, 2004Assignee: Sierra Monolithics, Inc.Inventors: Binneg Y.

Patent number: 6560085Abstract: An apparatus and method for interrupting the flow of electrical current in a line is disclosed. The invention provides for better limitation of current than can be achieved in the prior art. With effective current limitation, the magnetic force generated by the circuit breaker coil will not be excessive thereby reducing potential damage to the circuit breaker armature, increasing the interruption rating of the circuit breaker and end-use equipment and decreasing the interruption pressure within the circuit breaker.Type: GrantFiled: December 20, 1999Date of Patent: May 6, 2003Assignee: Square D CompanyInventors: William W.

Publication number: 20020196592Abstract: The present invention provides a transformer having a positive temperature coefficient resistivity polymer element electrically coupled to either the primary or secondary winding of the transformer to provide protection against overcurrent, short circuit and thermal overheating conditions. Use of the positive temperature coefficient resistivity polymer element helps to further reduce the amount of space needed for electrical and thermal protection of the transformer while lowering manufacturing costs by eliminating the use of a fuse and fuse block. The positive temperature coefficient resistivity polymer element also provides an advantage to the end user in that the positive temperature coefficient resistivity polymer element does not require replacement, unlike prior art fuses, following an overcurrent, short circuit or thermal overheating event.Type: ApplicationFiled: June 20, 2001Publication date: December 26, 2002Inventors: William W.
