Publication number: 20030197998Abstract: A power supply is filtered while the amount of in-rush current required by the capacitive charging of the filter is limited. A resistor may be placed in parallel with a relay where the parallel combination is in series with the filtering capacitor. The relay is open upon applying power to the filter and remains open while the capacitor at least partially charges to cause charging current to pass through the resistor and thereby limit in-rush current. The relay is closed thereafter to provide a short circuit around the resistor and thereby unrestrict filtering by the capacitor. Alternatively, a common mode choke is disposed between a capacitor across input nodes and a capacitor across output nodes, whereby the size of the capacitors may be reduced to limit the in-rush current due to the common mode choke. The power supply filter may be included as part of a power distribution panel.Type: ApplicationFiled: May 20, 2003Publication date: October 23, 2003Applicant: ADC Telecommunications, Inc.Inventors: Joseph Coffey, Delfino Hernandez

Patent number: 6635837Abstract: A microelectromechanical relay and a method of fabricating the same that combines electrostatic actuation with electromagnetic actuation. The relay has very low contact resistance when the relay is in its ON state and enhanced contact-to-contact isolation when the relay is in its OFF state. The relay includes a substrate having a trench formed therein, a first pair of contacts located in the trench and an actuator for controllably establishing electrical contact between the first pair of contacts. The actuator includes spaced apart supports on the substrate and a movable beam extending between the supports. A contact cross bar is located on the movable beam facing the first pair of contacts. A first electrode is located on the movable beam and a second electrode is located on the substrate.
