20110303400 | COUNTERFLOW HEAT EXCHANGER - A counterflow heat exchanger having a plurality of heat exchanger elements in a stacked, spaced-apart arrangement forming a plurality of inter-element passages. Each element has fluid passages formed between facing sections of a first plate and a second plate. A first-fluid passage has an outer passage circumscribing an inner passage in fluid communication with the outer passage. An inlet-port traversing passage in fluid communication with the outer passage, an outlet-port traversing passage in fluid communication with the inner passage and a second-fluid traversing passage circumscribed by the inner passage traverse the first and second plates. A first-fluid inlet header includes the inlet-port traversing passage of each element. A first-fluid outlet header includes the outlet-port traversing passage of each element. A second-fluid inlet passage in fluid communication with the plurality of inter-element passages includes the second-fluid traversing passage of each element. | 12-15-2011 |

20160073500 | Decoupling Capacitive Arrangement to Manage Power Integrity - Various implementations disclosed herein include arrangements that reduce parasitic inductance associated with a discrete decoupling capacitor by using a three-terminal capacitor and a staggered array of power supply and ground connections. In some implementations, a capacitive decoupling arrangement includes a substrate, an array of electrical vias of first and second types, and a capacitive arrangement on one side of the substrate coupled to the array of electrical vias. The array of electrical vias includes a first type of vias and a second type of vias. The capacitive arrangement is coupled between two respective vias of the first type of vias and two respective vias of the second type of vias on the first planar surface of the substrate. The capacitive arrangement includes a plurality of capacitive elements electrically arranged in parallel between the two respective vias of the first type of vias and the two respective vias of the second type of vias. | 03-10-2016 |

20140118962 | Current Redistribution in a Printed Circuit Board - In one implementation, a multilayered printed circuit board is configured to redirect current distribution. The current may be distributed by steering, blocking, or otherwise manipulating current flows. The multilayered printed circuit board includes at least one power plane layer. The power plane layer does not distribute current evenly. Instead, the power plane layer includes multiple patterns with different resistances. The patterns may include a hatching pattern, a grid pattern, a directional pattern, a slot, a void, or a continuous pattern. The pattern is a predetermined spatial variation such that current flows in a first area differently than current flows in a second area. | 05-01-2014 |

20090047829 | UNSHIELDED RJ STYLE CONNECTOR TO ELIMINATE CABLE ELECTROSTATIC DISCHARGE EVENTS - In one embodiment, an apparatus includes at least one signal contact, a housing, and a discharge circuit arrangement. The housing defines a receptacle configured to receive a part of a cable assembly. The signal contact is disposed within the receptacle, and is configured to contact a first contact of the cable assembly when the cable assembly is received in the receptacle such that a signal may pass between the at least one signal contact and the first contact. The discharge circuit arrangement is at least partially disposed on the housing, and includes at least one discharge conductor that contacts the first contact and discharges an electrical charge associated with the first contact through a discharge circuit before the first contact contacts the signal contact. | 02-19-2009 |
