| 20100264935 | Electrically Conductive Kelvin Contacts For Microcircuit Tester - Terminals of a device under test are connected to corresponding contact pads or leads by a series of electrically conductive contacts. Each terminal testing connects with both a “force” contact and a “sense” contact. In one embodiment, the sense contact partially or completely laterally surrounds the force contact, so that it need not have its own resiliency. The sense contact has a forked end with prongs that extend to opposite sides of the force contact. Alternatively, the sense contact surrounds the force contact and slides laterally to match a lateral translation component of a lateral cross-section of the force contact during longitudinal compression of the force contact. Alternatively, the sense contact includes rods that have ends on opposite sides of the force contact, and extend parallel. | 10-21-2010 |

| 20090309551 | METHOD AND SYSTEM FOR DETERMINING AND CHARGING LI-ION BATTERY IN AN INTEGRATED POWER SYSTEM - A method and apparatus of determining the state of charge and charging Li-ion batteries while the batteries remain floating on the direct current (DC) bus without the need for a dedicated charger is described. The system includes a battery, a DC generator and a converter, each electrically connected to a DC bus. A charging control algorithm may be used to monitor and control the charging current supplied to the battery. The voltage on the DC bus may be varied to help control the charging current supplied to the battery, based on the battery's internal impedance and the battery's state of charge. | 12-17-2009 |
| 20110115426 | CONTROL SYSTEM FOR BATTERY CHARGE MAINTENANCE IN A POWER SYSTEM WITH MAIN AC GENERATOR CONTROL - An electrical power system may comprise an AC generator and a generator control unit (GCU) for varying AC output voltage of the AC generator. A DC bus may be connected to the AC generator via a Transformer Rectifier Unit (TRU) so that DC voltage on the DC bus is directly proportional to the AC output voltage. A battery may be connected directly to the DC bus. A control loop may be connected to receive battery current information and provide control signals to vary the AC output voltage so that battery charge may be maintained without battery damage. | 05-19-2011 |

| 20080246337 | ELECTRICAL POWER DISTRIBUTION SYSTEM AND METHOD WITH ACTIVE LOAD CONTROL - An electrical power distribution system and a method of implementation are provided. The electrical power distribution system includes: a first AC power source; a second AC power source; a first DC bus; a first AC to DC rectifier; a second AC to DC rectifier; and an electrical load management control unit. The first AC power source is connected to the first DC bus via the first AC to DC rectifier. The second AC power source is connected to the first DC bus via the second AC to DC rectifier. The electrical load management control unit shifts power extraction between the first and second AC power sources by changing an AC voltage output of one of the first and second AC power sources relative to an AC voltage output of the other of the first and second AC power sources, thereby changing an DC voltage output to the first DC bus from one of the first and second AC to DC rectifiers. | 10-09-2008 |
| 20090015063 | Method and architecture for reduction in vehicle wiring - Systems and methods perform power conversion and distribution. A system for power conversion and distribution, according to one embodiment comprises: a first generator substation ( | 01-15-2009 |
