Abstract: A system for partially pre-charging an electrical power system having a high voltage power source, a DC link device with a DC Link capacitor, a low voltage power source and a DC/DC converter. In one embodiment a partial pre-charge of the DC Link capacitor can be achieved in three ways: first, through a DC/DC converter boosting from the low voltage power source, second, through a first circuit provided to charge the DC link capacitor to a partial pre-charge state using the voltage directly from the low voltage power source, and third, through a second circuit provided to limit current flowing to the DC link capacitor from the high voltage power source to charge the DC Link capacitor only to a partial pre-charge level.

Abstract: An example system for testing a device under test (DUT) includes one or more processing devices configured to receive first data from the DUT over a communication channel, and to analyze the first data to identify an error associated with the communication channel; and a power supply controller configured to receive second data based on a power disturbance from the DUT, and to compare the first data and the second data to determine if there is a correlation between the power disturbance and the error.

Abstract: Systems for efficiently starting an engine of a hybrid electric vehicle are provided. An example of a system comprises a first processor and a second processor. The second processor is configured to determine when to start an internal combustion engine, cause energy to be supplied from an energy storage device to a generator/motor to cause the generator/motor and crankshaft to rotate to at least a hold speed, transmit a first instruction to a first processor when determining that the internal combination engine should be started. The first processor does not supply fuel to at least one cylinder of the internal combustion engine in response to the first instruction. The second processor is configured to transmit a second instruction to the first processor after a variable period of time has elapse after the generator/motor or crankshaft has reached at least the hold speed.

Abstract: A ceramic package substrate has a recess. This allows a device in that recess to be close to a die attached to the substrate's top side, for better performance. The device may be an array capacitor, an in-silicon voltage regulator, or another device or devices.

Abstract: A protective apparatus is disclosed. The apparatus includes a protective element for positioning over at least a portion of a device to protect the device in a first configuration. A support structure integral with the protective element also forms part of the apparatus. The support structure is configured to support the device in a second configuration. In one arrangement, the protective element includes a first surface and a second surface in which the first surface is configured to be at least partially positioned over and to face the device in the first configuration. The second surface is positioned opposite to the first surface and is configured to be exposed to the environment external to the device in the first configuration. In another arrangement, the support structure includes a slot that runs along the second surface in which the slot is configured to receive the device in the second configuration.

Abstract: A method of facilitating wireless communications between a load controller device and a network component is described. The method can include the step of transitioning the load controller device from a peer-to-peer state in which the load controller device can receive initialization information to a provisioned state in which the load controller device connects to the network component using the initialization information. If there is a disruption in the connection between the load controller device and the network component in the provisioned state, the load controller device can be forced back to the peer-to-peer state from the provisioned state to enable the load controller device to receive new initialization information for reestablishment of the connection between the load controller device and the network component or for establishment of another connection between the load controller device and a different network component.
