20130207555 | LED DRIVER SYSTEM WITH DIMMER DETECTION - An LED driver system including an input receiving a rectified AC conductive angle modulated voltage on a rectified node, a converter, a low-pass filter, and AC detector, and a driver network. The converter is to the rectified node and includes a power switching device coupled to a switching node, in which the power switching device is controlled to convert the rectified AC conductive angle modulated voltage to an output voltage and output current. The low-pass filter is configured to filter voltage of the switching node to provide a filtered voltage. The AC detector receives the filtered voltage and provides a current sense signal indicative thereof. The driver network controls duty cycle of the power switching device based on the current sense signal. | 08-15-2013 |

20090033422 | Multi-level slew and swing control buffer - A buffer amplifier and an associated method have been provided for slew rate and swing level control in the buffering of a signal. The method accepts an input signal having a voltage swing, a swing control signal, and a slew rate control signal. The voltage swing for each output in a set of serially-connected buffer stages is selected in response to the swing control signal. The selected voltage swing for a subset of buffer stages is modified in response to the slew rate control signal. Selecting the voltage swing for each output entails selecting a source current for each buffer stage. A bias current is generated and mirrored through a current source connected to each buffer stage. Modifying the selected voltage swing for each of the subset of buffer stages includes modifying the bias current to the subset of buffer stages. | 02-05-2009 |

20150365274 | LIVE PARTITION MOBILITY WITH SHARED PERSISTENT RESERVATIONS - According to one embodiment of the present invention, a method is provided. The method may include a computer registering a first instance of a logical partition on a source server with a logical unit and placing a first persistent reservation on the logical unit, wherein the first persistent reservation indicates that only the first instance of the logical partition can hold a reservation on the logical unit. The method may further include the computer registering a second instance of the logical partition on a destination server with the logical unit and downgrading the first persistent reservation, such that the first and second instances of the logical partition can hold persistent reservations on the logical unit. The method may further include the computer placing, by one or more computer processors, a second persistent reservation on the logical unit. | 12-17-2015 |

20110161344 | ENHANCING SOFT FILE SYSTEM LINKS - A method for determining whether a soft link of a target file is pointing to a correct file system is provided. A unique identification number for a mounted file system is retrieved from a storage device in response to receiving a request to access a target file in the mounted file system. In addition, an identification number is retrieved from a soft link of the target file in response to accessing the soft link of the target file in the storage device. Then, it is determined whether a match exists between the unique identification number for the mounted file system and the identification number from the soft link of the target file. In response to determining that a match does exist between the unique identification number for the mounted file system and the identification number from the soft link of the target file, access to the target file is allowed. | 06-30-2011 |
