20110039679 | Wet cyclone particle collector - A wet cyclone particle collector is disclosed. The wet cyclone particle collector includes a cyclone unit, a liquid delivery unit and a sample collection unit. The cyclone unit draws a gas sample into a cyclone chamber and creates a circular flow of the gas sample inside the cyclone chamber so that particles in the gas sample are separated from said gas sample by centrifugation force. The liquid delivery unit delivers a collection liquid into the cyclone in a non-continuous fashion. The sample collection unit harvests the collection liquid from the cyclone unit. The non-continuous delivery of the collection liquid significantly reduces consumption of collection liquid during operation of the particle collector. | 02-17-2011 |

20150199520 | MEDIATED SECURE BOOT FOR SINGLE OR MULTICORE PROCESSORS - A system and methods are disclosed for securely booting a processing system using a three step secure booting process. Several embodiments are presented, wherein upon power-on-reset, the first boot step uses a secure boot device comprising of a programmable device or an FPGA which boots up first, validates its configuration file and then validates the processor(s) configuration data before presenting the configuration data to the processor(s). This enables validation of ‘pre-boot’ information, such as the Reset Control Word and pre-boot processor configuration data. The second and third boot steps validate the internal secure boot code and external boot code respectively using one or more of secure validation techniques, such as encryption/decryption, Key mechanisms, privilege checking, pointer hashing or signature correlation schemes. This results in an end-to-end secure boot process for a variety of architectures, such as single processor systems, synchronous and asynchronous multiprocessing systems, single core systems and multi-core processing systems. | 07-16-2015 |

20110112666 | System and Method for Interfacing an Audio Connector and Jack at an Information Handling System - An analog connector disposed at an information handling system housing accepts both analog audio information and digital audio information at plural connection surfaces by accepting either an analog or digital jack. An audio subsystem of the information handling system manages audio information at the connector by selectively configuring to handle analog or digital signals based upon the type of jack insert into the connector. Selection of analog or digital management is performed manually through a user interface or automatically by detection of the type of jack inserted in the connector. In one embodiment, a four pole analog connector accepts a four pole digital jack that communicates serial data through a pole connection surface instead of analog signals. | 05-12-2011 |

20090319325 | TRANSFERRING A DIGITAL IMAGE FROM A PHOTOGRAPHER TO A FULFILLMENT CENTER TO GENERATE A PHOTOGRAPHIC PROCESS - A photographer computing device is described. The device receives information that specifies option(s) to create a photographic product from a digital image; a list of fulfillment center(s) to generate the product according to the options, and routing information to at least one of the center(s). The device transmits an order for the product to at least one center. The order specifies a method (e.g., at will or within a specified or negotiated period of time) for the device to communicate the image to selected ones of the center(s). The delivery method is independent of receipt of any type of request or prompt for the image from any other computing device including the gateway device and any fulfillment center. The device uploads the image as per the delivery technique and receives confirmation that the order has been received. | 12-24-2009 |

20150364993 | BOOST CONVERTER STAGE SWITCH CONTROLLER - A low voltage lamp includes a boost converter stage and a load. The load may include low voltage light producing elements including low voltage light emitting diodes. The boost converter stage receives an electronic transformer output and includes an inductor coupled to a switch and a switch controller that receives one or more controller inputs. Inductor current may be returned to the transformer when the switch is closed and provided to a rectifier coupled to the load when the switch is open. Controller inputs may include a transformer input that receives the transformer output, a sense input indicating switch current, and a load input indicating load voltage. Controller logic may synchronize assertions of a control signal for the switch with edge transitions of the transformer output to maintain peak inductor current within a specified range and to selectively transfer stored energy in the inductor to the load or back to the transformer. | 12-17-2015 |

20130247185 | SYSTEMS AND METHODS FOR TRACKING AND RECORDING EVENTS IN A NETWORK OF COMPUTING SYSTEMS - A security client can be configured to operate on the one or more computing systems and record all events occurring on the one or more computing systems. The security client can operate as a “security camera” for the computing systems by identifying and retaining data and information that describes and details different events that occur on the computing systems. The security client can be configured to generate event records for the events that are uniquely associated with the process that requested or performed event. Likewise, the security client can be configured to uniquely associate the event records with the specific computing system associated with the event. | 09-19-2013 |

20120239298 | Geological Stress Inversion Using Fault Displacement and Slip Tendency - A computer-implemented method of determining the stress state associated with a geological fault is described. The source data comprises measured fault displacement values, or proxy displacement values, associated with the fault. An error function calculates error as a function of normalized fault displacement and normalized slip tendency. Candidate stress states are used to determine slip tendency values, which are used in the error function to calculate an error value. This value is minimized to determine the “best” candidate stress state. | 09-20-2012 |
