  • Publication number: 20150193393
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for connecting to a first server to retrieve a first web page; presenting the retrieved first web page in a graphical user interface; and after receiving one or more characters in a string of characters entered into an input field of the graphical user interface, and before a submission action is received: identifying a different second web page for the string of characters; connecting to a second server to retrieve a second web page; replacing the presentation of the first web page with the second web page; after replacing the presentation, receiving one or more backspace characters entered into the input field; and in response to receiving the one or more backspace characters, replacing the presentation of the second web page with the presentation of the first web page.

  • Publication number: 20140100875
    Abstract: A system, method and program product, the system comprising: memory comprising one or more non-transitory computer-readable media comprising: a master patient database; an exchange partner database; a sub-network database; and a global identifier database storing a plurality of global identifiers; and one or more computers configured with: an inbound module for receiving incoming request data or results data from an exchange partner, including a sub-process to determine when one of a plurality of methods is identified by the incoming data, a sub-network and/or one or more responding exchange partners, a requested data type, and whether a patient is identified; a sub-process to create when the incoming data is destined for a different exchange partner, a respective communication manager sub-process for each of the one or more or responding exchange partners; an outbound request module that has a multi-level consent determination process, and a sub-process to create, by the one or more computers, a global ident

  • Publication number: 20140069124
    Abstract: Apparatus and method for treatment of a particulate material employs a conveyor belt for supporting the particulate material for transport and a source of gas for delivery through the conveyor belt to fluidize the particulate material. A gas distribution system is used for controlling the gas flow to create regions of greater and lesser fluidization. This approach avoids the use of mechanical agitation of the conveyor belt which improves efficiency and reliability. The apparatus and method fmd particular application in the handling of particulate foodstuffs in bulk when treatment such as freezing, heating, or blanching of individual food particles is required.

  • Publication number: 20130080639
    Abstract: This present invention is to classify the nodes into different roles for the purpose of routing packet and storing data. This is needed because each node in the Distributed Hash Table (DHT) network may have various capacities in terms of network bandwidth and disk storage. That is to say, this invention is focusing on assigning distinct functional roles (Server/Peer/Client) to nodes in the network based on the prior art (algorithm Kademlia). By using XOR of node ID's numeric values the distance between all the nodes can be known.

  • Patent number: 7253567
    Abstract: A low visual noise, jitterized pulse width modulation brightness control circuit is provided. The circuit uses a brightness control signal generating unit to receive a brightness adjusting signal and to generate a brightness control signal in response to the brightness adjusting signal. The brightness control pulse signal has a duty cycle or frequency varying in a predetermined range. An inverter coupled to the brightness control signal generating unit drives the fluorescent lamp in response to the brightness control pulse signal to reduce the visual interference due to the adjustment of the current beam density.

  • Publication number: 20070128383
    Abstract: A thermal transfer donor element is provided which comprises a support, a light-to-heat conversion layer, an interlayer, and a thermal transfer layer. When the above donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. The construction and process of this invention is useful in making colored images including applications such as color proofs and color filter elements.

  • Publication number: 20050122060
    Abstract: A pulse width modulation (PWM) illumination control circuit with low visual noise for driving a light-emitting diode (LED) is provided. An illumination control pulse-generating unit is used to generate an illumination control pulse signal according to an illumination-adjusting signal. The duty cycle or frequency of the illumination control pulse signal varies within a predetermined scope for controlling a DC/DC converter to drive the light-emitting diode so that overall visual noise level of the PWM illumination control circuit is improved.

  • Patent number: 6080906
    Abstract: A chemical munitions destruction system subjects the chemical agent and energetic materials to a series of treatment processes until a preselected level of destruction is achieved. The treatment processes include chemical neutralization and processing of both the chemical and energetic agents, biological treatment of the aqueous waste streams and catalytic oxidation of the air exhaust streams. In certain cases, the energetic agent and/or the propellant components of the munitions are converted to valuable chemicals by means of catalytic hydrotreating.
