  • Patent number: 7901485
    Abstract: Vortex gas separation is forced in radial counterflow between counter-rotating coaxial centrifugal impellers. Feed is at the axis of rotation. Axial extraction of nitrogen and water vapor is driven by an axial pump and by back pressure from the tank while radially outward flow of carbon dioxide and scrubbing targets is driven by the impellers. Scrubbing of the concentrated targets is in high turbulence during a long residence time. Tiny centrifugation effects of innumerable turbulent eddy vortices in a shear layer between the impellers and in the tank are integrated by the forcing regime of the impellers and the axial pump. Radial vortices caused by shear between the counter-rotating impellers provide coherent sink flow conduits for axial extraction of nitrogen ballast. Fine fly ash (PM-2.5) scrubbing is concurrent with NOx and SOx scrubbing and with carbon capture.

  • Patent number: 7898705
    Abstract: A method to determine the color status of a scanned original segments a binary halftone image into a predetermined number of local windows and converts each local window to a device-independent color space. The method then determines a color space parameter for each local window and compares the color space parameters for the local windows to at least one threshold to determine the color status of the scanned original. An apparatus having a scanner creates a scanned image of an original and has at least one processor to create a binary halftone image from the scanned image, segment the binary halftone image into a predetermined number of local windows, convert each local window to a device-independent color space, determine a color space parameter for each local window, and compare the color space parameter for each local window to at least one threshold to determine the color status for the scanned original.

  • Patent number: 7894597
    Abstract: The present invention provides a mechanism for categorizing telephone calls and for providing special information about calls that appear on call lists maintained in a telephone. The invention provides for both providing an indication and for providing an action. When an entry on a call list is highlighted (in a conventional manner), pressing one key adds a flag to the entry on the call list to indicate that follow up action is required. Pressing a second key initiates an action such as attaching a reminder so that the user will be reminded to take action later. Pressing a third key will provide a text message balloon indicating information about the call. The flags and text messages can be added by either the called party or the calling party.

  • Patent number: 7885396
    Abstract: A method and system for providing a user who places a telephone call on hold with a partial hold option. When a user places a first call on partial hold and picks up a second call, the user can still hear conversation and activity that occurs on the first call. For example a user participating in a conference call may receive a second call. The user can place the conference call on partial hold and pick up a second call (i.e. engage in a conversation on a second telephone call). However, the incoming channel to the conference call will remain active and the user will be able to hear, in the background, what is taking place in the conference call. Should the user hear something interesting in the conference call, or if the user hears someone ask a question directed to the particular use, the user can switch back to the conference call.

  • Patent number: 7886051
    Abstract: A method for tracking and reporting traffic activity on a web site first comprises storing a web page on a first server coupled to a network. When the web page is requested from a visitor computer, the visitor computer is selected (or not selected) for inclusion within a sample group, where the sample group is only a subset of the total traffic to the web site. A selection indicator is stored on the visitor computer associated with this selection. Data mining code within the web site is operated or not operated depending upon the value of the selection indicator. The data mining code is operated, and the activity of the visitor computer on the web site consequently tracked only if the visitor computer is selected as a member within the sample group, otherwise the data mining code is not operated and no traffic activity is generated.

  • Patent number: 7880818
    Abstract: We describe a device and an associated method that includes an EHT signal processing module to generate a compensated gain signal responsive to a first EHT signal. A field fly-back processing module generates a first correcting signal responsive to a first VFB signal. A horizontal scanning correction module generates a predistortion signal responsive to the compensated gain signal. A first digital to analog conversion module converts the predistortion signal into a corresponding analog predistortion signal. A field scanning correction module generates a correcting wave responsive to the compensated gain signal and the first correcting signal. A pulse width modulated module generates a modulated correcting wave by pulse width modulating the correcting wave. A power amplification module generates an amplified modulated correcting wave by amplifying the modulated correcting wave. And a cathode ray tube displays an image responsive to the analog predistortion signal and the amplified modulated correcting wave.

  • Patent number: 7872272
    Abstract: A structure and method for improving UV LED efficiency is described. The structure utilizes a tunnel junction to separate a P-doped layer of the LED from a n-doped contact layer. The n-doped contact layer allows the use of a highly reflective, low work function metal, such as aluminum, for the p-side contact. The reflectivity at the contact can be further improved by including a phase matching layer in some areas between the contact metal (The metal above the phase matching layer does not necessarily need to have a low work function because it does need to form an ohmic contact with the n-contact layer) and the n-doped contact layer.
