| 20080270935 | SYSTEM FOR PROVIDING A CATEGORY SEPARATION IN A LIST OF DOCUMENTS - A system is provided to assist a user in selecting, identifying, and handling email messages. A selection color module may provide for the display of color coding and selection highlighting. The selection color module may provide a secondary highlighting color to indicate messages related to a selected message. A category navigation module may provide one or more of the following: an indicator that provides the user with a number of items that are off the screen for a particular category, a command that causes the first entry for a category to be scrolled into view, a label to indicate the number of items in a particular category matching a particular criteria, and/or a control for scrolling between next or previous categories. | 10-30-2008 |

| 20080290027 | METHOD AND APPARATUS FOR REMOVING SOLUTE FROM A SOLID SOLUTE-BEARING PRODUCT - The process and apparatus are for removing a solute from a solute-bearing solid product by means of a solvent which remains in liquid state throughout the entire oil extraction process. In one embodiment, the solvent is normally in gazeous state at ambient temperature and pressure values, but is used mainly in liquid state within the method and apparatus of the present invention by maintaining such pressure and temperature values within the apparatus so that the solvent will remain in this liquid state. | 11-27-2008 |

| 20100144303 | METHOD AND APPARATUS FOR REMOVING DC OFFSET IN A DIRECT CONVERSION RECEIVER - A method and apparatus for correcting direct current (DC) offset errors of a received signal in a direct conversion receiver (DCR) are provided. DC offset correction algorithms are incorporated into the DCR, each algorithm being optimized for a particular receive signal operating environment. The DC offset correction algorithms remove DC offset errors in baseband In-phase and Quadrature-phase signals received within the direct conversion receiver baseband signal path. Individual DC offset correction algorithms are selected for use as determined by a signal quality estimator component. A DC offset correction component of the direct conversion receiver determines an appropriate DC offset correction algorithm suited for a particular operating environment. A criterion for a signal quality estimate is set to control transitioning between DCOC algorithms. A dual threshold strategy may be adopted to transition between one DC offset correction algorithm and another DC offset correction algorithm to provide hysteresis. | 06-10-2010 |
| 20110026643 | CARRIER DETECT SYSTEM, APPARATUS AND METHOD THEREOF - A method of detecting an on-channel signal and synchronizing signal detection with correcting for DC offset errors in a direct conversion receiver is presented. A received signal is digitized, and a state machine operates to detect the presence of an on-channel signal. If the signal is not detected, a mixed mode training sequence is initiated in which the DC offset errors in both an analog and digital received signal path are corrected. While training, processing of the digitized samples by a digital signal processor and a host controller is suspended (while they are put into battery save mode) and the gain provided to subsequently received signals is minimized. The DC offset correction circuitry is bypassed and put into battery save mode at predetermined periods when DC offset correction is not performed. | 02-03-2011 |
