| 20120063315 | Method for Congestion Avoidance in 4G Networks - This invention aims to avoid and resolve congestions in wireless 4G networks. The method is based on a central self-organizing network (SON) server, which dynamically changes neighbor lists on congested base station and on all base stations in vicinity. The procedure is triggered by measuring relative committed traffic rate and air interface utilization of the base station. When base station enters into congested state, it notifies the SON server. The SON server creates new neighbor lists for all base stations in the vicinity and removes the congested base station from these lists. With new neighbor lists propagated to mobile stations, the latter won't scan and initiate handovers to the congested base station. The SON server additionally creates a new dense neighbor list and changes handover triggers settings of the congested base station. The mobile stations consequently find other handover opportunities and connect to different base stations. As the air interface resources are released, the base station leaves the congested state. | 03-15-2012 |
| 20120064832 | Method for 4G Node Frequency Selection - A method for 4G node frequency selection describes a mechanism for automatically selecting the frequency of a newly installed base station, thereby optimizing the throughput per area unit of the newly installed base station in its predefined vicinity area. The method is based on an iterative calculation approach which combines real-world network and base station measurements information with the nominal specifications of the newly installed base station (antenna diagram, output power) and the location and direction thereof. | 03-15-2012 |
| 20120083279 | Method for Cognitive 4G Neighborhood Selection - A method for cognitive neighbor selection in 4G networks describes a mechanism for automatic self-learning selection of neighboring base stations for the purpose of providing seamless handoffs in a dense deployment of pico and macro base stations. When a 4G network is modified by adding new base stations, the optimum handoff thresholds and advertised base station neighbors are automatically recalculated in a manner that reduces the number of unnecessary handoffs in a dense network with large number of pico and macro base stations. | 04-05-2012 |

| 20100172575 | Method Of Detecting Red-Eye Objects In Digital Images Using Color, Structural, And Geometric Characteristics - Disclosed are methods, devices, and computer program products for red-eye detection in a digital image. In one example embodiment, a method for detecting a red-eye effect in a digital image includes several acts. First, red pixels having a predetermined degree of redness are identified in the image. Next, redness contrast is detected with respect to each of the red pixels and redness is then enhanced for those red pixels having a predetermined level of redness contrast. The pixels identified as being red are then further refined by applying another redness threshold based on one or more color characteristics associated with the red pixels. The refined set of red pixels may then be partitioned into a set of one or more candidate red-eye objects. A candidate red-eye object may be removed as a false positive based on geometric constraints associated with red-eye objects and/or proximity of the object to pixels with human skin-like color tones. | 07-08-2010 |
| 20100172584 | Method Of Classifying Red-Eye Objects Using Feature Extraction And Classifiers - Disclosed are methods, devices, and computer program products for red-eye detection in an image. In one example embodiment, a method for detecting red-eye objects in an image includes several acts. First, a set of candidate red-eye objects identified in the image is received. Then, features are extracted from the candidate red-eye objects and, with a plurality of classifiers, a false red-eye object is eliminated from the set of candidate red-eye objects based on the extracted features. First and second ones of the plurality of classifiers are optimized for classifying objects in a first range of sizes using first and second ones of the extracted features, respectively. Furthermore, third and fourth ones of the plurality of classifiers are also optimized for classifying objects using the first and second ones of the extracted features, respectively, but for objects in a second range of sizes. | 07-08-2010 |

| 20110109574 | Touch-Based User Interface Touch Sensor Power - An apparatus having a touch sensor able to detect the touch of a tip of a digit of a user, having a conductive ring able to detect the approach of the tip towards the touch sensor, having a motion sensor to sense movement of a casing the apparatus, and having components of a controller to place the apparatus in one of a lower power mode after a predetermined period of inactivity has elapsed, a partial power mode in response to an indication of the approach of a tip of a digit, and a higher power state to detect touching of the touch sensor by a tip of a digit. Other forms of proximity detectors may be employed in place of the conductive ring, or the conductive ring may be replaced by one or more elongate conductors positioned about one or more sides of the periphery of a touch-sensitive surface of the touch sensor. | 05-12-2011 |
| 20110109586 | Touch-Based User Interface Conductive Rings - An apparatus in which an outer conductive ring surrounds the periphery of a touch-sensitive surface of a touch sensor serving as a manually-operable control, wherein a portion of the outer conductive ring is also between the touch-sensitive surface and another manually-operable control that lacks the ability to sense the mere touch of a tip of a digit of a user. A processing device causes the level of capacitance of the outer conductive ring to be measured on a recurring basis for instances of an amount of additional capacitance above a minimum capacitance threshold, and employs such amounts of additional capacitance in a comparison to distinguish between the user interacting with a control surface defined on the touch-sensitive surface of the touch sensor or the other manually-operable control. | 05-12-2011 |
