20110285911 | CONTRAST CONTROL DEVICE AND METHOD THEREFOR - A first video picture is translated based upon a first translation matrix to adjust a contrast of the first video image. A second translation matrix is determined based upon a first histogram of a second video picture. A third translation matrix is determined based upon the first translation matrix and the second translation matrix, and the video picture is translated based upon the third translation matrix. The translation matrix can be determined using a histogram that has been adjusted using a clipped histogram equalization technique. | 11-24-2011 |

20110199537 | METHOD AND/OR APPARATUS FOR IMPLEMENTING A COLOR MANAGEMENT MODULE - An apparatus comprising a first circuit, a processing circuit and a conversion circuit. The first circuit may be configured to generate a first intermediate signal in a second format in response to an input signal in a first format. The processing circuit may be configured to generate a second intermediate signal and a third intermediate signal in response to the first intermediate signal. The conversion circuit may be configured to generate an output signal in the first format in response to the second intermediate signal and the third intermediate signal. The processing circuit may be configured to implement color blending on the second intermediate signal in the second format prior to conversion to the first format and pass the third intermediate signal without color blending. | 08-18-2011 |

20100107623 | HYDRAULIC SYSTEM HAVING AN EXTERNAL PRESSURE COMPENSATOR - A hydraulic system for a machine is disclosed. The hydraulic system has a source of pressurized fluid and a fluid actuator with a first chamber. The hydraulic system also has a first valve configured to selectively fluidly communicate the source with the first chamber. The first valve further includes a first element movable between a flow passing, at which fluid from the source flows to the first chamber, and a flow blocking position, at which fluid from the source is blocked from the first chamber and a second element configured to selectively drain a control passageway associated with the first element to cause the first element to move. The hydraulic system further has a proportional pressure compensating valve configured to control a pressure of a fluid directed between the source and the first valve dependent upon the pressure of the control passageway. | 05-06-2010 |
20110072809 | HYDRAULIC SYSTEM AND METHOD FOR CONTROL - A hydraulic system is disclosed having at least two hydraulic circuits. The disclosed system apportions flow between the two hydraulic circuits based on an assumed flow rate that is held constant in both power-limited and non-power-limited conditions. | 03-31-2011 |
20110302998 | METHOD AND SYSTEM FOR COMPACTION MEASUREMENT - A system for compaction measurement, including at least two compaction measurement systems for determining the compaction state of various portions of a material region at a worksite and a display system for displaying aggregated data from the compaction measurement systems. | 12-15-2011 |
20130136535 | PAVING SYSTEM UTILIZING CAPSULES ENCLOSING A DYE - A method of controlling a paving process is disclosed. The method may include mixing at least one capsule that at least partially encloses a dye within a paving material and dispensing the paving material at a desired location. The method may also include performing a compacting process on the paving material and monitoring for a presence of the dye at a surface of dispensed paving material. The method may further include controlling the compacting process based on the presence of the dye. | 05-30-2013 |
20140034135 | HYDRAULIC SYSTEM WITH A DYNAMIC SEAL - A system can include one or more valve arrangements with a working chamber to receive a working fluid at a first pressure, and a control chamber to receive fluid at a second pressure. A dynamic seal can be disposed on a land of a valve element. The valve arrangement may include a sleeve against which the dynamic seal is slidably engaged. The valve element may include a check stem. A pressure compensating system may be in communication with bores formed in with the valve element. A pressure system to monitor dynamic seal wear may be in communication with the control chamber of the valve arrangement. | 02-06-2014 |

20150184680 | Torque Limit Control - A prime mover transfers power to a separate hydraulic circuits via a power take off (PTO). In some situations, a peak torque demand in one of the hydraulic circuits may cause the total torque of all hydraulic circuits to exceed a rated torque at the PTO. An apparatus measures hydraulic fluid pressure in a first hydraulic circuit and adjusts the hydraulic fluid pressure in a second hydraulic circuit. Because pressure is directly correlated to torque at a pump, by adjusting the pressure in the second circuit based on the current pressure in the first hydraulic circuit, the total torque may be capped below the maximum torque rating at the PTO. The first hydraulic circuit may have a higher priority function, such as steering, compared to that of the second hydraulic circuit which may, for example, power a tool. | 07-02-2015 |
