20100128652 | METHODS AND SYSTEMS FOR PERFORMING HARQ ACK WITH SCANNING AND SLEEP IN WIMAX SYSTEMS - Embodiments of the present disclosure provide techniques for processing a HARQ data burst and/or a HARQ ACK message in the event a HARQ ACK message falls within a scanning or an unavailable interval of an MS. For certain embodiments, a HARQ ACK message may be postponed if it falls within the scanning or the unavailable interval of the mobile station. For certain embodiments, the HARQ data burst transmission may be postponed if the corresponding HARQ ACK message falls within a scanning or an unavailable interval of the mobile station. For certain embodiments, the HARQ ACK may be transmitted or received even if it falls within the scanning or the unavailable interval of the mobile station. However, the HARQ ACK message may not be processed during the scanning/unavailable interval. | 05-27-2010 |
20100146359 | METHODS AND SYSTEMS FOR ARQ FEEDBACK MESSAGE IMPROVEMENT - Certain embodiments of the present disclosure propose techniques for improving automatic repeat request (ARQ) feedback messages to reduce unnecessary transmissions by notifying the transmitter of the last acknowledged block in the ARQ feedback message. | 06-10-2010 |
20100153809 | METHODS AND SYSTEMS USING WINDOW START UPDATE FOR WIRELESS COMMUNICATION HARQ CONNECTION - Embodiments of the present disclosure allow a HARQ transmitter to provide a receiver an indication of the protocol data units (PDUs) that should not be expected because they are part of a data burst that has been retransmitted a maximum allowable number of times. The indication message may contain a maximum serial number contained in the data burst that has reached the maximum number of retransmissions, or the serial number of a first PDU in the next data burst. | 06-17-2010 |

20080276887 | EXHAUST GAS RECIRCULATION SYSTEM OF VEHICLE - An exhaust gas recirculation system. A water jacket in a cylinder block is configured for coolant to flow therein. A cylinder head is attached to the cylinder block. A cylinder is disposed in the cylinder block and the cylinder head. An intake manifold runner is connected to an intake hole of the cylinder. An exhaust manifold runner is connected to an exhaust hole of the cylinder. A first recirculation gas pathway is disposed in the cylinder block, and receives recirculated exhaust gas from the exhaust manifold runner. A second recirculation gas pathway is disposed in the cylinder head, and has a first end connected to the first recirculation gas pathway and a second end connected to the intake manifold runner. A recirculation valve, mounted at the second recirculation gas pathway, controls supply of the recirculated exhaust gas to the intake manifold runner. An engine control unit controls the recirculation valve. | 11-13-2008 |
20090241876 | VARIABLE VALVE LIFT APPARATUS - A variable valve lift apparatus includes an input cam disposed to a input shaft, a valve opening unit, a control shaft parallel to the input shaft, an input link rotatably coupled to the control shaft and contacting the input cam, a control link connected with the input link and eccentrically connected to the control shaft, a connecting link connected with the control link, and a lift arm that is rotatably coupled to the control shaft, is connected with the connecting link, and drives the valve opening unit. | 10-01-2009 |
20100139632 | Exhaust Gas Recirculation System with Unified Cylinder Head and Exhaust Gas Recirculation Device - An exhaust gas recirculation system of an internal combustion engine where a cylinder head having an intake port and an exhaust port is coupled to a cylinder block, and a portion of an exhaust gas exhausted from the exhaust port is flowed into the intake port through a control valve, may include a recirculation gas gallery integrally formed at the cylinder head and communicated with the intake port, a control valve assembly including the control valve and communicated with the recirculation gas gallery, and at least a recirculation gas extracting unit that is communicated with the control valve assembly and the exhaust port. | 06-10-2010 |

20090255496 | CONTINUOUS VARIABLE VALVE LIFT DEVICE - A continuous variable valve lift device includes a valve, which opens/closes a channel by means of reciprocation, a control shaft, which is mounted so as to be able to move toward or away from a reciprocation central axis of the valve, a pivotable shoe, which is pivotably coupled to the control shaft, includes a cam insertion part in a recess or through-hole shape and a slide face slidably contacting an end of the valve, and reciprocates the valve when pivoted, and a drive cam, which comes into contact with an inner wall of the cam insertion part, and pivots the pivotable shoe. Thereby, the continuous variable valve lift device can freely adjust a lift amount and a lift time of the valve without changing positions of the drive cam and camshaft, and thus be easily applied to an existing engine. | 10-15-2009 |
20140182275 | APPARATUS AND CATALYST CAN FOR EXHAUST GAS OF VEHICLE - A catalyst can of exhaust gas can include a catalyst embedded substantially in the center of an inner space of the catalyst can, and an inflow space and a discharge space partitioned in an upper part and a lower part of the catalyst can, respectively. The catalyst can also includes an inflow-side partition vertically cutting and dividing the inflow space into a plurality of partial inflow spaces, and an inlet formed for each partial inflow space. | 07-03-2014 |
20140182555 | ENGINE WITH DUAL INJECTOR - An engine includes two injectors that inject fuel in an intake port connected with one combustion chamber and allows overcoming the technical limits of the related art and achieving more appropriate fuel injection in accordance with the operation sections of an engine, thereby improving fuel efficiency and output of the engine with more efficient operation. | 07-03-2014 |
20140366838 | INTAKE SYSTEM FOR ENGINE - Output performance of the engine may be maximized by a configuration in which air is supplied so as to maximize volumetric efficiency of the respective cylinders in a multi-cylinder engine including a plurality of cylinders. | 12-18-2014 |
