摘要:
Adaptive control can use hierarchical motion estimation (HME) and/or multiple reference motion estimation (MRME) for the motion estimation of current encoding blocks. Both HME and MRME are allowed in the motion estimation to achieve a high coding gain. Control consists of slice level control and macro-block (MB) level control. A slice is one or more contiguous macroblocks. In slice level control, it is decided to use only one reference frame or use multiple reference frames to coding current slice based on the motion vectors obtained in coarse level motion estimation. In MB level control, it is decided to perform MRME or perform HME for the MB and its subblocks based on the coarse level motion vectors of the MB.

A method of reducing bow and/or improving the electrical performance of an aluminum back contacted silicon solar cell includes applying to a silicon wafer substrate a paste including aluminum and an organometallic compound, and firing the substrate. The organometallic compound is a C1 to C30 organometallic compound of a metal selected from the group consisting of Ag, Al, Ba, Bi, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Nd, Ni, Sb, Si, Sn, Sr, Ta, V, Zn, Zr. A paste is formed having an exothermic reaction peak at a temperature of at least 300° C. to less than 660° C.

Solar cell contacts having good electrical performance are made by a process involving: (a) providing a silicon wafer substrate; (b) providing a paste comprising: (i) aluminum, (ii) glass frit, and (iii) a separate and distinct amount of at least one oxide, such that, together with the aluminum, the glass frit and oxide forms a paste having an exothermic reaction peak, at a temperature of at least 660° C. to less than 900° C., (c) applying the paste to the silicon wafer substrate to form a coated substrate, and (d) firing the coated substrate for a time and at a temperature sufficient to sinter the aluminum and fuse the glass frit and oxide.
摘要:
Methods and systems are provided for reducing audible clunks and objectionable drive feel in vehicles including start/stop systems. In one example, a vehicle engine is shutdown during vehicle coasting. The vehicle engine is then restarted, while the vehicle is moving with a torque converter clutch disengaged. A transmission clutch pressure is then adjusted during the restart based on a torque converter output speed relative to a torque converter input speed.
摘要:
An illumination device (1) comprises: at least one low-power light source (50); a power input stage (20) suitable for receiving AC low voltage from an electronic transformer (ET); a power buffer stage (30) having an input (31) connected to the input stage output (29); a driver (40) for driving the light source and receiving electric power supply from the power buffer stage. The power input stage generates output current pulses for charging the power buffer stage at a relatively low frequency, and during each output current pulse, the power input stage draws input current, the input current always having a current magnitude higher than a minimum load requirement of the electronic transformer.

A method for improving starting of an engine that may be repeatedly stopped and started is presented. In one embodiment, the method adjusts a transmission tie-up force in response to engine starting. The method may improve vehicle launch for stop/start vehicles.
摘要:
A method for controlling an upshift in a vehicle transmission includes transferring engine torque from an offgoing clutch to an oncoming clutch, using a torque capacity of the offgoing clutch to dampen oscillations when a difference between a speed of a transmission offgoing input and a calculated expected speed of said input is greater than a reference speed difference, and modulating engine torque during a ratio change phase of the shift.
