摘要： The rising edge of a pulse width modulated output signal occurs after an input ramp signal starts to rise. The ramp signal starts to rise after the rising edge of a periodic set signal and before the falling edge of a periodic set signal. A feedback control signal intersects a substantially linear region of the ramp signal to generate a reset signal using a PWM comparator. The periodic set signal and reset signal are input to a latching circuit to generate the pulse width modulated output signal. The minimum pulse width can approach zero while having adequate overdrive to the PWM comparator. Having the rising edge of the reset signal rise before the falling edge of the set signal can allow a zero percent duty cycle without the need for a ramp offset voltage.
摘要翻译：在输入斜坡信号开始上升之后发生脉宽调制输出信号的上升沿。斜波信号在周期性设置信号的上升沿之后和周期性设置信号的下降沿之前开始上升。反馈控制信号与斜坡信号的基本线性区域相交，以使用PWM比较器产生复位信号。周期性设置信号和复位信号输入到锁存电路以产生脉宽调制输出信号。当PWM比较器具有足够的过驱动时，最小脉冲宽度可以接近零。在复位信号的上升沿在设置信号的下降沿之前上升可以允许零百分比的占空比而不需要斜坡失调电压。

摘要： A method, apparatus, and computer program product are presented for estimating a camera reference horizon Ŷ0. Operations include receiving images including projections of objects including horizontal edges. Vertical motion is estimated for the images and is stored. The projection of horizontal edges in the images is computed. The projected edges are segmented out and motion is compensated. Projections of the horizontal edges from image to image are used to generate tracks. Active track storage is maintained by adding data to update the storage from each subsequent image. The tracks are screened using a criteria set to produce a subset of tracks to enhance track reliability. Distances to, and heights of, the objects are then estimated. Further screening is performed by calculating an error criteria for each track and selecting a subset satisfying the error criteria. The remaining tracks are used to generate a camera reference horizon estimate Ŷ0.

摘要： A method of mending and testing a semiconductor apparatus. Only one L-shaped laser target or one set of targets forming a T-shaped target is in use. By choosing a primary laser target on the device with a damaged circuit, and a reference laser target on a device peripheral to the device with the damaged circuit, the laser mending machine is fed with the data of the coordinates of the primary and reference targets. The positions of these targets are scanned and calculated by the laser mending machine. With the feeding of the relative coordinates of these targets into the laser mending machine, the position to be mended, that is, the position with a damaged circuit, is obtained correctly. The fuse in the damaged circuit is then blown, and the circuit replaced by a new circuit with the same function.
