摘要： In a CCD image sensor, a CCD line memory is disposed between each vertical charge transfer device and a horizontal charge transfer device to selectively transfer charges from each vertical charge transfer device to the horizontal charge transfer device. A discharge drain is disposed along the horizontal charge transfer device to selectively discharge charges from vertical charge transfer devices via the horizontal charge transfer device to the discharge drain. Therefore, image data in which the numbers respectively of the vertical and horizontal pixels are reduced can be generated.

摘要： A multiple-wound, three-phase, variable speed motor having N independent winding sets is driven by N inverters, each responding to 1/N of the torque and excitation current commands, and the torque current is limited as a function of N times the limiting current each inverter may tolerate, when all inverters are functioning. When M inverters fail, they are disconnected from the motor, the torque current is limited as function of N-M times the limiting current each inverter may tolerate. The remaining N-M inverters may each respond to 1/(N-M) of the torque and excitation commands. The excitation current may be maximized as (N-M) times the limiting current divided by the square root of two. The speed command may be predetermined by the integration over an acceleration interval, of the maximum acceleration achievable with torque available from those of the inverters which have not failed, in view of the inverters' current limits.
