DEFINITION

Classification: 257/223

Having structure to improve output signal (e.g., antiblooming drain):

(under subclass 222) Subject matter wherein the non-external signal responsive device includes structural means, e.g., a drain element which reduces or eliminates optical blooming to improve the signal generated by the device in response to the non-electrical input signal.
