Appeal No. 1997-2585
Application 07/930,880
1. A video system which provides an operator of a
vehicle with an enhanced visual display of selected portions
of the vehicle's surrounding environment comprising:
an illuminator to project short wavelength infrared
energy;
a single silicon detector for both short wavelength
infrared and visible colored light electromagnetic radiation
to generate both short wavelength infrared signals and visible
colored light signals;
a signal processing circuit to produce electrical
signals corresponding to the detected electromagnetic
radiation and based on said short wavelength infrared signals
and said visible colored light signals;
the signal processing circuit converting the
electrical signals corresponding to the detected short
wavelength infrared radiation into a visual display for the
vehicle operator; and
the signal processing circuit enhancing the visual
display of the infrared signal with selected portions of the
colored light signal.
The Examiner relies on the following references:
Harada et al. (Harada) 4,651,001 Mar. 17, 1987
Lillquist et al. (Lillquist) 4,679,068 July 7, 19871
1The Examiner’s final rejection was incorrectly based on
the U.S. Patent No. 4,751,571 to Lillquist issued June 14,
1988 and was corrected in the supplemental examiner’s answer
mailed August 19, 1996 by introducing new grounds of rejection
based on the U.S. Patent No. 4,679,068 to Lillquist et al..
