    摘要： The system of the present invention is configured to detect moisture on a surface and includes a sensor (32) that may be divided into a plurality of subwindows. At least one of the subwindows (110) has a sensitivity that is independently variable. The system may further include an optical system operative to direct light rays from at least a portion of the surface onto the sensor (32), and a processing system in communication with the sensor (32) and operative to independently adjust the sensitivity of the at least one subwindow (110) and to analyze data from the sensor to detect moisture. The processing system may control the windshield wipers based upon a number of subwindows (110) in which moisture is detected.

    摘要： A control system (1, 2) for controlling an image array sensor (3) and controlling communication between the image array sensor (3) and a microcontroller (5) by way of a serial communication interface (6). The control system (1, 2) is able to efficiently control various aspects of the image array sensor (3) such as windowing, mode of operation, sensitivity as well as other parameters in order to reduce the data throughput. An important aspect of the invention relates to the fact that the control circuit (1, 2) can be rather easily and efficiently configured in CMOS with relatively few output pins which enable the control circuit (1, 2) to be rather easily and efficiently integrated with CMOS based image array sensors (3) and even the microcontroller (5) to reduce the part count and thus, the overall cost of the system.

    摘要： Continuously variable headlamps offer greater flexibility for roadway illumination but offer challenges in automatic control design. Each continuously variable headlamp has an effective illumination range varied by changing at least one parameter from a set including horizontal direction aimed, vertical direction aimed, and intensity emitted. A system for automatically controlling continuously variable headlamps on a controlled vehicle includes an imaging system capable of determining lateral and elevational locations of headlamps from oncoming vehicles and tail lamps from leading vehicles. The system also includes a control unit that can acquire an image from in front of the controlled vehicle. The image covers a glare area including points at which drivers of oncoming and leading vehicles would perceive the headlamps to cause excessive glare. The image is processed to determine if at least one oncoming or leading is within the glare area. If at least one vehicle is within the glare area, the headlamp illumination range is reduced. Otherwise, the headlamp illumination range is set to full illumination range.

    摘要： A control system (20) for automatically detecting moisture on the windshield (26) of a vehicle. The automatic moisture detecting system (20) includes an optical system (30) for imaging a portion of the windshield (26) onto an image array sensor (32), such as a CMOS active pixel sensor. The voltages of each of the pixels which represents the illumination level is converted to a corresponding gray scale value by an analog digital converter (35). The gray scale values corresponding to the image are stored in memory (38). The spatial frequency composition of the gray scale values are analyzed to determine the amount of rain present. In order to provide a control signal to control the operation of the windshield wipers (40) of the vehicle as a function of the amount of moisture present. The system is also adapted to detect the level of fog both on the interior of the windshield (26) as well as the exterior of the windshield (26). By providing a system for automatically detecting the presence of fog on the interior and exterior of the windshield (26), serious performance limitations of known automatic rain sensors are eliminated.
