摘要： Method and apparatus for detecting the presence of an analyte (e.g., gas/radiation) that utilizes color change detection mechanisms. The apparatus has an indicator that changes color in the presence of the analyte. For example, in the absence of the analyte, the indicator reflects a first color. In the presence of the analyte, the indicator reflects a second color. The apparatus includes a color sensor that receives light reflected from the indicator and based thereon generates one or more signals that represent the reflected light. The apparatus also includes a color change detection mechanism that is coupled to the color sensor and that receives the signal generated by the color sensor and based on the signal determines whether the indicator has changed to the second color. Once it is determined that the indicator has changed to the second color, an alarm can be generated or remedial measures can be initiated.

摘要： Method and apparatus for duplicating a target color and changing a color of an object to match the target color. A first color sensor measures the target color. A color projection mechanism selectively changes the color of the object. A color matching mechanism is coupled to the first color sensor for receiving the target color. Based on the target color, the color matching mechanism controls the color projection mechanism to change the color of the object to match the target color.

摘要： Scanner with light source calibration mechanism. The scanner includes a light source that generates a white light utilized to scan an image. The light source calibration mechanism includes a calibration color sensor that generates a calibration color sensor output. The light source calibration mechanism receives a predetermined color profile that can be, for example, the amount of red, green light, and blue light expected from the light source utilized by the scanner for scanning. The color calibration mechanism calibrates the light source of the scanner based on the output of the calibration color sensor and the predetermined color profile.

摘要： Method and apparatus for compensating for variations in the output signal of a color sensor due to varying temperature of the color sensor. The color sensor receives light and generates an output signal that is based on the received light. The temperature compensation mechanism measures the temperature of the color sensor and uses the measured temperature to selectively adjust the output signal of the color sensor to generate a compensated output signal that is not dependent on temperature of the color sensor.
