Abstract: A method for intraoral imaging obtains a digital image of one or more teeth and detects first and second boundaries. At each of the first and second boundaries, there is calculated a boundary ratio of mean gray-scale values for the tooth area on one side of the boundary to mean gray-scale values for background areas on the other side. The calculated boundary ratios are stored. A third ratio of the mean gray-scale values for the tooth area near the first boundary to the mean gray-scale values for the tooth area near the second boundary is calculated and stored. A vector is formed and stored that contains at least the calculated boundary ratios and the third ratio. The tooth surface is classified as either smooth or occlusal according to the stored vector. The image data is processed according to the classification and processing results are reported.

Abstract: A method for forming a color surface contour image of one or more teeth projects each of a plurality of structured patterns onto the one or more teeth and records image data from the structured pattern onto a monochrome sensor array. Surface contour image data is generated according to the recorded image data from the structured pattern projection. Light of first, second, and third spectral bands is projected onto the one or more teeth and first, second, and third color component image data is recorded on the monochrome sensor array. The first, second, and third color component image data is combined with color calibration data to generate a set of color values for each image pixel. The generated set of color values is assigned to the corresponding pixel in the generated surface contour image data to generate the color surface contour image. The generated color surface contour image is displayed.

Abstract: A novel method of selecting an electrical power, to be applied to a subject head-based flying height actuator during operation of a disk drive, is disclosed and claimed. A touch-down power for each of a plurality of representative heads is detected. A relationship between back-off power and touchdown power for the plurality of representative heads is estimated. A touch-down power for the subject head is detected. A back-off power for the subject head is calculated using the estimated relationship and the detected touch-down power for the subject head. The electrical power to be applied to the subject head-based flying height actuator is selected to be equal to the detected touch-down power for the subject head minus the calculated back-off power for the subject head.
