Abstract: A method of detecting a defect in a sheet of glass includes: (i) directing a converging beam from a source of illumination onto a surface of the sheet of glass to illuminate the defect; (ii) focussing an image capture device onto a first plane to image the defect in the sheet of glass; (iii) capturing a first image of the defect; (iv) carrying out an adjustment step; and (v) capturing a second image of the defect. Each of the first and second images has a respective first portion from the illuminated defect and a respective second portion due to reflection of a portion of the beam from the glass surface. In the first image of the defect the first portion is brighter than the second portion, and in the second image of the defect the first portion is darker than the second portion. An apparatus for carrying out the method is also provided.

Abstract: A method of aligning a plurality of color channels of a projector is provided. The method includes: for each color channel, (i) projecting test pattern on a surface; (ii) capturing image of the test pattern generated on the surface; and (iii) adding the captured image to an image set. Once the captured images for each color channel are added to an image set, identifying a reference position based on the image set. This is followed by processing the image set to estimate a divergence of the respective test patterns for each color channel with respect to the reference position, followed by computing a corrective function for each color channel and applying the respective corrective function to each color channel to align the color channel to the reference position.

Abstract: A vehicle comprises a driver display on which is displayed an advisory maximum wading speed according to the current wading depth of the vehicle. The advisory speed is in one embodiment displayed on the vehicle speedometer. The display may also include an elevation of a vehicle on which is indicated one or more of maximum wading depth, current wading depth and vehicle inclination.

Abstract: A vehicle (100) comprising a wading information display (1020) and a wading depth sensor, the display showing an elevation of a vehicle on which is superimposed the current wading depth. The display may also indicate simultaneously the maximum wading depth calculated according to the ride height of the vehicle, the inclination of the vehicle by inclination of the displayed elevation, and an advisory speed according to wading depth and/or vehicle inclination.

Abstract: A vehicle (100) comprising a wading information display (1020), a memory and a processor, the memory containing a program configured to run on the processor to calculate the maximum wading depth of the vehicle from the measured suspension travel, and to display the maximum wading depth on the display. The display may also show a dual wading depth, an advisory wading speed, and vehicle inclination.
