Abstract: Disclosed are techniques for improving the color uniformity of a display of a display device. A plurality of images of the display are captured using an image capture device. The plurality of images are captured in a color space, with each image corresponding to one of a plurality of color channels. A global white balance is performed to the plurality of images to obtain a plurality of normalized images. A local white balance is performed to the plurality of normalized images to obtain a plurality of correction matrices. Performing the local white balance includes defining a set of weighting factors based on a figure of merit and computing a plurality of weighted images based on the plurality of normalized images and the set of weighting factors. The plurality of correction matrices are computed based on the plurality of weighted images.

Abstract: A surface cleaning apparatus having a dirt collection container which is removable from a remainder of the apparatus. The dirt collection container is held in a stored position relative the remainder of the apparatus by a holding device. The holding device includes a first co-operating member provided in, provided on or connected to the dirt collection container, a second co-operating member provided in, provided on or connected to the remainder of the apparatus. Movement of the dirt collection container towards its stored position engages the first and second co-operating members with each other and effects either rotation of the first co-operating member relative to the dirt collection container and/or rotation of the second co-operating member relative to the remainder of the apparatus.

Abstract: An apparatus to monitor for hypoglycaemia in a human, the apparatus including: two or more sensors to concurrently measure two or more physical properties over time, the physical properties including one or more temperatures and/or one or more movements of an arm and/or a hand of the human; and an electronic system configured to: receive signals representative of the measured physical properties; and process the received signals to generate an output indicative of hypoglycaemia in the human.
