  • Patent number: 10048815
    Abstract: The embodiments described herein provide improved sensor devices and methods that facilitate improved sensor devices. Specifically, the devices and methods provide capacitive image sensors that require only two layers of conductive elements formed on a single substrate. The ability to provide an image sensor using only a single substrate with two layers of conductive elements may substantially reduce the cost and complexity of the capacitive image sensor. In one embodiment, an input device is provided that comprises a first substrate having a first and second side. Each of the second array of second sensor electrodes comprises a plurality of isolated components disposed on the first side and a plurality of connectors disposed on the second side. The connectors and isolated components of the second sensor electrodes are arranged such that adjacent pairs of connectors along the first direction are separated by a distance substantially greater than the first pitch.

  • Publication number: 20070273765
    Abstract: At least one image of the environment is taken using either an image capturing device of the monitoring system. Based on the image of the environment, at least one background image is generated. The background image, which comprises a plurality of pixels, is divided into pixel blocks. In each pixel block, at least one data cluster is formed using at least one feature of the pixels in the pixel block. The data cluster formed in each pixel block is described as a data distribution having a mean value and a standard deviation from the mean value. After generating the background image, a subsequent image is taken by the monitoring system. Each pixel of the subsequent image is compared with the data cluster of the block of the background image correspond to the pixel, and a first discrepancy value is generated accordingly.
