Title: Simulating short depth of field to maximize privacy in videotelephony
Inventor: GARRISON WILLIAM J
IPC: C08C19/44
Filed: 2008-03-27
Abstract: An arrangement for simulating a short depth of field in a captured videophone image is provided in which the background portion of the image is digitally segregated and blurred to render it indistinct. Thus, the displayed video of a user in the foreground is kept in focus while the background appears to be out of focus. Image tracking or fixed templates are used to segregate an area of interest that is kept in focus from the remaining captured video image. Image processing techniques are applied to groups of pixels in the remaining portion to blur that portion of the captured video image. Such techniques include the application of a filter that are alternatively selected from convolution filters in the spatial domain (e.g., mean, median, or Gaussian filters), or frequency filters in the frequency domain (e.g., lowpass or Gaussian filters).

Title: Improvements in or relating to photo electric cells
IPC: H01L31/0475
Filed: 1942-07-20
Abstract: 558,300. Light-sensitive cells. EVANS ELECTROSELENIUM, Ltd., VESZI, G. A., and MARKUS, P. July 20, 1942, No. 10081. [Class 40 (iii)] In manufacturing a unit battery of semiconductor photoelectric cells of the blocking or barrier layer type, the layers of the cells are built up in situ on a common insulating supporting base. As shown in Figs. 1 and 2, the base layers 2 of the several cells are made on a common insulating block 1, the semiconductor layers 3 are next applied and then the transparent layers 4. These overlap the edges of the base layers of adjacent cells so as to connect the several cells in series. Adjacent rows of such cells are connected by parts 4a as shown, or by external conductors crossing over from one side to the other. The connection between the adjacent cells may be made by overlapping the layers 4 over the adjacent layers 3, instead of over the adjacent layers 2. When this alternative is used, production of opposed voltages is prevented at the overlapping points in various ways, for example : (a) the overlapping parts of the layers 4 are made less transparent by increasing the thickness or by a non-transparent covering ; (b) a conducting material may be interposed between the overlapping portions ; (c) the portions of the layers 3 where the overlaps occur are ground or otherwise suitably treated ; (d) the top layer is constituted by two superimposed different metals, the top one only of which overlaps the layer 3 of the adjacent cell ; and (e) the undesired blocking layer is deteriorated by forced ageing.
