摘要： The present disclosure provides novel techniques to segment mobile entities based on signals from mobile devices associated with these mobile entities. In certain embodiments, a data file is built for each mobile entity to transform originally extremely high dimensional raw data derived from mobile devices communicating with a network into structured data characterizing associated mobile entities. The data files are structured for filtering and searching with respect to features associated with the signals from mobile devices, including location and non-location features. The data files are used to determine feature gains corresponding respectively to features related to a mobile segment. The features include first features of a first type and second features of a second type. The feature gains are used, among other things, to rank mobile entities for the mobile segment, with feature gains corresponding to the first features given a larger weight than feature gains corresponding to the second features.

摘要： A signal driving method is provided. One signal driving cycle includes two signal driving periods in which drive signals are applied to P detection electrodes. The method comprises, in a first period, applying non-inverting and inverting drive signals respectively to M adjacent detection electrodes and N adjacent detection electrodes. The non-inverting and inverting drive signals respectively applied to the M and N electrodes cancel each other out, M+N≤P and |M−N|≤Q. The method further comprises, in a second period, applying the non-inverting and inverting drive signals respectively to K adjacent detection electrodes and L adjacent detection electrodes. The non-inverting and inverting drive signals respectively applied to the K and L electrodes cancel each other out, K+L≤P, |K−L|≤Q and M+K≥P. Q denotes a number of detection electrodes which makes an active pen not cause moire after the cancelling, and P denotes a number of detection electrodes not greater than a number of detection electrodes on a touch control screen.
