Abstract: A mobile communication device is equipped with hardware and/or software components to enable the device to output a data in a form of a radio frequency signal, emulating outputting of the data by either an active or a passive RFID transponder. The data may be a security key or an identifier. Emulation of an active RFID transponder includes facilitating selection of the data and instruction to output by a user. Emulation of a passive RFID transponder includes detecting for proximal presence of a RFID reader. Either case, provision of the data to the mobile communication device may include provision of associated signal attribute(s).

Abstract: Methods, apparatuses, and articles for receiving one or more input factors associated with scrolling behavior of a user are described herein. Based on the received one or more input factors, at least one of (1) a tunable scrolling algorithm and (2) one or more non-linear scrolling algorithms of a plurality of non-linear scrolling algorithms may be selected for use in evaluating the scrolling behavior of the user.
