Abstract: There are disclosed systems, methods and processes for the distribution of information, typically digital information that is distributed actively, through broadcast media such as television and radio, displays, such as signage, etc., or passively, through displays such as signage or the like. The information can be captured from broadcasted transmissions, scanned from a display, or obtained by being transmitted to the user, who responded to a broadcast with a transmission to a receiving point during a period synchronized with the broadcast, requesting the information sent to his transmitted address. The captured or obtained information may include coupons or the like, that may be redeemed after being successfully captured or obtained.

Abstract: A detector for detecting touches by fingers or like body parts on a sensor comprises at least one sensing conductor, typically a grid of such conductors, extending into the sensor, a source of oscillating electrical energy at a predetermined frequency, and detection circuitry for detecting a capacitive influence on the sensing conductor when said oscillating electrical energy is applied, the capacitive influence being interpreted as a touch. The detector is advantageous in that the same sensing conductors can be used both for touch sensing and for detection of an electromagnetic stylus.

Abstract: Apparatus for user input to a digital system, comprising a first sensing system for sensing a user interaction of a first type, co-located with a second sensing system for sensing a user interaction of a second type. The first system may detect styluses and like objects using EM radiation and the second system may detect touch pressure.
