    摘要: A detector for providing position detection of objects over a sensor with a first and second set of conductor lines forming a grid with a plurality of junctions there between at which the conductor lines do not contact, includes a signal generator providing a signal to at least one conductor line of the first set of conductor lines, and circuitry detecting output arising from one or both of an electromagnetic stylus and one or more fingers when present. The output arising from each of the one or more fingers is detected from at least one conductor line of the second set of conductor lines in response to the signal provided to the at least one conductor line of the first set of conductor lines. The circuitry detects positions of one or both the electromagnetic stylus and each of the one or more fingers when present responsive to the output detected.

    摘要: 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.

    摘要: 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. Redemption may be either on-line, where a transmission of coupon information is transmitted to a call center, that places a product order with a supplier and handles payment details, or off-line, where the user takes to coupon to the retailer, for redemption at the point of sale.
