Abstract: A portable electronic device with a touch screen display displays an incoming message from a party to a user of the device while the device is locked. The device responds to detecting a user request to view the incoming message by immediately displaying a set of messages between the user and the party in a chronological order. While the device is unlocked, if an incoming message is longer than a predefined length the device displays a portion of the incoming message, a view icon, and a long-message indicia. Alternately, if the incoming message is equal to or less than the predefined length, the device displays the entire incoming message and a reply icon. In response to user selection of either the view icon or the reply icon, the device immediately displays a set of messages between the user of the device and the party in a chronological order.

Abstract: A regenerative selective logarithmic detector amplifier (LDA) can have integrated FM demodulation capabilities. It can receive a wired or wireless FM modulated signal and amplify or demodulate it with high sensitivity, high skirt ratio and minimized noise when compared to the prior art. When used in conjunction with other circuits such as a PLL or mixer, it can improve interference rejection and frequency selectivity and be locked on a precise channel in frequency and phase. The LDA produces intermittent oscillations that are self-quenched when reaching a given threshold. It also embeds the circuitry to perform direct FM discrimination. FM demodulation process is completed by a simple analog or digital frequency to voltage converter. This plus the fact that the instantaneous regeneration gain is low-medium permit to detect signals of small amplitudes buried in the noise.
