  • Patent number: 8867592
    Abstract: In some embodiments, a receiver circuit is configured to receive a modulated signal from a transmitter that is galvanically isolated from the receiver circuit. The receiver circuit is configured to demodulate the modulated signal by using two comparator circuits that respectively detect the presence or absence of first and second signal states of a carrier signal. Based on the detection of the first and second states, the receiver circuit determines whether the carrier signal is present or absent in the modulated signal to determine a demodulated value of the modulated signal.

    Abstract: A user interface is implemented on a client device remote from a host device. The host device operates an application program that implements a user interface, such as an electronic programming guide or a guide for a personal video recorder, that permits a user to control at least one target device. The host device transfers to the client device an identification of at least one scene. In general, a scene defines an abstract layout for at least one screen display of the user interface. The client device generates at least one screen display for the scene based on its interpretation of the scene. The client device then displays the screen as an implementation of the user interface. Thereafter, a user initiates, using the client device, an operation to control the target device. In response, the target device performs the operation.
