Abstract: An antenna diversity receiving system is disclosed which includes an antenna device with a plurality of FM antennas and a controllable switching circuit for sequentially switching through one of the plurality of FM antennas via an antenna cable to a receiver upon reception of a switching control signal. The receiver has a multipath detector coupled to a pulse generator for generating a pulse signal to be used as such switching control signal. To secure accurate detection of the switching control signal, the pulse generator is coupled to a pulse shaper to convert the pulse signal of the pulse generator into a pulse signal pair. The pulse signal pair has a first signal pulse followed by a second signal pulse having a signal polarity opposite to the signal polarity of the first signal pulse. The pulse signal pair has a waveform varying symmetrically around a reference level and is supplied through the antenna cable to the antenna device.
Abstract: A method and apparatus for a user controlled voicemail management system (UCVMS) is provided. The UCVMS includes a first interface for interfacing with a voice mail provider, the first interface for receiving a voicemail message from the voice mail provider, the voice mail message including an owner identification. The UCVMS further includes a repository for storing the voicemail message, the repository being accessible only to the owner by using the owner identification.
