Abstract: An enhanced whisper feature enables a user to engage simultaneously in disparate telephonic communication sessions by isolating audible input of the user from a select one of the telephonic communication sessions while providing audible output from each of the telephonic communication sessions to the user. The whisper feature can be further enhanced using a presence system that maintains presence information indicating the availability of the user. The presence system can enable the whisper feature of the user upon determining that the user is currently engaged in a first telephonic communication session when a request for the user to engage in a second telephonic communication session is received. In addition, the whisper feature can include a silent ring mode that is activated upon receipt of the request for the user to engage in the second telephonic communication session.

Abstract: High precision continuous time gmC BPF (Band Pass Filter) tuning. A novel approach is presented by which a continuous time signal serves as a BPF control voltage for tuning of a BPF within a communication device (e.g., transceiver or receiver). A PLL (Phase Locked Loop) tunes the center frequency of the BPF using this continuous time signal, and the PLL oscillates at the center frequency of the BPF. The BPF is implemented as a gmC (transconductance-capacitance) filter, and the PLL is implemented using a number of gm (transconductance) cells as well. The PLL's gm cells and the BPF's gm cells are substantially identical in form. All of these gm cells are operated within their respective linear regions. This similarity of gm cells within the PLL and the BPF provide for substantial immunity to environmental perturbations including temperature and humidity changes as well as fluctuations of power supply voltages.

Abstract: Variable modulation with LDPC (Low Density Parity Check) coding provides for generation of LDPC coded symbols having different respective code rates and/or modulations. In addition, appropriate LDPC encoding, that generates an LDPC variable code rate signal, may also be performed as well. The encoding can generate an LDPC variable code rate and/or modulation signal whose code rate and/or modulation may vary as frequently as on a symbol by symbol basis. Some embodiments employ a common constellation shape for all of the symbols of the signal sequence, yet individual symbols may be mapped according different mappings of the commonly shaped constellation; such an embodiment may be viewed as generating a LDPC variable mapped signal. In general, any one or more of the code rate, constellation shape, and/or mapping of the individual symbols of a signal sequence may vary as frequently as on a symbol by symbol basis.

Abstract: Timing recovery optimization using disk clock. A novel means is presented to perform and provide control of the sampling frequency of a signal that is read from a disk within a hard disk drive (HDD). Two separate, yet somewhat cooperating control loops are employed to provide feedback control of the sampling frequency of the signal that is read from disk. A timing recovery loop and a disk clock loop operate in conjunction with one another according to some desired manner (which can be predetermined or adaptive) to ensure that the sampling of the signal is performed to a very accurate degree. In one implementation, the timing recovery loop governs the sampling rate until the disk clock loop has locked, from which time either the disk clock loop govern the sampling or some combination of the signals provided from the two loops govern the sampling.

Abstract: A gating logic receives a non-return-to-zero (NRZ) input signal and couples the NRZ input signal as an NRZ output signal when operating in a NRZ mode of operation and converts the NRZ input signal to a return-to-zero (RZ) output signal when operating in a RZ mode of operation. A circuit coupled to the gating logic receives a clock signal and couples the clock signal to the gating logic to convert the NRZ input signal to the RZ output signal in the RZ mode of operation. In the NRZ mode of operation, the circuit decouples the clock signal and places a predetermined signal state at the gating logic to pass through the NRZ input signal as the NRZ output signal. The circuit receives a select signal to select between the NRZ and RZ modes of operation and the NRZ and RZ modes are obtained by controlling the clock signal to the gating logic.
