  • Patent number: 7945285
    Abstract: In one embodiment, a method of integrating a digital encoded-audio bit stream player in a radio-frequency (RF) telephone handset is disclosed. An RF connection is established between the RF telephone handset and an RF unit connected to a network, wherein communications between the RF telephone handset and the network pass through the RF unit. The RF telephone handset is switched from performing as a telephony device to performing as a digital encoded-audio bit stream player. Digital encoded-audio bit stream music is played from the RF telephone handset. The digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player is muted when the RF telephone handset receives a telephone call. The RF telephone handset is switched from performing as a digital encoded-audio bit stream player to performing as a telephony device while the telephone call is active.

  • Patent number: 7290036
    Abstract: The present invention relates to a new feature for e-mail services which provides a telephone call alert to a particular e-mail user when their e-mail server, web page e-mail server, or other e-mail receiving server receives new e-mail addressed to them. One or more designated telephone number (or numbers) are automatically called by an auto dialer at the e-mail server in response to the receipt of particularly identified high priority e-mail senders (e.g., from clients, from family, etc.). The particular designated telephone number(s) to call for a particular user are configured in a priority alert profile for that particular user, as are the possibility to limit the activation of the telephone call alert system to electronic messages received only from a select list of senders, and/or after a predetermined number of electronic messages have been received, and/or if a current time corresponds to a predetermined time to alert a recipient.

  • Patent number: 5940542
    Abstract: A method and apparatus is disclosed for encoding and decoding an input signal representative of video or audio information. A form of the method includes the following steps: processing the input signal to produce a sequence of vectors representative of the input signal; implementing a lattice vector quantization procedure on individual vectors of the sequence to identify a lattice point of a lattice that is closest to the individual vector and to obtain an index value representative of a labelling of the identified lattice point, the lattice vector quantization procedure including a multi-level allocation of groups of reserved indices, and selection of the index value for the individual vector within a group of reserved indices. The index signals representative of the index values are stored and/or transmitted, and then recovered for decoding. The decoding is operative to obtain a recovered sequence of vectors, and the sequence of vectors can be processed to produce an output signal.

The index signals representative of the index values are stored and then recovered for decoding, or transmitted before decoding. The decoding is operative to obtain a recovered sequence of vectors, and the sequence of vectors can be processed to produce an output signal.
