Abstract: Systems and methods are described for downloading audio signals into a digital telephone to update and replace a conventional ringer tone. The source of the audio signal can be from any analog audio sound source, such as a radio, PC sound card, MP3 player, CD or DVD player, etc. The audio signal can be fed through an audio cable into a handset headset jack that is already available in most digital telephones, or into a specialized audio jack incorporated into the base (of a cordless telephone). The audio signal may be comprised of a song or speech. The audio signal can be stored in a specialized memory for storing audio signals without requiring encoding the signal prior to storage, or it can be stored in any conventional memory arrangement. For a cordless telephone, the audio signal may be stored in the handset or in the base unit.

Abstract: A system and method for facilitating transmission of voice and data between a PC and a remote telephony device. A cordless telephone system having a base station and at least one cordless handset also includes a first modem, caller ID functionality, and telephone answering machine functionality. A computer, having a second modem and a sound card is connected to the public switched telephone network (PSTN) via an adapter that has a controllable switch. After a connection is established between the first and second modems with the switch in a first configuration, the adapter is controlled to put the switch in a second configuration such that incoming signals transmitted from the base station over the PSTN are routed to the sound card. Accordingly, both data and audible signals can be retrieved by the computer from the base station over the same PSTN connection.

Abstract: Text messages are communicated between a personal computer and a cordless device having a base unit and a handset. Text messages sent from the personal computer to the handset are displayed on a text screen on the handset. Text message sent from the handset to the personal computer are displayed on a text window on the personal computer. Messages can be passed from the personal computer to a base unit of the cordless device using an analog or a digital interface. In addition, stereo music is transmitted from a stereo source to the handset through the base unit.

Abstract: Systems and methods for wireless communications between a cellular telephone and a landline telephone. A system includes a cellular telephone in communication with a cordless telephone base station. The cordless telephone base station includes a BLUETOOTH radio transceiver, and the cellular telephone includes a BLUETOOTH radio transceiver, so that the cellular telephone can communicate with the base station using BLUETOOTH communications. The cordless telephone base station includes a cordless radio transceiver, and a cordless handset that includes a cordless radio transceivers. The cordless handset can communicate with the cordless telephone base station using cordless radio frequency communications. The BLUETOOTH radio transceiver and the cordless radio transceiver of the cordless telephone base station are coupled so that the cordless handsets can communicate with the cellular telephone.

Abstract: A detachable shoulder rest apparatus for use with a telephone handset is provided, which includes a body portion and at least one attachment member to removably attach the body portion to the exterior of the telephone handset. The body portion may comprise a contoured wedge which conforms to the shape of the user's shoulder, and may be either substantially rigid or deformable. The at least one attachment member may take the form of a plurality of arms extending from the body portion which engage one or more slots or recesses on the handset, a hook member which engages with one or more slots or apertures on the handset, or a slot or aperture which engages with one or more projections or protrusions on the telephone handset. In another embodiment, the detachable shoulder rest apparatus includes a base portion joining the body portion and the attachment members, which may be separable from the body portion.

Abstract: An audio signal expander apparatus for integration into a satellite receiver for recovering audio signal transmissions carried by satellite services utilizing compressed audio signal transmission processing wherein the incoming audio signal is expanded by a ratio which varies with both the audio signal amplitude and audio signal frequency. The audio signal passes first through a low-pass filter and then through a frequency selective negative feedback circuit the output of which is filtered and de-emphasized. In addition, the level of the output audio signal may be varied by a level control adjustment.

Abstract: A wireless audio and video signal transmitter and receiver system apparatus capable of accepting both external baseband audio and video signal inputs and a modulated external audio/video signal modulated at a particular television channel. A transmitter transmits an audio/video signal to one or more remote receivers which regenerate the original audio/video signal providing both baseband audio and video signal outputs as well as a modulated audio/video signal output at the particular television channel. The transmitter includes a modulated audio/video signal input section and baseband audio and video signal input sections which provide audio sub-carrier and video baseband signals to a video/RF switch which permits the user to select between modulated and baseband inputs to the transmitter. The audio/video signal is AM modulated and up converted before being transmitted to the receiver.
