## Title
Method and system for a wireless ear bud

## Abstract

Exemplary embodiments include methods and systems for detecting an incoming telephone signal, processing the incoming telephone signal, transmitting the processed signal to a remote receiver and alerting a remote user of the incoming signal.

## Background
BACKGROUND INFORMATION
Generally telephones operate through transmission of an electric signal over a telephone network which enables a telephone user to communicate with another telephone user. However, a telephone may alert a user of an incoming call by a loud ring tone which may be disruptive and non-discrete. A user may adjust the volume of a ring tone on a telephone, however, the ring tone may be adjusted to a low volume which may cause a user to miss an important telephone call. Also, the ring tone may be adjusted to a high volume which may disturb or interrupt a user or anyone near the user. The loud ring tone is a particular problem if a user wants to be alerted of a call without disturbing others, e.g., a sleeping baby.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
An exemplary embodiment provides a system and process for discretely alerting a user of an incoming telephone call by blocking a ring tone of a telephone. For example, a detection system may be connected to, integrated or otherwise associated with a telephone system, e.g., a telephone. The detection system may communicate with a remote system through a network, such as a wireless network. The remote system may be proximal to a remote user so that the remote user may be discretely notified of an incoming call without disturbing others nearby. Advantageously, the detection system may alert users of an incoming telephone call while allowing users to roam freely within a transmission coverage area of the wireless detection system. Additionally, the wireless detection system may enable a user to answer a telephone call while away from a telephone.
An exemplary wireless detection system may notify users of an incoming telephone call without disturbing others within a range of a telephone ring.

At block 402, the incoming signal may be processed. For example, signal may be filtered, amplified, modulated, etc. Other processing steps may be applied.

Also, the intermediate modulated signal may be filtered to remove any noise that may be incurred during signal processing to achieve a predetermined clarity.
The intermediate modulated signal may be processed to a radio frequency signal to be transmitted. In an exemplary embodiment, an oscillator may generate a signal associated with the intermediate modulated signal and/or radio frequency signal. The frequency of the signal generated by the oscillator may be determined based on the transmission radio frequency and/or the intermediate modulated frequency.

6. A device, comprising:
a receiver for receiving an incoming signal from a communication device attached to a telephone system, wherein the incoming signal is generated by a detector based at least in part on an inductively detected signal transmitted on a telephone line of the telephone system;
a processing unit for identifying information associated with the incoming signal;
an alerting unit for transmitting an alerting signal to a user for a first time period based at least in a part on the information associated with the incoming signal, wherein the alerting signal comprises one or more of a ring, a tone, music, a previously-recorded voice signal, and a vibration notification signal; and
a transmitter for transmitting user information to the communication device, wherein the user information is inducted by the detector as a signal onto the telephone line of the telephone system, wherein the detector enables audio communication between a user of the communication device and a user of the device,
wherein the detector is associated with at least one filter for suppressing the incoming signal at the telephone system for a second time period, wherein the first time period overlaps with the second time period, wherein suppressing the incoming signal comprises suppressing a notification associated with the incoming signal at the telephone system for the second time period while permitting the telephone system to answer a call associated with the incoming signal.

7. The device of claim 6, wherein the device is connected to one of a half-duplex communication system or a full-duplex communication system.

8. The device of claim 6, wherein the alerting unit comprises one or more of an ear piece, a head phone, a canalphone, a circumaural phone and a supra-aural phone.

9. The device of claim 6, wherein the processing unit further generates an intermediate frequency signal associated with the incoming signal and a predetermined signal associated with the incoming signal.

10. The device of claim 6, wherein the communication device comprises one or more of a wired telephone system, a mobile phone system, a satellite phone system and an IP telephone system.

11. A method, comprising:
detecting an incoming signal, wherein detecting the incoming signal comprises inductively detecting the incoming signal transmitted on a telephone line of a telephone system, wherein the incoming signal is detected by a detector;
processing the incoming signal by attenuating any noise associated with the incoming signal;
transmitting the processed incoming signal to a remote receiver associated with a remote user and transmitting the processed signal to a filter associated with the detector,
suppressing, via the filter associated with the detector, the incoming signal at the telephone system for a first time period, wherein suppressing the incoming signal comprises attenuating the incoming signal to suppress a notification associated with the incoming signal at the telephone system for the first time period while permitting the telephone system to answer a call associated with the incoming signal; and
receiving user information from the remote receiver associated with the remote user, wherein the user information is inducted by the detector as a signal onto the telephone line of the telephone system, wherein the detector enables audio communication between a user of a device that initiates the incoming signal and the remote user, wherein the first time period overlaps with a second time period that corresponds to receiving user information from the remote receiver.

12. The method of claim 11, wherein processing the incoming signal further comprises one or more amplifying, filtering, and modulating the incoming signal.

13. A non-transitory computer readable media comprising code to perform the acts of the method of claim 11.

14. A method, comprising:
receiving an incoming signal from a communication device, wherein the incoming signal is generated based at least in part on an inductively detected signal transmitted on a telephone line of a telephone system, wherein the incoming signal is generated by a detector;
processing the incoming signal and identifying information associated with the incoming signal;
transmitting an alerting signal to a remote user for a first time period based at least in a part on the information associated with the incoming signal, wherein the alerting signal comprises one or more of a ring, a tone, music, a previously-recorded voice signal, and a vibration notification signal; and
receiving user information from a remote receiver associated with the remote user, wherein the user information is inducted as a signal onto the telephone line of the telephone system, wherein the detector enables audio communication between a user of the communication device and the remote user, wherein the detector is associated with at least one filter for suppressing the incoming signal at the telephone system for a second time period, wherein the first time period overlaps with the second time period, wherein suppressing the incoming signal comprises suppressing a notification associated with the incoming signal at the telephone system for the second time period while permitting the telephone system to answer a call associated with the incoming signal.

15. The method of claim 14, wherein the processing the incoming signal comprises generating an intermediate frequency signal associated with the incoming signal and a predetermined signal associated with the incoming signal.

16. A non-transitory computer readable media comprising code to perform the acts of the method of claim 14.
