DETAILED DESCRIPTION OF THE INVENTION
The inventor provides a system and method for fielding phone calls from various types of audio-capable devices through one central and computerized piece of hardware. The system and methods of the invention are described below according to the following embodiments.
Referring to FIG. 1, in one embodiment connection device 101 comprises a USB port 106 connected to USB circuitry 108, a land-line telephone port 107 connected to land-line telephony interface circuitry 109, an analog audio headset 104 connected to an analog audio interface 110, a wireless interface 111, and internal circuitry 112. In the example shown in FIG. 1 the headset 104 is plugged into port 113 connected to analog audio interface 110. In some embodiments the headset may have circuitry within the headset to translate between analog audio protocol and USB protocol, and will in that situation connect to port 113 coupled to a second USB interface instead of the analog audio port indicated.
As shown in FIG. 1 the connection device may interact with a standard PC computer 102 or any other communication device having USB input and output, a standard land line telephone 103, or any wireless-capable mobile communication device 105, which in this example is a cellular telephone, but might be an iPad or other electronic pad device, or any other device capable of near-field pairing.
The connect device is in various embodiments operable with any device or program capable of sending and receiving audio, and having the correct inputs, including a laptop computer, any standard PSTN land line telephone, or any Bluetooth-capable mobile phone or tablet running on any number of operating systems.
A standard PC or laptop computer 102 may connect to device 101 through USB port 106 connected to USB interface 108. PSTN land-line telephone 103 may connect to land-line telephone interface 109. In most circumstances interface 109 may be a four-wire analog interface. Any wireless-pairing—capable cellular device connects wirelessly using a near-field technology to wireless interface 111, which includes Bluetooth pairing circuitry in this embodiment. USB interface 108, land-line telephone interface 109, wireless interface 111, and analog audio interface 110 all connect to internal circuitry 112, which is configured in various embodiments to protocols from these different audio sources into an audio signal that the user can hear through headset 104 and to which the user may respond through the microphone of the headset, also in analog audio mode.
In one embodiment of this invention, a user may have laptop computer 102, a land-line telephone 103, and a cellular device with Bluetooth capability all connected to device 101. Normally the user would have to answer calls from these different devices individually, but when these devices are connected to connection device 101, the user can interact with calls from any of these devices through headset 104.
Referring now to FIG. 2, the user interface of connection device 101 comprises USB ports 106, 113, and land-line port 107. The face of device 101 comprises buttons to enable connection between the user's headset and land-line telephone 104, Bluetooth device 105, and any softphone operating on a USB-capable device through USB port 106. There may also be a mute button 201, an Answer/End call button 202, which may be a toggle to use both to answer and to end a call, a volume increase button 204, a volume decrease button 205, and a Konfer button 203.
A user with the headphones 104 can field calls from different devices connected to various ports of Konnect device 101 as previously described by using one of three buttons 208 to connect to a land-line call, 207 to connect to a call from a BluetoothTM device, or other wirelessly-connected devices in other embodiments, or 206 to connect to a call from a USB-enabled device, such as, for example a call from a softphone executing on PC 102, like a Skype call or a Google Chat call.
Konfer button 203 allows a user to conduct a conference call with multiple callers who may be using any number of different devices through a series of switching functions and translation software within connection device 101, implemented in internal circuitry 112.
Referring now to FIG. 3, elements 307, 308, 309, 310, 311, and 312 all represent translation software necessary to translate between audio streams in different protocols. Switches SW-A 301, SW-B 302, SW-C 303, SW-D 304, SW-E 305, and SW-F 306 all represent switching circuitry for connecting audio streams between different ports through the various software translation functions.
In one embodiment of this invention a user is connected to connection device 101 using headset 104 connected through analog audio interface 110. Should the user need to field a call from a computerized softphone program like Skype through USB interface 108, only switch SW-A 301 would need to be closed, allowing the connection device 101 to connect the softphone application with the user on headset 104 through translation software 310, translating between USB audio class protocol and analog audio protocol in both directions.
In another embodiment of this invention a user might need to field a call from a landline telephone through landline interface 109. In this instance, only switch SW-C 303 would be closed, allowing the connection device 101 to connect the landline telephone with the user on headset 104 using software translation instance 312. Software 312 will translate between four-wire analog audio at the landline interface 110 to analog audio at headphone interface 109.
In another embodiment of this invention, a user might need to field a call from a Bluetooth-capable cellular device interacting with Bluetooth interface 111. In this instance, only switch SW-B 302 would be closed, allowing the connection device 101 to connect the cellular telephone call with the user on headset 104 using software instance 311, translating between Bluetooth audio and Analog audio.
In another embodiment of this invention, a user might need to conduct a conference call with other callers using different audio protocols. In this instance, the user would make use of Konfer button 107 in order to allow the different audio protocols to interact with one another, as well as with headset device 104. Depending on what types of audio protocols are being used by the various users, the appropriate switches would close, allowing the necessary software routines to be engaged.
The embodiments described above are examples. Many alterations in these embodiments can be made within the spirit and scope of the invention. The invention is limited only by the claims that follow.
