The mobile telephone industry has been associated with tremendous growth over the last several years. For instance, in the recent past, mobile telephones were only available to those of highest economic status due to service costs and costs associated with mobile phones. Moreover, network coverage was not extensive enough to enable robust service. In particular, only areas associated with dense population were provided with extensive wireless network coverage. Still further, the mobile phones that could utilize the networks to communicate were quite bulky, causing portation of the phone over any significant distance to be difficult at best. In more detail, antennas associated with these phones could be over a foot in length, thus making it difficult to utilize the phones in automobiles or other similar areas.
In contrast, today's portable phones (and other portable devices) can be utilized as full-service computing machines. For example, many of the most recent and advanced mobile phones can be associated with word processing software, accounting software, and various other types of software. Furthermore, network coverage has expanded to cover millions, if not billions, of users. Additionally, mobile phones have decreased in both size and cost. Specifically, modern mobile phones are often small enough to slip into an individual's pocket without discomforting the individual. Furthermore, many mobile network service providers offer phones at extremely low cost to customers who contract for service with such providers.
As portable phones are continuously associated with increased affordability, more and more individuals across various demographics are becoming users of portable phones. For instance, due to a desire to quickly and conveniently locate their children, many parents are providing such children with portable telephones. Similarly, an increasing number of individuals of advancing age are purchasing and using cellular telephones. As a consequence, an increasing number of people who use hearing aids to increase their quality of life are using cellular telephones or are desiring to use cellular telephones.
Conventionally, however, use of portable telephones by those who utilize hearing aids has been difficult due to detrimental effects of radio frequency (RF) interference on hearing aids, wherein the RF interference is associated with mobile telephones. In more detail, mobile telephones emit RF signals in order to facilitate communications in its serving network. The radiated RF signals have the potential to be demodulated by various non-linear devices (such as hearing aids) that are near the antenna of the mobile telephone. Hearing aid users may notice that some mobile telephones cause audible interference that can compromise intelligibility of speech received through the mobile telephone. The severity of the interference is influenced by a number of factors, such as the antenna design of the mobile telephone, transmitter output power, arlink type and device form factor. For instance, in a Global System for Mobile Communications (GSM) device, demodulated RF signal bursts can be audible as a low-frequency “buzz”, which, in some instances, can completely render speech incomprehensible.
One manner for reducing affects of RF interference with respect to hearing aids is to alter radiation characteristics of a mobile telephone, such that as little power as possible is provided to an earpiece of the phone. This can be accomplished through modifying the antenna, for example. Changes of this type, however, can cause a reduction of network coverage with respect to the mobile telephone, resulting in an increasing number of dropped calls. Additionally, changes made to an antenna can result in undesirable changes to a shape, size, and weight of a mobile telephone.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview, and it is not intended to identify key/critical elements of the claimed subject matter or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
The claimed subject matter is directed generally towards enhancing user satisfaction with mobile telephones, and particularly towards reducing unwanted noise perceived by users of hearing aids, wherein such noise is caused by radio frequency (RF) interference radiated from mobile telephones. As described above, today's hearing aids can detect and demodulate such RF interference, often resulting in a “buzzing” noise provided to a hearing aid user that is employing a mobile telephone to effectuate wireless communications. To reduce an amount of such noise perceived by a user, a mobile telephone can be configured to analyze transmitter operating parameters and generate an acoustic burst (that is out of phase with the RF interference) based at least in part upon such parameters. Thus, audible RF interference will be reduced.
It is understood, however, that different hearing aids can be associated with unique characteristics, such as microphone response delay, and other timing-related parameters. For instance, a digital hearing aid may have a demodulation delay in the order of milliseconds while an analog hearing aid may have a demodulation delay in the order of nanoseconds. Additionally, imperfections during manufacturing can cause two hearing aids of identical type to be associated with different timing parameters. Therefore, the inventors have contemplated training the mobile telephone such that unique parameters of hearing aids are accounted for, thereby enabling a generator within the mobile phone to synchronize an anti-phase acoustic burst with radio frequency interference at the hearing aid. For example, the mobile telephone can provide several default profiles, which can relate to hearing aid type, manufacturer, and/or the like. These profiles can be associated with approximate timing parameters with respect to a certain type of hearing aid. Thereafter, instructions can be provided to a user by way of a graphical user interface, wherein the instructions relate to informing the user of buttons to depress, for instance, to alter when an anti-phase acoustic burst is transmitted. Once the mobile phone has been trained, a profile specific to the user/hearing aid can be created and saved within the phone for later usage.
In another aspect, speech signals can be briefly cached prior to being transmitted to reduce occurrences of the anti-phase acoustic burst negatively impacting the speech signals. Due to an amount of pauses in conventional speech, the caching should be seamless to the user of the mobile phone. Such selective caching can be undertaken by monitoring transmission slots and caching speech signals based at least in part upon such monitoring.
To the accomplishment of the foregoing and related ends, certain illustrative aspects are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles disclosed herein can be employed and is intended to include all such aspects and their equivalents. Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.
The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that such matter can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the claimed subject matter.
As used in this application, the terms “component” and “system” are intended to refer to a computer-related entity, either hardware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to being, a process running on a processor, a processor, a hard disk drive, multiple storage drives (of optical and/or magnetic storage medium), an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a server and the server can be a component. One or more components can reside within a process and/or thread of execution, and a component can be localized on one computer and/or distributed between two or more computers.
Furthermore, the claimed subject matter may be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques to produce software, firmware, hardware, or any combination thereof to control a computing device, such as a mobile handset, to implement the disclosed subject matter. The term “article of manufacture” as used herein is intended to encompass a computer program accessible from any computer-readable device, carrier, or media. For example, computer readable media can include but is not limited to magnetic storage devices (e.g., hard disk, floppy disk, magnetic strips . . . ), optical disks (e.g., compact disk (CD), digital versatile disk (DVD) . . . ), smart cards, and flash memory devices (e.g., card, stick, key drive . . . ). Additionally it should be appreciated that a carrier wave can be employed to carry computer-readable electronic data such as those used in transmitting and receiving electronic mail or in accessing a network such as the Internet or a local area network (LAN). Of course, those skilled in the art will recognize many modifications may be made to this configuration without departing from the scope or spirit of the claimed subject matter.
Turning now to the drawings,
To reduce a perceived amount of RF interference provided to a hearing aid 106, a generator component 108 can generate an acoustic anti-phase burst that is provided in conjunction with a speech signal to the hearing aid 106, wherein the anti-phase burst reduces effects of RF interference at the hearing aid 106 and is based at least in part upon the monitored operating parameters. For example, the generator component 108 can determine a phase and amplitude associated with RF interference and can create an acoustic burst with an appropriate amplitude and phase that is opposite of the phase of the demodulated RF interference. Thus, RF interference demodulated at the hearing aid 106 can be greatly reduced.
The generator component 108 can also be configured to adapt to changing environmental and/or wireless network conditions. For instance, amounts of RF radiation can change as a frequency band associated with a call alters. Thus, if a frequency hop occurs, the generator component 108 can recognize such hop and a change in RF radiations that result from the frequency hop. In another example, a user's geographic location with respect to one or more transmitting powers can affect an amount of RF signal that is emitted from a mobile telephone. Accordingly, the generator component 108 can recognize alterations in RF radiations and can adjust a phase and/or amplitude of an anti-phase acoustic burst output therefrom. Moreover, it is possible that an anti-phase acoustic burst can have a negative impact on a speech signal—the generator component 108 can take into account speech signal quality when generating an anti-phase acoustic burst. For instance, the generator component 108 may output an anti-phase acoustic burst that does not entirely cancel RF radiations demodulated by the hearing aid 106 to ensure that quality of speech received at the hearing aid 106 is at or above a threshold quality.
Now referring to
To undertake such training, the training component 202 can access a data store 204 that can include one or more profiles 206. For example, the profiles 206 can be default profiles that can be associated with a particular hearing aid manufacturer, a type of hearing aid (e.g., analog versus digital), and the like. The default profiles can be associated with approximate time delays, thereby reducing an amount of time a user otherwise may have to spend on training the generator component 108. Upon a default profile being selected (either automatically or manually by a user), the training component 202 can be employed to output interactive graphical displays that enable the user to adjust timing settings associated with the generator component 108. For instance, the graphical displays can request that a user hold the phone as if they were using it to speak and listen for undesirable audible signals resultant from RF interference. The user can then depress one or more buttons, enter voice commands, and/or the like until the undesirable audible signals are sufficiently reduced (or substantially cancelled). In other words, the training component 202 can train the generator component 108 to substantially match anti-phase acoustic bursts output therefrom with unique properties of the user's hearing aid under the conditions (e.g., transmitted RF power, frequency, . . . ) in use by the wireless communications device 102 at the time the training process is invoked. This initial training information can be used by the generator component 108 to alter the amplitude and phase of the anti-phase acoustic bursts as the operating parameters of wireless communications device 102 change dynamically during use. A resultant profile that includes this information for a given hearing aid can then be retained within the data store 204 and accessed when such user is utilizing the wireless communications apparatus 102.
The following example is provided to better illustrate utilization of the training component 202. A user of the hearing aid 106 may be utilizing the wireless communications apparatus 102 for a first time. Prior to utilizing the wireless communications apparatus for purposes of voice communications, the user of the hearing aid 106 can access a menu and indicate to the wireless communications apparatus 102 that such user employs the hearing aid 106. The user can then be provided with instructions for selecting a default profile based at least in part upon a manufacturer of the hearing aid and/or a type of hearing aid. In another example, a single default profile can be existent within the data store 204 (thereby eliminating a need for the user to select a default profile). Moreover, rather than providing graphical displays to the user, audible commands or other suitable man-machine interfaces can be employed.
In still another example, a user may not be required to provide input relating to type of hearing aid, manufacturer of a hearing aid, and the like. Rather, a sensor component (not shown) can sense a type or manufacturer of hearing aid when such hearing aid becomes proximate to the wireless communications apparatus 102. Thus, for instance, the hearing aid 106 and the wireless communications apparatus 102 can communicate by way of Bluetooth, by way of a Near Field communications, or other suitable protocol. In yet another example, the wireless communications apparatus 102 may be associated with digital camera functionality, and it may be able to capture a photograph of the hearing aid 106 and analyze the photograph to determine a type and/or manufacturer of the hearing aid 106 or capture a barcode on the hearing aid 106 and perform a barcode scan operation. Still further, the hearing aid 106 may be equipped with an interface that enables the wireless communications apparatus to be wired to the hearing aid 106, and information relating to the hearing aid 106 can be provided by way of such wired connection. The wireless communications apparatus 102 can be updated with latest hearing aid profiles by accessing or being provided with updated libraries that include such profiles. Contents of the libraries can be downloaded to the phone over the air and/or through a side load to a computing device, such as a PC, a PDA, etc. A default profile can thereafter be automatically selected based upon determined type and/or manufacturer of the hearing aid 106.
Once a default profile has been selected, the user can be prompted to place the wireless communications apparatus 102 as if they were utilizing such apparatus 102 to effectuate wireless communications. The user can afterwards be prompted to perform adjustments that effectively reduce unwanted noise (caused by RF interference) perceived by the user of the haring aid 106. Once the user of the hearing aid 106 is satisfied, a profile for such hearing aid can be stored within the data repository 204 and can be accessed at any suitable time by the user. Thus, multiple users can use the wireless communications apparatus 102, wherein each user can select a particular profile to reduce perceived effects of RF interference. The monitor component 104 can analyze transmitter operating parameters of the apparatus 102, and these parameters can be employed by the generator component 108 (together with profile information) in connection with outputting an anti-phase acoustic burst that reduces perceived affects of the RF interference. The generator component 108 can output such burst according to timing parameters determined during training (as retained within a stored profile).
Therefore, in summary, the system 200 can utilize profile data in conjunction with knowledge of transmitter operating parameters of the wireless communications apparatus 102 to reduce undesirable noise perceived by users of hearing aids. For example, when a user invokes a training sequence to reduce interference to the hearing aid 106, the wireless communications apparatus 106 can monitor and track transmitter output power, frequency, etc. that are in use at the time. Such information can be utilized to create an algorithm that can be employed by the wireless communications apparatus 106 to dynamically produce anti-phase bursts as the transmitter characteristics alter. These changes often occur (rapidly) in a field environment.
With reference now to
The wireless communications apparatus 102 can additionally include a profile selector component 304 that can select a profile from within the data store 204 based at least in part upon data sensed by the sensor component 302. For example, two users may share use of the wireless communications apparatus 102, such that different profiles should be associated with the different users. A user can enter identification information, such as a personal identification number, into the wireless communications apparatus 102, and the entry can be sensed by the sensor component 302. The sensor component 302 can inform the profile selector component 304 that a particular profile within the data store 204 should be utilized when generating anti-phase acoustic bursts (based upon the user ID).
In another example, the sensor component 302 can sense an orientation of the wireless communications apparatus 102 with respect to a user. For instance, a user may use different hearing aids in different ears, and thus different profiles may exist for disparate ears with respect to different users. The sensor component 302 can detect when the wireless communication apparatus 102 rotates about an axis in a certain amount of time, thus indicating that the user has translated the wireless communications apparatus 102 from a left ear to a right ear, for example. Such sensed transition can be provided to the profile selector component 304, which can thereafter select a profile that accords to the sensed information. Still further, information such as temperature, humidity, and the like can cause a profile to change or a parameter of a profile to change. The sensor component 302 can be configured to sense such information and the profile selector component 304 can select a profile based upon the sensed data. In still another example, as described above, the wireless communications apparatus can automatically determine identity of the hearing aid through, for instance, a wired connection therebetween, a wireless connection therebetween, use of photograph analysis, etc.
The wireless communications apparatus 102 can also include a graphical user interface component 306 that can output or display sensed parameters, available profiles, and the like. Thus, the graphical user interface component 306 can be employed to provide a user with text, graphics, and/or speech that aids the user in selecting a profile and/or displaying to the user a selected profile. In an example, a user of the hearing aid 106 can have previously selected a profile from within the data store 204, such that audible interference associated with RF signals radiated from the wireless communications apparatus 102 is reduced through the generator component 108 emitting anti-phase acoustic burst(s). The user may then transition the phone from an ear associated with the hearing aid 106 to her other ear. The sensor component 302 can detect that the orientation of the wireless communications apparatus 102 has altered, and such sensed alteration can be provided to the profile selector component 304. The profile selector component 304 can automatically select a profile from the data store 204 that is associated with the second ear, and the generator component 108 can utilize such profile in connection with reducing audible RF interference. Additionally, the graphical user interface component 306 can generate a graphical indication to the user that a profile has been automatically altered.
Turning now to
To enable this synchronization, the wireless communications apparatus 102 can include the training component 202, which in turn can be associated with an interface generator component 402. The interface generator component 402 can display one or more instructions to a user of the wireless communications apparatus 102 with respect to synchronizing the generator component 108 (through use of a profile). For example, the interface generator component 402 can provide instructions for depressing certain keys to alter timing in particular directions. Screens can be provided in a specific sequence to enable efficient synchronization of the generator component 108. A user input receiver component 404 can receive user input that is provided in response to instructions displayed through use of the interface generator component 402. For instance, a series of screens displaying the question “is noise reduced or enhanced?” can be provided as the generator component 108 is synchronized through use of the training component 202, and the user input receiver component 404 can facilitate receipt of such input. Thereafter, screens generated by the interface generator component 402 can be based at least in part upon input received from the user input receiver component.
In another example, the interface generator component 402 can output screens that enable multidimensional input to be utilized to train the wireless communications apparatus. For instance, voice recognition (e.g., a statement indicating that a sample is associated with echo and needs reduced volume), two dimensional graphical user interfaces, a set of slider bars, and the like can be utilized to acquire parameters in multiple dimensions concurrently.
Now referring to
The anti-phase acoustic burst can be provided to a transmitter component 502 that is utilized to transmit signals from the wireless communications apparatus 102 to the hearing aid 106. In an example, the transmitter component 502 can transmit the anti-phase acoustic burst (together with voice signals) to an earpiece associated with the wireless communications apparatus 102 (in the case of acoustic coupling between a mobile telephone and the hearing aid 106) or to a mobile telephone's “T-coil” (in the case of magnetic induction coupling of audio from a mobile telephone to a T-coil equipped hearing aid). In some instances, however, the anti-phase acoustic burst generated by the transmitter component 502 can interfere with speech signals that are desirably provided to a user of the hearing aid 106. To reduce occurrences of such interference, a timing component 504 can be employed to monitor (continuously) a time slot used for transmission such that the anti-phase acoustic burst will be properly synchronized, especially since the time slot may alter during a call. Because the wireless communications apparatus 102 has knowledge of time slot(s) in use, the timing component 504 can be employed to adjust timing of the anti-phase acoustic burst accordingly. Moreover, the timing component 504 can be used with respect to reducing interference of the anti-phase acoustic burst with the speech signal through offsetting (in time) the anti-phase cancellation burst relative to the wireless communication device's receive speech audio. In other words, the receive audio (received speech signals) can be delayed according to timing parameters of the timing component to allow blanking of a transmitted anti-acoustic burst. Under such conditions, it may be desirable for the wireless communications apparatus to generate some sort of “comfort” noise to mask the effects of the anti-phase bursts.
To aid in delaying speech audio, a caching component 506 can be employed that caches audio signals desirably provided to the user of the hearing aid 106, wherein the caching component 506 caches the signals according to timing parameters determined by the timing component 504. Thus, in other words, the timing component 504 and the caching component 506 can act in conjunction to adaptively cache speech audio to allow anti-phase acoustic bursts to be generated by the generator component 108 to reduce “buzzing” heard by a user of the hearing aid 106. The caching can occur over a segment of time that is sufficient enough in length to generate anti-phase acoustic bursts. The delays can be compensated for during pauses in speech over the course of a call.
The mobile telephone 600 can also include a microphone 604 that receives audio signals and conveys the signals to at least one on-board processor for audio signal processing, and an audio speaker (proximate to an earpiece) 606 for outputting audio signals to a user, including processed voice signals of a caller and recipient music, alarms, and notification tones or beeps. Moreover, the audio speaker 606 can be associated with outputting anti-phase acoustic bursts to a user of a hearing aid. Additionally, the mobile telephone 600 can include a power source such as a rechargeable battery (e.g., Alkaline, NiCAD, NiMH and Li-ion), which can provide power to substantially all onboard systems when the user is mobile.
The mobile telephone 600 can further include a plurality of multi-function buttons including a keypad 608, menu navigating buttons 610 and on-screen touch sensitive locations (not shown) to allow a user to provide information for dialing numbers, selecting options, navigating the Internet, enabling/disabling power, training the mobile telephone 600 to output anti-phase acoustic bursts while accounting for unique hearing aid properties, and navigating a software menu system including features in accordance with telephone configurations.
A display 612 can be provided for displaying information to the user such as training screens, a dialed telephone number, caller telephone number (e.g., caller ID), notification information, web pages, electronic mail, and files such as documents, spreadsheets and videos. The display 612 can be a color or monochrome display (e.g., liquid crystal, CRT, LCD, LED and/or flat panel), and can be employed concurrently with audio information such as beeps, notifications and voice. Where the mobile telephone 600 is suitable for Internet communications, web page and electronic mail (e-mail) information can also be presented separately or in combination with the audio signals.
In an example, the display 612 can be utilized in connection with a graphical user interface (GUI) 614. The GUI 614 can include a viewing window 616 where data (e.g., instructions) can be displayed to the user. The user can navigate through the data via a slider 618 and a scroll bar 620. For instance, instructions can be provided in connection with training the mobile telephone 600, and a user can use the slider 618 and/or the scroll bar 620 in connection with reading the instructions and providing feedback in accordance with the instructions. The menu navigating buttons 610 can further enable the user to interact with the display information. In support of such capabilities, the keypad 608 can provide keys that facilitate alphanumeric input, and are multifunctional such that the user can respond by inputting alphanumeric and special characters via the keypad 608. The keypad keys also allow the user to control at least other telephone features such as audio volume and display brightness.
An interface can be utilized for uploading and downloading information to memory, for example, the reacquisition time data to the telephone table memory, and other information of the telephone second memory (e.g., website information and content, caller history information, address book and telephone numbers, and music residing in the second memory). A power button 622 allows the user power on and off the mobile telephone 600. The mobile telephone 600 can further include memory for storing information. The memory can include non-volatile memory and volatile memory, and can be permanent and/or removable. The mobile telephone 600 can further include a high-speed data interface 624 such as USB (Universal Serial Bus) and IEEE 1394 for communicating data with a computer. Such interfaces can be used for uploading and downloading information, for example website information and content, caller history information, address book and telephone numbers, and music residing in the second memory. In addition, the mobile telephone 600 can communicate with various input/output (I/O) devices such as a keyboard, a keypad, and a mouse.

If the user is satisfied, then at 914 a new profile is created that reflects the user input, and such profile can be stored to memory for use when the user is utilizing the mobile telephone.

A monitor 1144 or other type of display device is also connected to the system bus 1108 via an interface, such as a video adapter 1146. In addition to the monitor 1144, a computer typically includes other peripheral output devices (not shown), such as speakers, printers, etc.
The computer 1102 may operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 1148. The remote computer(s) 1148 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer 1102, although, for purposes of brevity, only a memory/storage device 1150 is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1152 and/or larger networks, e.g., a wide area network (WAN) 1154. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which may connect to a global communications network, e.g., the Internet.
When used in a LAN networking environment, the computer 1102 is connected to the local network 1152 through a wired and/or wireless communication network interface or adapter 1156. The adaptor 1156 may facilitate wired or wireless communication to the LAN 1152, which may also include a wireless access point disposed thereon for communicating with the wireless adaptor 1156.
When used in a WAN networking environment, the computer 1102 can include a modem 1158, or is connected to a communications server on the WAN 1154, or has other means for establishing communications over the WAN 1154, such as by way of the Internet. The modem 1158, which can be internal or external and a wired or wireless device, is connected to the system bus 1108 via the serial port interface 1142. In a networked environment, program modules depicted relative to the computer 1102, or portions thereof, can be stored in the remote memory/storage device 1150. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers can be used.
The computer 1102 is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, restroom), and telephone. This includes at least WiFi and Bluetooth™ wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.
WiFi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. WiFi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. WiFi networks use radio technologies called IEEE 802.11 (a, b, g, etc.) to provide secure, reliable, fast wireless connectivity. A WiFi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). WiFi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11a) or 54 Mbps (802.11b) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices.
What has been described above includes examples of the claimed subject matter. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but one of ordinary skill in the art may recognize that many further combinations and permutations of such matter are possible. Accordingly, the claimed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
This application is a continuation of U.S. patent application Ser. No. 11/459,041, filed on Jul. 21, 2006, entitled RADIO FREQUENCY INTERFERENCE REDUCTION IN CONNECTION WITH MOBILE PHONES, the entirety of which is incorporated herein by reference.
