`
`BACKGROUND OF THE INVENTION
`
`[000 1] This invention relates to audio player devices and more particularly to systems
`
`that include headphone listening devices. The new audio system uses an existing
`
`headphone jack (i.e., this is the standard analog headphone jack that connects to wired
`
`headphones) of a music audio player (i.e., portable CD player, portable cassette player,
`
`portable A.M./P.M. radio, laptop/desktop computer, portable MP3 player, and the like) to
`
`connect a battery powered transmitter for wireless transmission of a signal to a set of
`
`battery powered receiving headphones.
`
`[0002] Use of audio headphones with audio player devices such as portable CD players,
`
`portable cassette players, portable A.M./P.M. radios, laptop/desktop computers, portable
`
`MP3 players and the like have been in use for many years. These systems incorporate an
`
`audio source having an analog headphone jack to which headphones may be connected
`
`by wire.
`
`[0003] There are also known wireless headphones that may receive A.M. and F.M. radio
`
`transmissions. However, they do not allow use of a simple plug in (i.e., plug in to the
`
`existing analog audio headphone jack) battery powered transmitter for connection to any
`
`music audio player device jack, such as the above mentioned music audio player devices,
`
`for coded wireless transmission and reception by headphones of audio music for private
`
`listening without interference where multiple users occupying the same space are
`
`operating wireless transmission devices. Existing audio systems make use of electrical
`
`wire connections between the audio source and the headphones to accomplish private
`
`listening to multiple users.

`
`
`
`Continuation from Appl. No. 12/144,729
`Atty. Docket No. 1028.4
`
`[0004] There is a need for a battery powered simple connection system for existing music
`
`audio player devices (i.e., the previously mentioned music devices), to allow coded
`
`digital wireless transmission (using a battery powered transmitter) to a headphone
`
`receiver (using a battery powered receiver headphones) that accomplishes private
`
`listening to multiple users occupying the same space without the use of wires.
`
`SUMMARY OF THE INVENTION
`
`[0005] The present invention is generally directed to a wireless digital audio system for
`
`coded digital transmission of an audio signal from any audio player with an analog
`
`headphone jack to a receiver headphone located away from the audio player. Fuzzy logic
`
`technology may be utilized by the system to enhance bit detection. A battery-powered
`
`digital transmitter may include a headphone plug in communication with any suitable
`
`music audio source. For reception, a battery-powered headphone receiver may use
`
`embedded fuzzy logic to enhance user code bit detection. Fuzzy logic detection may be
`
`used to enhance user code bit detection during decoding of the transmitted audio signal.
`
`The wireless digital audio music system provides private listening without interference
`
`from other users or wireless devices and without the use of conventional cable
`
`connections.
`
`[0006] These and other features, aspects and advantages of the present invention will
`
`become better understood with reference to the following drawings, description and
`
`claims.

`
`DETAILED DESCRIPTION
`
`[0008] The following detailed description is the best currently contemplated modes for
`
`carrying out the invention. The description is not to be taken in a limiting sense, but is
`
`made merely for the purpose of illustrating the general principles of the invention.
`
`[0009] Referring to Figures 1 through 3, a wireless digital audio music system 10 may
`
`include a battery powered transmitter 20 connected to a portable music audio player or
`
`music audio source 80. The battery powered wireless digital audio music transmitter 20
`
`utilizes an analog to digital converter or ADC 32 and may be connected to the music
`
`audio source 80 analog headphone jack 82 using a headphone plug 22. The battery
`
`powered transmitter 20 may have a transmitting antenna 24 that may be omni-directional
`
`for transmitting a spread spectrum modulated signal to a receiving antenna 52 of a battery
`
`powered headphone receiver 50. The battery powered receiver 50 may have headphone
`
`speakers 75 in headphones 55 for listening to the spread spectrum demodulated and
`
`decoded communication signal. In the headphone receiver 50, fuzzy logic detection may
`
`be used to optimize reception of the received user code. The transmitter 20 may digitize
`
`the audio signal using ADC 32. The digitized signal may be processed downstream by an
`
`encoder 36. After digital conversion, the digital signal may be processed by a digital low
`
`pass filter. To reduce the effects of channel noise, the battery powered transmitter 20
`
`may use a channel encoder 38. A modulator 42 modulates the digital signal to be
`
`transmitted. For further noise immunity, a spread spectrum DPSK (differential phase
`
`shift key) transmitter or module 48, is utilized. The battery powered transmitter 20 may
`
`3
`
`SONY Exhibit - 1002 - 0008
`
`
`
`Continuation from Appl. No. 12/144,729
`Atty. Docket No. 1028.4
`
`contain a code generator 44 that may be used to create a unique user code. The unique
`
`user code generated is specifically associated with one wireless digital audio system user,
`
`and it is the only code recognized by the battery powered headphone receiver 50 operated
`
`by a particular user. The radio frequency (RF) spectrum utilized (as taken from the
`
`Industrial, Scientific and Medical (ISM) band) may be approximately 2.4 GHz. The
`
`power radiated by the transmitter adheres to the ISM standard.
`
`[0010] Particularly, the received spread spectrum signal may be communicated to a 2.4
`
`GHz direct conversion receiver or module 56. Referring to Figures 1 through 4, the
`
`spread spectrum modulated signal from transmit antenna 24 may be received by receiving
`
`antenna 52 and then processed by spread spectrum direct conversion receiver or module
`
`56 with a receiver code generator 60 that contains the same transmitted unique code, in
`
`the battery powered receiver 50 headphones. The transmitted signal from antenna 24
`
`may be received by receiving antenna 52 and communicated to a wideband bandpass
`
`filter (BPF). The battery powered receiver 50 may utilize embedded fuzzy logic 61 (as
`
`graphically depicted in Figures 1, 4) to optimize the bit detection of the received user
`
`code. The down converted output signal of direct conversion receiver or module 56 may
`
`be summed by receiver summing element 58 with a receiver code generator 60 signal.
`
`The receiver code generator 60 may contain the same unique wireless transmission of a
`
`signal code word that was transmitted by audio transmitter 20 specific to a particular
`
`user. Other code words from wireless digital audio systems 10 may appear as noise to
`
`audio receiver 50. This may also be true for other device transmitted wireless signals
`
`operating in the wireless digital audio spectrum of digital audio system 10. This code
`
`division multiple access (CDMA) may be used to provide each user independent audible
`
`enjoyment. The resulting summed digital signal from receiving summary element 58 and
`
`direct conversion receiver or module 56 may be processed by a 64-Ary demodulator 62 to
`
`demodulate the signal elements modulated in the audio transmitter 20. A block de(cid:173)
`
`interleaver 64 may then decode the bits of the digital signal encoded in the block
`
`interleaver 40. Following such, a Viterbi decoder 66 may be used to decode the bits
`
`encoded by the channel encoder 38 in audio transmitter 20. A source decoder 68 may
`
`further decode the coding applied by encoder 36.

`Continuation from Appl. No. 12/144,729
`Atty. Docket No. 1028.4
`
`[0011] Each receiver headphone 50 user may be able to listen (privately) to high fidelity
`
`audio music, using any of the audio devices listed previously, without the use of wires,
`
`and without interference from any other receiver headphone 50 user, even when operated
`
`within a shared space. The fuzzy logic detection technique 61 used in the receiver 50
`
`could provide greater user separation through optimizing code division in the headphone
`
`receiver.
`
`[0012] The battery powered transmitter 20 sends the audio music information to the
`
`battery powered receiver 50 in digital packet format. These packets may flow to create a
`
`digital bit stream rate less than or equal to 1.0 Mbps.
`
`[00 13] The user code bits in each packet may be received and detected by a fuzzy logic
`
`detection sub-system 61 (as an option) embedded in the headphone receiver 50 to
`
`optimize audio receiver performance. For each consecutive packet received, the fuzzy
`
`logic detection sub-system 61 may compute a conditional density with respect to the
`
`context and fuzziness of the user code vector, i.e., the received code bits in each packet.
`
`Fuzziness may describe the ambiguity of the high (1 )/low (0 or -1) event in the received
`
`user code within the packet. The fuzzy logic detection sub-system 61 may measure the
`
`degree to which a high/low bit occurs in the user code vector, which produces a low
`
`probability of bit error in the presence of noise. The fuzzy logic detection sub-system 61
`
`may use a set of if-then rules to map the user code bit inputs to validation outputs. These
`
`rules may be developed as if-then statements.
`
`[0014] Fuzzy logic detection sub-system 61 in battery-powered headphone receiver 50
`
`utilizes the if-then fuzzy set to map the received user code bits into two values: a low (0
`
`or -1) and a high (1 ). Thus, as the user code bits are received, the "if' rules map the
`
`signal bit energy to the fuzzy set low value to some degree and to the fuzzy set high value
`
`to some degree. Figure 4 graphically shows that x-value -1 equals the maximum low bit
`
`energy representation and x-value 1 equals the maximum high bit energy representation.
`
`Due to additive noise, the user code bit energy may have some membership to a low and
`
`high as represented in Figure 4. The if-part fuzzy set may determine if each bit in the
`
`user code, for every received packet, has a greater membership to a high bit
`
`representation or a low bit representation. The more a user code bit energy fits into the
`
`5
`
`SONY Exhibit - 1002 - 0010
`
`
`
`Continuation from Appl. No. 12/144,729
`Atty. Docket No. 1028.4
`
`high or low representation, the closer its subsethood, i.e., a measure of the membership
`
`degree to which a set may be a subset of another set, may be to one.
`
`[0015] The if-then rule parts that make up the fuzzy logic detection sub-system 61 must
`
`be followed by a defuzzifying operation. This operation reduces the aforementioned
`
`fuzzy set to a bit energy representation (i.e., -1 or 1) that is received by the transmitted
`
`packet. Fuzzy logic detection sub-system 61 may be used in battery-powered headphone
`
`receiver 50 to enhance overall system performance.
`
`[00 16] The next step may process the digital signal to return the signal to analog or base
`
`band format for use in powering speaker(s) 75. A digital-to-analog converter 70 (DAC)
`
`may be used to transform the digital signal to an analog audio signal. An analog low pass
`
`filter 72 may be used to filter the analog audio music signal to pass a signal in the
`
`approximate 20 Hz to 20 kHz frequency range and filter other frequencies. The analog
`
`audio music signal may then be processed by a power amplifier 74 that may be optimized
`
`for powering headphone speakers 75 to provide a high quality, low distortion audio music
`
`for audible enjoyment by a user wearing headphones 55. A person skilled in the art
`
`would appreciate that some of the embodiments described hereinabove are merely
`
`illustrative of the general principles of the present invention. Other modifications or
`
`variations may be employed that are within the scope of the invention. Thus, by way of
`
`example, but not of limitation, alternative configurations may be utilized in accordance
`
`with the teachings herein. Accordingly, the drawings and description are illustrative and
`
`not meant to be a limitation thereof.
`
`[0017] Moreover, all terms should be interpreted in the broadest possible manner
`
`consistent with the context. In particular, the terms "comprises" and "comprising" should
`
`be interpreted as referring to elements, components, or steps in a non-exclusive manner,
`
`indicating that the referenced elements, components, or steps may be present, or utilized,
`
`or combined with other elements, components, or steps that are not expressly referenced.
`
`Thus, it is intended that the invention cover all embodiments and variations thereof as
`
`long as such embodiments and variations come within the scope of the appended claims
`
`and their equivalents.

`
`ABSTRACT
`
`[0018] A wireless digital audio system includes a portable audio source with a digital
`
`audio transmitter operatively coupled thereto and an audio receiver operatively coupled
`
`to a headphone set. The audio receiver is configured for digital wireless communication
`
`with the audio transmitter. The digital audio receiver utilizes fuzzy logic to optimize
`
`digital signal processing. Each of the digital audio transmitter and receiver is configured
`
`for code division multiple access (CDMA) communication. The wireless digital audio
`
`system allows private audio enjoyment without interference from other users of
`
`independent wireless digital transmitters and receivers sharing the same space.
