18th ISfTeH/IGS-111-1

Minimum Hardware Smart Simple and Wearable System for Patient Conducted Trans-Network Remote Fetal Monitoring, Proposed Architecture with Evaluation

s of Subsystem and Component

Yasuhito Takeuchi, Ph.D.

Akibagaoka Signaling Laboratory

37 Mikumicho, Hamamatsu 4328017 Japany.takeuchi@ieee.org

すみません：ネタ本あり。 1993 年のこれです。

（次ページ）

その後 20 年間の進歩ないし進捗 or 退歩を説明します。

フロントエンド回路技術、探触子の素材＆音響技術、ともにほとんど進歩も退歩もしていません。

利用技術に関して、大きな変革・発展がありました。

Styles of Fetal Monitoring

Doppler + Labor

Telemetric Transducer System

1978 - 1979

Doppler + Labor

Telemetric Transducer System

Reproduced in 2010

Doppler-Only

Telemeter Transducer

1980 - 1981

This Fantastic Doppler-Telemeter Prototype was

STOLENDuring On-Patient Long-Run Test, sometime 1980+

(Suspected Thief is Gravida Herself)

Personal Hearing Use Fetal Doppler Unit

etwa. 1993+-

FHR Monitoring by the

Doppler - Labor Telemeter

November 1979

etwa. 2 to 3 AM, Gravida=Sleeping, Fetus=Resting but Awake Phase

etwa. 5 to 6 PM, Gravida Actively Working in Kitchen,

Fetus Feeling Agitated and in Non-Resting Phase.

In 30 yearsThe Fetus in Prior Slides is now Fathering Another Fetus, and--

October 1979 (Play Back of Old Cassette Tape)

October 2010(Real Time Recording)

NO Essential PROGRESS in Doppler-Telemeter, for

>30 YEARS

Why?????

“Plug-in-Power”Vo=1.5V, Is=200μA

Per channel (2)

Fetal Phono Microphone for Plug-Power Jack

結論に代える“おすすめ”：

Mac や PC が、また携帯電話やその辺の録音機がアナログ屋に支給してくれる“餌”：

Macintosh: 開放電圧 3.9V 、短絡電流 12mA の独立 dc 電源

Power-In-Plug システム一般：開放電圧 1.5V 、短絡電流 200μA の信号線重畳 dc 電源 (L, R 2 チャンネル各々に )

結論に代える“おすすめ” ( つづき )

Mac や PC が、またその辺の今様の機器がアナログ屋に提供してくれるデータ取り込み仕様：

Macintosh, Power-In-Plug システムともに大方（具体的には各機種の仕様に依存するが）；

2ch., 16bit, 44.1KHz or 22.05KHz or 11.025KHz S/R,

5Hz Low Cut, Max. ＋ー 1v (2Vpp)

自己の内部雑音は 1~2 LSB 程度、非常によろしい。

　 DC オフセットあり、前処理フィルタしてから信号処理。

So/Then, How about Mobile Phones, i-Somethings, Tablets ----- PDAs.

Mostly Simple/Easy/Always-Available Interface with Operating Power Available

Can We Convert This to Fetal Phono??

Unforthnately the Answer is NO.

(Fetal) Phono is 100%-OUT of Limited Voice Band of Telephony

Can We Convert This to Fetal Doppler??

the Answer is “YES+but”

Needs Another Battery

Whatever Must Make Own is ------- Signal Transduction Device ONLY!!

Conclusion/Recommendation

Do/Make as NOTHING as Possible

Conclusion of Conclusion

Minimum Necessary Hardware (in patient side)

Doppler Transceiver ONLY

Rest of Necessary Resources are

ALL TRANS-NETWORK supported.

If One Like Phono or AECG rather than Doppler

Do Make Phono or AECG as You Like

HOWEVER

In using trans-internet voice channel for Doppler signal transmission

Transmission Latency Time is a BIG Issue

Time Domain Uncertainity >>Millisecond

ABSOLUTELY UNACCEPTABLE

For Beat-To-Beat Heart Rate Measurement

=NEEDS Another Solution

Source Time Marking for Reception Rearrangement,

or any possible method(s)

NOW

Reproducing the STOLEN Doppler telemeter

After 30 years laps time

With SOME novel components but majority are almost same as they were,

CONCLUSION

Do as NOTHING as Possible !!!!!!!!

EVERYTHING necessary is beyond the NETWORK or in CLOUD

Will this DESTROY business rather than MAKE business??

Will this DESTROY business rather than MAKE business?

Will this make a “business-destroying-business” rather than “business making business” ??------

You Should Address That Issue Of YourselfBy YourselfFor Yourself

Thanks for Attention
