Microsoft Patents The Body Bus 508

Mz6 writes "Microsoft has been awarded a patent for using human skin as a power conduit and data bus. Patent No. 6,754,472, which was published Tuesday, describes a method for transmitting power and data to devices worn on the body and for communication of data between those devices. In its filing, Microsoft cites the proliferation of wearable electronic devices, such as wristwatches, pagers, PDAs (worn on people's belts) and small displays that can now be mounted on headgear. "As a result of carrying multiple portable electronic devices, there is often a significant amount of redundancy in terms of input/output devices included in the portable devices used by a single person," says the filing. "For example, a watch, pager, PDA and radio may all include a speaker." To reduce the redundancy of input/output devices, Microsoft's patent proposes a personal area network that allows a single data input or output device to be used by multiple portable devices." (What about DoCoMo's research in this area?)

      SOLE MATES. At MIT's Media Lab, where corporate sponsors fund prototypes of new digital technologies, computers are appearing in wildly unlikely places. As part of a project called Things That Think, researchers have embedded a computer in a Nike Inc. sneaker. Using a piezoelectric polymer to generate power from foot movement, a computer in the heel might act as a sort of personal secretary. When two people shake hands, for instance, the skin-to-skin contact would be detected by sensors in each person's shoe. That would trigger an exchange of information--the computers could perhaps swap electronic business cards and check calendars for a future meeting date. Modified eyeglasses and wristwatches might display the data.

      Microsoft filed their patent (which is titled a "Method and apparatus for transmitting power and data using the human body") on April 27, 2000.

      Yet at this web site,, there is a white paper (dated November 18-19, 1996) where IBM demonstrates their "new Personal Area Network technology that uses the natural electrical conductivity of the human body to transmit electronic data".

      So, IBM demonstrated similar techniques back in 1996 that used the natural electrical conductivity to transmit data.

      However, Microsoft's claims focus on power, and frequency adjustments, this is basis for their ability to send data.

      One of Microsoft's claims states "modulating an information signal transmitted" using this signal; yet, in the IBM white paper it states that "The natural salinity of the human body makes it an excellent conductor of electrical current. PAN technology takes advantage of this conductivity by creating an external electric field that passes an incredibly tiny current through the body, over which data is carried."

      My gut says that many of MS's claims are voided by prior art -- but one would need to study the MS claims in detail, and compare it to DoCoMo's and IBM's research on the subject, to make a truly educated rebuttal.
      • And if you actually look at the Microsoft patent, you will see that they reference the IBM work as well as the DoCoMo patent. I suspect that if they thought these patents invalidated their application they would have realized it by now. At the very least, the patent examiner would have looked at the refereced patent and determinined they are suficiently different.

    A personal area network (PAN) is a technology that could enable wearable computer devices to communicate with other nearby computers and exchange digital information using the electrical conductivity of the human body as a data network. For example, two people each wearing business card-size transmitters and receivers conceivably could exchange information by shaking hands. The transference of data through intra-body contact, such as handshakes, is known as linkup. The human body's natural salinity makes it a good conductor of electricity. An electric field passes tiny currents, known as Pico amps, through the body when the two people shake hands. The handshake completes an electric circuit and each person's data, such as e-mail addresses and phone numbers, are transferred to the other person's laptop computer or a similar device. A person's clothing also could act as a mechanism for transferring this data.

    The concept of a PAN first was developed by Thomas Zimmerman and other researchers at M.I.T.'s Media Lab and later supported by IBM's Almaden research lab.

    sorry but MIT and IBM is way ahead of Microsoft in this with prior art.

    hell I made a example prototype from the information I recieved from mister Zimmerman back in 1997 for playing around with PAN's when i was heavy into the wearable computing research.

Everyone's hair rises, and whoever breaks the circuit gets the shock - but there was a circuit and power was being delivered, it was even doing work.

    Here's the problem:

    Patents are being awarded for spending a little time thinking. For having the luxury of free time to think, and company lawyers to file, companies are able to establish themselves as a gatekeeper.

    Patents should be the product of effort - they were meant to reward that effort, and incent you to expend that amount of effort again in the future.

    IMHO, these 'few hours of thought' patents are diametrically opposed to the concept of patents as enumerated in the Constitution.

    Isn't there SCADS of prior art on this topic How the hell does M$ think they are going to repatent Blue Tooth by simply stating all the devides are attached to a human body?

    Of course, if M$ is really smart, they will patent applying mild electric shock to the human skin and GRAFTING these devices to the skin (using the skin as a comm-conduit of course) THEN they might actually have something....oh wait, prior art again....see The Borg legal departmemnt.

    "We are Borg Legal, you will be litigated, resistance is futile, pleabargain is your only option" Come to think of it, isn't that how M$'s legal team works today?

    IMAO becouse IANAL some of this may not apply.

    The diffrence between MITs prior art and Microsofts patent is the power distrabution.
    But.. DU.. the data is electrical... power distrabution is an implied part of that.

    Any time you have a reliable electrical signal you have a power source.

    Basicly Microsofts patent is a minnor and obveous modification of an existing patent and as I understand it patenting the obveous is not permitted.

    Well I've thought of this for years, and also I've had some ideas including inserting small heat-devices near veins (inside body) to make the blood transport heat through the body.

    AND I've talked to others that have somewhat thought of similar ideas. I think this patent is just another nail in the coffin for the U.S. Patents.

    Excuse me for being arrogant, but you Americans should really start looking into what's happening.
