What is claimed is:
1. A wearable computer system, comprising:a plurality of devices that are electrically networked together via ahuman body to form the wearable computer system, the human body serving as atransmission medium for the plurality of devices,wherein a first of the plurality of devices automatically regulates thepower of a data signal transmitted from the first device to a second of theplurality of devices based on a power measurement of a signal received from thesecond of the plurality of devices, andwherein at least one of the plurality of devices transmits informationregarding the at least one device's location on the human body and is suppliedwith an amount of power in accordance with the transmitted location information.
2. The wearable computer system of claim 1, wherein the at least one of theplurality of devices is further configured to transmit an audio signal throughthe human body.

13. The wearable computer system of claim 1, wherein at least one of the pluralityof devices includes a kinetic power supply that converts kinetic energy generated
by the human body into electrical energy, the electrical energy being transmitted
via the human body to at least one of the plurality of devices to supply power tothe device.
＊＊＊END＊＊＊《参考》In FIG. 1, the system 10 comprises a plurality of portable devices 20, 22, 24, 26,
28, 30, and 32, which are coupled together by the human body 11. The portabledevices include a portable computer device 20, a pager device 22, a keyboard 24,
a display 26, an audio input device 28, an audio playback device 30 and a power
supply 32. Each of the devices is coupled to the human body by a pair ofelectrodes. Power and/or information may be transmitted between the portabledevices 20, 22, 24, 26, 28, 30, and 32 by using the body 11 as a conductive medium.
Body 11 serves as a bus to couple portable devices 20, 22, 24, 26, and 30 together.
Portable devices can transmit and receive power and transmit and receive
information, e.g., communications signals. In FIG. 2, the first through Nthportable devices, e.g., devices 20, 24, 26, each include a communications/power
module 21, 21', 21'' and device circuitry 23, 23', 23''. Communications/power
module 21 is responsible for interfacing with other devices in the network 10,
communicating with them, and receiving/sending power over the bus 11. Device
circuitry 23, 23', 23'' is circuitry which implements the specific functions theportable devices 20, 24, 26 are designed to support.

〔問２〕次の米国特許明細書中の背景技術にかかわる記載内容について翻訳しなさい。
＊＊＊START＊＊＊
Medical ultrasound devices commonly utilize a processing unit, a head thatis passed over a region to be imaged, and a cable that connects the head to theprocessing unit. The head, in turn, typically includes a row of piezoelectrictransducing elements that send ultrasonic vibrations into the region to be imaged,
and receive ultrasonic vibrations back from the region after the vibrations havebounced off of internal structures within the region.
The clarity of an ultrasonic image is proportional to the number ofpiezoelectric transducing elements that are used in a row of transducing elements.
As a result, the industry is moving to increase the number of piezoelectrictransducing elements that are used in a row, along with increasing the number ofrows of piezoelectric transducing elements that are used in a head.
One of the difficulties of increasing the number of piezoelectrictransducing elements is that each piezoelectric transducing element has acorresponding signal processing path. Conventionally, the signal processing path
includes a low noise amplifier (LNA), a variable gain amplifier (VGA), and ananalog-to-digital (A/D) converter.
Thus, if an ultrasonic device includes 256 piezoelectric transducing
elements in one or more rows, then the ultrasonic device also includes 256 LNAs,
256 VGAs, and 256 A/D converters that form 256 individual signal processing paths.
256 A/D converters, however, is a large number of A/D converters.
＊＊＊END＊＊＊〔問３〕次の米国特許明細書中の実施例にかかわる記載内容について翻訳しなさい。
＊＊＊START＊＊＊
The energy converter 110 includes active electrical circuitry such as adirect current to direct current (DC to DC) converter which converts energy fromthe batteries 106 to a form suitable for powering the device electrical circuitry
112. Where the device 100 is configured to accept both primary (non-rechargeable)
and secondary (rechargeable) batteries, or otherwise having different chemistries,
the converter 110 advantageously has an input dynamic range which accommodates
thevoltages produced by the relevant battery types. An alkaline battery, for example,4

has a nominal open circuit voltage of about 1.5 volts direct current (VDC), whereas
a nickel metal hydride (NiMH) battery has a nominal open circuit voltage of about
1.2 VDC. In an implementation in which the battery receiving region 104 isconfigured to receive two batteries connected electrically in series, the nominal
open circuit input voltage would thus range between about 2.4 for a device
containing two NiMH batteries and 3.0 VDC for a device containing two alkaline
batteries. Depending on the requirements of a particular application, it is also
desirable that the input dynamic range accommodate decreases in input voltage which
occur as the battery(ies) 106 are loaded and/or become discharged.
