問１．次はオーディオコンテンツ配信に関するクレームです。日本語に訳してください。
1.

A method of identifying an audio content sample that originatesfrom an actual broadcast, including:monitoring a plurality of broadcast stations, fingerprinting andsaving the fingerprints of broadcast audio content in a database ofunidentified broadcast content as it is received;
accessing playlists, comprising portions of identified broadcast
audio content from the plurality of monitored broadcast stations, andfingerprints corresponding to the identified broadcast audio content;
receiving data representing sampled audio content from a portabledevice and searching for a match between fingerprints of the sampled audio
content and the fingerprints corresponding to at least parts of multiple
playlists, further including:upon finding a fingerprint match against the fingerprints
corresponding to a particular playlist for a particular monitored broadcast
station, reporting the particular monitored broadcast station as a source ofthe broadcast audio content, and a description of the broadcast audio content
back to the portable device; andupon not finding a fingerprint match against thefingerprints corresponding to any of the multiple playlists, further searchingfor a match of the fingerprints of the sampled audio content, against at least

one of: parts of the database of unidentified broadcast content from themonitored broadcast stations, to identify a source of the broadcast audiocontent; and a reference database of identified audio content not associatedwith a particular broadcast station, to identify the sampled audio content;
andreporting back to the portable device at least one of the source of thebroadcast audio content and the identity of the sampled audio content.
問２．次の英文は、レーザーを用いた位置測定に関する従来技術の説明です。
符号(Ａ）で囲まれた部分を日本語に訳してください（必要であれば、内容の正確さが担保される限りにおいて、一文を区切って二文で表現するなど、工夫を凝らしていただいて構いません）。
Measuring devices, which are implemented for progressive tracking
of a target point and a coordinative position determination of this point, cangenerally, in particular in conjunction with industrial surveying, besummarized under the term laser trackers. A target point can be represented
in this case by a retroreflective unit (for example, a cube prism), which istargeted using an optical measurement beam of the measuring device, inparticular a laser beam. The laser beam is reflected in parallel back to themeasuring device, wherein the reflected beam is captured using a capture
unit of the device.
（A）
An emission or reception direction of the beam is ascertained in thiscase, for example, by means of sensors for angle measurement, which areassociated with a deflection mirror or a targeting unit of the system. Inaddition, a distance from the measuring device to the target point is
ascertained with the capture of the beam, for example, by means of runtime
or phase difference measurement or by means of the Fizeau principle.
In addition, in modern tracker systems, a deviation of the received
measurement laser beam from a so-called servo-monitoring point is
ascertained on a sensor--increasingly as a standard feature. By means of thismeasurable deviation, a position difference between the center of a
retroreflector and the point of incidence of the laser beam on the reflector
can be determined and the alignment of the laser beam can be corrected or
tracked as a function of this deviation such that the deviation on the sensor
is decreased, in particular is "zero", and therefore the beam is aligned in thedirection of the reflector center. By way of the tracking of the laser beamalignment, progressive target tracking (tracking) of the target point can be
performed and the distance and position of the target point can be
progressively determined in relation to the tracker system. The tracking canbe implemented in this case by means of an alignment change of thedeflection mirror, which is movable by a motor, provided for deflecting thelaser beam and/or by a pivot of the targeting unit, which has thebeam-guiding laser optic.

問３．次の英文は、いわゆるＭＲＩに関するものです。添付のＦＩＧ．１を参照しつつ、文章全体を日本語に訳してください。
Here, a basic field magnet 10 of the magnetic resonance device 9
generates a temporally constant strong magnetic field for polarization ororientation of the nuclear spin in an examination region of an examination
object 11, for example a human body, which while lying on an examinationtable 12 is pushed into the magnetic resonance device 9 for the examination.
The high level of homogeneity of the basic magnetic field 10 needed for thenuclear spin resonance measurement is defined in a typically sphericalmeasurement volume M, into which the examination object 11 is pushed.
To support the requirements for homogeneity and in particular to eliminate
temporally invariable influences the magnetic resonance device comprises
so-called shim sheet materials 9 made of ferromagnetic material at asuitable point.

Temporally variable influences are eliminated by shimcoils 13 if they are not desired. These are also used when generating
nonlinear gradients.
The basic field magnet 10 is likewise used as an enclosure for acylindrical gradient field system 14 of the magnetic resonance device 9,
which comprises three partial windings. Each partial winding is supplied byan amplifier 17 of the magnetic resonance device 9 with power for generating
a linear gradient field in the respective direction of the Cartesian coordinates
system. The first partial winding generates a gradient Gx in the x direction,
the second partial winding a gradient Gy in the y direction and the third
partial winding a gradient Gz in the z direction.
