This book presents new methods of circuit design for guitar
electronics, based directly upon U.S. Non-Provisional Patent
Applications. By systematic construction of unique series-parallel
circuit topologies, the author shows how many series-parallel
circuits are possible, including non-matched single-coil pickups,
humbucking pickups, and humbucking combinations of matched
single-coil pickups. This allows designers to avoid unnecessary and
confusing duplicate circuits in pickup switching systems. It shows
how electromechanical switches cannot produce the maximum number of
tones for more than 2 or 3 pickups. Thus the author discloses an
efficient micro-controller and cross-point switch architecture to
replace mechanical switches, and allow access to the maximum number
of tones. The discussion continues, developing humbucking circuits
for odd numbers of matched single-coil pickups, extendable to any
odd or even number, greater than 1, using a simplified switching
system with very simple rules. It abandons some tones in favor of
producing all-humbucking and unique tones, no matter what the
switching choice. The author discloses both mechanical and digital
switching versions. Then, based on using humbucking basis vectors,
the author discloses variable-gain circuits that duplicate all
possible switched humbucking tone circuits, and produces all the
continuous tone gradations in between. The presentation includes
analog and digitally controlled systems. The object of all the
disclosures: give the guitarist or pianist a system which allows
going from bright to warm tones and back, without ever needing to
know which pickups are used in what combination.
Of the three great civilizations of East Asia, Korea used to
attract the least attention. Overshadowed by their neighbours in
China and Japan, Koreans had trouble gaining recognition abroad for
the many accomplishments of their ancestors in such fields as
architecture, music, dance, and the arts. That has begun to change
in recent decades. As South Korea has gained economic power, people
outside of Korea have begun to notice that Korea's past is at least
as distinguished as its present. It is now possible to find good
English-language introductions to many aspects of Korea's ancient
culture. However, one area of Korea's culture has remained
relatively unknown - the beauty and extraordinary story of Korean
gardens has remained largely hidden from those outside Korea. This
book by Heo Kyun fills that gap. Heo Kyun shows in this book how
the gardens of Korea were distinctive, reflecting the beliefs and
values of the Korean scholars who designed them and enjoyed them.
Korea's traditional gardens, whether inside palace walls or in
mountain valleys, manifest the Korean desire to live in harmony
with nature. The gardens worked with nature, fitting into their
natural environment rather than drastically altering that
environment to satisfy human whims. Moreover, gardens provided a
sanctuary from the cares of everyday life. Koreans designed their
gardens to invoke the realms of the immortals they worshipped. When
they entered their gardens, the Korean literati, political exiles
and other recluses hoped to leave their worries behind them and
seek comfort in the natural beauty that surrounded them. With his
descriptions of the ideals behind Korea's traditional gardens as
well as depictions of many of the famous gardens, Heo Kyun takes us
into the worlds those scholars created, allowing us to summon, in
our own minds, their extraordinary beauty, tranquillity and power.
