YAMAGATA, Japan, Nov. 13, 2012
YAMAGATA, Japan, Nov. 13, 2012 /PRNewswire/ -- Yamagata Casio Co., Ltd., a
manufacturing subsidiary of Casio Computer Co., Ltd., announced on November 13
that it has applied technologies accumulated through the production of Casio
products to develop an underwater transceiver that lets users enjoy spoken
conversation when scuba diving. Casio will display a prototype of the new
Logosease dive transceiver at the Diving Equipment and Marketing Association
Show 2012 in Las Vegas, the U.S.A., from November 14.

The Logosease is a transceiver that allows users to have spoken conversations
underwater, revolutionizing the diving experience by solving the problem of
communication limited to written signs and basic hand signals. With the
Logosease, which is small enough to fit into a pocket and attach to the strap
of a diving mask, divers can converse normally with the scuba regulator in
their mouths. Since a full-face mask or any other type of special equipment is
unnecessary, the Logosease lets leisure divers converse with ease.
-- Wireless communications enabled by ultrasound and bone conduction
The Logosease employs an ultrasound range of 32 kilohertz to enable wireless
communication between users within visual range underwater. Multiple divers
can each wear a transceiver and enjoy conversing in a group. The microphone
and speaker employ a bone conduction method, and the reception and
transmission modes can be switched by lightly tapping the device once.
-- Built-in digital speech conversion technology
The Logosease modulates garbled underwater speech and transmits it, making it
easier to hear using digital speech conversion technology* jointly developed
with Professor Tetsuo Kosaka of the Yamagata University Graduate School of
Science and Engineering. This technology makes it easier to hear the voiced
"n," "m," "b" and "p" consonants, which are difficult to pronounce when diving
because the nose is blocked by the scuba mask and the air-supplying regulator
is in the mouth.
-- Compact size with waterproof performance up to 180 feet
Yamagata Casio has applied technologies accumulated through the production of
Casio products to realize waterproof performance of up to 180 feet for this
transceiver. This is more than sufficient for the basic performance needed for
recreational diving, which is limited to a depth of 130 feet. Furthermore, the
Logosease is compact and lightweight, measuring 3.50x1.61x1.76 inches and
weighing 3.77 ounces, making it possible to attach to the strap of a diving
* Underwater voiced speech varies depending on the person and/or surrounding
conditions. Yamagata Casio does not guarantee that the Logosease will deliver
audible and comprehensible underwater speech.
