Expanding Our Field to Medical Device-
Related Business with Blood-Flowmetry Sensor
Technologies
Utilizing our optical disc pickup data-reading
technologies developed over years, Pioneer
has developed a highly efficient, low-cost “non-
invasive portable blood-flowmetry sensor device”
that can measure blood flow without making an
incision on the patient. Irradiating a laser beam
at the patient’s body, the red blood cells in the
skin capillaries scatter and reflect the laser beam,
making it possible to measure the volume of blood
flow and the blood flow waveform in response to
external stimuli. It is known that the flow volume of
blood carrying oxygen in the body, and blood flow
waveform monitoring, which is closely related to
autonomic nerve function, have a direct connection
to managing physical fitness and health—and
medical institutions are carrying out research in this
area. Pioneer is considering working with medical
equipment manufacturers to implement portable
blood-flowmetry sensor devices at an early date,
while at the same time we are expanding the scope
of our medical device-related business.
ATSC HDTV Mobile Reception Technology
Pioneer has developed high-definition television
(HDTV) mobile reception technology that is
compatible with the North American ATSC terrestrial
digital broadcasting standard. By applying a signal
demodulation processing algorithm to the latest
mobile reception technology, this is the first time
that it has become available to receive a terrestrial
digital signal while traveling at high speeds,
something that had proven difficult. Our exhibition
of this technology at the International CES, the
world’s largest consumer electronics tradeshow
held in the United States, in January 2012, received
considerable attention. We have already carried out
tests in moving vehicles in the United States, and
have confirmed that the technology is able to receive
HDTV signals with no distortion while moving at
high speeds. In addition to use in car TVs, Pioneer
is considering exploring the further development of
this technology to make it possible to view digital
broadcasts on tablet PCs and smartphones—
a mobile device segment experiencing growth in
demand—while traveling at high speeds.
