The extensive patent portfolio resides with the other half of the
business, Lewis said, but Redux has an exclusive license to exploit the
technology. The startup has also inherited the HIHS9002 chip, designed
for use with the company’s haptic exciters, which can be used to
position tactile feedback on a flat panel.
By applying these same
techniques to audible frequencies, Redux has products that turn a
screen or panel into a high quality, forward facing loudspeaker. The
technology is well suited to the latest toughened glass technologies
used in consumer products.
Known as 'Surface Sensation' it is
being targeted at flat-screen TVs, laptops, phones and tablet PCs, in
which it will replace internal micro speakers. However, the technology
also delivers top quality audio and compelling haptics from other
material surfaces including metal, plastics and composites.
thing we found is that every customer application is slightly different.
But we will continue use this [9002 chip] as the basis of a platform
while looking to expand on the control side with additional functions,"
said Lewis. "We are also developing new transducers. There is a strong
roadmap there so we move down that roadmap."
In terms of staffing
the company split has been more or less down the middle with 10 or 11
going to HiWave Audio and similar number to Redux, Lewis said. "We are
more focused on R&D engineering. We will be increasing the
engineering and business development strength over time," Lewis added.
are signs of rapid transition to haptics over the next couple of years.
Market research indicates that by 2015, 40 percent of tablet computers
will be haptic. We do see signs that embedded audio may come as a
precursor but our embedded audio is much better than a micro-speaker,"
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
