PNI Sensor's Tiny Coprocessor for Wearables Solves the Missing Signal Problem for Pedestrian Tracking

CES 2016 Innovation Awards Nominee SENtrace Beats Standalone GPS: Saves Battery, Enables Accurate Pedestrian Navigation Across Environments

LAS VEGAS, NV--(Marketwired - Jan 5, 2016) - PNI Sensor Corp. today introduced CES® 2016 Innovations Awards Nominee SENtrace™, the first coprocessor for wearable devices that provides truly accurate, ultra-low power pedestrian tracking indoors, in urban canyons and in other environments where global positioning systems (GPS) signal goes missing or is inadequate.

SENtrace is a miniscule custom ASIC that uses just a trace of the power that GPS demands. Using PNI Sensor's proprietary embedded algorithms, it leverages existing ultra-low power inertial sensors to track users when there is little or no GPS signal. It also dramatically reduces overall battery consumption because it overrides and deactivates power-hungry GPS when it's not needed. In typical configurations, SENtrace uses one-tenth the power of GPS for computing each location point.

SENtrace provides tracking to one-meter accuracy over 100 meters traveled, supplying step-by-step data instead of extrapolations between two location points. That's a vast improvement over GPS, which tracks location to approximately 10 meters over 100 meters traveled.

"PNI Sensor has tapped more than two decades' experience in military-grade location-tracking for robots, humans in combat situations, and unmanned vehicles to develop SENtrace," said Becky Oh, president and CEO, PNI Sensor Corp. "We also have years of perfecting the highest-accuracy, lowest-power 9-axis sensor fusion for wearables and smartphones. SENtrace is the result of our combined expertise. It stays accurate over time and through a wide range of conditions, so its data can be trusted to deliver precise results in real-world scenarios. Wearables manufacturers will finally be able to offer proven pedestrian-tracking to consumers -- without having to worry about battery drain."

Potential Applications
"We foresee a range of applications for SENtrace in wearables," added Oh. "They include wrist-worn devices for locating lost children or elders and enhanced activity wristbands and smartwatches for athletes and fitness enthusiasts."

About the Technology
At just 1.7 x 1.7 x 0.5mm, SENtrace is a 32-bit processor with a custom floating point unit (FPU) embedded with PNI's sensor fusion tracking algorithms. These algorithms offload the tracking task from a device's main processor, thereby saving battery power.

SENtrace's algorithms work with any sensor manufacturer's sensors, allowing wearables original equipment manufacturers (OEMs) to select from a wide array of commercially available accelerometers, gyros and magnetic sensors.

CES 2016 Innovation Awards Honoree
SENtrace (code name: SENtral-PDR) has been named an Innovation Awards Honoree for CES® 2016 in the Embedded Technologies product category. The CES Innovation Awards program is an annual competition honoring outstanding design and engineering advancements across 27 consumer technology product categories.
