Sempulse has developed a noninvasive vital signs sensor that adheres to the back of the ear and acquires patients’ five major vital signs—which the company says is an industry first—cuffless blood pressure, pulse oximetry, heart rate, respiratory rate and core body temperature, plus GPS and more.


The idea came from discussions with medics returning from Afghanistan about the need for new technology to triage casualties. Tree years of research,


NODAR INC.


NODAR, an early-stage, high-tech startup formed by Massachu- setts Institute of Technology alumni and located in the Boston area, builds optical 3D sensors for autonomous vehicles. Te company, which previously developed a laser vibrometer that operated from a moving ground vehicle, says its unique tech- nology outperforms the current lidar market in both reliability and safety, and that its robust, long-range technology operates in extreme weather conditions and temperatures.


NODAR’s system projects a continuous nonscanning laser array to measure range to objects by triangulation. Te proprietary laser array and optical receiver filter are optimized for performance across a range of distances and in varying types of light, from darkness to broad daylight. NODAR, whose name comes from

“native optical detection and ranging,” is a solid-state camera/ projector-based system with no moving parts and inexpensive standard and proprietary components. Te company touts its high reliability and durability as well as its ability to operate in a wide range of environmental and atmospheric conditions. Appli- cations for these characteristics include self-driving consumer, commercial and industrial vehicles.


For the xTechSearch proof-of-concept capstone event, NODAR will demonstrate its 3D sensor in harsh weather conditions such as rain, snow and hail, to show how the sensors would significantly enhance autonomous operation of the Army’s combat vehicles, supply vehicles and other robotic platforms.


development and testing led to the minia- ture device, which can easily be placed on most casualties to provide real-time moni- toring of vital signs. Instead of several minutes to triage a patient, the device allows for triage in seconds for multiple casualties and provides more care or a link to a remote physician. Te 30 hours of battery life allows monitoring to continue through and after transport.


The software has been optimized for medevac. An artificial intelligence and


machine-learning platform is designed to identify issues like internal bleeding. Sempulse has a simple goal: saving lives. Its platform is also finding interest from civilian markets, such as neonatal inten- sive care units, heart disease treatment and postoperative monitoring.


Sempulse is a component of the Mass- Challenge innovation ecosystem and the Texas Health Catalyst program.
