August 2018, a three-year-old toddler in Houston, TX suffered from heat strokes and hyperthermia after being left inside a hot car for over seven hours. The little girl’s father, instead of dropping her at the daycare, unknowingly left her in the back seat of the car and parked it behind the restaurant where he worked. Miraculously, the girl was conscious and survived the incident.

But not all children are this fortunate. In June 2019, an 11-month-old baby girl from Missouri breathed her last in a hot car after being locked inside for as long as 15 hours.

As unfortunate as they are, such incidents are very common in the U.S. According to a recent report by, a nonprofit child safety organization, on an average, 38 children die each year after being left in cars during hot weather, and out of them almost 87 percent are three years old or younger. This heart-wrenching situation leads to one question: “Is there a way to avert these incidents from occurring?”

With the help of Vayyar Imaging’s 4D sensors, the answer is yes! The eight-year-old Israeli startup offers sophisticated millimeter-wave 4D imaging radar sensors for automotive manufacturers. “By emitting low-frequency (RF) radio waves and detecting their reflections, our sensors analyze and identify the number of passengers present inside the car, build a real-time 4D image of each person, and monitor their vital signs and posture in real-time,” says Raviv Melamed, CEO of Vayyar. In case a child is left behind in the car, Vayyar’s sensors monitor the infant’s breath and alert the parent. Through this breakthrough technology, Vayyar is radically enhancing infant passenger safety in vehicles.

Recently, following the rise in hot car deaths, the U.S. House of Representatives introduced the Helping Overcome Trauma for Children Alone in Rear Seats (HOT CARS) Act of 2019, a bill that mandates all new cars to be equipped with a system that detects and alerts the presence of a passenger in the back seat when the vehicle is turned off. Driven by this decree, automotive companies are now challenged to quickly develop a technology that addresses this need. With Vayyar’s sophisticated 4D sensors already in the marketplace, carmakers can breathe a sigh of relief.

“Today, as the automotive industry transitions toward autonomous cars, our vehicles need accurate information about the external as well as the internal environment in order to understand everything that is happening around them better,” informs Melamed. This is precisely what Vayyar’s sensors are able to achieve.

Unlike cameras or other automotive sensors, our 4D sensors have the ability to distinguish objects even in the dark and extreme weather conditions, whilst maintaining 100 percent passenger privacy all the time

The radar on chip creates a moment-by-moment visual map covering passengers inside the vehicle as well as pedestrians and objects on the outside. So, if a driver is dozing off, the sensors can track the driver’s head movement and position, and send an alert to the emergency contact of the person, warning of potential driving mishap. Alongside, Vayyar’s sensors can also be used to remove blind spots of the vehicle, identify nearby obstacles, and provide perimeter information for self-parking. “Today, not only are we leaders in cabin safety but also pioneers in out of car sensors,” states Melamed. What truly talks for itself is the imaging solution’s ability to work even in bad lighting. “Unlike cameras or other automotive sensors, our 4D sensors have the ability to distinguish objects even in the dark and extreme weather conditions, whilst maintaining 100 percent passenger privacy all the time,” remarks Melamed. Adding to this list of benefits are four other factors that truly make Vayyar’s solutions unparalleled in the marketplace: their cost-effectiveness, energy efficiency, small size, and ability to detect objects within a wide range accurately.

Today, Vayyar’s 4D imaging sensors are opening new capabilities in various markets, including smart home, security, retail, and remote patient care. Going forward, the firm will continue to develop innovative 4D imaging solutions specifically for the public transportation domain. Vayyar has also established partnerships with tier-one companies such as Valeo, Faurecia, and Brose to build smart, tailored solutions that will improve the safety of passengers and vehicles. With a strong belief that 4D imaging sensors will play an important role in advancing the automotive industry, the firm is poised to lead the way with its state-of-the-art solutions.

Vayyar Imaging Wins Prestigious Clepa Safety Innovation Award

TEL AVIV, Israel - Vayyar Imaging, the global leader in 4D imaging radar, has won the SME Special Prize for Safety at the 2020 CLEPA Innovation Awards. Announced today, Vayyar triumphed with its game-changing 4D imaging radar-on-chip technology, which is revolutionizing the way the automotive industry addresses safety.

With road traffic accidents the single biggest cause of death and injury globally, automakers are intent on protecting both vehicle occupants and the rapidly growing number of Vulnerable Road Users (VRU). Safety, however, usually comes at a high price.

Evolving regulatory requirements are pushing up the complexity of automotive electronics and development costs. With as many as 200 sensors per car, electronics are expected to account for 50% of overall vehicle cost by 2030, encouraging industry leaders to reconsider the traditional one sensor per function paradigm.

Vayyar is in the vanguard of this change with its unique approach ” a multifunctional scale-ready platform ” which is driving a fundamental shift in how OEMs and Tier 1s engineer in-cabin and ADAS safety to provide high-end safety for all vehicles, including economy models which have previously been limited in life-saving features.

In-cabin and ADAS solutions have traditionally been seen as collections of safety features supported by numerous sensors powered by a range of technologies. Inside the car, Vayyars multifunctional 4D imaging radar platform allows automakers to embrace the concept of the cabin as a unified ecosystem in which just one high-performance RFIC supports multiple applications, such as Child Presence Detection (CPD) and enhanced Seat Belt Reminders (SBR). This cost-efficient combo functionality saves the cost of multiple sensors and programs. Outside the car, just 2-4 sensors support nearly a dozen ADAS and advanced parking assistance applications.

The key to multifunctional sensing is best-in-class imaging radar-on-chip technology providing both high resolution and an ultra-wide field of view. Supporting up to 48 transceivers, Vayyars solution generates 4D point cloud images for rich detection, tracking and classification data, while protecting user privacy. This enables the creation of highly advanced applications, without automakers having to overcome the hurdles of radar development. Precise and reliable, the sensors work regardless of line of sight, bad lighting or harsh weather conditions, for robust monitoring at all times across uSRR, SRR and MRR.

Vayyars platform also enables automakers to build additional applications for new models, or after vehicle deployment, to meet emerging safety demands over the same HW platform. The companys transformative technology, together with its pioneering, all-encompassing business model, create a comprehensive and validated offering that is the bedrock of its partnerships with a number of global auto brands and Tier 1 suppliers, helping them to reduce risk, costs and TTM.

Ian Podkamien, Head of Automotive at Vayyar Imaging, said: We are extremely proud that our unique, life-saving technology has been recognized by the automotive industry at the 2020 CLEPA Innovation Awards. By providing single-chip solutions that are multifunctional, cost-efficient and available now for mass production, were driving the mission of enabling our partners to protect all life on the road, so everyone can get to their destination safely.

CLEPA, the European Association of Automotive Suppliers, represents over 3,000 companies supplying state-of-the-art technology solutions, as well as more than 20 national trade associations and European sector associations. In its fifth edition, the CLEPA Innovation Awards celebrate outstanding achievements of mobility technology in the fields of Environment, Cooperation, Safety and Connectivity and Automation. Within each category a special prize is awarded to SMEs, acknowledging the role of small and mid-sized companies in the industrys achievements and a celebrating commitment towards making the future of mobility safer, smarter and more sustainable.
