PRNewswire: ActLight, a Swiss company known for its Dynamic Photo Diodes (DPD), announces a project of next generation sensors for low energy heartrate sensing for wearable devices in co-operation with ON Semiconductor.
"The healthcare industry is becoming more reliant on new methods to monitor and treat patients. This - along with an increased interest in fitness and wellness - has necessitated more affordable, precise, wearable sensing options," commented Jakob Nielsen, Senior Manager Consumer Health Product Line at ON Semiconductor. "Today's smartwatches and wearables fall short of meeting customer requirements when it comes to heartrate measurement precision and application battery life time. Working with ActLight we will help to bring next generation heartrate sensors to the market that will address these requirements and deliver a full sensing solution for integration in a multitude of MedTech and consumer electronics applications."
"Our technology offers unique competitive advantages to our partners when compared to existing Photo Diodes used in wearable heartrate solutions," stated Serguei Okhonin, CEO of ActLight. "These include lower power consumption, simplified electronics and smaller footprint making it perfectly suited for miniaturized wearable devices. We are happy to see the support from ON Semiconductor and them sharing the potential of our technology in the area of heartrate sensing."

PRWeb: ActLight also announces a ToF sensor based on its DPD.
“ActLight’s ToF technology is pretty remarkable,” commented Jean-Luc Jaffard, Consultant & Advisor at Red Belt SA and a renowned authority on Imaging Technology and Applications (now with Chronocam). “The company believes that when used in range meters, it offers good immunity from the effects of background light, especially direct sunlight. Current optical sensors are often “blinded” by direct sunlight, an effect that likely led to some recent, highly publicized, vehicular accidents that occur while using Advanced Driver Assistance System (ADAS) cameras or when utilizing autonomous driving functions, and which hinders the adoption of autonomous driving altogether.”
Jaffard added, “ADAS and vehicle perception, autonomous vehicles and aerial drones are hot and emerging fields. ActLight’s ToF technology may be perfectly suited to supplement existing optical and computer vision technologies, thus help overcoming the hindrance of direct sunlight and other optical artefacts.”
“Our technology offers our partners some unique competitive advantages when compared to existing Avalanche Photo Diodes (APDs) and Single Photon Avalanche Diodes (SPADs),” stated Serguei Okhonin, CEO of ActLight, “these include low operation voltage, simplified electronics (due to high internal gain, there is no need for any amplifier as we directly interact with CMOS circuits), smaller footprint, and of course, lower price, making it perfectly suited for applications ranging from miniaturized wearable devices all the way to autonomous vehicles and areal drones. Our company is actively engaging with leading 3D imaging and silicon companies in evaluation and integration of our technology into their next generation sensors”.
The famous first killing by Tesla's pseudo-autonomous driving was not due to direct sunlight. Sun was behind the camera and lighting condition was excellent. There was no fault in sensing side. Problems lie in the brains of both man and machine.
