The Dynamic PhotoDetector (DPD) tailored for hearables introduces an advanced level of precision in bio-signal monitoring, which is highly beneficial in achieving real-time metrics such as blood oxygen levels and heart rate. Traditional photodetectors require constant reverse bias and significant amplification to measure light intensity, a process that often introduces noise. However, ActLight's DPD innovatively shifts this process to measure delay time with a forward bias, enhancing signal quality without extra amplification. This technology offers tremendously high sensitivity, capable of detecting minute changes in light intensity. This ability allows it to function effectively in a range of light conditions—ideal for hearable devices that operate in varied environments. Whether used in fitness monitoring or in day-to-day wellness assessments, DPD in hearables offers reliable biometric data, making it a critical component for next-gen health-focused technology. ActLight's technology boasts low power consumption due to its operation solely on Vdd, eliminating the need for high voltage inputs and ensuring streamlined energy usage. Incorporating standard CMOS processes, it allows for straightforward integration into manufacturing procedures, reducing both costs and complexities while maintaining top-tier performance.
The Dynamic PhotoDetector (DPD) technology crafted for smart rings offers a leap in compact and efficient sensing for biometric applications. Unlike traditional fixed-bias photodiodes necessitating signal amplification, the DPD’s time-based measurement method with dynamic bias provides clarity without added noise. Its unique operation detects signal delays, reflecting precise light intensities, making it integral for miniaturized devices like smart rings. Built with high sensitivity, this technology is adept at capturing subtle light changes common in confined spaces, fundamental for accurately gauging heart rate or detecting physiological changes. Such precision ensures users receive detailed health metrics directly from their fingertip devices, enabling timely insights into their wellness. As it runs on low power (approximately 1V), the technology supports extended device use without frequent recharging, maintaining a steady performance across diverse environments. Supporting standard CMOS manufacturing techniques enhances its cost-effectiveness and ease of integration into production pipelines. This simplifies design processes while broadening possibilities for future device iterations, positioning DPD as a vital instrument in the development of smart wearable technology.
The Dynamic PhotoDetector (DPD) introduces a novel approach to light sensing, designed to enhance the capabilities of wearable devices. Traditional photodiodes measure light intensity via a constant reverse bias generating a photocurrent, often requiring amplification. In contrast, DPD operates by switching from reverse to forward bias, allowing light intensity to be inferred from delay time instead. This method reduces the need for analog amplification, significantly cutting down power consumption and noise, making it ideal for energy-efficient, long-lasting wearables like smartwatches and hearables. DPD technology is engineered for high sensitivity, tuning it to detect even single photons, which is crucial for accurate biometric readings such as heart rate and activity monitoring. Operating at low voltages around 1V, it minimizes energy use—essential for battery-powered devices that must deliver reliable, continuous performance. This precision and efficiency make the DPD highly suitable for health-focused applications, where consistent and accurate data gathering is paramount. The design also supports smart integration, using standard CMOS technology, making manufacturing processes simpler and cost-effective. Its compact size and high performance enhance device usability across various conditions, ensuring that wearables equipped with DPD technology provide an unparalleled user experience.
The Dynamic PhotoDetector (DPD) tailored for smartphone applications revolutionizes light sensing through innovative time-based technology. Traditionally, photodiodes required large setups with high amplification for reliable readings, but ActLight's DPD uses a dynamic forward bias approach, providing precision without heavy power demands or noise issues. By measuring delay times, this sensor captures light intensity effectively, streamlining power use for mobile applications. This DPD system proves indispensable for smartphone features like proximity sensing, ambient light adjustments, and advanced 3D camera functionalities. Its precise detection capabilities ensure user convenience, optimizing screen display settings and responding intelligently to surroundings without manual intervention. With its high sensitivity, it realizes clear imaging and powerful augmented reality applications, enhancing user interaction significantly. Engineered for integration using low-cost CMOS technologies, this detector facilitates seamless inclusion into existing mobile platforms, reducing overhead and production costs while maintaining exceptional performance levels. Its compact profile fits well with mobile device constraints, making it an ideal choice for manufacturers looking to push the technological envelope with modern smartphone capabilities.
