Patent No. US12353244 (titled "Wearable Computing Device") was filed by Jpmorgan Chase Bank Na on Aug 30, 2024.
’244 is related to the field of wearable electronic devices, specifically those designed for continuous monitoring of a user's physiological data. The background acknowledges the increasing popularity of wearable electronics but highlights the limitations of existing devices, such as bulkiness and discomfort, which can hinder long-term wearability and accuracy. The patent aims to address these shortcomings by providing a compact and unobtrusive wearable computing device.
The underlying idea behind ’244 is to create a finger-worn ring device capable of continuously sensing physiological data. This is achieved by miniaturizing the necessary electronic components and arranging them within a ring-shaped housing. The key inventive insight is the realization that a ring form factor allows for prolonged, consistent contact with the skin, leading to more reliable and accurate data collection compared to traditional wearable devices.
The claims of ’244 focus on a wearable ring device with specific dimensional constraints (interior diameter between 12 mm and 24 mm, exterior diameter between 18 mm and 30 mm, a width between 3 mm and 8 mm, and a thickness between 1.5 mm and 3 mm). The device incorporates an external housing and an internal potting that encapsulates a curved battery, a printed circuit board, and several key components: an accelerometer, a temperature sensor, light-emitting diodes (LEDs) for emitting visible and infrared/near-infrared light, and light sensors for detecting the emitted light to measure heart rate and blood oxygenation.
In practice, the device works by emitting light into the user's tissue and measuring the reflected or transmitted light to determine heart rate and blood oxygenation levels. The accelerometer tracks physical movement, while the temperature sensor monitors skin temperature. All these components are integrated into a compact ring form factor, powered by a curved battery that maximizes space utilization within the housing. The transparent internal potting allows the LEDs to effectively illuminate the skin and the light sensors to accurately capture the returning light signals.
This design differentiates itself from prior approaches by optimizing for continuous wearability and accurate data collection. The ring form factor ensures consistent skin contact, while the miniaturized components and curved battery enable a comfortable and unobtrusive design. The use of transparent potting allows for efficient light transmission without requiring dedicated windows, simplifying manufacturing and improving the device's durability. The combination of multiple sensors in a single, compact device provides a comprehensive solution for monitoring various physiological parameters.
In the early 2010s when ’244 was filed, wearable computing devices were gaining traction, but hardware and software constraints made miniaturization and power efficiency non-trivial. At a time when activity monitoring was typically implemented using wristbands or clip-on devices, integrating a comprehensive suite of sensors and a battery into a small form factor like a ring presented significant engineering challenges. Furthermore, wireless communication and data processing capabilities were often limited by the available processing power and battery life, requiring careful optimization of algorithms and hardware components.
The examiner allowed the claims because the prior art (Drysdale et al. and Flake et al.) did not teach or suggest a wearable ring device configured to be worn on a finger that could sense physical movement, skin temperature, heart rate, and blood oxygenation levels. A key feature was the curved battery shaped to fit within the ring's housing, along with specific LEDs and light sensors positioned to measure physiological data through the skin.
This patent contains 20 claims, with claims 1 and 10 being independent. The independent claims focus on a wearable ring device with specific dimensions and components for sensing physical movement, skin temperature, heart rate, and blood oxygenation. The dependent claims generally elaborate on the features and functionalities of the wearable ring device described in the independent claims.
