Abstract: A headwear assembly is disclosed having an oximetry sensor and a circuit assembly configured to measure pulse and oxygen level for a user during exercise and/or physical activity. The oximetry sensor is positioned in a front section of the headwear assembly, proximate to the forehead when worn. Other sensors can also be included with the headwear assembly, such as temperature, blood pressure, and so on. The headwear assembly is configured to securely conform about a user's head when worn, such that the oximetry sensor is positioned and effectively immobilized on the forehead above the eyebrows. The headwear assembly can further provide integrated functionality with an external electronic device, such as a smart mobile phone. The headwear assembly can include a wireless charger for charging a rechargeable battery disposed on the headwear assembly.

Abstract: A headwear assembly is provided that measures physiological changes, e.g., oxygen saturation, pulse, blood pressure, and body temperature of a user during physical exercise, to include athletic activities and other situations. The headwear assembly can provide integrated functionality with an external device such as a smart phone. The headwear assembly can be embodied in various configurations, e.g., stand-alone headband, cap, visor, or a helmet.
