Exhibit No. 1024 1025 1026 Description published July 24, 2008 U.S. Patent No. 5,807,267 to Bryars et al. issued September 15, 1998 Hyonyoung Han et al., Development of a wearable health monitoring device with motion artifact reduced algorithm, International Conference on Control, Automation and Systems, IEEE (2007) Excerpt from Merriam Webster’s Collegiate Dictionary, Eleventh Edition, 2008; p. 603 FITBIT, Ex. 1003
As discussed above, I believe a person of ordinary skill in the art would have recognized that configuring the processor of the Numaga-Vetter combination to process optical and motion signals to determine subject heart rate, FITBIT, Ex. 1003
For example, Fraden states that “[f]irst LED 71 emits light that in form of first beam 87 travels through the body of illuminator 65 which comes in physical contact 120 with the opening of the ear canal.
A person or ordinary skill in the art would have understood that an elastomer is a polymer with viscoelasticity (having both viscosity and elasticity) and very weak inter-molecular forces, generally having low Young’s modulus and high failure strain compared with other materials.
I believe a person of ordinary skill in the art would have found it obvious to integrate the housing of Fraden within an audio headset, as suggested by Verjus, to provide portable equipment that combines FITBIT, Ex. 1003
