corpus: private
form factor: shoe
creator: Nike, Inc. / Apple Inc.
disclosure: Nike, Inc. and Apple Inc. ‘Nike+iPod Sport Kit’, announced 23 May 2006 — an accelerometer pod that sits in a cavity in a Nike+ running shoe and transmits pace, distance, and calories wirelessly to an iPod nano.
ip status: patented
sensors: sensor-accelerometer
algorithms: algo-step-count, algo-activity-classification, algo-calorie-estimation
prior art notes: Discloses an accelerometer module integrated into the structure of a running shoe that derives pace, distance, and calories and transmits them wirelessly to a paired device. Anticipates instrumented-footwear claims combining ‘an inertial sensor housed in a shoe’, ‘derivation of gait/running metrics’, and ‘wireless transmission to a companion device’ from 2006. Anchor for the shoe/insole × accelerometer cross-cut on the product side; predates the smart-insole patent wave.
