Patent number: 10842390Abstract: The present invention includes systems and methods directed towards a wearable device (100, 200) that can measure health parameters in two levels. The wearable device can measure a health parameter of a user using an attached sensor (112). This sensor measurement is checked against a threshold database (126, 146, 156) that details an action to be taken if the sensor measurement satisfies a health threshold. The health can be predetermined by the user or by a professional. This action can be a request to the user of the wearable device to move the wearable device to another part of his/her body so that the wearable device can gather a second sensor measurement that can provide more detail or context for the first sensor measurement. The wearable device can thus provide two levels of sensor data measurement, which it can store and synchronize to storage on a network/cloud service (104) or to another electronic device (102).Type: GrantFiled: February 3, 2016Date of Patent: November 24, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: John Cronin, Joseph George Bodkin
