Abstract: Technology is described for transferring one or more mobile tags using a light based communication protocol. A mobile device, for example a smart phone, with an image sensor and an illuminator, like a camera flash, initiates transfer of data formatted in a mobile tag displayed by another device by automatically controlling the illuminator to generate sequences of light representing data transfer messages. The other device, for example a user wearable computer device with sensors capturing biometric and health related data, has a photodetector unit for capturing the sequences of light and converting them into digital data. A processor of the other device identifies the data transfer messages and causes a display of one or more mobile tags responsive to the messages. In this way, a number of mobile tags may be used to transfer several kilobytes of biometric data, for example 4-7 KBs, using low power for the wearable device.

Abstract: A heart rate monitor determines a heart rate for a primary subject by reducing noise and cross-talk from unwanted signal transmission sources. A set of pulse peaks having about the same amplitude and an amplitude greater than any other set of peaks are processed to determine a subject's heart rate, while data having an amplitude below that of the set of peaks is ignored. To retrieve enough data to determine a peak amplitude, the signal having heart rate information is sampled at a frequency higher than a normal sampling frequency. In some embodiments, if no data is received for a set time period which is in or above the range, the threshold resets to zero under an assumption that the primary subject is no longer within transmitting range.
