Abstract: A device is disclosed for wearing on a wrist or other body part including a central piece held on the body part by a pair of straps. The proximal end of a strap includes a mounting pin for sliding into and out of a slot on the central piece. The proximal end of the strap further includes a positioning curve which mates with a correspondingly shaped receiving curve on the central piece when the strap is properly affixed and centered on the central piece. When properly affixed and centered on the central piece, the positioning curve on the strap aligns with the receiving curve of the central piece, so that the positioning and receiving curves are at their lowest energy state, resisting lateral movement out of a centered position.

Abstract: A user-wearable device include a wireless transceiver, a primary radiator antenna and a secondary radiator antenna. The primary radiator antenna produces a first radio frequency (RF) radiation pattern when driven by the wireless transceiver, wherein the first RF radiation pattern is at least partially circularly polarized. The secondary radiator antenna, which is spaced apart from the primary radiator antenna, is configured to modify the first RF radiation pattern produced by the primary radiator antenna to thereby produce a second RF radiation pattern having increased RF radiation in a specific direction (e.g., away from the user's/wearer's skin) compared to the first RF radiation pattern. Inclusion of both the primary radiator antenna and the secondary radiator antenna increases an overall antenna efficiency (e.g., by about 3 dB) in the specific direction compared to if only the primary radiator antenna was included.

Abstract: A user-wearable devices includes an on-body detector that uses one or more sensors of the device to detect whether or not the user-wearable device is being worn by a user. When the user-wearable device is detected as being worn by a user it is operated in a first mode, and when the user-wearable device is detected as not being worn by a user it is operated in a second mode that consumes less power than the first mode. Operating the user-wearable device in the first mode can include enabling wireless communication between the user-wearable device and a base station. Operating the user-wearable device in the second mode can include disabling wireless communication between the user-wearable device and a base station. Operating the user-wearable device in the second mode can also include disabling sensors of the user-wearable device and/or placing sensors of the user-wearable device in a low power mode.

Abstract: Technology is described for a wearable sensor system including an accelerometer and a PPG optical sensor having light processing elements including at least one photodetector in at least one linear configuration sharing an axis of orientation with the accelerometer. Heart rate measurements determined from reflected light detected by a photodetector of the light processing elements in a linear configuration are co-sampled with accelerometer measurements for one of its axes sharing its orientation with the linear configuration, thus providing per axis measurements which provide more precise data points for more easily compensating for motion artifacts in heart rate data. A wrist wearable biometric monitoring device is also described which embodies the wearable sensor system and performs active motion artifact compensation.

Abstract: Described herein are user-wearable devices that include an optical sensor, and methods for use therewith. In certain embodiments, an optical sensor of a user-wearable device (e.g., a wrist-worn device) is used to detect blue light that is incident on the optical sensor and to produce a blue light detection signal indicative thereof, and thus, indicative of the response of the user's intrinsically photosensitive Retinal Ganglion Cells (ipRGCs). In dependence on the blue light detection signal, there is a determination of a metric indicative of an amount of blue light detected by the optical sensor. The metric is compared to a corresponding threshold, and a user notification is triggered in dependence on results of the comparing, wherein the user notification informs a person wearing the user-wearable device to adjust their exposure to light.

Abstract: An activity monitor reduces power consumption by providing a heart rate sensor in an inactive mode at times when the heart rate is relatively unimportant. Data from a motion sensor is used to determine when to activate the heart rate monitor to obtain heart rate readings. For example, the motion data may indicate that the user is becoming active after a period of inactivity, or the user is vigorously exercising, then terminates the exercising, or the user is in a sleep-related activity such as the onset of sleep, non-REM (rapid-eye movement sleep) sleep, REM sleep and the user waking from sleep. The heart rate sensor may be in a continuously active mode, an alternating mode, or an inactive mode. In the alternating mode, a delay between readings is set adaptively based on the user's level of activity.

Abstract: An activity monitor determines whether the current value of a user's heart rate from a heart rate sensor is correct based on a motion-based heart rate and an associated spread which are determined by a model. The model provides a probability density function (PDF) of the heart rate based on confidence levels of previous heart rate values. The spread of the PDF is inversely proportional to the confidence levels. The confidence level may be based on an amplitude of a spectral peak relative to a noise floor. Multiple spectral peaks within the spread can be processed based on a shape of the PDF to determine which peak to use as the current value from the heart rate sensor. Either the value from the heart rate sensor or the motion-based heart rate is provided as the current heart rate.

Abstract: A processor for an activity monitor for a user has a reduced power mode in which it does not process data samples from an accelerometer. A wake up circuit or logic evaluates an output from the accelerometer and determines whether the output exceeds a threshold, indicating a threshold amount of activity of the user. If the threshold is exceeded, the wake up circuit or logic causes the processor to enter an active mode. The processor evaluates samples of the accelerometer in an evaluation period and decides whether to continue in the active mode or return to the reduced power mode. If the user is deemed to be sufficiently active, the processor continues in the active mode. In another aspect, the threshold can be set based on an activity level of the user before the reduced power mode or sensor data such as ambient light level or skin temperature.

Abstract: An activity monitor such as a wrist-worn device has an accelerometer which continuously detects motion of the user. The activity monitor also has an on-demand heart rate monitor which is activated by the user touching it from time to time. A calorie expenditure based on the motion of the user can be modified based on a heart rate measurement. Further, a determination can be made as to whether the user has made repetitive motions for a period of time. If the repetitive motions are detected, a calorie expenditure based on the heart rate is determined and compared to the calorie expenditure based on the user motion, and the higher value prevails. A situation is avoided in which the activity monitor underestimates the calories expended, such as when the user is exercising strenuously but the accelerometer indicates relatively little motion, e.g., during strength training.
