Abstract: Structures and techniques are provided for shaping or steering a light field for an optical biological parameter sensor such that the light is partially or wholly collimated and enters a person's skin at an oblique angle to the person's skin such that the light has a direction component oriented towards or away from a photodetector of the optical biological parameter sensor.
Abstract: Physiological variables, metrics, biomarkers, and other data points can be used, in connection with a non-invasive wearable device, to screen for, and predict, mental health issues and cognitive states. In addition to metrics such as heart rate, sleep data, activity level, gamification data, and the like, information such as text message and email data, as well as vocal data obtained through a phone and/or a microphone, may be analyzed, provided user authorization. Applying predictive modeling, one or more of the monitored metrics can be correlated with mental states and disorders. Identified patterns can be used to update the predictive models, such as via machine learning-trained models, as well as to update individual event predictions. Information about the mental state predictions, and updates thereto, can be surfaced to the user accordingly.

Abstract: This disclosure provides devices and methods for estimating blood pressure using intelligent oscillometric blood pressure measurement techniques, where some implementations of the devices include multiple biometric sensors and/or can obtain sensor data from a connected device. In some implementations, the devices automatically determine an identity of a user. In some implementations, the devices automatically provide instructions to users to take blood pressure measurements. In some implementations, the devices applied intelligent inflation techniques to improve user comfort and speed up measurements.
Abstract: In one embodiment, a method for generating a message to a friend of a user is provided, comprising: processing activity data of a first user measured by an activity monitoring device to update a value of an activity metric for the first user; identifying a change in an inequality relationship between the value of the activity metric for the first user and a value of the activity metric for a second user; in response to identifying the change in the inequality relationship, prompting the first user to generate a message to the second user.

Abstract: Values of fields for a packet header can be analyzed to determine whether those values match default or expected values for those fields. If so, those values can be excluded or removed from the packet header. Flags are set to indicate whether or not a value is included for a given field, and if not then the default value should be used for that field. This compression helps to reduce the packet size, or at least allow for larger payloads within a minimum packet size. Approaches also provide for bi-directional communication capability, including the ability to initiate sessions from different devices, as well as to discovering other devices available for communication. Compression can also be used with address mapping to allow for address translation at the packet level, enabling multiple devices to communicate over a wireless channel that otherwise does not allow for concurrent communication sessions.
Abstract: Selecting and presenting messages to user of an activity/health monitoring platform. The health/activity monitoring platform may receive physiological data for a user. The health/activity monitoring platform may identify a set of messages based on the physiological data. The health/activity monitoring platform may also determine a set of scores for the set of messages. Each score from the set of scores may be associated with a message from the set of messages and each score from the set of scores may be indicative of whether a respective message should be presented to the user. The health/activity monitoring platform may also identify a first message from a set of messages based on the set of scores and cause the first message to be presented via a display of a computing device of the user. The health/activity monitoring platform may also update a first set of penalties associated with the first message in response to causing the first message to be presented.

Abstract: Techniques are disclosed, for intelligent management of multiple communications links. One communications link can be used to bring up another communications link with little or no user input. Selective enablement/disablement of one or more of the communications links is based on system needs and, other criteria. Utilizing one more-secure communications link to improve security on another less-secure communications link between the same devices is also contemplated.

Abstract: An activity tracking device is defined to detect and record movement of a person to which the activity tracking device is affixed. A secondary electronic device is defined separate from the activity tracking device. The secondary electronic device is defined to receive data from the activity tracking device regarding the detected and recorded movement of the person. A website is defined to communicate with connected devices including the secondary electronic device. The website is defined to provide a user account for the person. The website is defined to convey information regarding the detected and recorded movement of the person through the user account.
Abstract: Systems and methods for determining a sedentary state of a user are described. Sensor data is collected and analyzed to calculate metabolic equivalent of task (MET) measures for a plurality of moments of interest. Based on the MET measures and a time period for which the MET measures exceed a threshold value, it is determined whether the user is in a sedentary state. If the user is in the sedentary state, the user is provided a notification to encourage the user to perform a non-sedentary activity.

Abstract: Two devices can be connected for communication by a wireless connection, where those devices will function as master and slave devices with respect to that connection. A slave device to a connection can perform changes to the connection on behalf of an application, subsystem, or other such source on either the slave device or a master device. These changes can include changes to connection parameter values, or can include state changes such as to perform a disconnect action. Enabling the slave device to perform these actions can help to bypass any restrictions that would otherwise prevent these actions being performed from a master device to the connection.

Abstract: Some embodiments provide a wearable monitoring device including a motion sensor and a photo (PPG) sensor. The PPG sensor includes (i) a periodic light source, (ii) a photo detector, and (iii) circuitry determining a user's heart rate from an output of the photo detector. Some embodiments provide methods for operating a heart rate monitor of a wearable monitoring device to measure one or more characteristics of a heartbeat waveform. Some embodiments provide methods for operating the wearable monitoring device in a low power state when the device determines that the device is not worn by a user.
Abstract: Various antenna designs are presented that can be used to provide for wireless communication in electronic devices, such as wearable electronic devices. Various embodiments provide antenna structures and designs that can support multiple frequency bands in a relatively compact space. Various embodiments utilize a slot and patch antenna design to support multiple frequency bands. Other embodiments utilize a slot and inverted “F” antenna (IFA) assembly, hybrid slot antenna assembly, or external slot antenna assembly. A split ring antenna assembly can also be used, where individual segments of the ring antenna can support specific frequency bands. Other embodiments utilize a dielectrically loaded planar inverted “F” antenna (PIFA) assembly to support various frequency bands.
