Abstract: Apparatuses and methods that generate and send interactive elements to a plurality of wearable electronic devices are discussed. One or more mobile applications and one or more remote backend servers may cooperate to send information in the interactive elements to the instances of the time synchronous application resident in their wearable electronic device in order to bring different types of content such as timely and relevant data, events, and notifications to a user of that wearable electronic device without the user's intervention to actively retrieve the different types of content. The interactive elements may be generated and sent from any of i) a public application programming interface hosted on a server, ii) one or more mobile applications resident on one or more mobile computing devices, and iii) one or more remote backend servers. In addition, these sources may merely send content and commands for the interactive elements to the public application programming interface.

Abstract: A wearable computing device includes one or more processors, memory and a physiological metric sensor system, including a light source configured to direct light into tissue of a user wearing the wearable computing device, a light detector implemented a distance away from the light source and configured to detect light from the light source that reflects back from the user, and a light-blocking portion implemented between the light source and the light detector. The wearable computing device may further include an audio port directed towards an ear canal of the user and control circuitry configured to activate the light source during a period of time and generate a light detector signal indicating an amount of light detected by the light detector during the period of time.

Abstract: Assisted-GPS for a portable biometric monitoring device is provided. The portable biometric monitoring device may obtain updated ephemeris data from an associated secondary device via a short-range, low-power communication protocol. The secondary device may be a computing device such as a smartphone, tablet, or laptop. Various rules may control when the ephemeris data is updated. The ephemeris data may be used in the calculation of the global position of the portable biometric monitoring device. Additionally, the portable biometric monitoring device may communicate downloaded position fixing data to the associated secondary device. The associated secondary device may then calculate the global position from the position fixing data.

Abstract: Apparatuses, systems, and processes are discussed for using metadata to take action on an SMS message on a proprietary system. In some embodiments, a wearable electronic device has a wearable device application that can present an SMS notification from an SMS application of a mobile computing device. The wearable device application can provide SMS notification data to a partner application of the mobile computing device. The partner application can perform a reverse look-up in a contacts application of the mobile computing device and construct a first contacts list with potential SMS-message senders. The wearable device application can present one or more SMS-message actions to a user of the wearable electronic device for a user selection thereof. The partner application can communicate with a partner server, which, in turn, can communicate with an SMS provider to effect the user selection of the one or more SMS-message actions.

Abstract: Multiple circuits in a computing device can share one or more conductive elements. The use of the conductive element can vary by circuit, such as an antenna radiator for a radio frequency (RF) circuit or an electrode for an electrocardiography (ECG) circuit. The circuitry sharing a conductive element can utilize signals obtained over different frequency ranges. Those ranges can be used to select decoupling circuitry, or elements, that can enable the respective circuits to obtain signals over a respective frequency range, excluding signals over one or more other frequency ranges corresponding to other circuitry sharing the circuit. Such an approach allows for concurrent independent operation of the circuitry sharing a conductive element.

Abstract: Techniques for user identification by a biometric monitoring device are disclosed. In one aspect, a method of operating a biometric monitoring device may involve measuring a weight of a user in response to detecting that the user is standing on a platform, determining, based on sensor data generated by a sensor, a user parameter indicative of the user's identification, identifying one of a plurality of user profiles as corresponding to the user based on a comparison of the user parameter to parameter values and a comparison of the measured weight of the user to weight values, and updating the identified user profile based on at least one of the measured weight and the user parameter.

Abstract: A band latch mechanism that is configured to connect a wristband to a fitness tracker is provided. The band latch mechanism may be configured to be inserted into a cavity of a housing of the fitness tracker and configured so that any metallic body of the band latch mechanism does not contact metallic surfaces of the cavity in order to prevent an electrical ground from being positioned within a keep-out zone of an antenna of the fitness tracker. A housing with integrated antenna structures is also disclosed.

Abstract: Aspects of automatically detecting periods of sleep of a user of a wearable electronic device are discussed herein. For example, in one aspect, an embodiment may obtain a set of features for periods of time from motion data obtained from a set of one or more motion sensors in the wearable electronic device or data derived therefrom. The wearable electronic device may then classify the periods of time into one of a plurality of statuses of the user based on the set of features determined for the periods of time, where the statuses are indicative of relative degree of movement of the user. The wearable electronic device may also derive blocks of time each covering one or more of the periods of time during which the user is in one of a plurality of states, wherein the states include an awake state and an asleep state.
