Abstract: An aspect of the disclosure pertains to detecting a position of a blood pressure measurement device. An inflatable bladder of the blood pressure measurement device defines, at least in part, a pressurizable volume. The inflatable bladder may be inflated to pressurize a user's appendage and temporarily occlude blood flow in the user's appendage. A pump may initiate inflation of the inflatable bladder when one or more accelerometers and/or one or more proximity sensors determine that the blood pressure measurement device is within sufficient proximity or elevation to a user's heart and stationary.

Abstract: Disclosed are devices and methods for non-invasively measuring arterial stiffness using pulse wave analysis of photoplethysmogram data.

Abstract: A radar-enabled device that manages radar interference. In particular, the radar-enabled device detects a radar signal transmitted by a second radar-enabled device, transmits a notification of the detected radar signal, receives localization information associated with the second radar-enabled device, and sets a device location based on the received localization information. Additionally, the radar-enabled device may adjust a timing of radar signal transmissions to avoid subsequent detections of radar signals transmitted by the second radar-enabled device.

Abstract: Systems and methods for continuous flow polymerase chain reaction (PCR) are provided. The system comprises an injector, a mixer, a coalescer, a droplet generator, a detector, a digital PCR system, and a controller. The injector takes in a sample, partitions the sample into sample aliquots with the help of an immiscible oil phase, dispenses waste, and sends the sample aliquot to the mixer. The mixer mixes the sample aliquot with a PCR master mix and diluting water, dispenses waste, and sends the sample mixture (separated by an immiscible oil) to the coalescer. The coalescer coalesces the sample mixture with primers dispensed from a cassette, dispenses waste, and sends the reaction mixture (separated by an immiscible oil) to the droplet generator. The droplet generator converts the sample mixture into an emulsion where aqueous droplets of the reaction mixture are maintained inside of an immiscible oil phase and dispenses droplets to the digital PCR system.

Abstract: Techniques and devices for a hierarchical framework of contexts for the smart home are described for managing modes in a smart home system by an electronic device. The electronic device receives a first input of a model for a second operational mode of a smart home system and receives a second input of the model for the second operational mode of the smart home system. Based on the first input and the second input, the electronic device determines an effective time interval for the second operational mode that is effective to cause the smart home system to transition from a first operational mode to the second operational mode during the effective time interval.

Abstract: This document describes systems and techniques directed at an altitude enhanced geofence. In aspects, a geofence manager maintains a three-dimensional virtual boundary for a geographic area associated with a user. The geofence manager determines a spatial positioning of a portable electronic device associated with the user relative to the virtual boundary. Based on a determination that the portable electronic device is within a horizontal boundary of the virtual boundary, the geofence manager monitors a barometric pressure surrounding the portable electronic device using information from at least one sensor associated with the portable electronic device. The geofence manager can determine an altitude of the portable electronic device based on the monitored pressure and initiate one or more functions if the altitude indicates the portable electronic device is within a vertical boundary of the virtual boundary.

Abstract: This document describes systems and techniques directed at autogenerated language model notifications. In aspects, a device management system associated with a network of network-connected devices includes a prompt manager. The prompt manager obtains metadata associated with the network and integrates at least portions of data from the metadata into one or more templated prompts to create an instantiated prompt. The instantiated prompt can be transmitted to a language model to generate a language model output. The prompt manager may then provide, based on the language model output, a notification to a user associated with at least one network-connected device. Through such a technique, the prompt manager can improve user experience and facilitate user proactiveness managing their network of network-connected devices.

Abstract: The disclosure provides BMDs that have multiple device modes depending on operational conditions of the devices, e.g., motion intensity, device placement, and/or activity type. The device modes are associated with various data processing algorithms. In some embodiments, the BMD is implemented as a wrist-worn or arm-worn device. In some embodiments, methods for tracking physiological metrics using the BMDs are provided. In some embodiments, the process or the BMD applies a time domain analysis on data provided by a sensor of the BMD for a first activity, and applies a frequency domain analysis on the data for a second activity, which contributes to improved accuracy and speed of biometric data.
