  • Publication number: 20170281024
    Abstract: Wrist-worn devices and related methods measure a pulse transit time non-invasively and calculate a blood pressure value using the pulse transit time. A wrist-worn device includes an accelerometer, a photo-plethysmogram (PPG) or a pulse pressure sensor, and a controller. The PPG or the pulse pressure sensor coupled to the wrist-worn device for detecting an arrival of a blood pressure pulse at the user's wrist. The controller is configured to process output signals from the accelerometer to detect when the blood pressure pulse is propagated from the left ventricle of the user's heart, process a signal from the PPG or the pulse pressure sensor to detect when the blood pressure pulse arrives at the wrist, calculate a pulse transit time (PTT) for propagation of the blood pressure pulse from the left ventricle to the wrist, and generate one or more blood pressure values for the user based on the PTT.

  • Publication number: 20170136246
    Abstract: A system for performing a neurostimulation trial comprises an external trial stimulator capable of delivering stimulation energy to a plurality of electrodes carried by one or more stimulation leads. The external trial stimulator is configurable to operate in a plurality of stimulation energy delivery modes to respectively emulate one of different neurostimulator types. The system may further comprise a programmer capable of configuring the external trial stimulator to operate in one of the stimulation energy delivery modes. The programmer may be capable of generating a first programming screen capable of allowing a first set of stimulation parameters to be defined for the first neurostimulator type, and a second programming screen capable of allowing a second set of stimulation parameters to be defined for a second neurostimulator type.

  • Publication number: 20170086743
    Abstract: A wearable electronic device includes a body, a housing component, a band operable to attach the body to a body part of a user, and a force sensor coupled to the housing component. The force sensor is operable to produce a force signal based on a force exerted between the body part of the user and the housing component. A processing unit of the wearable electronic device receives the force signal from the force sensor and determines the force exerted on the housing component based thereon. The processing unit may use that force to determine a tightness of the band, determine health information for the user, adjust determined force exerted on a cover glass, and/or to perform various other actions.

  • Publication number: 20170091415
    Abstract: In some implementations, a computing device can receive a prescription for a user from a medication container device. The container device can be encoded with the prescription and can transmit the prescription (e.g., medication schedule and dosage information) to the computing device. The computing device can schedule presentation of reminders for the user to take the prescribed medication according to the prescribed schedule. In some implementations, the computing device can detect when the user has taken the prescribed medication according to the prescribed schedule and cancel a scheduled reminder. In some implementations, the computing device can remind the user to take the prescribed medication when the computing device detects that the user is near the medication container device. In some implementations, the computing device can remind the user to take the prescribed medication when the computing device detects symptoms associated with the prescribed medication.

  • Publication number: 20170007183
    Abstract: A wearable device that attaches to a body part of a user via an attachment member operates in at least a connected and a disconnected state. One or more sensors located in the wearable device and/or the attachment member detect the user's body part when present. Such detection may only be performed when the attachment member is in a connected configuration and may be used to switch the wearable device between the connected and disconnected states. In this way, the wearable device operates in the connected state when worn by a user and in the disconnected state when not worn by the user.

  • Publication number: 20140213961
    Abstract: A system and method for introducing one or more stimulating drugs and/or applying electrical stimulation to the brain to treat mood and/or anxiety disorders uses an implantable system control unit (SCU), specifically an implantable signal/pulse generator (IPG) or microstimulator with one or more electrodes in the case of electrical stimulation, and an implantable pump with one or more catheters in the case of drug infusion. In cases requiring both electrical and drug stimulation, one or more SCUs are used. Alternatively and preferably, when needed, an SCU provides both electrical stimulation and one or more stimulating drugs. In a preferred embodiment, the system is capable of open- and closed-loop operation. In closed-loop operation, at least one SCU includes a sensor, and the sensed condition is used to adjust stimulation parameters.
