  • Publication number: 20190282159
    Abstract: Approaches to determining a sleep fitness score for a user are provided, such as may be based upon monitored breathing disturbances of a user. The system receives user state data generated over a time period by a combination of sensors provided via a wearable tracker associated with the user. A system can use this information to calculate a sleep fitness score, breathing disturbance score, or other such value. The system can classify every minute within the time period as either normal or atypical, for example, and may provide such information for presentation to the user.

  • Patent number: 10282014
    Abstract: A system can include a display, a first device, and a second device all operatively connected to a controller. The first and second devices each use or share at least a portion of the display area. The controller is adapted to transmit during a pixel refresh time period of the display a first signal that is received by the first device. The first sync signal indicates a first time period in which a first operation can be performed in the first device. The controller is also adapted to transmit a second sync signal that is received by the second device indicating a second time period in which a second operation can be performed in the second device. The second time period can be during the pixel refresh time period or outside of the pixel refresh time period.

  • Publication number: 20190099093
    Abstract: An aspect of the disclosure pertains to a blood pressure measurement device and methods of controlling an inflation rate in a blood pressure measurement. 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 pressure sensor of the blood pressure measurement device is configured to obtain blood pressure measurements, and a pump of the blood pressure measurement device is configured to inflate the inflatable bladder and control an inflation rate by controlling at least one of a duty cycle, a voltage, or a drive frequency.

  • Patent number: 10219711
    Abstract: Some embodiments relate to a device, method, and/or computer-readable medium storing processor-executable process steps for processing a photoplethysmographic (“PPG”) signal in a monitoring device that monitors a property of blood flow. In some embodiments, the processing includes obtaining a first digital signal representing a detected light signal having a non-pulsatile (e.g., DC) component and a pulsatile component (e.g., AC). An offset control signal is generated from an estimation of the non-pulsatile component and a second digital signal is generated after subtracting the offset control signal from the detected light signal and applying a gain to the subtracted signal. A reconstructed signal is generated that is calculated from the gain and one or more of (i) the first digital signal, and (ii) the second digital signal and the offset control signal.

  • Patent number: 10168814
    Abstract: A force sensing device for electronic device. The force inputs may be detected by measuring changes in capacitance, as measured by surface flex of a device having a flexible touchable surface, causing flex at a compressible gap within the device. A capacitive sensor responsive to changes in distance across the compressible gap. The sensor can be positioned above or below, or within, a display element, and above or below, or within, a backlight unit. The device can respond to bending, twisting, or other deformation, to adjust those zero force measurements. The device can use measure of surface flux that appear at positions on the surface not directly the subject of applied force, such as when the user presses on a part of the frame or a surface without capacitive sensors.

  • Patent number: 10139959
    Abstract: A method of calibrating a force sensor that includes an input surface and an array of sensing elements. The input has a number of test locations and is deformable under applied force. The force sensor is mounted in a predetermined test orientation. For each test location of the plurality of test locations on the input surface of the force sensor a predetermined test force to the test location. An element calibration value is measured for each sensing element of the array of sensing elements of the force sensor. An (x, y) deformation map of the input surface of the force sensor corresponding to the application of the predetermined test force to the test location is determined based on the measured element calibration values.

    Abstract: Systems and methods related to piezoelectric based force sensing in touch devices are presented. One embodiment, for example, may take the form of an apparatus including a touch device having a deformable device stack and a piezoelectric element positioned relative to the deformable device stack such that the piezoelectric element deforms with the deformable stack. Deformation of the piezoelectric element generates a signal having a magnitude discernable as representative of an amount of force applied to the touch device.

  • Patent number: 9891759
    Abstract: Detecting force and touch using FTIR and capacitive location. FTIR determines applied force by the user's finger within infrared transmit lines on a touch device. A pattern of such lines determine optical coupling with the touch device. Capacitive sensing can determine (A) where the finger actually touches, so the touch device more accurately infers applied force; (B) whether finger touches shadow each other; (C) as a baseline for applied force; or (D) whether attenuated reflection is due to a current optical coupling, or is due to an earlier optical coupling, such as a smudge on the cover glass. If there is attenuated reflection without actual touching, the touch device can reset a baseline for applied force for the area in which that smudge remains. Infrared transmitters and receivers are positioned where they are not visible to a user, such as below a frame or mask for the cover glass.

  • Patent number: 9851828
    Abstract: A touch sensitive input system for an electronic device includes a deflection sensor configured to generate a deflection signal based on deflection of a control or sensing surface, and a processor in signal communication with the deflection sensor. The processor is operable to generate a deflection or displacement map characterizing displacement of the surface based on the deflection signal, and a force map characterizing force on the surface based on a transformation of the displacement map. The transformation may be based on a generalized inverse of a compliance operator, where the compliance operator relates the displacement map to the force map. The compliance operator is not necessarily square, and does not necessarily have a traditional inverse.
