    Abstract: A camera attachment for measuring a temperature of a surface, and related methods of measuring the temperature of the surface, employ a temperature reactive material that is thermally coupled with the surface and imaged to provide image data of the temperature reactive material that is analyzed to measure the temperature. A camera attachment for measuring a temperature of a surface includes a distal surface configured to be thermally coupled with the surface, a frame configured to be coupled with a camera that has a field of view, and a temperature reactive material coupled with the frame and thermally coupled with the distal surface. The frame positions the temperature reactive material within the field of view of the camera so that an image captured by the camera includes at least a portion of the temperature reactive material.

    Abstract: A blood pressure cuff includes a support band that is selectively reconfigured between a flexible standby configuration and a measurement configuration. A blood pressure cuff includes an inflatable bladder, a support band, and a control unit. The support band is attached to and surrounds the inflatable bladder. The support band is reconfigurable, in response to an input from the control unit, from a standby configuration for between blood pressure measurements to a measurement configuration for constraining the inflatable bladder while the inflatable bladder is in an inflated state during a blood pressure measurement. The control unit includes a bladder pump for inflation of the inflatable bladder during a blood pressure measurement and controls the selective reconfiguration of the support band.

    Abstract: Embodiments are directed to systems and techniques for tracking menstrual cycles, which can include receiving temperature measurements from an array of temperature sensors positioned on a bed. A use period for the array can be determined when temperature measurements from at least one temperature sensor of the one or more temperature sensors exceed a first temperature threshold. In some embodiments, for each use period in a set of two or more use periods, a temperature of the user using the set of temperatures from the respective use period can be determined. After determining the temperature of the user for each use period in the set of two or more use periods, at least one change in the temperature of the user between different use periods can be identified. An ovulation day of the user based on the at least one change in the temperature of the user can be estimated.

    Abstract: Embodiments are directed to a blood pressure measurement device including a cuff that is operative to wrap around a limb of a user, a bladder coupled to the cuff and operative to compress the limb of the user when inflated, and a piezoelectric sensor coupled to the cuff and operative to detect blood flow through the limb of the user and output a signal indicative of the blood flow. The blood pressure measurement device can also include a processor coupled with the piezoelectric sensor that is operative to filter the signal to isolate sounds corresponding to changes in the blood flow through the limb due to inflation of the bladder, correlate the isolated sounds with a pressure inside the bladder, and determine a blood pressure of the user at least partially based on correlating the isolated sounds with the pressure.
