    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.

    Abstract translation: 一种用于电子设备的力传感装置。 力输入可以通过测量电容的变化来检测，如通过具有柔性可触摸表面的装置的表面弯曲所测量的，导致在装置内的可压缩间隙处的挠曲。 响应于可压缩间隙的距离变化的电容式传感器。 传感器可以位于显示元件的上方或下方，或者位于背光单元的上方或下方或之内。 该装置可以响应弯曲，扭曲或其他变形，以调整这些零力测量。 该装置可以使用出现在表面上的位置处的测量，而不是直接施加力的对象，例如当用户按压在框架的一部分上或没有电容传感器的表面时。

    Abstract: Embodiments described herein are directed to a temperature measurement device that includes a sensor body configured to be placed on a skin of a user. The temperature measurement device can include a first section defining a first lower surface and having a first thickness, a second section defining a second lower surface and having a second thickness, and a channel separating the first lower surface from the second lower surface. The temperature measurement device can also include a first set of temperature sensors positioned across the first thickness, a second set of temperature sensors positioned across the second thickness, and a processor configured to estimate a tissue temperature of the user based on comparing temperature signals from the first set of temperature sensors with temperature signals from the second set of temperature sensors.

    Abstract: A sensor layer, such as a force sensor layer, can be in included in an electronic device. The sensor layer includes a patterned compliant layer that is positioned between a first substrate and a second substrate. The patterned compliant layer includes multiple angled compliant elements that are angled at one or more angles with respect to the first and second substrates.
