The neutral plane adjustment features may include a modified backfilm layer of the display in which portions of the backfilm layer are removed in a bend region. A display device may include a substrate, a display panel on the substrate having display pixels, and peripheral circuitry proximate the display panel and configured to drive the display pixels. A portion of the periphery of the substrate may be bent substantially orthogonal to the display panel to reduce an apparent surface area of the display device. The bent portion may include an electrode for communication with the peripheral circuitry.

Abstract: Electronic devices may use touch pads that have touch sensor arrays, force sensors, and actuators for providing tactile feedback. A touch pad may be mounted in a computer housing. The touch pad may have a rectangular planar touch pad member that has a glass layer covered with ink and contains a capacitive touch sensor array.

Processed force sensor signals may indicate the presence of button activity such as press and release events. In response to detected button activity or other activity in the device, actuator drive signals may be generated for controlling the actuator. The user may supply settings to adjust signal processing and tactile feedback parameters.

Abstract: This application relates to a low profile, small footprint cooling stack that does not extend substantially beyond a footprint of an integrated circuit to which it is affixed. The cooling stack utilizes a number of beam springs that supply a seating force to the integrated circuit by way of a metal slug. In some embodiments, a bottom surface of the metal slug can be contoured in accordance with a top surface of the integrated circuit and/or socket. In other embodiments a gap between peripheral portion of a bottom surface of the metal slug and an associated printed circuit board can be filled by a layer of foam to reduce auditory signals generated by the integrated circuit.

Abstract: Embodiments described herein may take the form of an electromagnetic actuator that produces a haptic output during operation. Generally, an electromagnetic coil is wrapped around a central magnet array. A shaft passes through the central magnet array, such that the central array may move along the shaft when the proper force is applied. When a current passes through the electromagnetic coil, the coil generates a magnetic field. The coil is stationary with respect to a housing of the actuator, while the central magnet array may move along the shaft within the housing. Titus, excitation of the coil exerts a force on the central magnet array, which moves in response to that force. The direction of the current through the coil determines the direction of the magnetic field and thus the motion of the central magnet array.

Abstract: Embodiments of the present disclosure are directed to a haptic actuator or a device having a haptic actuator that is capable of producing short, sharp and crisp pulses in a short amount of time.
