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. Thus, 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:
A polarized electromagnetic actuator includes a movable armature, a stator, and at least one coil wrapped around the stator. At least one permanent magnet is disposed over the stator. When a current is applied to the at least one coil, the at least one coil is configured to reduce a magnetic flux of at least one permanent magnet in one direction and increase a magnetic flux of at least one permanent magnet in another direction. The movable armature moves in the direction of the increased magnetic flux.

Abstract:
A method is provided for fabricating a bending beam sensor coupled to a touch input device. The method includes providing a bending beam. The method also includes placing a first strain gauge and a second strain gauge on a surface of the beam near a first end of the beam, and aligning the first strain gauge and the second strain gauge with the beam along an axis. The first end is attached to a base. The method further includes coupling the first strain gauge and the second strain gauge to a plate of the touch input device and electrically connecting the first strain gauge and the second strain gauge such that a differential signal is obtained from the first strain gauge and the second strain gauge when a load is applied on the plate of the touch input device.

Embodiments of the present disclosure provide a system and method for providing an output for an electronic device. In certain embodiments, an alert is output in accordance with a current alert mode, which are selected based on one or more environmental conditions. The environmental conditions may be detected using one or more environmental sensors. The alert can optionally include one or more of: an audio component, a haptic component and a visual component. One or more of alert components correspond to an aspect of the environmental condition detected by the one or more environmental sensors.
Abstract:
A haptic actuator may include a housing having a top and a bottom, and first and second permanent magnets carried by the top and bottom, respectively, of the housing. The haptic actuator may also include a field member carried by the housing. The field member may include a coil between the first and second permanent magnets, first and second ends, and a first mass between the first end and the coil, and a second mass between the second end and the coil. A first shaft may slidably couple the first mass to the housing, and a second shaft may slidably couple the second mass to the housing. The haptic actuator may also include a first set of biasing members between the first end of the field member and the housing and a second set of biasing members between the second end of the field member and the housing.
Abstract:
A haptic electromagnetic actuator for track pad is provided. The actuator includes an array of electromagnets with alternating South and North poles on a first end, each magnet comprising a metal core and an electrical wire around the metal core. The array of magnets is coupled to a base plate on a second end opposite to the first end. The actuator also includes an attraction plate at a distance from the first end of the array of the magnets such that the attraction plate moves toward the magnets when an electrical current flows through the electrical wire around the metal core and moves away from the magnets when the current becomes zero. The array of magnets is configured to form a uniform gap from the attraction plate.
