Abstract: A haptic engine for measuring displacement of the haptic engine's mass uses a single sensing magnet that is carried by the mass along a driving direction. The haptic engine further uses two or more Hall-effect sensors, which are spaced apart (i) from each other along a direction parallel to the driving direction and (ii) from the single sensing magnet along a direction orthogonal to the driving direction, and are disposed adjacent to an ASIC that receives the sensors' output.

Abstract: A haptic actuator may include a housing, at least one permanent magnet carried by the housing, a field member movable within the housing and comprising at least one coil cooperating with the at least one permanent magnet, and at least one mechanical limit stop between the housing and the field member. The haptic actuator may also include circuitry capable of generating a pulse width modulated (PWM) waveform for the at least one coil to move the field member from an initial at-rest position and without contacting the at least one mechanical limit stop.

Abstract: A linear resonant actuator includes a ferritic tube, a movable mass, first and second flexures, and a set of one or more flexures. The ferritic tube has an axis extending from a first end of the ferritic tube to a second end of the ferritic tube. The movable mass has a set of magnet sections disposed along the axis. First and second flexures mechanically couple first and second ends of the movable mass to the ferritic tube. The flexures suspend the movable mass within the ferritic tube and allow movement of the movable mass along the axis. The electric coil(s) are attached to the ferritic tube and extend around the movable mass, between the ferritic tube and the movable mass. Each magnet section has magnetic poles disposed at different positions along the axis, and like magnetic poles of adjacent magnetic sections face each other.

Abstract: An electronic device may include a device housing and a haptic actuator carried by the device housing and that includes a haptic actuator housing and a field member movable within the haptic actuator housing. The electronic device may also include a motion sensor carried by the device housing to sense motion of the field member, an audio sensor carried by the device housing to sense audio noise from the haptic actuator, and a controller coupled to the haptic actuator, the motion sensor, and the audio sensor. The controller may be configured to drive the haptic actuator based upon sensed motion of the field member and audio noise from the haptic actuator.

Abstract: A notebook computer may include a display portion, a base portion, a hinge mechanism movably coupling the display portion to the base portion, an optical sensing system configured to capture an image of an object, an actuation system comprising a shape-memory alloy member coupled to the base portion and the display portion and configured to move the display portion relative to the base portion, and a processing system. The processing system may be configured to determine a target position for the display portion based at least in part on a location of the object in the image and cause the actuation system to actuate the hinge mechanism to move the display portion, relative to the base portion, from an initial position to the target position.
