Abstract:
In an embodiment for use with a portable device, a haptic feedback system creates a haptic pop effect and the system may include a mechanism configured to produce a haptic pop effect and a controller electronically coupled with the mechanism to selectively activate the mechanism. In one example, the mechanism has a first normal state having mechanical energy stored therein, and a second state wherein said mechanical energy is released, thereby creating the haptic pop effect. The mechanism may include a material portion configured as a dome-shaped or arcuate diaphragm and made of metal that stores mechanical energy therein. A conductor such as a Nitinol wire may be positioned about and bonded to the perimeter of the material, and has a variable length of a first length to a shorter second length in response to the signal being applied to the mechanism. In this manner, the controller provides an electrical signal to the mechanism, and the mechanism responds to the electrical signal by activating the haptic pop effect. This effect is felt by the user of the electronic device.
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. Force sensors may be mounted under each of the four corners of the rectangular planar touch pad member. The force sensors may be used to measure how much force is applied to the surface of the planar touch pad member by a user. 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:
A system includes a band, an attachment mechanism attached to the band, and one or more haptic devices included in the attachment mechanism. The attachment mechanism can attach the band to an electronic device. Additionally or alternatively, the attachment mechanism can attach the band to a wearer. The haptic device or devices are in communication with a processing device. At least one of the one or more haptic devices produces a haptic response based on an activation signal received from the processing device.

Abstract:
In an embodiment, an actuator or circuit includes elements moveably coupled via bearings positioned between curved grooves. The bearings and the curves may exert a restorative force to return the elements to an original position after movement and may be spherical, cubic, cylindrical, and/or include gears that interact with groove gears. In some embodiments, an electrical coil may be coplanar with a surface of an element and a hard magnet may be positioned in the center and be polarized to stabilize or destabilize the element with respect to another element. In various embodiments, a magnetic circuit includes an element with an electrical coil wrapped in multiple directions around the element. In some embodiments, an actuator includes attraction elements and exertion of force causes an element to approach, contact, and/or magnetically attach to one of the attraction elements.

Abstract:
A display characterization system may be used to gather display flatness data and light leakage data from a display. The display characterization system may include a camera system that includes flatness measurement cameras and a light leakage measurement camera. The camera system may include a light guide plate covered with a patterned opaque layer or other planar light-emitting structures for emitting patterned light that is reflected from the display. A controller may use the light leakage measurement camera to capture light leakage data while a display backlight unit is on, a reference light source is on, and the planar light-emitting structures are not emitting light. The controller may use the flatness measurement cameras to capture flatness data while the backlight unit is off, the reference light source is off, and the light-emitting structures are reflecting light from the display.
