Abstract: Systems and methods improving three-dimensional sensor measurement accuracy are provided. For instance, an example apparatus can include a distance-estimation system, a distance-refinement system, and a processing system. The distance-estimation system can be configured to receive a first optical signal and determine a first distance between two points in an environment. The distance-refinement system can be configured to receive a second optical signal and determine a second distance between the two points in the environment. The processing system can be configured to receive information representing the first distance and the second distance and determine, based on the first distance and the second distance, a third distance between the two points in the environment. The difference between a true distance of the two points in the environment and the first distance can be larger than a difference between the true distance of the two points in the environment and the third distance.

Abstract: An electronic device may have display layers and other structures. A layer of liquid adhesive may be patterned onto a structure. The liquid adhesive may be pre-cured to increase the viscosity of the liquid adhesive and to partially shrink the liquid adhesive. The structure to which the liquid adhesive has been applied may be laminated to another structure. During lamination, the pre-cured liquid adhesive may be compressed between the structures that are being laminated. The adhesive may then be fully cured to bond the structures together. The thickening of the liquid adhesive during pre-curing helps control the spread of the adhesive. The shrinking of the liquid adhesive helps prevent stresses from developing that could lead to visible stress-induced artifacts following curing.

Abstract: One embodiment of method and apparatus for laminating a first substrate to a second substrate can use a liquid optically clear adhesive to form an initial contact area in addition to bonding the first substrate to the second substrate. When either the first substrate or the second substrate is relatively clear, the initial contact area can help reduce the introduction of bubbles or voids into a lamination region between the two substrates. In another embodiment, selected regions of a substrate can be treated to enhance the flow of the liquid optically clear adhesive, which can also reduce the introduction of bubbles and voids into the lamination region.
