Each projection has a top intersection where the top edge of the first surface intersects the top edge of the second surface. Adjacent projections have a bottom intersection where the bottom edge of the second surface of a first one of the adjacent projections intersects the bottom edge of the first surface of a second one of the adjacent projections. The lens portion is opaque at the top intersection of the projections, at the bottom intersection of adjacent projections, and on the first surface between the top intersection and the bottom intersection. | 05-21-2015 |

20160054537 | Protection and Assembly of Outer Glass Surfaces of an Electronic Device Housing - Improved housings for electronic devices are disclosed. An electronic device housing can make use of at least one outer member (e.g., cover) that can be aligned, protected and/or secured with respect to other portions of the housing for the electronic device. In one embodiment, an electronic device housing can have one or more outer members (e.g., exposed major surfaces), such as front or back surfaces, that are formed of glass. Protective sides can be provided in some embodiments to protect the edges of the one or more glass surfaces so as to dissipate impact forces and thus reduce damage to the electronic device housing. The one or more glass surfaces can be part of outer member assemblies that can be secured to other portions of the electronic device housing. The electronic device can be portable and in some cases handheld. | 02-25-2016 |
20160062077 | IMAGING LENS ASSEMBLY - An imaging lens assembly includes, in order from an object side to an image side: an aperture stop; a first lens having a positive refractive power; a second lens having a negative refractive power; a third lens having a positive refractive power; a fourth lens having a negative refractive power. A focal length of the imaging lens assembly is f, a focal length of the first lens is f | 03-03-2016 |
20160084997 | MICROLENS ARRAY SUBSTRATE - A microlens substrate has a tendency to warp when an oxide film is formed and annealed before forming a mask in order to adjust the etching rate of wet etching. A film exerting a stress that cancels out this warping may be formed upon a microlens. This film functions as an optical path length adjusting layer. | 03-24-2016 |
20160131894 | AUTOFOCUS LENS SYSTEM - An autofocus lens system includes no conventional moving parts and has excellent speed and low power consumption. The system includes a small electronically-controlled focusing-module lens. The focusing-module lens includes two adjustable polymeric surfaces (e.g., two adjustable-surface lenses in a back-to-back configuration). The curvature of the surfaces can be adjusted to change focus. The performance of the autofocus lens system is extended by adding a conventional first and second lens, or lens group, on either side of the focusing-module lens. What results is an autofocus lens system with excellent near field and far field performance. | 05-12-2016 |
