Abstract: Vacuum-insulated glass (VIG) windows (10) that employ glass-bump spacers (50) and two or more glass panes (20) are disclosed. The glass-bump spacers are formed in the surface (24) of one of the glass panes (20) and consist of the glass material from the body portion (23) of the glass pane. Thus, the glass-bump spacers are integrally formed in the glass pane, as opposed to being discrete spacer elements that need to be added and fixed to the glass pane. Methods of forming VIG windows are also disclosed. The methods include forming the glass-bump spacers by irradiating a glass pane with a focused beam (112F) from a laser (110). Heating effects in the glass cause the glass to locally expand, thereby forming a glass-bump spacer. The process is repeated at different locations in the glass pane to form an array of glass-bump spacers. A second glass pane is brought into contact with the glass-bump spacers, and the edges (28F, 28B) sealed.

Abstract: Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate sheet.

Abstract: A method for fabricating a high-density array of holes in glass comprises providing a glass sheet having a front surface and irradiating the glass sheet with a laser beam so as to produce open holes extending into the glass sheet from the front surface of the glass sheet. The beam creates thermally induced residual stress within the glass around the holes, and after irradiating, the glass sheet is annealed to eliminate or reduce thermal stress caused by the step of irradiating. The glass sheet is then etched to produce the final hole size. Preferably, the glass sheet is also annealed before the step of irradiating, at sufficiently high temperature for a sufficient time to render the glass sheet dimensionally stable during the step of annealing after irradiating.

Abstract: Methods of forming a sheet glass product comprising a plurality of growth-limited glass bump spacers. According to the methods, a glass pane of the sheet glass product is irradiated with laser radiation to locally heat the glass pane at a plurality of spacer localities and induce growth of a plurality of glass bump spacers in the glass pane. The growth of the plurality of glass bump spacers is limited by utilizing a growth-limiting plate comprising a scattering surface portion. The scattering surface portion of the growth-limiting plate mitigates damage to the growth-limiting plate and may also mitigate damage to the glass pane. Vacuum insulated glass products and systems for forming a growth-limited sheet glass product are also provided.

Abstract: A method of fabricating a high-density array of holes in glass is provided, comprising providing a glass piece having a front surface, then irradiating the front surface of the glass piece with a UV laser beam focused to a focal point within +/?100 ?m of the front surface of the glass piece most desirably within +/?50 ?m of the front surface. The lens focusing the laser has a numerical aperture desirably in the range of from 0.1 to 0.4, more desirably in the range of from 0.1 to 0.15 for glass thickness between 0.3 mm and 0.63 mm, even more desirably in the range of from 0.12 to 0.13, so as to produce open holes extending into the glass piece 100 from the front surface 102 of the glass piece, the holes having an diameter the in range of from 5 to 15 ?m, and an aspect ratio of at least 20:1. For thinner glass, in the range of from 0.1-0.3 mm, the numerical aperture is desirably from 0.25 to 0.4, more desirably from 0.25 to 0.

Abstract: A glass article having strengthened surfaces joined by at least one edge. The strengthened surfaces are under compressive stress. The glass article also has an inner region that is under a tensile stress of greater than about 40 MPa. The edge includes at least one fracture line that is parallel to the surfaces. A first portion of the edge is under compression and a second portion is under tension. The edge is formed by irradiating a glass mother sheet with a laser to form a damage line within the central region laser and separating the glass article from the mother sheet.

Abstract: A system and method for selectively enabling a feature of a controlled device. At least one feature on a controlled device is initially disabled. Content including a test is downloaded from a server to a mobile device. A user inputs into the mobile device background information and answers to the test. A score is generated based on the answers. If the score is high enough, a certificate is generated including release codes. The certificate is sent to the mobile device. The user may then place the mobile device in communication with the controlled device so as to forward the release codes and thereby enable the feature.
