Apparatus, systems and methods for windows integration with cover glass and for processing cover glass to provide windows for electronic devices are disclosed. Transparent windows such as a transparent camera window, a transparent illuminator window and/or a transparent display window can be integrated into the cover glass. The apparatus, systems and methods are especially suitable for cover glasses, or displays (e.g., LCD displays), assembled in small form factor electronic devices such as handheld electronic devices (e.g., mobile phones, media players, personal digital assistants, remote controls, etc.). The apparatus, systems and methods can also be used for cover glasses or displays for other relatively larger form factor electronic devices (e.g., portable computers, tablet computers, displays, monitors, televisions, etc.).

A method of manufacturing a cover glass is provided. The method comprises providing a glass base; forming a glass support portion by printing glass onto the glass base; and applying glass wool onto the glass support portion.

An apparatus includes a fiber feeding system to deposit a fiber on an edge of the glass article and a laser system. The laser system is positioned to project a first and a second laser beam onto a first and a second side of the fiber, respectively. The laser system is positioned to project a third laser beam onto the edge of the glass article. A method includes advancing a glass article relative to a fiber; positioning the fiber in relation to an edge of the glass article, contacting a first side of the fiber with a first laser beam, contacting a second side of the fiber with a second laser beam, depositing the fiber on the edge of the glass article, and contacting the edge of the glass article with a third laser beam.

A glass composite includes a first glass member and a second glass member. The first glass member and the second glass member are at least partially connected with each other at the surfaces; and the glass composite has a light transmittance not lower than 95% of the light transmittance of the one, with the lower light transmittance, of the first glass member and the second glass member.

In a pressure-resistant glass sphere used for exploration of deep sea, ocean floor or the like, it is an important issue to reduce weight and increase a floating force while keeping pressure resistance capable of withstanding high water pressure of deep sea or the like and being used repeatedly. A pressure-resistant glass sphere of the present invention is composed of a pair of glass-made hollow hemispherical bodies, wherein the glass-made hollow hemispherical bodies are joined with each other at ground joint surfaces located on an equatorial plane of the pressure-resistant glass sphere so that the ground joint surfaces serve as a joining surface, and characterized in that a thickness of a spherical shell of the glass-made hollow hemispherical bodies is thicker at an equatorial plane portion than the portion other than the equatorial plane portion having a predetermined width from the ground joint surfaces.

A method includes placing a first part proximate a second part, disposing a sintering material in contact with both the first part and the second part, and applying energy to the sintering material to join the first part and the second part. An apparatus includes a first part, a second part, and an additively manufactured joint comprising a sintering material that joins the first part and the second part.

Various embodiments comprise a laser bonded glass-silicon vapor cell for performing spectroscopy on particles like atoms or molecules. In some examples, the laser bonded glass-silicon vapor cell comprises a glass base, a glass top, a silicon piece, and a filling material. The silicon piece comprises at least one through hole. The lower surface of the silicon piece is hermetically bonded to the glass base. The upper surface of the silicon piece is laser bonded to the glass top. The filling material is positioned in a cavity formed by the through hole, the glass base, and the glass top. The filling material may comprise an alkali metal, a salt slush, or an inert gas. In some examples the cavity formed by the through hole, the glass base, and the glass top may comprise a vacuum encapsulation.
