Multi-touch surface stackup arrangement

A multi-layer cover for an electronic device having one or more of a sensor panel, a proximity sensor, an ambient light sensor, and a display device can include an outer hardcoat, a structural layer, an IR transmissive ink layer, a mask layer, and a backside hardcoat. The backside hardcoat can reduce cover warpage, enable full surface lamination of the cover to the sensor panel, prevent bubbles from forming in transparent windows in the cover, enable a wider range of functional inks to be applied in various layering orders to allow certain types of light to pass through while blocking others, and hide the sensors to provide a seamless, uncluttered visual appearance.

Frame with environment resistant members

A frame for improved moisture, decay and insect resistance includes frame members each possessing a short treated lumber member joined to a longer untreated lumber member so that the length of the overall board achieves a desired length with an acceptable amount of distortion. The untreated member may be treated but the treatment is not so invasive as to impart a high degree of warping. The treated member may have more or less treatment depending on the amount of distortion which is acceptable. Top and bottom boards connect the frame members to form a door frame.

Manufacturing method of electronic device package, electronic device package, and oscillator

A manufacturing method of an electronic device package includes: forming concave portions that later form the cavities in one surface of a cover substrate; forming a first metal film on the cover substrate on a surface opposite to the surface in which the concave portions are formed; forming a second metal film on the cover substrate on the surface in which the concave portions are formed; bonding a base substrate and the cover substrate together via the second metal film. It thus becomes possible to provide an electronic device package in which the base substrate and the cover substrate are boned together via the metal film in a stable manner by minimizing warping of the substrate even when the substrate is made thinner.

Apparatus for securing sheet metal panels for butt-welding with integral copper backing plate

A welding clamp uses opposing metal pieces to clamp two pieces of sheet metal together with a defined gap between panels for the purpose of welding, in this case, butt welding. The clamp has an integral copper backing plate to provide weld backing support and thermal dissipation to the metal for improved butt weld results. The integral copper backing plate adds stiffness to the adjoined panels while providing a solid non-weldable backing support to the panels being joined, reducing or eliminating weld blow-through.
