  • Publication number: 20140043169
    Abstract: A warning lamp has a base, a luminous module, a lampshade, and a reflector. The luminous module is mounted in the base and is located in a center segment of the base. The lampshade is combined with the base and has a lucent portion that is formed on a sidewall of the lampshade. The reflector is mounted in the lampshade and has a cone portion protruding toward the luminous module, a first surface facing the lucent portion, and a reflective portion formed on the first surface. The light emitted from the luminous module irradiates the reflective portion. The reflective portion reflects the light emitted from the luminous module to pass through the lucent portion. Accordingly, the warning lamp has a luminous effect in a circular form.

  • Patent number: 8465906
    Abstract: A photolithography mask including a plurality of mask features. Adjacent mask features are separated by a gap and are offset from each other such that individual mask features have one-side dense portions and two-side dense portions. Also a photolithography method that includes a step of providing a substantially opaque mask having N stepped rows of offset, substantially transparent, rectangular mask features, where N is an integer and N?2. The method also includes illuminating a photoresist layer located over an underlying material with dipole illumination through the substantially transparent, rectangular mask features in the substantially opaque mask to form 2N rows of exposed regions in the photoresist layer. The exposed regions have a substantially elliptical or substantially circular shape when viewed from above the photoresist layer.

  • Publication number: 20130120307
    Abstract: A handheld device includes a touch panel, a speaker, and a processor. The touch panel is operable to detect the touched area generated by an object touching the touch panel. The speaker is operable to provide sounds. The processor is connected to the touch panel and the speaker and controls the volume of the sounds provided by the speaker based on the touched area. The processor decreases the volume of the sounds when the value of the touched area is lower than a first predetermined value, and the processor increases the volume of the sounds when the value of the touched area is high than a second predetermined value. Furthermore, a method for controlling the handheld device is disclosed herein.

  • Patent number: 8394656
    Abstract: MEMS devices (such as interferometric modulators) may be fabricated using a sacrificial layer that contains a heat vaporizable polymer to form a gap between a moveable layer and a substrate. One embodiment provides a method of making a MEMS device that includes depositing a polymer layer over a substrate, forming an electrically conductive layer over the polymer layer, and vaporizing at least a portion of the polymer layer to form a cavity between the substrate and the electrically conductive layer.

  • Patent number: 8325529
    Abstract: Bit line connections for non-volatile storage devices and methods for fabricating the same are disclosed. At least two different types of bit line connections may be used between memory cells and bit lines. The different types of bit line connections may be structurally different from each other as follows. One type of bit line connection may include a metal pad between an upper via and lower via. Another type of bit line connection may include an upper via and lower via, but does not include the metal pad. Three rows of bit line connections may be used to relax the pitch. For example, two rows of bit line connections on the outside may have the metal pad, whereas bit line connections in the middle row do not have the metal pad.

  • Patent number: 8298847
    Abstract: Embodiments of MEMS devices include support structures having substantially vertical sidewalls. Certain support structures are formed through deposition of self-planarizing materials or via a plating process. Other support structures are formed via a spacer etch. Other MEMS devices include support structures at least partially underlying a movable layer, where the portions of the support structures underlying the movable layer include a convex sidewall. In further embodiments, a portion of the support structure extends through an aperture in the movable layer and over at least a portion of the movable layer.
