  • Patent number: 9208704
    Abstract: Hybrid signage capable of self illumination and having an active backlight. The signage includes a turning film having a structured surface for redirecting light in order to passively illuminate a printed graphic or shaped sign when the backlight is off. In the shaped sign, the shape provides the content, such as letters, to be conveyed to the viewer instead of a graphic. The signage can be actively illuminated when the backlight is on to supplemental the passive illumination.

  • Patent number: 9159540
    Abstract: The invention generally relates to systems and methods for transferring ions for analysis. In certain embodiments, the invention provides a system for analyzing a sample including an ionizing source for converting molecules of a sample into gas phase ions in a region at about atmospheric pressure, an ion analysis device, and an ion transfer member operably coupled to a gas flow generating device, in which the gas flow generating device produces a laminar gas flow that transfers the gas phase ions through the ion transfer member to an inlet of the ion analysis device.

  • Publication number: 20150232910
    Abstract: The invention relates to use of one or more bacteriophages in vivo in a human or animal in order to induce sensitivity to chemical antibiotics in bacterial cells, where such susceptibility is heritable, independent of continuing bacteriophage metabolism within those cells, and does not relate to the destruction of a biofilm to induce such sensitivity.

  • Patent number: 9064674
    Abstract: The present invention generally relates to a low temperature plasma probe for desorbing and ionizing at least one analyte in a sample material and methods of use thereof. In one embodiment, the invention generally relates to a low temperature plasma probe including: a housing having a discharge gas inlet port, a probe tip, two electrodes, and a dielectric barrier, in which the two electrodes are separated by the dielectric barrier, in which application of voltage from a power supply generates a low temperature plasma, and in which the low temperature plasma is propelled out of the discharge region by the electric field and/or the discharge gas flow.

  • Patent number: 9059306
    Abstract: Semiconductor devices that include a trench with conductive material for connecting a VDMOS device to a LDMOS device are described. The semiconductor devices include a substrate having a first region and a second region, wherein the second region is disposed on the first region. A trench extends from a top surface of the second region to the first region. The semiconductor substrate includes a VDMOS device formed proximate to the top surface of the second region and a LDMOS device that is also formed proximate to the top surface of the second region. The drain region of the VDMOS device is electrically connected to the source region of the LDMOS device by way of a conductive material disposed in the trench.

  • Patent number: 8919969
    Abstract: A system for on-product projection and display of electronic content. The system includes a projector for projecting electronic content, a mirror film stack having a reflective surface facing the projector, and a product having an exterior surface facing the reflective surface of the mirror film stack. A graphic is located on a surface of the mirror film stack opposite the reflective surface. The electronic content from the projector is projected onto the exterior surface of the product via the reflective surface of the mirror film stack. The graphic can be located on a display window and hide the mirror from a viewer without completely blocking a view of the projected electronic content. The product can include a removable projection screen for displaying the electronic content, and the projection screen can include a removable label on its non-viewer side to advertise or promote the product.
