  • Patent number: 9256086
    Abstract: Electro-optic (EO) modulator and related device structures which can be used in conjunction with high EO materials to lower switching voltage and improve related performance parameters.
    Type: Grant
    Filed: February 3, 2014
    Date of Patent: February 9, 2016
    Assignee: Northwestern University

  • Publication number: 20150193813
    Abstract: An example involves determining a missing-audience factor based on first impressions corresponding to first client devices that do not have database proprietor (DP) identifiers for use by a DP to identify subscribers registered with the DP, and based on second impressions corresponding to second client devices that do have the DP identifiers used by the DP to identify subscribers registered with the DP. The first impressions represent accesses to media via the first client devices. The second impressions represent access to the media via the second client devices. The example involves determining a coverage-corrected unique audience (CCUA) size based on the missing-audience factor and a UA size of DP subscribers exposed to the media. The UA size is determined based on impressions logged by the DP. The CCUA size corresponds to impressions logged by the DP and not logged by the DP.

  • Publication number: 20150186403
    Abstract: Methods and apparatus to de-duplicate impression information are disclosed. An example method to de-duplicate media impression information includes determining an overlap between cookies of a first database proprietor and cookies of a second database proprietor on client computers; determining duplicate impression information based on first impression information associated with the first database proprietor, second impression information associated with the second database proprietor, and the overlap; and determining unduplicated impression information based on the duplicate impression information, the first impression information, and the second impression information.

  • Publication number: 20150095138
    Abstract: A disclosed example method to determine audience duplication in cross-media campaigns involves determining a first duplicated audience reach for a demographic group between a total television audience and an internet publisher audience. The total television audience is representative of audience members across a plurality of television networks. The internet publisher audience is representative of audience members of one of a plurality of internet publishers. The example method involves determining a second duplicated audience reach between the total television audience and the internet publisher audience for a media campaign based on the first duplicated audience reach. The example method involves determining a third duplicated audience reach between a television network audience and the internet publisher audience for the media campaign based on the second duplicated audience reach.

  • Patent number: 8582929
    Abstract: An electric field detection device. In one embodiment, the electric field detection device includes an interferometer having a reference arm and an active arm. The reference arm comprises a first electro-optic waveguide. The active arm comprises a first electrically conductive plate, a second electrically conductive plate spaced apart from the first electrically conductive plate defining a first gap therebetween, a third electrically conductive plate disposed in the first gap and vertically extending from the first electrically conductive plate to define a T-shape structure and a second gap between the third electrically conductive plate and the second electrically conductive plate, where the second gap is substantially smaller than the first gap; and a second electro-optic waveguide disposed in the second gap and being in electrical communication with the second and third electrically conductive plates.

  • Patent number: 8297821
    Abstract: Disclosed herein are a light source module and an electronic device using the same. The light source module is disposed in a housing component of the electronic device and includes a light source and a light guide element having a light-entering surface, a light-departing curved surface and a light-reflecting curved surface. The light-entering surface receives the light from the light source. The normal line directions of the light-departing curved surface are approximately perpendicular to the normal line direction of the light-entering surface. The light is reflected by the light-reflecting curved surface and then leaves the light guide element in the normal line directions of the light-departing curved surface.
