  • Publication number: 20170193563
    Abstract: Ad segments on a Web page are filled with ads that are served by a service provider operating between a user computer and publisher on one end and multiple ad serving entities on the other. The service provider implements a bidding process for the ad segment. The winning ad serving entity (DSP, ATD, advertiser, etc.) has its ad delivered to the user browser by the service provider where it is displayed in the Web page. The floor e-CPM for the ad segment is determined by the publisher using data related to the user (demographic, geographic, socio-economic, etc.), information on the ad segment (e.g., location on page), and relationships the publisher (e.g., a DSP having a relationship with the publisher may be offered a lower e-CPM). The service provider provides tools and highly granular information for the publisher in order to create an appropriate floor e-CPM for the ad segment.

  • Patent number: 8004281
    Abstract: Featured is a device for NMR or MRI signals from excited nuclei as well as related apparatus, systems and methods. The device includes a strip array antenna including one or more conductor and N reactive tuning components, where N is an integer ?1 at least one of the N reactive components is electrically coupled to each of the one or more conductors as well as to ground/virtual ground. The apparent electrical length of the conductors is tuned with the reactive tuning components so it is equal to be about n?/4, where n is an integer ?1 and ? is the wavelength of the signal to be detected. The length of the strip also is such as to be substantially in the approximate range of 1.3 times the depth of interest. The strip conductors are also combined with loop coils to form quadrature detectors.

  • Publication number: 20110056532
    Abstract: A method for fabricating a photovoltaic (PV) cell panel wherein each of a plurality of silicon donor wafers has a separation layer formed on its upper surface, e.g., porous anodically etched silicon. On each donor wafer, a PV cell is then partially completed including at least part of inter-cell interconnect, after which plural donor wafers are laminated to a backside substrate or frontside. All of the donor wafers are then separated from the partially completed PV cells in an exfoliation process, followed by simultaneous completion of the remaining PV cell structures on PV cells. Finally, a second lamination to a frontside glass or a backside panel completes the PV cell panel. The separated donor wafers may be reused in forming other PV cells. Use of epitaxial deposition to form the layers of the PV cells enables improved dopant distributions and sharper junction profiles for improved PV cell efficiency.

  • Publication number: 20080105355
    Abstract: Embodiments of invention are directed to the formation of microprobes (i.e. compliant electrical or electronic contact elements) on a temporary substrate, dicing individual probe arrays, and then transferring the arrays to space transformers or other permanent substrates. Some embodiments of the invention transfer probes to permanent substrates prior to separating the probes from a temporary substrate on which the probes were formed while other embodiments do the opposite. Some embodiments, remove sacrificial material prior to transfer while other embodiments remove sacrificial material after transfer. Some embodiments are directed to the bonding of first and second electric components together using one or more solder bumps with enhanced aspect ratios (i.e. height to width ratios) obtained as a result of surrounding the bumps at least in part with rings of a retention material. The retention material may act be a solder mask material.
