  • Patent number: 9430781
    Abstract: A network based indoor positioning and geofencing system and method is described. Beacons are disposed within a physical premises and each beacon transmits a signal containing identifying information. A networked indoor positioning module receives measured reference points that include a measured beacon identifier and a measured signal strength. The networked indoor positioning module uses the measured reference points to generate calculated signal strength values for at least one detected beacon. At least one geofence is associated with the physical premises and the geofence includes some of the calculated signal strength values. A wireless device receives a beacon identifier and a beacon signal strength, when the wireless device is in or near a geofence associated the physical premises.

  • Patent number: 9408032
    Abstract: A content delivery system, device and method is described. The content delivery system includes a database and a content presentation module. The database includes a user profile, user attributes, content items, and indoor geofences. The content presentation module presents a first list of targeted content items associated with a first user profile on a first wireless device. The first list of targeted content items corresponds to a first user attribute and a particular indoor geofence. The content presentation module also presents a second list of targeted content items associated with a second user profile on a second wireless device. The first list of targeted content items presented on the first wireless device is different from the second list of targeted content items presented on the second wireless device at the particular indoor geofence, when the first user attribute is different from the second user attribute.

  • Publication number: 20160190857
    Abstract: A tablet device charging mount apparatus is described, with related systems and methods, which allows for wireless charging of a tablet device mounted on a camera, and where it is contemplated that the tablet is operated in conjunction with the use and control of the camera. The mount comprises a wireless power transmitter which wirelessly charges a battery in the tablet device. It is contemplated that the wireless power transmitter may be electrically connected to an external power source which may be a dedicated battery, an external camera battery, and a camera internal battery. It is further contemplated that the power source may be integral to the mount apparatus. The wireless power transmitter may comprise a controller to automatically regulate the power requirements of the tablet. The charging mount apparatus allows the tablet battery runtime to match and potentially exceed that of the camera battery runtime without disconnecting the tablet from the camera.

  • Patent number: 9363940
    Abstract: A method of forming a plantable structure involves providing a substrate element, a release layer spaced from the substrate element, an adhesive layer disposed between the substrate element and the release layer, and at least one seed abutting the adhesive layer. The seed(s) is/are coupled to the substrate element through the adhesive layer. The method further comprises removing the release layer from the composite article, and adhering a remaining portion of the composite article to a secondary article. The remaining portion of the secondary article comprises the substrate element, the adhesive layer disposed on the substrate element, and the seed(s) abutting the adhesive layer. Also disclosed herein are a method of planting at least one seed with a composite article, a packaging structure, a method of forming a packaging structure, and a method of planting at least one seed.

  • Patent number: 9366851
    Abstract: Methods and apparatus are described for delivering index-matching immersion liquid in high numerical-aperture optical microscopy and lithography. An array of immersion liquid droplets is delivered to a specimen substrate or specimen substrate cover by an immersion liquid printing apparatus. An immersion liquid reservoir provides immersion liquid to the printer by a precision pump. The printer delivers immersion liquid to the substrate or substrate cover in arrays of immersion liquid droplets of defined volumes and array patterns. The volumes and patterns of array droplets delivered to the substrate or substrate cover are optimized to maintain adequate immersion liquid between the substrate or substrate cover and an immersion objective while avoiding the formation of air bubbles in the immersion liquid and the accumulation of excess volumes of immersion liquid.

  • Publication number: 20160054865
    Abstract: A system and method for map based exploration is described. The system includes a dynamic graphical user interface (GUI) that includes a list of targeted content elements for each different group profile, in which a first dynamic GUI corresponding to a first group profile that is served to a first user is different from a second dynamic GUI corresponding to a second group profile is served to a second user at approximately the same location, when the group profiles are different. A map is displayed on the touch screen display and the map displays a plurality of geofences. A geofence selection received by the touch screen display presents the dynamic graphical user interface that includes the list of targeted content elements for the particular group profile associated with the particular wireless device at the geofence selection.
