Abstract: Retroreflective elements and articles that include such elements. The retroreflective elements (100) include a solid spherical core (110) having an outer surface. A first complete concentric optical interference layer (112) overlays the outer surface of the core providing a first interface between the core and the first optical interference layer, and a second complete concentric optical interference layer (122) overlays the first optical interference layer to provide a second interface between the first optical interference layer and the second optical interference layer. In some embodiments, a third complete concentric optical interference layer overlays the second optical interference layer to provide a third interface between the second optical interference layer and the third optical interference layer.

Abstract: An apparatus for inflating and sealing packing cushions has a drive mechanism for feeding a preconfigured film material to a sealing mechanism in a flattened state without wrinkles in the sealing region in which a longitudinal seal is formed. In one aspect, the drive mechanism comprises a pair of upper adjacent belts and a backing element, such as a lower belt. The sealing mechanism may be a rotary sealing wheel that contacts the film material between the upper adjacent belts.

Abstract: A security laminate for authenticating an article and a method for authenticating articles is disclosed. The security laminate includes a transparent binder layer and retroreflective microspheres such that the security laminate exhibits a covert switching effect when exposed to particular conditions.

Abstract: A method, system, and computer program product for initiating a plurality of incident and service requests are provided. Outages are checked corresponding to the incident and service requests. If the outages exist, they are displayed and mapped to the incident and service requests. If the outages do not exist, they are created if required and mapped corresponding to the incident and service requests. The incident and service requests are assigned to users available in a shift for solutions. If the solutions corresponding to the incident and service requests exist in a knowledge database, they are implemented. If the solutions corresponding to the incident and service requests do not exist in the knowledge database, they are created by the users available in the shift. Various checks are performed based on a checklist prior to the closure of the incident and service requests.

Abstract: An apparatus, network and techniques for minimizing wireless network downtime associated with a wireless switch failure are disclosed. Access ports are adopted to multiple wireless switches wherein one switch operates to exchange data and control traffic with the access port and remaining switches operate to exchange control traffic with the access port. In the event of a link failure between the wireless switch exchanging data and control traffic with the access port, the access port remains adopted to remaining switches and exchanges data and control traffic with one of the remaining switches.

Abstract: Pavement markings having a substrate with a first major surface and a second major surface; and a plurality of retroreflective elements (100) disposed along the first major surface of the substrate, the retroreflective elements each having a solid spherical core (110) and at least a first complete concentric optical interference layer (120) overlying core. In some embodiments, the retroreflective elements of the pavement marking further include a second complete concentric optical interference layer overlying the first complete concentric optical interference layer. In still other embodiments, the retroreflective elements of the pavement markings further include a third complete concentric optical interference layer overlying the second complete concentric optical interference layer.
