Abstract: According to one embodiment, a solar device, comprises one or more photovoltaic cells disposed in an encapsulant and a light control structure including a louver film having a series of louver structures, wherein each louver structure includes one or more groupings of a plurality magnetizable particles aligned at least in a first orientation dispersed in a binding matrix. The light control structure substantially transmits light incident at a first angle and substantially limits transmission of light incident at a second angle. Each louver structure is spaced apart from an adjacent louver structure, wherein each louver structure is substantially aligned in a plane substantially parallel to an adjacent louver structure.

Abstract: A method of applying magnetizable particles onto an adherent web includes several steps. Step a) provides a magnetizable particle coating apparatus comprising a downward sloping dispensing surface at least partially disposed within an applied magnetic field. Step b) disposes an adherent web between upper and lower magnetic members and beneath the downward sloping dispensing surface, wherein the web comprises a backing having a curable binder precursor layer disposed on a major surface thereof. Step c) disposes magnetizable particles onto at least a portion of the downward sloping dispensing surface within the applied magnetic field, and subsequently disposed onto the curable binder precursor layer while the adherent web is advanced from an upweb position to a downweb position. Step d) at least partially cures the curable binder precursor layer to fix the orientations of the magnetizable particles.

Abstract: Techniques are described for monitoring and controlling fall protection equipment. For example, the techniques of this disclosure may be used to monitor the connection status of fall protection equipment, e.g., whether or not the fall protection equipment is connected to a support structure. The techniques described in the disclosure may determine whether the fall protection equipment is connected to a support structure based on changes in a resonant frequency of an electronic circuit of an inductive sensor within the fall protection equipment. The inductive sensor may be formed from sets of one or more coils, where a first set of one or more coils and a second set of one or more coils are wound in opposite directions.

Abstract: A data communication apparatus, system, and method are described. The data communication system comprises a transceiver disposed on an entrance port to an enclosure, such as an underground enclosure. The transceiver includes a housing, the housing mountable to the entrance port, wherein the transceiver is configured to communicate with a network outside of the underground enclosure. The data communication system also includes a monitoring device disposed in the underground enclosure that provides data related to a real-time condition within the underground enclosure. The data communication system also includes a sensor analytics unit to process the data from the monitoring device/sensor and generate a processed data signal and to communicate the processed data signal to the transceiver.
