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: Embodiments include wireless authentication devices, systems, and methods. A wireless authentication system can include an active wireless communication device including a first memory, first processing circuitry, and a first antenna, the first processing circuitry to produce an identifier request for an identifier (ID) and cause the first antenna to transmit the identifier request, receive the ID in a response to the identifier request, identify, based on the ID and data in the first memory, a location of a second memory to access, and produce an access request for the identified location of the second memory and cause the first antenna to transmit the access request. The system can further include a passive wireless communication device comprising a second memory, second processing circuitry, a second antenna, and a power harvesting circuitry to convert electromagnetic power incident on the second antenna to electrical power for the second memory and the second processing circuitry, the second processing circuitry to produce the response to the identifier request, the response including the ID, and cause the second antenna to produce the response, receive the access request, retrieve data from or write data to the identified location of the second memory based on the access request, and cause the second antenna to transmit the response to the access request.

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 method of aligning abrasive particles on a substrate. The method comprises providing a substrate. The method also comprises providing abrasive particles. The method also comprises generating a modulated electrostatic field. The modulated electrostatic field is configured to have a first effective direction at a first time and a second effective direction at a second time. The electrostatic field is configured to cause the abrasive particles to align rotationally in both a z-direction and a y-direction.
