    Abstract: A rotating shadowband for shading a pyranometer includes a cylindrical ring and a semicircular shadowband held within the cylindrical ring, a motor configured for rotating the shadowband, at least one solar panel, a rechargeable battery, and a controller having circuitry configured to power the first motor to rotate the semicircular shadowband. The semicircular shadowband may include a window opening, wherein the window opening substantially extends from a center of the band to a first end. The controller rotates the shadowband 0 to 360 degrees about the central axis of the cylindrical ring to alternately shade the pyranometer for making diffuse radiation measurements and expose the pyranometer to direct solar radiation for making global radiation measurements. Alternatively, the shadowband may be solid and rotate pivotally 0 to 180 degrees or 0 to 360 degrees within the cylindrical ring to alternately shade and expose a pyranometer head to and from direct sunlight respectively.

    Abstract: A method for discovering the topology of a connected lighting system. The method comprises: receiving a first measurement of a first light source in relation to a first sensor; receiving a second measurement of the first light source in relation to a second sensor; generating a first estimate of the position of the first light source, based on a first angle at the first sensor between (i) a first direction toward a current light source position and (ii) a second direction defined by the first measurement; generating a second estimate of the position of the first light source, based on a second angle at the second sensor between (i) a third direction toward the current light source position and (ii) a fourth direction defined by the second measurement; and generating an updated light source position of the first light source based on the first and second estimates.

    Abstract: The THz device module includes: a substrate; a THz device disposed on a front side surface of the substrate, and configured to oscillate or detect THz waves; a cap covering the THz device being separated from the THz device, and comprising an opening formed at a position opposite to the THz device in a vertical direction of the front side surface of the substrate; and a sealing member covering the opening of the cap so as to seal the THz device in conjunction with the substrate and the cap. A distance from the THz device to the sealing member is within a near-field pattern to which an electric field of the THz waves can be reached without interruption from a surface of the THz device to the sealing member. The THz device module efficiently emits or detects THz waves from the opening, thereby suppressing upsizing of the cap.
