Abstract: Blocks or tiles can be magnetically connected in arbitrary arrangements or structures. Each block or tile comprises electric power conducting elements that enable conducting power within and between adjacent blocks or tiles when terminals of the blocks or tiles are brought into contact and held via magnetic attractive forces.

Abstract: Light mapping devices and systems for use in indoor or vertical farming are disclosed herein. In particular, a light detection device is provided that includes a plurality of light sensors configured for detecting light emitted from one or more light sources at distinct positions across a grow plane. The light detection device will also include a microcontroller and one or more signal routing circuit boards, or junctions, for making electrical connections between the light sensors and the microcontroller in a multiplex architecture to enable the microcontroller to cycle through and read the Lux values from each of the light sensors with sub-second frequency and in real-time. The light detection device may also be part of a light mapping system that converts the Lux values to PPFD and generates a heatmap of PPFD intensity at distinct locations across the grow plane.

Abstract: A double-sided push broom with a broom handle and a broom head with first and second clearing faces having different orientations relative to the broom handle whereby first and second clearing faces can be used selectively in a single tool. A broom head block can have a triangular cross section with the first and second clearing faces disposed in a V-shape formed by first and second legs of the triangular cross section, and a handle-engaging face formed by the third leg of the triangular cross section. The faces can be separated by an angle a less than 180 degrees, and the handle can bisect the angle ? to establish a pivot angle ? between each clearing face and a support surface. The clearing faces can have brush surfaces with bristles of different brush characteristics, such as one for clearing rough surfaces and one for clearing smooth surfaces.
