Abstract: A LIDAR system includes an array of optical emitters, an objective lens optically coupling each optical emitter to a respective unique portion of a field of view, an optical switching network coupled between a laser and the array of optical emitters and a controller coupled to the optical switching network and configured to cause the optical switching network to route light from the laser to a sequence of the optical emitters according to a dynamically varying temporal pattern and to vary the temporal pattern based at least in part on distance to an object within the field of view. The LiDAR system scans different portions of the field of view differently, such as with different laser power levels, different revisit rates and/or different scan patterns, for example based on likelihood of detecting objects of interest in the various portions or based on likely relative importance of objects likely to be found in the various portions.

Abstract: A stackable tower planter includes a planter bucket having an open top and a hollow interior defined by a side wall and a bottom wall. The planter bucket includes a plurality of irrigation conduits that are disposed along an inner surface of the side wall. Each irrigation conduit has an open top end and an open bottom end that is disposed above the bottom wall of the planter bucket for delivering water to a water reservoir space located along the bottom wall. The stackable tower planter further includes a soil tray disposed within the hollow interior along a bottom of the planter bucket, with the water reservoir space being located below the soil tray. A water tray is coupled to a top edge of the planter bucket. The water tray has a plurality of drain openings that are fluid communication with a plurality of hollow bosses that are located along an underside of the water tray.

Abstract: In an embodiment, a method includes separating a heterogeneous radio-frequency (RF) signal, received at multiple antennas, into multiple homogenous signals. The multiple antennas have a known positional arrangement. The method further includes estimating a location relative to the known positional arrangement of the antennas of an object producing the RF signal based on phase and amplitude of each homogeneous signal as received at each of the plurality of antennas. The location can further be estimated over multiple time steps, such that velocity and acceleration can be accelerated from the estimated locations.
