Abstract: Methods, systems, and apparatus, including computer programs encoded on a storage device, for mapping an electrical grid are disclosed. A method includes sampling multiple locations within a geographic region, executing a detection process for each location, the detection process including applying the set of images for the location as input to a machine learning (ML) model that is trained to identify electrical grid assets depicted within images taken from a combination of different perspectives and obtaining an output from the machine learning model that indicates whether a same electrical grid asset is identified in each of the images of the location. In response to an ML output that indicates a positive identification of the same electrical grid asset being depicted in a particular set of images of a particular location, the method further includes: selecting a number of sublocations within the region, and executing the detection process for each sublocation.

Abstract: Disclosed herein is a device for supplying a plurality of crutches in use with a handmade smoking instrument. The device includes a business card divided into a perforated and on-perforated portions. The smoking instrument is typically a cylindrical smoking instrument created in the normal manner of rolling a handmade cigarette. The perforated portions are divided into a series of perforations, each perforation defining a strip, each strip defining a crutch. Upon removal, a perforated strip from the device, the strip is manipulated into the shape to fit within one end of the smoking instrument.
