Abstract: A post driver and remover for the installation and removal of posts includes a post receiver having a post receiver body having a driving end and an opposite driven end. The post receiver body defines a post receiving space having an open end adjacent the driven end and a closed end adjacent the driving end. The post receiving space is sized and shaped to receive an upper end portion of one of the posts. The post receiver body also has a first extractor and a second extractor. The first extractor receives a first post of a first cross-sectional size or shape, and the second extractor has a different size or shape from the first extractor to receive a second post of a second cross-sectional size or shape.

Abstract: Systems, methods, and computer-readable media are disclosed for estimating impressions for a digital out of home (DOOH) advertising spaces (e.g., digital billboards and screens). A DOOH advertising system may determine the location of relevant DOOH advertising spaces and the location of certain consumers with known attributes and a known location. Based on this information the DOOH advertising system may estimate a number of impressions for a given DOOH advertising space and a given consumer segment associated with attributes of consumers within a certain distance from the DOOH advertising space. Using this information, the DOOH advertising spaces having the highest estimated impressions for a given consumer segment may be identified.
