Abstract: A method for detecting conditions within a space includes: accessing a corpus of object lists generated based on objects detected in images captured by a population of sensor blocks; compiling locations of a set of objects represented in the corpus of object lists into a map of the space based on known locations of the population of sensor blocks; accessing a nominal condition of the space defining a set of inclusion objects and a set of exclusion objects within a threshold distance of an anchor object type; and detecting the anchor object type in the map according to the nominal condition. The method further includes, in response to detecting an object within the threshold distance of the anchor object type in the map and deviating from the nominal condition: identifying the object as anomalous in the map; and generating a notification to investigate the object.

Abstract: Techniques for including and sharing crowd-sourced questions in online polls include a method with the steps of, in response to a client request for content, selecting from a repository of poll questions at least one poll question associated with the requested content and providing to the requesting client the requested content and a poll allowing a user to respond to the at least one selected question; receiving from the client a poll question generated by the user, the poll question including at least a question associated with the content and a plurality of answers responsive to the question; storing the received user-generated question in the repository of poll questions; and, in response to a subsequent request by a different client for the same content, selecting the user-generated question and providing to the different requesting client the requested content and a poll including the user-generated question.
