Abstract: This patent advances a technique for the use of retroreflectors to prevent light pollution while radiating electromagnetic energy away from an object. As such, the patent defines how to do this on a surface, on a solar panel and with a communication device. It further investigates the communication device and makes it useful for relatively ad-hoc communication systems where aspects of the source and destination locations, distances, orientations and detection equipment is not known ahead of time.

Abstract: This patent amends Application 62/788,817. A method and system are disclosed or creating, reading, updating and deleting data in a datastore. The datastore uses ordered records called datastreams for propagating data records from multiple sources to multiple destinations with multiple formats. Datastores are also addressed and maintain ACID properties consisting of atomicity, consistency, isolation, durability, temporality and accumulation of data. A datastream consists of a series of complex records. Records may or may not contain multiple, overlapping subsets of records, called tuples, which are relevant to data domains, each tuple requiring a separate storage action.
