Abstract: Devices, systems, and methods are provided for enhanced geographical caching of estimated arrival times. A method may include receiving respective user inputs indicative of respective users being in transit to a destination location from within a geographic region; determining, for the first user and the second user, a first estimated time of arrival from a first geographical area to the destination location, the first geographical area including the first location and the second location; identifying a third location of the first device at a third time, wherein the third location is within the first geographical area; determining that a time-to-live (TTL) of the first estimated time of arrival has not expired at the third time; and refraining from recalculating the first estimated time of arrival.

Abstract: Systems and methods of a monitoring node to assist an air navigation service provider (ANSP) in the design of an airspace. The monitoring node collects flight data and performs flight simulations for a large geographic region that is outside of the airspace. The monitoring node receives flight data collected by the ANSP for the airspace. The monitoring node supplements their flight data with the data received from the ANSP and performs flight simulations and generates flight plans for the airspace. The flight simulations and flight plans are transmitted to the ANSP which are then used by the ANSP to design the airspace.

Abstract: A door chime assembly with a transformer assembly mounted within an electrical box and proximately to a chime. The transformer assembly including a transformer operably coupled to a bracket. The transformer being insertable into the electrical box such that the bracket and electrical box cooperate to electrically isolate the transformer from the chime. The electrical box having mounting features for securing the door chime assembly in existing and/or new construction.

Abstract: A lighting module having at least a semitransparent cover and at least one light emitting diode oriented to emit light through the semitransparent cover. Each light emitting diode is positioned a minimum distance from an inner surface of the semitransparent cover.
