Abstract: Disclosed herein are methods and systems for discovering an MSISDN of a cellular device, comprising detecting an activation event of the cellular device with a SIM associated with an MSISDN not exposed to the cellular device, transmitting one or more discovery Short Message Service (SMS) messages to a discovery system configured to transmit back to the cellular device one or more response SMS messages comprising the MSISDN identified for the discovery SMS message(s), receiving the response SMS message(s), and storing the MSISDN extracted from the response SMS message(s). The cellular device includes the stored MSISDN and a location of the cellular device in one or more Advanced Mobile Location (AML) messages transmitted by the cellular device to an AML service when initiating an emergency call.

Abstract: A method and a control system for a hot water supply system, wherein the hot water supply system includes at least one boiler having a heating fluid input pipe line, the control system comprising: a motorized valve; installed upon the heating fluid input pipe line; a first thermistor installed upon the heating fluid input pipe line; a second thermistor installed within the boiler; a motor mechanically connected to the motorized valve; and a controller, wherein the controller is adapted for opening and closing the motorized valve according to temperature difference between a temperature measurement by the first thermistor and a temperature measurement by the second thermistor, wherein the controller is electrically connected to the motor, to the first thermistor, and to the second thermistor.
