Abstract: A method may include designating, by a server, a designated geographic region and identifying a set of user accounts associated with mobile electronic devices located within the designated geographic region. The method may also include obtaining information from third party servers related to interactions of the user accounts with the third party servers. The method may also include receiving, from an advanced user account, a request for an automatically generated list of distinct geographic regions. The method may also include using a machine learning process to select geographic regions as the list of distinct geographic regions, the designated geographic region included in the list of distinct geographic regions based on the machine learning process acting on the information from third party servers and a quantity of user accounts. The method may also include transmitting the generated list to an electronic device associated with the advanced user account.

Abstract: A power meter (10) is provided which can plug into an electric wall socket and it is provided with its own socket (16) for receiving the plug of an electrical appliance. The power meter has means for measuring electric current flow to an electrical appliance and indicates the amount of electrical power consumed by an appliance. In alternative embodiments, the meter is provided as an integral part of an electric wall switch (30) or wall socket (40) or it is built into an electrical appliance (50). In another embodiment, the power meter has a plurality of sockets for receiving the plugs of a number of electrical appliances for separately indicating the power consumption of each appliance.

Abstract: An inhaler for medical aerosols includes a flow sensor 32 in the form of a piston which is movable against a spring bias 35 in response to inhalation. Movement of the piston unseats a valve member 30 allowing a pressurized dose to be released through a nozzle 67. A uniform impedance to the flow of air is provided throughout the movement of the piston to avoid any discontinuity in the flow. The apparatus is particularly suited for inhalers used in the treatment of asthma.
