Abstract: An example method is performed at a device with a display and a biometric sensor. While the device is in a locked state, the method includes displaying a log-in user interface that is associated with logging in to a first and second user account. While displaying the log-in user interface, the method includes, receiving biometric information, and in response to receiving the biometric information: when the biometric information is consistent with biometric information for the first user account and the first user account does not have an active session, displaying a prompt to input a log-in credential for the first user account; and when the biometric information is consistent with biometric information for the second user account and the second user account does not have an active session on the device, displaying a prompt to input a log-in credential for the second user account.

Abstract: A method of thermally treating plastics material includes the steps of heating a treatment chamber at least to the melting point of at least a fraction of the plastic material, maintaining an oxygen level in the treatment chamber below combustion level of liquid or gaseous products from the plastic material, feeding the plastic material into the treatment chamber at a rate ensuring a built-up of a film of liquified plastic material on at least a part of the interior of the surface of the treatment chamber, with the liquified plastic material undergoing a transition into the gaseous phase as a result of the heating of the treatment chamber, and exiting of the gaseous phase out of the treatment chamber caused by vaporization pressure of the gaseous phase within the treatment chamber.

Abstract: A method for the pyrolytic production of synthetic gas from components of solid materials, including selected segregated post-consumed waste materials, within a pyrolytic gasifier operably heated by an associated furnace, which includes the steps of: preparing the materials for use as furnace fuel; preparing the materials for use as pyrolytically decomposable gassifier fuel by material proparation means; conveying the materials from the material preparation means to material segregation means by material conveying means operably associated therebetween; segregating the materials into selected segregated components of the gassifier fuel by the material segregation means; delivering the components of gasifier fuel into a desired gasifier fuel formula component ratio by gasifier fuel delivery means so as to comprise a gasifier fuel formula mixture; and compacting the gasifier fuel mixture by compacting means operably connected to gasifier fuel delivery means, so as to substantially eliminate entrapped oxygen and

Abstract: An energy system which burns refuse inside a steam chamber to drive a steam turbine and an electrical generator. In addition to the electrical energy produced, hot water and steam are delivered as by-products.
