Abstract: A method for controlling a fluid-flow sensor in the presence of a flowing fluid, the method comprising: determining an initial estimate of a parameter corresponding to a flow rate of the flowing fluid, comparing the initial estimate to a threshold parameter, and based on the comparison, determining the parameter corresponding to the flow rate of the flowing fluid based on: a signal from a temperature sensor of the fluid-flow sensor; a signal from a heater of the fluid-flow sensor; or a combination of the signal from the temperature sensor and the heater of the fluid-flow sensor. A controller for a fluid-flow sensor is also described.

Abstract: A method for controlling a fluid-flow sensor in the presence of a flowing fluid, the method comprising: applying an electrical bias to the heater element of the fluid-flow sensor, determining a phase of the flowing fluid, and modifying the electrical bias according to the phase of the flowing fluid. A controller for a fluid-flow sensor is also described.

Abstract: The invention relates to an atomizer for an electronic smoking device, to a cartomizer with an atomizer and to an electronic smoking device with an atomizer. In order to improve atomizing efficiency, the atomizer comprises a heating coil made of a heating wire with a first section and a second section, wherein the first section comprises an electrical resistance per length unit that differs from an electrical resistance per length unit of the second section, and wherein the heating coil has a first winding, a last winding and at least one inner winding between the first winding and the last winding, wherein the at least one inner winding comprises the first section, the first winding comprises the second section, and the last winding ROM comprises a third section, wherein the electrical resistance per length unit of the third section corresponds to the electrical resistance per length unit of the second section.
