摘要： To provide an indication of whether airflow is separated, as opposed to other states of flow, over a surface, two or more adjacent sensors at a location on the surface each produce an analogue signal representative of airflow. The analogue signals are correlated with each other, and the degree of correlation indicates whether the airflow is in a separated state. The correlation may be carried out by comparing processed values of the analogue signals, and thresholding the comparison result.

摘要： The invention relates to a device for determining and/or monitoring the mass flow rate of a gaseous medium through a conduit (2) or through a measuring tube. Said device has at least two temperature sensors (11, 12) and a control/evolution unit (10), both temperature sensors (11, 12) being located in a region of the housing (5) facing the medium (3) and being in thermal contact with the medium (3) flowing through the conduit (2) or through the measuring tube. A first temperature sensor (11) is configured so as to be heatable and a second temperature sensor (12) provides data on the actual temperature of the medium. The control/evaluation unit (10) determines the mass flow rate of the medium (3) using the difference in temperature (ΔT) between the two temperature sensors (11, 12) and/or using the heating capacity (Q) fed to the first temperature sensor (11). The control/evaluation unit, using at least one additional process variable (p, T, v) of the flowing medium (3), determines a corrected value for the mass flow rate determined using the difference in temperature (ΔT) or the heating capacity (Q) and makes available a corrected value (Qmc) for the mass flow rate through the conduit (2) or through the measuring tube.

摘要： A microscale out-of-plane thermal sensor (10, 100). A resistive heater (12) is suspended over a substrate (14) by supports (16) raised with respect to the substrate to provide a clearance (20) underneath the resistive heater for fluid (22) flow. A preferred fabrication process for the thermal sensor uses surface micromachining and a three-dimensional assembly to raise the supports and lift the resistive heater over the substrate.

摘要： A control device (70) is disclosed for controlling a power supply (10) arranged to supply electrical power to a filament (Ra), the temperature of the filament (Ra) being non-linearly dependent on power supplied to the filament (Ra). The control device (70) is arranged to receive temperature control instructions and to control the power supply (60) such that the temperature of the filament (Ra) is controlled in accordance with the instructions. The control device (70) is also arranged to take into account the non-linear relationship between the filament temperature and power input into the filament (Ra) so as to control the filament temperature in accordance with the instructions. The temperature control instructions are a function of a detected change in filament temperature and the control device (70) controls the temperature of the filament (Ra) such that the life of the filament is prolonged.
