synthetic jet ejector or may cause an immediate failure such as a crack or tear in the normally flexible material of the diaphragm it has now been found that the foregoing issue may be overcome through the provision of a controller which operates in conjunction with a temperature sensor such that the synthetic jet ejector only turns on when the temperature sensed by the temperature sensor exceeds a predetermined threshold value advantageously the thermal management provided by the synthetic jet ejector is typically only needed when the sensed temperatures exceed such threshold values hence preventing the synthetic jet ejector from running until such temperatures are encountered not only overcomes the aforementioned problems but reduces energy consumption by the host device as well prior to further describing the systems and methodologies disclosed herein a brief overview of synthetic jet actuators may be helpful the structure of a synthetic jet ejector may be appreciated with respect to fig1 a the synthetic jet ejector 101 depicted therein comprises a housing 103 which defines and encloses an internal chamber 105 the housing 103 and chamber 105 may take virtually any geometric configuration but for purposes of discussion and understanding the housing 103 is shown in cross section in fig1 a to have a rigid side wall 107 a rigid front wall 109 and a rear diaphragm 111 that is flexible to an extent to permit movement of the diaphragm 111 inwardly and outwardly relative to the chamber 105 the front wall 109 has an orifice 113 therein which may be of various geometric shapes the orifice 113 diametrically opposes the rear diaphragm 111 and.
