| An apparatus and method for adaptive materials arranged in a variety of orientations and with a wide range of attachment configurations to induce structural vibrations at extremely high frequencies. These mechanical vibrations cause fouling agents to become detached and accordingly “clean” an otherwise dirty element or wire of a hot-wire anemometer, planar or curvilinear sensor surface, or display surfaces. They also can be made to vibrate at such frequencies with such intensities that local droplets of water are either shaken off or instantaneously cavitate, thereby allowing the elements to be used in all weather conditions. | ||||||
| 132 | Equipment for measuring gas flow rate having an adjacent external surface protrusion | US12341426 | 2008-12-22 | US07752908B2 | 2010-07-13 | Shinya Igarashi; Hiroshi Kikawa; Yasuhiro Asano; Naoki Saito |
| In a flow sensor, detecting elements are provided at a sub-passage. A sub-passage wall contains a hole to drain accumulated liquid. A protrusion arranged close to the hole on an external surface generates dynamic pressure on the opening in response to external flow. Alternatively, a protrusion upstream from the hole on the inner wall surface produces a separation flow area for separating the flow from the internal surface near the hole, whereby pressure in the separation area is reduced and almost the same pressure differences on the internal and external surfaces openings result. This reduces leakage from the hole and changes in the distribution flow in the sub-passage between cases where the hole is blocked and not blocked, thus minimizing flow measurement errors. Structure may be provided close to the external surface hole opening to prevent a liquid film or drop from being formed on the opening by surface tension. | ||||||

The small holes are formed over the entire surface of the mesh member continuous with adjoining other small holes. The small holes of one mesh member and another mesh member adjacent thereto in the axial direction are arranged so as to have a phase angle difference of 90 degrees in the circumferential direction. | ||||||

| When it is predicted that an engine is going to be started in the near future, a heater portion of an air flow meter is energized so as to be heated in advance. Prior to the pre-heating, an intake air temperature is sensed by a temperature sensing portion of the air flow meter. After completion of start-up of an intake air temperature sensor, a difference between the intake air temperature sensed by the intake air temperature sensor and the previously sensed intake air temperature is obtained. When the difference is above a predetermined value, it is judged that the intake air temperature sensor or the air flow meter is in an abnormal condition. | ||||||

| The invention relates to devices and methods for reducing the contamination of a sensor with which a sensor or sensor element—preferably a hot film air-mass meter—is deactivated when a software function integrated in the electronic control unit detects a possible contamination or a media carry-in.

After the sensor is deactivated, a substitute signal is optionally generated that replaces the missing output signal of the sensor. | ||||||
