| Number | Title | Issue Date |
| 5563340 | Mass air flow sensor housing A mass air flow sensor housing for reducing backflow includes a U-shaped air flow path having an elliptical inlet and an outlet. A mass air flow sensor is positioned in the U-shaped air flow path. A converging ellipse inlet to the U-shaped air flow path r... | 10/08/1996 |
| 5537870 | Contaminant free backflow reducing insert for mass air flow sensors A housing structure for mass air flow sensors includes an auxiliary passage way, internal to the structure, that diverts a portion of the main air flow towards sensing elements. The sensing elements are shielded from the main air flow, so the contaminants... | 07/23/1996 |
| 5456101 | Apparatus for calibrating a mass air flow sensor using an oscillating air flow A method and apparatus for calibrating a mass air flow sensor in which the sensing elements of the sensor are subjected to an oscillating mass air flow summed with an offset mass air flow to produce the summed mass air flow. The output waveform of the mas... | 10/10/1995 |
| 5390528 | Method and apparatus for calibrating a mass air flow sensor using an oscillating air flow A method and apparatus for calibrating a mass air flow sensor in which the sensing elements of the sensor are subjected to an oscillating mass air flow summed with an offset mass air flow to produce the summed mass air flow. The output waveform of the mas... | 02/21/1995 |
| 5383356 | Mass air flow sensor arrangement having increased dynamic range A mass air flow sensor arrangement that has a mass air flow sensor fixedly mounted on a sensor mount which is connected to the low pressure region of a downstream venturi. The sensor mount has an isolation air flow conduit in which is received the sensing... | 01/24/1995 |
| 5369990 | Remote mount air flow sensor A remote mount mass air flow sensor that has a mass air flow sensor fixedly mounted on a sensor mount. The sensor mount has an isolation air flow conduit in which is received the sensing head of the mass air flow sensor. The remote mount mass air flow sen... | 12/06/1994 |
| 5355726 | Housing for reducing back air flow to mass air flow sensors A housing structure for reducing back air flow to the mass air flow sensor of an internal combustion engine. The housing structure consists of a housing defining a main air flow passage therethrough. A bypass passage is provided in the housing parallel to... | 10/18/1994 |
