Did You Know...
...that while attempting to develop a super strong glue, 3M employee Spencer Silver accidentally developed a glue that was so weak it would barely hold two pieces of paper together? However, his colleague Art Fry needed the glue. Fry sang with his church choir and marked the pages of his hymnal with small scraps of paper that often fell out. He used Silver's glue to hold the papers in place. Today we call this invention Post-it Notes.

| Application No. | Application Title | Issue Date |
| 20100083742 | Method for testing the operation of a pressure sensing unit of an injection system of an internal combustion engine In a method for testing the operation of a pressure sensing unit of an injection system of an internal combustion engine, the injection system has no high-pressure valve. An error is detected when a pressure gradient value falls below a pressure gradient limit while at ... | 04/08/2010 |
| 20100024777 | Method for the localization of a fault location within a fuel injection system In a method for localizing a fault location within a fuel injection system, when a critical fault is detected by the diagnostic function, a pulse or a series of pulses to the injectors is triggered by a control unit. By observing the voltage value and/or charge value at... | 02/04/2010 |
| 20090309455 | METHOD FOR DETERMINING A FUNCTIONAL STATE OF A PIEZOELECTRIC INJECTOR OF AN INTERNAL COMBUSTION ENGINE A check is made to determine whether the capacitance value measured at a specific point in time corresponds to a capacitance value of a calculated further capacitance profile or the measured capacitance value is within two tolerance ranges.... | 12/17/2009 |
| 20080215296 | Method for Recognizing a Sensor Type A first condition, which is met when a measuring signal (V_SENS) of a sensor exceeds a first threshold value (V_SW), is checked. A second condition, which is met when a gradient (GRD_V_SENS) of a measuring signal (V_SENS) is greater than a predefined second threshold (G... | 09/04/2008 |
| 20050199051 | Method for determining defective actuators in an internal combustion engine Defective actuators in an internal combustion engine with at least one cylinder are detected. A mean value, in particular the arithmetic mean value, determines a measurement variable of all the actuators of a given type present on the cylinders. The measurement variable... | 09/15/2005 |
