| 141 | Accelerometer with detection mass including two magnets | JP5681690 | 1990-03-09 | JPH02281524A | 1990-11-19 | REONAADO DABURIYU BEAA; DONARUDO EI DEYUUDA |
| PURPOSE: To correct automatically temperature properties of magnetic bias force and magnetic breaking force by using a pair of permanent magnets placed so as to face same polarity through a spacer as detector mass. CONSTITUTION: Detector mass 34, which moves on a path 24 in an accelerometer 10 according to acceleration, is composed of a pair of permanent magnets 36 facing same polarity through a spacer with permeability and smaller diameter than that of the permanent magnet 36. When determining acceleration, the detector mass 34 in this structure cancels out temperature properties of magnetic bias force and magnetic breaking force, so that the temperature properties are automatically corrected with a simple structure.

| PURPOSE: To automatically compensate the temperature effect of a magnetic field by providing a stopping means which is moved along a passage in accordance with the temperature and a switching means which is actuated by means of a magnetic detecting weight which is arranged in the passage when the detecting weight is moved to a second position. CONSTITUTION: A magnetic detecting weight 46 is magnetically pressed against a washer 44 and held at a first position in the passage 24 to a stop 30 until an acceleration input larger than a threshold acts on to a housing 12. When the acceleration input larger than the threshold acts on the housing 12, the weight 46 is moved to a second position in the passage 24. At the second position, the conductive surface 56 of the weight 46 is engaged with a contact 54 and, when the surface 56 is engaged with the contact 54, the contact 54 is electrically bridged by the weight 46. In addition, the movement of the stop 30 in the passage 24 in response to the temperature offsets the temperature effect of a magnetic field generated by the washer 44 and weight 46 and the threshold acting on the weight 46 is nearly constantly maintained over the operating temperature range of a sensor 10.

| 143 | Acceleration sensor | JP19291788 | 1988-08-03 | JPS6454361A | 1989-03-01 | HARUTOMUUTO ZAIRERU |
| PURPOSE: To conduct tests in a state where an acceleration sensor is incorporated without applying any external inertial force by making a spring element deflectable and a traveling contact closable regardless of external acceleration by means of an electromagnet device at the dead position of the acceleration sensor. CONSTITUTION: When an inertial force acts on the earthquake mass 21 of an acceleration sensor 10, a spring element 16 closes both contacts 28 and 30 against the force of a returning spring 25 after a prescribed limit acceleration value is exceeded. As a result, safety devices respectively connected to terminal pins 32 and 33 are started. In addition, the sensor 10 can be tested without applying any external inertial force before or after the sensor 10 is incorporated in an automobile. Namely, when a sufficiently large current flows to a coil 14, the line of magnetic force of the magnetic field generated by the current passes through a yoke 11, an oscillating armature 18, and a magnetic core 12. When the force of the magnetic field becomes stronger than that of the spring 25, the armature 18 is attracted to the core 12 until the contacts 28 and 30 are closed. Therefore, the function of the sensor 10 can be tested continuously. When the current to the coil 14 is cut off, the element 16 is returned to its initial position by the force of the spring 25. | ||||||
| 144 | METHOD AND SYSTEM FOR DETECTING RELAY ADHESION | US15958284 | 2018-04-20 | US20180315568A1 | 2018-11-01 | Fei ZHAO; Xing WU; DeQing CHEN |
| A method and a system for detecting an adhesion of a relay are disclosed. In a high voltage circuit, a voltage is measured across a load multiple times within a specified time period when a first relay and a second relay are open and a third relay is closed, where the second relay may be a main negative relay of the high voltage circuit. The second relay is declared to have an adhesion malfunction when a change in the value of the measured load voltage satisfies a specified condition. Using the change in the sampled load voltages external to the main negative relay, the adhesion malfunction of the main negative relay may be diagnosed, so that corrective action may be taken. The potential safety hazard caused by the adhesion malfunction of the main negative relay may be prevented, such as may occur in an electric vehicle high voltage circuit. | ||||||
