Filed: 1987-05-02
Abstract: PURPOSE:To discover a sudden illness at an early stage, by providing a detection circuit generating extension and contraction corresponding to acceleration or displacement and continuously performing measurement while sampling said change and a means for emitting an alarm when the change does not extend over a long period of time. CONSTITUTION:A sensor 1 is constituted of a membrane having elasticity and the extension and contraction of the membrane is changed to a change in electric resistance. The periphery of the sensor 1 is supported by a support 2 and a wt. 3 is mounted to the center of the sensor 1 and the electric resistor of one side is guided to a detection circuit 5 through a connection 7. When the surface of the sensor 1 forms a horizontal surface toward the center of gravity, all of the sides of the sensor 1 are stretched by the force of the wt. 3 and, when the surface of the sensor 1 displaces with respect to the direction of the gravity of the earth, change is generated in the resistance of the sensor 1. When this resistance value is inputted to the detection circuit 5 and change is continuously observed, it is cleared how a person to be monitored moves with respect to the center of gravity and, when there is no change in resistance over a long time, a transmitter 6 is operated to emit an alarm. Therefore, a person becoming immobile by an accident such as cerebral lesion can be discovered.

Title: Environment-diagnosing device for electrical equipment
Inventor: ITO HITOSHI
IPC: G01N17/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent an erroneous diagnosis due to the adhesion of dust and the contact of a finger and to improve reliability by covering a conductive material for detection with a coating material having water absorption property and gas transmission property. SOLUTION: A conductive material 12 for detection where a wiring pattern 12 such as copper for constituting the main part of an electrical equipment to be diagnosed is provided together is covered with a silicon coating material 14 being provided on a test chip 10. When the conductive material 12 is disconnected due to oxidation and corrosion or the electrical resistance of the conductive material 12 exceeds a specific value, it is detected by a switching circuit 6 and a corresponding display device 7 lights up. Since the conductive material 12 is covered with the coating material 14 with a water absorption property and a gas transmission property, no dust is adhered to the conductive material 12 and the influence due to the contact of a finger is eliminated, thus preventing an erroneous diagnosis and improving reliability.  Also, since the coating material 14 can transmit gas constituents and water, the interface between the conductive material 12 and the coating material 14 becomes an acceleration environment diagnosis state, thus predicting the failure of an electrical equipment in advance.
