Title: Volumetric pressure converter to be used in respirator device
Inventor: KENESU EICHI BOORU
IPC: A61M16/00
Filed: 1992-04-16
Abstract: PURPOSE: To provide a capacitive pressure transducer for use in a respirator system, which responds only to an inspiratory respiratory cycle. CONSTITUTION: Substrate members, a conductive diaphragm 14 and a spacer 17 are joined together into an integrated assembly, where the portion of the diaphragm 14 facing an opening 17a in the spacer 17 freely moves in the opening to one substrate member having a metal plate while the diaphragm 14 is prevented from moving away from the spacer 17 by the other substrate member. The opening in the spacer 17 forms a respiratory gas inlet together with the substrate member with the metal plate. The diaphragm 14 and the metal plate form a capacitor, the capacitance of which varies in response to the pressure differential between the gas inlet and the atmosphere to thereby cause the diaphragm 14 to freely move toward the metal plate in response to the negative pressure or suction induced in the interval of the in spiration of a patient.

Title: Laser alarm system
Inventor: UCHIDA MAKOTO
IPC: G01S17/06
Filed: 1989-04-18
Abstract: PURPOSE:To detect the position and track of an object in the vicinity of a light source by emitting a flat-plate-shaped laser light in tracking the object, by detecting a reflected light or a scattered light from the object and by measuring an angle of elevation of the object therefrom. CONSTITUTION:When an object 3 comes to a position A at a time t0, a laser element 1 of a laser alarm device tracks the object 3 in the direction of an angle phi1A. A laser element 2 tracks the object 3 in the direction of an angle phi2A. When the object 3 reflects or scatters a laser light of a laser light source, light-sensing units of the laser elements 1 and 2 sense the reflected or scattered laser light. Based on the laser light sensed by the laser elements 1 and 2, the laser alarm device measures a distance to and an angle of elevation of the object. By this measurement, positions, A, B and C of the object 3 at times t0, t1 and t2 can be detected. The track of the object 3 can be determined also from these positions A, B and C. If a time interval is set to be shorter, the track of the object 3 can be determined accurately.
