Title: Fuel level sensor having dual fluorescent plastic optical fiber
Inventor: CHAN ERIC Y
IPC: G01F23/292
Filed: 2018-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a fuel level sensor having a dual fluorescent plastic optical fiber.SOLUTION: An aircraft fuel level optical sensor is provided that uses one side-emitting plastic optical fiber (SPOF) and two fluorescent plastic optical fibers (FPOFs) to detect the airplane fuel level without using any electrically conductive component or element placed inside the fuel tank. This dual-FPOF sensor is capable of achieving high resolution and high accuracy with a one-time calibration in the actual airplane's fuel tank environment. One embodiment of the dual-FPOF sensor uses one SPOF and two FPOFs to detect fuel level change based on the optical signal output from the two FPOFs. The sensor design uses large-diameter (core and cladding), lightweight, low-cost and high-durability plastic optical fiber, which is very desirable for airplane installation.SELECTED DRAWING: Figure 1

Title: Ac non-consumable electrode arc-welding control method
Inventor: TAKADA KENTO
IPC: B23K9/00
Filed: 2018-02-22
Abstract: To maintain an average current value to a specified value even if a weld cable is long in AC non-consumable electrode arc-welding.SOLUTION: In AC non-consumable electrode arc-welding control method for welding by conduction of AC welding current Iw, an average value of an absolute value of the welding current Iw is detected, and amplitude control for changing an amplitude of the welding current Iw is performed so that the average value becomes equal to a predetermined average current set value. Further, said amplitude control is performed only when an absolute value of a difference between the average value and the average current set value is a reference value or higher. In addition, said amplitude control is performed only during a prescribed period from an arc start. Consequently, an inductance value becomes large since a weld cable is long, and the average current value is maintained to a prescribed value even if a welding current waveform is changed, and therefore, a weld penetration depth can be stabilized.SELECTED DRAWING: Figure 2

Title: Resident absence/presence management system and absence/presence determination terminal and computer program used therein
Inventor: OKADA KOJI
IPC: G08B25/04
Filed: 2018-03-05
Abstract: To provide a resident absence/presence management system that determines whether a resident is present or absent in an entire residence including a resident area outside of a dynamic body detection range without imposing an operational burden on the resident and allows a third party to use a determination result.SOLUTION: A system reads an input state of a dynamic body detection signal at a dynamic detection unit 2 within a predetermined detection active period triggered by reception of a door closing signal by an entrance door 202. It completes a cycle of absence/presence determination processing as the detection active period ends and moves to a standby state of next absence/presence determination processing to be started triggered by new reception of the door closing signal. If a new determination result is obtained, it updates the determination result, whereas if a new determination result is not obtained, it holds storage contents of the determination result regardless of the dynamic body detection state by the dynamic body detection unit 2. As a result, when it is determined that a resident is absent, it outputs a determination result of absence regardless of whether a person P2 is within a resident area 204 outside of a detection area DA of the dynamic body detection unit 2.SELECTED DRAWING: Figure 1A
