Patent number: 11950902Abstract: The present invention provides a micro biosensor for reducing a measurement interference when measuring a target analyte in the biofluid, including: a substrate; a first working electrode configured on the surface, and including a first sensing section; a second working electrode configured on the surface, and including a second sensing section which is configured adjacent to at least one side of the first sensing section; and a chemical reagent covered on at least a portion of the first sensing section for reacting with the target analyte to produce a resultant. When the first working electrode is driven by a first working voltage, the first sensing section measures a physiological signal with respect to the target analyte. When the second working electrode is driven by a second working voltage, the second conductive material can directly consume the interferant so as to continuously reduce the measurement inference of the physiological signal.Type: GrantFiled: July 31, 2020Date of Patent: April 9, 2024Assignee: Bionime CorporationInventors: Chun-Mu Huang, Chieh-Hsing Chen, Heng-Chia Chang, Chi-Hao Chen, Pi-Hsuan Chen

Patent number: 11946591Abstract: A foldable stand has a base, a riser, and a switching mechanism. The riser is located on the base. The switching mechanism connects the base and the riser such that the riser selectively pivots relative to the base from an upright position to a folded position. The switching mechanism has a locked status and a released status. In the locked status, the switching mechanism prevents the riser from pivoting relative to the base. In the released status, the switching mechanism allows the riser to pivot relative to the base from an upright position to a folded position. The switching mechanism is configured to be switched from the locked status to the released status by rotation of the riser around a centerline of the riser.Type: GrantFiled: February 23, 2022Date of Patent: April 2, 2024Assignee: Reliance International Corp.Inventors: Chi-Chia Huang, Cheng-Lin Ho, Eric Langenhahn

Patent number: 10937400Abstract: A cable-driven beater mechanism for a percussion instrument has a base, a transmission shaft pivotally mounted on the base, a beater connected to the transmission shaft, a cable transmission assembly, a restoring spring and a cable. An elongated guiding slot is formed in the standing plate. The cable transmission assembly is pivotally mounted on the base and protrudes into the guiding slot. The cable and the transmission shaft are connected via the cable transmission assembly. Pulling force from a player is transferred via the cable to pivot the transmission shaft and the beater. The restoring spring returns the transmission shaft and the beater to an original position. The cable moves along a straight line during operation to reduce rubbing and repeated bending of the cable, which prolongs service life of the cable, reduces noise during operation, and allows the beater to respond more swiftly to the pulling force.Type: GrantFiled: March 31, 2020Date of Patent: March 2, 2021Assignee: RELIANCE INTERNATIONAL CORP.Inventors: Pei-Chi Chu, Cheng-Lin Ho, Wei-Ting Chen, Chi-Chia Huang
