Publication number: 20240142428Abstract: A water quality detection device including a detection tank, a sensor, the cleaner and a processor is provided. The sensor is disposed on the detection tank and is configured to sense a to-be-detected liquid within the detection tank. The cleaner is configured to clean the sensor. The processor is electrically connected to the sensor and the cleaner and is configured to: execute an initialization procedure, which includes driving the sensor to sense the to-be-detected liquid to obtain a number of initial sensing values and calculating a threshold value according to the initial sensing values; drive the sensor to sense the to-be-detected liquid to obtain a sensing value of the to-be-detected liquid, and determine whether the sensing value of the to-be-detected liquid reaches the threshold value; drive the cleaner to operate when the sensing value of the to-be-detected liquid reaches the threshold value.Type: ApplicationFiled: February 17, 2023Publication date: May 2, 2024Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Tsung-Yu TSAI, Hung-Sheng LIN, Cheng-Da KO, Chun-Te CHUANG

Patent number: 11769625Abstract: A transformer apparatus reducing magnetic field interference includes an iron core, a first side coil unit, a second side coil unit, a first current transmission line, a second current transmission line and a third current transmission line. Both the first side coil unit and the second side coil unit are wound around the iron core. The first side coil unit is connected to the first current transmission line and the second current transmission line. The second current transmission line is connected to the third current transmission line. The first current transmission line includes a first current conduction segment and a first insulation layer. The first insulation layer coats the first current conduction segment. The third current transmission line includes a second current conduction segment and a second insulation layer. The second insulation layer coats the second current conduction segment. The second insulation layer touches the first insulation layer.Type: GrantFiled: December 8, 2020Date of Patent: September 26, 2023Assignee: P-DUKE TECHNOLOGY CO., LTD.Inventors: Lien-Hsing Chen, Cheng-Te Tsai, Sheng-Ken Huang

Patent number: 9614363Abstract: An under voltage protection device includes a voltage detector and a starting unit. The voltage detector includes a diode, a variable resistor, a transistor and a fixed-resistance resistor. The starting unit includes a second transistor. When a voltage of the external voltage source is smaller than a voltage of the diode, a voltage between an emitter node and an collector node of the first transistor is smaller than a threshold voltage present between a gate node of and a source node of the second transistor such that the starting unit is turned off. When the voltage of the external voltage source is larger than the voltage of the diode, the voltage between the emitter node and the collector node is larger than the threshold voltage present between the gate node and the source node such that the starting unit is turned on.Type: GrantFiled: September 25, 2015Date of Patent: April 4, 2017Assignee: Power Mate Technology Co., Ltd.Inventors: Lien-Hsing Chen, Cheng-Te Tsai, Sheng-Ken Huang
