Publication number: 20240019904Abstract: An edge surface includes a first peripheral surface extending between a first major surface and an outer peripheral surface of a substrate. The first peripheral surface includes a first depth and a first width. In aspects, the first depth is from about 4 micrometers to about 12 micrometers, and the first width is from about 30 micrometers to about 50 micrometers. In aspects, the first depth is from about 14 micrometers to about 24 micrometers, and the first width is from about 40 micrometers to about 60 micrometers. In aspects, a ratio of the first depth to a substrate thickness is from about 0.2 to about 0.4, a ratio of the first width to the substrate thickness is from about 1 to about 1.55, and a ratio of the first width to the first depth is from about 2 to about 8.Type: ApplicationFiled: July 14, 2023Publication date: January 18, 2024Inventors: YU CHENG, FANG-YU HSU, WEIRONG JIANG, PETER JOSEPH LEZZI, SAMUEL ODEI OWUSU

Patent number: 11870296Abstract: An uninterruptible power system and an operation method thereof are provided. The uninterruptible power system comprises a DC-AC conversion circuit, a plurality of switches, a plurality of sensing units, a plurality of output ports and a control unit. Each output port is electrically coupled to an output terminal of the DC-AC conversion circuit sequentially through one of the sensing units and one of the switches. The control unit is configured to define members of at least one group from the output ports according to a system setting, and define which members of each group are non-critical output ports according to the system setting. The control unit is further configured to set, according to the system setting, at least one condition for all non-critical output ports in each group to simultaneously stop supplying power, and to accordingly control the operations of the corresponding switches.Type: GrantFiled: November 17, 2021Date of Patent: January 9, 2024Assignee: CYBER POWER SYSTEMS, INC.Inventors: Kai-Tsung Yang, Jui-Hung Chou, Fang-Yu Hsu, Shou-Ting Yeh

Publication number: 20190330096Abstract: A method for treating a mold includes grinding an outer metal surface of a mold body of the mold with a first material; lapping the outer metal surface after the grinding with a second material that is finer than the first material; and polishing the outer metal surface after the lapping to achieve an average surface roughness (Ra) less than or equal to about 0.15 ?m and a waviness height (Wa) less than or equal to about 100 nm. A mold for shaping glass-based material can include a mold body having an outer metal surface, wherein the outer metal surface has an average surface roughness (Ra) less than or equal to about 0.15 ?m and a waviness height (Wa) less than or equal to about 100 nm.Type: ApplicationFiled: July 9, 2019Publication date: October 31, 2019Inventors: Yi-Chun Chiang, Jill Marie Hall, Fang-Yu Hsu, Shen Li, Ljerka Ukrainczyk, Hong Chih Wang

Patent number: 10137821Abstract: A low-beam-color-temperature-variable headlight unit includes a case, a condenser lens, a high-color-temperature light emitting diode, a low-color-temperature light emitting diode, and a low-beam-color-temperature control unit. The high-color-temperature light emitting diode emits high-color-temperature light. The high-color-temperature light emitting diode provides illumination of a first illuminated area. The low-color-temperature light emitting diode provides illumination of a second illuminated area that overlaps the first illuminated area at least partly. The low-color-temperature light emitting diode emits low-color-temperature light having a lower color temperature than the high-color-temperature light. The low-beam-color-temperature control unit is capable of adjusting the color temperature of the low beam by adjusting the quantity of light emitted from the high-color-temperature light emitting diode and the quantity of light emitted from the low-color-temperature light emitting diode.Type: GrantFiled: March 13, 2018Date of Patent: November 27, 2018Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Takehiro Inoue, Yumi Kimura, Fang-yu Hsu
