Patent number: 9086227Abstract: A light collection system including a light concentrating device and a reflective curving-surface device is provided. The light concentrating device receives at least a portion of an incident light and forwardly emits the portion of the incident light after concentrating and passing it through a first focal region, so as to obtain a first-stage output light. The reflective curving-surface device has an entrance aperture for receiving the first-stage output light. The reflective curving-surface device includes a reflective inner curving surface, and at least a portion of the reflective inner curving surface has a second focal region. The first focal region and the second focal region are confocal or approximately confocal within a range. As a result, at least a portion of the first-stage output light is confocally converted into a forwardly emitted second-stage output light.Type: GrantFiled: January 22, 2009Date of Patent: July 21, 2015Assignee: Industrial Technology Research InstituteInventors: Liang-De Wang, Yuan-Xiang Zou, Li-Chi Pan, Pin Chang

Patent number: 8763457Abstract: A sensing device can be provided with sealed and open-type chambers in various conditions for accommodating different types of sensing structural components by stacking multiple substrates, wherein the condition of a sealed chamber depends on condition taken in substrate bonding process. Owing to sealing a channel of the sealed chamber by the substrate, superior sealing performance is achieved as compared to those adopting solder or sealing material, and thus the condition of the sealed chamber can be finely controlled.Type: GrantFiled: June 6, 2011Date of Patent: July 1, 2014Assignee: Industrial Technology Research InstituteInventors: Lung-Tai Chen, Yu-Wen Hsu, Tzong-Che Ho, Li-Chi Pan
