Patent number: 8390087Abstract: The present invention discloses an image sensor package structure with a large air cavity. The image sensor package structure includes a substrate, a chip, a cover and a package material. The chip is combined with the substrate. A plastic sheet of the cover is adhered to the chip and a transparent lid of the cover is combined with the plastic sheet to provide a covering over a sensitization area of the chip so as to form an air cavity. The package material is arranged on the substrate and encapsulated around the chip and the cover. The plastic sheet having a predetermined thickness can increase the distance between the transparent lid and the chip to enlarge the air cavity. Thus, the image-sensing effect of the image sensor package structure can be improved and the ghost image problem resulting from multi-refraction and multi-reflection of light can be minimized.Type: GrantFiled: January 7, 2010Date of Patent: March 5, 2013Assignee: Kingpak Technology Inc.Inventors: Hsiu-Wen Tu, Ren-Long Kuo, Young-Houng Shiao, Tsao-Pin Chen, Mon-Nam Ho, Chih-Cheng Hsu, Chin-Fu Lin, Chung-Hsien Hsin

Publication number: 20120181860Abstract: A device and method for operating automotive battery system relays and related switches. By creating a dual bipolar magnetic field adjacent the contactor portion of a switching mechanism in the relay, the magnetic field used to promote arc extinguishing is shifted, which in turn reduces the Lorentz force that forms as a byproduct of the field. Such a configuration has the potential for simultaneously maintaining arc-extinguishing capability and improving short-circuit withstanding capability while reducing the tendency of the Lorentz forces to interfere with the operation of a solenoid or other switch-activating mechanisms. Such devices and methods may be used in conjunction with hybrid-powered and electric-powered vehicles.Type: ApplicationFiled: March 31, 2011Publication date: July 19, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Chih-Cheng Hsu, Andrew J.

Publication number: 20120181953Abstract: A device and method for operating automotive battery system relays and related switches. By aligning a magnetic field with a direction of current flow in a contact plate disposed between magnets that are producing the field, a generated Lorentz force can be used to promote arc extinguishing during a relay opening sequence, while simultaneously reducing the tendency of the Lorentz forces to interfere with the operation of a solenoid or other switch-activating mechanisms. By using a rotary-based mechanism to establish contact between a contact plate and current-carrying terminals, the likelihood of inadvertent opening of the relay is reduced. Such devices and methods may be used in conjunction with hybrid-powered and electric-powered vehicles.Type: ApplicationFiled: May 23, 2011Publication date: July 19, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Chih-Cheng Hsu, Andrew J.

Publication number: 20120061998Abstract: The substitution of aluminum alloy roof panels for the low carbon steel roof panels most commonly used in motor vehicles is an attractive option for vehicle mass reduction. Often, however, the remainder of the vehicle body structure continues to be fabricated of steel. The combination of the aluminum alloy roof attached to the steel body may create compressive stresses in the aluminum roof when the body is subjected to elevated temperatures such as those required to cure or bake the paint applied to the body. These stresses may lead to unacceptable appearance features in the visible segment of the roof. By modifying the roof stamping to introduce a tabbed flange for attachment to the body and/or modifying the generally-vertical wall joining the flange to the roof interior, the stresses may be minimized and relocated to segments of the roof not normally visible.Type: ApplicationFiled: September 14, 2010Publication date: March 15, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: John E. Carsley, Chih-Cheng Hsu, Stewart Edmison

Publication number: 20110024610Abstract: The present invention discloses an image sensor package structure. The image sensor package structure includes a substrate, a chip, a transparent lid, a first casing and a package material. The transparent lid covers a sensitization area of the chip and it also adheres to the chip which is deposed on the substrate. The first casing, which adheres to the transparent lid, forms an opening so that light can pass through the opening and the transparent lid to enter into the sensitization area. The package material covers around the chip and the transparent lid and fills between the substrate and the first casing. Because of the arrangement of adhesive layers placed between the first casing and the transparent lid and between the transparent lid and the chip, the blockage area from moisture is elongated. Therefore, the reliability of the image sensor package structure can be enhanced.Type: ApplicationFiled: October 15, 2009Publication date: February 3, 2011Applicant: Kingpak Technology Inc.Inventors: Hsiu-Wen Tu, Ren-Long Kuo, Young-Houng Shiao, Tsao-Pin Chen, Mon-Nan Ho, Chih-Cheng Hsu, Chin-Fu Lin, Chung-Hsien Hsin
