Abstract: An automotive battery module with numerous battery cells and a series-based cooling fin arrangement placed in thermal communication with at least two of the battery cells. Heat generated within the battery cells by, among other things, electric current that can be used to provide motive power for the automobile, may be removed by the cooling fin that includes different portions tailored to remove relatively lesser or greater amounts of heat, depending on a potential temperature difference among the cells.

In one form, the multiple heat transfer paths may include a relatively laminar portion and a relatively turbulent portion, where in one form the increased turbulence may be obtained through numerous turbulators.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
