    Abstract: A sensing method and system for Fresnel lenses are disclosed, the system including a first Fresnel lens unit for sensing the signal of a target object crossing a first boundary of a sensing area, a second Fresnel lens unit for sensing the signal of a target object crossing a second boundary of the sensing area, a third Fresnel lens unit for sensing the signal of a target object crossing a third boundary of the sensing area, and a sensing unit for receiving and processing the sensed signals of the Fresnel lens units. The first and second Fresnel lens units are arranged on two sides of the third Fresnel lens unit. Furthermore, it is possible to add more Fresnel lens units above, below or around the Fresnel lens units. By monitoring the boundaries of the sensing area, the sensing method and system for the Fresnel lenses improve the insufficiency of the sensing area, reduce cost and save power consumption.

    Abstract: An integrated optical auto focus and zooming system is provided, which includes a first optical lens, a first hollow casing, a second hollow casing, a plurality of piezoelectric elements. The first optical lens is placed in the first hollow casing, the first hollow casing and the second hollow casing are screwed with each other, and the plurality of piezoelectric elements are attached either on the first hollow casing or the second hollow casing. Upon the excitation of mechanical vibrations by the plurality of piezoelectric elements, a traveling wave is generated on the attached casing, so as to drive the other casing to rotate and then to move axially. Additional lens groups and casings can be added in the same way so to achieve multiple relative motions between lens groups and image sensor, and thus achieving the objectives of focusing and zooming. The present invention integrates the motor into the lens and hence eliminates the transmission mechanism, leading to simple structure, high efficiency, and multiple advantages in size, cost, and efficiency, etc., and thus can be very useful.

    Abstract: A method for assembling a semiconductor package includes a rapid cooling step after post mold curing of an encapsulation material. The rapid cooling step includes blowing chilled, compressed air over the package for about two minutes. The rapid cooling step does not require any clamping pressure be simultaneously applied to the package. The rapid cooling step reduces a temperature of the encapsulation material from a curing temperature to the cooled temperature within a maximum period of less than five minutes. By using rapid cooling, as opposed to cooling the package under a clamping pressure with ambient air, package warpage due to CTE mismatches is prevented.
