Abstract: A manufacturing process of the combining of optical lens and senor chips includes the steps of: preparation of a wafer with a plurality of image sensor chips thereon, connection of a plurality of optical lens assemblies to the wafer, wherein each of the optical lens assemblies is associated with the image sensor chip respectively, and division of the wafer to have a plurality of image catch units.

Abstract: The present invention provides a method of making an image capture unit, which includes the steps of: providing an image sensor; attaching a plate on the image sensor; providing at least one cavity on the plate aligned with the image sensor; mounting lenses in the cavity of the plate, and attaching a cover on the plate to shield a margin region of each of the lenses.

Abstract: A system and method for identifying a mobile user cluster by call detail records (CDRs) is provided. The system and method identifies at least one mobile user cluster according to a plurality of CDRs generated by a plurality of mobile users during a first period and a second period of time. Each mobile user of the identified cluster generates at least one CDR at a same geographical location during the first period of time, and a mobile user sequence is formed between any two mobile users of the identified cluster. At least one CDR is generated between any two neighboring mobile users of the mobile user sequence during the second period of time. Examples for the mobile user cluster include cohabiting family members, familiar neighborhood, colleagues, schoolmates, etc.
