Assembly of integrated circuit packages, such as BGA packaged devices, using fluidic self-assembly. The lamp assembly includes a lamp casing having elastic tongues at both sides thereof and mounted with a lamp therein, and a transparent cover having locking depressions at both sides thereof and inserted into the lamp casing. A second control module independent of the first control module receives the wakeup request and generates the wakeup signal after the vehicle powers off based on the wakeup request. The transducer is configured to provide a surface plasmon-enhanced near-field radiation pattern proximate the output end in response to the light received by the waveguide. The cooler yet further comprises a lid including two wheel storage recesses, each being sized and dimensioned to receive and retain one of the coaxial wheel of the wheel assembly, and an axle storage recess sized and dimensioned to receive and retain the axle of the wheel assembly. A network camera integrates the video analytics system to reduce network traffic.
