Abstract: Package structures and methods for manufacturing the same are provided. The package structure includes a first bump structure formed over a first substrate. The first bump structure includes a first pillar layer formed over the first substrate and a first barrier layer formed over the first pillar layer. In addition, the first barrier layer has a first protruding portion laterally extending outside a first edge of the first pillar layer. The package structure further includes a second bump structure bonded to the first bump structure through a solder joint. In addition, the second bump structure includes a second pillar layer formed over a second substrate and a second barrier layer formed over the second pillar layer. The first protruding portion of the first barrier layer is spaced apart from the solder joint.

Abstract: A cleaning system and a cleaning method are provided. The cleaning system includes a main body, an air suctioning device, a light source, an optical sensor, a memory and a processing unit. The air suctioning device includes an air flow passage and a fan-motor assembly that is disposed in the air flow passage and generates a suction force to suction outside air through the air flow passage. The light source emit light to the air flow passage. The optical sensor captures a plurality of successive image frames from the air flow passage. The processing unit is configured to: obtain first and second image frames from the successive image frames; compare the first image frame with the second image frame to identify dust particles; obtain a particle feature of the dust particles; and determine a current cleanness condition according to the particle feature.

Abstract: A vehicle side obstacle detecting and warning method is applied on a vehicle. The vehicle side obstacle detecting and warning method includes providing a measuring step for measuring a dataset of the vehicle. The vehicle side obstacle detecting and warning method includes providing a detector installing step for positioning a plurality of detectors between the front wheel and the rear wheel according to the maximum inner wheel difference area. The vehicle side obstacle detecting and warning method includes providing a detected area adjusting step for adjusting a detecting distance or a positioning angle of at least one of the detectors to form a detected area. The vehicle side obstacle detecting and warning method includes providing a detecting and warning step for sending a warning message by a warning module disposed at the vehicle when an obstacle is detected by any one of the detectors within the detected area.

Abstract: A hostless automobile reverse radar warning system installed to an automobile includes a reverse signal light power module for supplying an electric power required by the system, a plurality of distance sensing modules installed to an external periphery of the automobile for performing a distance detection to detect external environment conditions of the automobile, producing a distance detection result, and generating a warning signal based on the distance detection result, and a warning module for receiving the warning signal and producing a sound to alert a driver based on the warning signal.
