Abstract: A smart cooling fan system is disclosed, and comprises a first temperature sensor, a second temperature sensor, a first cooling fan connected to a main processor of an electronic device, a second cooling fan disposed in a housing case of the electronic device, and a microcontroller. The microcontroller is configured to, based on immediate fan rotation speed, find out a first volumetric flow rate and a second volumetric flow rate by looking up a CFM-RPM lookup table (LUT), a first PWM LUT and a second PWM LUT, the microcontroller controls the first cooling fan to produce a first airflow having the first volumetric flow rate, and also controls the second cooling fan to produce a second airflow having the second volumetric flow rate. As a result, the operating temperature of the main processor and an ambient temperature of the housing case are therefore immediately reduced.

Abstract: In laser welding of metallic workpieces, the energetic beam is moved over the workpiece surface to form a pool of molten weld metal that quickly solidifies behind the advance of the laser into a weld nugget. The laser beam produces a keyhole of plasma-containing vapor within the molten pool. Weld nugget porosity, due to entrapment of the vapor, is minimized by continually sensing radiation from the molten metal pool to determine pool depth and width and then controlling laser power and speed to continually produce a weld metal pool wide enough for the liquid to fully expel the vapor and solidify into a pore free nugget.

Abstract: A modular body for a vehicle includes a first module having a first B-pillar interface and a second module having a second B-pillar interface. The first and second modules are joined at the first and second B-pillar interfaces defining a B-pillar thereat.

Abstract: A window washer control system and method administers fluid intermittently to a window based on an intermittent setting. A washer switch includes a plurality of frequency settings for varying a time interval between fluid administering events. The fluid level in a washer fluid reservoir is monitored to ensure a predetermined level. If the fluid level is below a predetermined level, control prevents intermittent washer administration and allows only manual activation.
