Abstract: A method to set up the parameters of solder paste screen printer while in a new product introduction (NPI). The method includes establishing a solder-printing database of a predetermined product and a database of different specifications of products, and training a first prediction model by reference to a solder paste screen printer (SPSP) and a solder paste inspection (SPI) based on the solder-printing database. A second prediction model is trained by reference to the SPI based on the database of different products. The method further includes predicting parameters for products with different specifications under multiple sets of printing parameters based on the first and second prediction models. An objective function based on the predicted measurements is established, and a specification of a product and a printing expectation parameters are input to the objective function for outputting many sets of printing-suggestion parameters of the new product.

Abstract: A seat assembly is provided having a side shield having a leading edge. The side shield adapted to cover at least a portion of the seat cushion of the seat assembly. The assembly further includes a seat cushion, the side shield positioned adjacent to the seat cushion, the seat cushion having an elongated trench adapted to receive the leading edge of the side shield so as to prevent the formation of a gap between the shield and the cushion portion thereby providing an aesthetically appealing appearance to the user. The seat cushion includes a side surface positioned adjacent to the side shield. The trench is further defined as a generally horizontal momentary discontinuous surface extending into the side surface of the seat cushion, the leading edge of the side shield resting within the trench. The side shield extends around the seat cushion to a front portion of the seat cushion and the trench adapted to accept the leading edge of the side shield at the front portion of the seat cushion.

Abstract: A multi-function touch pen for a portable electronic device includes a pen body and an audio output module. The pen body includes a touching input terminal, located at a first end of the pen body for inputting information to the portable electronic device, and an audio input unit located adjacent to the touch input terminal for inputting audio signals to the portable electronic device. The audio output module is located at a second end of the pen body for outputting audio signals generated from the portable electronic device.

Abstract: A seat back frame assembly and seat assembly are provided. The seat back frame assembly includes a pair of side members spaced apart from each other, a top member spaced apart from a bottom member, each of the top and bottom members interconnecting each of the pair of side members so as to define a peripheral edge, the peripheral edge enclosing a back space. An interference member is disposed within the back space and spaced apart from an inner surface of one of the pair of side members. The interference member disposed above a midpoint of the one of the pair of side members and includes a sliding surface angled obtusely with respect to the back space so as to direct an occupant forward of the back space and away from the side member when experiencing a side load.
