Abstract: A system includes a plurality of sensors configured to sense an opening/closing of a door, fastening/unfastening of a seat safety belt, and change in a vehicle height; a first processor configured to determine the number of all occupants in the vehicle by the opening/closing of the door, the fastening/unfastening of the seat safety belt, and the change in the vehicle height sensed by the plurality of sensors and preliminarily determine an internal circulation ratio of the air conditioning system according to the determined number of all occupants in the vehicle; a second processor configured to adjust the internal circulation ratio which is preliminarily determined by the first processor according to at least one of a sound intensity and a sound duration time in the vehicle; and a controller configured to control the air conditioning system according to the adjusted internal circulation ratio.

Abstract: Disclosed are a computer-implemented method, a system and a computer program product for feature processing. In the computer-implemented method for feature processing, two input features selected from multiple features of each sample in a sample set are projected to one resulting feature by one or more processing units based on a specified curve. The sample set is updated by replacing the two input features with the one resulting feature for each sample in the sample set by one or more processing units. The projecting and the updating for the sample set are repeated by one or more processing units until the number of features of each sample in the sample set reaches a predetermined criterion.

Abstract: A waterproof connector (10) includes an annular rubber ring (30) and a housing (20) on which the rubber ring (30) is to be mounted. A trapezoidal rotation stopping rib (34 having two engaging surfaces is provided on a side edge of the rubber ring (30), whereas an accommodation groove (26) into which the rotation stopping rib is to be accommodated is provided in the housing (20). The accommodation groove (26) has a bottom surface (21A). Two facing engaged surfaces (42) are on both sides of the bottom surface (21A) and are configured to press the rotation stopping rib to the bottom surface (21A) by being engaged with the engaging surfaces of the rotation stopping rib.

Abstract: A waterproof connector (10) disclosed by this specification includes an annular rubber ring (30) and a housing (20) on which the rubber ring (30) is to be mounted. A rotation stopping rib (trapezoidal rib (34)) having a pair of engaging surfaces is provided on a side edge of the rubber ring (30), whereas an accommodation groove (26) into which the rotation stopping rib is to be accommodated is provided in the housing (20). The accommodation groove (26) is composed of a bottom surface (21A) and a pair of engaged surfaces (facing surfaces (42)) provided on both sides of the bottom surface (21A) and configured to press the rotation stopping rib to the bottom surface (21A) by being engaged with the engaging surfaces of the rotation stopping rib.

Abstract: A method for updating firmware of a rackmount server system is disclosed herein and is suited to update a firmware of an update-needed chip module by a control chip module. The method includes the following steps of: sending a plurality of packets constituting a renewed firmware to the update-needed chip module by the control chip module; sending a command of verifying the plurality of packets to the update-needed chip module by the control chip module; acquiring a plurality of verification messages, corresponding to the plurality of packets, from the update-needed chip module by the control chip module; and determining whether all of the plurality of verification messages corresponding to the plurality of packets are correct or not by the control chip module, thereby making sure whether the plurality of packets received by the update-needed chip module are incorrect or not.
