Abstract: Embodiments of systems and methods of additive manufacturing are disclosed. In one embodiment, a metal deposition device (MDD) is configured to deposit a metal material during an additive manufacturing process. A controller is operatively coupled to the MDD and is configured to command the MDD to deposit the metal material on a base to form a contour of a part. The controller is configured to command the MDD to deposit the metal material on the base to form an infill pattern within a region outlined by the contour. The infill pattern is a wave shape having a wavelength. The controller is configured to command the metal deposition device to fuse the infill pattern to the metal contour at crossover points, where the infill pattern meets the contour, by applying energy at the crossover points and reducing a deposition rate of the metal material at the crossover points to prevent distorting the contour.

For example, one system for reducing emissions from engines comprises a heating controller coupled to an energy storage device (ESD). The heating controller is configured to control a heating element to heat one or more components of an after-treatment system using energy from the ESD under a first condition and to control the heating element to stop heating the one or more components of the after-treatment system when a second condition is satisfied. Additionally, another system for reducing emissions from engines comprises a controller detecting a decrease in a demanded torque from an engine and an ISG. The controller is then configured to operate a clutch to disengage the engine from the ISG, if after removing fuel from the engine, the sensed speed of the engine is above a threshold.

Abstract: A motorized drapery system having an elongated rotating drive element that has a non-circular cross-sectional shape such as square, rectangular, trapezoidal, cross shaped or any other non-circular shape that is twisted. In one arrangement the drive element is twisted in one direction along its entire length. In another arrangement the drive element is twisted in one direction in a first section and twisted in an opposite direction in a second section thereby providing a center opening/center closing drapery. A plurality of rings are positioned around the drive element including at least one driver ring that includes a feature that connects to the drive element and is configured to facilitate movement along the drive element, and a plurality of idler rings that are configured to slide along the drive element. A curtain is connected to the rings and opens and closes as the rings move along the drive element.

Abstract: A valance system for a window covering that can be folded and placed within the same shipping box as a wall bracket, top bracket and track sections. The valance extends a length between opposing ends and includes a clip feature that extends out from its rearward side. The clip feature is generally C-shaped or U-shaped when viewed from the side and includes a plurality of friction members in its exterior surface. The valance is covered with a covering material. An end cap having a hinge area that facilitates bending of the end cap is connected to the ends of the valance by connection of a tongue of the end cap to a slot of the valance. The clip feature is sized and shaped to frictionally fit within and be installed within a socket of a top bracket without any tools.

Abstract: Embodiments of systems and methods related to the automatic adjustment of auto-darkening filter device parameters in response to settings of a welding system are disclosed. One embodiment includes a head-mounted device having a wireless receiver, an auto-darkening device, and a selection device. The wireless receiver is configured to receive wirelessly transmitted communication signals from an arc welding system which represent a present welding current setting and a present welding mode setting of the arc welding system. The selection device is configured to automatically select a shade and a sensitivity of the auto-darkening device in response to the present welding current setting and the present welding mode setting. The auto-darkening device is configured to sense the presence of an arc, transition from an un-darkened state to a darkened state in response to the arc, and transition from the darkened state to the un-darkened state when the arc is no longer present.

Abstract: A method of operating a motorized window covering is presented wherein in response to a standard movement command power is supplied to a motor in a continuous or generally continuous manner thereby moving the shade material from a start position to an end position in a generally continuous manner. However, in doing so, the motor rotates at a fast rate thereby causing elevated noise levels. In response to an automated movement command, power is supplied to the motor by cycling power to the motor between a powered state and an unpowered state thereby moving the shade material from a start position to an end position in an incremental manner. While moving the shade material in this incremental manner is slower, it is substantially quieter. The preferred mode of operation is selected based on whether the movement command is a standard movement command or an automated movement command.
