Abstract: A stator winding of a sheet-metal stator for an electric motor. A stator lamination stack of the stator is equipped with an insulating end plate. Stator teeth protruding in the radial direction are wound with a winding wire. After a specified number of stator teeth, the winding wire is guided away from the stator lamination stack and then back to the stator lamination stack, thereby forming an at least U-shaped loop. The loop is then used to contact a motor electronics unit of the electric motor.

Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for using electrical button matrix scanning techniques to detect remote control buttons pressed by users. An example embodiment operates by detecting, using an electrical matrix scanning technique, an actuated electrical switch corresponding to a remote control action for a media device. The actuated electrical switch includes a first actuated electrode coupled to a first actuated electrical line of an electrical matrix, a second actuated electrode coupled to a second actuated electrical line of the electrical matrix, and a third actuated electrode coupled to a third actuated electrical line of the electrical matrix. In response to detecting the actuated electrical switch, the example embodiment operates by triggering an execution of the remote control action corresponding to the actuated electrical switch.

Abstract: A cooling tower fan hub having a ring and a disc in which in which hollows and recesses are opened in the ring and/or in the disc in order to decrease fan natural frequencies and avoid excitation by the several kind of loads that affect a fan during operation. The number, size and shape of the hollows can be adjusted to tune the fan natural frequencies around the original value.

Abstract: Described herein are several examples of an apparatus that features receptacles configured to accept interchangeable buttons. Each of the interchangeable buttons has a receptacle interface on a first side, which allows them to electrically connect to and communicate with the aforementioned apparatus, and a unique user-perceivable label on a second side. Electronic elements embedded in each interchangeable button, or alternatively located on its first side, correspond to a unique user-perceivable label. Based on these electronic elements, the apparatus recognizes each button individually, and identifies their user-perceivable label. As a result, the interchangeable buttons may be re-positioned on the apparatus and maintain their intended functionality according to their user-perceivable label. In addition, new interchangeable buttons with different user-perceivable labels and new functionality, according to their labels, can be introduced to the apparatus.
