Abstract: This disclosure provides methods, components, devices and systems for coordination for smooth beamforming. Some aspects more specifically relate to techniques to reduce phase misalignment and delay spread to beamformed messages such that a receiving device may apply channel smoothing filtering to the received beamformed message. In some examples, the transmitting device may ensure that the delay spread of the steered channel for a beamformed message is roughly matching the delay spread of an open-loop channel. The transmitting device may signal for the receiving device to perform channel smoothing filtering to a received beamformed message, for example, because the transmitting device applies techniques to reduce the phase misalignment and delay spread to the beamformed message. In some examples, based on the indication, the receiving device may apply channel smoothing filtering to a beamformed transmission received from the transmitting device.

Abstract: A technique for wireless communication of a punctured null data packet with a long training field sequence is disclosed. The long training field (LTF) sequence is generated for the null data packet (NDP) for transmission over a channel having a bandwidth that is an integer multiple of 80 MHz. The LTF sequence is modulated onto a plurality of tones of the channel excluding tones within a punctured subchannel of a plurality of subchannels of the channel. The modulation may be based on a size and location of the punctured subchannel and a symbol duration associated with transmitting the LTF sequence. The NDP is transmitted including the LTF sequence to a second wireless communication device via the channel. A partial bandwidth feedback may be received in response to the LTF in the punctured NDP.

Abstract: An image capturing apparatus and an image zooming method thereof are provided. In the method, a wide image and a tele image are captured by utilizing a wide-angle lens and a telephoto lens respectively. An object of interest in the wide image or the tele image is recognized. Then, a zoom factor is received to zoom the wide image or the tele image, and a capture range of a window of interest (WOI) for capturing each of the wide image and the tele image is adjusted in a zooming process such that a center of the wide image captured by the window of interest moves toward the object of interest. Also, when the zoom factor reaches a magnification of the telephoto lens, the object of interest is as the same position in the wide image and the tele image captured from the window of interest.

Abstract: A device and a method for automatic swing control are disclosed. The device and method are used for the automatic swing control of an overhang. The device for automatic swing control comprises an actuator and a movable block. The movable block comprises a hanger and an angle sensing device.
