Abstract: A PIM shield is provided that extends laterally and longitudinally behind dual-antennas that are adjacently mounted side-by-side. The PIM shield can have a frequency selective surface that block or reflect signal at low and mid-band and that allows signal at high band to propagate therethrough. The PIM shield can be provided as two separate bodies, one behind a first one of the dual antennas and one behind a second one of the dual antennas.

Abstract: A method for controlling a movable object includes determining, based on current location information of an obstacle, whether the obstacle is located within a certain distance range from the movable object, and in response to determining that the obstacle is located within the certain distance range from the movable object: determining, based on the current location information of the obstacle, whether the obstacle meets a first distance criterion or a second distance criterion, to obtain a determination result, and performing a first adjustment or a second adjustment on one or more movement characteristics of the movable object based on the determination result. The first adjustment is different from the second adjustment. One of the first adjustment and the second adjustment includes changing a movement direction of the movable object from a first direction to a second direction. The first direction is opposite to the second direction.

Abstract: A method for controlling a movable object includes obtaining current location information of an obstacle while the movable object tracks a target, determining whether the obstacle is located in a reactive region relative to the movable object based on the current location information of the obstacle. In response to determining that the obstacle is located in the reactive region, the method further includes determining, based on the current location information of the obstacle, whether the obstacle is located in a first sub-region or a second sub-region of the reactive region, where an area of the second sub-region is smaller than an area of the first sub-region; in response to determining that the obstacle is located in the first sub-region, reducing an acceleration of the movable object; and in response to determining that the obstacle is located in the second sub-region, reducing a velocity of the movable object.
