Abstract: An automotive radar device and an antenna cover are disclosed. The automotive radar device includes a base, an antenna disposed on the base, and the antenna cover. The antenna cover includes a main portion and an engagement portion connected to the circumference of the main portion. The engagement portion can be engaged to the base such that the main portion covers the antenna. Therein, a thickness of the main portion along a radiation direction of the antenna is equal to half-wavelength corresponding to a center operation frequency of the antenna under a dielectric constant of the main portion. Thereby, energy radiated from the antenna can mostly pass through the main portion without excessive signal attenuation, which solves the insufficient signal intensity due to a protection cover in the prior art. Further, the main portion can be made of flexible and weather resistant material to improve its physical and chemical properties.

The method then infers a target feature set from the favored ranking candidates identified in the iterations.

Abstract: Motion-based control of an electronic device uses an array of at least three reference elements forming a triangle. An image sensor (e.g., a video camera), which may be located on a user-manipulated device, captures an image of the array. The array image has a pattern formed by a nonparallel projection of the reference triangle onto the image sensor. The pattern carries information of the relative position between the image sensor and the reference element array, and changes as the relative position changes. The pattern is identified and used for generating position information, which may express a multidimensional position of the user-manipulated device with respect to three axes describing a translational position, and three rotational axes describing pitch, roll and yaw motions. The control system and method are particularly suitable for videogames.
