Abstract: A radar includes a radome, a circuit board, a shielding cover, and an encapsulation cover. The radome includes a receiving space and a wave transmitting face. The circuit board is received in the receiving space. The circuit board includes a first surface having an antenna area and facing the wave transmitting face. The circuit board further includes a second surface having a connection region. The shielding cover is disposed over the second surface of the circuit board and includes an opening region aligned with the connection region. The encapsulation cover includes at least one connecting element which is electrically connected to the connection region via the opening region. At least one testing element is aligned with and electrically connected to the connection region via the opening region to perform a radar test. Thus, the manufacturing cost is saved, and the testing efficiency is enhanced.

Abstract: An image recognition method includes the steps of: receiving a captured image; acquiring a focusing zone image from a portion of the captured image; processing the captured image and/or the focusing zone image and then making the two images into a batch of image information; and executing an image analysis procedure on the batch of image information to generate an analysis result.

Abstract: A structure for attaching an ultrasound sensor to a side portion of a vehicle includes a bracket via which the ultrasound sensor is attached to face the ground under the floor of the vehicle and to be inclined at a predetermined angle with respect to the horizontal plane such that water drops adhering to the ultrasound sensor flow downward.

Abstract: A hostless automobile reverse radar warning system installed to an automobile includes a reverse signal light power module for supplying an electric power required by the system, a plurality of distance sensing modules installed to an external periphery of the automobile for performing a distance detection to detect external environment conditions of the automobile, producing a distance detection result, and generating a warning signal based on the distance detection result, and a warning module for receiving the warning signal and producing a sound to alert a driver based on the warning signal.

Abstract: In a quick removable position sensor installed onto a steering wheel of a motor vehicle, a transmission mechanism is sheathed onto a steering wheel axle, such that the transmission mechanism and the steering wheel axle can perform a turning movement, and an end of an angular sensor is connected to the steering wheel axle, and another end of the angular sensor is connected to the transmission mechanism, for receiving a turning signal generated and outputted by a turning of the transmission mechanism, and a casing is provided for covering the steering wheel axle, the transmission mechanism and the angular sensor, such that the components in the casing can perform the turning movement and receive the turning signal.

Abstract: The present invention discloses a universal replaceable back radar, wherein a head sleeve and a vehicle-reversing module thereof are separately designed and coated, an ultrasonic head is coupled to the connecting block of the vehicle-reversing module, an angle-adjust pad is also clamped to the connecting block of the vehicle-reversing module, and a big and a small hook platelets each with different heights are separately installed at both sides of one face of the angle-adjust pad and press against the internal face of a downward-tilt or an upward-tilt bumper. The universal replaceable back radar of the present invention can simplify the assemblage thereof and save the coating step thereof and its man-hour.
