Abstract: An antenna pattern frame according to an aspect of the invention may include: a radiator having an antenna pattern portion transmitting and receiving a signal and a connection terminal portion allowing the signal to be transmitted to and received from a circuit board of an electronic device; a connection portion partially forming the radiator and connecting the antenna pattern portion and the connection terminal portion to be arranged in different planes; a radiator frame manufactured by injection molding on the radiator so that the antenna pattern portion may be provided on one side of the radiator frame and the connection terminal portion may be provided on the other side thereof, while the antenna pattern portion is embedded in the electronic device case; and a contact surface extension provided on the radiator to prevent the radiator from being loosened from the radiator frame during injection molding of the radiator frame, and increasing a contact area with respect to the radiator frame.

Abstract: A distance measuring apparatus according to an aspect of the invention may include: a light source irradiating reference light to measure a distance; a lower reflective mirror reflecting the reference light to irradiate the reference light onto a peripheral obstacle, and reflecting reflected light, rebounded from an obstacle, so that the reflected light moves in an opposite direction along the same optical path as the reference light; a sensor lens arranged above the lower reflective mirror, converting the reference light into parallel light beams and focusing the reflected light; an upper reflective mirror arranged above the sensor lens and switching an optical path of the reflected light; and an optical sensor receiving the reflected light having the optical path thereof switched by the upper reflective mirror, wherein the upper reflective mirror reflects back the reflected light, focused after passing through the sensor lens, in an opposite direction to a moving direction thereof so that a focus of the ref

Abstract: A Three Dimensional (3D) space scanner can obtain spatial data by scanning a mobile object not only in the horizontal direction but also in the vertical direction using a mirror that is driven to rotate as well as to tilt.

Abstract: A space scanner for an autonomous mobile device can obtain spatial data by scanning not only in the horizontal direction but also in the vertical direction of the mobile device using a mirror configured to rotate as well as to tilt and thereby can ensure autonomous driving.

Abstract: A lens module includes a first lens, a second lens, a spacer, a seating part, and a protrusion part. The first lens includes a lens surface and a rib. The second lens is laminated on the first lens. The spacer maintains a predetermined interval between the first lens and the second lens. The seating part is disposed between the lens surface of the first lens and the rib and allows the spacer to be seated on the upper part of the first lens. The protrusion part includes a plurality of protrusions protruded from an undersurface of the spacer, which allow a height of the spacer seated on the seating part to change when the spacer is decentered.

Abstract: There is provided an imaging lens including: a transparent substrate; an upper lens disposed on a top of the transparent substrate; and a lower lens disposed on a bottom of the transparent substrate to correspond to the upper lens, wherein one of the upper and lower lenses includes a lens element and a partition wall formed higher than the lens element to surround the lens element. Also, there is provided a method of manufacturing the same. In the imaging lens, the partition wall is replicated together with the lens element on one or both surfaces of the transparent substrate. The partition wall is formed higher than the lens element and has a flat top surface. Therefore, when another lens element is replicated on an opposite surface of the transparent substrate, the previously replicated lens element is prevented from deformation.
