Abstract:
Disclosed herein is a spectacles and sunshade clip assembly. The assembly comprises spectacles including a pair of lens frames connected to each other by means of a bridge, and a pair of the approximately L-shaped hinges affixed to opposite outer ends of the lens frames and adapted to hingedly connect the lens frames to a pair of temple arms, and a sunshade clip including a pair of sunshade lens frames to receive respective sunshade lenses, and a bridge to connect the sunshade lens frames to each other. A respective one of the hinges takes a multi-layered form having upper and lower connecting ribs defining an opening therebetween. To a rear surface of one of the upper and lower connecting ribs of the hinge is affixed a corresponding one of the magnets. The sunshade clip further comprises a pair of L-shaped magnet bars affixed at their front ends to opposite outer ends of the sunshade lens frames. Rear ends of the L-shaped magnet bars extend toward the spectacles.
Abstract:
Disclosed herein is an interchangeable spectacles and sunshade clip assembly, comprising a spectacle frame, spectacles and a sunshade clip. The spectacle frame includes a frame bar integrally formed with or hingedly connected to a pair of temple arms so as to serve as a lens frame, a magnet piece extending rearward from the center of the frame bar, and one or more magnets incorporated in the magnet piece. The spectacles include a pair of lenses connected to each other via a bridge, and an approximately U-shaped insert centrally affixed at the bridge to correspond to the magnet piece and having upper and lower insert pieces. One or more magnets are incorporated in one of the upper and lower insert pieces. The sunshade clip includes a pair of sunshade lenses connected to each other via a sunshade bridge, and an approximately U-shaped coupling insert integrally injection molded with the sunshade bridge to correspond to the magnet piece and having upper and lower insert pieces.
Abstract:
Disclosed herein is an assembly of a prescription lens unit and sports-sunglasses. The sports-sunglasses takes the form of goggle type sports-sunglasses including a tinted lens and a sunglass rim, but not limited thereto. The sports-sunglasses is provided with an insert unit, which is fixed to a lower end of the tinted lens and mounted with one or more magnets. The prescription lens unit has a bridge, which is mounted with one or more magnets corresponding to the magnets of the insert unit. With such a configuration, the prescription lens unit is detachably coupled to the sports-sunglasses.
Abstract:
Disclosed herein is a spectacles and sunshade clip assembly using magnets. The magnets serve to detachably attach the sunshade clip to the spectacles. The spectacles comprises a pair of lens frames connected to each other by means of a nose bridge, and temple arms connected, respectively, to the lens frames by means of magnetically-induced hinges. The sunshade clip comprises a pair of sunshade lenses formed by cutting a colored plastic plate into a desired lens form, and a sunshade bridge formed by injection molding and adapted to connect the sunshade lenses to each other. Two magnet ribs are coupled to opposite outer ends of the sunshade lenses to extend in opposite directions. Each of the magnet ribs is configured to substantially coincide with the outer contour of the hinge provided at the spectacles and has a magnet mounted to face the hinge.

Provided is a method for chatting messages by topic based on subscription channel reference in a server. The method may include: receiving a message transmission request from a first user terminal corresponding to a first user to a second user terminal corresponding to a second user; extracting a subscription channel to be referred to by parsing the received message; reading a corresponding client handler with reference to a subscription channel stored in a subscription channel storage; and transmitting a message to the first and second user terminals through the read client handler.
Abstract:
An improved pistonless cylinder, including both single acting and double acting configurations, based on an Aramid fiber reinforced elastomer tubular which is highly stiff in radial direction against radial expansion and elastic in axial extension, so as to form a completely sealed, extendable and retractable pressure chamber and to be able to perform as well as, or better than, most of the conventional hydraulic cylinders in terms of load bearing capacities, maximum stroke distances and service durability. This improved cylinder employs no piston, piston rod, sealing seals or oil based hydraulic fluid, and utilizes non-metal materials to construct the majority of the parts for its extendable and retractable pressure chamber; therefore, this new cylinder can achieve significant weight and fabrication cost reduction. In addition, this new pistonless cylinder uses ordinary liquids, e.g., fresh water or seawater, as its hydraulic fluid, and can work directly as a hydraulic or pneumatic cylinder interchangeably without a need for much, if any, modification.
Abstract:
A plant weeding device according to the present invention includes: a housing having a coupling hole penetrating a center of the housing; a rod penetrating the coupling hole and configured to be resiliently movable and rotatable; a weeding blade coupled to one end of the rod and configured to cooperatively rotate and dig up the soil to remove weeds from plants; and a power means configured to be coupled to or separated from the other end of the rod and configured to rotate the rod.
Abstract:
A wood block module includes: a wood block having a deck groove formed on both sides thereof longitudinally; and a deck base disposed below the wood block, on which the wood block is placed, wherein the deck base may include: a rectangular frame; a core positioned at the center of the frame; a connection bridge extending radially from the core and connecting the core and the frame; an extended part extending from the outer side of the frame in a direction orthogonal to the connection bridge; and a protruded part protruding from the end of the extended part in a direction parallel to the connection bridge and corresponding to the deck groove of the wood block.
Abstract:
A method of analyzing objects in images recorded by a camera of a head mounted device is disclosed. The method comprises performing eye tracking while recording the images; determining a region of interest of an image based upon the eye tracking; generating a bounding box based upon the region of interest; cropping an image based upon the bounding box to generate a cropped image; performing a fine cropping of the cropped image; and detecting an object in the cropped image. An electronic device for analyzing objects in images recorded by a camera of a head mounted device is also disclosed.
