Abstract: In order to solve the problems of a conventional flat surface wave generator which has limitations on being applied to a curved structure due to more than a certain required thickness of a dielectric material, proposed are a flexible surface wave generator and system and method for surface wave communication using the same where the flexible surface wave generator is bendable by removing a third dielectric material and by making a first and a second dielectric material thin and at the same time reaches communication performance applicable to the ISM band by changing a pattern of a surface wave generation member and by forming a slit in a radiator material, so it is possible to easily establish a surface wave communication system even in environments where a conventional flat surface wave generator is difficult to be applied by being tightly attached to the surface of a metal medium with curvature.

Abstract: Disclosure provides a two-segment electromagnet stirring member, and a two-segment electromagnet semi-solid die-casting apparatus including the same, and a die-casting method using the same. The two-segment electromagnet stirring member includes a plurality of magnetic field generation parts therein, and includes a first electromagnetic stirring part and a second electromagnetic stirring part separated from each other. The first electromagnetic stirring part and the second electromagnetic stirring part are coupled to each other in a ring shape to surround an outer circumferential surface of a sleeve to perform electromagnetic stirring to molten metal in the sleeve, and are coupled to each other so as to position the plurality of magnetic field generation parts at radially equal gaps around the sleeve.

Abstract: An animal feeding robot which releases feed to the outside by action of external force or gravity applied to the robot by an animal. The robot is controlled by wireless internet via a computer program installed in a mobile device or computer. The feed discharge unit therein does not include any electronic or mechanical control device to control the discharge of feed, but only allows the feed to be discharged by the action of a physical force or gravity applied by an animal. The robot has removed the risk that occurs where a power source is exhausted and allows the feed to be discharged by action applied on the robot by an animal if the power source is exhausted during operation of remote control in the absence of the breeder, and minimizes risk of interruption in the feeding cycle.

Abstract: An animal feeding robot, in which a feed discharge unit, where a feed smell discharge outlet for discharging a feed smell that stimulates the olfactory sense of an animal is formed, is installed and which can stimulate the sensitive olfactory sense of an animal to attract the animal's attention and induce the animal's behavior so as to make a contact with the robot even during the period when the robot stops operating, thereby discharging feed as a performance reward. An animal feeding robot which can maximize the remote control management uptime of a robot by minimizing power source consumption via elimination of the use of various power sensors and sound generators with high power source consumption, while being equipped therein with a way for discharging the smell of feed, capable of promoting the animal's voluntary access to and contact with the robot.

Abstract: The invention provides nanodevices or products of manufacture for use as drug delivery vehicles. In one aspect, the invention provides nanodevices or products of manufacture having on-off release mechanisms, e.g., that are “switchable”, or “actuatable” (for example magnetically or ultrasonically switchable), for compounds contained within, e.g., for use as drug delivery nano-vehicles having on-off drug release mechanisms, and their therapeutic applications.
