The present invention relates to a compact for cosmetics comprising an upper case, a lower case rotatably coupled to the upper case and a refill case detachably received in the lower case, wherein the refill case comprises a case mainbody where contents for cosmetics are received; a case cover which opens and closes the case mainbody; and a mesh screen cover having a border rim part which is received in the case mainbody to be tightly received within a wall of the mainbody, and a high elasticity mesh screen which has a border area supported by the border rim part to extend inwardly so as to cover the contents for cosmetics from an outside. Accordingly, expanded space is provided for receiving contents for cosmetics, the contents for cosmetics is prevented from flowing out of the refill case by the high elasticity mesh screen covering the contents for cosmetics, and the contents for cosmetics is prevented from being directly exposed to the outside thus decreasing vaporization when the case is open.

Disclosed is a compact for containing a loose powder, such as cosmetic finishing powder, including a base, a cover, a sifter, and a platform compressible against the sifter. The platform may comprise an inner portion flexibly coupled to an outer portion via a gasket disposed on at least a portion of a bottom surface of the inner portion. The compact may have an open position and a closed position. In the closed position, the cover may apply a downward force on the inner portion, compressing the gasket against the sifter and creating a seal to isolate the loose powder.

The present invention is a container for storing products, comprising a base made substantially of silicon comprising an inner area for containing products, the base having an outer wall of a particular perimeter, the base having a rim at the very top thereof, and a cover made substantially of silicon comprising a wall extending around the outer perimeter thereof which encloses the rim and the top of the base, the cover also having a lip on the inside thereof which is parallel to the wall thereof, whereby when the cover is placed on the base, the rim of the base is gripped between the lip on the inside of the cover and the wall on the cover to hold the cover in place. Due to the fact that the container is comprised substantially of silicon, substantially all of the products placed therein will be useable such that there will be no remnants of the product left over.

A jar and lid assembly that includes a jar assembly configured to hold a product and a base configured to at least partially house the jar. The jar and lid assembly also includes a rotatable lid assembly pivotably coupled to the jar assembly and includes an outer lid portion and an inner lid portion. The rotatable lid assembly further includes a lid ring having: (i) a hinge portion configured to pivot on an axis of the base such that the rotatable lid assembly is pivotable relative to the jar assembly and (ii) a lid ring protruding portion disposed within the gap and a liner disposed on an underside of the inner lid portion and configured to contact the jar when the rotatable lid assembly is in a rotatably closed position. The outer lid portion and the inner lid portion are configured to be movable relative to the lid ring.

The present device relates to a cosmetic container for containing and storing cream type cosmetics. In particular, the cosmetic container has a structure comprising: a lower container 10, partitioned into a plurality of compartments 141, 142, for containing and storing different types of cosmetics in respective compartments; an upper container 20 formed on a cover coupled to the upper end of the lower container 10, wherein the upper container 20 is also partitioned into a plurality of compartments 241, 242 and contains and stores different types of cosmetics in respective compartments; and an upper cover 30 for sealing the upper portion of the upper container 20.

The present invention can magnify a sealing characteristic and prevent deformation of hard rubber by coupling a container body with a rib formed on an external cap and through double-injection molding by an elastomer having a different elastic restoring force from the hard rubber charged and hardened in an injection concave groove of a support body that accommodates an internal container, in order to maximize product reliability by improving a sealing structure of a make-up base container or a cosmetic container and providing a clear air-tight effect since the sealing structure cannot be transformed even in case of long-term use. Further, the invention provides regular and firm adhesion without the unequal distribution of the coupling intensity between internal sealing members when the external cap is closed, such that superior sealing performance is accomplished even in case of long-term use and an aesthetic point on the appearance is increased since an opening and closing means is not necessary, and further, it is possible to solve the unstable storage state which is caused when the opening and closing means is equipped.

This paper studies the sampled-data output feedback fuzzy control issue for active suspension systems via the input delay approach. The vehicle suspension system with uncertainty is approximated by using the Takagi-Sugeno fuzzy model. Since the entire system contains digital controllers, sampled signals from digital devices are modeled as a time-varying delay function. Based on the Lyapunov-Krasovskii theorem with mathematical inequalities, the existence conditions of the sampled-data fuzzy controller are obtained concerning linear matrix inequalities(LMIs). Finally, simulation results provide the effectiveness of the proposed controller.

Robust Sampled-data Output Feedback T-S Fuzzy Control for Vehicle Active Suspension Systems via Input Delay Approach

This paper proposes a robot navigation algorithm for human-following based on trajectory forecasting. In home environments, the target-following task is becoming increasingly important for achieving effective human-robot interaction. However, vision-based human-following methods often suffer from the presence of obstacles. Therefore, we employ EKF-based trajectory forecasting to enable the robot to follow the person when they disappear from the field of view. Based on the occupancy grid map in SLAM, the mobile robots determine the goal location for human-following. When the target remains in vision, the home robots move a location 1 meter in front of the target's position as its goal point. On the other hand, one of the reasonable point in trajectory forecasting is selected when the target disappears from the field of view.

Robot Navigation for Human-Following via Trajectory Forecasting

Robot manipulation has attracted considerable attention in the development of robotic intelligence due to its high applicability in real-world industries. In particular, the importance of visual feedback teleoperation is increasingly emphasized in robotic manipulation because of its potential hazards in industrial manufacturing environments. Teleoperation for robotic manipulation helps manufacturing engineers inspect their workspace safely. In order to check the work environment remotely, the visual information should be transmitted to engineers. In addition, it can be employed for data collection to facilitate the development of imitation learning. In this paper, we propose a visual feedback teleoperation approach for robotic manipulation using 3D printing technology. By sharing the robot's view through visual SLAM and employing ROS2, the actual robot manipulation can be achieved in a manner that replicates the movements of the 3D printed object.

In this paper, we present a new sampled-data <inline-formula> <tex-math notation="LaTeX">$\mathcal {L}_{2}-\mathcal {L}_{\infty }$ </tex-math></inline-formula> filter-based output feedback fuzzy control design technique for active suspension systems subjected to hard constraints. The sampled-data problem of continuous-time suspension systems is solved using an input delay approach. In this manner, the conservatism that occurs when designing filters and controllers is effectively alleviated by using Wirtinger’s inequality with the extended reciprocally convex combination bounding technique. We designed an <inline-formula> <tex-math notation="LaTeX">$\mathcal {L}_{2}-\mathcal {L}_{\infty }$ </tex-math></inline-formula> filter-based output-feedback fuzzy controller by using the Lyapunov–Krasovskii theorem to ensure that the closed-loop system is robust against external disturbances and sampled noise. The results of simulations involving different types of road disturbances and noise demonstrate the effectiveness of the proposed approach.
