  • Patent number: 12576185
    Abstract: The hyaluronic acid filler according to the present invention exhibits improved high viscoelastic flow characteristics, and has advantages of monophasic hyaluronic acid fillers and biphasic hyaluronic acid fillers together, and therefore it maintains the shape while having low moving possibility when injecting into skin, and thus it is excellent when used for improving wrinkles, augmentation of soft tissues such as cheeks, breast, nose, lips and hips, etc., and correcting contours, and the duration time in the human body is increased and side effects are small, even if a small amount of crosslinking agent is used during the preparation process.

  • Patent number: 12572701
    Abstract: This application discloses a computing system implementing a reliability verification tool to identify a portion of a layout design describing an integrated circuit includes a victim transistor having a gate connected to an aggressor transistor. The reliability verification tool can extract a resistance network for connections between the victim transistor and the aggressor transistor, and simulate the resistive network to determine connectivity between the wells of the victim transistor and the aggressor transistor occurs prior to the victim transistor having a gate connected to an aggressor transistor.

  • Publication number: 20220040383
    Abstract: The present invention relates to a filler comprising a hyaluronic acid hydrogel having a lift value in a specific range relative to the unit amount (w/w %) of hyaluronic acid included in a filler, in contrast to the modification degree, and as a result of having said lift value the filler exhibits improved high viscoelasticity flow properties, has the advantages of both monophasic and biphasic hyaluronic acid hydrogel fillers, and thus exhibits good tissue-restoring properties, has low mobility when injected into skin whilst still maintaining the shape thereof for a long time, and has minimized deformation of the hyaluronic acid through the minimization of the use of crosslinkers, and thus the natural form of hyaluronic acid molecules can be maintained, enabling a reduction in the occurrence of immune reactions and side effects, and thus has excellent soft tissue restoration properties, volume expansion properties and wrinkle alleviation properties.

  • Publication number: 20210290819
    Abstract: The hyaluronic acid filler according to the present invention shows improved high lift capability, and thereby not only can maintain its shape for a long time while it is unlikely to move when injected into skin, but also the injection force during injection is very low, and therefore it is excellent in anti-wrinkle, soft-tissue augmentation such as cheeks, breast, nose, lips and hips, and the like or expansion of its volume, and contour correction, and even if a crosslinking agent is used at a small amount in the preparation process, the duration in the human body is increased because of efficient crosslinking reaction and pain of patients is caused less by the reduced injection force.

  • Patent number: 10967822
    Abstract: A vehicle that includes a rear bumper having a license plate well recessed into the rear bumper and a combined lighting assembly disposed at the rear bumper. The combined lighting assembly includes a lighting body having an outward facing portion coupled to a sideward facing portion by a turned portion. The sideward facing portion extends into the license plate well. The combined lighting assembly also includes a rearward facing light having a rearward illumination region directed in the vehicle rearward direction from the outward facing portion and a license plate light having a sideward illumination region directed into the license plate well.

  • Patent number: 10082429
    Abstract: System and method for correcting the potential errors occurring in a fiber optic temperature measurement system are disclosed. In one respect, a dual light sources configuration is provided. The primary light source may illuminate a sensing fiber, and an Anti-Stokes band may be detected. The secondary light source may illuminate a sensing fiber, and a Rayleigh band may be detected, where the Rayleigh band is substantially wide enough to cover the Anti-Stokes band of the primary light source. A ratio between these Anti-Stokes and the Rayleigh bands may be used to measure the temperature and undesired errors due to the perturbations falling on the sensing fiber is continuously corrected.
