  • Patent number: 11944313
    Abstract: In some examples, an embolization device includes multiple sections with three-dimensional non-helical structures when deployed at a vascular site. The multiple sections include a first section and one or more second sections that are smaller than the first section. The first section may have a deployed structure configured to anchor the device at a vascular site (e.g., a blood vessel) of a patient while each of the one or more second sections may be formed from loops that configured to pack and obstruct the vascular site. In some cases, the embolization device also includes a third section having a deployed configuration with multiple helical windings or loops is configured to anchor the embolization device at the vascular site.

  • Publication number: 20230002251
    Abstract: A system and method for regulating and absorbing TFT-LCD organic solvent waste liquid in countercurrent are provided. In the system, each of longitudinal offset pipes of absorbing pipes is disposed between a lower filter plate and an upper filter plate, bottom positions of the longitudinal offset pipes are connected with a sinking-recovery pipe, each longitudinal offset pipe is provided with a photoelectric detector, an activated carbon supply pipe is provided with an activated carbon supply device, the sinking-recovery pipe is connected with a solid-liquid separator, and a wet activated carbon conduction mechanism is provided with a heating-separating device. Activated carbon particles in the absorbing pipe with a certain saturation amount are led out in a non-disassembly-replacement method, the saturated activated carbon is subjected to solid-liquid separating and heating degassing, thus the saturated organic solvent is separated and recovered and the activated carbon particles are recycled.

  • Patent number: 5694013
    Abstract: A method for providing a haptic interface between a user held physical device and a computer generated parametric surface determines if a collision has occurred therebetween. If a collision has occurred, a force to apply to the physical device is determined and a force actuation mechanism is activated so as to produce the force at the physical device. If a collision has not occurred, the force actuation mechanism is deactivated. The method is repeated as the physical device is moved through a virtual space in which the parametric surface is modeled. The physical device is capable of transmitting forces in at least three degrees-of-freedom via the force actuation mechanism which is connected thereto. A human operator holding the physical device can thus interact with the surface, which may be a CAD generated surface.
