  • Three-dimensional (3D) printing
    Patent number: 10647053
    Abstract: In an example of a three-dimensional (3D) printing method, a polymeric build material is applied. A fusing agent is selectively applied on at least a portion of the polymeric build material. A mechanical tailoring agent is selectively applied on at least a region of the portion. The polymeric build material is exposed to radiation, thereby fusing the at least the portion of the polymeric build material in contact with the fusing agent to form a layer. The mechanical tailoring agent forms a composite layer in the at least the region, and the composite layer has a different mechanical property than that of an area of the layer not in contact with the mechanical tailoring agent.

  • Remote comprehensive eye examination system
    Patent number: 10602928
    Abstract: An ophthalmic technician is present with a patient in an exam room to operate eye examination equipment and transmit patient information to remote location. At that remote location, a skilled technician is present to provide the necessary optical care, and may operate the phoropter from the remote location. Using video and/or teleconferencing equipment and a phoropter located in the patient examination room along with management software, the system works to determine the final optical prescription for the patient. That information, coupled with findings from other devices which are integrated with the management software, and that the patient uses locally, are reviewed by a remote-based optometrist or ophthalmologist.

  • Three-dimensional (3D) printing method
    Patent number: 10583612
    Abstract: In a 3D printing method, a coalescent dispersion for forming a 3D object is selected. The dispersion includes an aqueous vehicle and an infrared or near-infrared binding agent dissolved or dispersed therein. The binding agent is a phthalocyanine having a polar group attached to each side chain or a naphthalocyanine having a polar group attached to each side chain. A sinterable material is deposited and heated to a temperature ranging from about 50 C to about 350 C. The dispersion is selectively applied on at least a portion of the sinterable material. The sinterable material and the dispersion applied thereon are exposed to infrared or near-infrared radiation. The binding agent absorbs the radiation and converts it to thermal energy. At least the portion of the sinterable material in contact with the binding agent is at least cured to form a first layer of the 3D object.
