  • Publication number: 20240289935
    Abstract: The present disclosure generally relates to systems and methods for handling, inspecting, and orienting a mask to be placed into a disinfection system. The systems and methods include a computer vision system configured to detect the mask position and calculate an orientation angle of the mask, a first robotic arm configured to lift the mask and adjust the mask position based on the orientation angle, and a second robotic arm configured to hold open the mask for a visual inspection of an internal and an external surface of the mask.

  • Patent number: 11752534
    Abstract: Provided herein are an apparatus and method for bending wire. The apparatus includes a feeding system with at least one feed roller pair and a controllable feed motor, at least one control platform axis, and at least one bending unit. The method includes i) providing the apparatus of claim 1; ii) advancing a wire with the feeding system; iii) engaging the wire with the at least one bending unit; iv) bending the wire with the at least one bending unit; v) retracting the at least one bending unit; and optionally repeating steps ii-v to form a desired structure. Also provided herein are algorithms for feeding, engaging, and bending the wire.

  • Patent number: 7595183
    Abstract: The object of the present invention is to find and produce cathepsin L having high activity under neutral to alkaline conditions and at a low temperature range. The present inventors succeeded in discovering novel cathepsin L having activity even at a low temperature range from hepatopancreas of Japanese northern shrimp. The present inventors further determined the gene sequence encoding said novel cathepsin L, thus enabling production thereof by genetic recombination.
