Publication number: 20240126103Abstract: A prescription lens insert and methods of use are described, in which flexing a frame of a prescription lens insert, such that left and right rims of the frame are displaced mediolaterally, aligns respective larger ends of two keyhole apertures of the frame with left and right mushroom-shaped connector pegs protruding rearward from a pair of protective glasses. The prescription lens insert is then placed over the left and right connector pegs, such that distal heads of the connector pegs pass through the two keyhole apertures of the frame and the keyhole apertures are disposed adjacent shaft portions of the connector pegs. The frame of the prescription lens insert is then unflexed to align respective smaller ends of the two keyhole apertures with the left and right connector pegs, such that the distal heads prevent removal of the unflexed frame.Type: ApplicationFiled: April 15, 2022Publication date: April 18, 2024Inventors: Ludovic Francis BOINNARD, Marc Guy BLANCHARD, Dennis C. TAN, Jamie OMAN, Michael D. YOUNG

Patent number: 11837402Abstract: A switchable permanent magnetic unit is disclosed. The unit comprises: a housing, first and second permanent magnets, and a conductive coil. The first magnet is mounted within the housing and the second magnet is rotatable between first and second positions and mounted within the housing in a stacked relationship with the first magnet. The unit generates a first level of magnetic flux at a workpiece contact interface when the second magnet is in the first position and a second level of magnetic flux at the interface when the second magnet is in the second position, the second level being greater than the first level. The conductive coil is arranged about the second magnet and generates a magnetic field. A component of the conductive coil's magnetic field is directed from S to N along the second magnet's N-S pole pair when the second magnet is in the first position.Type: GrantFiled: December 7, 2022Date of Patent: December 5, 2023Assignee: MAGSWITCH TECHNOLOGY, INC.Inventors: David H. Morton, Thomas R. Whitt, Michael H. Reed, Michael C. Blanchard
