Patent number: 11773282Abstract: The present invention relates generally to using upconverting inks for producing highly-resolved patterns for inter alia, security applications. More specifically, the present invention relates to the use of sols (inks) and printing processes that produce well-defined printed features consisting of polymers impregnated with luminescent upconversion nanocrystals. The patterns printed using such inks and processes may exhibit defined shapes, characters of text, and various other types of images.Type: GrantFiled: July 2, 2019Date of Patent: October 3, 2023Assignee: SOUTH DAKOTA BOARD OF REGENTSInventors: Jon Kellar, P. Stanley May, William Cross, Jeevan Meruga, Tyler Blumenthal

Patent number: 11568161Abstract: An improved system and method for reading an upconversion response from nanoparticle inks is provided. A is adapted to direct a near-infrared excitation wavelength at a readable indicia, resulting in a near-infrared emission wavelength created by the upconverting nanoparticle inks. A short pass filter may filter the near-infrared excitation wavelength. A camera is in operable communication with the short pass filter and receives the near-infrared emission wavelength of the readable indicia. The system may further include an integrated circuit adapted to receive the near-infrared emission wavelength from the camera and generate a corresponding signal. A readable application may be in operable communication with the integrated circuit. The readable application receives the corresponding signal, manipulates the signal, decodes the signal into an output, and displays and/or stores the output.Type: GrantFiled: May 27, 2020Date of Patent: January 31, 2023Assignee: SOUTH DAKOTA BOARD OF REGENTSInventors: David Langerman, Jon Kellar, William Cross, P.

Patent number: 6637480Abstract: A variable volume buffer is employed to conduct a multitude of articles from an elevated supply stream into a container at a lower elevation while maintaining a drop distance for the articles that is shorter than the distance from the source to the bottom of the container. The bottom of the buffer is vertically displaced in response to the height of the articles in the buffer in a continuous or step-wise function to maintain the fill level of the articles in the buffer at substantially a constant drop distance from the source. Upon the bottom of the buffer moving adjacent the bottom of the container, the gate is opened and the buffer is raised to permit the spilling of the articles directly from the buffer and into the container.Type: GrantFiled: May 14, 2002Date of Patent: October 28, 2003Assignee: Han-Tek, Inc.Inventors: Jon Tobin, Kristin Leahy, Stanley May, Timothy Lemley

Patent number: 6032758Abstract: A personal safety device for users, either workers or sportsmen, exposed, for example, to the risk of falling from a height, comprises a body harness (2) including a pair of shoulder straps (4), a pair of leg loops (6), and a positioning strap (22) attached to spaced apart regions of the harness (2) adjacent the waist thereof by way of transfer means (20, 28) reacting between the positioning strap (22) and the harness (2). The means of attachment of the ends of the positioning strap (22) to the harness (2) are disconnectable or displaceable from the harness (2) on the application thereto of a force exceeding a predetermined limiting value, and whereby the transfer means (20, 28) thereupon transmit said force between the positioning strap (22) and an upper region of the harness (2). Such a device provides a positioning system which converts to fulfil an arrest role in the event of an inadvertent fall, and may be used safely either independently of or in combination with other fall arrest systems.Type: GrantFiled: April 30, 1996Date of Patent: March 7, 2000Assignee: Barrow Hepburn Sala LtdInventor: Harry Stanley May
