Publication number: 20240081202Abstract: A sprinkler controller is cooperable with a sprinkler assembly that receives fluid input from a pipe span. The sprinkler controller includes a microcontroller circuit, a motion sensor coupled with the microcontroller circuit, and a valve assembly including a modulator coupled with the microcontroller circuit and a valve coupled with the sprinkler assembly. The valve meters or controls an amount of fluid output from the sprinkler assembly, and the microcontroller circuit is programmed to control the valve assembly based on input from the motion sensor. With a series of sprinkler controllers in a center pivot irrigation system, the drop numbers for each of the sprinkler assemblies can be determined based on input from the motion sensors.Type: ApplicationFiled: March 15, 2022Publication date: March 14, 2024Inventors: Meade M. NEAL, Mark A. Bauman, Craig B. NELSON, Travis A. GRIGGS

Method and apparatus for controlling phase-change ink temperature during a transfer printing process
Patent number: 5502476Abstract: A phase-change ink transfer printing process and apparatus (10) applies a thin layer of a liquid forming an intermediate transfer surface (12) to a heated receiving surface, such as a drum (14). Then an ink-jet printhead (11) deposits a molten ink image (26) onto the heated drum where it cools to the drum temperature and solidifies. After the image is deposited, a print medium (21) is heated by a preheater (27) to a predetermined temperature and fed into a nip (22) formed between the heated drum and an elastomeric transfer roller (23) that is biased toward the drum to form a nip pressure that is about twice the yield strength of the ink image. As the drum turns, the heated print medium is pulled through the nip to transfer and fuse the ink image to the print medium. When in the nip, heat from the drum and print medium combine to heat the ink in accordance with a process window (90), making the ink sufficiently soft and tacky to adhere to the print medium but not to the drum.Type: GrantFiled: April 4, 1994Date of Patent: March 26, 1996Assignee: Tektronix, Inc.Inventors: Meade M.
