  • Patent number: 11121950
    Abstract: An apparatus such as an Optical Network Tester (ONT) may include an embedded script interpreter to interpret a script for testing an optical transponder coupled to the ONT. The ONT may identify a control based on a statement included in the script, and cause, via an electrical interface, an interaction with the optical transponder to occur based on the control. The ONT may generate a first timestamped log entry to indicate a timing of the control, detect a data path event associated with the optical transponder, generate a second timestamped log entry to indicate a timing of the data path event, and determine that the data path event was caused by the control based on the first timestamped log entry and the second timestamped log entry. The ONT may further assess operation of the optical transponder based on the determination that the data path event was caused by the control.

  • Patent number: 10913286
    Abstract: A liquid discharge apparatus includes a liquid discharge head, a pump, tanks, a supply path, liquid supply regulators, a pressure detector, and control circuitry. The liquid supply regulators are provided for each of the tanks and configured to open and block the supply path to regulate supply of a liquid from the tanks to the liquid discharge head. The pressure detector is disposed between the liquid supply regulators and the liquid discharge head in the supply path. The control circuitry is configured to determine a low level tank among the tanks on basis of opening and closing conditions of the liquid supply regulators in a case where the pressure detector detects that a pressure of the supply path is lower than a predetermined value, and control the liquid supply regulators to supply the liquid from at least one tank of the tanks to the liquid discharge head.

  • Patent number: 10875341
    Abstract: A printing apparatus is provided that effectively prevents the risk of ink bleeding so as to obtain a high-quality print result. The printing apparatus includes an inkjet head that ejects droplets of ink using inkjet technique so as to adhere the ink to the medium, and an ultraviolet light source that radiates ultraviolet light. The ink contains a colorant, an ultraviolet absorbent, a resin, and an aqueous solvent that emulsifies or suspends the resin. The ultraviolet light source irradiates the ink adhered to the medium with ultraviolet light to heat the ink to a temperature lower than a boiling point of the ink and high enough to prevent the ink from bleeding, so that the aqueous solvent is at least in part volatilized and removed from the ink.

  • Patent number: 10870289
    Abstract: A recording head in an inkjet recording apparatus forms an image on paper using ink. A first sheet of paper has first and second sides. A second sheet of paper has third and fourth sides. The recording head forms a first image and a first mark image on the first side based on first image data, and then a second image and a second mark image on the second side based on second image data. The first mark image represents a first reference location in a first rectangular region in which the first image is to be formed. The second mark image represents a second reference location in a second rectangular region in which the second image is to be formed. A controller determines an enlargement ratio of the second image to be formed on the fourth side based on a discrepancy between the first and second reference locations.
