  • Patent number: 10647124
    Abstract: An inkjet recording apparatus includes: a tank having ink chamber; a recording head; a memory storing a count value updated toward a first threshold value in accordance with ejection of ink; a display; an operation interface; a power switching section switched between a first state and a second state; and a controller executes a first inquiry process to: display a first inquiry screen inquiring whether the ink chamber has been refilled with ink; and receive one of a first operation and a second operation. After receiving the first operation, the controller determines when ink has been supplied. In response to determining that ink has been supplied just before the first inquiry process, the controller sets the count value to a first initial value. In response to determining that ink has been supplied during the second state, the controller sets the count value to a second initial value.

  • Patent number: 10603923
    Abstract: A method for detecting defective printing nozzles in an inkjet printing machine includes printing a multi-row printing nozzle test chart formed of horizontal rows of equidistant vertical lines periodically underneath one another, with only printing nozzles in a print head contributing to every row of the test chart corresponding to the horizontal rows. An area coverage element geometrically associated with the test chart is printed, both elements are recorded by an image sensor and analyzed by the computer. The computer analyzes the recorded area coverage element to detect print defects and allocates defects to a region of geometrically close printing nozzles. An analysis of the test chart in the region identifies nozzles causing the defect. Defective printing nozzles are detected based on thresholds, the detected printing nozzles are then compensated, and in the analysis of the recorded area coverage element, influences of the sensor are eliminated by shading correction.

  • Patent number: 10571354
    Abstract: A test chamber is used within a system for testing microelectromechanical systems (MEMS) pressure sensors. The system includes a processor, two air tanks pressurized to different air pressures, a high speed switch mechanism, and the test chamber. The test chamber houses a MEMS pressure sensor to be tested, a control pressure sensor, and a temperature sensor. The MEMS pressure sensor and the control pressure sensor are located in a cavity within the test chamber. The cavity is of minimal size and has a domed inner surface. A response time of the MEMS pressure sensor within the cavity can be characterized by utilizing the system and subjecting the MEMS pressure sensor to a pressure stimulus pulse produced by switching between the two air tanks.
