  • Patent number: 10975686
    Abstract: A detection system to detect an object in a blowout prevention system of a production system includes a sensor coupled to the blowout prevention system and configured to send an ultrasonic pulse toward the object. The sensor is further configured to receive a signal including the ultrasonic pulse and noise after the ultrasonic pulse interacts with the object. The detection system also includes a controller coupled to the sensor and configured to identify the ultrasonic pulse in the signal using a first cancellation signal at a first time and a second cancellation signal at a second time. The controller is further configured to determine that the first cancellation signal corresponds to the noise in the signal at the first time, and determine that the second cancellation signal corresponds to the noise in the signal at the second time. The controller is configured to determine a characteristic of the object based on the ultrasonic pulse.

  • Patent number: 10866556
    Abstract: An image forming apparatus, including a process cartridge and a main body with an opening and a cover, is provided. The process cartridge includes a drum cartridge, a toner cartridge, and a switching member. The switching member switches states in the process cartridge between a first state, wherein the toner cartridge is restricted from being detached, and a second state, wherein the toner cartridge is released from the restriction. The process cartridge is movable between an attached position to be placed entirely inside the main body and a detached position to be entirely outside the main body. The main body includes a restrictor to restrict the process cartridge from moving from an intermediate position toward the detached position. While the process cartridge is restricted by the restrictor, a supportive part in the cover supports the process cartridge with the switching member being at least partly placed outside the main body.

  • Patent number: 10732555
    Abstract: An image forming apparatus includes image forming devices, image output devices, an endless conveyor, a transfer device, holders, a detector, and circuitry. The image forming devices include image bearers. The image output devices form latent images on the image bearers. The image forming devices form visible images from the latent images. The transfer device transfers the visible images onto the endless conveyor that conveys the visible images in an image conveyance direction. The holders hold the image forming devices interchangeable at holding positions aligned in the image conveyance direction. The detector detects the visible images. The circuitry compares a first visible image of the visible images formed at a specific holding position of the holding positions with a second visible image of the visible images formed at another holding position of the holding positions on the endless conveyor, to correct misalignment between the first and second visible images.
