20210389641 | ELECTRO-ACTIVE LENSES WITH RAISED RESISTIVE BRIDGES - Resistive bridges can connect many ring electrodes in an electro-active lens with a relatively small number of buss lines. These resistors are usually large to prevent excessive current consumption. Conventionally, they are disposed in the same plane as the ring electrodes, which means that the ring electrodes are spaced farther apart or made discontinuous to accommodate the resistors. But spacing the ring electrodes farther apart or making them discontinuous degrades the lens's optical quality. Placing the ring electrodes and resistors on layers separated by an insulator makes it possible for the ring electrodes to be closer together and continuous with resistance high enough to limit current consumption. It also relaxes constraints on feature sizes and placement during the process used to make the lens. And because the resistors and electrodes are on different planes, they can be formed of materials with different resistivities. | 2021-12-16 |

20210389709 | IMAGE FORMING APPARATUS AND DETECTING METHOD OF IMAGE DENSITY FAILURE - An image forming apparatus includes: a developer carrier; a screw-shaped developer feeder that feeds developer to the developer carrier; an image carrier on which an image is imaged with toner of the developer; a developing current detector that detects developing current between the image carrier and the developer carrier during imaging; and a controller that detects image density failure that is periodic and oblique to a rotation direction of the image carrier. The controller causes a stripe image to be imaged on the image carrier and analyzes change of the developing current with time during imaging of the stripe image, thereby detecting the image density failure. The stripe image has a width in a length direction of the image carrier narrower than a period of a blade of the developer feeder and has a length in the rotation direction longer than a period of the image density failure. | 2021-12-16 |
20210389710 | IMAGE FORMING DEVICE - An image forming device includes an image carrier, a transfer member, a fixing device, a conveyance member, and a controller. The transfer member forms a transfer nip that transfers an image carried on the image carrier to a recording medium. The fixing device fixes the image on the recording medium. The conveyance member is located downstream of the transfer member in a conveyance direction of the recording medium and feeds the recording medium to the fixing device. The controller variably controls position of the conveyance member. | 2021-12-16 |
20210389711 | CONTROLLING VOLTAGE PROFILES - In an example, a method includes printing a set of images by transferring print agent between a roller of a print agent source and an electrophotographic surface in a plurality of transfer operations, wherein the roller is controlled to have a first voltage profile during each of the transfer operations. A variation in optical density which is consistent across the set of printed images may be detected, and a second voltage profile correction may be determined based on the variation in optical density. The method may further comprise printing a subsequent image by transferring print agent between the print agent source roller and the electrophotographic surface in a subsequent transfer operation, wherein the roller is controlled to have the second voltage profile during the subsequent transfer operation. | 2021-12-16 |
20210389712 | IMAGE FORMING SYSTEM, IMAGE INSPECTION DEVICE, ABNORMALITY DETECTION LEVEL SETTING METHOD, AND PROGRAM - An image forming system includes: an image former that forms a printed image on a recording medium on the basis of setting information included in a print job and original image data; an image reader that generates read image data by optically reading the printed image; an abnormality detector that detects an abnormality included in the printed image using the read image data; a storage that stores a plurality of pieces of read image data in each of which the abnormality has been detected as sample image data, and stores at least one feature parameter representing a feature of the print job in association with corresponding sample image data; a hardware processor that searches for a feature parameter and sets an abnormality detection level in the abnormality detector; and an acceptor that accepts user's evaluation for an abnormality included in the displayed sample image data. | 2021-12-16 |
