Abstract: A developing device includes a conveying member to circulate a developer in a housing, a developer discharge portion extending from one end portion of the housing to form a passage through which surplus developer is discharged from the housing, and a discharge regulation member located on an upstream side of the developer discharge portion with respect to a direction in which the developer is conveyed to the developer discharge portion by the conveying member to partially block a conveying path of the developer. The discharge regulation member includes a lower end portion and an upper end portion arranged apart from a bottom and an upper wall of the conveying path, respectively.

Abstract: A print apparatus is disclosed. The print apparatus includes a photoconductive surface to receive a latent image representative of an image to be printed onto a printable substrate; a charging component to apply a voltage is to be applied to the photoconductive surface as the charging component moves relative to the photoconductive surface; and processing circuitry to receive data indicative of a measurement of a first current resulting from the voltage applied by the charging component; determine, responsive to detecting an increase in the measured first current relative to a reference current, the increase being greater than a first defined threshold current, that there exists a point defect under affecting the latent image; and generate instruction data responsive to determining that there exists a point defect under affecting the latent image. A method and a machine-readable medium are also disclosed.

Abstract: Digital user authentication processes can use both dynamic information presented on a user device associated with an individual as well as a biometric associated with the individual to evaluate an authentication attempt for the individual. The dynamic information can include information such as QR codes, pin numbers, cryptographic keys, colors, and other types of information. The biometric associated with the individual can include facial recognition data, fingerprint data, and other types of biometric data. The digital authentication processes can provide enhanced security features that are both less vulnerable to manipulation and more efficient for users.

Abstract: A device includes at least one well to receive a polymerase chain reaction (PCR) mixture and including a bottom. The bottom includes an electrically resistive sheet which has a relative magnetic permeability no greater than about 1.01, wherein the resistive sheet is to receive a signal from a signal source to cause the resistive sheet to generate heat to form a pulse-controlled amplification, thermal cycling zone in close thermal proximity to the bottom.

Abstract: An example three-dimensional (3D) printer may include a camera to capture a low-resolution thermal image of a build material bed. The 3D printer may include an interpolation engine to generate an interpolated thermal image based on the low-resolution thermal image. The 3D printer may also include a correction engine to enhance fine details of the interpolated thermal image without distorting thermal values from portions of the interpolated thermal image without fine details to produce an enhanced thermal image.
