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: A toner cartridge includes a customer replaceable unit monitoring (CRUM) apparatus to store error information of a toner injection process of the toner cartridge using a toner refill apparatus. Based on the error information not being stored in the CRUM apparatus, an availability of a refill operation of the toner cartridge is identified based on a predetermined first reference value and an amount of toner detected in the toner cartridge, and, based on the error information being stored in the CRUM apparatus, the availability of the refill operation of the toner cartridge is identified based on a predetermined second reference value and the amount of toner detected in the toner cartridge.

Abstract: A print apparatus calibration method is disclosed. The method comprises printing, from each of a plurality of dies of a print head onto a printable substrate, an image in a first color according to a calibration pattern and an image in a second color according to the calibration pattern, the calibration pattern comprising a plurality of patches having a plurality of different densities. The method may comprise scanning, using a scanning unit, the images formed on the printable substrate to generate scanned image data, wherein the images in the first color are scanned by a first scanning module of the scanning unit and the images in the second color are scanned by a second scanning module of the scanning unit. The method may comprise analyzing, using processing apparatus, the scanned image data to identify any differences between printed densities of corresponding patches in different images of the same color. The method may comprise performing a calibration based on the analysis. A print apparatus and a machine-readable medium are also disclosed.

Abstract: An example computing device includes a hinge, a first housing, a first display device disposed in the first housing, second housing rotatably coupled to the first housing via the hinge, a second display device disposed in the second housing, and a connector coupled to the hinge and the second display device. As an example, in response to a rotation of the first housing relative to the second housing, a first end of the second display device is to slide along a surface of the second housing and a second end of the second display device is to slide along a surface of the first housing.

Abstract: In an example, a speaker device may include a first transducer and a second transducer. The first transducer may include a first diaphragm, a first magnetic circuit, and a first voice coil disposed in a magnetic gap of the first magnetic circuit to cause vibration of the first diaphragm. The second transducer may include a second diaphragm, a second magnet circuit, and a second voice coil disposed in a magnetic gap of the second magnetic circuit to cause vibration of the second diaphragm. Further, the speaker device may include a magnetic plate having a first surface coupled to the first transducer and a second surface coupled to the second transducer. The first surface is opposite to the second surface.

Abstract: Secure circuitry detects a latency between when an interrupt occurred and when the interrupt was released in correspondence with handling of the interrupt. The secure circuitry detects an interval between consecutive occurrences of the interrupt. In response to either or both of the latency exceeding a latency limit and the interval exceeding an interval limit, the secure circuitry performs an action.

Abstract: In an example, a method includes operating, by a processor, on object model data and operating, on a processor, on pattern data. The object model data describes at least part of an object to be generated in additive manufacturing and the pattern data describes an object pattern intended to be formed on at least a portion of the part of the object to be generated in additive manufacturing. The method includes determining, by a processor, control data to control a print agent applicator to apply a pattern of fusing agent onto a part of a layer of build material. The pattern of fusing agent comprises a fusing agent area and a gap area that lacks fusing agent. The gap area corresponds to the object pattern such that no fusing agent is applied to a part of the layer of build material that corresponds to the object pattern.

Abstract: A metered volume microfluidic device can include fluid flow microfluidics. The fluid flow microfluidics can include an inflow channel, a metered volume chamber positioned to receive working fluid from the inflow channel, a metered volume outflow channel positioned to receive and direct a metered volume of the working fluid when discharged from the metered volume chamber, and a capillary check valve. The capillary check valve can allow excess working fluid to exit the metered volume chamber when filling the metered volume chamber via the inflow channel. The capillary check valve can also prevent excess working fluid that has passed there through from being reintroduced into the metered volume chamber when the working fluid is discharged into the metered volume outflow channel.
