Abstract: In some examples, a fluidic die includes an arrangement of fluidic elements to dispense a fluid, each fluidic element of the fluidic elements including a fluidic actuator and a fluid chamber. An array of fluid feed holes is arranged in a plurality of dimensions to communicate the fluid with the fluidic elements, where each of multiple fluid feed holes along a first dimension of the plurality of dimensions is distinct from multiple fluid feed holes along a second dimension of the plurality of dimensions. The fluidic die includes first circuit elements operable at a first power supply voltage, the first circuit elements interspersed in regions between the fluidic elements along different axes of the fluidic die. The fluidic die includes second circuit elements operable at a second power supply voltage greater than the first power supply voltage, the second circuit elements comprising active devices and placed in a region outside of a boundary defining a space in which the fluidic elements and the first circuit elements are placed.

Abstract: A memory circuit for a print component including a plurality of I/O pads, including an analog pad, to connect to a plurality of signal paths which communicate operating signals to the print component. The memory circuit includes a controllable selector connected in line with one of the signal paths via the I/O pads, the selector controllable to disconnect the corresponding signal path to the print component, and a memory component to store memory values associated with the print component. A control circuit, in response to a sequence of operating signals received by the I/O pads representing a memory read, to operate the controllable selector to disconnect the signal path to the print component to block the memory read of the print component, and provide an analog signal to the analog pad to provide an analog electrical value at the analog pad representing stored memory values selected by the memory read.

Abstract: In some examples, a non-transitory machine-readable medium stores machine-readable instructions. When executed by a controller of an electronic device, the machine-readable instructions cause the controller to detect a user presence, determine first and second measurements, where the first and the second measurements indicate first and second distances to the user presence, and, responsive to a determination that the second measurement is less than the first measurement and a determination that the second measurement is within a distance threshold, wake the electronic device from a power saving mode.

Abstract: Techniques for providing location identifiers of devices to render image data comprising faces are described. According to an example of the present subject matter, a face present in image data is detected. A contact identifier corresponding to the face is obtained and a location identifier of a device to render image data is sent to the contact identifier.

Abstract: A device comprising a supply, a first portion, a second portion, and a third portion. The supply is to supply a metallized, non-absorptive media along a travel path, which is electrically connectable to a ground element, the metallized media to carry a first polymer structure. The first portion along the travel path is to receive droplets of ink particles within a dielectric, non-aqueous carrier fluid on the first polymer structure on the media to form an image. The second portion is to apply an adhesion-promoting surface treatment, onto the ink particles and the first polymer structure, comprising UV ozone, plasma, or chemical additive. The third portion is to apply, via heat and pressure, a second polymer structure onto the ink particles and the first polymer structure to produce a media assembly.

Abstract: An electroporation system may include a well plate, a dispenser and a dispenser-well positioning system. The well plate may include wells, each of the wells including an interior, a first electrode adjacent the interior and a second electrode adjacent the interior and spaced from the first electrode. The first electrode and the second electrode are to apply an electrostatic field across the well. The dispenser is to dispense a cell having a diameter into each of the wells. The dispenser-well positioning system is to align each well and the dispenser such that the dispenser dispenses the cell into each well at a location spaced from the first electrode and the second electrode by a distance of at least 5 times the diameter of the cell.

Abstract: In an example method for forming three-dimensional (3D) printed electronic parts, a build material is applied. An electronic agent is selectively applied in a plurality of passes on a portion of the build material. A fusing agent is also selectively applied on the portion of the build material. The build material is exposed to radiation in a plurality of heating events. During at least one of the plurality of heating events, the portion of the build material in contact with the fusing agent fuses to form a region of a layer. The region of the layer exhibits an electronic property. An order of the plurality of passes, the selective application of the fusing agent, and the plurality of heating events is controlled to control a mechanical property of the layer and the electronic property of the region.
