Methods are described allowing a vector signaling code to encode multi-level data without the significant alphabet size increase known to cause symbol dynamic range compression and thus increased noise susceptibility. By intentionally restricting the number of codewords used, good pin efficiency may be maintained along with improved system signal-to-noise ratio.

In some examples, a system and method for generating a payment instrument are described. The method includes receiving a unique signature that a recipient intends to associate with the payment instrument; verifying that the received feature meets an acceptability criterion; generating a representation of the received signature, wherein the representation is in a form capable of being physically associated with the payment instrument, and wherein association is established by embedding or exposing the representation on the payment instrument; and causing physical generation of the payment instrument having associated therewith the representation of the signature.

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.

A logic circuitry package for a replaceable print apparatus component includes an interface including a power terminal and at least one logic circuit. The at least one logic circuit is configured to respond to communications sent to a first address via the interface and respond to communications sent to a second address via the interface. The at least one logic circuit is configured to in response to a first command sent to the first address, draw a first current on the power terminal; and in response to a hibernate command sent to the first address, respond to communications sent to the second address and draw a second current on the power terminal less than the first current.

An optical head comprises a substrate on which optical elements are arranged in a main scanning direction, a lens unit that transmits light emitted from the optical elements or light entering the optical elements, and a holder that holds the lens unit. The holder has a sidewall extending in the main scanning direction. The sidewall has a hole at a position facing the lens unit. A fixing member is provided in the hole. The fixing member fixes the lens unit to the sidewall.

A replaceable print apparatus component includes a print material reservoir, a print material within the reservoir and a sensing system including an integrated circuit configured to connect to and communicate over a digital bus. The sensing system includes at least one sensor, a digital controller, an analog to digital converter electrically coupled to the digital controller, and a memory array electrically coupled to the digital controller. The digital controller is configured to generate a clock signal for timing operations of the integrated circuit. The operations include initiating the at least one sensor based on values stored in the memory array and generating outputs of the at least one sensor via the analog to digital converter.

A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit. The at least one logic circuit includes a memory storing at least one temperature calculation parameter. The at least one logic circuit is configured to receive, via the interface, a first request to read the at least one temperature calculation parameter; and transmit, via the interface, the at least one temperature calculation parameter in response to the first request. The at least one logic circuit is configured to receive, via the interface, a second request corresponding to a sensor ID; and transmit, via the interface, a digital value in response to the second request. The digital value adjusted based on the at least one temperature calculation parameter corresponds to an absolute temperature of the print apparatus component.

Systems and methods relate generally to aero-based printing. In an example thereof, obtained are unmanned aerial vehicles (UAVs) having a first UAV attached to a guide rail and a second UAV attached to an insert or a carriage guide (“guide”). The guide is configured for coupling into or onto the guide rail for slidable movement with a printhead assembly attached to the guide for movement therewith. The printhead assembly includes at least one colorant material holder. In-flight movement of the guide rail is controlled via the first UAV to a print target. In-flight movement of the second UAV is controlled for engagement of the guide into or onto the guide rail. The second UAV communicates to the printhead assembly for controlled printing responsive in part to movement of the guide by the second UAV relative to the guide rail.
