Abstract: A split memory bank may comprise a number of memory matrices forming a memory bank and a shift register in which the shift register physically separates the matrices. An integrated circuit may comprise a number of shift registers and a plurality of memory matrices forming a memory bank in which the matrices are spatially separated by the shift register. An integrated printhead may comprise a number of memory banks each comprising a plurality of memory matrices and a number of shift registers in which each shift register spatially separates a number of the matrices.

Abstract: In some examples, a method of sensing an ink level includes applying a pre-charge voltage to a sense capacitor to charge the sense capacitor with a charge, sharing the charge between the sense capacitor and a reference capacitor, causing a reference voltage at a gate of an evaluation transistor, and determining a resistance from a drain to a source of the evaluation transistor that results from the reference voltage.

Abstract: An integrated circuit (IC) erasable programmable read-only memory (EPROM) structure for a thermal inkjet printhead includes: a fire line to provide fire line data; a select line to provide selecting data; a firing cell coupled to the fire line; an EPROM cell coupled to the fire line; a selector cell coupled to the select line, the firing cell and the EPROM cell; and a data switching circuit to provide address data to the firing cell or the EPROM cell. The data switching circuit and the selector cell selectively enable transfer of the fire line data from the fire line to the firing cell or the EPROM cell as a function of state of the selecting data on the select line and the address data from the data switching circuit.

Abstract: A microfluidic pressure sensor may include a reference chamber, a sensed volume, a microfluidic channel connecting an interior of the reference chamber to an interior of the sensed volume, a volume of liquid contained and movable within the microfluidic channel while occluding the microfluidic channel and a sensor to output signals indicating positioning of the volume of liquid along the microfluidic channel. Positioning of the volume of liquid along microfluidic channel indicates a pressure of the sensed volume.

Abstract: According to examples, an apparatus may include a printhead assembly containing a housing supporting a printhead. The printhead may have nozzles that are to fire droplets of a functional agent onto a layer of build material particles along respective flight paths to form sections of a 3D object from the build material particles, an array of light emission devices to direct respective light beams in the respective flight paths, and an array of photon detectors to detect respective light beams directed from a light source of the array of light emission devices, the light emission devices and the photon detectors being supported on the housing. The apparatus may also include a controller to determine whether any of the nozzles is operating improperly based upon whether the photon detectors detected the light beams and to output an instruction regarding an improperly operating nozzle in response to a determination that the nozzle is operating improperly.

Abstract: According to an example, an apparatus may include an agent delivery device to selectively deliver an agent onto a layer of build material particles. The apparatus may also include an energy source to apply energy onto the layer of build material particles to selectively fuse the build material particles in the layer based upon the locations at which the agent was delivered and a chamber formed of a plurality of walls, in which the agent delivery device and the energy source are housed inside the chamber. The apparatus may further include a vapor source to supply vapor into the chamber to wet the build material particles inside the chamber.

Abstract: An RFID security device for product packaging is disclosed. The security device includes an RFID tag disposed on a first portion of a product package, and a booster antenna disposed on a second portion of the product package. The RFID tag and booster antenna are positioned on the product package so that the RFID tag will be electromagnetically coupled to the booster antenna when the product package is closed, and the RFID tag will be decoupled from the booster antenna when the product package is open.
