    Abstract: In an example, an air filter system includes an air filter and a thermally conductive particulate sensor (TCPS). The TCPS includes a temperature sensor to measure a first temperature of the TCPS at a first time, measure a second temperature of the TCPS at a second time, and provide the measured first temperature and the measured second temperature to a controller. The controller to determine an actual rate of temperature change based on the measured first temperature and the measured second temperature, compare the actual rate of temperature change to a target rate of temperature change, and provide a notification when a difference between the actual rate of temperature change and the target rate of temperature change is greater than an accumulation threshold indicative of a threshold amount of particulate accumulation on the TCPS.

    Abstract: According to an example, a three-dimensional (3D) printer may include a first delivery device to selectively deposit first liquid droplets onto a layer of build materials, in which the first liquid has a fusing radiation absorption property. The 3D printer may also include a fusing radiation generator to selectively emit fusing radiation at multiple ranges of wavelengths and at selected locations to selectively fuse the build materials and a controller to tune a range of wavelengths at which the fusing radiation generator is to emit fusing radiation based upon the fusing radiation absorbing property of the deposited first liquid, to determine the selected locations at which the fusing radiation at the tuned range of wavelengths is to be emitted, and to control the fusing radiation generator to selectively emit fusing radiation at the tuned range of wavelengths and onto the selected locations.

    Abstract: An example memristor includes a first conductive layer, a switching layer, and a second conductive layer. The first conductive layer may include a first conductive material and a second conductive material. The second conductive material may have a higher diffusivity than the first conductive material. The switching layer may be coupled to the first conductive layer and may include a first oxide having the first conductive material and a second oxide having the second conductive material. The second conductive layer may be coupled to the switching layer.

    Abstract: The present subject matter relates to an integrated circuit comprising an erasable programmable read only memory (EPROM) array having a plurality of EPROM cells disposed in rows and columns, wherein one or more EPROM cells located at predetermined positions in the EPROM array are selectively dischargeable. The one or more EPROM cells comprise a EPROM transistor having a first conductive layer to store electrons upon the EPROM transistor being programmed and a control metal oxide semiconductor field-effect transistor (MOSFET) electrically connected to the first conductive layer to provide an electron leakage path to dissipate the electrons stored in the first conductive layer in a predetermined leak time period.

    Abstract: A nozzle firing cell may comprise a firing transistor and a pre-charge transistor having a source and drain coupled between a pre-charge line and a gate of the firing transistor wherein the pre-charge line is routed over the gate of the pre-charge transistor. A fluid ejection device may comprise a circuit comprising a nozzle firing ceil, the nozzle firing cell comprising a firing transistor and a pre-charge transistor having a source and drain coupled between a pre-charge Sine and a gate of the firing transistor in which the pre-charge line is routed over the gate of the pre-charge transistor. A circuit may comprise a number of firing transistors and a number of pre-charge transistors each having a source and drain coupled between a pre-charge line and a gate of one of the firing transistors in which the pre-charge line is routed over each of the gates of the pre-charge transistors.
