Abstract: In one example in accordance with the present disclosure, a system is described. The system includes at least one directional antenna to 1) emit energy waves towards a mass in which an object is disposed and 2) receive reflected signals from a resonator disposed on the object as the mass is moved relative to the directional antenna. The system also includes a controller to, based on received reflected signals, determine a pose of the object within the mass.

Abstract: In one example in accordance with the present disclosure, a printable ammonium-based chalcogenometalate fluid is described. The fluid includes an ammonium-based chalcogenometalate precursor. The printable ammonium-based chalcogenometalate fluid also includes an aqueous solvent and water. The printable ammonium-based chalcogenometalate fluid is printed onto a substrate. In the presence of heat, the aqueous solvent, water, and ammonium-based chalcogenometalate precursor break down to form a transition metal dichalcogenide having the form MX2.

Abstract: A device includes a P-N junction comprising a monolithic N-type semiconductor layer coupled to a monolithic P-type semiconductor layer. The monolithic N-type semiconductor layer includes a first portion and a second portion. The first portion has a first surface and the second portion has a second surface facing away from the first surface. The monolithic P-type semiconductor layer includes a third portion and a fourth portion. The third portion has a third surface and the fourth portion has a fourth surface facing away from the third surface.

Abstract: In an example implementation, a touch-sensitive illuminating display includes a transparent flexible touch layer, a transparent top conductive layer adjacent the flexible touch layer, a bottom conductive layer, and an electroluminescent layer and variable-thickness dielectric layer sandwiched between the top and bottom conductive layers. Pressure against the flexible touch layer is to reduce the dielectric layer thickness and bring the top and bottom conductive layers closer together, causing the electroluminescent layer to emit light where the pressure is applied.

Abstract: One example of a device includes an antenna, a memristor code comparator, and a controller. The antenna is to receive a wake up signal. The memristor code comparator is to compare the wake up signal to a reference signal. The controller is to provide a trigger signal to wake up the device in response to the wake up signal matching the reference signal.

Abstract: Apparatus, systems, articles of manufacture, and methods to facilitate capacitive code comparing are disclosed. An example apparatus includes a comparator to receive a first portion of a first input and a second portion of a second input, the comparator including a capacitor. The example apparatus further includes a peripheral determination circuit to cause the capacitor to couple the first portion to the second portion; in response to coupling the first portion to the second portion, ground the capacitor; sense a current discharged by the grounded capacitor; and determine a Hamming distance of the first input and the second input based on the sensed current discharged by the capacitor.

Abstract: Graphene printing is disclosed. A disclosed example graphene printing apparatus includes a gas source to cause a graphene precursor gas to flow across a surface of a substrate, and a localized heat source to locally heat portions of the surface to cause graphene to grow at the portions of the surface based on a printing pattern.

Abstract: A multi-fluid kit for three-dimensional printing can include a fusing agent and a nanoparticle-containing agent. The fusing agent can include water and a radiation absorber, where the radiation absorber absorbs radiation energy and converts the radiation energy to heat. The nanoparticle-containing agent can include a liquid vehicle, high density nanoparticles, and a nanoparticle suspension compound selected from the group consisting of terpineol, ethyl cellulose, and a combination thereof.
