Abstract: In an example implementation, a substance detection method includes sensing for fluid in a chamber of a substance detection device. When fluid is sensed in the chamber, the method includes sensing again for fluid in the chamber. When no fluid is sensed in the chamber, the method includes initiating a substance detection process.

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.

Abstract: A method that includes selectively ejecting, from a first nozzle, a patterning material on to a surface of a substrate to define an area within to eject a first printable ammonium-based chalcogenometalate fluid; ejecting, from a second nozzle, the first printable ammonium-based chalcogenometalate fluid within the area defined by the patterning material to form a first layer of the printable ammonium-based chalcogenometalate fluid; and heating the first layer of printable ammonium-based chalcogenometalate fluid to dissipate the first printable ammonium-based chalcogenometalate fluid into a transition metal dichalcogenide having the form MX2.

Abstract: A micro-structure transfer system may include a printhead and a pressure control device to control a pressure of fluid coupled with the printhead. The pressure control device forms a meniscus of fluid at a number of nozzles defined within the printhead to pick up a number of micro-structures. A printhead for transferring micro-structures includes a number of fluid chambers, a number of nozzles defined in an orifice plate through which fluid may exit the chambers, and a pressure control device to control a pressure of fluid within each of the chambers. The pressure control device forms a meniscus of the fluid at a number of nozzles defined within the printhead to pick up a number of micro-structures.

Abstract: A micro light-emitting diode (LED) display assembly includes a backplane, a passivation layer on the backplane, a micro LED on the passivation layer, and a non-transparent metal housing on the passivation layer, wherein the housing includes a base portion on the passivation layer, a sidewall portion upwardly extending from the base portion, a cap portion connected at a top of the sidewall portion, an orifice in the cap portion, and a notch in the cap portion and adjacent to the orifice. The assembly also includes a translucent filter positioned in the notch and covering the orifice, and a pocket defined by an enclosed area in between the sidewall portion, the cap portion, the filter, and the passivation layer, wherein the micro LED is encased within the pocket such that light transmitted from the micro LED directly hits and passes through the filter.
