    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: 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.
