    Abstract: A method may include ejecting, from a nozzle, a first printable ammonium-based chalcogenometalate fluid comprising a first dopant onto a substrate to form a layer of the first printable ammonium-based chalcogenometalate fluid; heating, at a first temperature, the layer of first printable ammonium-based chalcogenometalate fluid to dissipate the first printable ammonium-based chalcogenometalate fluid into a transition metal dichalcogenide having the form MX2 with the first dopant distributed therethrough; ejecting, from the nozzle, a second printable ammonium-based chalcogenometalate fluid comprising a second dopant onto the substrate to form a layer of the second printable ammonium-based chalcogenometalate fluid; and heating, at a second and higher temperature, the layers of first and second printable ammonium-based chalcogenometalate fluid.

    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.

    IPC: G06K19/06

    Abstract: In some examples, a controllable read blocking based radio-frequency identification (RFID) device may include a substrate layer, and a trace formed of a conductive material and disposed on, partially within, or fully within the substrate layer. The controllable read blocking based RFID device may further include a controllable read blocking layer disposed on the substrate layer and the trace and including a fluid disposed in the controllable read blocking layer to selectively block or allow passage of electromagnetic waves to the trace to respectively inhibit or allow communication of a RFID reading device with the controllable read blocking based RFID device.

    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: With the purpose of having RFID tags that are cheap to produce and that are environmentally friendly, it is disclosed a method and a system to manufacture chipless RFID tags. The method and system comprises printing a conductive track on a carbon-based substrate and selectively heating the substrate on the parts comprising the conductive track. The printing of the conductive track envisages using an ink comprising at least one of a metal carbide, a metal boride or a metal nitride.
