  • Publication number: 20150044361
    Abstract: Disclosed herein is a composition for making a thin film comprising a solvent; a plurality of particles; the particles being derived by reacting a metal salt with itself or with a ligand; where the metal salt forms metal oxides and/or metal hydroxides upon reacting with itself or with a ligand; and where the particles have a metal oxide content that is substantially greater than their metal hydroxide content when heated at a temperature of less than or equal to 200° C. Disclosed herein too is a method comprising mixing a metal salt with a solvent to form a reaction mixture; where the metal salt reacts with itself to form metal oxides and metal hydroxides; and where the metal oxide content is substantially greater than the metal hydroxide content at a temperature of less than or equal to 200° C.; adding a pH agent to the reaction mixture; and disposing the reaction mixture on a substrate.

  • Patent number: 8933806
    Abstract: The present invention relates to methods of making capacitors for use in surveillance/identification tags or devices, and methods of using such surveillance/identification devices. The capacitors manufactured according to the methods of the present invention and used in the surveillance/identification devices described herein comprise printed conductive and dielectric layers. The methods and devices of the present invention improve the manufacturing tolerances associated with conventional metal-plastic-metal capacitor, as well as the deactivation reliability of the capacitor used in a surveillance/identification tag or device.

  • Patent number: 8912890
    Abstract: The disclosure relates to surveillance and/or identification devices having capacitors connected in parallel or in series, and methods of making and using such devices. Devices with capacitors connected in parallel, where one capacitor is fabricated with a relatively thick capacitor dielectric and another is fabricated with a relatively thin capacitor dielectric achieve both a high-precision capacitance and a low breakdown voltage for relatively easy surveillance tag deactivation. Devices with capacitors connected in series result in increased lateral dimensions of a small capacitor. This makes the capacitor easier to fabricate using techniques that may have relatively limited resolution capabilities.

  • Publication number: 20130315592
    Abstract: The disclosure relates to a method of configuring end-to-end ODUj (lower order ODU) network trails across OTN (Optical Transport Network), in which the tributary port number (TPN) of the lower order ODUj inside higher order ODUk is specified. The time-slot value associated with the TPN is not to be specified by the user. The time-slots are dynamically allocated on the transmit side. On the receive side, there would be a capability in the ODUk adaptation sink function to find the set of time-slots associated with the TPN based on the received multiplex structure identifier (MSI). That is for an ODUj entity with a fixed TPN, the transmitted time-slots can change and the receive end can detect this change and based on that de-multiplex the ODUj from the ODUk.

  • Patent number: 8471308
    Abstract: Process variation-tolerant diodes and diode-connected thin film transistors (TFTs), printed or patterned structures (e.g., circuitry) containing such diodes and TFTs, methods of making the same, and applications of the same for identification tags and sensors are disclosed. A patterned structure comprising a complementary pair of diodes or diode-connected TFTs in series can stabilize the threshold voltage (Vt) of a diode manufactured using printing or laser writing techniques. The present invention advantageously utilizes the separation between the Vt of an NMOS TFT (Vtn) and the Vt of a PMOS TFT (Vtp) to establish and/or improve stability of a forward voltage drop across a printed or laser-written diode. Further applications of the present invention relate to reference voltage generators, voltage clamp circuits, methods of controlling voltages on related or differential signal transmission lines, and RFID and EAS tags and sensors.
