Abstract:
Circuits and circuit elements configured to generate a random delay, a monostable oscillator, circuits configured to broadcasting repetitive messages wireless systems, and methods for forming such circuits, devices, and systems are disclosed. The present invention advantageously provides relatively low cost delay generating circuitry based on TFT technology in wireless electronics applications, particularly in RFID applications. Such novel, technically simplified, low cost TFT-based delay generating circuitry enables novel wireless circuits, devices and systems, and methods for producing such circuits, devices and systems.
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.
Abstract:
A memory cell is provided that includes a first conductor, a second conductor, a steering element that is capable of providing substantially unidirectional current flow, and a state change element coupled in series with the steering element. The state change element is capable of retaining a programmed state, and the steering element and state change element are vertically aligned with one another. Other aspects are also provided.

Abstract:
Multi-mode (e.g., EAS and RFID) tags and methods for making and using the same are disclosed. The tag generally includes an antenna, an electronic article surveillance (EAS) function block coupled to the antenna, and one or more identification function blocks coupled to the antenna in parallel with the EAS function block. The method of reading the tag generally includes the steps of applying an electric field to the tag, detecting the tag when the electric field has a relatively low power, and detecting an identification signal from the tag when the electric field has a relatively high power. The present invention advantageously enables a single tag to be used for both inventory and anti-theft purposes, thereby improving inventory management and control at reduced system and/or “per-article” costs.
Abstract:
The present invention 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.
Abstract:
The invention relates to novel bar compositions comprising complexes formed from interaction of multivalent ions and soap. The insoluble complexes permit greater solid contents which counterintuitively, enhance lather (i.e., even if soluble soap is complexed, it is believed more can be used). Further, the complexes enhance rate of wear, hardness, mildness and deposition. The invention further comprises process for enhancing benefits by adding multivalent ions to soap stock during processing.
Abstract:
Metallic nanoparticles are provided which can be used in forming metallic film conductors at reduced temperatures compatible with plastic carriers for the film conductors. This is realized by using a lower molecular weight organic encapsulant of the nanoparticle and thereby reducing the temperature at which the organic encapsulant evaporates. Further, the sintering or melting temperature of the metallic nanoparticle is reduced by using a lower sized nanoparticle, thereby increasing the particle surface area relative to the particle volume and thus reducing the required heat and melting temperature of the particle.
Abstract:
The invention relates to non-aqueous personal wash compositions comprising little or no surfactant but which utilize a foam enhancing system to generate good levels of foam.
