摘要： 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.
摘要翻译：公开了多模式（例如，EAS和RFID）标签及其制造和使用方法。标签通常包括天线，耦合到天线的电子商品防盗（EAS）功能块，以及与EAS功能块并联耦合到天线的一个或多个识别功能块。读取标签的方法通常包括以下步骤：向电子标签施加电场，当电场具有相对较低的功率时检测标签，并且当电场具有相对较高的电力时检测来自标签的识别信号。本发明有利地使得单个标签能够用于库存和防盗目的，由此改善了在降低的系统和/或“每件物品”成本下的库存管理和控制。

摘要： 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.

摘要： Printed integrated circuitry and attached antenna and/or inductor for sensors, electronic article surveillance (EAS), radio frequency (RF) and/or RF identification (RFID) tags and devices, and methods for its manufacture. The tag generally includes printed integrated circuitry on one carrier and an antenna and/or inductor on another carrier, the integrated circuitry being electrically coupled to the antenna and/or inductor. The method of manufacture generally includes of printing an integrated circuit having a plurality of first pads on a carrier, forming an antenna and/or inductor having a plurality of second pads on a substrate, and attaching at least two of the first pads of the printed integrated circuit to corresponding second pads of the antenna and/or inductor. The present invention advantageously provides a low cost RFID tag capable of operating at MHz frequencies that can be manufactured in a shorter time period than conventional RFID tags that manufacture all active electrical devices on a conventional wafer.

摘要： 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.

摘要： Methods, algorithms, architectures, circuits, and/or systems for managing POR-less integrated circuits are disclosed. The method of validating code from a wireless device can include: (i) broadcasting a signal from a reader to the wireless device, (ii) reading a code transmitted, re-radiated, and/or backscattered from the wireless device, the code having a predetermined quality, characteristic, and/or property, (iii) comparing the code to a reference quality, characteristic, and/or property, and (iv) validating the code when the predetermined quality, characteristic, and/or property matches the reference quality, characteristic, and/or property. Embodiments of the present invention can advantageously provide a reliable approach for validating integrated circuits that do not incorporate a POR circuit, and which therefore may transmit spurious bits of data upon being energized. In addition, embodiments of the present invention advantageously allow an Aloha-type anti-collision function to be implemented in a reader based on POR-less integrated circuits.

摘要： The present invention relates to electrically active devices (e.g., capacitors, transistors, diodes, floating gate memory cells, etc.) having dielectric, conductor, and/or semiconductor layers with smooth and/or dome-shaped profiles and methods of forming such devices by depositing or printing (e.g., inkjet printing) an ink composition that includes a semiconductor, metal, or dielectric precursor. The smooth and/or dome-shaped cross-sectional profile allows for smooth topological transitions without sharp steps, preventing feature discontinuities during deposition and allowing for more complete step coverage of subsequently deposited structures. The inventive profile allows for both the uniform growth of oxide layers by thermal oxidation, and substantially uniform etching rates of the structures. Such oxide layers may have a uniform thickness and provide substantially complete coverage of the underlying electrically active feature. Uniform etching allows for an efficient method of reducing a critical dimension of an electrically active structure by simple isotropic etch.
