摘要:
The present invention relates to tunable capacitors, devices including tunable capacitors, and methods of making and using tunable capacitors and devices. One or more secondary tunable capacitors can be connected to a primary capacitor by printing a connector conducting layer or feature to obtain a desired net capacitance. Digitally printing the connector conducting layer allows the number of secondary capacitors connected into the circuit to be determined during the integrated circuit fabrication process, without the need for individual masks connecting the appropriate number of secondary capacitors. This provides an in-process or post-process trimming method to obtain the desired precision and accuracy for capacitors. Various sizes and combinations of secondary capacitors can be connected to obtain high precision capacitors and/or improved matching of capacitance values.

A nonvolatile memory cell is disclosed, having first and second semiconductor islands at the same horizontal level and spaced a predetermined distance apart, the first semiconductor island providing a control gate and the second semiconductor island providing source and drain terminals; a gate dielectric layer on at least part of the first semiconductor island; a tunneling dielectric layer on at least part of the second semiconductor island; a floating gate on at least part of the gate dielectric layer and the tunneling dielectric layer; and a metal layer in electrical contact with the control gate and the source and drain terminals. In one advantageous embodiment, the nonvolatile memory cell may be manufactured using an “all-printed” process technology.

An electronic device, including a substrate, a plurality of first semiconductor islands on the substrate, a plurality of second semiconductor islands on the substrate, a first dielectric film on the first subset of the semiconductor islands, second dielectric film on the second semiconductor islands, and a metal layer in electrical contact with the first and second semiconductor islands. The first semiconductor islands and the first dielectric film contain a first diffusible dopant, and the second semiconductor islands and the second dielectric layer film contain a second diffusible dopant different from the first diffusible dopant. The present electronic device can be manufactured using printing technologies, thereby enabling high-throughput, low-cost manufacturing of electrical circuits on a wide variety of substrates.

An example method of manufacturing a solid brazed laminate structure includes stacking a first lamina on a second lamina with an interfacial spacing between them, aligning mating portions of the first lamina and the second lamina, and introducing a braze material at least partially into the interfacial spacing to join the first lamina and the second lamina together. One example solid brazed laminate structure includes a lock assembly. Another example solid brazed structure includes a gear assembly.

A surveillance system for an ATM utilizing multiple cameras aimed at the user, the card slot, and surrounding areas is disclosed. The cameras are powered and begin to record images after a sensor is activated. The system maintains a buffer of recorded imagery such that when the sensors are activated, the video processing equipment can store a pre-defined amount of time before the sensor is activated. The buffer allows for the video capture of events just prior to the activation of the sensor. A time stamp and any other relevant data from the cameras may also be included with the stored recorded video.
摘要:
A circuit and method of qualified anomaly detection provides detection and triggering on specific analog anomalies and/or digital data within a qualified area of a serial data stream. A start pattern within the serial data stream, such as a packet header, is detected to generate an enable signal. A stop event, such as a packet trailer, a specified digital event, a time interval or the like, is identified to generate a disable signal. The enable and disable signals are combined to produce a qualification signal that allows a trigger circuit to trigger on a specified anomaly within the portion of the serial data stream defined by the qualification signal.

A system and method is provided for the real time auditing of covert data marks. Specific information relating to a product or document is entered into an information cell or shell from a product data file. A high definition, high resolution, high speed inline video system is provided to take specific details from the individual product or document, which details are added to the data cell or shell. Details are then inspected, quality checked, matched in the event there are multiple identifiers (e.g., currency would normally carry two matching sequential numbers), and verified to the product order. This cell or shell is passed to the special design computer/controller through a high speed electronic interface. Information entering the computer/controller is once again verified and matched to the original data as well as the product or document. The cell or shell is converted into a specially created 2-dimensional bar code which is encrypted by the computer/controller and then transformed into a video rip. This video rip is sent to high quality/high resolution production print engines. The encrypted 2-dimensional bar code is imaged directly to the product or document as it is carried past the print imaging engines. The ink also is specially designed and manufactured for this system and process. It is an invisible ink which is unique, durable, permanent and not available commercially (covered under trade secrets). These special inks are well suited for delivery using inkjet technology to efficiently make well formed invisible images at slow to high speed production schemes. The product or document is then sent instantly into a drying scheme (this can be air, forced air, heat, UV Dryer, depending on the printing system selected). After drying there is a final scanning. This scanning equipment is the same scanner design which will be used in the field so that each product or document will be verified with the actual scanning device and programs which will be used in the field. From this final scanning of the 2-dimensional data bar code, a final audited product or document profile is created, as is a database which will be the point of reference in the infrastructure during the life of the product or document. Each time any product or document is scanned at a transaction point, the database will be updated, either in real-time or downloaded from a data collection scanning device. This will build a complete history from the point of manufacture to the moment it is removed from service.
摘要:
First location information related to a location-aware device (514) is gathered. Second location information for a location-unaware device (520) is determined from the first location information. A data structure is created comprising a binding of the second location information and an identifying parameter of the location-unaware device (520). The data structure is provided in a form usable by an application.
