Abstract: Techniques are generally described for detecting a concentration level of at least one gas. Some example devices may include a sensor including conductive plate on a surface of dielectric including a nanotube layer formed thereon. The conductive plate and the nanotube layer form a resonator that resonates at a frequency in response to an interrogation signal. The nanotube layer may be configured to associate with one or more gas molecules. The frequency at which the resonator resonates may shift according to which gas molecules are associated with the nanotube layer to identify a particular gas. An amount of resonance may be exhibited as a resonant response signal. An amplitude of the resonant response signal may be indicative of the concentration level of the detected gas.

Abstract: A system for storing and retrieving data comprises a memory device, such as a radio frequency tag, having a memory for storing the data, a first identifier stored in the memory, and a machine-readable symbol associated with the memory device. At least a portion of the machine-readable symbol encodes a second identifier logically associable with the first identifier. The machine-readable symbol may be printed on an RF tag, or may be carried by a container that also carries an RF tag. The machine-readable symbol is composed of characters from a machine-readable symbology, and includes a flag character that indicates the existence of a memory device corresponding to the machine-readable symbol. A reader for reading the machine-readable symbol and the memory device conserves power by determining from the flag character whether a memory device is associated with the symbol, prior to operating a memory device reader section of the reader. The reader reads the machine-readable symbol to obtain a symbol identifier, and successively reads each of a number of memory devices to obtain a memory device identifier until a memory device identifier corresponding to the symbol identifier is found. Alternatively, the reader may successively read each of the number of memory devices to obtain each of the memory device identifiers, read the machine-readable symbol to obtain a symbol identifier, and match the symbol identifier to one of the memory device identifiers.

Abstract: A symbology reader uses a linear detector to image a two-dimensional area by scanning the field of view of the linear detector across an image field. In one embodiment, the reader simultaneously decodes data from the linear detector according to two-dimensional techniques and linear and stacked symbology techniques. If the reader identifies a linear or stacked symbology, the two-dimensional processing is interrupted. As the reader scans the field of view of the linear detector across the image field, the scanning mirror simultaneously sweeps a light plane across the image field so that only the imaged region is illuminated, thereby improving the dynamic range of the reader.

Abstract: A method and apparatus is provided for reading two-dimensional patterns, such as matrix symbols or signatures, using moving beam laser scanners to take advantage of the large depth of field inherent in laser scanners. A pixel generating element and a tracking element together create a digitized image of a target symbol by scanning a laser beam across the symbol. As the pixel generating element generates pixel data composing the digitized image, the tracking element tracks the position of the laser beam in the scanning pattern, and generates laser position data indicating the instantaneous position of the laser associated with particular pixels. The laser position data is then stored in a data memory in association with the generated pixel data, and a microprocessor utilizes the stored pixel data and laser position data to create an image of the target symbol.

Abstract: A new bar code symbology in an exemplary embodiment employs three bars (and spaces) within nine modules, similar to Code 93. Fifty-three data characters are defined, including several special mode characters. By employing these special mode characters, together with certain routines, three symbol characters can represent two 8-bit bytes, or one 16-bit word. As a result, the symbology can efficiently encode 8-bit bytes for use in computer processing, or encode 16-bit character sets such as Unicode. Symbology encodes extended channel interpretation (ECI) numbers, provides multiple numeric compression modes, provides a structured append using a single mode character, as well as other features. Additionally, the symbology includes error correction, with a Special Features Flag character indicating use of error correction in a symbol.

Abstract: A method and apparatus for error correction enhancement for machine-readable symbols applies particularly to symbols having symbol characters, repeating characters such as pad characters, and error correction characters derived from the symbol and pad characters. The method and apparatus read a selected symbol where the selected symbol has at least one damaged pad character. After failing to decode the symbol, the method determines that the symbol has at least one damaged pad character and then locates at least two consecutive pad characters in the selected symbol. The method replaces any damaged pad characters, and then again attempts to decode the symbol, using the error correction characters, after the pad characters have been replaced.
