Abstract: In some aspects, olfactory devices include a housing having a first inlet and a second inlet, an ambient air inlet cartridge defining a channel in fluid communication with the first inlet, and a position sensor. The ambient air inlet cartridge includes a first member defining a first orifice, and a second member moveable relative to the first member, the second member defining a second orifice, where a degree of overlap between the first orifice and the second orifice controls a flow capacity of the channel. The position sensor signals the degree of overlap between the first orifice and the second orifice.

Abstract: The present invention permits identification of biological materials following recovery of DNA using standard techniques by comparing a mathematical characterization of the unknown sequence with the mathematical characterization of DNA sequences of known genera and species. The clinical identification of infectious organisms is required for accurate diagnosis and selection of antimicrobial therapeutics. The invention allows an ab initio approach with the potential for rapid identification of biological materials of unknown origin. The approach provides for identification and classification of emergent or new organisms without previous phenotypic identification. The technique may also be used in monitoring situations where the need exists for classification of material into broad categories of bacteria which could have an immediate impact on bio-terrorism prevention.

Abstract: Techniques are described that may be implemented in an adaptive control device to regulate multiple zone environmental units based upon multiple temperature values and multiple airflow values, where each temperature value and each airflow value is related to the temperature and the airflow in a specific zone. In an implementation, the input interface of the adaptive control device is configured to receive multiple temperature values and multiple air flow values from multiple zone sensors. The adaptive control device may calculate multiple operational values based on the multiple temperature values and the multiple air flow values. An operational value indicates a power state (e.g. power on/power off) for a zone environmental unit's fan, compressor, heater, exhaust fan, and damper. The adaptive control device's output interface is operable to transmit multiple sequencing commands to the plurality of zone environmental units.

Abstract: A tunable terahertz resonator includes a semiconductor substrate and a metal layer contacting a surface of the semiconductor substrate. A depletion layer is formed in the semiconductor substrate near an interface between the metal layer and the semiconductor substrate. A chiral nanostructure is coupled to the substrate or the metal layer, the chiral nanostructure including a conducting or semiconducting material and having an inductance. A bias circuit applies a bias voltage across the metal layer and the semiconductor substrate to control a capacitance of a tunable capacitor that includes the depletion layer. The chiral nanostructure and the tunable capacitor form a tunable resonant circuit. The tunable terahertz resonator can be used in a terahertz radiation emitter or receiver.

Abstract: A mass sensor is provided for determining the mass of small objects. The mass sensor has a plurality of nanostructures attached to a substrate.
