Abstract: The present application is directed to an anti-theft lug nut assembly and/or system for vehicular wheel use. A lug nut assembly of this application may be used in connection with each wheel of a particular vehicle. In another instance, multiple lug nut assemblies may be used in connection with a single wheel of a vehicle. In such instances, the lug nut assemblies may incorporate a common key member or distinct key members for use with each distinct lug members. Common wrenches and sockets are unable to engage and turn the lug member of this application as a result of the outer surface configuration of the lug member.

Abstract: A system and method for determining impurities in a beverage grade gas such as CO2 or N2 relies on a coupling of FTIR analysis and UV fluorescence detection. Conversion of reduced sulphur present in some impurities to SO2 can be conducted using a furnace. In some cases, CO2 % also is determined.

Abstract: Processor system with a general purpose processor and a cryptographic processor dedicated to performing cryptographic operations and enforcing the security of critical security parameters. The cryptographic processor prevents exposure of critical security parameters outside the cryptographic processor itself, and instead implements a limited scripting engine, which can be used by the general purpose processor to execute operations that require the critical security parameters.

Abstract: A system for tracking one or more subjects for collecting airborne contaminants. The system includes one or more subjects configured to collect air contaminants. Each of the one or more subjects includes an identification tag encoded with identification information identifying the each subject. The system further includes an identification reader configured to decode the identification information encoded within the identification tag of a scanned one of the one or more identification tags. A computer receives and stores the decoded identification information in a record in a database. The computer may also receive and stored an identification code for a user who scanned the scanned identification tag in the record in the database. Additional records in the database are created each time the identification tag of one of the one or more subjects is scanned. The one or more subjects are thereby tracked as they collect airborne contaminants and are incubated.

Abstract: A sample analysis method includes directing a sample that contains one or more SVOC components to a GC column to temporally separate components present in the sample. Output gas from the GC column is expanded into a sample cell. The sample cell is held at a temperature and pressure that are lower than the temperature and pressure at an outlet of the GC column. The volume of the sample cell is sufficiently large for maintaining the one or more SVOC components in a gaseous phase. Infrared spectra of the components in the sample cell are obtained using a Fourier transform infrared spectrometry system.

Abstract: An air sampling device and method of sampling air. The device has a housing body and a retaining assembly for a sampling device. A plenum has a top end coupled to the housing body about an opening such that the plenum is in flow communication with the opening and receives air flow generally from the top end to the bottom end generally along the longitudinal length thereof. A flow connection is coupled to the bottom end of the plenum. A mass flow meter has an input coupled to the flow connection and is in flow communication with the plenum via the flow connection. A blower is configured to draw air past the sampling device, through the opening, and through the plenum, such that a measuring portion of the air flows through the flow connection and through the mass flow meter, which measured the flow rate of the measuring portion.

Abstract: A control system, which may be a Proportional Integral Derivative (PID) control system, controls a component by adjusting the control input and the execution of the control output whenever a change in a state of a component exceeds a certain value. A method is also described.

Abstract: An air sampling device samples air in a controlled environment. The device includes a housing body having a top and a side. An opening is located at the top of the housing body. A retaining assembly retains a sampling device and atrium. The retaining assembly is located at the top of the housing body about the opening. A plenum has a top end and a bottom end, with the top end coupled to the top of the housing body about the opening so that the plenum is in flow communication with the opening. A mass flow meter has an input and an output, with the input coupled to the bottom end of the plenum and in flow communication with the bottom end of the plenum. A blower is located inside the plenum and is configured to draw air past the sampling device, through the opening, through the plenum, and through the mass flow meter. The mass flow meter detects a flow rate of air through the mass flow meter.

Abstract: Examples disclosed herein generally relate to methods and apparatus for the positioning and alignment of an electrodynamic shaker system relative to an excitation point on a structure to be tested. The electrodynamic shaker system includes a base plate, a support plate, and a locking mechanism. The base plate comprises a plurality of rollable ball transfer units coupled to the base plate. The support plate, supporting an electrodynamic shaker and trunnion thereon, is seated on the ball transfer units of the base plate such that the support plate may be aligned relative to the test article via the ball transfer units. Once the electrodynamic shaker system is in the desired location, a flexure of the electrodynamic shaker may be precisely aligned with and coupled to a test article. The electrodynamic shaker system disclosed utilizes no precision components and is tolerant of dust, dirt, and other environmental contaminants typically present in testing locations.

Abstract: Systems and methods for determining interest levels for sporting events and notifying users when the sporting events' interest levels reach threshold levels. One embodiment is a system that includes a processing engine that receives data associated with sporting events and, based on this data, determines interest levels associated with the sporting events. The system also includes a notification engine is coupled to the processing engine. When the processing engine determines that the interest level associated with a particular sporting event has reached a threshold, the notification engine provides notifications to users indicating that the threshold level has been reached.

Abstract: A battery controller with monitoring logic for a model-based battery control of a battery performs battery current characterizing, parameter and state variable abnormality detection, and bound checking of error signals between measured and predicted output variables to generate an output. Switching between closed-loop operation (i.e., the model-based battery control) and open-loop operation (i.e., a traditional battery control) is done based on the output of the monitoring logic such that closed-loop stability and performance are reasonably guaranteed.
