Abstract: A system and method for estimating free space and assigning free space probabilities in point cloud data associated with an autonomous vehicle traveling on a surface, including taking into account sensor noise, sensor availability, obstacle heights, and distance of obstacles from the sensor. System and method can include determining surface planes and classifying point cloud points according to whether or not the points fall on surface planes, among other factors.

Abstract: Embodiments of the present invention are directed to a total cost of ownership method and system for technology components, applications or business units. The system provides financial reporting costs in information technology terms in order to build a bridge between technology and finance organizations. The method and system utilize data from systems of record for assets and charges, extract this data and deliver output reports and visualizations on the data processing and analysis in order to drive a Total Cost of Ownership for technology components, applications or business units. The method includes bringing data from disparate sources into the computer processor accessing at least one storage medium, validating the data by a Data Quality Engine, processing the data by matching the at least one charge to the at least one asset and performing data analytics and reporting on the Total Cost of Ownership.

Abstract: The present invention comprises a method for excluding the presence of a pulmonary embolism using a combination of a blood test for D-dimer and a carboximetry test measuring the ratio of exhaled CO2 to O2. If the measured D-Dimer value is at or above a threshold indicative of concern and the carboximetry value is equal to or greater than a pre-determined carboximetry ratio threshold, a clinically significant pulmonary embolism, or a pulmonary thrombus above a certain effective size, is unlikely to be present. If the measured D-Dimer value is at or above a threshold indicative of concern and the respiratory analysis yields a carboximetry ratio less than the carboximetry ratio threshold, test results are inconclusive and additional testing may be required to determine whether a clinically significant pulmonary embolism, or a pulmonary thrombus above a specified size is present.

Abstract: The present invention comprises a method for identifying the presence or absence of a pulmonary embolism using a combination of tests and brightline thresholds. The first test is a blood based test measuring D-Dimer concentration and the second test is a respiratory analysis that determines a carboximetry ratio. If the measured D-Dimer value is at or above a threshold indicative of concern and the carboximetry value is equal to or less than a carboximetry ratio threshold, pulmonary embolism is present. If the measured D-Dimer value is at or above a threshold indicative of concern and the respiratory analysis yields a carboximetry ratio greater than the carboximetry ratio threshold, test results are inconclusive and additional testing is required to determine whether a pulmonary embolism is present.

Abstract: A method of dispensing fluid includes three processes. A first one of these processes includes pumping fluid into a resilient variable-volume dispensing chamber. The dispensing chamber is in series with a normally present finite fluid impedance and an output. The impedance is sufficient so as to cause expansion of the dispensing chamber as it receives pumped fluid even while some fluid flows through the output. Another one of these processes includes repeatedly measuring a parameter related to volume of the dispensing chamber over time. A third one of these processes includes controlling the pumping of fluid based on repeated measurements of the parameter to produce a desired fluid flow through the output. A corresponding system for dispensing fluid implements these processes.

Abstract: A system and method for aiding in the diagnosis of a respiratory dysfunction is described. More particularly, a system and method for aiding in the diagnosis of one or more pulmonary embolisms is described. The system and method described herein include a plurality of sensors, a thermal control system, and a controller means coupled to the plurality of sensors and the thermal control system for aiding in the diagnosis of a respiratory dysfunction.

Abstract: Angular discrimination between signals is described. Multiple signals are sampled with multiple signal sensors spatially separated from each other. Respective transform signals are determined that are representative of each sampled signal. If a difference between the transform signals in a given transform kernel bin is greater than a difference threshold, a first transform signal is modified by altering that kernel bin. Then the resulting modified transform signal is inverse transformed.

Abstract: An apparatus comprises a variable acoustic source and a microphone, both acoustically coupled to a volume having a fluid region and an air region. The apparatus also can include a processor to determine a volume of the air region based on signals received from the microphone and the variable acoustic source. A fluid valve is coupled to the processor, and is configured to allow an amount of fluid to exit the fluid region associated with the volume of the air region. An atomizer, coupled to the fluid region, is configured to aerosolize at least a portion of the fluid.

Abstract: An apparatus comprises a detector, a pressure sensor and a processor. The detector is operable to detect light that is scattered by an aerosol that is associated with a pressure. The pressure sensor is operable to measure the pressure. The processor is coupled to the detector and to the pressure sensor, and is configured to receive at least a signal from the detector and the pressure sensor. The processor is further configured to use the received signals to calculate a volume of the first aerosol, and to output an output signal associated with the calculated volume. The various measurements can be repeated and compared, and the output signal can be a feedback signal for metering subsequent amounts of the aerosol, based on the comparison.
