20140180604 | METHOD OF SIMULATING THE ABSORPTION OF PLANE WAVES USING FEM SOFTWARE TOOLS - A novel and useful method of visualization by detection of EM radiation being irradiated or reflected from objects in the imager's field of view using Finite Element Method (FEM) simulation software tools. The methodology provides a verification method of antenna operation from an electrical point of view since bolometer performance cannot be estimated using regular antenna parameters such as directivity, gain, impedance matching, etc. as the bolometer does not behave as an antenna but rather behaves as an absorber. An incident wave is triggered on the absorber and the absorption of the bolometer structure is estimated using commercially available Finite Element Method (FEM) software (e.g., ANSYS HFSS, CST Microwave Studio, etc.). How much of the energy is reflected is subsequently measured. The energy which is not reflected is considered to be absorbed by the absorber. | 06-26-2014 |

20140372048 | Data Record Size Reduction at Fixed Information Content - A time-of-flight (TOF) mass spectrometer analyzes a sample producing a time series of data points representing amounts of detected ions per unit time. A spectrometer resolution, a spectrometer digitization time period, and a minimum number points per peak needed to maintain the information content of a peak are received. A peak width value is calculated for each point from the resolution and a time of each point. The calculated peak width value for each point is divided by the minimum number points per peak. A maximum time difference between points for each point is produced. A point is selected based on the digitization time period. Adjacent points of the selected point are found. If a difference between the adjacent points does not exceed a sum of a maximum time differences of the adjacent points, the selected point is deleted to compress the time series. | 12-18-2014 |
