    摘要: A method and apparatus is provided for the analysis of gaseous compounds, especially for determining the concentration of a gas or gases in a gas mixture by microwave spectroscopy. Microwave radiation is generated at one or more frequencies the gas is most responsive to, transmitted by antenna, passed through the gas under test, received by antenna, and the absorption and/or reflection of the microwave radiation is measured by means such as digitization and analysis using the FFT spectrum versus energy response generated, the response subsequently used to calculate the gas concentration.

    摘要: A method for detecting, in a real-time manner, a presence or an absence of a an anomaly in or a cyber attack onto a medical apparatus comprises the steps of capturing, with an antenna, one or more emissions of electromagnetic energy from the processing devices within medical apparatus; converting, with a receiver coupled to the antenna, the one or more emissions from an analog to a digital form; generating, with a controller, a digital signal in a time domain; converting, the digital signal from the time domain to a frequency domain, the digital signal containing a signature of cross modulation products from the non-linear attachments; processing, in the frequency domain, the signature of cross modulation products to determine mixing characteristics of the cross modulation products; and detecting, based on the mixing characteristics, the absence or the presence of the anomaly or the cyber attack.
