  • Publication number: 20190204371
    Abstract: An apparatus for detecting low level pulses of millimeter wave electromagnetic radiation has an electromagnetic field receiver including: a receiving antenna configured to receive an input signal at one or more frequencies ranging from 10 GHz to 100 GHz, and a diode detector coupled to the receiving antenna, the diode detector providing an output voltage signal in response to the input signal. The apparatus also has an electronic signal processor. This produces an amplified voltage signal. The electronic signal processor also produces from the amplified voltage signal a reduced bandwidth, unipolar voltage signal proportional to a peak power of the input signal. The electronic signal processor uses this to produce an amplified reduced bandwidth, unipolar voltage signal. At least the electronic signal processor is encased in an electronically shielded housing.

  • Patent number: 10267837
    Abstract: The present disclosure is directed to an apparatus for detecting low level pulses of millimeter wave electromagnetic radiation, such as by detecting the presence of weak electromagnetic emissions inside or around an electromagnetic radiation-emitting device, such as a millimeter wave scanner. The apparatus may also be used to assess such emissions and display a graphical and numerical indication of a sensed level of energy density. A hand-held portable apparatus for detecting low levels of electromagnetic radiation as well as a method for detecting low levels of electromagnetic radiation are also provided.

  • Patent number: 5678550
    Abstract: An apparatus and method for detecting electrical activity in areas of tissue. The apparatus (1) includes a main catheter (5), multifibered endoscope (10), light filtering means (30, 42, 52), photodetectors (40, 50) and a signal processor (60). The apparatus is used to detect electrical activity by first infusing both an electrically sensitive dye and an electrically insensitive reference dye into the subject tissue and then detecting the intensity of light emitted from both dyes. The wavelength of light emitted from each dye is different. The intensity of light emitted from each dye is similar for non-electrically active tissue and moving tissue but different for electrically active tissue. The intensity of light from the two dyes as separately recorded by the photodetectors is compared by a signal processor to eliminate noise attributable to movement within the area of tissue and arrive at a accurate calculation of electrical activity within the area of tissue.

  • Patent number: 4588993
    Abstract: A broadband isotropic probe system simultaneously measuring the E- and H-field intensities of rf complex, near-field electromagnetic radiation comprises a set of three mutually orthogonal dipole antennas and a set of three mutually orthogonal loop antennas located within the same volume of space. Each antenna has associated circuitry comprising a frequency-response-shaping filter and diode detector to provide a frequency response which is flat over the desired frequency bandwidth. The lengths of the dipoles are kept electrically small so that the EM fields are not perturbed. The diameters of the loops are kept electrically small so that the E-field pickup will be negligible. Coupling between any of the probe's antennas is also minimized by the use of electrically small antennas. Circuit means based on the use of square law detectors is also provided, the circuit including an arrangement of analog or digital data processing portions leading into a display means and a data recorder.
