  • Publication number: 20200380129
    Abstract: A system and method (referred to as the system) detect infectious code. The system injects a repetitive software code that causes malware in a monitored device to render a detectable direct current power consumption profile. A guide wave generator generates a guide wave signal that establishes an observational window that is applied to data that represent a direct current source power consumption of the monitored device. An extraction device extracts a portion of the data that represent the direct current source power consumption of the monitored device. A deviation engine identifies the malware on the monitored device without processing data associated with a prior identification of the malware or identifying a source of the malware or identifying a location of the malware on the monitored device.

  • Patent number: 10436813
    Abstract: A Surface Plasmon Scanning-Tunneling Chemical Mapping (SPSTM) system is disclosed that determines identification characteristics of a target material. An optical beam source launches an optical beam that propagates through a transparent optical element to a material layer to excite surface plasmons of the material layer. An optical probe with a nanometer-sized tip is positioned over a nanometer-sized region of the target material, which is positioned on the material layer, to measure a probe signal associated only with the surface plasmons that tunnel from the material layer through the nanometer-sized region of the target material and collected by the optical probe. An optical property analyzer is configured to determine at least one optical property associated with the nanometer-sized region based on the probe signal associated with the surface plasmons collected by the optical probe.

  • Patent number: 8789211
    Abstract: A method of analyzing a sample that includes applying a first set of energies at a first set of frequencies to a sample and applying, simultaneously with the applying the first set of energies, a second set of energies at a second set of frequencies, wherein the first set of energies and the second set of energies form a multi-mode coupling. The method further includes detecting an effect of the multi-mode coupling.

  • Publication number: 20110231966
    Abstract: A method for determining chemical characteristics of a sample, the method including directly applying a first acoustic wave at a first frequency to a probe and applying, independent of the directly applying the first acoustic wave, a second acoustic wave at a second frequency to the sample, wherein the first frequency is different than the second frequency and the first acoustic wave and the second acoustic wave are simultaneously applied to the probe and the sample, respectively, and form a coupling. The method further including applying electromagnetic energy to the sample, wherein the electromagnetic energy is absorbed by the sample causing a change in phase of the second acoustic wave. The method further including detecting an effect of the coupling and determining a spectrum of the sample based on the detecting.

  • Patent number: 7939811
    Abstract: Low energy light illumination and either a doped semiconductor surface or a surface-plasmon supporting surface are used in combination for manipulating a fluid on the surface in the absence of any applied electric fields or flow channels. Precise control of fluid flow is achieved by applying focused or tightly collimated low energy light to the surface-fluid interface. In the first embodiment, with an appropriate dopant level in the semiconductor substrate, optically excited charge carriers are made to move to the surface when illuminated. In a second embodiment, with a thin-film noble metal surface on a dispersive substrate, optically excited surface plasmons are created for fluid manipulation. This electrode-less optical control of the Marangoni effect provides re-configurable manipulations of fluid flow, thereby paving the way for reprogrammable microfluidic devices.
