20080218741 | Optical Inspection Apparatus and Method - In one embodiment, a modulation spectroscopy method comprises the steps of directing a probe beam and a pump beam at a sample, modulating the pump beam, and the probe beam is reflected from the sample into a detector. The sample may include a strained semiconductor. The detector may produce as output an electrical signal which comprises a large d.c. signal proportional to reflectance R of the probe beam and a small a.c. modulated signal at the modulation frequency proportional to the modulation of the reflectance ΔR of the probe beam. Both the reflectance R of the probe beam and the modulation of the reflectance ΔR of the probe beam are measured at a multiplicity of probe beam photon energies arising from different wavelengths of the probe beam, to provide a photoreflectance spectrum comprising at least one photoreflectance lineshape. The photoreflectance spectrum is analysed to measure energy differences between interband electronic transitions of the strained semiconductor, and the strain of the strained semiconductor is determined according to said energy differences. | 09-11-2008 |

20130003050 | SYSTEM AND METHOD FOR NONDESTRUCTIVELY MEASURING CONCENTRATION AND THICKNESS OF DOPED SEMICONDUCTOR LAYERS - The disclosure is directed to nondestructive systems and methods for simultaneously measuring active carrier concentration and thickness of one or more doped semiconductor layers. Reflectance signals may be defined as functions of active carrier concentration and thickness varying over different wavelengths and over different incidence angles of analyzing illumination reflected off the surface of an analyzed sample. Systems and methods are provided for collecting a plurality of reflectance signals having either different wavelengths or different incidence angle ranges to extract active carrier density and thickness of one or more doped semiconductor layers. | 01-03-2013 |

20150211221 | Toilet Splash Guard - A toilet splash guard is provided. The present invention is designed to prevent liquid from splashing from the toilet bowl when a male user urinates. The present toilet splash guard comprises a planar shield having an outer edge conforming to the curvature of the toilet bowl and an inner edge defining an open central region through which the user may urinate. At least one U-shaped attachment means is disposed on the planar shield for removably affixing the present invention to the rim of the toilet. Lastly, a handle extends from the planar shield, allowing the user to remove the present invention from the toilet bowl without having to touch any component of the device that has come in contact with the interior of the toilet. | 07-30-2015 |
