A method of analyzing, preferably by laser induced breakdown spectroscopy (LIBS), fluid samples (e.g. liquids, solutions, melts or slurries) that contain soluble and insoluble components of various elemental, molecular and biological components using a pre-characterized, preferably non-magnetic, membrane or plurality of membranes each having different characteristics, such as different porosities. The fluid sample is first deposited on the one or more membranes and the components to be analyzed are retained thereon through filtration or diffusion and then analyzed, such as with LIBS. Different components, such as different sized particles, are fixed on different membranes depending on the characteristics (e.g. pore size) of the corresponding membrane, which provides pre-sorting of the components before LIBS analysis.

The present invention provides a system and method for determining bilirubin levels in an individual based on skin coloration using a smartphone or other personal device and an attached ancillary apparatus. The device, such as a smartphone or tablet, is capable of storing and running software. The device is also coupled to both a camera and light source to obtain data regarding the skin's coloration. Software is installed on the device to control the light source and calculate bilirubin levels in the individual based on the input received from the camera. The ancillary apparatus is a mechanism surrounding the light source and camera that is placed on the skin of the individual when the system is in use. The ancillary apparatus thus creates a light tight seal between the skin, light source and camera, enabling the system to receive the most accurate data from the camera.

An apparatus, method, and computer readable medium for writing data on a highly indestructible material is disclosed. A laser may write data on a first side of a highly indestructible material. The data may then be marked as non-rewriteable. The data may also be written on a second side of the highly indestructible material, with the second side being opposite the first side. The highly indestructible material may comprise a stainless steel storage medium.

An optical sound detection system including: a laser source to generate a laser beam; an optical fiber; an optical sensor aligned to detect a detected portion of a diffraction pattern formed by the laser light emitted from the output coupling port of the optical fiber; and a signal processor to process the signal produced by the optical sensor. The optical fiber includes: a core that includes a photoelastically active material; an input coupling port optically coupled to the laser source to couple the laser beam into the core of the optical fiber; and an output coupling port from which the laser light is emitted after propagating through the core. The optical sensor is adapted to produce a signal corresponding to the detected portion of the diffraction pattern.

A beam deflection technique for simultaneous measurements of the thickness, refractive index and optical absorption of transparent materials using a charge coupled device (CCD) camera is provided.
