20110180701NANOPARTICLE ELECTROSTATIC TRAP - A method of trapping a charged particle. The method includes providing a planar substrate having a conductive surface thereon, the conductive surface having at least one non-conductive region. The method also includes applying a solution to the conductive surface, the solution comprising at least one charged particle. The method further includes applying a voltage of a threshold level to the conductive surface. The method also includes, in response to the voltage, generating an electrostatic field in the solution adjacent to a boundary between the conductive surface and the non-conductive region. The method also includes setting the threshold level of voltage to result in a strength of the electrostatic field sufficient to prevent the particle from crossing the electrostatic field.07-28-2011

20120212739VARIABLE PATH LENGTH PHOTON TRAPPING SPECTROMETER - A system and method of photon trapping spectroscopy to vary the path length of light for use in spectroscopy. The systems and method include a rotating reflector with slits for selectively permitting light to enter and exit into a reflection cavity containing a sample to be analyzed. After entering the cavity, but before exiting, the light is trapped and repeatedly reflects back and forth through a sample, effectively increasing the path length of light through a sample. The effective path length is quickly adjustable by altering the rotation speed of the rotating reflector to alter the time in which the light is trapped within the cavity. The systems and methods provide a spectroscope with a wide dynamic range, low detection limits, and usable with broadband and monochromatic light sources throughout the optical region (ultraviolet to infrared).08-23-2012

20090025443RADIAL ROLLER HEAD - Radial roller head with rollers distributively arranged in a holder under the same angular separations and in axial separations around a roller axis, the roller surfaces of which have an increasing progression in a spiral manner around the circumference in the counter clockwise direction. A gear wheel drive couples the rollers together. A locking device automatically locks into place after each full roller rotation and is released before each roller procedure via a moveable locking element. A drive device turns the rollers after release of the locking device up to the contact of the roller surfaces with a tool, in order to then be further turned through friction therewith. An electromagnet connected with the locking element, is arranged in the radial roller head with an electrical energy source and a switch connecting the energy source with the electromagnets when the switch is actuated via the work piece or another actuating device.01-29-2009
