Patent number: 8085399Abstract: A particle detection system uses a reflective optic comprising a curved surface to detect high angle scattered light generated by a particle in a liquid medium, when a laser beam is incident on the particle. When the particles transit the laser beam, light is scattered in all directions and is described by MIE scattering theory for particles about the size of the wavelength of light and larger or Rayleigh Scattering when the particles are smaller than the wavelength of light. By using the reflective optic, the scattered light can be detected over angles that are greater than normally obtainable.Type: GrantFiled: August 3, 2009Date of Patent: December 27, 2011Assignee: JMAR LLCInventors: John A.

Patent number: 7831154Abstract: Systems and methods for use with an optical communication beam are disclosed. The system allows the beam of light to operate at an adequate power level that provides a robust optical link while minimizing any safety risk to humans. The system calibrates and controls the gain for an avalanche photodiode detector (APD). A detector circuit is used to calibrate the APD. Once calibrated, the detector circuit further provides an electrical bias to the APD to process or condition the electrical signal to produce a detector output. The systems and methods disclosed herein attenuate the power level of an incoming communication beam to prevent oversaturation of an APD. The system further provides an alignment signal, which is effective over a wide dynamic range of incoming power levels.Type: GrantFiled: October 21, 2008Date of Patent: November 9, 2010Inventors: James J. Alwan, Paul William Binun, Scott Harris Bloom, Victor J. Chan, Glenn Claude Hoiseth, Hugh Michael O'Brien, IV, Scott Platenberg, Werner Pyka, Raymond D. Rogers

Patent number: 6504634Abstract: A system and method for controlling the power of a transmitter helps to ensure that the transmitted signal is within the dynamic range of the intended receiver. The transmitted signal is received by the receiver. The received signal strength is measured to determine its power level in relation to the dynamic range of the receiver. Where the signal strength is too high, the transmitter is slewed to effectively decrease its pointing accuracy, thereby causing a lower-power portion of the transmitted signal to impinge upon the receiver. Similarly, where the signal strength falls below a desired level, the transmitter is slewed back toward the center-pointing position, effectively increasing its pointing accuracy, and thereby increasing the signal strength received at the receiver.Type: GrantFiled: October 27, 1998Date of Patent: January 7, 2003Assignee: Air Fiber, Inc.Inventors: Victor J.
