  • System for detecting and estimating concentrations of gas or liquid analytes
    Patent number: 8024133
    Abstract: A sensor system for detecting and estimating concentrations of various gas or liquid analytes. In an embodiment, the resistances of a set of sensors are measured to provide a set of responses over time where the resistances are indicative of gas or liquid sorption, depending upon the sensors. A concentration vector for the analytes is estimated by satisfying a criterion of goodness using the set of responses. Other embodiments are described and claimed.
    Type: Grant
    Filed: November 26, 2007
    Date of Patent: September 20, 2011
    Assignee: California Institute of Technology

  • Holographic memory using beam steering
    Patent number: 7251066
    Abstract: A method, apparatus, and system provide the ability for storing holograms at high speed. A single laser diode emits a collimated laser beam to both write to and read from a photorefractice crystal. One or more liquid crystal beam steering spatial light modulators (BSSLMs) steer a reference beam, split from the collimated laser beam, at high speed to the photorefractive crystal.
