  • Patent number: 8891087
    Abstract: A system and method for visualizing a biological sample. One or more spectra are selected for illuminating the biological sample to indicate one or more chemicals in the biological sample. The biological sample is illuminated with the one or more spectra. Reflected light is analyzed to determine characteristics of the biological sample.
    Type: Grant
    Filed: June 8, 2012
    Date of Patent: November 18, 2014
    Assignee: Digital Light Innovations

  • Patent number: 7495777
    Abstract: A method and apparatus is described for contact-free 3 dimensional-measuring of a moving object with periodic motion. The method and apparatus makes use of the projection of a defined intensity pattern onto the moving object and the recording and analysis of a reflected pattern from the object wherein the intensity pattern projection is synchronized to a characteristic periodic frequency period or sub-period of the moving object.

  • Publication number: 20060195202
    Abstract: An apparatus and method for obtaining data stored in an electronic module within a power tool over a power line cord of the tool, and without any disassembly of the tool being required. An interface subsystem applies a high frequency, low power AC input signal to the power cord of the tool. A controller within the tool recognizes this signal as an indication that the tool is to be placed in a communications mode. The controller modulates a power switching device used for turning on and off the motor of the tool in such a fashion that current pulses are transmitted over the power line cord back to the interface subsystem. The current pulses correspond to tool usage/performance/identification information stored in the electronic module of the tool. This information is interpreted by a current reader circuit of the interface subsystem as binary information which is then transmitted to an external computing device for analysis and/or recording.

  • Publication number: 20050237011
    Abstract: A method for controlling the operation of a motor utilizing a generic motor control module. The method includes sampling at least one motor operating criterion during operation of the motor and executing a generic control algorithm at a predetermined periodic interval. Execution of the algorithm provides a firing angle, duty cycle, or other suitable control function solution for an electronic valve for each periodic interval, thereby controlling the behavior of the motor. Additionally, the method includes firing the electronic valve at the calculated timing during each periodic interval such that the motor functions in accordance with desired motor operational parameters.
