20100237958 | FEED-BACK AND FEED-FORWARD SYSTEMS AND METHODS TO REDUCE OSCILLATOR PHASE-NOISE - Systems, methods, and apparatus are described that provide for low phase-noise, spectrally-pure, and low-jitter signals from electrical oscillators. An aspect of the present disclosure includes utilization of an open-loop feed-forward phase-noise cancellation scheme to cancel phase noise, or jitter, of an electrical oscillator. Phase noise can be measured and then subtracted, with the phase noise measurement and subtraction being performed at a speed faster than phase noise variations of the oscillator. Another aspect of the present disclosure includes use of a feedback scheme for phase noise reduction. A feedback scheme can be used alone or in conjunction with a feed-forward scheme. Related phase-noise cancellation and/or reduction methods are described. Notch filter and RF amplifier circuits are also described. | 09-23-2010 |

20130088707 | METHOD AND SYSTEM FOR CRACK DETECTION - A system and method for crack detection in an object using a first and a second beam of light. According to the method, a surface of the object is scanned by directing onto the object a first and a second beam of light. The first beam of light forms a localized grating pattern on the scanned surface and the second beam of light probes the scanned surface where the localized grating pattern is formed. A reflected probing beam is received. The reflected probing beam comprises a reflection of the second beam of light from the scanned surface where the localized grating pattern is formed. The reflected probing beam is analyzed to detect a signature of a crack in the object. | 04-11-2013 |
20130103440 | METHOD AND SYSTEM FOR FINANCIAL MODELING OF RETROFITTING COST OF AN ENERGY SYSTEM - A system and method for financial modeling of energy efficiency retrofitting cost of an energy system. According to the method, using a monitoring and evaluation system, signals from a number of sensors positioned in predetermined locations of a structure considered for energy efficiency retrofitting are received. The received signals are compared with benchmarks retrieved from a benchmark database. Using results of the comparison, one or more energy consuming components of the structure are identified as candidates for retrofitting. Based on a normalized payback time or other rate of return approach determined by using data retrieved from a retrofit-cost database, a financing model, in relation to an interest rate, for evaluating a cost of retrofitting the one or more component is provided. | 04-25-2013 |
