20090128352 | AUTOMATED HANDS-FREE EVENT INITIATION IN RESPONSE TO POSITION OR OPERATIONAL STATUS OF VEHICLE - The present invention provides a system including a mirror mounted on a vehicle, the mirror being movable between open and closed positions. A motor is provided, the motor being operable to move the mirror to either the open or closed position in response to an actuation signal from an onboard controller. The onboard controller is able to substantially automatically provide the actuation signal to the motor in response to the occurrence of an actuation condition, which is associated with the engaging or disengaging of a transmission of the vehicle. | 05-21-2009 |

20080207787 | Rigid polyurethane foams with increased heat performance - The present invention provides a rigid polyurethane foam made from the reaction product, at an isocyanate index of from about 90 to about 400, of a polyisocyanate, and a polyol component containing about 20 to about 80 wt. %, based on the weight of the polyol component, of a double metal cyanide (DMC)-catalyzed polyether polyol having a number average molecular weight of greater than about 1000 Daltons (Da), about 80 to about 20 wt. %, based on the weight of the polyol component, of a sucrose-based polyol having a functionality of from about 2.5 to about 6 and a molecular weight of from about 350 to less than about 1,000, and about 0 to about 40 wt. %, based on the weight of the polyol component, of a low molecular weight organic compound having a number average molecular weight of less than about 600 Da, in the presence of water, polyvinylchloride (PVC) particles having a diameter of from about 0.1 to about 200 microns, and glass beads having a diameter of from about 40 to about 400 microns (about 270 to about 45 mesh), and optionally, in the presence of at least one of carbon dioxide, surfactants, flame retardants, pigments and catalysts, wherein the rigid polyurethane foam with a density of about 10 to about 25 pcf has a heat sag measured at 102 mm overhang at 121° C. and one hour of less than about 8 mm. The inventive rigid polyurethane foams exhibit increased heat performance (decreased heat sag) while also maintaining impact and rebound strengths. | 08-28-2008 |

20130256514 | MULTI-MODE OPTOELECTRONIC OSCILLATOR - A multi-mode optoelectronic oscillator (MM-OEO) includes an OEO cavity having an input for receiving an RF signal and an RF output. The OEO cavity includes a) a first laser having a first laser output, a second laser having a second laser output, b) a modulator having i) a first input coupled to the first laser output, ii) a second input coupled to the second laser output, iii) a third input, iv) a first modulator output ,and v) a second modulator output, c) a semiconductor optical amplifier (SOA) having an input coupled to the first modulator output and having an SOA amplified output, d) a photodetector coupled to the SOA amplified output and having an output, and e) a coupler having an input coupled to the photodetector output and having a first output coupled to the third modulator input and a second output, whereby an amplified RF signal is produced at the OEO RF output. | 10-03-2013 |
20140270807 | SYSTEM AND METHOD FOR SUPPRESSION OF EVEN-ORDER PHOTODIODE DISTORTIONS - A system for suppressing even-order distortion in a photonic link includes a laser for providing laser light to a first input of a Mach-Zehnder modulator (MZM), where the MZM has a second input for receiving an RF input signal, a third input for applying a DC bias voltage to the MZM, and an optical signal output. A dc-voltage-biased photodiode has an input, coupled to the MZM optical signal output, and a modulated RF signal output. The MZM DC bias voltage is set at a value to generate an even-order distortion amplitude substantially equal to an even-order distortion amplitude from the photodiode and 180 degrees out of phase so as to substantially cancel the photodiode even-order distortion. The invention provides the cancellation of photodiode even-order distortion via predisortion linearization with a MZM biased slightly away from quadrature, employing a single fiber run and a single photodiode. The invention provides an improvement in carrier-to-intermodulation ratio (CIR) upwards of 40 dB. | 09-18-2014 |

20120055293 | Seized Fastener Removal Tool and Set - A tool may loosen seized bolts by sending shock waves into the bolt shank and thread areas via axial blows with a pneumatic hammer on the center of the bolt head prior to removal. The tool may allow impacts to be centered on the bolt head without damaging the bolt head or without worry of the bit jumping off the bolt. The tool may be comprised of a separate driver and one or more sockets. | 03-08-2012 |
