20090158606 | MULTI-REEL MARKING APPARATUS - A multi-line chalk reel is disclosed that may be comprised of three or more line reels disposed in a polar arrangement of parallel but distinct rotation axes that has a single method for engaging and disengaging a single drive arrangement to any one spool. This arrangement provides a variety of advantages, including a package solution of useful dimensions and a low part count to minimize parts in assembly. The single drive arrangement reduces cost, and provides for convenient access to individual spools. | 06-25-2009 |
20130146901 | COMPRESSION VOLUME COMPENSATION - A liquid-filled light emitting diode (LED) bulb including a base, a shell, one or more LEDs, a thermally conductive liquid, and a bladder. The shell is connected to the base and the thermally conductive liquid is held within the shell. The one or more LEDs are disposed within the shell and immersed in the thermally conductive liquid. The bladder is also immersed in the thermally conductive liquid and is configured to compensate for expansion of the thermally conductive liquid. | 06-13-2013 |
20130148355 | LED BULB WITH LIQUID-COOLED DRIVE ELECTRONICS - A liquid-filled light emitting diode (LED) bulb including a stem body, a shell connected to the stem body to form an enclosed volume, and one or more LEDs attached to a support structure and disposed between the shell and the stem body. The LED bulb also includes a driver circuit configured to electrically drive the one or more LEDs. A thermally conductive liquid and a liquid-volume compensation mechanism are also disposed with the enclosed volume. The one or more LEDs and the driver circuit are thermally coupled to the thermally conductive liquid. | 06-13-2013 |
20150075342 | SAFETY MECHANISMS FOR POWER TOOLS, INCLUDING KICKBACK DETECTION SYSTEM WITH TORQUE SENSOR - Various safety systems for power tools, and in particular table saws include detection systems for detecting a dangerous condition relative to a blade of the power tool, reaction systems for taking mitigation action in response to detection of a dangerous condition. The safety system may detect, prevent, and/or mitigate a dangerous condition associated with the power tool. | 03-19-2015 |
20150075343 | SAFETY MECHANISMS FOR POWER TOOLS, INCLUDING MAGNETORHELOGICAL BRAKE FOR BLADE - Various safety systems for power tools, and in particular table saws include detection systems for detecting a dangerous condition relative to a blade of the power tool, reaction systems for taking mitigation action in response to detection of a dangerous condition. The safety system may detect, prevent, and/or mitigate a dangerous condition associated with the power tool. | 03-19-2015 |
