20080236945 | ADJUSTABLE-HEIGHT SAWHORSE - The sawhorse has a body and an adjustable height horizontal load supporting beam vertically movable relatively to the body. A vertically extendible member can be used between the load-supporting beam and the body to adjust the vertical position of the load-supporting beam relative to the body, with an actuator to operate the vertically extendible member. The sawhorse can have a mechanism allowing to adjust the height of the load supporting beam while the sawhorse is supporting a load. An adjustable height unit for use assembled to a sawhorse body is also described. | 10-02-2008 |

20110296562 | METHOD AND DEVICE FOR ACQUIRING SIGNALS IN LASER SCANNING MICROSCOPY - A method for acquiring signals in laser scanning microscopy, includes the steps of: moving a focused optical excitation beam relative to an object to be measured so that the focus point of the beam follows a predetermined path in the space of the object; and acquiring optical measurement signals along the path according to at least one acquisition parameter; characterised in that the path of the excitation beam is determined so as to substantially minimise the variations of the optical properties of at least one portion of the environments crossed by the excitation beam between consecutive acquisitions, and in that at least one acquisition parameter among the acquisition parameters is modulated during the movement of the excitation beam. A device for implementing the method is also described. | 12-01-2011 |

20090146801 | Tuning algorithm for clock source frequency drift - An emergency evacuation and fire safety system has a plurality of signal devices. The clock source frequencies are tuned using the method and system such that the signals flash in synchronization continuously at a preset flashing interval upon detecting an alarm condition. A synchronization signal including a calibrated time position is broadcast at each predetermined time interval to all notification appliances. A time difference is computed between a local time position and the received calibrated time position by each of the notification appliances at each predetermined time interval and tuning the flashing of each of the one or more notification appliances by adjusting the preset flashing interval based on the computed time difference by each of the one or more associated notification appliances. | 06-11-2009 |

20100115865 | TILE ADAPTOR - The present invention relates a novel adaptor to position tiles or tile-like elements within or around a bathing apparatus, or both. The present invention further includes a method of using the tile adaptor for the installation of tiles. In a representative embodiment, the tile adaptor includes one or more flanges along at least one of its sides to allow the installation of tiles of a variety of thicknesses at a number of places. The adaptor is integrated in the final bathing apparatus. One or more adaptors may be positioned on the floor, wall and/or ceiling of the bathing apparatus, depending on the design of the bathing enclosure. Advantageously, the tile adaptor is easy to install and to use, and it may conveniently be manufactured from a lightweight material such as extruded plastic or a synthetic polymer. | 05-13-2010 |
