摘要:
A diode pumped solid state laser for producing a high aspect ratio beam comprises a diode pumping array (1) on a diode array mount (3) and optical means for imaging a pump light beam onto a substantially asymmetrical spot with a smooth intensity profile. The pump light beam is pumping a laser medium (4). Both the pump and the lasing mode have strong asymmetries. In combination with the right choice of laser medium (4), this results in high power laser performance. The axis of the pump light beam is adjustable by a simple adjusting means (110) to a defined plane or direction relative to a mounting frame (111) of a diode array pumping device (103). The adjusting means (110) compensates small tolerances on mounting of the diode array (1) and/or at least one optical element (2). The adjusting means include at least one wedged window (127). Because of this adjustment the axis of the light beam lies in a defined plane relative to the mounting frame (111) of the pumping device (103). Therefore the diode array pumping device (103) of a laser is replaceable without any further adjustment.

The invention relates to a trocar system for a minimally invasive work station, comprising an endoscopic instrument (2) having imaging means (3) and a device for transmitting the signals containing the image information to a display unit (6) and, as required, work tools, further comprising a trocar assembly (7 to 16) having a trocar sleeve, which is designed to receive a pin, including imaging means (8, 14), provided with a tip that is permeable to imaging media having different wavelengths, wherein the imaging means are provided to make the work field visible through the distal end of the pin and a device (16) is provided for transmitting the signals containing the image information to a display unit (6). The trocar assembly (7 to 16) and the minimally invasive instrument (3) are provided for separate use and for displaying the respective image information for the same display unit (6). The pin is provided with an on/off switch (13). The display device is equipped to display the image information transmitted by the pin when the pin is switched on and to suppress the display of the image information transmitted by the endoscopic instrument, and to display the information transmitted by the endoscopic instrument when the pin is switched off.

摘要:
This invention comprises a mobile asset cellular device transmission detector equipped, a wireless processing unit, an event recorder, and a digital video recorder. The wireless processing unit includes event recorder interface software, digital video recorder interface software that obtains data from the digital video recorder, Wi-Nav software that obtains data from the Wi-Nav, GPS software that obtains data from the GPS and geo-fence software. The cellular device transmission detector continually checks for cellular device transmissions within the mobile asset and if those transmissions were associated with an impact, rollover, operator action or geo-fence defined location or boundary. When a cellular device transmission was made, the wireless processing unit triggers an episode and sends event recorder information, GPS location and speed, audio and video recordings, and impact and rollover information to a back office.
