| 20110120693 | INTEGRATED EVAPORATIVE COOLER AND FLAT PLATE AIR TO AIR HEAT EXCHANGER - This invention is an integrated system comprised of a flat plate, air-to-air heat exchanger, ducting and controls, and an AZFlow™ direct evaporative cooler in configurations where the system is able to provide air that has been cooled well below the ambient wet-bulb to temperatures approaching the dew point. These include: A) a two stage cooler where one evaporative cooler performs the stage one cooling by direct evaporative cooling, of the ambient air. This air is directed to the secondary side of the air to air heat exchanger where it indirectly and sensibly cools primary air which is then cooled by a second evaporative cooler which is able to produce the desired cool air approaching the dew point; B) an energy recovery cooling system where building exhaust is collected and directed to the secondary side of the air to air heat exchanger where it indirectly and sensibly cools primary air which is then cooled by an evaporative cooler which is able to produce the desired cool air approaching the dew point; C) an indirect evaporative cooler where an evaporative cooler performs direct evaporative cooling of the ambient air. This air is directed to the secondary side of the air to air heat exchanger where it indirectly and sensibly cools primary air. This sensibly cooled primary air can be used as input to a broad number of applications including but not limited to: inlet air to cooling towers producing water chilled to temperatures approaching the dew point which itself has a broad range of uses, and building makeup air in areas other than the most humid where cooling the air below ambient conditions reduces the energy required to maintain the building environment. | 05-26-2011 |

| 20090114369 | AIR TO AIR HEAT EXCHANGER - A compact heat exchanger efficiently and cost-effectively exchanges heat from one gas stream to another through counter flow channels between parallel plates. Foam strips are incorporated to form the sides of the flow channels that allow channeling and directing the flow of air on each side of a plate heat transfer surface in patterns to maximize the heat exchanger's effectiveness and maintain the gap between heat transfer plates and form the pressure boundary at the edge of the heat exchanger. Clips are incorporated in strategic locations of each plate to locate and mechanically connect the plates to one another and to maintain the location of the foam strips. The heat transfer of the heat exchange surfaces are enhanced using rounded dimples and protrusions arranged such that these occur on the top and bottom of the flow channels. | 05-07-2009 |
| 20090178780 | FLAT PLATE HEAT EXCHANGER - An air-to-liquid heat exchanger having a plurality of spaced apart plate units, each unit including a pair of adhesively bonded spaced apart plates forming a liquid flow channel intermediate the adhesively bonded plates for transferring heat from the liquid in the channel to a gas flowing intermediate the spaced apart units. | 07-16-2009 |
| 20090200000 | COOLING TOWER - A dew point cooling tower system utilizes cooled water produced by the system to reduce the wet bulb temperature of ambient air before the ambient air is directed through fill in the cooling tower. | 08-13-2009 |

| 20090281428 | Method and apparatus for examining a body with an ultrasound head - In a method for extracorporeal examination of a body with an ultrasound head, in which a plurality of ultrasound emitters which are placed next to one another and emit ultrasonic radiation in a common central plane of the ultrasound head, and a plurality of ultrasound receivers are arranged in a row, in order to improve the reproducibility of the orientation of the ultrasound head, it is proposed that with the use of prominent points of the body, a geometrical structure which is defined by these prominent points be determined, and the ultrasound head be positioned relative to this geometrical structure in a defined orientation in which the ultrasound examination is performed on the body. An apparatus for performing this method is also described. | 11-12-2009 |

| 20080214932 | Method and surgical navigation system for creating a recess to receive an acetabulum - To facilitate assistance of the operating surgeon when determining the disposition of a receiving cavity in the case of a method and a navigation system for creating a cavity to receive an acetabulum in a navigated pelvic bone with the aid of a navigated tool, it is proposed that the tear-drop point on the pelvic bone is located by means of a navigated scanning instrument, from the position data and the plane of the pelvic inlet of said pelvic bone there is determined a tear-drop plane, which lies perpendicular to said plane of the pelvic inlet and extends parallel to a line connecting the two anterior superior iliac spines and through the scanned tear-drop point, that a reference point is determined at a defined height above the tear-drop plane and in a defined position in the anterior-posterior direction and at a defined spacing from the outer surface of the pelvic bone in the lateral-medial direction, and that the tool is worked into the pelvic bone in a desired direction relative to the reference point until a predetermined disposition of the tool relative to the reference point is reached. | 09-04-2008 |
