摘要： A heart valve prosthesis is provided having a self-expanding multi-level frame that supports a valve body comprising a skirt and plurality of coapting leaflets. The frame transitions between a contracted delivery configuration that enables percutaneous transluminal delivery, and an expanded deployed configuration having an asymmetric hourglass shape. The valve body skirt and leaflets are constructed so that the center of coaptation may be selected to reduce horizontal forces applied to the commissures of the valve, and to efficiently distribute and transmit forces along the leaflets and to the frame. Alternatively, the valve body may be used as a surgically implantable replacement valve prosthesis.

摘要： A control system and method for ensuring proper closure of a dual swing gate. The control system employs position sensors for monitoring the position of each gate arm. A “differential position” is maintained between the arms during closing to ensure proper sequencing. The control system regulates the speed of the master arm and the slave arm to ensure that the differential position is maintained throughout the closure process.

摘要： A method and apparatus for testing a plurality of electronic devices on a large area substrate is described. The apparatus includes a prober positioning assembly coupled to a substrate support within a testing chamber. The substrate support is a testing table capable of movement in X, Y and Z axes and the prober positioning assembly is capable of movement relative to the testing table. A prober exchanger is positioned adjacent the testing chamber and facilitates prober transfer through cooperative and relative movement with the prober positioning assembly. A load lock chamber having a single transfer door actuator, an atmospheric substrate lift, and a plurality of substrate alignment members is also described.

摘要： A microfabricated cross flow filter may have multiple filtration stages. The filtration stages may include microfabricated filter barriers and gaps created in a substrate, thereby allowing very tight tolerances in the filter barrier and gap dimensions to be maintained. Using the microfabrication techniques, the filter barriers can be made having arbitrary shapes, and arranged at an angle or curved with respect to the flow direction, making the pressure drop across the filtration stage more uniform in the cross flow direction.

摘要： A method and apparatus for testing a plurality of electronic devices formed on a large area substrate is described. In one embodiment, the apparatus performs a test on the substrate in one linear axis in at least one chamber that is slightly wider than a dimension of the substrate to be tested. Clean room space and process time is minimized due to the smaller dimensions and volume of the system.

摘要： Mechanisms for selecting a set of antennas for use in a wireless communication system are disclosed. The selected set of antennas is for use in communicating data in a wireless local area network (WLAN) comprising an access point and a plurality of mobile stations. The access point includes a baseband chip capable of adapting various radio frequency (RF) units. Each RF unit in turns includes a plurality of RF sub units, each of which connects to a plurality of antennas. The access point thus includes a number of antennas that, together with the RF units and the baseband chip, form a smart antenna. To identify the selected set of antennas to communicate with a particular mobile station, the access point initially uses a first set of antennas each in a RF sub unit. From this first set of antennas, the access point identifies a first set of winner antennas and a first set of non-winner antennas. From the first set of winner antennas, the access point identifies a first set of winner RF sub units each connecting to a winner antenna in the first set of winner antennas. From each winner RF sub unit, the access point identifies a final winner. The access point then uses the final winner antenna in the selected set of antennas. The access point also uses the first set of non-winner antennas in the selected set of antennas.
