A media processing system for processing media having differing properties, the media processing system having a base. The base has a base radial alignment portion, a base vertical alignment portion, and a base retention portion. A set of removable media clamps is included, where each of the set of removable media clamps is adapted for the differing properties of the media, each removable media clamp has a removable media clamp radial alignment portion for engaging the base radial alignment portion and radially aligning the removable media clamp with the base, a removable media clamp vertical alignment portion for engaging the base vertical alignment portion and vertically aligning the removable media clamp with the base, and a media engagement portion for engaging the media. The retention portion is controllable by the media processing system to selectively retain and release a mounted one of the removable media clamps without manual intervention.

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.

One embodiment of the present invention provides a system that accommodates different clock frequencies in an Ethernet passive optical network (EPON). The system receives a signal from an optical line terminal (OLT) at an optical network unit (ONU) and derives an OLT clock. The system also maintains a local clock. The system further receives from the OLT an assignment for an upstream transmission window, during which the ONU can transmit an upstream data burst to the OLT based on the local clock. The system adjusts the number of bits of the data burst without affecting the payload data carried in the data burst, thereby allowing the data burst to fit properly within the upstream transmission window and compensating for frequency differences between the local clock and the OLT clock. The system transmits the data burst based on the local clock in the upstream transmission window.

A method for testing a consumer electronics (CE) product that wirelessly receives user commands from an IR remote control includes obtaining command codes from the remote and correlating the command codes to respective functions. A tester can generate a test script designating the functions but the tester is not required to designate the command codes. In this way, the script can be executed by wirelessly transmitting to the CE product command codes corresponding to the functions designated in the script. During script execution, the CE product is queried for health indicia such as memory usage. The CE product sends the product health indicia to a test computer over a USB debug port.

A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable prosthesis frame. The valve may be delivered transluminally or transmyocardially using a thorascopic or other limited access approach using a delivery catheter. Preferably, the initial partial expansion of the valve is performed against the native valve annulus to provide adequate anchoring and positioning of the valve as the remaining portions of the valve expand. The valve may be delivered using a retrograde or antegrade approach. When delivered using a retrograde approach, a delivery catheter with a pull-back sheath may be used, while antegrade delivery is preferably performed with a delivery catheter with a push-forward sheath that releases the proximal end of the valve first.
摘要:
The present invention is related to a switch for use in wireless communication systems. In one embodiment, the switch can concurrently process data from multiple mobile stations and supports full duplex, i.e., allowing receiving and transmitting data at the same time. The switch can concurrently communicate with other switches and/or mobile stations in the basic service set (BSS) of that switch. A switch may be considered an access point commonly used in other approaches. However, systems using the switch do not need to use an Ethernet switch commonly found in WLAN communication systems that use access points. Switches may be set up in a master-slave scheme wherein a master switch communicates with its slave switches, and slave switches communicate with one another through the master switch. If the data is for a mobile station in the same BSS of the switch, then, via a switch controller, the switch passes the data from the receiving path to the transmitting path. As a result, the data does not have to travel out of the switch and then back to the same switch again.
