    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 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： 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.

    摘要： 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.

    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.

    摘要翻译： 本发明涉及一种用于无线通信系统的交换机。 在一个实施例中，交换机可以同时处理来自多个移动站的数据并支持全双工，即允许同时接收和发送数据。 交换机可以与该交换机的基本业务集（BSS）中的其他交换机和/或移动台同时进行通信。 交换机可以被认为是其他方法中常用的接入点。 然而，使用交换机的系统不需要使用通常在使用接入点的WLAN通信系统中发现的以太网交换机。 交换机可以以主从方案建立，其中主交换机与其从交换机通信，并且从交换机通过主交换机彼此通信。 如果数据是针对交换机的同一BSS中的移动台，则经由交换机控制器，交换机将数据从接收路径传递到发送路径。 因此，数据不需要离开交换机，然后再次返回到同一个交换机。

    摘要： A hardware looping mechanism and method is described herein for handling any number and/or type of discontinuity instruction that may arise when executing program instructions within a scalar or superscalar processor. For example, the hardware looping mechanism may provide zero-overhead looping for branch instructions, in addition to single loop constructs and multiple loop constructs (which may or may not be nested). Zero-overhead looping may also be provided in special cases, e.g., when servicing an interrupt or executing a branch-out-of-loop instruction. In addition to reducing the number of instructions required to execute a program, as well as the overall time and power consumed during program execution, the hardware looping mechanism described herein may be integrated within any processor architecture without modifying existing program code.
