One embodiment of the present invention provides a system for measuring multi-connection performance of a network interface card (NIC) within a server. During operation, a client establishes a connection to a receiver within the server. Next, the client remains in a wait state until a multicast message is received from a control computer. Upon receiving this multicast message, the client starts sending data to and receiving data from the receiver within the server. Note that the control computer waits until every client that is to communicate with the server has established a connection to the server before sending the multicast message. In this way, the system ensures that all client and server computer systems begin sending and receiving data simultaneously, thereby allowing the system to more accurately measure multi-connection performance.

A communication system comprises a receiver, which may generate broadcast coefficients that represent the characteristics of a channel using the channel information encoded in the segment synchronization units. The receiver may also use the channel information encoded in both the segment synchronization units and the field synchronization units to accurately determine the characteristics of a long channel.

An embodiment of the invention is a technique for preamble detection and synchronization. A symbol correlation of a sequence of symbols is computed in a correlation window using one of a time-domain correlation and a frequency-domain correlation. The sequence of symbols is received in an orthogonal frequency division multiple access (OFDMA) wireless communication. A symbol is verified from the symbol correlation. The symbol is one of a preamble symbol and a data symbol.

A peritoneal dialysis device displays on a graphical interface a plurality of parameters and any values currently assigned to the parameters, and in response to a user selecting one of the displayed parameters, allows the user to input a value to be assigned to one of the parameters. A value is set for a number of fills parameter or a dwell time parameter based on the value received from the user.Parameter values are set in a peritoneal dialysis device by receiving from a user a selection of a therapy type, receiving from a user values for a plurality of parameters, calculating a value for a plurality of additional parameters based on the values received from the user, determining whether values for one or more of the plurality of parameters or one or more of the additional parameters do not meet one or more criteria, and, if necessary, updating one or more of the values received from the user so that all of the values for the plurality of parameters and the additional parameters meet all the criteria.

A method of initializing tap coefficients of an equalizer may include estimating impulse response coefficients of a channel through which a received signal traveled based on a known portion of the received signal. The method may also include loading the impulse response coefficients into a channel filter and generating a reference signal. The reference signal may be passed through the channel filter to build a training signal. Tap coefficients of the equalizer may be adjusted based on the training signal from the channel filter and on a delayed version of the reference signal.

A method is provided for detecting leaks in a disposable medical fluid cassette that includes a base and a flexible membrane attached to the base in such a way that the base and the flexible membrane cooperate to at least partially form a fluid passageway. The method includes applying a first force to the flexible membrane, measuring a first physical property of a system that includes the medical fluid cassette a medical fluid pumping machine, removing the first force from the flexible membrane, applying a second force to the flexible membrane, measuring a second physical property of the system, and determining whether the medical fluid cassette leaks based on a comparison of the first physical property and the second physical property.
