    Abstract: A distillation unit for producing potable water using solar radiation is disclosed. The distillation unit includes a heating chamber defining an interior chamber adapted to contain a non-potable liquid for distillation, and a dome-shaped condensing portion having an inner surface and an outer surface, with the condensing portion disposed over the heating chamber such that the heating chamber and the inner surface of the condensing portion are provided in fluid-transfer communication. The distillation unit also includes a pre-heat jacket having a first surface and a second surface and an interior defined therebetween adapted to receive non-potable liquid for distillation therein. The first surface is disposed adjacent the outer surface of the condensing portion, and the pre-heat jacket defines an access entry for introducing non-potable liquid for distillation into the interior of the heating chamber. The distillation unit also includes a trough adjacent for receiving a potable liquid therein.

    Abstract: A power converter that interfaces a motor requiring variable voltage/frequency to a supply network providing a nominally fixed voltage/frequency includes a first rectifier/inverter connected to a stator and a second rectifier/inverter. Both rectifier/inverters are interconnected by a dc link and include switching devices. A filter is connected between the second rectifier/inverter and the network. A first controller for the first rectifier/inverter uses a dc link voltage demand signal indicative of a desired dc link voltage to control the switching devices of the first rectifier/inverter. A second controller for the second rectifier/inverter uses a power demand signal indicative of the level of power to be transferred to the dc link from the network through the second rectifier/inverter, and a voltage demand signal indicative of the voltage to be achieved at network terminals of the filter to control the switching devices of the second rectifier/inverter.

    Abstract: A load-aware load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to determine the particular server's own measured load; convert the particular server's own measured load to a corresponding own particular load category of a plurality of load categories; provide the particular server's own particular load category to other servers of the plurality of servers; obtain load category information from other servers of the plurality of servers; and maintain, as an indication of server load of each of the plurality of servers, the particular server's own particular load category and the load category information from the other servers.

    Abstract: A method for performing impedance measurements on a subject. The method includes, in a processing system, causing at least one electrical signal to be applied to the subject via first leads operatively connected to first electrodes provided on the subject, determining a first indication indicative of at least one first electrical signal measured via second leads operatively disconnected from second electrodes positioned on the subject, determining a second indication indicative of at least one second electrical signal measured via second leads operatively connected to second electrodes positioned on the subject, and determining from the indications and the at least one applied signal, at least one instantaneous impedance value.

    Abstract: A content delivery network has at least a first tier of servers. A content delivery method includes, at a first server in the first tier of servers, obtaining a request from a client for a resource. If the resource is available at the first server or at a peer of the first server, then the resource is served to the client from the first server. Otherwise, it is determined whether the resource is popular, and if the resource is determined to be popular, then the first server obtains the resource and the first server serves the resource to the client. If the resource is determined not to be popular, the client is directed to a second server, not in the first tier of servers, and the second server serves the resource to the client. The second server may be in a second tier of servers or it may be an origin server.
