    Abstract: A controller for an electromechanical transducer is provided. The controller comprises driving means operable to actuate a mechanical output of the transducer; impedance cancelling means operable to at least partially cancel an electrical impedance of the transducer; and linearising means between an input of the controller and the driving means. The linearising means are operable to generate an output signal by modifying an input signal of the linearising means to compensate for nonlinear behaviour of the transducer. The linearising means are operable to receive one or more state signals indicative of one or more state variables of the transducer, the one or more state signals comprising a velocity signal indicative of a velocity of the mechanical output of the transducer.

    Abstract: A reconfigurable banquet table includes a table top, a plurality of retaining clips, and two or more base members. The table top bottom surface includes a plurality of pairs of openings. A corresponding plurality of retaining clips are secured thereat. Each retaining clip includes a first flange and a second flange extending from a plate. Each base member includes first and second legs connected a set distance apart. The first and second legs of each base member are received in one pair of the table top openings, and releasably secured therein by the corresponding retaining clips, with one side of each of the first and second legs engaged by the second flange of the respective retaining clip, to cause deflection of the second flange to provide suitable retaining forces. Easy removability of the base members permits interchangeability without requiring tools, for greater functional/aesthetic versatility, easier transport, and more compact storage.

    Abstract: The present invention provides a method of limiting the frequency of floods within a data network, the floods arising as a data frame is routed to an unknown destination, the method comprising the steps of: receiving on an ingress port a data frame intended for a destination station and containing a MAC address of that station; checking the destination MAC address with the contents of a MAC table; and thereby determining whether the data frame is to be routed, discarded or flooded to all ports except the ingress port; and respectively routing, discarding or flooding the data frame to all ports except the ingress port. The present invention further provides a method of populating a MAC table within an Ethernet network with entries relating a MAC station address to a port to which it is connected, the method comprising the steps of: receiving on an ingress port a data frame intended for a destination station and containing a MAC address of that station; checking the destination MAC address with the contents of a MAC table; and thereby determining whether the destination MAC address and ingress port are to be written to the MAC table and, if so writing the destination MAC address and ingress port to the MAC table; and flooding the data frame to all ports except the ingress port.

    Abstract: A self-locating mounting apparatus for holding objects such as sensors at specific positions on a subject's head includes a central mount constituted by a plurality of inextensible elements adapted to fit over the top of a subject's head. In addition, the mounting apparatus includes an adjustable circumferential band adapted to circle the subject's head and connect the central mount to inextensible side elements via sliding joints. A plurality of biasing elements provide a force for biasing sensor mounting units on the mounting apparatus against a subject's head, allowing for long-term sensing while minimizing interference forces on the mounting units. Advantageously, the mounting apparatus holds sensors within approximately 5 mm of their desired measurement positions over a range of subject head sizes.

    Abstract: An infrared imaging microscope, particularly of the type used to carry out FT-IR measurement, including a detector in the form of a relatively small detector array of individual detector elements. The outputs of the detector elements are fed in parallel to an electronic circuit for processing. The relatively small array allows the outputs to be processed without need for multiplexing thereby avoiding reduction in signal-to-noise. The detector array may substantially range from about 3 to about 100 detector elements, and is preferably in a range from about 16 to about 64 detector elements.
