Abstract: Apparatus for performing impedance measurements on a subject. The apparatus includes a first processing system for determining an impedance measurement procedure and determining instructions corresponding to the measurement procedure. A second processing system is provided for receiving the instructions, using the instructions to generate control signals, with the control signals being used to apply one or more signals to the subject. The second processing system then receives first data indicative of the one or more signals applied to the subject, second data indicative of one or more signals measured across the subject and performs at least preliminary processing of the first and second data to thereby allow impedance values to be determined.

Abstract: A heavy haul vehicle has a chassis capable of supporting a load to be transported by the vehicle. A first group of one or more first drive axles and a second group of one or more second drive axles are coupled to the chassis. The vehicle also has a first engine and a second engine. The first engine drives each axle in the first group of drive axles. The second engine drives each axle in the second group drive axles.

Abstract: There is disclosed an apparatus for displacing earth, comprising: a driver-operable powered vehicle at a forward position of the apparatus; one or more ground-displacing units coupled to the vehicle to be pulled thereby, the or each ground-displacing unit including a ground-engageable implement; and a powered dolly coupled to the unit(s) so as to provide to the apparatus locomotion which supplements that provided by the vehicle.

Abstract: A double articulated truck has a front vehicle module with a drive engine and having at least one wheeled axle driven by the drive engine through a transmission and having a load-bearing bin, the front vehicle module being interconnected in an articulated manner about a first vertical pin to the front of the load-bearing bin. A rear vehicle module is interconnected in an articulated manner about a second vertical pin to the rear of the load-bearing bin, the rear vehicle module having at least one wheeled axle whereby the bin is supported by the front and rear vehicle modules. The rear module only articulates about the second vertical pin when the articulation of the front module to the bin exceeds 30 degrees and then in a synchronous manner. Typically the maximum articulation of the front module is around 42 degrees and the rear module some 13 degrees.

Abstract: In systems and methods for freezing and subsequently thawing liquid samples containing biological components, a sample is fractioned into a very large number of small drops (10) having surface area to volume ratios of 1000 m-1 or greater. The drops are projected at a liquid cryogen (40) or at the solid surface of a highly thermally conducting metal cup or plate, where they rapidly freeze. The cold gas layer that develops above any cold surface is replaced with a dry gas stream (75). The environmental temperature experienced by the sample then abruptly changes from the warm ambient to the temperature of the cryogenic liquid or solid surface. To thaw drops with the highest warming rates, the frozen drops may be projected into warm liquids. The sample is projected with cold gas to the warm liquid, so that again there is an abrupt transition in the environmental temperature.
