Abstract: An implement, such as a header for a combine, having an integral transport system with a pair of ground engaging wheels that are moved between transport positions used in transporting the implement and stowed positions on the implement during use of the implement. The wheels may be used as gauge wheels during use to support the ends of the implement. A trailer tongue is retractable and stowed onboard the implement during use, as is a tongue jack. Lights are provided at the end of the implement for visibility during transport. The lights are stowed beneath a cover on the end of the implement to protect the lights from damage during use. All components of the transport system are carried on the implement during use to ensure that they are with the implement when needed to transport the implement. All components are mounted with pins, enabling the implement to be converted between transport and use configurations without the use of hand tools.

Abstract: A network communication and messaging protocol for use in a medical perfusion system, provides the rules which govern how, among other things, information and data is conveyed between the various devices which are connect to the network. The rules define the different types of messages that are used in conveying information and data, as well as the formatting for each of those message types. The various messages provide the ability to configure the perfusion system devices, establish links between the perfusion system devices, and convey various types of information and data, even when the main network controller is unavailable.

Abstract: Optical assemblies of the type supported on an optical bench and comprising a one or more components such as lasers, lenses, filters, isolators and waveguides, are sensitive to movement variation. One of the causes of movement is temperature tracking. Previously, thermo-electric coolers have been used to maintain the top-surface temperature of an optical bench within a certain range. However, although thermo-electric coolers are operable to maintain optical bench temperature they are themselves still sensitive to temperature tracking and can deform. Because an optical bench is typically supported on the top surface of a thermo-electric cooler this leads to deformation of the optical bench itself and as a result performance of the optical assembly is affected. An improved design of thermo-electric cooler is described where the top surface of the cooler is divided into separate regions, each having a neutral region in which deformation is minimal.
