Abstract: A transportation system is provided. The system includes: a highway vehicle, a first set of highway points located along a path of the vehicle, a second set of highway points located along a traffic signal section, at least one RFID tag located at each of the first set and the second set of highway points, and at least one RFID tag reader located on the highway vehicle connected to a network. The at least one RFID tag located at the first set of highway points is configured to store dynamic and static characteristics of the highway vehicle as it passes the first set of highway points and the at least one RFID tag located at the second set of highway points is configured to store dynamic and static characteristics of the vehicle as it passes the second set of highway points.

Abstract: An air conditioning unit (2) comprises a main body (3) including an air inlet (24) and an air outlet (22), the main body (3) defining an airflow passage between the air inlet (24) and the air outlet (22). A fan (28) is disposed within the airflow passage and a thermal element (26) is disposed within the airflow passage upstream of the fan (28). The main body (3) has a front face exposed to a temperature controlled space (8), on which the air outlet is disposed, and the air inlet and thermal element are disposed around the periphery of the front face.

Abstract: A robust system processor comprising three parallel processors, each configured to process in parallel an input and emit an output; and a reconciler that compares the three outputs, determines whether at least two of the outputs are equal, and if so validates the majority output and communicates the validated output via a network to at least one other system processor.

Abstract: A train control system comprising a track switch controller; RFID tags located at first and second track switches coupled via a length of track that store characteristics of train sets as they pass the track switches, and RFID tag readers located on the train sets, connected to a network. The train sets write data to the RFID tags such that the data is read by RFID tag readers of subsequent trains; and the data stored in the RFID tags is overwritten with new data each time a train set passes by the RFID tags.

Abstract: A modular bridge is formed from a plurality of bridge modules. In one embodiment, the bridge includes: a first longitudinal compression member that is, in use, at an upper part of the bridge cross-section; a second longitudinal compression member that is, in use, at a lower part of the bridge cross-section; a structural lateral element for forming a deck of the bridge or for supporting deck elements of the bridge; a shear element for carrying a shear load; and a tension member applying a compressive force to one of the longitudinal compression members such that when in use the other of the longitudinal compression members forms a main compression element for the bridge and the tension member forms a main tension element for the bridge. The bridge modules form segments of the length of the bridge and each bridge module is of a one-piece construction.
