Abstract: A system for emulating an over-the-air environment for testing a Frequency-modulated Continuous Wave (FMCW) light detection and ranging (LiDAR) unit under test (UUT). The system includes an optical lens system that receives an FMCW laser signal from the LiDAR UUT, and provides the signals to one or more optical fibers. A slope, chirp timing and intensity of the FMCW laser signal is determined using digital signal processing, and a modulation waveform is determined to emulate an over-the-air (OTA) environment based at least in part on the slope, chirp timing, and intensity. An in-phase quadrature phase (IQ) modulator modulates the FMCW laser signal using the modulation waveform and provides the modulated laser signal back through the optical lens system to the LiDAR UUT.

Abstract: Apparatus and methods for training a person in route management are based on a personal computer. The apparatus may be used for example to train a bus driver to follow a new or changed route. A data store stores data streams corresponding to different kinds of information of the route, including video of the route, audio data, sound data, GPS and time data, and vehicle engine management data. A VDU and loudspeaker are used as output devices to present the plurality of data streams to a user such that they are co-related to the route to be followed. Data streams corresponding to different route information are not combined in the data store, but comprise cross-referable data. The computer is programmed to present the first data stream and the further data stream in a co-related manner via the output devices and in dependence upon the cross-referable data.

Abstract: A route followed by a person is managed. A data store is configured to store data streams corresponding to different kinds of information of a route followed by a person. Data output means is operable to output the data streams to a user such that they are co-related to the route followed by the person. Data handling means is operable to provide the stored data streams to the data output means. The data streams correspond to different route information and can be cross referenced. The data handling means is operable to provide a first data stream and further data stream in a predetermined manner to the data output means and in dependence upon the cross-referable data such that the first and further data streams are output by the data output means in a substantially co-related manner.
