A data transmission and compression method arranged to compress and transmit data between an edge device and a remote server. The method includes collecting data at the edge device, wherein the data is attributed to a plurality of signal signatures, generating a data matrix at the edge device, and transforming the data matrix, wherein transforming the data includes using a wavelet transform. The method further includes compressing the data, wherein compressing the data includes utilising an autoencoder, and transmitting the encoded compressed data to the remote server via a communication channel. The method further includes, at the remote server, decompressing the data utilising an autoencoder, reconstructing the signal signatures using an inverse wavelet transform, and storing the reconstructed data signatures in a datastore on the remote server.

Compression of multimodal sensed signals

A message ID decoding method is provided for a system comprising multiple components interlinked by a Controller Area Network bus (CAN-bus) through which messages are sent. The method includes acquiring a CAN-bus message data stream including multiple CAN-bus messages, each including a CAN ID indicating a component from which the corresponding CAN-bus message originated; storing the CAN-bus messages in a first datastore; acquiring an electricity consumption signal indicative of the consumption of the component; storing the electricity consumption signal in a second datastore; generating multiple time-stamp bins each corresponding to an interval in time; selecting the CAN ID and a portion of the electricity consumption signal being from the interval in time corresponding to the time-stamp bin; and determining a regression coefficient, R, indicating a level of relatedness between the selected CAN ID and portion, thereby correlating the CAN ID of the selected CAN-bus message with the component.

Message ID decoding method

A method for compressing a signal, the method comprising: acquiring, via a signal recording module, a primary signal; modelling, via a processor, a model signal of the primary signal by: acquiring, via the processor, a sampled signal; acquiring, via the processor, a windowed signal; and extracting, via the processor: a fundamental frequency waveform having a fundamental magnitude and a fundamental phase; and at least one harmonic frequency waveform having a harmonic magnitude and a harmonic phase; wherein the model signal comprises the fundamental frequency waveform and the at least one harmonic frequency waveform; calculating, via the processor, an error signal between a reconstructed signal and the primary signal; determining, via the processor, an optimal gain from at least; an averaging step providing an average value, a predefined threshold, and a scaled signal.

Efficient codec for electrical signals

A method characterizes a noise event, and includes locating microphones in an environment and generating a training event at a location in the environment as a reference for a noise event. A sound sample is recorded at each microphone and phase differences between the sound samples are used to establish a noise event signature for an event at that location. A noise event may subsequently be identified by taking sound samples from the microphones associated with the noise event and using phase differences between them to identify the noise event by matching against noise event signatures.
