Title: Multimedia system & method
Inventor: Guy Piers O'Hanlon
IPC: H04L29/06
Filed: 2019-11-14
Abstract: A client receiving live-streamed media at low latency is unable to determine whether a channel used for the streaming is able to support higher data rates which would enable receipt of higher quality streams. In one aspect of the invention, the client measures the average received data rate over a plurality of intervals, ignoring intervals with zero received data i.e. intervals corresponding to chunk creation at a streaming source. In a second aspect the client receives data relating to TCP properties, such as congestion window and round trip time (RTT), in HTTP headers or trailers sent e.g. by a content server in response to GET requests from the client. The client can then determine an available bandwidth of the link using one or both of these aspects, and thus determine whether to request streaming at a higher data rate.

Title: Spiking synaptic elements for spiking neural networks
Inventor: ANGELIKI PANTAZI
IPC: G06N3/08
Filed: 2020-02-27
Abstract: A method is directed to transmitting signals between neurons of a hardware-implemented, spiking neural network (or SNN). The network includes neuronal connections, each including a synaptic unit connecting a pre-synaptic neuron to a post-synaptic neuron. Spikes received from the pre-synaptic neuron of said each neuronal connection are first modulated, in frequency, based on a synaptic weight stored on said each synaptic unit, to generate post-synaptic spikes, such that a first number of spikes received from the pre-synaptic neuron are translated into a second number of post-synaptic spikes. At least some of the spikes received from the pre-synaptic neuron may, each, be translated into a train of two or more post-synaptic spikes. The post-synaptic spikes generated are subsequently transmitted to the post-synaptic neuron of said each neuronal connection. The method makes it possible to obtain a higher dynamic range in the synapse output.

Title: Apparatus to monitor mental attention
Inventor: Mathew Norbury
IPC: A61B5/00
Filed: 2022-04-11
Abstract: A system 10 comprises a wearable device 20 having a sensor array (210, fig.2) to collect biometric data by functional near-infrared spectroscopy (fNIRS) and apparatus 30 with processing circuitry (320, fig.3) to analyse the biometric data to obtain a mental attention metric, which may include haemodynamic information of a pre-frontal cortex for comparison to a threshold defining a predetermined mental attention level. Analysis may be based on a modified Beer-Lambert law and may include classification using a trained classifier. Based on the comparison, a signal indicative of the mental attention level of the user is output. The signal may indicate that mental attention of the user is low and perhaps unsafe and may be a visual, haptic or audio indication. The system 20 may comprise a motion sensor to obtain motion data, which may be used to compensate for poor quality light absorption data. The apparatus 30 may be integrated with the wearable device 20. Biometric data may be encrypted and may be stored in a database (330, fig.3) to be retrieved and analysed to determine a trend of the mental attention of the user.
