Title: A structure to absorb, dissipate and measure a force
Inventor: JASON LLOYD ROBERTS
IPC: G01L19/06
Filed: 2015-11-05
Abstract: A structure to absorb, dissipate and measure force, comprising a plurality of distinct layers including a first impact absorbing material 12 having an outer face facing the direction of expected impact and an inner face. An impact dissipating layer 13 is adjacent to the inner face of the first impact absorbing material and has a higher flexural rigidity than the first impact absorbing material. A second impact absorbing material has an outer face adjacent to the impact dissipating layer and an opposite inner face, and has a lower hardness than the impact dissipating layer. A pressure sensor 14 is arranged across the inner face of the second impact absorbing material, wherein an impact on the outer face of the first impact absorbing material is partially absorbed by that material, dissipated by the impact dissipating layer and further absorbed by the second impact absorbing material, with the remaining transmitted force being sensed by the pressure sensor. The pressure sensor may be in the form of a matrix array (fig.3A). The structure may comprise an inner fabric layer 11 and an outer fabric layer 10, and may be used in a wearable garment 1 with impact absorbing pads 2 suitable for sport.

Title: Wind noise reduction
Inventor: THOMAS IVAN HARVEY
IPC: H04S7/00
Filed: 2014-07-11
Abstract: A method of wind noise reduction. Left side and right side microphone signals are obtained. In a first stage wind noise reduction is applied to a first sub-band of one of the signals, below a spectral threshold NA. In a second stage the wind noise reduced first side signal, and the second side signal, are both split into a sub-band below a threshold NB less than NA. The sub-band of the first side signal is mixed with the sub-band of the second side signal to produce an aggregate third sub-band signal having reduced wind noise, which is recombined with the respective sub- bands above the threshold NB to produce output first and second side signals.

Title: Universal filtered multi-carrier systems and methods
Inventor: LEI ZHANG
IPC: H04L27/26
Filed: 2016-02-18
Abstract: Embodiments of the invention provide methods and apparatus for transmitting and receiving Universal Filtered Multi-Carrier (UFMC) signals. A multicarrier signal is generated by transforming a plurality of data symbols to be transmitted on a plurality of subcarrier frequencies within a sub-band into a time domain multicarrier signal, and filtering the time domain multicarrier signal using a sub-band filter. The method further comprises a step of adding samples to the time domain multicarrier signal before transmission by applying a cyclic prefix or zero padding, or further comprises a step of removing samples from the filtered time domain multicarrier signal before transmission by performing tail cutting. A method of processing a received multicarrier signal is also disclosed, comprising the steps of: obtaining a plurality of time domain samples of the multicarrier signal; adding a plurality of the samples from a first signal portion at the beginning of the multicarrier signal to a plurality of the samples from a second signal portion at the end of the multicarrier signal; converting the multicarrier signal from the time domain to the frequency domain; and equalizing the frequency-domain multicarrier signal to obtain estimated data symbols. In some embodiments, the equalizer takes into account transmitter imperfections such as a carrier frequency offset and timing offset.

Title: Behaviometric signature authentication system and method
Inventor: YOSSI AVNI
IPC: G06K9/00
Filed: 2013-03-14
Abstract: A set of sampled data points, associated with a different position along the signature are compared with a set of characterizing nodes in a pre-stored user profile.
