Title: Methods, apparatus and systems for biometric processes
Inventor: THOMAS IVAN HARVEY
IPC: G06F21/32
Filed: 2019-06-19
Abstract: Disclosed is an ear canal biometric authentication method 500. The method starts by generating an acoustic stimulus 502 to be applied to a user's ear. Then a quality measure of the response signal is determined 504. If the quality measure is inadequate for performing the biometric authentication process, then a property of the acoustic stimulus is modified to improve a signal to noise ratio, SNR, of the response signal 506. The acoustic stimulus may be modified by changing the gain, increasing the duration, applying an additional signal, shifting the pitch of the acoustic stimulus, applying masking noise, amplifying ambient noise and/or the user’s voice via hear through mode or sidetone path, using a masking model to add inaudible or harmonic content to the acoustic stimulus. The method may cancel the effect of noise from outside of the ear on the response signal of the user's ear to the acoustic stimulus to improve the SNR of the response signal.

Title: Improved device and method for demodulating information
Inventor: NIGEL JAMES TOLSON
IPC: H04L27/38
Filed: 2019-11-05
Abstract: The invention is for use on a modulated communication signal which comprises source data mapped onto a first modulation scheme providing a first set of complex symbols and at least one further modulation scheme providing a further set of complex symbols. If phase rotation (or cycle slipping) occurs during a forward error correction (FEC) block, the whole block of data may be lost. The invention provides demodulation that allows increasing the FEC block size whilst monitoring and correcting for slowly changing phase rotation errors. The received signal 13 is split 23 into two processing routes. On the first route, the signal is de-spread using module 15 and integrated at integrator 17. The Arctan2 of the signal is obtained 18, providing a symbol output. This is forwarded to 1 to n Look Up Tables’s 29, 29a, 29b which have been adjusted e.g. each LUT is set to 360/n angles. This ensures that each LUT measures the quality of the fit of the input angles. The same is carried out along the second route. Circuit 30 evaluates all of the fit values from the LUT’s and selects the symbol stream from that LUT as the output data stream.

Patent GB-2593977-A (GB)
Title: An umbilical cord clamp
Inventor: RALPH PAUL DAY
IPC: A61B17/122
Filed: 2021-03-10
Abstract: An umbilical cord clamp includes a pair of tapered jaw beams 5 (or arms) connected by a hinge 1. The hinge 1 is flexible, directly connecting the clamp arms such that little or no distance exists between them when the clamp is open. As there is no C-loop or accompanying hinge gate at the hinge, the umbilical cord is less likely to get trapped or punctured. The tapered clamp arms are preferably arranged to undergo proportional deflection along two-thirds their length from the hinge. This allows the clamp to apply a uniform force across an umbilical cord and accommodate a range of umbilical cord diameters. An irreversible locking latch 3 may be provided to hold the jaws arms 5 closed. Ideally, a viewing aperture 6 and a click provide visual and audible confirmation of clamp closure. A soft elastomeric surface may be moulded over the clamp to round-off angular edges and to enhance grip.
