Title: System and method for maintaining power source
Inventor: COLIN JOHN HALSEY
IPC: H02J7/00
Filed: 2018-10-01
Abstract: A system 58 for maintaining a power source 60 has a series stack of power storage devices 62 and a controller module 90. The power storage devices 62 can be selectively enabled to provide a summated output 64. The controller module 90 selects a power storage device 62 from the stack and enables it to discharge its stored power by activating voltage connection 80 until its sensed voltage reaches a minimum threshold. The power storage device 62 is then disabled by activating bypass 84 and a recharging power (92, figure 4) is applied until the sensed voltage indicates full charge. The state of charge data or capacity data of the selected power storage device 62 is then reset. Each power storage device 62 of the stack can be sequentially maintained in this fashion, thus preventing the state of charge or capacity data from drifting away from its true value without bringing the power source 60 out of operation.

Patent GB-2591731-A (GB)
Title: Elimination of microphone feedback using cardioid antennas
Inventor: ADRIAN GIBBY
IPC: H04R3/02
Filed: 2019-12-11
Abstract: Current anti-feedback systems detect feedback and suppress this by either changing the frequency response, adding a phase shift or changing the frequency of the audio. This enables the system to achieve a higher loop gain giving a higher output for the loudspeaker. This system differs from this by determining the maximum loop gain before feedback in a setup phase. The loop gain of each microphone combination is limited below this level. So, this system does not increase the maximum output but limits it below a predetermined level. This system calculates the loop gain by determining the effective audio path length of each microphone in respect to each loudspeaker in real time by measuring the RF signal strength as received at the loudspeaker from the microphone, as well as gain and frequency response of the system. This system can be used in conjunction with existing anti-feedback systems that enable a higher output from the loudspeaker.
