Title: Systems and methods for preventing distortion due to supply-based modulation index changes in an audio playback system
Inventor: TEJASVI DAS
IPC: H03G3/30
Filed: 2016-01-12
Abstract: Some personal audio devices include a power amplifier for driving an audio output signal to headphones or speakers. Distortion in the audio playback circuit may be avoided by predicting distortion of the analog output signal based on the digital input signal and the supply voltage so that a gain can be applied to the digital input signal and/or the analog output signal. The playback circuit may comprise a controllable digital gain element 12, a delta-sigma DAC 14, a class-D modulator 15, a class-D output driver 16 with controllable gain and a low-pass filter 22. The predictor 20 may monitor the digital input signal, the supply voltage VDD, the DAC supply voltage VREF, the supply current of the modulator 15 or driver 16, the frequency of these currents and of VDD and VREF, and the load impedance. Distortion may be due to supply-based modulation index changes. Clipping due to inadequate voltage supply may be predicted if the supply voltage is falling and the signal amplitude is rising (figure 4). Signal amplitude may be reduced by decreasing gain in the digital part of the circuit or by reducing gain in the analogue part of the circuit.

Patent GB-2591521-A (GB)
Title: Improvements in and relating to a multi-access edge computing (MEC) network
Inventor: WALTER FEATHERSTONE
IPC: H04L29/08
Filed: 2020-02-03
Abstract: A method of operating a Multi-access Edge Computing (MEC) network comprises instantiating a first application in the MEC system when a first entity (e.g. Operational Support System, OSS) sends an application instantiation request to a second entity (e.g. a MEC Orchestrator, MEO), wherein the request comprises pre-emption information concerning the first application, the pre-emption information being used to pre-empt the first application in the future, if required, by changing its operational state or by removing it. The second entity may decide to pre-empt the first application in the event that a request to instantiate a second application is received and there are insufficient resources available in the MEC system, or if a conflict prohibits the first and second applications from running concurrently. If sufficient resources cannot be made available by pre-empting the first application then the second application may not be instantiated. An application instantiation request may have an expiry time and if it is not initially fulfilled then it may be re-assessed if the time has not elapsed. The invention addresses the problem of how to ensure desired applications are made available to subscribers at a particular MEC host location when the hosting environment is resource constrained.

Title: A security system
Inventor: MICHAEL JOHN SUMNER
IPC: H04L9/32
Filed: 2020-04-15
Abstract: A method and system to perform cryptographic operations such as signing transactions of digital assets using a cryptographic key. A client 170 generates a request to perform a cryptographic operation on client data associated with the request. The request is received at a data storage system 155/165 which retrieves an encrypted version of a cryptographic key associated with the client request. A cryptographic operation request comprising the data and the encrypted key is transmitted to a digital storage device 110 via an airgap 120, such as data diode 122, that implements a protocol break. The digital storage device decrypts the encrypted key using a master key and performs the requested cryptographic operation on the data using the decrypted key. The result of the cryptographic operation is then output via the air-gap. The digital storage device may be a hardware security module (HSM) kept within a secure storage facility 105 such as a vault or bunker. The advantage of the invention is that the cryptographic key can only be used when decrypted by the master key within the secure area. The decrypted key is not stored, nor does it ever leave the secure area.
