Title: Home concert system, method therefor and audio system
Inventor: JASON CHARLES REGLER
IPC: H04N21/431
Filed: 2021-01-21
Abstract: External speakers (70, 72) are addressed via the intermediately located splitter (50) which provides inter-operability between different vendor technology platforms, namely a media player (22) and the speakers (70, 72). Separating audio generation, via the splitter (50), and assigning processing to a remote speaker rather than at an effective source of a media file (10) permits content-synchronized audio triggers (12a-12j), such as tones, to be embedded on one of the channels of a ubiquitous stereo pair, whilst a full record of, for example, a music track (60) is supported on the other channel of the stereo pair. The audio triggers are extracted by the splitter (50), converted into control data that is onwardly communicated to control local visual effects on, for example, RF-controlled LED wristbands or discrete lighting units. In response to the control data, these lighting devices present a pre-programmed and coordinated lighting effect synchronized to instantaneous audio output from the speaker(s) and video images generated on the media player (22). The splitter (50) replicates the music track on a plurality of audio channels and communicates this information so that it can be broadcast from the speaker(s) that each receive the same music content but over different channels. The effect is a fully immersive interactive sensory concert experience at a remote location, with the splitter (50) making use of a ubiquitous and universally-accepted audio channel whilst ensuring that synchronized control tones do not bleed into the generated audio because the audio processing is separated at the splitter.

Title: Methods of manufacturing a moulded, formerless multi-coil cylindrical superconducting magnet structure, and a structure as may be manufactured by such methods
Inventor: SIMON JAMES CALVERT
IPC: H01F41/12
Filed: 2021-09-23
Abstract: A method for the manufacture of a formerless, multi-coil cylindrical superconducting magnet structure comprises providing temporary locating features 32 protruding from a radially outer surface 12 of a mandrel 10 defining axial sections 16, 18. Superconducting wire is wound into axial segments 16 to form superconducting coils (50, Figure 3).

The structure is removed from the moulding tool and the mandrel removed, which preferably causes the temporary locating features to shear at a shear plane. The temporary locating features may comprise tabs 32 or pins (110, Figure 8) of friable material inserted into recesses 30 or holes (112, Figure 8) in the mandrel. Ends of superconducting wires (76, Figure 6) may be led out in cavities formed within a wall of the moulding tool and retained in a resin block monolithically formed with the resin-impregnated magnet structure. A superconducting magnet structure (78, Figure 6) manufactured by the method is also provided.

Title: Transaction key generation
Inventor: IAN DAVID ALAN MADDOCKS
IPC: H04L9/08
Filed: 2021-10-29
Abstract: Technical challenges arise in providing financial transaction services to large numbers of clients, particularly in maintenance and storage of master keys as the number of keys increases. According to the invention, the issuer master keys (IMK) for a particular issuer may be derived from the system level key in conjunction with issuer derivation data that is received either during a transaction of a payment device (card) or as part of provisioning a payment device into a digital wallet. The cryptographic keys (e.g. issuer master key, card master keys and session keys) form a hierarchical structure with the system level key at the top (above the issuer master keys). Therefore, the transaction system avoids the need to store issuer master keys for each issuer. Instead, the transaction system may comprise a digital enablement system having a key management system being arranged to store the system level key and derive issuer master keys on the fly from the stored system level key using the issuer derivation data. The disclosure also provides methods of authenticating payment or digitising payment devices or cards for use in individual transactions and to provision credentials onto payment devices (physical cards or digital wallets/digital cards).

Abstract: A cryogenic adsorption refrigerator 100 for cooling a thermal load (200, fig 2A) comprises an adsorption pump 101 having a chamber 104 containing an adsorbent material 105, an evaporator 102 arranged to contain liquid coolant (201), and one or more fluid flow conduits 103a, 103b.The evaporator comprises a first 106 and second 107 evaporation chamber, with the first chamber fluidly connected with the pump via the conduit(s) whereby gaseous coolant flows from the first chamber to the pump. The first and second chambers are fluidly connected via a flow control aperture 109 that reduces the flow of superfluid coolant (202, fig 2B) from the second to the first chamber. The reduction in superfluid coolant flow increases cooling time of the evaporator. A wall / plate 108 within the evaporator may separate the chambers and the aperture may be located therein. The aperture may be tapered (fig 3), may comprise an electropolished or atomically sharp knife edge, and in use may be located to not be vertically aligned with the conduit(s). The adsorbent may be activated charcoal or mineral zeolite and heating of the pump regenerates the coolant by desorbing from the adsorbent and condenses on a plate (203, fig 2E).
