IPC: A61B5/16
Filed: 2017-11-03
Abstract: Handheld or wearable behaviour capture device 100 comprises physical interface, such as resiliently deformable pressure sensor or push button 101, receiving inputs from user 110 to bookmark events e.g. moods, thoughts, emotions, habits or cravings. User input patterns may include pressure and duration, or e.g. one short followed by one long squeeze, the device determining if input corresponds to such predetermined identifiers. Input not in accordance e.g. a ‘fidget’ action may be considered a non-bookmark event. Feedback is provided to the user, via LEDs, a display or haptic feedback motor. The device may also generate orientation and acceleration data, or include a GNSS receiver. Physiological sensors for e.g. skin response or pulse rate may also be stored, providing additional data to complement the bookmarked data. For example, stress indicated by skin readings or heart beat can be compared with times the user records a stress bookmark.

Title: Identifying processing units in a processor
Inventor: STEPHEN FELIX
IPC: G06F15/173
Filed: 2018-12-21
Abstract: A processor system has processing circuits 61 arranged in columns 62. Each processing circuit comprises one or more processing units or cores 4. The units are addressed using a column identifier, an identifier of the circuit within the column and an identifier of the unit within the circuit. To assign the circuit identifier, an identifier is assigned to the first unit in the column. This may default to zero. The circuit stores this identifier and increments its value by one. It then sends the incremented value to the next circuit in the column. This process is repeated until all the circuits have an identifier. If one of the circuits is defective, it does not store the address and passes it on unmodified. The circuit may detect that it is defective by comparing the its identifier with a repair code. Each column may have a unique repair code set using effuses.

Title: Amplified stimulated emission semiconductor source
Inventor: MARCUS DÜLK
IPC: H01S5/50
Filed: 2019-01-31
Abstract: An amplified stimulated emission, ASE, source device in which a superluminescent light emitting diode, SLED 15, is paired with a semiconductor optical amplifier, SOA 22, the SLED 15 and SOA 22 being arranged in series so that the SLED15 acts as a seed and the SOA 22 acts as a broadband amplifier for the light output from the SLED 15. Both SLED 15 and SOA 22 have a structure made up of a succession of epitaxial semiconductor layers which form an optical mode confining waveguide comprising a core of a higher refractive index, active region layer (10, Figure 2), and a cladding of lower refractive index, cladding layers. The combination of an SLED with SOA allows higher power outputs to be achieved than with an SLED source alone, because the power limits for the SLED imposed by the catastrophic optical damage threshold and the onset of non-linear effects caused by saturation can be circumvented. Alternatively, fundus or endoscopic imaging and projection systems may comprise the ASE source device.

Title: Low profile remote trigger for hydrostatically set borehole tools
Inventor: KEVEN O'CONNOR
IPC: E21B41/00
Filed: 2017-08-09
Abstract: A pin whose movement triggers setting of the borehole tool, is initially held by a collet that is supported off a surrounding housing. A spring is supported off the pin and would push a housing that locks the collet to the pin axially to unsupport the collet but for the presence of a Kevlar® wire that has an associated heater. The wire pulls the housing that locks the collet against the spring bias and has an end attached to the pin. Melting the wire allows the spring to move the housing that traps the collet to the pin. At that point hydrostatic pressure can move the pin to either open a port on the borehole tool to set it hydro statically or to move an actuation rod attached to the pin to set the borehole tool mechanically or with a combination of mechanical and hydraulic force.

Title: System and method for decentralized identity management, authentication and authorization of applications
Inventor: SHYAM KUMAR DODDAVULA
IPC: H04L9/32
Filed: 2019-09-27
Abstract: Applications 402/432 register public keys and permissions, via clients 404/434 (probably the device that the app runs on), with an authorisation service. The authorisation service is accessed through servers 408/438 and approves/records keys/permissions using a blockchain. The approval is made using the blockchain consensus algorithm 426/456 which based on a smart contract. Approved keys/permissions are stored in the nodes of the blockchain’s distributed ledger 414/416/422/424. A registered app may request an authorisation token from the authorisation service, the authorisation service and/or app may sign the token using their private keys. The token is included in a message requesting a service from provider app. The provider app retrieves the requester’s public key from the authorisation service and uses it to validate the token. If validation shows that the requester is authorised the service is provided.
