Inventor: MANUEL SCHIER
IPC: G06K9/00
Filed: 2020-03-05
Abstract: A method and system for determining visibility regions of different object types for an autonomous vehicle. The system receives 302 sensor inputs of dimensions of a visibility region from sensors of various sensor types associated with the autonomous vehicle. The system generates 304 customized visibility regions for each sensor at various time frames, for obstacles of at least one object type, using the sensor input of corresponding sensor. Further, the system determines 306 a unified visibility region of each sensor type, for the obstacle of each object type, using the customized visibility regions of the sensors of corresponding sensor type for corresponding object type. The system identifies 308 an intersecting visibility region for each object type using the unified visibility region of various sensor types and may determine 310 a likelihood of non-existence of obstacles of specific object type in each intersecting visibility region.

Patent GB-2597333-A (GB)
Title: Key exchange protocol
Inventor: DARYL SCOTT BURNS
IPC: H04L9/08
Filed: 2020-07-20
Abstract: Method, apparatus and system for secure communications between devices. A message to be sent by a sender device is encrypted or encapsulated using post-quantum cryptography, 202, e.g. a Bit-Flipping Key Encapsulation (BIKE) algorithm. The message is further encrypted using quantum key material (QK), 204, e,g. a QK one-time pad, which has been derived from QK distribution (QKD) with a receiver device. Noise is added to the message and it is transmitted to the receiver, 206. Upon receipt of the noisy message, the receiver device decrypts or decapsulates it using the QKD material. The noise which was added is then removed and the post-quantum cryptographic algorithm used to decrypt or decapsulate the message to its original form for output. The message sent may be a cryptographic key required to be exchanged between the two parties. The advantage of the hybrid process used is that the noise removal procedure is inverted, which is made possible by the nature of BIKE and its compatibility with one-time pad encryption using QKD-sourced material. This means that even if an attacker were able to break the BIKE encryption/encapsulation), leveraging this ability would not be possible without breaking the QKD one-time pad encryption first.

Title: Digital Information Exchange
Inventor: RICHARD LAWSON
IPC: G06Q50/18
Filed: 2021-01-20
Abstract: An efficient method and platform which seeks to improve information exchange, for example during class actions, between potential clients and financial and legal firms that could act on their behalf. Law firms may be raked for selection according to a score based on fees and win to loss ratio. Client long securities data and court legal data could be cross-referenced to identify matches and notify potential claimants. A lead plaintiff in a class action may be determined by creating data records including the position and loss of plaintiffs, determining which plaintiffs are eligible and creating a list of them, setting the plaintiff with the largest loss as the lead plaintiff in the class action, and sending details of the lead plaintiff to a third party. Unrealised losses may be calculated by comparing account positions with court data to find matches and then marking market prices at the time of a key event, using post event corporate data, calculating unrealised loss, and outputting unrealised loss by account. There are also methods of receiving funding for, and settling, class actions.
