Title: Free space optical communications terminal
Inventor: Crisanto Quintana Sanchez
IPC: H04J14/06
Filed: 2020-10-29
Abstract: A free space optical communications transmitter terminal 102 comprises a first optical source 204, which emits a classical first beam of light 214, and a second optical source 206, which emits photons 216. The classical beam encodes information to be communicated and the photons encode bits of a key of a Quantum Key Distribution (QKD) protocol. The classical first beam and the photons are each linearly polarised. An optical arrangement 208 combines the first beam and the photons into a single, second beam 218’ to be transmitted to a receiver terminal. The optical arrangement also transforms the linear polarisations to circular polarisations such that classical and QKD components of the second beam are circularly polarised, with opposite handedness. A receiver terminal receives the second beam, transforms the circular polarisations into orthogonal linear polarisations, and filters out the linear polarisation of the first beam to allow the photons to pass to a single photon detector.

Title: Method for controlling a display
Inventor: Ramon Sadornil
IPC: G06F1/3231
Filed: 2020-12-22
Abstract: An apparatus that uses sensor data to detect an activity type of a user (user context) and an activity change and in response activates a display. Detecting the change may involve comparing a measurement to a specific reference value (threshold). The apparatus may deactivate or hibernate the display in response to detecting a second change. The activity type may be a sport, daily use or sleeping. Sensor data may involve acceleration, velocity, distance, tilt, ambient light, heart rate and location. For example, the device may activate the display if it detects that a user is swimming, cycling etc and the swimming velocity drops below a threshold and the device may deactivate the display if it detects that the swimming velocity rises above a threshold. The activity change may be based on activity rules selected by the user or it may be pre-learned, for example, if the same behaviour has repeated e.g. 3 times, the system may learn that the display is to be activated in those circumstances. In this way, the power consumption of the display battery may be reduced because the display is not activated in vain.

Title: System and method for group key formation
Inventor: DAVID WILLIAMS
IPC: H04L9/08
Filed: 2021-01-13
Abstract: A group key for a group of N parties, at least N-1 of which are in an ordered ring, is created using an intermediary. When the Nth party is in the ring, it is configured to share a cryptographic key of the party with an adjacent party in the ring, generate a meeting key for the party based on combining the cryptographic key of the party with a shared cryptographic key from an adjacent party, and send the meeting key to the intermediary and receive an intermediate key from the intermediary. The intermediary computes the intermediate key based on combining two or more meeting keys of corresponding parties in the ring. The group key is then based on combining the cryptographic key of the party with the received intermediate key. When the party is not in the ring, it shares a cryptographic key of an adjacent party in the ring with the rest of the party, receives the intermediate key of the adjacent party in the ring from the intermediary, and creates the group key based on combining the shared cryptographic key of the adjacent party with the received intermediate key.
