Title: Method of manufacturing a microstructure
Inventor: ANTHONY O'HARA
IPC: H01L21/02
Filed: 2019-11-14
Abstract: Method of manufacturing a microstructure (e.g. MEMS) comprises employing a hydrogen fluoride (HF) vapour to etch a sacrificial layer of silicon dioxide (SiO2) and removing a residue or residual layer formed in said etch, wherein the residual layer comprises silicon (Si), carbon (C) or ammonium Salt (NH4). When the residual layer comprises silicon, removing the residual layer may comprise reacting the silicon with a fluorine gas to produce silicon tetrafluoride (SiF4). When the residual layer comprises carbon, removing the residual layer may comprise reacting the carbon with either oxygen gas to produce carbon dioxide (CO2) / carbon monoxide (CO) or a hydrogen gas to produce methane (CHO). When the residual layer comprises ammonium salt, removing the residual layer may comprise heating the ammonium salt to a temperature greater than 160C. This may increase the volatility of the residual layer so that it can be removed using a vacuum pumping system.

IPC: H04W74/08
Filed: 2021-06-18
Abstract: In a communication network, a node transmits a given type of traffic during a dedicated service period allocated by the access point. At the end of the service period, following successful transmission, the node switches to a second contention parameter set. The given type of traffic may be low latency traffic, and the dedicated service period may be a Target Wait Time (TWT) service period.

Title: A radiotherapy apparatus
Inventor: CLIFF PERKINS
IPC: A61N5/10
Filed: 2021-12-06
Abstract: Radiotherapy apparatus comprising a gantry rotatable about a gantry rotation axis and supported by a plurality of rotatable rollers positioned underneath the gantry. At least one roller 614A is rotatable about an axle 650. The axle 650 rotates about an axle rotation axis. When the axle 650 rotates it displaces the rotatable roller 614A perpendicular to the gantry rotation axis; the roller rotates laterally relative to the gantry’s rotation axis. An eccentric section 651 of the axle 650 has a larger radius with an axis offset relative to the axle’s axis. The axle can be rotated by a hexagonal axle nut cap 654. On installing the radiotherapy apparatus the impact of gravity and other forces on the isocentre of the gantry can be determined. Pairs of rollers (514A, 514B, figures 3A-D) can be laterally moved by the offset eccentric axles to move the gantry and compensate for any corkscrew effect (fig 2B).

Title: Monitoring optical access networks
Inventor: IAN COOPER
IPC: H04L41/044
Filed: 2022-03-24
Abstract: A method and apparatus to monitor an optical access network. An optical head-end 1400 provides network access to customer premises equipment (CPE) 1200. The optical head-end contains a data processing system (DPS) 1100 which receives telemetry data from the CPE on an on-going basis and stores it in local storage 1120. The DPS determines from the telemetry data whether a trigger condition has been met, and if so, a report is transmitted to a support system 1300. The trigger condition may be determined by expert system analysis, pattern matching or a neural network. The telemetry data may indicate: Forward Error Correction (FEC) statistics, dropped packet statistics, queue lengths, optical power measurements, device temperature measurements etc. The advantage of the invention is that continuous telemetry analysis such as that required by Central Office Re-architected as a Datacentre (CORD) technology may be achieved without overwhelming the communication network with telemetry data. By decentralising the analysis of telemetry, management traffic overheads may be reduced and network resources expended on unnecessary reporting, such as power, bandwidth etc., may be decreased.

Title: Methods for operating battery frequency response
Inventor: NATHAN MESSER
IPC: H02J3/32
Filed: 2022-03-24
Abstract: A battery is operated to provide frequency response to a power grid. The battery has a plurality of containers, each configured to store electrical energy. A container target response is determined for a given container by dividing the system target response by the plurality of containers, and a container capacity is determined by dividing the battery capacity by the plurality of containers. Astate-of-charge offset is determined as the difference between the average state of charge across the plurality of containers and a state of charge of the given container. A response adjustment is determined by multiplying the container capacity by the state-of-charge offset, and a response for the given container is determined by adjusting the container target response by the response adjustment. This method allows the battery to be operated efficiently even when different containers in the battery diverge. The method may also take account of failed containers by adjusting the system target response accordingly.
