Filed: 2016-12-21
Abstract: A fluid control system comprising an apparatus 12 having a first 14 and second 15 fluid ports, first 16 and 17 second control lines and a valve arrangement 18 switchable between a first state in which the first fluid port is in fluid communication with the first control line and the second fluid port is in fluid communication with the second control line and a second state in which the second fluid port is in fluid communication with a pressurized line and the first fluid port is in fluid communication with a vent. The valve arrangement is switched by a control arrangement e.g. electrically, pneumatically or electrically 24 controlled pilot lines 20 and solenoid valve 26. The apparatus is configurable between first and second configurations responsive to pressure differentials between the first and second control lines and may be a valve, coupling or latch in a subsea landing string. Allows high relative pressure in either control line to drive the apparatus to a failsafe configuration.

Filed: 2019-04-02
Abstract: A system for handling electronic documents comprising an end-user device capable of operating a program that displays data and capable of receiving input data, a document with fields, or placeholders, for input data, and software capable of analysing pages of the document to identify the location of the input fields and recording their properties, and capable of rasterising the pages of the document to create a pixmap/raster image of each page. The page property records are accessed to create fields or controls that are overlaid upon the pixmap displayed on the end-user device. When the fields or controls have been modified by an end-user or data process, the document is updated with the modified data and a new rasterised image is created and communicated to the end-user device to display. When the new image is approved by an end-user, the new pixmap image is saved on a server or on the end-user device.

IPC: H04W4/70
Filed: 2019-07-31
Abstract: A network controller (1, fig 1) receives a data stream comprising a plurality of communications from an Internet of things (IoT) device 2. Each communication is analysed 304 to identify whether the communication is malicious. In response to identifying that a communication is malicious, a security policy 16 is selectively applied to the data stream containing communications generated by the IoT device identified as malicious. The security policy permits the IoT device to continue to receive other data streams that are not associated with the malicious communications. The policy may be applied to a node adjacent to the IoT device. Applying the security policy to the data stream may include applying the policy to an application sending the communication. Security policy may be dependent on user input, IoT characteristics or the communication identified as malicious. Policies may be an instruction to cease, throttle, redirect or envelope traffic, apply IPS, constrain the IoT device or stop an application of the IoT device. The IoT device may be a network enabled sensor, the remote controller may be a network orchestrator, and the node adjacent to the IoT device may be a gateway serving the IoT device.

Title: Roof cleaning apparatus
Inventor: Stephen Dunmore
IPC: E04D15/00
Filed: 2020-04-24
Abstract: A roof cleaning apparatus comprises a cleaning head 22 defining a fluid conduit, the fluid conduit configured to receive cleaning fluid from a cleaning fluid source flowing in a first flow direction, the conduit redirecting the fluid so as to flow in a second flow direction different to the first flow direction and thereafter to egress the cleaning head in a fluid egress direction.
