Title: Provision of bi-directional signals via fibre optic data distribution system
Inventor: GARY STAFFORD
IPC: H04N21/61
Filed: 2016-03-21
Abstract: A distribution system including a fibre optic cable network allows the distribution of broadcast video and/or audio data received by apparatus 2, 12 at a receiving location to apparatus at one or more user (e.g. set-top box, STB) locations 4. Transmission of command (control) data signals 24 through the distribution system (e.g. two-way, opposite direction, return path) in an optical format to apparatus at the user and receiving locations allows the control and change of operation of selected apparatus connected to the distribution system. Typically the command signal data is transmitted at a different, e.g. lower, frequency (e.g. 20-25 KHz) than video and/or audio data. Relevance of the command signal to a particular apparatus may be based on identification (ID) code, e.g. a serial number. The system may apply command signals in Digital Satellite Equipment Control (DiSEqC) format to an optical fibre network.

Title: Non-isotropic accoustic cable design
Inventor: DANIEL FINFER
IPC: G01H9/00
Filed: 2013-09-13
Abstract: A fibre optic cable 20 has non-isotropic acoustic sensitivity for directional acoustic sensing. The cable further comprises discrete sensing regions along its length for localised spatial sensing. The discrete sensing regions are realised by the cable having an acoustic insulating layer 201 between an optical fibre arrangement 100, e.g., a fibre-in-metal-tube (FIMT), and an outer jacket layer 101 of the cable, wherein acoustic coupling regions are interspersed along the fibre for transmitting acoustic energy from the outer layer to the optical fibre. The coupling regions may comprise a filler material 202 inserted into the acoustic insulating layer to bridge the outer layer and fibre. Alternatively, the outer layer may be narrowed or crimped at points along the cable to bring it close to or into contact with the fibre. The fibre optic cable may be used in a distributed acoustic sensing (DAS) system and the locations of the acoustic coupling regions may be tailored to match the resolution of the distributed sensing system.

Title: Monitoring of distributed systems
Inventor: Paul McKee
IPC: G05D23/19
Filed: 2018-02-02
Abstract: A network of sensors (e.g. temperature gauges) and actuators (e.g. air conditioning units) is operated in accordance with predetermined policies, and the effectiveness of individual policies is monitored by comparing inputs from the sensors 550 with intended outcomes from policies controlled by previous inputs from one or more of the same sensors. Each policy includes a check function 554 , wherein a sensor, other than the one that triggers the actions, monitors the actions generated by the policy and generates an output 556 indicative of whether a system state is approaching a condition specified by the policy. Actions generated by the policy may be initiated in response to inputs from first sensors, and the check function initiated based on independent further sensors 554. The check function may be initiated after a predetermined period to allow the system to stabilise. A policy quality ranking may be generated based on the policy effectiveness, the implementation of the policy controlled based on its quality. Policies with a low quality ranking may be alerted to a user interface when triggered. A semantic context broker function may monitor performance of policies triggered by a common sensor to generate a reliability value for the sensor.

Title: Reader for medical implants
Inventor: SHILEI LANG
IPC: H03F3/45
Filed: 2019-01-10
Abstract: A RFID tag reader suitable for reading medical implants. The transceiver chip 10 comprises a power amplifier 11, a resistor 12 and a signal processing module 13. The interference of the interrogation signal and RFID tag response signal on the antenna causes the load demanded by the power amplifier to change. The load change is detected at reference point V0 by the signal processing unit 13 which filters the signal and sends it to an external electronic device through the signal output port OUT2. Thus, interference between the first interrogation and response signals can be avoided. The power amplifier may comprise input ports Vin1, Vin2, output ports Out11, Out12. The output ports may be connected to the antenna through an impedance matching network (20, Fig. 1). The power amplifier may comprise a symmetric inductor structure (L1, L2, L3, Fig. 3), a capacitor arrangement (C1, C2, C3, Fig. 3) and a first (111, Fig. 3) and second (112, Fig. 3) amplifying module.
