Abstract: A planar transformer includes a plurality of conductor plates each having a channel or groove to form first and second portions and the equivalent of a single wire turn. Insulator sheets 94 are stacked between conductor windings with windows or apertures for connection between plates to form packets 28, 30, 32, 34, 36. Terminal, tab and common plates, which may be made of copper sheets, may facilitate connection within packets and between primary and secondary packets with an ordering of tab, common, common then terminal plates, with insulating sheets 94 between them. The packets may be stacked in alternating order with a magnetic core 100a 100b running through a central window or aperture thereby utilising electromagnetic induction. The packets may be primary or secondary sides and connected to other primary or secondary packets using the terminal conductor plates.

Title: Process plant network with secured external access
Inventor: LEE A NEITZEL
IPC: H04L29/08
Filed: 2015-11-13
Abstract: A process control system having a data server 200 that provides process control data to external networks via one or more firewalls (108, Fig. 1) implements a security mechanism that reduces/eliminates the ability of the data server, and the process control system, to be compromised by viruses or other security attacks. The security mechanism includes a DMZ gateway 206 disposed outside of the process control network that connects to a data server located within the process control network. A configuration engine 215, located within the process control network, configures the data server to publish preset/pre-established data views to the DMZ gateway, which then receives the data/events/alarms as defined by the data views from the control system automatically, without performing read and write requests to the external data server. The DMZ gateway republishes the data within the data views externally to make the process control data within the published data views available to external client applications 210. Because this security mechanism does not support client read, write, or configuration access to the data server within the control system, this security mechanism acts to isolate the process control network from external attacks or viruses. The data server may be an OPC server.

Title: A method to encode video with close multiple scene changes
Inventor: WEI ZHOU
IPC: H04N19/87
Filed: 2015-12-16
Abstract: A method for encoding video with at least two close scene changes, where scene change frames are detected. If the first and second scene change frames are greater than a threshold number of frames apart then the scene changes are encoded normally but if the scene change frames are less than the threshold number of frames apart then the significances of the first and second scene change are compared to a threshold and the changes that are higher than the threshold are encoded. Also claimed is a method and apparatus where when the first and second scene occur below the threshold number of steps, then the complexity of each of the scenes is determined and the absolute difference in complexity between consecutive scenes are compared to thresholds. If the difference between the first and second scene is above a first complexity threshold and the difference between the second and third scene is below a second complexity threshold then the first scene change frame is encoded with an I frame but using a quantisation parameter based on the blended complexity of the second and third scenes.

Title: Reactance measurement
Inventor: KAMALJIT SINGH CHANA
IPC: G01R27/02
Filed: 2016-01-18
Abstract: A method and apparatus for measuring reactance of a sensor, such as a coil 4 used for e.g. eddy current proximity measurements, for example between blade tips and casing in a jet engine or other turbo-machine, by measuring the phase of a signal dependent on the reactance of the sensing component, possibly a capacitor. Source 2 drives alternating current, possibly via a unit having fixed reactance 6A, 6B (possibly inductors 16, 18 & capacitances 20, 22) through the sensor 4. A measure of reactance is output 10 based upon a phase measurement possibly using a phase-locked loop (PLL) situated at output unit 30, which converts the phase difference between signals 41, 42 into an analogue voltage proportional to the measured phase. A temperature measurement e.g. by monitoring the resistance of the sensor 4 if a coil, may provide for a temperature corrected measure of reactance.

Title: Secure authentication mechanism using quick response codes
Inventor: Saravanan Sadacharam
IPC: H04L29/06
Filed: 2016-01-22
Abstract: The application is directed to improvements in security of electronic transactions using the question-response type method of verifying identity. Securing identification of a users identity is done using an authentication program which: receives an initiation of a transaction from a user, searches for associated information of the user, chooses an authentication query requiring input from the user based on the associated information, generating a visual code representing the authentication query e.g. a QR code, splitting the visual code into pieces and sending each piece of visual code to the user via a separate communication channel. Also disclosed is a means for receiving said code pieces and reassembling them to provide an authentication query to a user. The user response to the query may also be in the form of a visual code that is decoded by the invention and compared to information associated with the user to authenticate them.

The processing circuitry is arranged, when the capability state indicates the default state, to operate in the capability domain. However, when the capability state indicates an executive state, it is arranged to operate in a manner less constrained than when in the default state, so as to allow modification of the capability domain. The capabilities may comprise bounded pointers.
