Title: Method for processing frames of an input video image
Inventor: Michael adam
IPC: H04N5/21
Filed: 2017-07-07
Abstract: A method for processing frames of an input video 1 by means of at least one reference image and for generating an output video 2 from the processed frames, is characterized by the steps of: ongoing updating S1 of the reference image using the frame currently to be processed; calculating S2 an optical flow between the frame to be processed and the reference image; and processing S3 the frame by distorting the frame by means of the calculated optical flow. The reference image may be updated by an average-value image calculated pixel-by-pixel, using an average value formed from a number of n previously processed frames and the frame currently to be processed, or a moving, in particular, weighted, average. Alternatively, the reference image may be similarly updated but by a median image calculated pixel-by-pixel or using a moving median. Output image 2 may be formed by pixel-by-pixel updating of a second average-value with the currently processed frame, the second average-value image formed from a number m of previously processed frames or moving (particularly weighted) average. A sharpness filter may be applied to the second average-value image.

Title: Creep assist for steering management
Inventor: John p joyce
IPC: B62D15/02
Filed: 2017-08-22
Abstract: A method of controlling a vehicle steering system includes determining the necessary rack force needed to displace a steering rack 24 and the force available from an actuator 26. If the rack force available is less than that needed, vehicle movement is initiated and actuator 26 is activated when the vehicle is in motion. A relationship between vehicle velocity and necessary rack force may be determined, which may be a band depending on the road surface or other environmental factors. Typically, a target vehicle speed may be determined and the vehicle speed increased to this target speed before the actuator is activated; optionally, the vehicle speed can be increased if no displacement of the steering rack is detected. Uneven drive or brake force may be applied to wheels 14 to develop a torque vector.

Title: Using eddy currents of exhaled breath for authentication
Inventor: ROD D WALTERMANN
IPC: G06T7/00
Filed: 2017-08-28
Abstract: A device comprises a camera able to acquire images of a persons breath. The images may be infrared (IR) images. An initial imaging step 302 establishes a template/reference image which is characteristic of that person. At a later stage, subsequent images may be captured 304 and compared 306 to the template. If a match is determined authentication is successful 310, enabling the user to use the computer/device. If a match is unsuccessful 312 the authentication fails and computer/device operation is limited. Upon authentication failure, the user may be prompted to enter a secret pass code to unlock the template generation step 300. The images may include images of eddy currents in the users exhaled breath. The analysis may investigate breath peridocity/interval to determine authentication. The images may comprise oral breath images or nasal breath images. The device includes a processor with storage accessible thereto on which instructions are stored to undertake the aforementioned authentication process.

Title: Packing element back-up system incorporating iris mechanism
Inventor: LORN SCOTT MACDONALD
IPC: E21B33/12
Filed: 2015-05-29
Abstract: An annular sealing assembly and method are disclosed. The assembly includes a mandrel and an expandable element disposed around the mandrel which expands to seal against the inner diameter of a tubing or casing string. The expandable element seals the mandrel from the annulus between the mandrel and the tubing string. The assembly includes at least one back¬ up element having a plurality of pivoting blades circumferentially secured in a ring around the mandrel. The back-up element is capable of radially expanding and contracting upon longitudinal movement along, and engagement with, a generally ring-shaped ramp. A guide ring guides the back-up element along the guide ramp. The method is directed to expanding the expandable element to seal the annulus and the back-up element so the blades come in contact with the inner diameter of the tubing string preventing the expandable element from extruding outward into the annulus beyond the back-up element.

Title: Processing packets in a computer system
Inventor: ANTTI-PEKKA LIEDES
IPC: H04L29/06
Filed: 2018-03-02
Abstract: Methods for the transmission and reception of packets between apparatus that utilise a packet sequence number and a flow identifier in each packet. The flow identifier identifies a security association for the packet flow and is determined in dependence on the sequence number, such as from a quantity of the least or most significant bits of the sequence number. The invention may be utilised where anti-replay protection is required for packet flows, such as those using the IPSec protocol. A bit pattern from the flow identifier may be utilised to split the received packets between various separate packet processing entities. Each processing entity then examines a specific quantity of the least significant bits of the sequence number to determine whether a packet has arrived out of sequence. The flow identifier may be derived as a function of the Security Parameters Index (SPI) of an Encapsulating Security Payload (ESP) header and the relevant sequence number within that header. The flow identifier may then act as an effective SPI and may occupy the field normally reserved for the SPI.

Abstract: Apparatus for removing powder from a powder-based additively manufactured part, comprises a chamber 106 to contain a fluid, a device to induce flow in the fluid to agitate and remove powder from a part within the chamber. An ultrasound transducer 121 produces waves in the or a further fluid to agitate and remove powder. A chamber (134 Figure 1B) has a mesh for supporting a powder cake having an additively formed part within, and an inlet for gas to flow through the cake to fluidise powder and disengage the part. Gas and loose powder can exit through outlet (137). Air and liquid carbon dioxide are mixed to form crystals of carbon dioxide which are sprayed onto a powder-based additively manufactured part and then rapidly expanded to disengage un-sintered powder. Un-sintered powder of an additively manufactured part within a chamber may comprise fluid (such as water) which, by applying negative pressure to the chamber, may be induced to boil and expand to disengage the un-sintered powder. An elongate member, which may be formed by additive manufacturing, within a powder cake is removed to define a channel in the cake through which cooling fluid may flow to transfer heat from the cake.
