Title: Process and catalyst
Inventor: ANDREW GEORGE HILES
IPC: C07C17/25
Filed: 2016-05-26
Abstract: A process for the production of vinyl chloride comprises the step of passing a feed stream comprising ethylene dichloride (EDC) over a catalyst system comprising a dehydrochlorination catalyst and a hydrochlorination catalyst at a temperature, which may be in the range 150 — 350 °C, sufficient to effect dehydrochlorination of the ethylene dichloride to produce vinyl chloride. The process avoids or reduces the requirement to recycle a product stream comprising acetylene or ethylene.

Title: Lane boundary detection data generation in virtual environment
Inventor: Ashley Elizabeth Micks
IPC: G06N99/00
Filed: 2016-10-11
Abstract: A method and an apparatus pertaining to generating training data. The method may include executing a simulation process. The simulation process may include traversing one or more virtual sensors (191 193) over a virtual driving environment defining a plurality of lane markings (such as 110, 150, 120, 130, 150) or virtual objects (such as 160, 181, 183) that can be sensed by the one or more virtual sensors. During the traversing, each of the one or more virtual sensors may be moved with respect to the virtual driving environment as dictated by a vehicle-dynamic model modeling motion of a vehicle driving on a virtual road surface of the virtual driving environment while carrying the one or more virtual sensors. Virtual sensor data characterizing the virtual driving environment may be recorded. The virtual sensor data may correspond to what an actual sensor would produce in a real-world environment that is similar or substantially matching the virtual driving environment. The advantage of this is that the cost and time required to gather such data from real sensors during actual driving is avoided.

Title: System for monitoring linearity of down-hole pumping systems during deployment and related methods
Inventor: ROBERT M HARMAN
IPC: E21B47/02
Filed: 2011-09-21
Abstract: A method for monitoring linearity of a down-hole pumping system assembly 31 during deployment within a bore 29 of a casing 23 of a well 20 positioned to extract hydrocarbons from a subterranean reservoir 21 comprises selecting an optimal operational position for the down-hole pumping system assembly 31 within the bore. The method includes the step of detecting linearity of the assembly during deployment to a position below and adjacent to an initial target operational position for the assembly. The target position is then adjusted in response to linearity determinations above and below the initial target position when the linearity detected at the initial target position is less than the linearity at either position directly above or directly below the initial target position. A system for monitoring linearity includes the use of optical fibre to measure axial strain in the outer casing of a pump assembly.

Title: Installing application program code on a vehicle control system
Inventor: Simon William Packwood
IPC: G06F8/60
Filed: 2018-08-29
Abstract: A method and control system for avoiding bricking on a vehicle wherein application program code is downloaded via an interface S501, installed S502, and it is determined whether the control system can still communicate whether an external device S503 and the installed program is subsequently loaded on start-up based on whether the system could communicate with the external device S508. The system may be configured to load the application on each start-up of the control system, this may be accomplished by setting a flag in memory on determination that the external device was contacted S504 and checking this flag on each start-up S507. If the external device was not contacted, the system may be restarted without launching the installed program S509 and replacement program code may be obtained and installed S510-S511. The replacement program may be a backup of the previous application code that was replaced by the update. Determination of communication with the external device may be accomplished by launching the installed program, receiving data from the external device and saving it to memory and then comparing the received data with a pre-stored copy of the data.

Title: Detecting objects using a weakly supervised model
Inventor: Delun Du
IPC: G06N3/02
Filed: 2018-10-29
Abstract: The invention provides systems and methods for detecting an object in an input image based on a target object keyword (e.g. people). A heat map 310a of the input image 306 is generated based on the target object keyword. Various bounding boxes 314a, based on a pixel analysis of the heat map, are then derived. One or more centre boxes 316a are then generated from the bounding boxes using local thresholds. Object location proposals 318a,b,c are also determined based on the keyword. The bounding boxes are then used to determine scores for the object location proposals and the box 318c for the highest scoring object location proposal is overlaid on the input image. The object location proposals could be derived using a YOLO algorithm. The heat map could be generated using a fully-convolutional dense tagging network. The method could also employ a weakly supervised model which avoids some of the costs of a learning process.
