Title: Scalable parallel tessellation
Inventor: JOHN HOWSON
IPC: G06T17/20
Filed: 2018-07-13
Abstract: Tessellating a patch to generate tessellated geometry data representing the tessellated patch comprises processing received geometry data (300) representing the patch to identify patch tessellation factors (510). Tessellation instances are determined (520) based on the identified factors. The instances are allocated (e.g. by a distributor (523)) amongst a plurality of tessellation pipelines operating in parallel (530), wherein a respective set of one or more of the instances is allocated to each pipeline, and wherein each pipeline generates tessellated geometry data associated with the respective allocated set, e.g. then stored in memory (540). Tessellation factors are values that define the level of granularity to which the patch is to be tessellated – the factors therefore define the amount of tessellation to be performed on the patch, and the number of primitives to be generated. Tessellation instances identify an amount of work required to be performed to tessellate the whole or a portion of the patch. Also claimed is a multi-core arrangement (see figs. 9&10) with each core performing the above method separately.

IPC: H02S30/00
Filed: 2018-08-16
Abstract: A sustainable building design to reduce global emissions which can be applied to new buildings or retrofitted to existing buildings. The building provides a high surface area to maximize solar absorption for electricity generation. This can be achieved using a solar ledge which comprises photovoltaic (PV) panels around the circumference or perimeter of the building (figures 1-3). Alternatively solar tubes may be used, each tube having PV cells provided on an inner surface, and a refracting dome at the top of the tube and convex mirror at the base (figures 4-7). A heat sponge or thermal capacitor absorbs light to increase air or building temperature which is utilized in a heat exchanger and heat pump (figure 8). Heat is also recovered from waste water (figure 11) and/or mains water. Solar gain can be increased by the transparency of the building or by using dark cladding material or dark paint. Air insulation is provided by increasing the thermal barrier of still air around the building. The building reduces sheer forces from wind (figure 15) and uses a cellular design of the structure (figure 16).

Title: Property categorisation tool
Inventor: SALLY AMELIA HOLDWAY
IPC: G06Q50/18
Filed: 2018-11-18
Abstract: A property conveyancing app that assess known property data to inform home movers and other players in the property market of conveyancing issues surrounding a property. Parties can be informed i) how long conveyancing may take; ii) how complex the transaction may be; and iii) of conveyancing issues; that affect the property from the outset of or before marketing a property. This may allow a seller to answer questions early to seed up the transaction process, allowing for a faster ‘potential move date’ to be presented to home movers. The app uses Land Registry data and interrogates the title deed entries e.g. class of title, property ownership, length of ownership, notice, restrictions, bankruptcy, leases, cautions, home rights, rent charges, right to buy or death of proprietor, by applying industry accepted due diligence questions to the entries. Each conveyancing issue is given a complexity rating percentage, and timescale referenced to industry standards of how long each issue will take to resolve. The complexity rating percentages and time adjustments for each issue are used to adjust a base (pre-adjusted) timescale and complexity rating. The complexity rating may aid purchasers in buying decisions and may be used by lenders regarding mortgage offers.

Title: Transaction verification of distributed ledgers
Inventor: EVANDRO PIOLIMORO
IPC: H04L29/08
Filed: 2019-03-06
Abstract: A distributed ledger process, such as a blockchain system, posts transactions between nodes in a network. Transaction data generated in respect of a data node, such as an Internet of Things (IoT) sensor, are validated by comparison with a data source of permitted transaction data types to be generated in respect of the data node, and transaction is posted to the distributed ledger 240 only if it is identified as permitted. Transaction verification data checks embodied include access permissions, including verifying the role of the node 214, expected periodicity of measurement 220 (to avoid flooding/clogging), whether a measure is within an expected range 222, and a packet size check 224. The check can identify invalid transactions such as anomalous readings or nodes that are not conforming or consistent with an expected pattern of reporting of sensor values. The transactions are performed as blockchain transaction or using a Directed Acyclic Graph (DAG) structure. The checking may be performed by a smart contract or by a transaction explorer interface. The validation of transactions may be performed by determining a compound score 213 from multiple checks and comparison to a threshold.

Title: Predicting downhole fluid mixing and channeling in wellbores
Inventor: VITOR LOPES PEREIRA
IPC: E21B41/00
Filed: 2018-12-31
Abstract: Effective prediction of downhole mixing and channeling at an interface between two or more wellbore fluids may prevent the unnecessary consumption of resources at a well site and enhance the performance of wellbore operations, including drilling operations, completion operations, and reservoir management. A model for a length and a volume of the interface between two wellbore fluids may be used to characterize the amount of mixing and channeling. The model may use known properties of the wellbore fluids before mixing and channeling occurs. The model may account for eccentricity in an annulus of the wellbore by partitioning a three dimensional flow profile in the wellbore into a plurality of segments for separate analysis. Outputs from the model may be used to determine one or more locations of the interface at one or more intervals of time as the wellbore fluids circulate through the wellbore. One or more compositions may be determined and recorded for one or more wellbore fluids at one or more depths of the wellbore during one or more intervals of time. To improve operational decision making at a well site, operators or automated processes may modify a wellbore operation based, at least in part, on the one or more compositions and the one dimensional model for mixing and channeling.
