Title: Intuitive editing of three-dimensional models
Inventor: Siddhartha Chaudhuri
IPC: G06T19/20
Filed: 2019-08-12
Abstract: Editing 3D models, comprising: identifying salient geometric features of a 3D model and determining attributes associated therewith; using the attributes to generate a feature set including multiple related geometric features; displaying an editing handle for the feature set, in association with one of the features, that enables each of the features within the feature set to be edited by manipulating the handle. Also disclosed is propagating rotation, translation, or scaling edits to a second feature set within a region of influence and updating the model. Salient features may be prominent or noticeable and include curves, wires, or line segments. Attributes may include properties such as linearity or circularity, or relationships such as co-planarity, parallelism, symmetry, concentricity, spatial distance, angle, proximity. Features may be clustered or grouped into sets or related in a hierarchical structure comprising parent and child nodes. Attributes may be weighted to determine relationships between features. Editing handles may be tools provided for selection and movement via a graphical user interface and visual emphasis (eg. colour, line width) may show their relationship to a feature set. Region of influence may be determined via machine learning or heuristically and a slider may increase or decrease its size.

IPC: F24H4/04
Filed: 2021-07-02
Abstract: A hot water supply for a building is heated by an instantaneous (tankless) water heater. The heater comprises a heat pump 120 to heat water via a heat exchanger disposed in a thermal store 140 containing an energy storage material. A processor 150 controls the heat pump based upon measurements from one or more flow sensors 170 that detect opening of an outlet 130 of the hot water supply. A sufficient mass of material is provided in the thermal store to heat water to a predetermined temperature using thermal energy of the material whilst the heat pump initialises/activates and gets up to a useful operating temperature that can heat the water. An electric heater 220 controlled by the processor based on readings from temperature sensors 210 can be used to accommodate shortfalls in heating by the material and/or heat pump. The processor may not start the heat pump at all if the flow sensors indicate a small water draw from the outlet that can be heated entirely by the material.
Patent GB-2611205-A (GB)
Title: Selective capture of target DNA sequences
Inventor: JOHN F THOMPSON
IPC: C12Q1/68
Filed: 2021-05-10
Abstract: Many regions of genomic DNA are highly similar to other regions of the genome and thus are very difficult to capture without also capturing the similar, undesired regions. This leads to over-sequencing of regions for which there is no interest and lowers coverage of the desired regions. To minimize the capture of non-desired regions, blocking baits have been designed to prevent similar but non-desired fragments from being captured. This allows more directed sequencing of the regions of interest. Blocking baits differ from capture baits in that they have modestly different sequence that preferentially bind the non-desired DNA and do not contain a biotin or other modification so remain behind when the capture baits are selected.
