Title: Dual SCR system control method
Inventor: MICHAEL PARMENTIER
IPC: F01N9/00
Filed: 2019-11-25
Abstract: A vehicle exhaust system comprises a first SCR catalytic unit 1 and a second SCR catalytic unit 2 located downstream of the first unit. A first urea doser 3 injects reductant upstream of said first unit, and a second urea doser 4 injects urea upstream of the second catalytic unit. A method of controlling the second doser comprises determining a desired NH3 slip fraction through the first SCR unit based on operating conditions of the first SCR unit, and controlling the operation of the second doser based on the desired NH3 slip fraction. The desired NH3 slip fraction may be determined from the temperature of the first SCR unit or, where the first SCR unit has DPF functionality, the soot loading of the first SCR unit. The slip fraction may be defined as a/(a+b) where a is the desired NH3 slip and b is the NH3 flow provided by the second doser.

Title: Hardware implementation of a neural network
Inventor: Xiran Huang
IPC: G06N3/063
Filed: 2019-11-29
Abstract: A neural network, e.g. convolutional-neural-network (CNN), has first layer 502-1 receiving input data 504 and end layer 502-2 generating output data 508. Off-chip SDRAM DDR memory 312 stores input data, weights, and output data. Generated output data comprises p data-set planes 508 dependent on weights, each plane comprising n>2 output data elements. Processing of inputs proceeds depth‑wise through each layer by reading a first block of input data and weights, then evaluating each layer to calculate a first block of output data and writing it to memory 312. The first output block has multiple data elements m, with m>1, m<n. The CNN also uses on-chip memory 314 for intermediate data, which is smaller but quicker than memory 312. Memory 314 stores non-disposable output of a layer retained in double-buffered section and disposable output of the layer which can be overwritten or deleted. Depth-first processing of subsets of input data reduces memory access overheads making it practical using ON-chip memory for intermediate data compared to evaluating each layer in its entirety. Multiple output data elements in one pass exploit overlapping data dependencies to reduce memory bandwidth in parallel implementations.

Title: Adaptive virtual objects in augmented reality
Inventor: PEDRO FEDERICO QUIJADA LEYTON
IPC: G06T19/00
Filed: 2022-07-25
Abstract: A computer-implemented method comprises selecting a virtual object to be positioned in a mixed-reality environment, the virtual object having one or more conditions relating to the positioning of the virtual object and then scanning a real-world part of the mixed-reality environment. The method further comprises determining a location to position the virtual object based on the scan, the location satisfying the positioning conditions. After determining a location, the method comprises scaling the virtual object to fit the location and finally, positioning the virtual object in the mixed-reality environment at the determined location. Determining the location may comprise comparing the real-world environment with the conditions relating to positioning of the virtual object. The comparison may be performed continuously or at intervals, for example during or after the scanning process. The positioning conditions may relate to a bounding box (3D mesh) of the virtual object, locating the virtual object on a certain type of plane (wall, tabletop, chair), a proximity to another object, lighting conditions or a distance from the user. Scaling the virtual object provides additional flexibility to adapt the virtual object to the local real-world environment and so enhance the overall mixed reality experience of the user.
