Title: Determining available dynamic turing radius
Inventor: DEXIN WANG
IPC: B62D15/02
Filed: 2017-08-18
Abstract: A system, which includes a programmed computing device, is provided that determines a transition in performance of a steering system actuator (20, Figure 3) of a vehicle to a diminished operating mode and determines a manoeuvrable envelope of vehicle velocity and path curvature adapted to the diminished operating mode (steps 79, 80). A vehicle velocity is then selected within the envelope for a path curvature (step 81). Typically two redundant windings may be provided on a power steering motor and only one winding may be available in the diminished steering mode. The envelope may be determined based on a functional relationship between lateral acceleration and rack force. The system is particularly suitable for use with an autonomous vehicle and may allow dynamic adaptation of the turning radius to available steering performance.

Title: Portable vacuum window cleaning device
Inventor: ALLAN JOHN BROWN
IPC: A47L1/08
Filed: 2017-09-03
Abstract: A handheld vacuum-powered cleaner for cleaning flat surfaces such as windows or glass comprises a cleaning fluid reservoir 6, 9, a squeegee 2, a cleaning fluid applicator 1, a pressurised pumping system 4, a spraying mechanism 17 and a vacuum suction mechanism 3. The applicator is arranged parallel to the squeegee blade, and is shorter than the blade. The pressurised pumping system transports cleaning fluid from the reservoir and, in response to user input 11, sprays the cleaning fluid onto the applicator. The vacuum suction mechanism collects used cleaning fluid left behind by the applicator. Used cleaning fluid may be funnelled from the vacuum suction mechanism into a second reservoir, and the two reservoirs may be connected by a gravity fed, filtered one-way valve. The filter may be removable. The squeegee may be hinged 5 and may raise and lower in response to user input 8. The applicator may comprise a scouring pad. Any of the reservoirs may be transparent. The squeegee blade ends may be turned towards the applicator, and may have scrim or microfiber pads behind them. Used cleaning fluid may be recycled by exhausting used fluid back to the applicator for reuse.

Title: A method of displaying a hologram on a display device comprising pixels
Inventor: JAMIESON CHRISTMAS
IPC: H04N9/31
Filed: 2018-05-25
Abstract: A holographic projector comprises a hologram engine and a controller. The hologram engine is arranged to provide a hologram comprising a plurality of hologram pixels, each hologram pixel having a respective hologram pixel value. The controller is arranged to selectively-drive a plurality of light-modulating pixels on a spatial light modulator (SLM) so as to display the hologram. Displaying the hologram comprises displaying each hologram pixel value on a contiguous group of SLM light-modulating pixels such that there is a one-to-many correlation/mapping between hologram pixels and the SLM pixels. The displayed hologram undergoes an inverse Fourier transform to form a holographic reconstruction image at a replay field (e.g. screen 125, figure 1). Figure 5 illustrates how each hologram pixel value (e.g. 11,12,13 etc) may be represented by 16 SLM pixels. The pixel mapping is software-controllable such that a different number of SLM pixels may be used to represent each hologram pixel (see e.g. figures 6,7). By altering the hologram-to-SLM pixel mapping relationship, the size of the projected image in the replay field may be controlled. Accordingly, the pixel mapping control may be used to control the relative size of component R,G,B holographic reconstruction images at the replay field in order to form a composite colour replay field with colour component images of substantially the same size.
