Title: Apparatus for adjusting a tension mat
Inventor: DAVID WITHEY
IPC: B60N2/72
Filed: 2018-12-07
Abstract: Adjusting a tension mat 7 attached to a vehicle seat frame 4, 5, 6. A member 12 (e.g. a two part sleeve located around the base cross tube 6, see figure 6) rotates about an axis 13, causing a first end 71 of the tension mat 7 attached to the sleeve to move in an arc, for example from lowered (figure 3) through intermediate (figure 4) to raised (figure 5) positions. The other end 72 of the mat may be anchored to the frame, meaning sleeve rotation alters the mat tension, allowing compliance/ firmness adjustment for greater comfort and easier entry to or egress from the vehicle. The mat may include a wire frame, e.g. of spring steel, with hooks 18 to engage eyelets 11, (17; fig. 60) on the sleeve. There may be an electric motor (24; fig. 6) which powers a worm gear meshing with a pinion gear (22; fig. 6) which directly drives the rotation of the sleeve via a toothed segment (21; fig. 6). The rotation may be limited to prevent the mat wrapping around the sleeve, e.g. allowing up to a 90 degree angle from intermediate to respective raised and lowered positions.

Title: Holographic projector
Inventor: MICHAL WENGIEROW
IPC: G03H1/26
Filed: 2019-08-23
Abstract: A holographic projector comprises an image processing engine, a hologram engine, a display engine and a light source. The image processing engine receives a source image for projection and generates a plurality of secondary images from the source image. The source image comprises pixels. Each secondary image comprises fewer pixels than the source image. The hologram engine determines a hologram corresponding to each secondary image to form a plurality of holograms. The display engine displays each hologram in turn on the display device, such that the rapid temporal sequencing of sub-holograms is perceived as a single image. Preferably, the secondary images are sampled from the primary image in complementary checkerboard patterns. There may be more than two secondary images. The secondary images may alternatively be sampled by applying a filter, e.g. a Gaussian filter, to respective blocks of pixels. A second secondary image may be derived by diagonally offsetting the block boundaries before filtering.
