Title: Halftoning method
Inventor: KLAUS JULIUS DAHLSETH
IPC: H04N1/409
Filed: 2018-08-08
Abstract: A method for compensating for dot gain in a single channel image comprises: receiving a source grey tone image, each pixel having a binary value that corresponds to a grey level; generating a dithered (FM) image (Figure 10B), e.g. comprising error diffusion, from the grey tone image, the dithered image comprising an array of same size and shape as the source image, each pixel having a single bit binary value that corresponds to a dithered grey level; forming an output image the same size and shape as the source image by applying the dithered image as a mask to the source image; and if a pixel value in the dithered image is 0, the grey level in the source image pixel is copied to a corresponding output image pixel; and if a pixel value in the dithered image is 1 (one), a maximum value corresponding to maximum white is copied to a corresponding output image pixel; and a halftone (AM) raster (Figure 10E-G) is applied to the output image, which is used to make a printing plate. Alternatively, the method is applied to multi-channel colour images, processing pixel brightness levels; the dithered image may represent weighted brightness.

Title: Priority mechanism for short feedback procedures in wireless networks
Inventor: PATRICE NEZOU
IPC: H04W74/08
Filed: 2019-07-04
Abstract: An access point transmits a null data packet (NDP) feedback report poll (NFRP) trigger frame. A station selects one of the resource units (tones) defined by this trigger frame, performs carrier sensing over a defined period, then transmits a NDP feedback poll response if the resource is idle. This sensing may be performed only by lower-priority stations, with higher-priority stations transmitting from the start of the period. The priority level of a station may be determined by the access category of the data it has to send, or by its association identifier (AID). The NFRP trigger frame may include a flag indicating whether this prioritisation mechanism is in use. The sensing period may include a preamble period and a subsequent energy-sensing period: if the lower-priority station detects a PHY preamble it then performs energy sensing, and if the resource remains idle, its NDP response comprises only a transmission of energy (without a preamble). This short feedback procedure may be used in an 802.11ax WLAN.
