Title: OFDM channel estimate interpolator which calculates virtual replacement pilot at discontinuities in scattered pilot pattern
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: H04L25/02
Filed: 2011-03-17
Abstract: Orthogonal frequency division multiplex (OFDM) systems typically use scattered pilot training symbols for channel response estimation, from which channel responses of data sub-carriers are interpolated. These are typically arranged in regular repeating patterns, however there can be discontinuities in these patterns (eg. at a frame boundary, see Figs. 3,5). The interpolator comprises an FIR filter 214.1 which operates on the expected 212 and received 208 received symbols. The filter requires the regular repeating pattern for correct operation. Where a break in the pattern causes an irregularity the controller 320.1 causes the re-sample generator 324.1 to create virtual pilots to maintain the pattern. The new pilot sample location 466 is kept and the older samples 464 are discarded and replaced with calculated pilot samples 470 in the correct pattern position (see Fig. 10d). The invention may be applied in DVB-T2 systems.

Title: Auto-focus image system
Inventor: TAY HIOK-NAM
IPC: G02B7/36
Filed: 2010-12-07
Abstract: An auto focus image system that includes a pixel array coupled to a focus signal generator. The pixel array captures an image that has at least one edge with a width. The focus signal generator may generate a focus signal that is a function of the edge width and/or statistics of edge widths. A processor receives the focus signal and/or the statistics of edge widths and adjusts a focus position of a focus lens. The edge width can be determined by various techniques including the use of gradients. A histogram of edge widths may be used to determine whether a particular image is focused or unfocused. A histogram with a large population of thin edge widths is indicative of a focused image. The generator may eliminate an edge having an asymmetry of a gradient profile of an image signal. The generator may also eliminate an edge that fails a template for an associated peaking of the gradient.

Title: Hybrid vehicle and boost control for gradients
Inventor: DEXTREIT CLEMENT
IPC: B60W20/00
Filed: 2012-12-10
Abstract: A hybrid electric vehicle 100 comprises control means and a powertrain comprising an electric propulsion motor (123 see fig 1) and an engine (121 see fig 1), the powertrain being operable by the control means in an electric vehicle (EV) mode with the engine (121) remaining switched off and in a boost mode in which the engine (121) provides additional power to drive the vehicle 100. The control means allow a driver to set a target vehicle speed and the control means controls the powertrain to maintain the target vehicle speed. In the EV mode the control means is further operable to determine whether a boost location exists ahead of the vehicle 100 at which a gradient of a driving surface is sufficiently high to require assumption of the boost mode in order to maintain the target vehicle speed. The control means commands starting of the engine (121) before the boost location is reached. The invention seeks to avoid excessive noise, vibration and harshness which can be associated with a transition of a powertrain from EV mode to parallel mode when driver demand is high.
