Title: Holographic image display apparatus
Inventor: FAN YANG
IPC: G03H1/26
Filed: 2017-06-28
Abstract: An apparatus for projecting a three-dimensional holographic image includes a coherent light source 6 and beam expander optics 8 which transmit light onto spatial light modulator (SLM) 4. Under control from processor 5, SLM 4 performs amplitude modulation to impart an amplitude pattern representative of a 2D slice of the desired 3D image projection onto the light beam. The amplitude-patterned light is subject to a Fourier transform by a lens arrangement (e.g. lens 3). The Fourier transform of the amplitude-patterned light is brought to focus upon a further, phase-modulating, SLM 2 which performs a Fresnel transform upon the light incident upon it. SLM 2 is also subject to control from processor 5. The Fresnel transform provides a lensing effect, thus different phase-modulating patterns enable associated 2D holographic image slices to be focused in adjacent image planes. Rapid sequential display of different 2D image slices is used to generate the perception of a 3D projected holographic image in the image space. Embodiments include alternative lens arrangements including a phase mask (31, figure 2) to impart a pseudo-random phase pattern on the beam to reduce noise in the projected image. An associated method of generating a holographic image is also disclosed. The disclosed apparatus and method are intended to enable rapid generation of a holographic projection without requiring processor-intensive computation of Fourier transforms of the image slices.

Title: Detection of lane-splitting motorcycles
Inventor: Shant Tokatyan
IPC: G08G1/16
Filed: 2017-11-16
Abstract: A controller 102 receives images from a rearward-facing camera 104 having an inter-lane region in the field of view. A region of interest of the images is identified corresponding to the inter-lane region, the images are converted to grayscale images having a drastically reduced number of intensity levels. A difference image is determined between the grayscale image for each image relative to the grayscale image of a preceding image. If the non-zero pixels in the difference image exceed a threshold and the area of non-zero pixels in the difference images for the input images are increasing with time, a lane-splitting vehicle 304 will be determined to be present and an alert may be generated and/or autonomous lane changes may be suppressed. A third image may be converted to a grayscale image and used to produce a second comparison image with either the first of second images, this second comparison image may also then be compared to a threshold for non-zero pixels to determine motion of objects.

Title: Glow ignition detection in an internal combustion engine
Inventor: STEPHANE RANDAZZO
IPC: G01M15/11
Filed: 2018-10-19
Abstract: Disclosed is a method for monitoring glow ignition in a spark-ignition internal combustion engine. The method comprises: monitoring a crankshaft speed of the engine over a detection window corresponding to a crankshaft deceleration phase during a compression stroke in a given engine cylinder; determining a glow indicator based on a crankshaft speed deceleration gradient between two points defined by their respective crankshaft speed and crank angle, wherein the first point (Pinit) is defined by a predetermined crankshaft angle and corresponding speed during said deceleration, and the second point (Pmin) is a point of lowest speed reached during said deceleration. The method then compares the glow indicator to a predetermined threshold in order to detect the presence or absence of glow ignition. The method uses the fact that early ignition causes the crankshaft to slow before the point at which spark-ignition should occur. The first point, which is defined by a predetermined crankshaft angle and a corresponding speed, may be selected so that it is a stable fixed point. The second point will vary noticeably between normal ignition and early ignition, since the lowest speed will be reached earlier when there is glow ignition than is the case with normal ignition, and this will noticeably change the gradient between the two points allowing detection of glow ignition. Glow ignition may be caused by hot spots in the cylinder or incandescent particles in the air-fuel mix in the cylinder.
