Title: Method and apparatus for image frame identification
Inventor: ARTO VUORI
IPC: H04N21/84
Filed: 2013-10-03
Abstract: A method and apparatus 300 are provided for identifying image frames 10 in a video stream, by extracting noise features to provide digest values 310. According to the invention, a digest producing unit 300 receives a video stream and applies noise filtering 901 to each original image frame of the video stream, to produce a respective noise filtered image frame. An image frame subtraction unit 902 subtracts the original image frame from the noise filtered image frame to produce a noise residual image frame. A dimension reduction unit 903 then provides a digest value for each original frame, the digest value being derived from the respective noise residual image frame. The digest values may be recorded in a digest record (410, fig.3), for several video streams. Digest values from a candidate video stream may then be compared against the recorded digest values. A match of digest values indicates matching images. In embodiments, a nearest neighbour ratio (NNR) may be used as a threshold in matching. The use of an LSB histogram is also disclosed.

Abstract: A method of detecting that a particulate filter 280 of an internal combustion engine 100 is clean from soot, comprising: determining a value of a fuel quantity supplied into the internal combustion engine 110; determining a value of a tem­perature of the particulate filter 280; determining a value of an oxygen content in an ex­haust gas discharged from the particulate filter 280; identifying that the particulate filter 280 is clean from soot, if the following concurrent conditions are met: the fuel quantity value is zero, the temperature value is equal to or larger than a predetermined threshold value thereof, and the oxygen content value is equal to a reference value of the oxygen content in an intake air. This method provides an alternative method of monitoring the level of particulate build-up in a particulate filter that may be performed when the engine is in a deceleration fuel cut-off condition, or over-run condition.

Title: Multi-Z polylines intersection points editing
Inventor: NAM XUAN NGUYEN
IPC: G06T17/05
Filed: 2014-04-01
Abstract: Method and system for 3-D imaging of subterranean geologic structures based on seismic data interpretations involves correcting mis-ties that arise as a result of orthogonal polylines failing to intersect due to inconsistencies in seismic interpretations. In some embodiments, the mis-ties may be corrected by adding a data point from one polyline at or near the mis-tie to the other polyline, and vice versa for the other polyline. The two data points are then adjusted so they coincide or merge. The merged data point is then used as intersection points for the polylines and associated with one another such that a change made to one intersection point is automatically made to the other intersection point. In some embodiments, one or more neighboring data points on each polyline are adjusted to smooth out the polyline at the point of the corrected mis-tie.

Title: Vehicle winch control system and method of controlling a winch
Inventor: JEREMY GREENWOOD
IPC: B66D3/00
Filed: 2013-03-26
Abstract: A control system 110C to control winding speed of a winch 110 on a vehicle 100, the winch 110 having electric motor 116, winding speed being dependent on a speed of rotation of the vehicle powertrain, for instance wheel 102, 104 speed, and so as to limit to a substantially constant prescribed winch cable 114 line tension. Winding speed may be proportional to powertrain speed. The speed at which the vehicle 100 is pulled over-ground may be equal to a speed at which the vehicle would be driven over ground if there were no significant wheel slip. The prescribed value of winch cable 114 line tension may be selected through a user input device (figure 3). The system may limit to a substantially constant prescribed value of torque applied to the drum 112, may apply a brake torque to the winch drum 112, which may effect regenerative braking, and may limit the rate of increase of torque applied to the drum 112 to the prescribed value. Power supply potential may be between 110V and 5kV. The vehicle may be electric or hybrid.

Title: Method for fine timing synchronisation
Inventor: Kasper Ornstein Mecklenburg
IPC: H04W56/00
Filed: 2018-02-21
Abstract: There is described a method of determining the base station timing offset of a received NB-IoT (Narrowband Internet of Things) signal comprising a Narrowband Primary Synchronisation Signal (NPSS), the NPSS having a known, predetermined sequence of symbols. The method includes storing a set of accumulation values S4, the accumulation values in the set comprise terms derived from samples taken from the signal at timings corresponding to the predetermined sequence of symbols. The method further includes determining a cross-correlation between the set of accumulation values and a portion of the predetermined sequence of symbols S5; and determining, from the cross-correlation, which of a set of candidate timing offsets corresponds to the timing offset of the received signal S6. The method may determine the fine timing once the UE has determined the course timing estimation to a precision of at least plus or minus half a symbol in devices which may be low-cost or lower power NB-IoT devices with limited computational resources. Determining accumulation values in hardware circuitry may allow the central processing unit of the device to be used for other purposes while the accumulation values are being determined.
