摘要： An ignition chamber (5, 51, 52, 53, 54) for indirect ignition in a gas spark-ignition internal combustion piston engine projecting at least with its face into a main combustion space (3), in which a spark gap (10) of a spark plug (9) is arranged, whereby gaseous fuel supply duct (8, 81, 82) opens into an ignition chamber (5, 51, 52, 53, 54) in the vicinity of its face opposite the face which projects into the main combustion space (3) and the inner space (7) of the ignition chamber (5, 51, 52, 53, 54) and the main combustion space (3) of the engine cylinder are interconnected by at least two communicating orifices (11, 111, 12, 121, 122). The axis (X 2 ) of one part of the communicating orifices (11, 111) forms an angle (β 2 ) with the longitudinal axis (6) of the ignition chamber (5, 51, 52, 53, 54), the angle (β 2 ) being at least by 3° greater than the angle (β 1 ), which the axis (X 1 ) of the second part of the communicating orifices (12, 121, 122) forms with the longitudinal axis (6) of the ignition chamber (5, 51, 52, 53, 54), whereby the gaseous supply duct /8, 81, 82) opens into the inner space (7) of the ignition chamber (5, 51, 52, 53, 54).

摘要： We propose a stroke, i.e. a general curvilinear structure, detector based on pixel intensity comparisons in a local neighborhood. When applied to text detection, stroke-specific keypoints are detected. Text fragments are subsequently extracted possibly by local thresholding or a segmentation procedure guided by keypoint properties. Classification based on "strokeness" feature eliminates non-text segmentations. The proposed stroke-specific keypoints detector is scale- and rotation invariant. When applied to text detection, it is significantly faster and produces significantly less false detections than the detectors commonly used in scene text localization. The proposed stroke-specific keypoints detector produces 2 times less segmentations and detects 25% more characters than the commonly exploited MSER detector and the process is 4 times faster. After an efficient classification step, the number of segmentations is reduced to 7 times less than the standard method and is still almost 3 times faster. The proposed stroke-specific detector detects a wide variety of scripts (Latin, Hebrew, Chinese, etc.) and fonts. The detector is applicable to the problems where linear structures are localised in the image, such as bar code localisation and recognition or road network extraction.

摘要： A vehicle presence detector, usable in particular for monitoring the occupancy of parking spaces or for the traffic control and regulation, comprises two magnetic field vector sensors (1,2) and the vehicle presence evaluation block (6) equipped with the software or hardware for evaluating the information from the vector sensors. Vector sensors (1,2) lie on a single line (12), they have parallel direction and their vertical distance ranges from 2 cm to 20 cm. Between their outputs and the input of the vehicle presence evaluation block (6) is inserted the block (5) of calculation of the vehicle distance from the detector. The output of the first vector sensor (1) is connected to the input of the first block (51) of converting the uncalibrated output values from the first vector sensor (1) to the calibrated values B 1 proportional to the magnetic flux density, the output of which is connected both to the first input of the summing circuit (52), and to the first input of the differential circuit (55). The output of the second vector sensor (2) is connected to the input of the second block (54) of converting the uncalibrated output values from the second vector sensor (2) to the calibrated values B 2 proportional to the magnetic flux density, the output of which is connected to both to the second input of the summing circuit (52), and to the second input of the differential circuit (55). The output of the summing circuit (52) is via the circuit (53) for dividing by two interconnected with the first input of the divider (57). The output of the differential circuit (55) is via the divider (56) for dividing by number d specifying the distance between the first vector sensor (1) and the second vector sensor (2) connected to the second input of the divider (57), the output of which is connected to the first input of the vehicle presence evaluation block (6). The output of this divider (57) and simultaneously the input of the vehicle presence evaluation block (6) is therefore the information L=H/G, where H was obtained as (B 1 +B 2 )/2 and G as (B 1 -B 2 )/d. This information L is proportional to the distance of the detector from the vehicle (8), which is an advantageous classifier for processing in the vehicle (8) presence evaluation block (6).

The secondary winding of the current measuring transformer (4) is connected to the first input gate of the phase detector (8), the second input gate of which is connected to the comparison output of the measuring signal excitation generator (6) formed by the second output terminals (6.2). The output gate of the phase detector (8) is connected via the integrator (9) to the control input of the voltage controlled oscillator (7). The output of the voltage controlled oscillator (7) is connected to the input terminals of the measuring signal excitation generator (6), the first output terminals (6.1) of which are connected to the input terminals of the power amplifier (5).
