PROBLEM TO BE SOLVED: To provide a method for detecting a symmetric object of known shape preferably related to a road, particularly of a road sign, in an image of environment within a visual range of an imaging device arranged particularly in an automobile. SOLUTION: An image is picked up by an imaging device, and at least one image area including pixels or a part thereof and exceeding symmetry preset each time is determined in the picked-up image or in an image formed by image processing from the picked-up image. Each related image portion is determined in relation to at least one image area or a part thereof for subsequent shape recognition, and shape recognition is carried out only in at least one related image portion to detect a latent image of the symmetric object each time.

PROBLEM TO BE SOLVED: To eliminate necessity of an independent reaction agent level sensor. SOLUTION: A fluid delivery system for delivering a metered dose of fluid from a supply tank 28 to a downstream chamber or vessel 10, comprises a pump apparatus 20 comprising a pump plunger 32 which is operable to perform a pumping stroke under control of an electromagnetic actuator 36, including a solenoid 36a, to effect delivery of the fluid and a control unit 24 for supplying an input signal 58 to the solenoid to initiate a current flow to the solenoid and thereby initiate movement of the pump plunger. An electronic device 54 provides an output signal to indicate that movement of the pump plunger has stopped at an end of the pumping stroke of a pump plunger, and a timer determines a time difference between the input signal 58 being supplied to the solenoid and the output signal being output by the electronic device 54. A processor 26 compares the time difference with a predetermined time difference and determines, as a result of the comparison, whether or not the pump plunger has performed a valid pumping stroke in which an intended volume of fluid is displaced, whether or not the stroke can be used for total flow quantity calculation.

PROBLEM TO BE SOLVED: To provide an optimizing system for oxygen-rich fluid distribution. SOLUTION: The oxygen distribution system is provided with a first sieve bed and a second sieve bed, respectively composed to selectively receive a supplied fluid, and separate a substantially oxygen-rich fluid from the supplied fluid. A patient conduit having a patient outlet is alternately and selectively communicated with the first and the second sieve beds to let fluid flow. The system is provided with a breath detection device communicated with the patient conduit to let fluid flow. The breath detection device is composed to compute the breathing rate to respond to inhalation of breathing so as to trigger an output of substantially oxygen-rich fluid in a specified volume alternately from one of the first and the second sieve beds. The system is further provided with a device composed to measure the flow of the output of at a specified interval. The output having target flow rate and the flow rate occurs in a dynamically adjusted oxygen distribution step to a patient, and the step relates to the target flow rate and the flow rate of the output, and/or the breathing rate.

Abstract:
PROBLEM TO BE SOLVED: To provide an injector driving method capable of preventing fuel supply from being fluctuated. SOLUTION: A voltage is controlled according to a voltage/charge pair time profile, in a control method for an injector piezoelectric actuator for controlling a fuel amount injected into a cylinder. High current drive is executed up to a level required for staring the injection, then low current drive is carried out, and a low gradient of a voltage/charge pair time is generated until completely charged. The fluctuation in the minimum distribution pulse is reduced compared with conventional constitution with a constant gradient, and a gradient of a gain curve is reduced. Alternatively, the high current drive is executed up to a level required for amplification-switching a liquid pressure lift amount. A voltage/charge is held, or even a zero current phase or a negative current phase may be introduced between the two current phase, in alterative constitution. A charge applied to the actuator is controlled by a fluctuating voltage drop, or the voltage may be directly controlled. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a cooling assembly for cooling an electronic component with direct air. SOLUTION: The cooling assembly is provided with a housing which supports a nozzle for directing a cooling air onto an electronic component. A casing rotatably supports a shaft, which in turn, supports a compressor, an expander, and an electric motor, to circulate an air and deliver the cooling air to the nozzle. The assembly is excellent in that it has air bearings which support the shaft in the casing on a thin film of air, thereby maintaining a contamination-free housing. COPYRIGHT: (C)2008,JPO&INPIT
