An object of the invention is to always maintain an outer pin holder and a housing in a speed reducer section at their predetermined positions, to prevent damage to such components as revolving members, outer circumferential engagers, and motion conversion mechanism upon a large axial load due to turning or sudden acceleration/deceleration, etc., and to eliminate rattling noise caused by the housing and the outer pin holder. A casing immobilizing member which is fixed to an inner surface of a speed reducer section casing and a housing immobilizing member which is fixed to an outer surface of a speed reducer section housing are provided between the speed reducer section casing and the speed reducer section housing. The casing immobilizing member and the housing immobilizing member are bonded with each other via a rubber member.

An image acquisition sensor of a digital image acquisition apparatus is coupled to imaging optics for acquiring a sequence of images. Images acquired by the sensor are stored. A motion detector causes the sensor to cease capture of an image when the degree of movement in acquiring the image exceeds a threshold. A controller selectively transfers acquired images for storage. A motion extractor determines motion parameters of a selected, stored image. An image re-constructor corrects the selected image with associated motion parameters. A selected plurality of images nominally of the same scene are merged and corrected by the image re-constructor to produce a high quality image of the scene.

Image Acquisition Method and Apparatus

A method of combining image data from multiple frames to enhance one or more parameters of video image quality includes acquiring a first image at a first exposure duration, as well as acquiring a second image at a second exposure duration shorter than the first exposure duration and at a time just before, just after or overlapping in time with acquiring the first image, such that the first and second images include approximately a same first scene. In this way, the second image is relatively sharp and under-exposed, while the first image is relatively well-exposed and less sharp than the second image. Brightness and/or color information are extracted from the first image and applied to the second image to generate an enhanced version of the second image.

Low-light video frame enhancement

An image processing technique includes acquiring a main image of a scene and determining one or more facial regions in the main image. The facial regions are analysed to determine if any of the facial regions includes a defect. A sequence of relatively low resolution images nominally of the same scene is also acquired. One or more sets of low resolution facial regions in the sequence of low resolution images are determined and analysed for defects. Defect free facial regions of a set are combined to provide a high quality defect free facial region. At least a portion of any defective facial regions of the main image are corrected with image information from a corresponding high quality defect free facial region.

Image Processing Method and Apparatus

A digital image acquisition system includes a portable apparatus for capturing digital images and a digital processing component for detecting, analyzing and informing the photographer regarding motion blur, and for reducing camera motion blur in an image captured by the apparatus. The digital processing component operates by comparing the image with at least one other image, for example a preview image, of nominally the same scene taken outside the exposure period of the main image. In one embodiment the digital processing component identifies at least one feature in a single preview image which is relatively less blurred than the corresponding feature in the main image, calculates a point spread function (PSF) in respect of such feature, and de-convolves the main image using the PSF. In another embodiment, the digital processing component calculates a trajectory of at least one feature in a plurality of preview images, extrapolates such feature on to the main image, calculates a PSF in respect of the feature, and de-convolves the main image using the PSF. In another embodiment the digital processing unit after determining the degree of blur notifies the photographer of the existing blur or automatically invokes consecutive captures.

To provide a motor cooling structure for an electric vehicle which can efficiently cool a driving motor in a power unit case of the electric vehicle. A transmission case cover having an air filter is mounted on the left side surface of a transmission case at a portion adjacent to a fan, and a ventilation gap is defined between a rear portion of the transmission case cover and the transmission case. The transmission case cover is formed with a cooling air inlet facing the above ventilation gap. When the fan is rotated in synchronism with a crankshaft, an outside cooling air is introduced from the cooling air inlet into the transmission case cover and is then passed through the air filter to enter the transmission case, thereby forcibly cooling a CVT 23. Thereafter, a part of the cooling air introduced into the transmission case is discharged from a central air outlet to the outside of the transmission case, and the remaining cooling air is drawn to the driven portion of the CVT 23.

A control apparatus for a continuously variable transmission ensures good acceleration performance during staffing operations, and following an engine stall occurring before a gear ratio of the continuously variable transmission is shifted back to a low speed. The control apparatus includes sensors, a gear ratio return control unit, and a one-way clutch. One sensor detects a gear ratio of a continuously variable transmission. Another sensor detects whether an engine is in a stationary state. The gear ratio return control unit drives a motor in a backward direction when the engine is in the stationary state and the gear ratio of the continuously variable transmission is other than a low gear ratio. The one-way clutch turns idly relative to a backward drive of the output shaft. The gear ratio return control unit brings the motor to a stop when the gear ratio of the continuously variable transmission lowers sufficiently.

To provide a power switchover apparatus for a hybrid vehicle, which can perform power switchover smoothly. Target follow-up control is started, and when the engine speed reaches a clutch-in speed of a starter clutch, the input power shaft of a continuously variable transmission starts rotation. The speed of the output power shaft also begins to gradually rise in response to the starting of rotation. The engine speed then reaches a target, and transmission ratio raising control of raising the transmission ratio based on the difference between the motor speed of a drive shaft and the speed of a driven side pulley is started. The motor speed Nm of the drive motor and the speed of the driven side power transmission pulley then become equal to each other and the one-way clutch is placed into a connected state. Consequently, the transmission ratio raising control is stopped and normal control is entered.

Power switchover apparatus for a hybrid vehicle

To provide a power module driving control apparatus and a hybrid vehicle capable of obtaining sufficient accelerator response despite adoption of a speed sensing type clutch for connection and disconnection of a power drive between an engine side and a driving wheel side. When a rotational speed on an input side of a centrifugal clutch falls short of a set value, at which the clutch can be connected, and an acceleration request is made by a rider, a control unit controls a motor generator so as to bring the rotational speed on the input side of the clutch near to the set value. When the motor generator is made to function as a motor, rotation on the input side of the clutch is assisted. When the motor generator functions as a generator, an amount of electricity generated is decreased.

A clutch control device (18; 75, 76) and a clutch control correction amount calculating method (CL1, CL2) calculate a control correction amount for a clutch by detecting a load required for engagement of the clutch (CL1, CL2). Oil pressure detecting means (150) detect a clutch oil pressure in driving a clutch (CL1, CL2) in its engaging direction against a biasing force of a return spring (12) for normally disengaging the clutch (CL1, CL2). Stroke end detecting means (140) detect that the clutch (CL1, CL2) has reached a stroke end position where clutch disks (B1, B2) are in contact with each other when the amount of change in clutch oil pressure becomes larger than a predetermined value. Clutch control correction amount calculating means (130) calculate a work load generated in the return spring (12) according to the clutch oil pressure detected at the stroke end position and then calculates a control correction amount for the clutch (CL1, CL2) according to the difference between the work load calculated above and a predetermined reference value.
