A lightweight, compact electric drive unit provides high reduction ratios for a bicycle, light electric vehicle or autonomous device. A cycloid gear reducer includes one or more cycloid gears within a housing. The cycloid gears interact with gear teeth on the inside surface of the housing, and ride on a cam shaft having eccentric lobes. Output pins extend through apertures in the cycloid gears, from an input carrier to an output carrier. An electric motor powers the cam shaft, while the output carrier powers a drive train.

The present invention provides improved, real time sensing of pressure supplied to the hydraulic operator of a clutch for a motor vehicle driveline power take off. A proportional sensor in the hydraulic line to the power take off clutch actuator provides a data signal in real time of the actual pressure applied to the clutch actuator. This signal is provided to the power take off control module (PCM) and/or to the transmission control module (TCM). The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.

A drive chain tensioner assembly for all-terrain and utility vehicles, wherein the drive chain tensioner provides a tension spring between the axis of rotation and a distal portion of a mounting bracket, wherein the mounting bracket and tension spring are coplanar. The proximal portion of the mounting bracket is rotatably connected about a second pivot point spaced apart from a first pivot point associated with the axis of rotation by way of a tension arm. A bracket head may interconnect the second pivot point and the mounting bracket. The tension spring and second pivot point affords the present invention with functional self-adjustability as a result of the foregoing.

There is presented various embodiments disclosed in this application, including an improved crankshaft system using a load connecting member which provides a greater maximum torque angle than a conventional system, thereby improving efficiency and power.

A hybrid vehicle is provided in which deterioration of vehicle mounting characteristics is suppressed. A drive device of the vehicle includes a power splitting mechanism having a sun gear to which a first motor-generator is linked, a carrier to which an output shaft is linked, and a ring gear to which an engine is linked, and a speed reduction mechanism that transmits the torque of the output shaft to a differential mechanism while reducing the rotational speed of the output shaft. The speed reduction mechanism is built up as a chain transmission mechanism which includes a driving sprocket that rotates together with the output shaft, a driven sprocket that is provided to the differential mechanism, and a belt chain that is fitted around these sprockets.

A device for creating more natural three-dimensional image effects which may be recorded, for example, by video cameras. The device has an intermittent image pathway occluder for receiving at least two image pathways which alternately and intermittently occludes the two image pathways, a horizontal imaging-shifting component for shifting at least one of the image pathways leftward or rightward, a vertical imaging-shifting component for shifting the image pathways upward and downward, and an image pathway compositing component which forms a coincident superimposed composite three-dimensional image after the image pathways have been shifted by the horizontal and vertical imaging-shifting components, and after passing through the intermittent image pathway occluder. Also, a device for enhancing the more natural three-dimensional effect of such images which are created and which may be recorded and/or displayed.
