Abstract: A stroller has a frame structure with two laterally spaced apart sides and a frame extension on each side. Each frame extension projects rearward and terminates at a free end. The frame structure is collapsible laterally from a side-to-side in-use spacing between the frame extensions to a side-to-side compact spacing less than the in-use spacing between the frame extensions. A push handle is on the free end of each frame extension. A cross-brace extends between and interconnects the frame extensions. The cross-brace has a central section and a pair of flanking sections pivotally connected to one another. The cross brace is selectively reconfigurable from a stiff condition to a loose condition with the frame extensions in the in-use spacing. The stiff condition maintains the in-use spacing between the frame extensions and the loose condition permits the frame extensions to collapse to the compact spacing.

Abstract: An intake air passage, formed through a motorcycle body frame, reduces changes in pressure within an air routing duct member due to opening and closing of a throttle, and also reduces pipe resonance of the air routing duct member. The air routing duct member extends longitudinally from the intake air passage and directs fresh air to another air passage. The air routing duct member includes openings that communicate with hollow sections provided in a portion of an adjacent support structure, such as an instrumentation support member. When the throttle is opened rapidly, air from the hollow sections is temporarily supplied to the air routing duct member, reducing changes in internal air pressure in the air routing duct member due to throttle operation. Resonance chambers are formed above the air routing duct member, and communicate through communication pipes with a space within the air routing duct member to reduce duct pipe resonance.

Abstract: In a hybrid vehicle, an ECU performs speed-change control and selectively changes a speed-change mode between a stepless speed-change mode and a fixed speed-change mode in accordance with the travel condition of the hybrid vehicle. At this time, in the condition that the fixed speed-change mode is selected, if an accelerator off operation is performed, a release preparing process is performed, and a reaction element which receives the reaction torque of engine torque in a power dividing mechanism is changed to a sun gear on a motor generator side. Moreover, if an accelerator off speed or a brake pedal operation amount exceeds its own reference value, the speed-change mode is transferred into the stepless speed-change mode, predictively and unconditionally, before a normal speed-change condition is met.

Abstract: A two-piece snowboard includes an improved bottom shape and connector. The bottom surface of each snowboard section facilitates three primary functions: riding in a straight line, turning, and stopping. The bottom surfaces are concave or substantially flat, and grooves or ribs are provided along bottom edges of the sections to provide for turning and/or braking. Thus placed, the grooves and/or ribs do not interfere with straight line riding. The connector is somewhat stiff, and resists twisting. An example of a suitable connector is a length of reinforced hydraulic hose. The connector allows both vertical and horizontal flexing to facilitate riding over irregular terrain, while resisting twisting between sections to facilitate control.
Abstract: The invention relates to a method for machining the running surfaces (9) of winter sports appliances such as skis or snowboards, in which a blank track (20) is subjected to a machining process in order to obtain a predetermined surface microstructure which improves the gliding ability.
