A pushing vehicle is described for transporting at least one child, including: a wheeled chassis including a chassis frame and a plurality of wheels that are rotatably mounted relative to the chassis frame to support the chassis frame above a ground surface and which enable the chassis to be moved along the ground surface; a passenger support for supporting a child; wherein the passenger support is attachable to the frame in a mounting position by a single tool-less attachment mechanism for attaching an underside of the passenger support to the chassis frame, to support the passenger support generally above the wheeled chassis. Also described are related modular seating systems and a supporting compartment.

A method of manufacturing a printhead includes connecting an ink supply and driving electronics to a predetermined number of inkjet ejector sites. Each ejector site includes a fluid inlet and an electrical connector. The predetermined number of ejector sites connected to the ink supply and driving electronics is less than the total number of ejector sites available for use in the printhead.

A steerable rotate-to-advance device for accessing a bodily passageway, said steerable rotate-to-advance device comprising:an inner flexible tube having a distal end and a proximal end, a longitudinal axis extending between said distal end and said proximal end, and a lumen extending from said distal end to said proximal end;an outer flexible tube having a distal end and a proximal end, a longitudinal axis extending between said distal end and said proximal end, and a lumen extending from said distal end to said proximal end; the outer flexible tube being disposed coaxially over the inner flexible tube and being rotatable with respect thereto;an external thread disposed over said distal end of said outer flexible tube, said external thread having a sufficient structural integrity, and a sufficient surface profile, such that when said outer flexible tube is disposed in a bodily passageway, rotation of said outer flexible tube about said longitudinal axis will result in longitudinal motion of said outer flexible tube along said bodily passageway; andat least one articulating cable secured to the distal end of said inner flexible tube at an attachment point, and extending proximally along said inner flexible tube, such that pulling the at least one articulating cable proximally causes the inner flexible tube to be bent toward the radial position of said attachment point, whereby to cause the steerable rotate-to-advance device to be steered in the direction of the attachment point.
摘要:
An inkjet external ink manifold is provided that allows for use of a jet stack that does not internally contain ink manifolds. The external ink manifold has a manifold body that includes one or more ink manifold chambers and includes ports arranged to connect the chambers to one or more ink reservoirs. The external ink manifold further includes an adhesive layer overlying and sealing the ink manifold chambers. The adhesive layer includes a plurality of ports arranged to connect the external ink manifold chambers to the jet stack.

A method includes advancing an apparatus having an elongated member transorally into the stomach. The apparatus includes a distal end effector having first and second members configured to engage tissue. The first and second members are movable relatively toward one another generally in a first plane. The method includes moving the distal end effector relative to the elongated member in the first plane such that the distal end effector is retroflexed out of alignment with the elongated member to position the first and second members for engagement with the tissue. At least one of the first and second members carries a fixation device for fixing engaged portions of tissue together.
摘要:
A method of detecting the formation of ice on the blades of a wind turbine 1. The wind turbine has at least one turbine blade 2 mounted to a rotor and provided with at least a first strain sensor 4 for measuring mechanical strain of the turbine blade. The method comprises detecting changes in an output signal of the strain sensor 4 due to changes in the mass of the turbine blade 2 caused by the formation of ice on the turbine blade.
摘要:
The present invention relates to a method for identifying an entity comprising placing an internal tag within the entity and placing an external tag proximate the entity wherein the internal tag and external tag are coupled.

In accordance with the invention, there are free-standing ductile composites, liquid dispensing devices, and methods of making free-standing ductile composites, liquid dispensing devices. The method of making a free-standing ductile composite can include providing a substrate and releasably bonding one or more piezoelectric elements to the substrate. The method can also include kerfing the piezoelectric elements in a predetermined pattern to form a kerfed pattern, filling the kerfed pattern with a polymer to form a polymer-piezoelectric composite, and lapping the polymer-piezoelectric composite. The method can further include releasing the polymer-piezoelectric composite from the substrate.
摘要:
A dressing blade for finishing and reconditioning new and used abrasive grinding and cutting tools has a slab-shaped shank with an extension protruding longitudinally from the shank. Superabrasive grains are disposed on the surface of the extension and held in place by a brazed metal composition. This composition is formed by brazing a powdered mixture of brazing metal components and active metal components. Specific extension configurations are provided which allow aligning the superabrasive grains in single layer arrangement for precise dressing and simple fabrication of the tool. The novel dressing tool exhibits excellent wear characteristics.
