摘要： A class of transporters for carrying an individual over ground having a surface that may be irregular. Various embodiments have a motorized drive, mounted to the ground-contacting module that causes operation of the transporter in an operating position that is unstable with respect to tipping when the motorized drive arrangement is not powered. Methods of controlling the transporter are described that allow the dynamic behavior of the transporter to more closely match preferences of a rider. These methods include providing preferential responsiveness to change in pitch angles and pitch rates.

摘要： A process for forming a catheter tip is described wherein a mold having an internal surface complimentary to the desired external surface of the catheter tip is formed such that it has two temperature zones. A first higher temperature zone is positioned proximally of the catheter distal tip and a lower temperature zone is positioned distal to the higher temperature zone. A catheter to be tipped is placed upon a mandrel or needle and the mold is heated. Upon insertion of the catheter and mandrel into the mold. The catheter material softens and begins to flow within the mold. The higher temperature portion supplies the heat necessary to soften the catheter material and it flow to the lower temperature zone wherein the lower temperature causes the catheter material to become more viscous or resolidify. Upon becoming more viscous, the catheter material, at the very tip, acts as a dam to prevent further flow of material thus eliminating flash from the mold end.
摘要翻译：描述了一种用于形成导管尖端的方法，其中形成具有与导管末端的期望外表面互补的内表面的模具，使得其具有两个温度区。第一较高温度区域定位在导管远侧末端的近侧，较低温度区域位于较高温度区域的远侧。将待倾倒的导管放置在心轴或针上，并且模具被加热。将导管和心轴插入模具中。导管材料软化并开始在模具内流动。较高温度部分提供软化导管材料所需的热量，并且其流向较低温度区域，其中较低温度导致导管材料变得更粘稠或重新固化。在变得更粘稠时，导管材料在最尖端处起到阻挡作用，以防止进一步流动材料，从而消除模具端部的闪光。

摘要： A method for fore-aft stabilization of a vehicle for motion in a specified direction over an underlying surface. The vehicle has at least one forward wheel and at least one aft wheel, and the forward wheel is characterized by a force normal to the instantaneous direction of motion of the vehicle. A motor actuator drives each aft wheel, and a controller governs the motor actuator or motor actuators in such a manner as to dynamically stabilize the vehicle, according to a uniform control law, when the forward wheel is in contact with the underlying surface or not. A torque is applied to the aft wheel on the basis of vehicle pitch or the force on the forward wheel normal to the direction of motion. Additionally, a periodic rotational modulation may be applied to the aft wheel, and a stabilizing torque provided based on a detected response, either of vehicle pitch or of normal force on the front wheel. Left and right motor actuators may independently control left and right aft wheels to continue turns as governed by user steering, whether or not forward wheels are in contact with the ground.
