    • Disclosed is an electronically adjustable joint, and associated systems and methods. A joint position of a multiple-axis joint, e.g., a 3-axis joint, can be tracked, as the joint moves through two or more dimensions. In an illustrative embodiment, the joint can provide a mechanical equivalent of a physical joint, e.g., a shoulder, elbow, hip, or knee, which can accommodate motion in rotational angle and/or tilt angle. In some embodiments, the joint includes electronically adjustable friction. An illustrative application provide electronically adjustable joints for an aging simulation suit, wherein one or more joints can be controllably stiffened in selective ranges, such that a wearer of the suit can experience the effects of aging, arthritis and/or other ailments. In an illustrative embodiment, a sensor can use four discrete 2-axis magnetometers to calculate the position of the magnet on the arm of the joint, to continuously sense and track the angle of the joint. In some embodiments, the system includes a mechanism, e.g., a servo, which can controllably tighten a socket around a ball joint, wherein the system can controllably adjust friction on the joint.
    • 公开了一种电子可调接头,以及相关的系统和方法。 当关节移动通过两个或多个维度时,可以跟踪多轴关节(例如3轴关节)的关节位置。 在说明性的实施例中,关节可以提供机械等效的物理关节,例如肩部,肘部,髋部或膝部,其可以适应旋转角度和/或倾斜角度的运动。 在一些实施例中,接头包括电子可调摩擦。 示例性应用为老化模拟服提供电子可调接头,其中一个或多个接头可以在选择性范围内可控制地加强,使得衣服的佩戴者可以体验到老化,关节炎和/或其它疾病的影响。 在说明性实施例中,传感器可以使用四个离散的2轴磁力计来计算磁体在接头臂上的位置,以连续地感测和跟踪接头的角度。 在一些实施例中,该系统包括机构,例如伺服机构,该机构可以围绕球头接头可控地拧紧插座,其中系统可以可控地调节接头上的摩擦力。
