摘要： A rotational gravity gradiometer includes a first member, a second member, a drive member and a motor. The first member is disposed above the second member orthogonal to and centered with respect to the second member. The first member includes support arms extending from the center of the first member. The second member includes a second pair of support arms extending from a center point of the second member. A mass unit is attached at a distal end of the respective first member and second member. A sensor element is attached between each mass unit a connection point of the opposite member for sensing movement of the mass unit. The drive member is coupled to the motor to drive the first member and the second member rotationally. The respective sensor elements generate a signal in response to deflection of the support arm induced by an external mass.
摘要翻译： 旋转重力梯度计包括第一构件，第二构件，驱动构件和马达。 第一构件设置在与第二构件正交并且相对于第二构件居中的第二构件的上方。 第一构件包括从第一构件的中心延伸的支撑臂。 第二构件包括从第二构件的中心点延伸的第二对支撑臂。 质量单元附接在相应的第一构件和第二构件的远端处。 传感器元件安装在每个质量单元之间，相对构件的连接点用于感测质量单元的移动。 驱动构件联接到电动机以旋转地驱动第一构件和第二构件。 相应的传感器元件响应于由外部质量引导的支撑臂的偏转而产生信号。

摘要： An implant removal device includes a body, a first arm, a second arm, an actuation interface, and an extraction member. The first arm is supported at the body and configured to move relative to the body between a retracted position and a skin gripping position. The second arm is supported at the body and configured to move relative to the body between the retracted position and the skin gripping position. The actuation interface is supported at the body. The actuation interface is configured to receive a first actuation input thereat to cause at least one of the first arm and the second arm to move from the skin gripping position to the retracted position. The extraction member is supported at the body and located between the first arm and the second arm.
