    • The present disclosure provides a navigation method and system which does not require a remotely located tracking system, or additional targets or other devices to be installed on the patient or object being tracked. The system uses one flexible component in physical contact with the patient/object and measures relative position as a function of forces that are generated by the flexing component as it is bent. The system translates forces into navigational commands for a robot, other manipulator, or for human manual navigation. A method for transforming a pre-planned motion pathway into a sequence of forces for this mode of navigation is also described. This system is also applicable in the field of manufacturing robotics, where the locations of objects or assemblies may not be precisely known or constant. The method and system disclosed herein can be used to maintain known position of an object/assembly or to navigate movement of a robot relative to an object/assembly as in the case of machining.

    • A control system (200) using fixed point computation avoids overflow conditions by limiting the internal quantities ensuring that contributing calculations from various parts of the control loop never add up to an overflow. Various parts of a control loop e.g. proportional terms can be prioritised over other parts, e.g. integral and differential terms and ensuring that the overall total resulting when the separate terms are summed together never exceeds the maximum or minimum imposed limits. Variable limit calculator circuits (211,219) revise the limits according to the output of the higher priority control path(s). The revised limits cascade down through each contributor, eventually allowing the lowest priority control path the smallest authority. The control system may be applied to control of a drive motor (111) for an aircraft inceptor (103).
    • 使用定点计算的控制系统(200)通过限制内部量来避免溢出情况,确保来自控制回路的各个部分的贡献计算永远不会累加到溢出。 控制回路的各个部分,例如 比例项可以优先于其他部分,例如, 积分和微分条款,并确保将单独条款汇总在一起所产生的总体总数绝不超过最大或最小限制。 可变限制计算器电路(211,219)根据较高优先级控制路径的输出来修改限制。 修订的限制通过每个贡献者逐级下降,最终使最低优先级的控制路径成为最小的权限。 该控制系统可以用于控制飞机感应器(103)的驱动马达(111)。

    • In some embodiments, an apparatus includes a solenoid and a solenoid controller. The solenoid is configured to move an actuator a distance between a first position and a second position when a voltage is supplied to the solenoid. The solenoid controller is implemented in at least one of a memory or a processor, and includes a feedback module and an output module. The feedback module is configured to receive a feedback signal associated with a solenoid current after the voltage is removed from the solenoid. The feedback module is further configured to determine whether the distance is less than a maximum distance between the first position and the second position (i.e., a "stroke"). The output module configured to produce an output signal when the feedback module determines that the distance is less than the maximum distance.
