    • Systems for locating buried utilities in conjunction with associated electromagnetic marker devices are disclosed. A marker device may include a marker device antenna and an electronic circuit operatively coupled to the marker device antenna. The electronic circuit may include at least two resonant circuits, including a first resonant circuit formed in combination with the marker device antenna for receiving an excitation signal at a first frequency from a marker excitation device. The received excitation signal may be converted into a power supply by a power circuit for powering the electronic circuit. Responsive to the received excitation signal, a processing element provided in the electronic circuit may generate an output signal at a second frequency, which is different from the first frequency. The generated output signal may be tuned by a second resonant circuit and provided to the marker device antenna.
    • 公开了用于与相关联的电磁标记装置一起定位掩埋的公用设施的系统。 标记装置可以包括标记装置天线和可操作地耦合到标记装置天线的电子电路。 电子电路可以包括至少两个谐振电路,包括与标记器件天线组合形成的第一谐振电路,用于从标记激励器件接收第一频率的激励信号。 接收到的激励信号可以通过用于给电子电路供电的电源电路转换成电源。 响应于所接收的激励信号,设置在电子电路中的处理元件可以产生具有不同于第一频率的第二频率的输出信号。 产生的输出信号可以由第二谐振电路调谐并提供给标记装置天线。

    • User interface devices (UIDs) for sensing position or motion of an actuator assembly in multiple degrees of freedom are disclosed. In one embodiment a UID includes a frame having a top and bottom assembly, an actuator assembly disposed within a volume between the top and bottom of the frame having magnets disposed therein, a sensor array for sensing magnetic fields from the magnets in multiple axes, and a processing element for receiving the sensed magnet fields and generating a UID output signal corresponding to a position, translation, rotation, deformation, or other action of the actuator assembly.
