Abstract: According to various aspects, exemplary embodiments are disclosed of systems and methods for safety interlocking of operator control units for remote control machines. In an exemplary embodiment, an operator control unit configured to enable and disable a safety lock mode for a remote control machine includes a processor, a network interface, an input interface and memory including processor-executable instructions which cause the processor to disable motion controls of the remote control machine while maintaining wireless communication with the remote control machine to allow core non-motion controls of the remote control machine, and in response to a predefined sequence of activations of the multiple inputs during a specified time period, enable motion controls of the remote control machine. Methods for disabling a safety lock mode may include one or more required input interface actions in order to reduce a chance of accidentally disabling the safety lock mode.

Abstract: According to various aspects, exemplary embodiments are provided of board level shields having single piece constructions. In an exemplary embodiment, a shielding enclosure includes sidewalls and an integral top surface. The sidewalls include upper and lower portions cooperatively defining an interlock therebetween. The upper sidewall portions depend downwardly from the integral top surface. The interlock releasably attaches the integral top surface and upper sidewall portions to the lower sidewall portions. By disengaging the interlock, the integral top surface and upper sidewall portions may then be completely separated from the lower sidewall portions. The integral top surface and upper sidewall portions may also be reattached to the lower sidewall portions by engagement of the interlock.
