Systems for mounting a helmet-mounted device to a helmet are disclosed. One such system comprises a frame configured to be movably coupled to the helmet, and an interconnect mechanism rotatably coupled to the frame. The interconnect mechanism is configured to receive the helmet-mounted device. The interconnect mechanism is rotatable relative to the frame between a use position for the helmet-mounted device and a stow position for the helmet-mounted device.

The present invention includes a knob assembly which provides rotational movement and translational travel along an axis of dual and independent rotary knobs. The present invention controls electronics within a housing, without requiring protrusion into the housing. Having no protrusions into the housing avoids exposure of the electronics within the housing to environmental contaminants or electromagnetic interference. The components of the dual independent push button rotary knob assembly may operate without need for O-rings, gaskets, or any other applied sealants to prevent containments from entering the housing. Assembly of the knob assembly is simplified, because the rotary knob assembly may be installed and replaced without any tools and without need to access the interior of the housing. Furthermore, if any part of the assembly is damaged, the rotary knob assembly, in part or whole, may be replaced without compromising any seal provided to the exterior surfaces of the housing.

A buck regulator for converting an input DC voltage, V, into an output DC voltage level includes a coupled inductor for outputting the DC voltage level, and an error amplifier for sensing an error in the outputted DC voltage level and a pulse width modulator (PWM) providing a pulse waveform having a duty cycle responsive to the error. Also, included are a Vvoltage driver for outputting the Vvoltage level responsive to the pulse waveform, and a super voltage driver for outputting a super voltage level, Vss, responsive to the pulsed waveform, wherein the super voltage level is higher than the Vvoltage level. The outputted super voltage level is complementary to the outputted Vvoltage level. Also included are dual MOSFETs, which have gates for, respectively, receiving the super voltage level and the Vvoltage level. The dual MOSFETs drive the coupled inductor for outputting the DC voltage level. Furthermore, a pulse shaper is coupled between the PWM and the voltage drivers for forming a sharp pulse having a rise time that is faster than a rise time of the pulse waveform. The sharp pulse is provided as a control signal for activating the voltage drivers.
