for said inertial sensor, and for processing said sensor data in combination with said forward direction vector to determine
acceleration of said vehicle in a forward direction independent of a frame of reference of said inertial sensor;

whereby said brake controller is adapted to generate said control signal to said towed vehicle braking system in a manner
that is substantially insensitive to acceleration of said vehicle in a lateral direction and to said orientation of said inertial
sensor without prescribing a mounting orientation of said brake controller relative to said towing or towed vehicle.

SYNCHRONOUS DC-DC CONVERTERS, AND SYSTEMS AND METHODS OF CONTROLLING SAME

REDARC TECHNOLOGIES PTY L...

1. A synchronous DC-DC converter for converting an input voltage (Vin) into an output voltage (Vout), the converter having a continuous current operative mode (CCM) and a discontinuous current operative mode (DCM), the converter
including:
an active switch receiving a first gate signal for turning on the active switch for a first time interval (Tq1), the first gate signal having a period (Tprd);

a synchronous rectifier receiving a second gate signal for turning on the synchronous rectifier for a second time interval

ROTARY SWITCH

REDARC TECHNOLOGIES PTY L...

1. A rotary switch, including:
a main contactor including a main contact carrier and a main cam;
a shaft rotatably journaled in the main contactor and extending axially through the main contactor, wherein the shaft is rotable
between a first position in which the switch is in an OFF position and a second position in which the switch is in an ON position,
and wherein the main contact carrier and the main cam are driven apart axially upon rotation of the shaft to the second position
to drive main contacts on the main contact carrier to contact against main contacts on corresponding terminals of the switch
when the switch is in the ON position;

an auxiliary contactor including auxiliary contacts;
an auxiliary cam secured at a distal end of the shaft, wherein the auxiliary cam co-acts with the auxiliary contactor upon
rotation of the shaft between the first and second positions to open and close the auxiliary contacts; and

the main cam has a rod receiving portion defined by at least one arcuate portion having a radially extending opening driving
surface, a radially extending closing driving surface and a gap therebetween, wherein the rod urges against the closing driving
surface upon rotation of the shaft to the second position and urges against the opening driving surface upon rotation of the

cam co-acts with the auxiliary contactor to break open the auxiliary contacts while the rod rotates in the gap of the rod
receiving portion until reaching the opening driving surface of the rod receiving portion so that the auxiliary contacts break
open before the main contacts on the main contact carrier break open from the main contacts on the corresponding terminals
