20150321648 | Braking System - The present disclosure relates to a braking system and, more particularly, to a braking system for engaging a brake mechanism as a waiting brake for a load carrying vehicle. The braking system comprises first and second brake mechanisms. A controller is configured to control the operation of the second brake mechanism such that, if a predetermined fault condition is determined whilst the first brake mechanism is engaged, the controller automatically engages the second brake mechanism. | 11-12-2015 |
20150322975 | Control Valve for a Hydraulic System - A hydraulic system associated with an ejector truck is configured to move an ejector plate and a rear gate. The hydraulic system may cause the rear gate to begin moving before the ejector plate. As well, the hydraulic system may reduce the delay in initiating the movement of the ejector plate and the rear gate, and increase the moving speed of both the ejector plate from the retracted position to the extended position and the rear gate from the closed position to the open position. | 11-12-2015 |
20150323069 | Braking System - The present disclosure relates to a method of disengaging a brake mechanism used as a waiting brake for a load carrying vehicle. In a vehicle comprising an automatic transmission system having at least one drive mode and a neutral mode, changing the mode of the transmission system from neutral mode to a drive mode automatically disengages the brake mechanism. | 11-12-2015 |
20150323070 | BRAKING SYSTEM - The present disclosure relates to a braking system and, more particularly, to a braking system for engaging a brake mechanism as a waiting brake for a load carrying vehicle. The braking system utilises an electrohydraulic brake control mechanism comprising at least one automatic retard control valve to engage the brake mechanism, which is activated by a dual function apparatus which also controls another operation of the vehicle. | 11-12-2015 |

20120242308 | PROTECTION SYSTEM AND METHOD FOR DC-DC CONVERTERS EXPOSED TO A STRONG MAGNETIC FIELD - A protection system and method for protecting a direct current to direct current voltage converter (DC-DC converter) from a potentially damaging excessive output current due to exposure to a relatively strong magnetic field is disclosed. The system includes a detector circuit configured to monitor a signal characteristic of the DC-DC converter, and a linear regulator having an output coupled to the load output of the DC-DC converter. The system further includes a control system configured to disable a load output of the DC-DC converter and enable the output of the linear regulator when the detector detects that the signal characteristic has moved outside a predetermined threshold range. Moreover, the control system is further configured to disable the output of the linear regulator after a predetermined time period, and enable the load output of the DC-DC converter after the predetermined time period. | 09-27-2012 |
20140111178 | TRANSITIONING FROM ENVELOPE TRACKING TO AVERAGE POWER TRACKING - An envelope tracking power supply and an offset capacitive element are disclosed. The offset capacitive element is coupled between a switching output and an analog output of the envelope tracking power supply, which operates in one of an envelope tracking mode, a transition mode, and an average power tracking mode. During the envelope tracking mode, the envelope tracking power supply provides an envelope power supply signal using both the switching output and the analog output. During the transition mode, the envelope tracking power supply drives a voltage across the offset capacitive element from a first voltage to a second voltage, such that during a transition from the envelope tracking mode to the transition mode, the offset capacitive element has the first voltage, and during a transition from the transition mode to the average power tracking mode, the offset capacitive element has the second voltage. | 04-24-2014 |
