Abstract: An air brake security locking system retains semi-trailers in a fixed position to prevent theft and is connected to an air brake line of the semi-trailer. The system includes a battery-powered valve which isolates air lines within the braking system at a low-pressure condition, thereby maintaining continuous braking of the wheels. The system includes a locked control box to secure and protect a user interface used to activate the system by entry of a numeric code using a keypad or by using a bypass key lock. A wireless remote actuation device is also utilized to activate the system from a distance. In a deactivated state, the system allows the braking system of the semi-trailer operates as normal. In an activated state, the system securely applies the spring brake units of the semi-trailer preventing movement and possible theft.

Abstract: A power supply system uses improved Class G amplifier architecture for high bandwidth operation with low distortion. The power supply system switches between multiple power supply rails, depending on the signal level handled by the power supply system. The lowest usable supply rail voltage is chosen to minimize power dissipation in the output driver, thus optimizing efficiency. Each supply rail has an associated driver capable of sourcing current to the amplifier output. When a supply rail is selected, its associated driver is enabled and other driver(s) not associated with the selected supply rail are disabled via separate disable control signals. The disabling of the deselected driver may be delayed until current above a predetermined threshold is sensed at the output of the enabled driver. In addition, the frequency of switching between the power rails may be limited via various means designed to limit distortion in the power supply system.
