Abstract: An electric-over-hydraulic braking system for trailers and towed vehicles is disclosed. The system comprises off-the-shelf components, such as a standard linear actuator and master cylinder, for reduced cost and greater reliability. In a dual master cylinder configuration, the braking system controller calculates an average pressure across each channel, and compares that value to a control signal from an in-cab controller. The linear actuator is extended or retracted in response to a signal proportional to this difference. The system may include break-away functionality, as well as diagnostics to indicate low pressure and transducer circuit malfunction conditions.

Abstract: Apparatus and method for assembling circuit structures in an assembly line process. The apparatus responds to a set of program instructions by selecting components in a predefined sequence from a plurality of components and aligns each selected component to correspond with an orientation defined by the program instruction set required to mount the selected component at a specific location on a circuit board. The apparatus is controlled by the program instruction set to electrically configure and program each selected and aligned component in real-time in accordance with a configuring and programming subset of the program instruction set and to install each configured component at a predefined circuit board location.
