Abstract: Assemblies for supporting a load relative to a roof of a vehicle, and vehicle roof tray assemblies are disclosed. Disclosed assemblies include an elongate member and an engaging mechanism. The elongate member defines a support surface for supporting the load, and has a pair of opposed, diverging retention surfaces extending away from the support surface. The engaging mechanism is configured to abut the retention surfaces to engage the elongate member. A slat for a vehicle roof tray is also disclosed.

Abstract: A system comprising an interface module (IM) for receiving input and generating outputs, the IM being associated with processor (17) and memory (19); a controller module (18) (CM) that is operable independently of and communicatively connected to the IM and that is associated with processor (20) and memory (22) and that receives inputs and generates outputs to control accessories wherein each memory stores a copy of a parameter list (38) and rules governing generation of the outputs, wherein each of the IM and CM is configured such that responsive to each input, the processor of the respective module IM, CM defines a state in the associated copy of the list and communicates with the other module IM, CM to cause the state to be defined in the other copy, wherein each rule requires a state to be present in the list for generation of an associated output by each module.
