Abstract: A multi-piece valance body is configured to extend lengthwise along the front of an adjacent headrail (e.g., of a covering for an architectural opening) between opposed lateral ends. The valance body may include a first valance body portion and a second valance body portion, with the body portions configured to be coupled together via a joint defined between the body portions in the lengthwise direction across the length of the headrail (e.g., a width of the architectural opening) to form the complete valance body structure.

Abstract: A system linking a serial interface with a processor that is parallel in nature is described. A system memory having a receive buffer stores data from a UART destined for processing by a central processing unit. A control state machine interrupts the central processing unit to initiate processing of the data in the receive buffer when the receive buffer reaches a certain state, such as storing a full frame of data. Command characters indicative of control conditions in the data stream are detected by discrete hardware in a receive command processor, and the memory address in the receive buffer is forwarded to the central processing unit. The resulting system substantially improves the speed and efficiency of the transfer of data between the UART and the central processing unit.
