Abstract: A data transmission and distribution system that includes a transmitter and a receiver. The transmitter transmits a count value associated with a data clock of the transmitter to the receiver over an asynchronous link as part of an information payload that also includes audio or video information. The data clock is synchronously recreated at the receiver using only a system clock associated with the receiver and the transmitted count value.
Abstract: The invention discloses a helicopter rotor blade static balancing fixture. First, the blade is rooted to provide a basis for accurate station or spanwise measurements. Then, weight information is measured by the load cells, and the distance from the weight measurement to the leading edge of the blade is measured by linear transducers, respectively, and communicated to a computer. The computer calculates the spanwise moment, compares the calculated value to the factory standard spanwise moment, and calculates and displays a recommended weight adjustment. The computer calculates the chordwise moment, compares the calculated value to the factory standard chordwise moment, and calculates and displays a recommended weight adjustment.
