    • A data transmission system for a vehicle includes a plurality of control systems installed on the vehicle, and a network bus connecting the plurality of control systems with each other for circulating a transmission right through the plurality of control systems to thereby perform transmission of a message between the plurality of control systems. According to a first aspect, each of the control systems starts transmitting data when it is detected that the transmission right is not generated or lost from the system, and continues transmitting the data when no collision of data transmitted from the present control system with data transmitted from the rest of the plurality of control systems, or when by mediation for avoiding the collision is detected, it is determined to continue data transmission. According to another aspect, the maximum number of times of retransmission to be permitted is determined according to a type of failure in transmission identified, and the retransmission is performed so long as the number times of retransmission of the data does not exceed the maximum number of times of retransmission to be permitted. According to still another aspect, the message comprises a first response field for receiving a first acknowledging response output from a control system having received the transmission right, and a second response field for receiving a second acknowledging response output from a control system having received data.

    • A data transmission system for an automotive vehicle includes a plurality of control units installed on the vehicle, and a transmission line connecting the plurality of control units with each other. The transmission line comprises a pair of signal lines to which digital data signals having opposite polarities are delivered for transmission of data. Each of the plurality of control units comprises a first receiver for receiving both of the digital data signals having oppositive polarities and outputting a first difference signal indicative of a difference between the digital data signals, a second receiver for receiving one of the digital data signals and outputting a second difference signal indicative of a difference between the one of the digital data signals and a predetermined reference level set thereto, and a third receiver for receiving the other of the digital data signals and outputting a third difference signal indicative of a difference between the other of the digital data signals and a predetermined reference level set thereto. Detecting of which of the pair of signal lines is faulty, is carried out based on the first difference signal output from the first receiver, the second difference signal output from the second receiver, and the third difference signal output from the third receiver.

    • The player piano provides a string-striking mechanism including a hammer driven by corresponding one of eighty-eight keys, and a photo sensor is provided in the vicinity of and also positioned to face with the predetermined member of this string-striking mechanism to be rotated responsive to a key-depression. This photo sensor outputs a signal which is varied in response to a distance of the predetermined member therefrom, so that the output thereof may have a peak value. Based on the peak value, first and second output values are respectively calculated, wherein these values corresponding to the predetermined two measuring points arranged between the photo sensor and the predetermined member are outputted from the photo sensor before and after the peak value respectively. On the basis of the distance between two measuring points and passing time to be passed when the sensor output is varied from the first output value to the second output value, a string-striking velocity of said string-striking mechanism representing a performance state of the play piano is to be computed. Thus, fixation and adjustment of the sensor can be made easily, thereby the string-striking velocity of the hammer can be sensed accurately.
