Abstract: Abstract of the disclosure A data transmission method modulates maximal-sequence codes which are phase shifted with individual phase shifting quantities based on plural data for transmission, then convolutes the modulated maximal-sequence codes to obtain transmission data, and afterwards, receives the transmission data and obtains cross-correlation of the transmission data with a maximal-sequence code which has the same phase shifting quantity as the phase shifting quantity of the maximal-sequence code which corresponds to the data for transmission.          A data transmission method modulates maximal-sequence codes which are phase shifted with individual phase shifting quantities based on plural data for transmission, then convolutes the modulated maximal-sequence codes to obtain transmission data.  The method previously obtains a time sequence code based on a weighting factor for every data and maximal-sequence codes which are phase shifted with corresponding phase shifting quantities, then obtains cross-correlation of the transmission data and the time sequence code.

Abstract: SHIFT SCHEDULING METHOD FOR CLUTCH ENERGY LIMITATION            Abstract of the Disclosure An improved method of scheduling ratio shiting in a vehicle transmission adaptively adiusts the normal shift schedule to avoid shift-related overheating of the torque transmittinq devices of the transmission.  In normal operation, transmission shifting is scheduled by comparing measured vehicle speed and engine throttle position values with predefined load data.  In the background, the transmission controller determined the cumulative thermal energy stored in the torque transmitting devices.  If excessive energy is indicated, the normal shift schedule is modified to allow extended operation in the lower speed ratios.  When the cumulative energy indication returns to a normal level, normal shift scheduling is resumed.
