Granted: 1999-02-16
Abstract: An automatic clutch controller 60 for a vehicle that reduces the oscillatory response to clutch engagement.   The automatic clutch controller receives inputs from an engine speed sensor 13 and a transmission input speed sensor 31 and develops a clutch engagement signal controlling a clutch actuator 27 between from disengaged to fully engaged.  The clutch engagement signal at least partially engages the friction clutch in a manner to cause the measured transmission input speed to asymptotically approach a reference speed employing an approximate inverse model of this oscillatory response.  In a launch mode, corresponding to normal start of the vehicle, the reference speed is the measured engine speed.   In a creep mode,  corresponding to slow speed creeping of the vehicle, the reference speed is a creep speed reference based on the throttle setting and the engine speed.          The two modes are selected based upon the throttle setting.  The automatic clutch controller preferably includes an integral error function and a differential engine speed function, which together adaptively adjust clutch engagement corresponding to vehicle loading.

Title: Burst band-width reservation method in asynchronous transfer mode (atm) network
Inventor: IKEDA CHINATSU
IPC: H04L12/54
Filed: 1994-01-04
Granted: 1999-12-14
Abstract: In an ATM network using a burst-level band-width allocation, a source terminal reserves, before a burst transmission, band-widths according to a peak rate of the burst and then sends the burst therethrough. When the transmission is finished, the band-widths are released. Where there exists a link to which the peak rate is not assigned.      NACK is sent to the terminal and the reserved band-widths are released. On receiving the NACK, the terminal allocates a band-width with peak rate lower than that of the first request after a back-off time is elapsed, thereby minimizing the block probability of the transmission. The source terminal declares a minimum band-width together with the peak rate (maximum band-width) in the band-width request operation.      Each node allocates the peak rate when the remaining band-width of a link controlled by the node is sufficient to allocate the peak rate. Even if the remaining band-width is insufficient, when the band-width is not less than the minimum band-width, there is allocated a band-width equal to or more than the minimum band-width and equal to or less than the peak rate according to the remaining band-width, thereby transferring the burst.
