摘要： A motor control circuit comprises a current command circuit generates a current command signal proportional to a selected motor speed. A comparator generates a comparator output signal proportional to the difference between the current command signal and a signal proportional to current flow in the motor. An output terminal of the comparator is operatively connected to a logic circuit which generates a control signal having a duty cycle that varies proportional to the comparator output signal. A drive circuit has an input terminal to which the control signal is applied and an output terminal connected to the motor. The drive circuit generates a motor drive signal proportional to the control signal for driving said motor. A current command control circuit has an input terminal to which the current control signal is applied and an output terminal to which the current command signal is applied. The current command control circuit generates a signal proportional to the control signal and reduces the current command signal when the proportional signal is less than the current command signal.

摘要： A method for determination of a repeater time delay in a mobile communication network, without affecting a correct positioning of a mobile terminal, is disclosed. The method includes the steps of determining an initial estimated position of a mobile communication terminal to be measured its position, estimating a respective distance between a serving base station and an adjacent base station and the mobile terminal using the initial estimated position, estimating a time difference of arrival of a serving base station signal and an adjacent base station signal received by the mobile terminal using the estimated distances, receiving the time difference of arrival of the serving base station signal and the adjacent base station signal measured from the mobile terminal, calculating a difference between the estimated time difference of arrival and the measured time difference of arrival, and determining the difference as a repeater time delay existing in the serving base station of the mobile terminal, if said difference is larger than a predetermined threshold value. The present invention makes it possible to estimate in advance the clock error in the terminal owing to the repeater time delay in AGPS system, so it can provide the terminal with more precise Acquisition Assistance Information (AAI). Further, such estimation of clock errors in the mobile terminal makes it possible to prevent the failure in acquisition of GPS signals that may occur due to the significant deflection error in the clock operation of the mobile terminal.

摘要： Provided is a function of providing a recordable time considering remaining memory capacity. To implement this function, an average reception rate of broadcasting data received for a predetermined time (e.g., several seconds) is calculated, and the recordable time is calculated using the camculated average reception rate and the remaining memory capacity. By doing this, even if the amount of broadcasting data to be recorded varies according to broadcasting programs, the amount of broadcasting data to be recorded can be predicted, and thereby, a user can efficiently record a desired broadcasting portion by actively determining whether the broadcasting is recorded.
