IPC: F02D29/02
Filed: 1996-09-24
Granted: 2000-06-11
Abstract: This invention provides a vehicle steering control equipment. Its purpose is to prevent a lag control of decreasing output of the vehicle engine, so as to have a much larger forward driving power when a vehicle is moving in low velocity and running conditions variation, such as turns and acceleration. Based on the traffic information of the forecasted driving path from a navigation system, if the path's condition variation, such as turns, is determined, then the vehicle is regarded as in non-lag condition. At this moment a general mode's vehicle control will proceed in lieu of a lag vehicle control. If it is determined that the vehicle should not proceed under a present road conditions, conditions will be anticipated and the lag condition will imposed.

Title: A method and device for detecting a ringtrip
Inventor: BOKINGE BO
IPC: H04M1/24
Filed: 1996-12-20
Granted: 1999-08-11
Abstract: A ringtrip detector comprises a reference counter for controlling a battery current generator, which shapes the ring signal, a zero pass detector for detecting zero passes in a voltage at a node, which is proportional to the telephone line current and two other counters. The zero passes of the voltage create a pulse at both the positive and the negative zero crossing of the zero pass detector. The reference counter is gated into a memory, when these pulses appear. The zero passing of the previous and the present ring cycle are stored in the memory. A counter decides the difference between the previous and the present ring cycles zero passes. If the zero pass difference between the present and previous ring cycles is greater than a fixed value, the output will indicate a "phase difference" and if it is less than the fixed value, it will indicate "no phase difference". Another counter counts a predetermined number of successive ring cycles with "no phase difference" at the start of a ring burst signal, and after establishing the ring burst signal, another predetermined number of successive ring cycles with "phase difference" is counted to detect the ringtrip.

Title: Semiconductor memory device

IPC: G11C16/02
Filed: 1998-01-23
Granted: 2000-06-01
Abstract: The invention provides a semiconductor memory device which can prevent malfunction caused by power supply voltage noise. The solution is that in the latch circuit of sensing portion, the output of the first latch circuit 601 is inputted into the second latch circuit 602 and the output of the second latch circuit 602 is inputted into the third latch circuit 603. Therefore, in the condition of selected memory cell being the first threshold VT0, because the output of first latch circuit is at ""L"" level, the output of the second latch circuit will be at ""L"" level by the data; further, the output of the third latch circuit will be at ""L"" level by the data. Therefore, even if the output of the second and third differential amplifiers varies because of power supply voltage noises, the data can be correctly read out without being influenced by the power supply voltage noises.
