Abstract: A video reproducing apparatus performs continued reproduction of a video title in association with continued reproduction of applications. When a Power-OFF or Reproduction-Stop of the video reproducing apparatus event occurs at a time point when the video title is reproduced to a midpoint of a chapter, continued reproduction information of an HD DVD disk is identified, such as a title and a chapter being reproduced, and is stored in a memory at that point in time. When the power is turned ON without replacing the HD DVD disk, the application displays a chapter menu of the title, and a script including a command for starting reproduction of the chapter is activated by the application according to an operation of a button of the chapter menu.

Abstract: A main switch of a cruise control system is combined with one of a number of the control switches such as a set/coast switch, wherein when the combined switch is once turned ON, the combined switch functions as a main switch, and when the combined switch is twice turned ON, the main function of the combined switch is operated. On the other hand, when the combined switch is once turned ON and this state is continued for more than a predetermined time, the combined switch functions as a main switch at first, and after the predetermined time has passed, the main function of the combined switch is operated.

Abstract: An automotive vehicle speed control system, in which steady speed drive control is effected. When a vehicle steady speed is increased to the next steady speed, a target signal for the next steady speed drive is increased by a predetermined value immediately after generation of a steady speed incremental signal, followed by increasing the target signal by amounts per time thereby to increase the steady speed.

Abstract: A diagnostic monitoring system, for detecting and displaying malfunctions or abnormal operations occurring in various engine operation control computers, includes a microcomputer, actuators and sensors. Each of the engine operation control computers performs a diagnosis program as a part of their control programs and produces a signal whenever a malfunction or abnormal operation is detected. A central supervisory system receives such signals from the engine operation control computers and stores them separately for the individual control computers. A display unit displays the stored signals in response to instructions from the central supervisory system.

Abstract: When a load to an engine of a vehicle running at a constant speed increases and a vehicle speed slows down below a preset vehicle speed for a constant speed running condition, a gear of an automatic transmission is shifted down. A shift-down signal for causing the gear to shift down is held for a predetermined time to prevent the shift-up of the gear in cases when the vehicle speed momentarily recovers the preset vehicle speed.

Abstract: A digital circuit for the prohibition of operation of a motor vehicle by an intoxicated person may be fabricated by combining an ignition switch with an engine locking and unlocking means, timing means, sensing means and an indication means. The normal ignition circuit of a motor vehicle is interrupted by an engine locking and unlocking means. A timing signal is generated by the timing means in response to signals received from a clock and a sensing means which in turn is responsive to the performance of the operator in a motor ability test such as the ability to maintain a predetermined amount of steady pressure on a brake pedal. If the operator is successfully performing the test, an indication means produces a first cognizable signal which indicates a successful performance.

Abstract: Automobile speed control to maintain actual automobile speed at a desired automobile speed, in which a superposed electrical analog signal formed by a first electrical signal indicating actual automobile speed and a feedback signal indicating fuel injection duration in an engine of an automobile is supplied to a comparator which compares it with a second electrical signal indicating desired automobile speed and memorized on a capacitor. The differential signal or error signal at the output of the comparator circuit is supplied to a servomotor which controls the position or opening of a throttle valve of the engine. The feedback signal is supplied from an injection time signal generator circuit which, in response to a fuel injection command signal from an electronic fuel injection control device associated with the engine, generates an electrical analog signal corresponding to fuel injection duration.

The device includes a driving suitability discriminating means for discriminating the suitability of the operator to drive the motor vehicle, a neutral switch for detecting if the transmission is in a neutral position and a motion preventing means responsive to both the suitability discriminating means and the neutral switch such that the engine of the motor vehicle can be started if the transmission is in neutral but the motor vehicle cannot be driven unless the operator is discriminated to be suitable by the suitability discriminating means.

Abstract: In a skid control system a pressure modulator reduces the pressure applied by a master cylinder to a wheel cylinder when the wheel velocity as measured by a wheel detector decreases faster than a deceleration predetermined by a deceleration control. A control unit which regulates the pressure modulator corrects the predetermined deceleration when the wheel has exceeded the slip ratio at which the coefficient of friction is maximum so as to achieve an optimum deceleration that corresponds to the road surface condition. The control unit induces the pressure modulator to reduce the pressure of the brake fluid and restore the wheel velocity when the coefficient of friction of the wheel reaches the maximum. Emergency braking is thus performed with an average slip ratio at which the coefficient of friction is maximum.

Abstract: A warning display system provides a warning when it detects an abnormal condition in an operating element closely related to the safe operation of a vehicle. An abnormal condition of an operating element is detected by one of a plurality of sensors each provided at a corresponding operating element. Detected signals of the sensors are fed as input to the fixed contacts of a rotary switch. The sliding arm of the rotary switch and a rotary drum are connected to a rotary driving device. The rotary driving device is driven step by step by the output of an energization circuit which generates a pulse signal. The drum has a plurality of display items indicated on its circumference, which display items respectively correspond to each fixed contact of the rotary switch. A display window is provided adjacent the drum for visual observation of one of the display items at a time.

Abstract: In a deceleration detecting device, magnetic induction electromotive force is utilized as a signal for expanding an air bag, and magnitude of this magnetic induction electromotive force is proportional to a speed variation ratio of a movable magnetic substance transferred by deceleration exceeding a predetermined value of a vehicle in order to decrease a detecting time.
